Alipay and WeChat free cash withdrawal strategy (latest version of 2019)

  Tomorrow is National Day! Are you ready to celebrate your mother’s birthday?

  In order to celebrate the National Day better, minibus will talk to you about saving money today. Alipay and WeChat are commonly used payment software, but as the versions are constantly updated, there are fewer and fewer channels for free cash withdrawal. The friends said that although the handling fee is a small sum, if it can be saved, many a mickle makes a mickle … However, the free cash withdrawal channel has not been completely blocked. Today, the minibus will take care of everyone, how to withdraw cash for free.

  Alipay free cash withdrawal

  Let’s talk about the method of Alipay’s cash withdrawal first: 1. Redemption of points for free cash withdrawal. Whenever we use Alipay to shop or sign in, we can get points every day. These points can be exchanged for free cash withdrawal, and the higher the level, the higher the amount that can be exchanged for cash withdrawal. For example, if the minibus is a gold member of Alipay, it can exchange 1,000 points for 1,500 yuan of free cash withdrawal.

  However, many people usually don’t pay attention to the point collection, so there are not enough points for redemption, or the free withdrawal amount for redemption is simply not enough. Then you can look at the following way. 2, credit card overpayment Now Alipay has a free amount of 2,000 yuan to pay back the credit card every month. If you have a credit card, you owe 1,000 yuan and pay back 2,000 yuan, then paying more than 1,000 yuan is an overpayment. This overpayment will be withdrawn into the bank card. However, it should be noted that not all banks’ overpayment withdrawals are free. For the time being, ICBC, CCB, Minsheng, Huaxia, Shanghai Pudong Development Bank, China Everbright Bank, China Merchants Bank, CITIC and Guangfa are free of charge. However, before the operation, it is best to consult the bank customer service, just in case. In addition, it should be noted that overpayment will pay off the outstanding bill of the credit card. For example, there is a credit card with a line of 10,000 yuan, which has already spent 5,000 yuan. This month’s bill is 1000 yuan, so there is no overpayment if you use Alipay to pay back 2,000 yuan. The cash withdrawal method of the overpayment is also very simple. For example, the minibus uses China Merchants Bank, and I pay for the credit card overpayment with 1000 yuan, so I can withdraw it through the path: Pocket Life APP- My-Audit Repayment-Overpayment.

  China Merchants Bank needs T+2 before it can be withdrawn, and other banks will follow the rules of each bank.

  However, some friends will find this method troublesome when they see it, or there is no credit card at all. Don’t worry, we still have a plan. 3. Alipay’s money collection code uses the money collected by Alipay merchants’ money collection code, and the withdrawal fee is free. If you don’t charge money, you can also find someone to do it together and pay each other, so that both of them will be free of handling fees. Application method: Enter the "payment code" in the search box on Alipay homepage, and the "application for payment code" will pop up in the search results. If you choose to print by yourself, you can save the collection code to the photo album. This method is available to everyone and will be free until April 2021.

  But be careful, don’t take the initiative to open the "flower garden to collect money" in the merchant service, otherwise, you will be charged a service fee of 0.8% of the transaction amount. Small partners who have already opened can go to the "merchant service" page to turn it off.

  4. Yu Libao withdraws cash through Yu Libao, that is, first transfer the money from Alipay balance to Yu Libao, and then transfer it from Yu Libao to the bank card, free of handling fees, and quickly withdraw the limit of 10,000 or 100,000 per day. Yu Libao is similar to Yu ‘ebao, which can be said to be "Yu ‘ebao for merchants", and the income will be slightly higher. However, Yu Libao needs to be opened. If you have opened the online merchant bank before June 2017, you can open it in the online merchant bank: My-merchant service-Yu Libao, start the service. If it is not opened before that time, you can also apply for the "payment code" we just mentioned in Alipay first, and then open it in Alipay: My-Merchant Services-More-Yu Libao.

  5. Online merchant banks withdraw cash through online merchant banks, which is not only free of handling fees, but also arrives in real time. There is also a quota of 100,000 a year, and fees will be charged if it exceeds 100,000. The operation steps are also very simple, just open the online merchant bank in Alipay, transfer the balance of Alipay to the online merchant bank, and then transfer the money from the online merchant bank to its own bank card.

  However, this method is only applicable to those who opened the online merchant bank before June 2017. If this condition is not met, it will not work.

  Wechat free cash withdrawal

  In this life, each of us has only a free withdrawal amount of 1000 yuan on WeChat. For the change that is already in the WeChat wallet, it is necessary to withdraw the fee anyway. What free cash withdrawal method does WeChat have for the new money? 1. The WeChat payment code is also the merchant payment code. Although it can realize free cash withdrawal, WeChat has more restrictions than Alipay. First of all, only some users can open it when invited, not immediately if you want to open it. Open the WeChat search applet "Collection Small Account Book", or find the "Collection Small Account Book" under the QR code collection in "Collection and Payment". Open the small collection ledger. If you can see the column "Apply for official collection code", congratulations, there is a game; If not, there is another way, perhaps to "save the country by curve".

  People who rarely use the WeChat payment code usually can’t see the application entrance of the official payment code, such as the interface of the minibus.

  At this time, it is necessary to click the operation of "clerk management", in which a total of 50 clerks can be added. If it is to withdraw free of charge, just add a close friend, scan the code face to face, or add a push link.

  Wait until the next day to enter the applet, and you may find that there is an "official receipt code" application entrance. If it doesn’t work, try adding a clerk several times. All this makes WeChat think that if you want to open a store, it will help you open the permissions …

  The permission of the clerk can also be set. If you don’t want the clerk, you can just remove it later, but the collection function will still be retained. Each free cash withdrawal limit is 500 yuan, with a maximum of 10,000 yuan a day, and like Alipay, only the money transferred by others with the receipt code can be withdrawn. 2. It is equivalent to "Alipay’s balance treasure" to borrow change to pass change, and it can also be deducted directly from it when consuming. The operation is to transfer the money directly from the bank card to the change account, which not only can make the withdrawal free, but also can make a profit, killing two birds with one stone. Path: I-Payment-Wallet-Coin Pass

  3, bank payment code Many banks can apply for merchant payment code, and interested partners can also try to operate it, and then pay through WeChat or Alipay scan code, and the money can be transferred to the corresponding bank card. For example, ICBC (601398, Share Bar) makes e-payment collection:

  The minibus thinks that if there is not much change in WeChat, it will be easier to spend it on daily expenses. If you are afraid of wasting money in it, it is ok to directly buy the wealth management products in WeChat Wealth Management and earn some income. However, WeChat is still not as atmospheric as Alipay … In the past, when it was promoted, the red envelope was very small, but now it is not soft at all. But there is nothing we can do. Now we are used to WeChat ~ Finally, I wish you all a happy National Day! Let’s meet again after the holiday ~

The courier has arrived! Thank you, the most familiar stranger express brother.

1905 movie network news In this special period, we saw many heroes who fought in the front line, but we often ignored the "unknown heroes" around us who have been providing assistance to us in the rear.

 

In this group of "unsung heroes", we have to mention the courier who is closely related to everyone. They have been escorting our lives, rain or shine, whether during our stay at home or at present when we have gradually resumed work.

 

On March 9th, Li Jie, a courier, attended the the State Council conference and said that the biggest difficulty now is that some communities are not allowed to enter, resulting in too little express delivery. He called for allowing couriers to enter the community on the premise of ensuring the health of couriers, so as to improve work efficiency.


Not to mention the "double 11" every year, they have to face all kinds of "explosive positions", and even the film industry can’t do without their "fastest support".


Everyone remembers the "sudden release" event in Better Days, but many people ignore that it is also because of the strength of this group of people that we can see the film smoothly on the day of the release.

 


The figure of courier brother can not only be seen everywhere in our lives, but also the art comes from life. Last year’s hit tribute drama "In the Distance" is an urban entrepreneurial drama that rarely focuses on the domestic courier industry. It allows us to see the development process of private express delivery enterprises, and they have all achieved today’s achievements through hard work.

 

In addition to this drama focusing on private express delivery in China, they are also the most indispensable roles in many movies.

 

Sorry, we missed you


In European and American countries, whenever a courier cannot reach the recipient, the courier will leave a note — — "sorry,we missed you" (sorry, we missed you).


Therefore, the famous British director ken loach made a film "Sorry, we missed you" with this sentence.

 

In this film, this sentence is not only a sincere apology at work, but also an apology for the children as a father in this family of the film.

 

In the film, my father is a courier. Every day, due to overwork, he can’t take care of the big and small things at home. He shoulders the burden of family economy and is bent on providing a stable life for his family, no longer looking at the landlord’s face and owning a house of his own. We can see that the courier is a profession he lives, and his real identity is the head of the family, the husband of his wife, and the father of his children.

 

At the end of the movie, although the hero lost his job, he didn’t play with his children as in the past, but still went out to work for a living. But this time, he said "sorry" to his family.

 

The rest of my life on a desert island


The film starring Tom Hanks is naturally a film that everyone is familiar with.

 

Chuck, the hero, works for FedEx, and he is as precious as gold on weekdays. A plane crash left him stranded on a desert island, far away from the hustle and bustle of the city, and opened up a new lifestyle. His belief in survival was supported only by the pocket watch and a courier package given to him by his fiancee.

 

Over the past four years, needless to say, his hardships and sufferings have turned into failures many times. When his will gradually collapsed, he was unexpectedly saved.


But when he returned to the real civilized world, he became nothing, and unlike fairy tales, his fiancee would wait for him all the time. Strong Chuck chose the blessing and stuck to his duty as an employee of the courier company, delivering the last package before the crash.

 

What exactly is this unopened express parcel? This is the curiosity that the audience outside the film are concerned about. But whatever it is, for him, it is a hope on a desert island and a sense of professional mission.

 

Two seconds


Courier is a race against time.

 

In the movie Two Seconds, the heroine Laurie is the kind of person who focuses on a simple and happy life. As a cyclist, she has no utilitarian heart, just reveling in this sport, enjoying the speed of chasing and eager to freeze the time. After retiring, she still chose the job of bicycle courier. To this end, she even devoted herself to her only racing car.


The life of a courier will not always be as fresh as it was at the beginning and only enjoy riding a bike. Riding a bike is not difficult for Laurie. She is handy, but she has to bear many unexpected difficulties and injuries at work.

 

Just like every courier, they all love their jobs, but they still encounter some unpleasant things when they rush about in crowded cities every day, either coldly or misunderstood, but because of this love, they all live hard and actively.

 

Of course, when we talk about choosing movies in the express delivery industry because we love bicycles, we have to recommend them again.


The hero turned to be a courier because he failed in stock trading, which led to bankruptcy. Compared with the drama of "Two Seconds", this film pays more attention to realism, which is the kind of freedom for couriers to shuttle through big cities and see the good scenery of a city.

 

Premium rush.


The same bicycle courier is even more thrilling.


The hero met a tricky thing, and was entrusted to send an unknown letter. Unexpectedly, it attracted the eyes of a policeman in new york, which led to a series of chasing stories.

 

This film gives an account of the life of express mail, and adds persistence to their fun of riding a bicycle. Express delivery people are happy, persistent, love their work and enjoy the exciting life face to face with time. They are flesh and blood, love and hate, not all of them are poor at the bottom, but some of them come from university campuses, such as the protagonist and his girlfriend.


Probably like the couriers in our life, although they are service industries, they have the responsibility of being full of goods, and they can enjoy their own philosophy of life only by making a phone call to get them to the consignee faster and better.

 

Life express


The movie "Hard Courier" is also a story about the courier being passively involved in a gang plot.

 

Jason Statham plays a retired special soldier, and now he is engaged in driving a BMW to transport goods. Unexpectedly, in a mission, he accidentally found that the goods he was transporting turned out to be a person. He started a magical adventure in line with the "three rules" in the industry.

 

For couriers in life, the "three rules" mentioned in the film are also the professional rules they pay attention to every day: 1. Never change the agreement; 2. Don’t mention your name; 3. Never open the package.


Because of this spirit of contract, on weekdays, the courier and we have more trust and tacit understanding with each other.

 

Super express


In the movie, when the courier played by Michael Chen met his future mother-in-law, he expressed that he would become "the best courier in China" in the future, and he also published a long declaration:

 

"The most important concept of China’s economy in the Internet age is O2O! What is the most important part of O2O? It is logistics! What is the main component of logistics? It’s us couriers! Without couriers, there will be no cheap and good goods; Without commodities, there is no consumption power; Without consumption power, there will be no future of the real economy. Therefore, it is our ordinary couriers who have set up a day in China’s economy! "

 

This slogan may be the voice of the staff in the express delivery industry.

 

In addition to these films, couriers, as the "most familiar strangers" in our lives, often appear in different films and become the strongest supporting actors.


Perhaps the appearance of these walk-ons is only for better advertising, but we may expect that in the future movie market, there will be works belonging to this group of people, and we can also use movies to tell them, "Thank you, courier brother."

The Bright Future of "Internet Affairs" —— A Summary of China’s Internet Development in the 40 Years of Reform and Opening-up

  "In 1997, I used my company’s’ cat’ to dial up the Internet for the first time." "In 2005, I bought a scarf for the first time online." "In 2013, all my families were replaced by smart phones, and a WeChat group was established." "In 2017, I taught my dad to scan the code to pay for food … Talking about the changes in people’s lifestyles since the reform and opening up 40 years ago. Information acquisition, online shopping, code scanning payment, mobile phone socialization … People’s life scenes have been marked with the Internet.

  The rapid growth of Internet industry in China is the product of reform and opening up. Ma Huateng, chairman of Tencent’s board of directors, once said: "Tencent’s success has many factors, but the historical opportunity of reform and opening up is our greatest asset." Ma Yun, Chairman of the Board of Directors of Alibaba Group, also said: "In the past 40 years, China has opened its market, both internationally and domestically. Without the reform and opening up policy, there would be no us today. "

  From the mouse to the touch screen, this is a great change at the fingertips. From the perspective of overall industrial development, China has been ranked first in the world for 10 years in terms of the number of netizens, broadband netizens and the number of national top-level domain name registrations. Online shopping, smartphone shipments and the number of mobile payments, these new world firsts outline that the Internet is becoming a new engine for China’s economic transformation and upgrading.

  Network infrastructure provides support.

  Cao Fangzhou, a Beijing white-collar worker who moved into his new home this year, made a "bold" decision: not to install cable TV. "There are two’ boxes’ at home. It is enough to watch dramas and variety shows. You can watch them on news phones, as well as live webcasts. It is enough to have a network." Like Cao Fangzhou, many users have migrated their spare time of watching video content from TV to the Internet. The data shows that as of June this year, the number of online video users in China is 609 million, the number of short video application users has reached 594 million, and the number of live webcast users has reached 344 million. The market size of the entire video content industry is expected to reach 201.68 billion yuan in 2018, a year-on-year increase of 39.1%.

  As a heavy traffic application, online video industry needs bandwidth and traffic support. "By the end of September this year, the proportion of national fiber-optic broadband users reached 88%. At the end of 2014, only 10% of users in China used broadband of more than 20M; By September this year, more than 60% of users in China have used broadband over 100M m. Since 2014, China has built the largest and most extensive 4G network in the world in just two or three years. With the help of the policy of speeding up and reducing fees, the average mobile traffic consumption of mobile users in China reached 5.14GB in September, 2.6 times that of the same period last year. " Wen Ku, Director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, said that the rapid development of infrastructure has provided support for various segments of the Internet.

  The online video industry is also enthusiastically embracing technological innovation. Su Hua, CEO of Aauto Quicker, a short video application, said: "Artificial intelligence runs through every link of video production, video understanding, user understanding and accurate distribution in Aauto Quicker. For the identification of video content, 15 million short video content generated every day will be labeled automatically by artificial intelligence and the voice content is recognized." In 2017, the number of patent applications for artificial intelligence inventions and the number of invention patents granted in China reached 46,284 and 17,477, respectively, with a year-on-year increase of 34.9%. Kai-Fu Lee, Chairman of innovation works, also said: "It took only two years for China to’ miraculously rise’ in artificial intelligence. Today, the most valuable artificial intelligence companies in computer vision, speech recognition and drones are China companies."

  E-commerce retail innovation continues.

  213.5 billion yuan! At 0: 00 on November 12th, this huge number appeared on the data screen of Tmall "double 11" Media Center in Shanghai World Expo Center, and the new single-day online shopping transaction volume of China e-commerce platform was fixed here. Data from the Ministry of Commerce show that on this day, the national online retail transaction volume exceeded 300 billion yuan. The US Cyber Monday, the target of double 11, has a transaction volume of only $7.9 billion this year, less than one fifth of that of double 11.

  Taobao was launched in May 2003. In that year, the transaction volume of online shopping in China was only 790 million yuan, but then the consumption of the Internet in China soared. Ma Ruisi, chairman of Procter & Gamble Greater China, was quite impressed: "In the United States, only 7% of Procter & Gamble’s business comes from e-commerce, but it has reached more than 30% in China. Last year,’ double 11′ Procter & Gamble spent 19 hours to reach sales of 1 billion yuan, and this year it only took 70 minutes."

  The rapid development of e-commerce has provided millions of small and medium-sized enterprises with direct access to consumers, including a series of "Amoy brands" such as wheat bags, Handu Yishe, Sheba, Qigege and puppy appliances. In the "double 11" in 2013, Tmall and Taobao sold 35 billion yuan in 24 hours. In that year, the national online transaction volume reached 1.85 trillion yuan, and China surpassed the United States for the first time to become the largest online shopping country.

  The rapid development of e-commerce has witnessed the tremendous energy of consumption upgrading. Li Yongjian, director of the Internet Economy Research Office of the School of Finance and Economics of China Academy of Social Sciences, said: "From the perspective of consumer choice, online shopping has begun to evolve from necessities to enjoyment products, and e-commerce platforms are also transforming from price competition to quality competition."

  According to the report released by the think tank Outlook Think Tank in October, in the past five years, China’s scientific and technological innovation has continuously improved people’s sense of acquisition, among which mobile payment has the highest contribution rate in enhancing people’s sense of acquisition.

  At present, Leopard Secret, the first supermarket robot in China, has started to provide services in wu mart, Beijing. It can answer all kinds of questions of consumers and guide them to find the products they want. This is just the tip of the iceberg of Wumart’s new retail. On the shelf, the electronic price tag can adjust the price at any time; In supermarkets, artificial intelligence cameras count passenger flow and consumption preferences.

  In addition, the unmanned shelves and supermarkets of Binguo Box and Convenience Bees, the small-scale rapid delivery explored by Boxma Xiansheng and Yonghui "super species", and various new formats emerge one after another … Li Fei, a professor in the marketing department of Tsinghua University School of Economics and Management, said frankly: "The retail revolution in China has become the focus of global attention and the’ testing ground’ for the retail industry facing the future."

At the 2018 Hangzhou Yunqi Conference, participants watched the live game of "Tianrang" Go robot in the exhibition hall of the conference. Xinhua News Agency reporter Huang Zongzhi photo

  Integrating "touching the net" to stimulate vitality

  "Changan Ford’s 20,000 employees, upstream and downstream suppliers and distributors are all connected through corporate WeChat. From organization and collaboration to teleconferencing, to direct access to information such as production, sales and service, digitalization has greatly improved Changan Ford’s operational efficiency." Wu Jinhao, chief information officer of Changan Ford, told reporters.

  In the field of manufacturing, a large number of modes of sharing production factors, such as production equipment, design ability and office space, have emerged. In Dongguan, Guangdong, expensive CNC machine tools are providing shared services for small and medium-sized enterprises. Enterprises don’t have to buy machine tools anymore, just pay by the hour or the processing capacity. Wang Gan, chairman of Xinquan Optoelectronics Technology Co., Ltd. said: "Now more than 500 machine tools will cost more than 100 million yuan if purchased directly, but if shared machine tools are used, a set of machines will only cost several thousand yuan a month."

  According to statistics, by 2020, the industrial Internet will account for 22.5% of the total Internet of Things market, and the industrial Internet market in China will exceed 11.3 trillion yuan in the next 15 years. "With the industrial Internet, China’s manufacturing industry has taken the lead in the transformation of production methods." Zhang Yansheng, a researcher at the Academic Committee of the National Development and Reform Commission, said.

  In addition, public services are also being deeply transformed by the Internet. "Running at most once" has become a real commitment of the government to the people, and smart cities are thus more worthy of the name. Jiang Peng, director of the Smart City and Big Data Institute of the Planning Institute of the Urban and Small Town Reform and Development Center of the National Development and Reform Commission, said: "What smart cities really need is the innovation vitality based on data, which can improve the operational efficiency of cities and the decision-making level of city managers through data." Taking Inspur Group as an example, the enterprise helped Jinan become the first local government in China to realize the authorized operation of government data. As the core of operation, the Smart Spring City Operation Management Center has gathered more than 100 million pieces of basic database information from 65 departments in the city. Sun Pishu, chairman of Inspur Group, said that with the deep integration of Internet and government affairs, smart city service providers are also undergoing the transformation to smart city operators.

Ten Advice on Buying Guangzhou Automobile Aian

1. Cheap interior materials

In fact, the interior of the models sold by Guangzhou Automobile Aian has a sense of design, but in fact, the materials used are mainly hard plastics, and the impression is relatively cheap. Compared with many competitors, there is still a clear gap in the materials used for interior decoration.

2. The design is too hard.

Many young consumers think that the appearance of Guangzhou Automobile Aian model is very fashionable, but for the middle-aged main consumer groups whose acceptance is not strong enough, the appearance of Guangzhou Automobile Aian model is a bit too radical, too tough and lacks personality. Sense of stability.

3. The dynamic performance is average

The acceleration time of Guangzhou Automobile AIONY, AIONS, AIONV and AIONLX with a starting price of nearly 300,000 yuan is about 8 seconds. When the model runs at high speed, there will be insufficient power.

4. Poor comfort

Except for the flagship model of Guangzhou Automobile Aian LX, the performance of other Aian models in terms of comfort is not ideal. Chassis suspension can not provide good cushioning performance. During daily driving, people in the car can feel a clear sense of the road. When driving through speed bumps or potholes, the car body will have obvious vibration and bumps, and the ride comfort is not good.

5. loud noise

The tires of Guangzhou Automobile Aian model are quite picky. Tire noise is particularly obvious when driving on asphalt roads. In addition, the sound insulation effect of each model is relatively general, so obvious tire noise and road noise will be produced when the vehicle is driving daily. Wind noise.

6. Low brand awareness

Although GAC Toyota and GAC Honda have made GAC’s reputation a household name, the recognition of two independent brands of GAC Chuanqi and Ai ‘an in the market is relatively low. In addition, the image of Guangzhou Automobile Aian’s network car is deeply rooted in people’s hearts, so Guangzhou Automobile Aian has always been a relatively low-end brand in the eyes of many people.

7. Low configuration

By comparing the configurations of various models of Guangzhou Automobile Yidong with competing products of the same level and price, we can find 360 panoramic images, reversing radar, L2-class assisted driving, keyless entry, and electric adjustment of the co-driver. Safety is only available for high-profile models, while competing products of other brands are basically standard.

8. No spare tire

All models sold by Guangzhou Automobile Aian have no spare tires, only tire repair tools. Although it is possible to add money and spare tires, such an approach will appear insincere in the eyes of consumers, because in most people’s cognition, the spare tires of cars are standard.

9. The service quality of the store cannot be guaranteed.

As GAC Aian, like BYD, mainly operates as an authorized dealer, it is difficult to guarantee the service quality of all 4S shop dealers. Not good.

10. There is a strong smell in the room

Because the interior materials of other models is mainly made of plastic except flagship models such as Aian LX, the interior of the new car will have a strong odor, and after being exposed to the sun, the car will also have a strong odor. Smell. Smell, difficult to remove.

These are the reasons why GAC Aian is not so popular. Although GAC has the experience and foundation of joint ventures such as GAC Toyota and GAC Honda, GAC Aian still has a long way to go in terms of its own brands. This means that the brand still has a lot of room for improvement.

Talent Strategy Behind China Super Project

Photo network _500421607_banner.jpg

Editor’s Note: This article is reproduced by Zhu Xingyu and Entrepreneurial State with authorization.

"Why can’t our school always produce outstanding talents?"

Before he went abroad to study in 1935, Qian Xuesen received a synchronized education in China with the United States. The middle school is studying in the middle school affiliated to Beijing Normal University. President Lin Liru advocates educational reform and inspires students’ interest and consciousness. Students can enter the chemistry laboratory to do experiments at any time, and soak in the library to talk with their classmates about the frontier theory of relativity and Lenin’s revolutionary feat.

When Qian Xuesen graduated from high school, he had already studied science as a sophomore.

Qian Xuesen University studied in Shanghai headquarters of Jiaotong University. Its predecessor was Nanyang College. When it was founded, it was fully benchmarked against the Massachusetts Institute of Technology, known as "Oriental MIT". Due to the integration of courses, Qian Xuesen had already studied the postgraduate courses at MIT when he was an undergraduate, and got his master’s degree one year after coming to MIT.

After studying at MIT, Qian Xuesen felt that the undergraduate teaching of Jiaotong University is the world’s advanced level.

In 2005, Qian Lao said with emotion: "None of the students who have been trained for so many years have achieved academic achievements that can be compared with the masters trained during the Republic of China." Qian Lao asked again, "Why can’t our school always cultivate outstanding talents?"

In the Republic of China, where the illiteracy rate is 90%, the industrial base is weak, and politics is chaotic, Chen Shengshen, who started the school of global differential geometry, came out and put forward Yang Zhenning and Li Zhengdao, whose parity is not conserved. The invention of theorem proving method gave birth to the Wang Hao of theoretical computer science … Why can’t the emerging talents catch up with the masters trained in the Republic of China in the new era?

Qian Xuesen

"If you don’t know what the most advanced ship looks like, how can you build the best ship?"

Shi Yigong, a structural biologist, gave an excited speech at the seminar on talent introduction plan. Just two years after the talent introduction program started in 2008, 326 overseas talents were attracted back to China, including Yao Qizhi, the first Chinese Turing Award winner, and famous biologists Shi Yigong and Rao Yi. However, "there are few first-class talents, but there are many second-and third-rate talents", which has aroused social discussion.

As the representative of the first batch of talents introduced, Shi Yigong firmly supports the talent introduction plan.

"Maybe I was too deeply influenced by the thought of’ born in sorrow and died in happiness’, and I was often worried. I was worried when I reported that China was not as good as abroad. "

Shi Yigong’s worry lies in China’s backwardness in the field of science. "In the high-end research results of life sciences from 2001 to 2006, the gap between Chinese in China and the United States is about 1:10, and Chinese account for about 10%~20% of the United States. On the whole, the high-end research results of life sciences in China are 1%~2% of those in the United States."

Shi Yigong’s conclusion is that "our country is still very backward in many places, so it is necessary to introduce high-end talents". The sustainable development of China in the future must depend on the talents cultivated by itself, but how can you build the best ship if you don’t know what the most advanced ship looks like?

"I’m Chen Lijie, and I want to be a theoretical computer scientist!"

Chen Lijie, a senior student from Yao Ban, Tsinghua, gave a speech on the defense field of the 2016 Tsinghua Undergraduate Special Scholarship, which aroused cheers and prolonged applause from the audience. Chen Lijie, who won the International Informatics Olympiad and was sent to Yao Ban, Tsinghua, has been interested in academics since his freshman year. During his junior year, he became the first China undergraduate to present a paper at the annual meeting of Basic Computer Science.

Chen Lijie said, I feel extremely honored to be born in such a golden age. I dream that I can become a wave in the tide of the golden age and contribute to the wisdom of mankind.

Chen Lijie was born in Yao Ban, Tsinghua, and his immediate seniors include Lou Tiancheng, the famous "building leader", Tang Wenbin, Yinqi and Yang Mu. The former founded Pony.ai, an artificial intelligence travel company, and the latter three are the founders of artificial intelligence unicorn contempt technology. Pony.ai and Defiance Technology, together with the Fourth Paradigm and Etu Technology from ACM class of Shanghai Jiaotong University, occupy half of the world’s artificial intelligence unicorns.

The questions and worries of the first two generations of well-known scientific research talents have gradually been answered in the practice of the new generation of China students. Just like the Jet Lab during the Cold War, Apollo Project and ARPA, the originator of the global Internet, behind the super-projects of these big countries, there are large-scale talent strategies, which bring about technological breakthroughs and then form a golden age of the industry.

Hundreds of millions, all starting from one. Behind the breakthroughs in China’s super projects and national core industries, these leading figures are also closely related to the country’s talent strategy:

Qian Xuesen and "Two Bombs Plan" and "581 Plan";

Shi Yigong and the "Thousand Talents Program";

Chen Lijie, ACM class and Yao Ban’s corresponding "Everest Plan".

A person’s destiny depends on self-struggle, and also takes into account the historical journey.

In 1934, Xueba Qian Xuesen graduated from the Railway Engineering Department of Jiaotong University, and the average score of four years is almost full today. However, he didn’t do well in the exam for public students studying in the United States in August of that year, and he failed in mathematics. Fortunately, he got a high score of 87 points in the course of "Aeronautical Engineering". Professor Ye Qisun of Tsinghua decided to make an exception and Qian Xuesen went to MIT for further study.

After getting his master’s degree in one year, Qian Xuesen joined Professor Von Carmen of California Institute of Technology to study aviation theory, and soon stood out as an authoritative expert in the field of aerodynamics.

Qian Xuesen’s achievements in the United States, in addition to personal efforts, also benefited from the establishment of the "Geng-style study abroad" mechanism, but also benefited from the surging wave of the times in the field of basic scientific research in the United States.

Before 1933, Germany was a well-deserved world science center. At that time, the textbooks of basic science in most countries were German, which was the official language of the world. Even after the defeat of World War I in 1919, German science maintained the highest level in the world, and both relativity and quantum mechanics originated here. In the same period, the United States was in the forefront of the world in applied technology, but its research in basic science was only second-rate.

Before 1933, Germany had 32 Nobel Prize winners, while the United States had only five, and the results were also biased towards the application level.

The change took place in 1933. On April 7th, the Nazis promulgated the Law on Resetting Public Officials, announcing that "communist party, Marxists and people of non-Aryan descent will be dismissed". When a large number of scientists were dismissed, all German universities expressed their collective loyalty to the Nazi government on April 22, and wrote in the Confession: "The sunshine of this nation once again illuminates itself …".

By the beginning of 1938, the number of Jewish scientists expelled had reached 1,800, and the loss of German university teachers reached 39%, among which Einstein, thomas mann, Gustav Hertz and other famous scientists were listed.

With the active operation of American University Aid Committee, Foreign Exile Aid Committee and Rockefeller Foundation, thousands of scientists have been resettled in the United States, and as many as 77% of the 1,400 exiled scientists from Germany and Austria have been accepted by the United States. These exiled scientists brought six Nobel Prize winners, represented by Einstein, and 11 new Nobel Prize winners to the United States. They became the founders of almost all new scientific traditions in the United States and established the outstanding position of the United States in mathematics, physics, chemistry, biology and other disciplines.

Qian Xuesen’s mentor, von Carmen, was a Jewish scientist who went to the United States under the influence of the Nazis. After he went to the United States, he initiated aerodynamic research at California Institute of Technology. Qian Xuesen came to von Carmen’s company in 1936, and soon stood out as Carmen’s favorite student. He gradually became an assistant from a student, and later became a close collaborator in the field of aerodynamics, and jointly published a "pressure correction formula" called "Qian-Carmen formula" by academic circles.

During the Second World War, the United States and the Soviet Union also targeted German applied technical talents such as rockets and atomic energy. During the Yalta Conference in February, 1945, Stalin flatly rejected zhukov’s proposal to March into Berlin, demanding to change the route of March, hoping to include the German missile research base Peminende first.

Not to be outdone, the United States sent an investigation team composed of top American missile experts represented by von Carmen and Qian Xuesen to Germany to investigate the development of rocket technology in Germany. With the approval of President Roosevelt, the "Operation Paperclip", which introduced German experts, was put into practice, and the speed of searching and detaining German scientists began to accelerate, and wernher von braun, the core figure of V-2 missile research and development, was secretly established.

In February, 1945, wernher von braun led a design team of 525 people and accumulated important research materials of missile research for 13 years to the American-occupied area, and the US military transported the equipment that could be taken away to the United States, and destroyed the equipment that could not be taken away. On May 27th, when Soviet troops arrived, they were disappointed to find rubbish everywhere. When Stalin learned the news, he was extremely disappointed and furious: "We defeated the Nazis and occupied Berlin and Penemende, but the Americans did take away German rocket experts here. What could be more humiliating and unforgivable?"

At this time, Qian Xuesen received the rank of Colonel of the US Air Force, personally participated in the inquiry of German rocket expert wernher von braun in Germany, inspected the top-secret Goering Institute of Aerodynamics and wind tunnels in other places hidden in the pine forest and wrote a report, and also interrogated ludwig prandtl, the granddaddy of aerodynamics, together with his mentor von Carmen.

After the war, 642 German experts were introduced into the "paper clip" talent input program in the United States. Different from the Jewish intellectual refugees’ focus on basic scientific research, the German rocket scientists’ focus on applied science has effectively supplemented the missing part of their predecessors in the field of scientific research and filled the gap in the United States. Wernher von braun later invented the Saturn series of launch vehicles in the United States and sent 12 men to the moon in the Apollo program.

The United States is an immigrant country, attracting outstanding talents from all over the world through a good political system and culture, but the supply chain of talents in the United States was cut off during World War II. On the one hand, the boom of World War II made the immigration tide that lasted for a hundred years fall to the bottom, which was the least period of immigration in the United States since 1820. On the other hand, the number of American troops has soared 26 times, which has seriously consumed the number of students enrolled in universities.

In view of the "talent deficit" problem, the American government began to speed up talent training:

  • Promulgated the Military Rights Act of 1944 to provide university education for veterans, and 4 million veterans have successively completed undergraduate or postgraduate education;

  • Establish a scholarship system to attract college students to study science and engineering majors, "equate national security with the training of physicists", and the number of graduates majoring in science and engineering has reached a new high;

  • The Eisenhower Administration pushed Congress to promulgate the National Defense Education Act of 1958, which clarified the relationship between national defense and education, established education as the focus of national defense, and a large amount of funds flowed into American colleges and universities, which expanded rapidly.

Benefiting from the influx of German talents and the shortage of talents after the war, the United States established a "dual-track" talent attraction system by adjusting its immigration law in 1952:

  • Permanent immigration: the annual quota, the first priority principle is that 50% of the quota is used to attract foreign talents, and the other three principles stipulate that the other 50% is used for the reunion of American citizens and legal aliens with their foreign relatives. Those who apply for the first priority principle must have "higher education, technical training experience, professional experience or special talents, and their services are urgently needed by the United States";

  • Non-immigrant visas: A temporary worker (H visa) program will be established, in which H-1 visas will be issued to professionals with outstanding talents, H-2 visas will be issued to skilled and unskilled workers who are in short supply in the United States, and H-3 visas will be issued to foreign workers who receive technical training in the United States.

Attracting foreign talents has become the strategic goal of American immigration policy, and the temporary science and technology labor program marked by H visa is "short, flat and fast", and the government can increase or decrease the number of people according to the economic and political situation, so the H-1B visa that countless engineers are eager for has started.

So far, the United States has formed a training system of education and scientific research based on colleges and universities internally, and established a dual-track talent attraction structure externally. The United States, which has formed a perfect talent system, has made sufficient institutional preparations for the talent war around the outbreak of the Cold War.

In 1949, millions of heroes crossed the river, and the Republic was established on this land that was in great need of development. In 1950, Hua Luogeng returned from the United States and published the famous "Open Letter to Students Studying in the United States" on the eve of passing through the Luohu Port: "Friends, although Liangyuan is good, it is not a land of long residence! In order to choose the truth, we should go back; For the sake of the nation, we should go back, and for the sake of serving the people, we should also go back; Establish our working foundation and strive for the construction and development of our great motherland! "

This letter touched Qian Xuesen, who worked in the United States for 15 years. As early as 1939, after completing his doctoral studies, he wanted to return to China. He was persuaded by his tutor von Carmen and stayed in the United States for 11 years. During these 11 years, he became an authority in the rocket field, an expert in the scientific advisory group of the US Department of Defense, received the title of Colonel of the US Army and was free to enter and leave the Pentagon.

As we all know, Qian Xuesen was detained by the Immigration Bureau on the eve of preparing to return to China, and then began to live under house arrest in the United States for five years. In the same period, the US government will lose the government funds of the Republic of China to support the forced immigration of 3,400 China students stranded in the United States, and attract more than 20,000 intellectuals of the Republic of China, including Zhang Ailing, to immigrate to the United States by supporting public welfare organizations and non-governmental organizations to operate in Hong Kong and Macao.

On February 26th, 1955, the Chinese People’s Liberation Army liberated all the coastal islands in Zhejiang, and the US Congress passed the US-Taiwan Joint Defense Treaty urgently, stating that they had the right to use atomic bombs when the Taiwan Province Strait was threatened. On March 16, US President Eisenhower declared in a televised speech that "nuclear weapons are not only strategic weapons, but also can be used for tactical purposes." , to carry out naked nuclear blackmail on China with non-nuclear capability at that time.

Chairman Mao asked Premier Zhou: "What are our talents in the development of atomic bombs and missiles?"

Premier Zhou replied: "We have the talent advantage in this field. Qian Sanqiang worked with Nobel Prize winner Madame Curie … Professor Qian Xuesen, a missile expert who worked under Dr. Von Carmen, the’ father of rockets’ in the United States, is trying to get him to return to China as soon as possible through various channels …"

On October 8, 1955, Qian Xuesen arrived at Luohu Bridge in Shenzhen, together with nuclear physicists Li Zhengwu and Professor Sun Xiang. Prior to this, 1,424 Chinese who studied and worked overseas returned to China, and they became the backbone of the construction of this ancient and young country. Among the first 172 academicians of China Academy of Sciences in 1955, 158 were returned talents, which played an important role in the construction of industrial system and basic scientific research system in China.

Since then, Qian Xuesen has devoted himself to the research and development of the "two bombs" in China. The connotation of the two bombs has also changed from the initial missile and atomic bomb to the later atomic bomb and hydrogen bomb. In October 1957, after the Soviet Union launched its first satellite, Qian Xuesen led the "581 Project" and "651 Project" of China Satellite successively.

On October 16th, 1964, at 3pm sharp, China’s first atomic bomb exploded successfully, and nuclear blackmail became a term in history.

From 1966 to 1977, the talent system in China collapsed, and the college entrance examination was stagnant for 10 years. In 1977, the chief designer who had just returned presided over a discussion and made a decision to resume the college entrance examination that year. 5.7 million candidates entered the college entrance examination room, and the fate of 270,000 people changed from then on.

With the strong support of the chief designer who had studied in France, the system of studying abroad began to recover. In 1978, the first batch of 52 overseas students were sent abroad at public expense. In 1981, the door to studying abroad at their own expense was officially opened, and the first TOEFL test was held in the mainland. The policy of "supporting studying abroad, encouraging returning home and coming and going freely" was set, and the number of students studying at their own expense exceeded 100,000 in the second year. The chief designer pointed out: "there should be thousands of factions, not just ten or eight."

After a long period of mental depression, young people are greedy for the outside air.

In 1986, Tsinghua’s Zhang Chaoyang won the Li Zhengdao Scholarship, and stood out from 700 top students, becoming one of 100 lucky ones. In the same year, Yan Yan, Xiong Xiaoge and Zhang Yaqin went to the United States. In 1987, Xu Xiaoping first went to the United States and then went to Canada to wash dishes for a long time.

In 1993, Peking Man in new york was popular all over the country: "If you love him, send him to new york, because it is heaven;" If you hate him, send him to new york, because it is hell. "

The huge environmental gap makes few people want to come back. In the 30 years since international students opened the floodgates, only a quarter of them have returned to China. Shi Yigong once mentioned in his speech: Of the 2,251 undergraduates in Tsinghua, 16,700 went to the United States after graduation. Most of them are still in the United States now, but few of them stand out, and contentment is a very big problem.

Shi Yigong’s Ph.D. study in the United States was very painful, and he often failed. However, after the postdoctoral research began, Shi Yigong found that his interest in biology gradually grew, and he quickly made achievements in X-ray crystallography to dissect protein structures. In 1998, Shi Yigong became an assistant professor in the Department of Molecular Biology of Princeton University, and soon became the youngest full-time professor since the establishment of the Department.

Like many people, Shi Yigong originally imagined that the United States was a beautiful, free and democratic country, but in real life, he began to realize the gap between imagination and reality. In 1995, Shi Yigong, who graduated with a doctor’s degree, had the idea of returning to China, but the problem was that there was no matching research environment in China, and he might only be an English teacher, a tour guide or even a taxi driver.

In the United States during the Cold War, national defense was deeply bound up with education and scientific research. Of the huge annual defense funds, more than 11% directly flowed into scientific research in related fields, and 30% of the equipment procurement expenses flowed into Boeing in Seattle, IBM, Hewlett-Packard and Lockheed in Silicon Valley. The spillover of military demand created two science and technology industrial centers, which brought CPU, computer and the subsequent Internet era to the United States.

In the same period of China, economic construction became the absolute center. At the meeting, the chief designer asked the troops to "be patient for a few years", that is, to cut down a lot to save military expenses and support national construction. In order to introduce technology and construction funds and technology, the market-for-technology initiative was implemented, which promoted market growth and brought about the stagnation of localization.

The country’s scientific and technological foundation is indeed very weak. In the 10 years since 1992, the first prize of the National Natural Science Award and the National Technological Invention Award, which were selected every year, fell into an embarrassing situation. The former was only awarded twice in the 10 years, and the academicians Feng Kang and Qin Renchang who won the prize both passed away. The latter was sent three times in 10 years. The founding fathers of "two bombs and one satellite" have all won the honor, but no one can keep up with it. When the self-developed ARJ21 aircraft project was launched in 2002, the designers were either old people in their fifties and sixties, and the rest were young people in their twenties. One generation disappeared.

In China during this period, the scale of high-level scientific research talents was insufficient and the age was unbalanced. In 1992, the average age of research institutes of Chinese Academy of Sciences was 53 years old, and the proportion of university professors over 56 years old in China reached an astonishing 80%, which needed fresh blood urgently. The Chinese Academy of Sciences, the Ministry of Personnel and Education have successively led the "National Jieqing Fund", the "100 Million Project" and the "Changjiang Scholars" program. However, due to the lack of basic environment, the mobilization efforts and achievements are very limited. "There are less than 10 candidates for Changjiang scholars to meet the threshold, which is very obvious compared with hundreds of overseas universities."

After China joined the WTO at the end of 2001, the problem of brain drain in China became more prominent. Since 2000, the number of Chinese students returning to China has gradually declined. By 2004, only 20.9% of them chose to return to China. New Oriental, an English training institution for studying abroad, has become a sacred place in everyone’s heart, and Yu Minhong has been compared to "Moses" in the new era.

What we lose is what we gain. We have exchanged the demographic dividend and the market for the soaring economy, and the GDP has maintained an average annual growth of nearly 10% in the past 20 years. In 1990, China’s economic volume accounted for 1.82% of the world’s total, which increased to 3.69% in 2000, and in 2010, China’s share reached 9.36%. Today, the proportion is 16%, and that of the United States is 24%.

In October 1999, as an outstanding young Chinese expert in the United States, Li Yanhong was invited to return to China to attend the National Day ceremony of the 50th anniversary of the founding of the People’s Republic of China. He was deeply impressed by the advertisements on the websites in the streets. At this time, the pattern of foreign technology dominating the world made him feel the opportunity to start a business. On January 1, 2000, Baidu began to work in Peking University Resource Hotel.

"Historical upheaval is taking place in the motherland". In 2007, Rao Yi, who had been a tenured professor at Northwest University, returned to China. After being applied as the president of Peking University Academy of Life Sciences, he decided that "instead of criticizing overseas, he might as well go back to China to practice".

Encouraged by Rao Yi, Shi Yigong also resigned as a tenured professor at Princeton and returned to teach in the Department of Biology in Tsinghua University: "I hope to come back when I am in my prime and work for the health of the motherland for at least 30 years."

After China’s entry into WTO, the severe talent situation in China has attracted the attention of policy makers. In the Outline of the National Talent Team Construction Plan for 2002-2005, the strategy of "strengthening the country through talents" was put forward for the first time. Later, as one of the basic strategies, strengthening the country through talents was written into party constitution and the report of the 17th National Congress. The rapidly growing economy has become a solid backing and guarantee for the strategic landing.

China’s talent strategy has entered the fast lane of top-level design.

In December 2008, the implementation plan of "Thousand Talents Plan" was issued under the planning of the coordination group for talent work. This is the first talent program coordinated by the central government and implemented by dozens of ministries and commissions, aiming to attract scientific experts who are at the forefront of international research, master core key technologies or have patents.

In 2008, Shi Yigong, Rao Yi and 122 experts, including Turing Prize winner Yao Qizhi who returned to China earlier, were selected into the first batch of talent introduction plans. Up to now, the talent introduction plan has introduced more than 7,000 high-level talents in 13 batches. The leader of the Central Group said: "If there are 1,000 truly useful leading talents among these 10,000 people, it will be great."

The new generation of leaders ensured the continuity of the talent project policy. In his speech at the celebration meeting of the centenary of the founding of the European and American Alumni Association, the General Secretary clearly stated that he would vigorously promote the talent plan and called on "overseas students to integrate their dreams into the Chinese dream", and the central policy of studying abroad, which lasted for decades, was extended and expanded, adding "playing a role".

The "Thousand Talents Program" and the "Young Thousand Talents Program" emerged the basic research achievements such as quantum communication and protein three-dimensional structure, and the application breakthroughs such as OLED screen, Alibaba Cloud, commercial aircraft and algorithm recommendation also began to affect our lives. Breakthroughs in chip packaging, manufacturing and design became the prerequisite for the strategy of manufacturing a powerful country later.

As benchmarking figures, Shi Yigong and Rao Yi have also begun to explore and make efforts for the reform of China’s science and technology system and the frontier research of science and technology.

In 2011, Shi Yigong and Rao Yi, the deans of Tsinghua University and Peking University College of Life Sciences respectively, took the lead in setting up the Tsinghua-Peking University Joint Center for Life Sciences with the support of the Ministry of Education, which became a pioneer pilot in the reform of scientific research and education system: introducing the internationally accepted Tenuer Track system, and "leaving after six years of employment"; Reform the personnel system, separate practice from administration, and professors will enjoy higher autonomy in teaching and scientific research.

The emergence of Life Joint Center has made Tsinghua Peking University’s scientific research ability in the field of life sciences become well-known in China, and world-class young scientists such as Yan Ning, Chai Jijie, Wu Jiawei, Wang Hongwei and Yang Maojun have emerged one after another. Before 2009, only one article was published in the two top journals of Science and Nature in Tsinghua, and more than 70 articles were published in the following eight or nine years.

In 2018, Shi Yigong resigned as the vice-president of Tsinghua University and devoted himself to the establishment of the research university West Lake University. West Lake University is Shi Yigong’s solution to "Qian Xuesen’s question": small but precise, with a high starting point and a priority subject. At the beginning of its establishment, it focused on cultivating doctoral students and top-notch innovative talents, with the goal of benchmarking the well-known research university California Institute of Technology fifteen years later. Among the founding donors, there are Ma Huateng, Wang Jianlin and others.

On the historical tide of going out and returning, people who grasp the trend most accurately have begun to create the future trend.

"Why can’t we win the championship? "

In 2000, at the International ACM Programming Finals held in Orlando, USA, Lin Chenxi of Shanghai Jiaotong University watched three players from St. Petersburg State University win the championship trophy. This is the fifth year that Shanghai Jiaotong University participated in the international ACM competition, and Lin Chenxi led the team to achieve the best result in history: the seventh place in the world.

Lin Chenxi, who won a bronze medal, was not reconciled.

ACM International Programming Competition for College Students has been held since 1970, and it is called "Olympics in Computer Field". ACM competition takes the school as the unit, and three people work together to solve dozens of complex programming problems in five hours, which not only examines students’ programming ability, creativity and teamwork ability, but also serves as a window for world-class universities to show their educational achievements.

Unwilling to think about it, Lin Chenxi, a junior, decided to apply to coach Yu Yong to repeat the grade and transfer to the computer department: "It’s not that we can’t do it, but that we dare not think about it." In order to win, Lin Chenxi maintained the training rhythm from 9 am to 2 am every day for the next two years, excavated potential Lu Jing and Zhou Jian from the newcomers, and formed a world-class team. They refused to sparring and only fought with themselves. "The team that wants to win the championship has no sparring."

In March, 2002, Lin Chenxi led a team to win the ACM Finals, becoming the first Asian team to win the championship. They won the highest prize. When the returning plane landed, Xie Shengwu, president of Jiaotong University, personally greeted them at the airport with flowers. Lin Chenxi recalled that he was "frightened at that time".

Professor Yu Yong, who led the team, knew that it was time to establish a mechanism to train computer scientists and industry leaders. "The other abilities of this competition assessment are not available in the classroom. It seems that we only teach hard things, but we can’t compete with others. No one emphasizes the soft skills of communication, expression and cooperation. "

On April 26, Jiaotong University won the championship. On June 16, Professor Yu Yong submitted an application to the school to set up a computer experimental class. Two days later, he received an approval. In September, ACM class of Jiaotong University began to enroll students.

In the same year, another key meeting took place in Beijing. The only Chinese professor Yao Qizhi who won the Turing Award, known as the Nobel Prize in Computer Science, visited Tsinghua. At the strong invitation of Professor Yang Zhenning, Professor Yao Qizhi resigned as a tenured faculty member of Princeton University in 2004 and came to teach in Tsinghua University.

After Yao Qizhi came to Tsinghua, he wanted to recruit several graduate students, but after the best students were recruited, they found that "the foundation is not enough, and a lot of knowledge that should be known is unknown". From students to research, it takes a long time to change their thinking and mentality. Yao Qizhi thought that we must start with undergraduates and train first-class undergraduates, so as to train first-class doctoral students and first-class researchers.

In 2005, the computer science experimental class was established. This undergraduate class, called "Yao Ban", was personally developed by Yao Qizhi and the teaching plan was written. Yao Qizhi lectures on the course "Theoretical Computer Science", which takes undergraduates for four hours every week.

ACM class and Yao Ban are very similar in training methods:

  • Strengthen the guidance for students to engage in computer research in the direction;

  • In terms of teachers, we should break through the school barriers and introduce a large proportion of visiting professors to teach, and try our best to find whoever speaks well;

  • Freshmen and sophomores place special emphasis on basic courses, such as mathematical analysis and linear algebra;

  • After junior year, he entered the laboratory very early and engaged in scientific research;

  • Attach importance to bilingual education, and all courses in Yao Ban are taught in English;

  • Attaching importance to internship and communication, junior students of the first ACM class collectively went to Microsoft Research Institute for internship, and half of the students in Yao Ban had the opportunity to exchange abroad.

With the implementation of talent programs such as Thousand Talents Program and Youth Thousand Talents Program, outstanding young talents begin to return, and outstanding undergraduates can have access to top research and have top knowledge.

Dai Wenyuan, Lou Tiancheng, Tang Wenbin, Yinqi, Yang Mu … The founders of these enterprises, who occupy half of the world’s AI unicorns, are all from ACM class and Yao Ban, while Rong Rong, Chen Danqi, Zhao Shuang, Kelly Y Zhou, Bei Xiaohui and others have also begun to make breakthroughs and achievements in the frontier research field of computers, expanding the boundary of human cognition to the unknown mystery.

In 2009, ministries and commissions such as education, China Central Committee, and finance organized and implemented the "Experimental Plan for Training Top Students in Basic Subjects", also known as the "Everest Plan", aiming at attracting the best students to join in basic scientific research and exploring various modes to train famous talents. Class ACM and Yao Ban became pioneers and models of "Everest Plan", which pointed out the way for later changes.

The Landing of "Everest Plan" in Colleges and Universities (Part)

In 2009, Tsinghua University launched the "Tsinghua School Talent Training Plan" and established six Tsinghua school classes, namely, Tsinghua School Mathematics Class, Physics Class, Chemistry Class, Life Science Class, Computer Science Experiment Class and Qian Xuesen Mechanics Class. Second enrollment, independent training, and well-known resources, life science class led by Shi Yigong and "Yao Ban" led by Yao Qizhi were included. As a special teaching place, Tsinghua School, the oldest building in Tsinghua, can be selected as a favored child bearing the glory of history.

In 2010, Zhiyuan College of Shanghai Jiaotong University was officially listed, and ACM class was included in the computer science direction of Zhiyuan College. Zhiyuan College has become the top-notch innovative talent training base and "experimental special zone" of Jiaotong University, providing the best university education for outstanding talents and training well-known students with the strength of the whole school. "Zhiyuan honor plan" has become the goal of Jiaotong University students.

In 2010, the Qiushi Science Class of Zhejiang University was established and incorporated into Zhu Kezhen College. The overall adjustment of the college was to be a science class, a mixed class and an experimental class of humanities and social sciences. Zhu Kezhen College has become an honorary college of Zhejiang University to implement "special training" for outstanding undergraduate students.

In 2011, the "Everest Plan" was included in the sub-plan of the National Youth Talents Development Plan, and was included in the scope of the talent work coordination group together with the "Ten Thousand Talents Plan" and the earlier "Thousand Talents Plan", which became an important part of the national talent strategy.

Talent plan led by the central coordination group for talent work

The industrial foundation laid by Qian Xuesen, the practical spirit of Shi Yigong, and the top-level design of the national strategy have gathered together at this moment, paving the way for the sea of stars in Chen Lijie.

Kai-fu Lee once recalled that when he founded Microsoft Research Asia in 1998, he hired the first batch of fresh graduates as researchers. "No one passed the test.". In 2011, JohnHopcroft, winner of Turing Prize, once commented on Yao Ban: "Yao Ban has the best undergraduate students and the best undergraduate education in the world." For this evaluation, Yao Qizhi confidently believes that it is well deserved.

Young people from ACM class and Yao Ban, and from "Everest Plan", stood at a new height and began to break through in the technical field.

Lin Chenxi, who completed her dream of winning the championship, became the teaching assistant of the first ACM class, and trained the next generation of champions in the ACM class. After graduation, she went to work in Microsoft Asia Research Institute and worked under Wang Jian, then the executive vice president. In 2008, they moved to Alibaba together, struggled in the arduous battle of cloud computing for four years, and completed Feitian’s large-scale cloud computing operating system.

Lin Chenxi, who "feels like a lifetime", founded Etu Technology with his high school classmate Leo Zhu in 12 years and started his business in the field of artificial intelligence. During the G20 period, the Ningbo Municipal Government arranged 10 cameras equipped with map-based capabilities in subway stations at key sections, and arrested 9 fugitives in three weeks.

Dai Wenyuan, who became a member of the first ACM class, inherited from Lin Chenxi, a senior, and won the second international ACM championship trophy in his junior year. Because I went out to participate in the competition, when I chose the research direction in my junior year, only the artificial intelligence direction that was "not hot at all" was left to choose. At that time, when artificial intelligence was unpopular, the tutor Professor Yang Qiang and Dai Wenyuan insisted on this direction.

In 2008, Dai Wenyuan realized the powerful contribution of data to artificial intelligence. In 2009, he gave up the opportunity to study PhD and joined Baidu. Together with Chen Yuqiang, who was an intern at that time, he built a commercial deep learning system-Baidu’s "Fengchao" advertising system. As a result, Baidu’s liquidity was improved by 800%, and Dai Wenyuan was promoted to be the youngest T10 scientist in Baidu. In 2015, Dai Wenyuan and Chen Yuqiang founded the fourth paradigm, hoping to make AI for Everyone in the stage of AI industrialization.

Lou Tiancheng, two grades younger than Dai Wenyuan, entered the first Yao Ban. During his school days, he toured all major competitions and lists at home and abroad, and was honored as the "building leader": the gold medal in the International Informatics Olympic Competition, the champion of the two-time Baidu Star Competition, the first TopCoder in China, the ACM international gold medal, and the champion of the Google Programming Challenge … He joined Google after graduating from Ph.D. in 2012, and later joined the Baidu unmanned vehicle team in Andrew Ng after a short stay in Quaro. At that time, Andrew Ng praised him on FB. In 2016, Lou Tiancheng, as a co-founder, founded Pony.ai, an artificial intelligence company, and helped a group of younger brothers and sisters in Yao Ban to cultivate unmanned driving.

Chen Shixi of Fudan, Lou Tiancheng’s old rival in the programming competition, is an anime fan, and later joined Baidu, where there is a saying that "the south is light and the north is natural". Chen Shixi left a set of machine learning infrastructure mio in Baidu, named after Qiu Shanling, the heroine of the famous cute cartoon "Girl with a Light Voice". mio later became the prototype recommended by companies such as Aauto Quicker, Didi and Meituan. In 17 years, Chen Shixi joined the driverless company Jingchi Automobile, and the same building leader continued to "compete between the North and the South" in driverless driving.

Yao Ban, who won the international ACM gold medal with Lou Tiancheng, devoted himself to academic research, and won the Sloan Prize for "Nobel Prize Vane" based on his research on nonconvex optimization in deep learning for 19 years. His achievements have an important influence on the theoretical research of artificial intelligence. Lou Tiancheng and Rong Rong’s third teammate, Hu Weidong, chose to work as an informatics teacher in the experimental middle school affiliated to Beijing Normal University after graduation, engaged in high school programming teaching, brought out the gold medal in the International Informatics Olympic Competition, brought out dozens of students who walked in Tsinghua, and became the "world gold medal coach" in informatics education, personally practicing the popularization of programming education in middle schools.

Tang Wenbin, the next younger brother of Lou Tiancheng, won the silver medal in the ACM International Competition. When he was in graduate school, his tutor went overseas for half a year and sent him to Microsoft Asia Research Institute for an internship. However, Yinqi, an undergraduate classmate, was making images in the next group of Asia Research Institute. The more they talked, the more they felt that images were the future direction. Robots must need a pair of eyes. In 2012, two people joined Yang Mu, a younger brother who is good at data mining, and founded Defiance Technology to "be the best face recognition cloud platform".

Tang Wenbin and Inch’s classmates Long Fan and Dr. MIT went to the University of Toronto, one of the holy places of artificial intelligence, to teach and study cryptography after graduation. At the end of 2017, at the invitation of Professor Yao Qizhi, he returned to Yao Ban to take a 3-hour cryptography course. In the class, Yao Ban, the classroom teaching assistant and Long Fan had a heated discussion on the expansion problems faced by the current blockchain. In mid-May 2018, this group published the results as a paper "Expanding the Satoshi Nakamoto Consensus to thousands of transactions per second" to explore how to solve the bottleneck of low throughput of public chains. Investment institutions blasted their contact information, and Long Fan and four companions expanded their thesis into the blockchain project Conflux. Four of these five people were born in Yao Ban.

China’s artificial intelligence startups have grown rapidly in the past three years, and six unicorns have appeared, with a total valuation of more than $12 billion. China recommended algorithms, autonomous driving and machine vision, and talents from ACM class and Yao Ban dominated the development of these tracks. What is worth pondering is that Yao Ban and the students in ACM’s class who went abroad to work in Google, Facebook and other overseas places were promoted quickly at the initial stage with their talent and accumulation, but they encountered "glass ceilings" one after another, and it was difficult to re-enter after being promoted to T6 level.

Our predecessors planted trees, while our descendants enjoyed the cool. Because of the excellent example of the predecessors, the subsequent students enjoy more and more resources and board a broader stage, and the top-level student exchange will produce a steady stream of students with top vision.

As Yao Ban Chen Lijie said: I feel extremely honored to be born in such a golden age. I dream that I can become a wave in the spring tide of the golden age and contribute to the wisdom of mankind. On the giant’s shoulder, he can make a declaration calmly:

"I’m Chen Lijie, and I want to be a theoretical computer scientist!"

Read the Apollo program first: how did the United States defeat the Soviet Union and realize the first moon landing?

        While carrying out manned space flight, korolev began its efforts to fly out of the earth. Of course, the moon closest to the earth is the first landing target for human beings to go into space. In order to land on the moon, at least three people need to take the same spaceship, so the size and weight of the spaceship are much larger than that of the Dongfang, which carried an astronaut before. In addition, the distance to land on the moon is much farther than that of orbiting the earth, so the thrust of the rocket must be much larger than that of the previous R-7. Korolev began to improve the R-7 in 1958. However, due to the political turmoil in the former Soviet Union, he was short of funds, and his work encountered many troubles. In 1959, Luna, the first spacecraft of the former Soviet Union to explore the moon, was supposed to touch the moon, but in the end it was 6,000 kilometers off the scheduled orbit. Fortunately, Lunar Exploration II was a success, becoming the first human aircraft to reach the moon, and korolev won the first place in the world for the former Soviet Union. The third ship went one step further. It sent back photos of the back of the moon.

Sergei korolev, the father of space flight in the former Soviet Union

        According to korolev’s plan, it is a matter of time before the Soviet Union landed on the moon, and it should be before the Americans. In order to meet the needs of landing on the moon, korolev put forward a new design scheme and long-term planning for a large rocket, which is the famous N1 launch vehicle of the former Soviet Union. N1 also has two little brothers N2 and N3, whose size and thrust are gradually reduced, and the latter is used to carry intercontinental missiles. However, just after the design scheme of N1 was released, before it was implemented, the former Soviet Union was caught in a debate about whether to give priority to the development of intercontinental missiles or manned rockets. In December, 1959, after intense discussions among officials in charge and experts at all levels, the idea of giving priority to missile development prevailed. In this case, there is no need to build a super-large rocket like N1. Although korolev has also obtained some funds to continue to develop rockets for landing on the moon, the former Soviet Union’s moon landing plan has temporarily stalled.

        At the same time, the White House ushered in a new owner, and the United States also entered their new era. The balance of the space race began to tilt in favor of the United States.

        On January 20, 1961, snow covered Washington, the capital of the United States. The youngest president in American history, only 43-year-old John F. Kennedy, was sworn in in front of the White House. A few months ago, he defeated Nixon, the then vice president, in the general election, and the two men always could not avoid a controversial topic-how to defeat the Soviet Union in the Cold War. American efforts began with President Eisenhower, and Nixon, then vice president, did a lot of work. However, the youthful Kennedy was much more ambitious than his predecessor. In Kennedy’s famous inaugural speech, he put exploring the mysteries of interstellar space as the first priority in his scientific work, before conquering deserts and treating diseases. And he called on the United States and the Soviet Union to join hands in these fields. Only four months later, Kennedy put forward an ambitious space program-landing on the moon within ten years. This program was named after the sun god, which is the famous Apollo Program.

        

Von Braun is with President Kennedy.

        The Apollo program is the largest plan for human beings to explore space and unknown areas, and the whole country in the United States has mobilized. Hundreds of universities, research institutions and companies, more than 20,000 scientists and 400,000 people directly and indirectly participated in this space program. The key to the Apollo program is the development of the rocket to the moon, and the popular candidate is von Braun. Therefore, when the project was about to begin, von Braun and his team transferred from the Army to NASA. Von Braun served as the director of Marshall Space Center, responsible for the development of rockets to the moon, the project code-named Saturn. Von Braun’s new job began in 1961, and he was fighting against his unknown opponent in the Soviet Union.

Von Braun, praised by NASA as the first person in the history of world space.

        Compared with korolev, von Braun is much luckier. The United States is more secure in financial resources and manpower than the former Soviet Union, so Americans catch up quickly. In 1961, von Braun’s Saturn I rocket was successfully developed, which was the first large thrust rocket made in the United States. The thrust of the first stage rocket reached 6670 kn, exceeding the thrust of all R-7 engines. Generally speaking, Saturn-1 was very successful. It not only successfully put five spacecraft, including command module and service module, into Earth orbit in 1964-1965, but also sent some satellites related to the Apollo program and microwave survey ships between the Earth and the Moon (to prepare for the subsequent communication on the moon) to the scheduled orbit.

The three astronauts of Apollo 11 reunited in front of the lunar module that year.

        NASA originally planned to use Saturn-1 to carry out four manned space flights in 1965-1966, but later it was found that the thrust of the rocket was slightly insufficient, so von Braun developed a Saturn-B rocket with stronger thrust in 1963. The thrust of its first-stage rocket was about 10% higher than that of Saturn-1, and the thrust of its second-stage rocket was more than doubled (890 kN to 400 kN). So far, the United States In addition to rocket technology, there are many cutting-edge technologies needed for landing on the moon. Let’s take a look at the preparations made by Americans on several key technologies.

        The first is the technology of landing and leaving the moon.It is not easy for astronauts to land on the moon safely. On the earth, with the help of the atmosphere and the ocean, we can slow down the capsule that is about to land by parachute, and we can also land on the ocean in order to prevent the capsule from colliding with the ground. Unlike the earth, the moon has neither atmosphere nor ocean, so these methods of landing on the earth are not used on the moon. The only way is to slow down the lunar module with a reverse rocket, just like what we saw in the movie Star Wars and various science fiction films. But in reality, it is very difficult to do so, and the rocket jet speed and angle must be controlled very well.

        Of course, astronauts are neither Chang ‘e nor WU GANG, so they can’t live on the moon for a long time, and they still need to leave the moon and return to Earth. At the beginning of the Apollo program, NASA proposed four return schemes.

        The first plan is to take a big rocket with the lander, and the United States is the smallest.

        The fourth scheme is to launch two rockets to the moon, one carrying the lunar module and the other carrying the rocket returning from the moon to the earth, and then assemble it on the moon. The disadvantage of this method is that if the trajectories of the two rockets deviate a little, the landing point of the lunar module and the returning rocket will be 180 kilometers or more, and the astronauts will not come back.

        Most experts prefer the first scheme because it is simple. At that time, most experts were not sure about air docking. In fact, von Braun also supports this scheme, and has planned to design a Nova rocket (nova) larger than Saturn V to accomplish this mission. However, a scientist named John Houbolt (1919-) insisted that the total weight of lunar landing equipment should be as light as possible, and tried his best to convince most people, so experts including the Marshall Space Center led by von Braun accepted the third scheme. The Apollo program finally adopted this scheme and achieved success. American historians believe that it would not have been possible to land on the moon in the late 1960s if NASA had not finally adopted the opinions of a few people, although Americans were able to land on the moon in the end.

        Of course, one of the difficulties of this plan is docking. For this reason, Apollo 9 conducted a docking test in orbit around the earth, and the test was successful. Only then did the Americans move on.

        Secondly, the technology of the moon landing spacecraft..Spacecraft landing on the moon include Command and Service Module (CSM) and Lunar Module (LM). As shown in the figure below:

The three parts of Apollo 11, from left to right, are the service module, the command module and the lunar module.

        The command module is the shelter for astronauts on their way back and forth. It is not only to send astronauts from the earth to the moon orbit, but also to return them, and it is also the only part that re-enters the atmosphere to send astronauts to the surface, so it has been tested the most in the Apollo program. This module is about three and a half meters in diameter, nearly four meters high and weighs 5.5 tons. The service module (SM) is connected with the command module (CM, sometimes called the space module in the news), and its diameter is similar to that of the command module, but its length is seven meters. It transports all kinds of materials needed for landing on the moon, including liquid fuel and various equipment, weighing 24 tons. The service module is connected to the command module and flies to the moon together, but it will be thrown away when the spacecraft re-enters the earth’s atmosphere. Most of the time, the service module and the command module are tested together. The part of landing on the moon includes the thrust rocket needed for landing on the moon and the rocket leaving the moon, as well as the lunar module. Although the weight of this part has been reduced as much as possible in the design, it still weighs 15 tons.

        Then there is the control technology.One of the most critical technologies is the Kalman filter in automatic control. This filtering method was invented by Rudolph E. Kalman (1930-), an American Hungarian mathematician. At the beginning of this control theory put forward by Kalman, its practicability was so doubtful that he did not publish this achievement in the journal of electronic engineering and automatic control, but published it in the journal of mathematics. One day in 1960, Kalman visited Stanley Schmidt (1944-), who worked in NASA, and found that his method was very useful for solving the difficult problem of orbit prediction in Apollo program, so he taught it to Schmidt.

        Finally, there is the problem of communication between the earth and the moon.The moon is 380 thousand kilometers away from our earth, nearly 10 times the circumference of the earth. Such long-distance two-way communication has never been carried out by humans before. Will the attenuation of the signal interrupt communication? In addition, it takes more than two seconds for radio waves to travel back and forth between the earth and the moon once. How to eliminate the influence of this delay on control? There are many problems that need to be tested one by one to determine. To this end, the United States launched some spacecraft to test the communication between the earth and the moon. Finally, Motorola provided intercom equipment between the moon and the earth. Unfortunately, this great company no longer exists independently today.

        In the race to the moon, the former Soviet Union was far behind the United States in key technologies except rocket technology.

        Of course, in the end, everything will go back to the rocket, because the total weight of several parts of the whole moon landing spacecraft exceeds 45 tons, which makes the manufacture of large thrust rockets become the bottleneck of the whole plan. Von Braun’s team needs to design a rocket with much larger thrust than Saturn-B. The previous dozens of various launch tests undoubtedly provided rich technical accumulation for their later development of new rockets. In 1967, von Braun’s masterpiece Saturn V was born.

        But in January 1967, Apollo 1 had an accident before it was launched. In a ground test, the oxygen cabin exploded and the spacecraft caught fire, killing all three astronauts. The accident did not shake the determination of Americans, but helped Americans find many problems and make a lot of improvements, from the design of spacecraft to the spacesuit. Some of these improvements benefited the later Apollo 13 and avoided new tragedies. Although the Apollo program was slightly delayed, in November, Apollo IV (to commemorate the three astronauts who died, Apollo 1, 2 and 3 were vacant) was successfully launched, which was the first test of Saturn V rocket. In the following six months, the United States conducted two more experiments and tested all the links needed for landing on the moon in an unmanned state. After half a year’s preparation, from October 1968, the United States began to use manned spacecraft (Apollo VII) for simulation experiments. In just seven months, the United States conducted as many as four experiments, and 12 astronauts went into space. Among them, Apollo 8 manned the lunar orbit for the first time, and three astronauts circled the moon for 10 times. Apollo 10 tested the landing process of the spacecraft to the moon and landed at a height of only 15,000 meters from the surface of the moon, which is only slightly higher than the cruising altitude of commercial aircraft.

        The next task is to land on the moon and let the astronauts set foot on the surface of the moon. For the first trip to the moon, NASA made full preparations. In the early stage, I launched many experiments and tried everything I could think of. The rest is to determine the candidate for the first moon landing mission. After many considerations, Neil A. Armstrong (1930-2012), Edwin E. Aldrin (1930-) and Michael Collins (1930-) were finally determined to perform this historic mission. Of course, to be on the safe side, NASA has also prepared a corresponding backup team. Even after selecting a three-person team, who will set foot on the moon first has become the focus of controversy among several astronauts. In training, Aldrin climbed out of the hatch first, and finally changed to Armstrong, because the design of the hatch was more convenient for him rather than Aldrin going out first. For the inside details of Apollo’s landing on the moon, readers can refer to the book Apollo-Lunar Expedition.

        Soon, a glorious moment in human history came. On July 16, 1969, at the Kennedy Space Center in Cape Canaveral, Florida, Armstrong and others boarded the towering Apollo 11 spacecraft and were about to begin the human journey to the moon. The Apollo landing on the moon was televised by the United States to the whole world, and Nixon, then president, watched the live event on TV from the Oval Office of the White House. I think that if every reader can go back to that day, he will definitely sit in front of the TV and watch it. Fortunately, more than 30 years later, in the command room of Kennedy Space Center, I saw the command of Apollo 11 mission and the video of landing on the moon at the simulation site.

        Ok, now please follow me to the command center. At 9: 32 am (Eastern Daylight Time), the rocket launch entered the final countdown. Astronauts and rockets are in good condition. Perhaps out of excitement or nervousness, Armstrong’s heart rate reached 110 beats per minute when the rocket was launched, which had never happened before. On the console, the display screens and lights of various instruments kept flashing, and the timer on the wall began to count down-10, 9, 8…3, 2, 1. At this time, the sound of "emission" sounded in the background. On the big screen, Saturn V ignited successfully, and the orange flame pushed the 110-meter-high behemoth to rise slowly and faster until the rocket disappeared on the screen. On the fourth day, July 19, the rocket entered the lunar orbit; On the fifth day, July 20th, Apollo 11 was ready to land on the moon. The camera switches to the image of Apollo 11 landing on the lunar surface, and there is a camera under the lunar module, which sends the blurred image of the lunar surface back to Earth. I saw the lunar module getting closer and closer to the surface of the moon and finally stopped there. This image can be seen on the website of NASA. After the lunar module landed safely on the surface of the moon, commander Armstrong returned the first words that humans said on the moon: "Houston, this is the Jinghai base. The eagle landed successfully. "

        Next, Armstrong and Aldrin should sleep for five hours according to the pre-set itinerary, because they didn’t sleep much during the flight. But both of them were so excited that no one could sleep. After consulting the headquarters, they set foot on the surface of the moon in advance. On the screen of the control room, Armstrong stepped down from the lunar module and set foot on the moon. His movements were very slow. Because of the long distance and the communication technology is far less developed than today, the images and sounds sent back are intermittent, but Armstrong’s famous words can still be distinguished, "This is one small step for man, but one giant step for mankind." The recording of these seconds can be heard on the Internet.

        

Aldrin is on the surface of the moon.

        More than 600 million viewers around the world watched the first human step on the moon on TV. Armstrong and Aldrin put some experimental instruments on the surface of the moon and collected more than 20 kilograms of lunar rock samples. The two of them stayed on the moon for about two and a half hours, and then went back to the lunar module to sleep. Although Aldrin accidentally broke the ignition switch of the return rocket, it was near miss. They turned on the switch with a pen, and the rocket sent them to the lunar orbit to rendezvous with the control/service module, and then returned to Earth. On July 24th, the command module carrying three astronauts fell into the Pacific Ocean. The whole process from launch to safe landing on the earth’s surface is about eight days and three hours.

        

Armstrong and other three astronauts spent more than ten days in the isolation cabin after returning from the moon. At that time, American President Nixon visited them in the isolation cabin at the first time and congratulated them through the glass window.

        The success of Apollo’s landing on the moon is a victory for all mankind. As many as 400,000 people directly and indirectly participated in the Apollo program (Nixon’s original words). They came from different countries in the world, including many Chinese scientists. How much contribution did von Braun make in the Apollo program? NASA commented on him like this: "There is no doubt that he is the greatest rocket scientist in history. His greatest achievement was that when he was the director of the Marshall Space Flight Center of NASA, he presided over the research and development of Saturn V and successfully achieved the great cause of human landing on the moon for the first time in July 1969. " It can be said that there would be no Saturn V without von Braun. Although humans can finally land on the moon, it will not be within the time limit set by Kennedy-the 1960s.

        On January 12th, 1966, korolev died of a surgical operation at the age of 59. It’s a pity that he didn’t see the successful docking of his designed spacecraft Soyuz and Salute-he had been buried underground for more than four years.

        Vasily Mishin (1917-2001), korolev’s successor, did not have the influence and courage of korolev. Although he completed the development of the N1 rocket under very difficult circumstances, the rocket failed in all directions. Coupled with the constant space accidents, especially the death of astronauts, the Soviet Union’s moon landing plan failed as a whole and was finally abandoned.

        In the end, Americans successfully landed on the moon many times, but the former Soviet Union did not once. The fundamental reason for this is not that korolev’s ability is not good, but that the former Soviet Union lost in its comprehensive national strength.

        Without his opponent, von Braun continues to devote himself to the space industry. After Apollo 11, the United States successfully landed on the moon five times, completing a feat in human history. In 1972, after achieving the expected goal, the United States terminated the Apollo program and developed a reusable space vehicle, the space shuttle. Five years after the last Apollo spacecraft landed on the moon, von Braun also came to the end of his life. In 1977, he died of cancer. Shortly before his death, he won the National Science Award, the highest award in American science and technology, but he was unable to go to the White House to receive the award.
