Lei Jiayin promotes electronic ticket checking, breaking the news of YOLO and Jia Ling.


1905 movie network news　On February 3rd, the actor appeared at the press conference as the promotion ambassador of "Jane Ticket Shadow Treasure", and together with Jane Ticket Group, he announced the official launch of the first interactive carnival of Spring Festival movies in China.


As the first interactive carnival of Spring Festival movies, the event will take the movie interactive cooperation platform, the simple ticket movie treasure applet as the carrier, and draw more audiences into the cinema with simple and fast interactive methods and rich movie viewing benefits, thus helping the Spring Festival movie market to flourish.


Talking about the original intention of being the promotion ambassador, Lei Jiayin said that the film industry has always been pursuing industrial development, and the all-round upgrade of the industry is not only inevitable, but also the form of electronic ticket checking can bring more convenient viewing experience to the audience. As one of the busiest actors in this year’s Spring Festival, he said that he has been paying close attention to the box office pre-sale performance of every movie during the period.


YOLO and Article 20, starring himself, were also sincerely recommended by Lei Jiayin at the press conference. The director didn’t show up after the official announcement in YOLO, which also made many viewers curious. Lei Jiayin said that he believes that after the film is released, Jia Ling will definitely bring great shock to the audience, and the content of the film will also make people cry and laugh at Qi Fei. Although Article 20 focuses on serious realistic themes, it also has full comedy elements. "The director has calculated that there are more jokes."


Zhang Guo, CEO of Simple Ticket Group, also introduced the event: "We firmly believe that electronic ticket checking will be the future development trend, and interactive movie will also become the standard for China film announcement." Zhang Guo also said that with this platform, the Group plans to make 2024 the "first year of film interaction in China", and normalize the interactive cooperation mode to cover other film schedules this year. At the same time, we will build a big data application scenario based on this, and continue to empower film producers, distributors, cinemas and cinemas and the general audience to jointly create a high-quality film industry development ecology.


It is reported that the carnival will start on the first day of February 10 and last until the fifteenth day of the first month of February 24. The audience can open and bind the simple ticket movie applet and scan the QR code on the front of the movie ticket to participate in the lucky draw.


From the first day of the Lunar New Year to the fifteenth day of the first month, the first 2,024 movie-watching users who have completed the redemption will distribute movie-watching surprise red envelopes, and they will also have the opportunity to receive new year benefits such as new electronic equipment, movie-watching gift packages and new energy vehicle awards.

The Japanese government, bent on discharging nuclear sewage, tried every means to appease its fishermen.

CCTV News:According to Japanese media reports on the 24th, according to relevant sources, the Japanese government and Tokyo Electric Power Company have decided to "discharge the nuclear polluted water from the Fukushima Daiichi nuclear power plant to the offshore through the submarine tunnel". It is said that the reason for adopting this discharge method is that it is easier for nuclear polluted water to spread in the ocean.

It is said that such discharge makes it easier for nuclear polluted water to spread in the ocean.

Affected by the earthquake and tsunami in 2011, the cores of Units 1-3 of the Fukushima Daiichi Nuclear Power Plant in Japan melted down. As of March this year, 1.25 million tons of nuclear polluted water has been produced in the nuclear power plant, including the water injected to cool these cores and the groundwater and rainwater continuously flowing in the surrounding areas, and it is still increasing.

In April this year, despite the strong opposition of the international community, the Japanese government still made a decision, saying that it would filter and dilute the nuclear polluted water and discharge it into the sea. It is said that the discharge will start in about two years, and it is expected to last for 20 to 30 years until the waste heap work is completed.

According to reports quoted by Japanese media on the 24th, the Japanese government and TEPCO have studied two schemes for discharging nuclear polluted water, one is to discharge it to the offshore about 1km away from the nuclear power plant through the subsea tunnel, and the other is to discharge it directly from the coast. According to relevant sources, the Japanese government and TEPCO have decided to adopt the scheme of "discharging to the offshore through the submarine tunnel", allegedly on the grounds that this discharge mode "makes it easier for nuclear polluted water to spread in the ocean".

The report also said that due to the need for stable underground rock strata for the construction of the subsea tunnel, TEPCO decided to start magnetic exploration of relevant seabed conditions in September, and then carry out drilling survey to confirm the geological structure. TEPCO will also submit an application for implementing the plan to the Japan Atomic Energy Regulatory Commission in September.

Ten years after nuclear polluted water enters the sea, it will affect the global waters.

In what way will radioactive substances affect the ocean by directly dumping nuclear polluted water into the sea?

The so-called nuclear polluted water refers to the cooling water continuously injected into the reactor to prevent the core from melting after the accident at Fukushima nuclear power plant. In addition, rainwater and groundwater will flow in automatically. At present, Fukushima nuclear facility will produce 140 tons of nuclear polluted water every day. Nuclear contaminated water containing radioactive substances will be sent to "multi-nuclide removal equipment" for purification. 62 kinds of radioactive substances such as cesium and strontium contained in nuclear waste water will be absorbed, but radioactive elements including tritium are difficult to be completely removed.

The German marine scientific research institute pointed out that the Fukushima coast has the strongest ocean current in the world. Within 57 days from the date of discharge, radioactive materials will spread to most parts of the Pacific Ocean, three years later, the United States and Canada will be affected by nuclear pollution, and 10 years later, it will spread to the global waters.

Japanese Fishermen: The position of resolute opposition has not changed.

The discharge of nuclear polluted water from Fukushima, Japan, is related to the safety of the global marine ecological environment and the lives and health of people in all countries. The international community generally expresses strong concern about the possible impact of this move by Japan, and fishery practitioners from all over Japan, led by Fukushima Prefecture, have also been strongly opposed.

The head of the Federation of Fishery Synergies in Fukushima Prefecture said on the 24th that the organization’s position of resolutely opposing the discharge of nuclear polluted water into the ocean has not changed. On the same day, the president of the Japan National Federation of Fishery Cooperatives also issued a statement saying that the organization had asked the Japanese government to "make a responsible explanation" on the scheme of discharging nuclear polluted water into the sea, but so far it has not received a specific reply.

The reputation of fishery is damaged. The Japanese government says it plans to spend money on seafood.

The Japanese government held a meeting on issues related to the discharge of nuclear polluted water into the sea on the 24th, and said that if the discharge of nuclear polluted water into the sea leads to the damage of Japan’s fishery image, the decline in demand for seafood, the decrease in sales and the decline in prices, the government will use state financial funds to purchase seafood.

According to the plan, once the sales of Japanese seafood at home and abroad drop significantly, the government will temporarily purchase and preserve frozen seafood through newly established funds, which will help expand the sales of unfrozen seafood.

[Enough science] What items can’t be put in the car in hot weather？

Summer strikes, and many places continue to have high temperatures. What items are stored in the car that may be dangerous? Some data show that when the outdoor temperature reaches about 30℃, the temperature of the dashboard of the vehicle under direct sunlight can reach 60℃ to 70℃. Therefore, some items, such as lighters, batteries, liquid perfume, sunscreen spray, etc., should not be placed in the car, otherwise accidents such as deflagration will occur at high temperature.

Strengthen the ideological and moral construction of the whole society

　　Author: Yu Huiying (Professor, Department of Marxism, Northeast Normal University)

　　Strengthening the ideological and moral construction of the whole society is an important way to improve the level of spiritual civilization of the whole society and form a good social fashion. The General Secretary of the Supreme Leader stressed that it is necessary to "inspire people to form good moral will and feelings, cultivate correct moral judgment and moral responsibility, and improve their moral practice ability, especially their conscious practice ability". This important exposition provides a fundamental basis for us to strengthen the ideological and moral construction of the whole society in the new era and new journey.

　　Stimulate people to form good moral will and emotion.

　　It is a systematic project to improve the ideological and moral level of the whole society and form a good moral fashion. It is an important task of moral construction to stimulate people to form good moral will and feelings and make all members of society realize the importance of morality to individuals and the whole society.

　　Morality is of fundamental significance to individuals and society, and the first thing to do is to respect morality and cultivate one’s morality. The harmony and stability of social life and the benign operation of social order need to be guaranteed by good legal norms and rule of law mechanisms. However, the experience of ancient and modern China and foreign countries shows that it is far from enough to rely solely on legal norms and the rule of law mechanism. General Secretary of the Supreme Leader emphasized: "Law is written morality, morality is inner law, and both law and morality have the functions of regulating social behavior and maintaining social order. To govern the country and society, we must pay attention to the rule of law and the rule of virtue, and attach importance to both the normative role of law and the educational role of morality, so as to realize that law and morality complement each other, and the rule of law and the rule of virtue complement each other. " In fact, the moral level of citizens determines a country’s social fashion, civilization and long-term stability. The strength of national development and the external image of the country are important cultural soft power of the country. Liang Qichao said: "The view of a country is more important to people, and it does not depend on the size of its territory or the size of its population, but on the character of its citizens." General Secretary of the Supreme Leader pointed out: "As long as the Chinese nation pursues a beautiful and lofty moral realm from generation to generation, our nation will always be full of hope."

　　To stimulate people to form good moral will and emotion, we should make people fully realize the importance of morality to the bright future of individuals, society and country and improve their consciousness of moral construction. Therefore, through education, guidance and encouragement, people, especially teenagers, should be clear about their personal behavior value orientation and code of conduct, and deeply realize that people’s behavior should not only be bound by law, but also conform to moral requirements and social and national interests. Therefore, in moral construction, we should vigorously preach the importance of morality to individuals, society and country, the important role of morality in the continuation of Chinese civilization, and the important role of moral construction in promoting Chinese modernization and realizing the great rejuvenation of the Chinese nation. As a result, all members of the society have a good moral will and feelings, and they are determined to be socialist practitioners who stress morality and value morality.

　　Cultivate correct moral judgment and moral responsibility

　　Cultivating correct moral judgment and moral responsibility and creating a strong atmosphere of respecting morality and doing good are important supports for ideological and moral construction. To strengthen the ideological and moral construction of the whole society, we must attach great importance to and do a good job in cultivating people’s correct moral judgment and enhancing people’s sense of moral responsibility, so that people can have a correct understanding and stand on various moral concepts and values, have the ability to pursue truth, goodness and beauty, and condemn falsehood, ugliness and ugliness, distinguish between socialist morality and feudal morality and capitalist morality, persist in cultivating and promoting socialist core values, and enhance their sense of responsibility in practicing socialist moral norms.

　　In promoting the new journey of Chinese modernization and strengthening the ideological and moral construction of the whole society, we must establish the correct moral judgment and moral responsibility of all the people. General Secretary of the Supreme Leader stressed: "Whether a nation or a person can grasp themselves depends largely on moral values. If our people can’t adhere to the moral values formed and developed on the land of our country and blindly become the echo of western moral values, then we really have to ask whether our country and nation will lose their spiritual independence. " Therefore, under the guidance of Marxism, our moral construction must cultivate correct moral judgment and moral responsibility that reflect the core values of socialism.

　　Core values are actually a kind of virtue, which is not only a personal virtue, but also a great virtue, that is, a national virtue and a social virtue. As the soul of contemporary Chinese’s values, socialist core values play a decisive role in forming the correct moral judgment and moral responsibility of the whole society. To cultivate people’s correct moral judgment and moral responsibility, we need to absorb valuable resources from Chinese excellent traditional culture and vigorously inherit and carry forward Chinese excellent traditional virtues. We should adopt an eclectic attitude towards the cultural and moral norms passed down by our ancestors on the basis of removing the coarse and selecting the fine, removing the false and retaining the true, adhere to the method of making the past serve the present and bringing forth the new, treat them discriminately and inherit them with sublation. "We should be good at using the philosophical thought, humanistic spirit and moral concept condensed in Chinese excellent traditional culture to distinguish right from wrong, distinguish good from evil, and know how to be honest and shameful", strive to realize the creative transformation and innovative development of Chinese traditional virtues, and educate and guide people to yearn for and pursue a moral, respectful and moral life.

　　Improve moral practice ability, especially conscious practice ability.

　　The ideological and moral construction of the whole society focuses on practice. To improve the ideological and moral level of the whole society and form a good moral trend of the whole society, we should pay attention to moral practice on the premise that all people form good moral will and feelings, and on the basis of having correct moral judgment and moral responsibility. Therefore, we must attach great importance to improving people’s moral practice ability, especially their conscious practice ability.

　　To improve people’s moral practice ability, especially their conscious practice ability, we should adhere to the unity of knowing and doing, actions speak louder than words, and work hard on detail, smallness and implementation. Pay attention to the daily, concrete, visual and life-oriented socialist core values, so that everyone can perceive it and understand it, internalize it into spiritual pursuit, externalize it into practical action, and achieve great morality, public morality and strict private morality. Persevere in improving people’s ideological and moral cultivation, consciously carry forward the spirit of patriotism and collectivism, guide people to learn from moral models, actively strive for goodness, and consciously abide by social morality, professional ethics and family virtues. Guide people to work hard, not covet comfort, not afraid of difficulties, not complaining about others, relying on hard work and sweat to open up their life and career prospects and pursue a better life.

　　Guide people to absorb beneficial nutrition from Chinese excellent traditional culture, nourish the soul and cultivate moral practice ability. Improve and perfect the social atmosphere that encourages people to carry out moral practice and consciously improve their moral practice ability. It is an important task for the ideological and moral construction of the whole society to create a social atmosphere of upward goodness. Vigorously publicize moral models and moral models, establish a reward and incentive mechanism to form moral models and moral models, and make them the leaders of good social customs.

　　Continue to promote the construction of institutional mechanisms conducive to the ideological and moral construction of the whole society. General Secretary of the Supreme Leader pointed out: "Cultivating and carrying forward socialist core values depends not only on ideological education and practice, but also on institutional mechanisms." People’s moral practice ability includes the ability to consciously practice morality, which requires both inner consciousness and external norms. We should use laws to promote the construction of socialist core values. All kinds of social management should shoulder the responsibility of advocating socialist core values, pay attention to embodying value orientation in daily management, and encourage behaviors that conform to core values and restrict behaviors that violate core values. By perfecting the system and mechanism in this respect, we will promote people to continuously improve their moral practice ability, especially their conscious practice ability, and guide people to strive to be practitioners and advanced in ideological and moral construction.

Parents with serious routinization of primary school students’ compositions should avoid these ＂misunderstandings＂ in education.

　　BEIJING, Nov. 6 (Ren Siyu) How to help primary school students write a good composition may be a headache for every parent. Instruct children to write about spring blossoms in spring, fruit fragrance in autumn, scenic spots when traveling, and housework when staying at home … … These topics seem to be "easy to write", but they are often not needed for a good composition. Seemingly simple composition, children often don’t know what to write and how to write it.

　　How should primary school students write a good composition? What educational misunderstandings should parents and teachers avoid? Recently, the writer Shang Ailan accepted an exclusive interview with Zhongxin. com. She has been teaching Chinese for 30 years. She told some "secrets" about composition with practical experience.

　　Avoid writing mom as a "domestic worker"

　　"My mother" and "I love my mother" can be said to be a topic that every child will write at school and parents are very concerned about, but many children will fall into a very familiar routine when they mention a pen:

　　In order to show "the brilliance of maternal love", children often write that their mothers are beautiful and capable, cooking, washing clothes and taking care of themselves when they are sick … … For example, "she leans towards my side with an umbrella and gets caught in the rain herself;" I didn’t study well, and she criticized me a lot. After the criticism, she touched my head and taught me kindly. I have a fever. She didn’t sleep a wink all night, and wrinkles have grown out. I must express my mother with good academic performance. "

　　However, according to Shang Ailan, who has been a Chinese teacher for many years, although the contact between mothers and children is mostly based on life, mothers are also people with independent personalities. She hopes that the image of mothers can be separated from the category of "domestic workers".

　　In the new book "Composition Class", she talked about an experience of tutoring primary school students to write a composition. In order to avoid "tragic" writing, she asked students to describe their mother’s occupation and what kind of characteristics they had, and encouraged children to tell stories between themselves and their mothers.

　　She believes that parents and teachers should realize that "as the first teacher of children, mothers must have abilities that children do not have, and they can teach by example." In this way, the image of mother in the composition can be changed from ‘ Domestic workers ’ It is also different from ‘ Mothers pay, children repay ’ The traditional thinking. Use ‘ Pay ’ And ‘ Gratitude ’ The family relationship maintained is by no means the original intention of my mother’s selfless dedication. "

　　After some guidance and narration, the children finally wrote an essay entitled "Mom Show Me Plum Blossoms", which was successfully published.

　　In Composition Class, Shang Ailan turned the primary school she had coached into three virtual images with different personalities: Wen Wen, Yi Yi and Ming Ming, and summed up her experience in composition education for many years by telling stories. All the conversations between teachers and students in the book are true records of the conversations in the teaching process.

　　Don’t be superstitious about the selection of excellent compositions.

　　Shang Ailan is a Chinese teacher who has been teaching for more than 30 years and a novel writer. In the autumn of 1999, the first online original literature competition was held under the banyan tree, with writers such as Wang Anyi, Jia Pingwa, Yu Hua, Acheng and Wang Shuo as judges, and Shang Ailan was the winner of the best novel award in this competition.

　　For a long time, she was better known as "the mother of writer Jiang Fangzhou". Jiang Fangzhou said, "When I read this book, I will recall my mother’s education from childhood, which I think can be confirmed. For example, when I was a child, she wouldn’t let me read the selected compositions of primary school students, which my mother also reflected in the book. "

　　Many parents think that the direct way to help children write their compositions is to give them model documents to read, but Shang Ailan said that most of the so-called excellent compositions are trained in a modular way. If conditions permit, she hopes that children can read more and better literary works.

　　There are also "gorgeous rhetoric" accumulated by almost everyone in childhood. "Beautiful words and sentences are not the only aesthetics of Chinese. Simplicity and humor are the beauty of language. "She believes that the most fundamental purpose of all methods is to make children happy to express in words." If you only advocate aesthetics, it will cause great fear to write a composition. "

　　She wrote in the composition class that many people want teachers to teach them more "writing skills", but in fact, finding "what to write" is the most important writing ability. When we find out what to write, the problem of how to write will be solved.

　　Jiang Fangzhou also expressed the same view: "When I was a child, I wanted to write something, whether it was interesting or not, but my mother thought it was interesting. If you have the creative impulse, you should write it down. As for whether it is beautiful or not, it is actually the second problem to be solved. Creative impulse is the most precious. "

　　Parents and teachers should not be judges, but servers.

　　In addition to composition selection and kind words and sentences, in the Composition Class, Shang Ailan also put forward different thoughts on many composition methods:

　　"Don’t use pinyin instead of Chinese characters!"

　　"For children, adults should not teach him to be afraid of words before teaching him nothing."

　　"Writing personal experiences well is more effective than any flowery rhetoric."

　　She categorically pointed out that some so-called "guidance" is not a method at all, such as: "To have a clear theme, to be vivid, to be concise and to the point, not to distinguish between primary and secondary, not to be anticlimactic, and not to be dull in language … … It’s like a doctor saying, "You should be healthy, be alive and kicking, have sound limbs, and don’t get stomach disease, heart disease, periodontitis or schizophrenia … …”

　　Jiang Fangzhou wrote, "My mother in life is very shy and hesitant, but my mother in this book is a firm and wise teacher, and she has an uncompromising determination about composition teaching." In an interview, Shang Ailan explained that this is due to the teacher’s "occupational disease". These experiences have been thought for many years and proved to be effective, so they will be very determined.

　　She found that many parents, while worrying about their children’s composition, often like to arrange some topics that they think are "easy to write" for their children, such as writing pencils, pencil cases, schoolbags, desk lamps, etc. "You don’t want to increase his pain index, you should be a server and provide him with as many life experiences as possible."

　　To guide children to write good compositions, Shang Ailan believes that the first is to help them mobilize their personal memories and stories from their own experiences; The second is to start reading and turn reading into personal experience; The third is imitation or reference, and the learned works will also become the source of some inspiration.

　　"If you have a unique personal experience and experience — — The theme itself is the greatest value of the work; Telling this experience honestly and seriously is the best writing style. "

　　In her view, the biggest misunderstanding in composition education is the orientation of parents and teachers: "We may regard us as the ‘ Judge ’ So of course, the child writes some fake big blanks. Do you think he likes it? He thinks you like it. " The most fundamental position of parents and teachers should be the service provider of children’s writing, assisting him, helping him and pushing him to write better things.

Looking at power consumption through inductance loss, the calculation is not complicated at all.

Address quoted in this article: https://www.eepw.com.cn/article/201706/346888.htm.

one, overview

The power consumption of power supply is various, including switching loss, input/output capacitance loss, static power consumption of controller and. This paper mainly introduces the simple calculation. Including two aspects: one is the loss related to the magnetic core, that is, the traditional iron loss; The second is the loss associated with the inductor winding, which is commonly called copper loss.

Total Power Dissipation（W）= CopperLoss + CoreLoss

CopperLoss = IRMS2*RDC(mΩ )/1000

CoreLossGenerally, it is obtained by checking the manufacturer’s form.

Photos of switching power supply on a motherboard

2, calculation method

Take Pulse’s PA1513NL series inductor as an example, and adopt PA1513NL.321NLT. The datasheet downloaded from official website is as follows. The basic parameters are: the inductance is 320nH, and the DC resistance is 0.53 11.3%.

In the design, we use this resistor in the switching frequency of 600kHz and the load current I.LOADIn the BUCK circuit of 30A, where iripple = 30% * i.LOAD.

According to the above formula, it can be easily calculated that the maximum copper loss is:

CopperLoss = IRMS2* RDC(mΩ )/1000 =（30A）2 *(0.53*111.3% mΩ ）/1000 = 0.531W

Regarding the maximum iron loss, we must first calculate △B: (because the inductance error is a curve, we use the normal value to calculate it).

△B = .23* L(nH)* △I = 0.23 * 320（nH）* 30% * ILOAD = 662.4

Since the switching power supply works at a frequency below 600KHz, the iron loss can be found to be about 0.18W by looking up the table.

Then the total loss is as follows:

Total Power Dissipation（W）= CopperLoss + CoreLoss = 0.711W

By looking up the table, we can get that the temperature rise of the inductor is about 45 degrees Celsius under normal working conditions.

The main functions of evaluating the loss of inductance are: first, to see whether the loss of inductance will cause the overheating of inductance, which will lead to the decrease or even damage of inductance value; The second function is to adjust the parameters of inductance and improve the efficiency of the whole power conversion system.

threeAbout CoreLoss

In fact, the calculation method and curve of CoreLoss are not given on the datasheet of many inductance companies. If so, it is almost impossible to calculate the iron loss. In this case, there are two suggestions.

If this inductor is used in high-current and critical equipment, then please choose a supplier that provides iron loss, such as Pulse, Wurth, JW Miller, etc.

If the current is relatively small or the switching frequency is relatively low, the general iron loss is not the key factor. Then first evaluate whether the copper loss is OK, and leave a certain margin. If the inductance is overheated in the subsequent test, try to reduce the switching frequency of the power supply, or adopt an inductance with a smaller DCR.

China is beautiful in summer under the lens of Tibetan villages, mountains, reservoirs and oases.

CCTV News:In midsummer, everything is rich. At the beginning of the program, we first follow the camera to feel the beauty of summer ecology.

What we are seeing now is Jiagenba Town, kangding city, Ganzi Prefecture, Sichuan Province, which is more than 3,200 meters above sea level. Here, Russian flowers are blooming for the second time. Russian tree, also known as begonia variabilis, grows in the plateau area of 3000-3500 meters. They are spread along roads, ridges, valleys and hillsides. Neatly arranged Russian flowers, highland barley with broken ground and Tibetan villages with red walls and white windows paint a unique pastoral picture of Tibetan villages.

Following the camera, we came to Dongling, Qinling Mountain, which is more than 2,900 meters above sea level in ningshan county, Ankang, Shaanxi. At present, it is the season when rhododendrons in alpine lobules compete to open. Rhododendron microphylla mainly grows in alpine grasslands at an altitude of 2,500 to 3,600 meters, 4-mdash per year; It blooms in June. It is also an important water conservation area of the Middle Route Project of South-to-North Water Transfer, and its unique geographical location and superior climatic conditions provide a good habitat for wildlife.

Now we come to Yatang Reservoir in Linxia Prefecture and Hezheng County, Gansu Province. From the air, the lake is like a jasper embedded in the mountains. Surrounded by clear water, mountains or strange peaks stand tall, or stone cliffs are stacked. The water in Yatang Reservoir is mainly spring water, rainwater and snowmelt water, with clear water quality and abundant water. In summer, the sun shines into the lake, and the lake presents this unique turquoise because of its depth, reflecting the verdant forests and grasses, the majestic mountains and the distant white clouds.

Now we come to Youyu County, Shuozhou, Shanxi. At present, the newly planted seedlings are being watered locally. In the early days of the founding of New China, the natural environment in Youyu County was very bad and the land desertification was serious. Over the past decades, the local government has persisted in planting trees, preventing wind and fixing sand, and the greening rate of trees in the county has increased from less than 0.3% to 57%, creating an ecological miracle of "desert" to "oasis". Youyu County has also become a comprehensive demonstration area for sand prevention and control, and the constantly optimized ecological environment has attracted a large number of tourists.

Be good at thinking strategically (thoroughly study and implement Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era).

　　Core reading

　　Formulating correct strategic strategies is a valuable experience for our party to move from victory to victory. On the new journey, we must adhere to strategic thinking, be good at looking at and thinking about problems strategically, look at the overall situation and seek a domain, grasp the situation and seek great things, and combine strategic firmness with strategic flexibility to better promote career development.

　　The strategic issue is the fundamental issue of a political party and a country. With accurate strategic judgment, scientific strategic planning and strategic initiative, the cause of the party and the people will be promising. General Secretary of the Supreme Leader stressed: "We are a big party, leading a big country, carrying out great undertakings, being good at strategic thinking, and being good at looking at and thinking about problems strategically." The Communist Party of China (CPC) has always attached great importance to strategic issues. Over the past century, our party has grasped the main contradictions and central tasks in different periods and formulated correct strategic strategies, thus overcoming numerous risk challenges and constantly moving from victory to victory. On the new journey, the party must always be in an invincible position, stand at the forefront of the times, closely follow the new historical characteristics, scientifically plan the overall situation, firmly grasp the strategic initiative, and unswervingly achieve strategic goals.

　　The Communist Party of China (CPC) attaches great importance to strategic issues.

　　Over the past century, one of the important reasons why our party has been able to advance with unity of thought, unity of pace and unity, and to achieve great victories and brilliant achievements in revolution, construction and reform, and to write the most magnificent epic in the history of the Chinese nation for thousands of years, is that our party adheres to the guidance of Marxism, is far-sighted and insightful, and not only solves practical problems, but also solves strategic problems, accurately judges and grasps the situation, and formulates realistic goals and tasks.

　　During the new democratic revolution, our party creatively put forward and implemented a series of correct policies and strategies. Our party deeply analyzed the social form and class situation in China, made clear the nature, object, task and motive force of the China revolution, put forward a two-step strategy of going to socialism through the new-democratic revolution, formulated the general line of the new-democratic revolution, opened up the revolutionary road of encircling cities with rural areas and finally winning national victory, timely solved the extremely complicated problems in the process of the China revolution, and guided the revolutionary ship of China to ride the wind and waves.

　　During the period of socialist revolution and construction, our party found the correct way to carry out socialist revolution and construction in China. After the founding of New China, the first generation of the central collective leadership of the Party with Comrade Mao Zedong at the core led the people, put forward the general line for the transitional period on the basis of quickly healing the wounds of war and restoring the national economy, creatively completed the transformation from the new democratic revolution to the socialist revolution, and made China, a big eastern country with a quarter of the world’s population, enter the socialist society. After the establishment of the basic socialist system, the strategic thought of building China into a powerful socialist country was formed. Our party adheres to an independent foreign policy of peace, advocates and adheres to the Five Principles of Peaceful Coexistence, and puts forward the strategy of dividing three worlds. Through a series of correct strategic strategies, socialist China has become a big country with important influence in the world.

　　In the new era of reform, opening up and socialist modernization, our party made a historic decision to shift the work center of the party and the state to economic construction and implement reform and opening up, and formulated a strategy of basically realizing socialist modernization in three steps by the middle of the 21st century. Scientifically judging the characteristics of the times and the international situation, putting forward that peace and development are the themes of today’s times, and adjusting various policies in time have created rare historical opportunities and a good external environment for reform, opening up and socialist modernization.

　　Socialism with Chinese characteristics has entered a new era. The CPC Central Committee with the Supreme Leader as the core has made overall plans for the great rejuvenation strategy of the Chinese nation and the great changes that have never happened in the world in a century. It is clear that it is necessary to adhere to the party’s basic theory, line and general plan, take overall care of great struggles, great projects, great undertakings and great dreams, and put forward to strengthen "four consciousnesses", strengthen "four self-confidences" and achieve "two maintenance", and put forward to make overall plans to promote the "five in one".

　　Our party is a big party, leading a big country and carrying out great undertakings. We should look at and think about problems more consciously from a strategic perspective, think about and grasp a series of major strategic issues facing the country’s development with a broader vision and a longer-term perspective, formulate the major policies, development strategies and policies of the party and the country with a firmer stand and a more scientific method, win the historical initiative in grasping the strategic initiative and realize historical changes in strategic planning.

　　Strategic thinking is the way of thinking that the Communist Party of China (CPC) people should establish.

　　Behind the scientific strategic drawing is superb strategic thinking. General Secretary of the Supreme Leader pointed out that strategic thinking "is always the way of thinking that the Communist Party of China (CPC) people should establish". Adhering to strategic thinking and being good at looking at and thinking about problems strategically means grasping the overall trend and direction of things and making judgments and decisions from the overall situation, long-term and general trend.

　　Only by taking the overall situation into consideration can we correctly handle the relations in all aspects and stages. It is an important aspect of strategic thinking to proceed from the overall situation and achieve the best overall and long-term results. Comrade Mao Zedong pointed out in "Strategic Issues in China Revolutionary War": "Strategic issues are things that study the laws of the overall situation of the war", and this is the truth. General Secretary of the Supreme Leader stressed that it is necessary to establish a sense of the overall situation, be good at looking at problems from the overall situation, look at the world, look at the future, look at the present and look at all aspects; We should be good at observing the general trend, seeking great things, and grasping the initiative in work; It is necessary to strengthen strategic thinking, enhance strategic determination, and achieve "let the wind and waves rise and sit on the fishing boat steadily." The key to the overall situation is to judge right and wrong and evaluate gains and losses from the overall situation, and not to put the cart before the horse and lose big because of small. For those things that are feasible from a local perspective, but not feasible from the overall situation, we must never do it; For those things that are not feasible from the local point of view, but feasible or even necessary from the overall situation, we must do it without hesitation. Always regard the overall situation as the starting point and the foothold of observing and handling problems, pursue the overall interests, and earnestly put the work of the region and the department into the international and domestic background and the overall work of the whole party and the whole country to think, study and grasp.

　　If you have a long-term mind, you will maintain your strength and stick to your principles when you do things. It is necessary to unify the present and the future, and focus on the future to seek the present. Handle the relationship between short-term goals and long-term goals, base on the present and focus on the long-term, not only insist on a protracted war strategically, but also fight a good battle of annihilation tactically. Strategically, we should persist in striving for progress in stability, do a good job in top-level design, grasp the rhythm and strength, and make contributions for a long time. Tactically, we should do practical things, pay attention to practical results, step by step, and fight one battle after another. Be good at thinking about the current problems in the process of development and positioning them in the long river of history, so that you can lift your weight easily and easily. Although some things are not effective at present, they can lay the foundation for the long term, so we must work hard to do them, but we must never do things like killing the goose that lays the golden eggs, fishing with exhausted resources, and quenching thirst by drinking poison.

　　Grasp the general trend to seize the opportunity. The General Secretary of the Supreme Leader pointed out: "Be good at observing the general trend and seeking great things, and think and study problems from the perspective of the two overall situations at home and abroad, the overall situation of the work of the party and the state, and the overall situation of comprehensively deepening reform." The general trend reflects historical inevitability. To grasp the general trend, we must be good at grasping the essence of things and the inherent law of development through complicated phenomena, and take precautions before they happen. It is necessary to unify seeking affairs with seeking potential, and seek great things based on the general trend. "when you take advantage of the situation, you can’t lose it." The situation is changing, the tasks are changing, and the work requirements are also changing. We must accurately recognize changes, respond scientifically, and take the initiative to change. Strengthen strategic planning, keep the overall situation in mind, grasp the general trend, focus on major events, make plans according to the situation, move according to the situation, and act according to the situation. They are good at accumulating the situation and gaining momentum, and they are also good at changing and adapting to changes, grasping the main aspects of major contradictions and contradictions, prioritizing, scientifically arranging troops, and firmly grasping the initiative in struggle.

　　Combine the firmness of strategy with the flexibility of strategy.

　　General Secretary of the Supreme Leader stressed: "The correct strategy needs the correct strategy to implement." Strategy leads strategy, which serves strategy under the guidance of strategy; Strategy to achieve strategy, the correct strategy needs the correct strategy to implement. To correctly handle the dialectical unity between strategy and strategy, we must organically combine the firmness of strategy with the flexibility of strategy.

　　Firm strategy is the foundation of success. General Secretary of the Supreme Leader pointed out: "In today’s world, opportunities and challenges coexist. The situation is changing, and what is most needed is strategic strength. " Once the strategic objectives, strategic compliance, strategic layout, strategic steps, etc. are established, we cannot waver and hesitate. To achieve great goals, make strategic choices, and make major decisions, we must have the enterprising spirit of "not being a hero until we reach the Great Wall" and the strategic determination of "flying around in chaos and staying calm". At present, the realization of the great rejuvenation of the Chinese nation has entered an irreversible historical process. We are closer, more confident and able to achieve the goal of the great rejuvenation of the Chinese nation than at any time in history. However, this goal can never be achieved easily with gongs and drums, nor can it be achieved overnight in a Ma Pingchuan. There are still various predictable and unpredictable risks and challenges on the road ahead. This requires us to maintain our strategic strength in the face of the complicated and ever-changing international situation and the arduous and arduous domestic reform, development and stability tasks, and persist in doing what we think is right in the right way, so as not to be blinded by flowers and clouds. History and reality fully show that the cause of the party and the people will be in an invincible position if we always maintain strategic determination, strategic self-confidence and strategic patience, make accurate strategic judgments, plan scientifically and win the initiative.

　　Policies and strategies should be realistic and effective. The specific policies and strategies formulated under the strategic guidance should be targeted and tailored to local conditions. "De" has changed, so has the direction and intensity of "Ya". Ask firewood in the mountains, ask fish in the water, and sing whatever songs you go to. Only by continuously enhancing the flexibility, coordination and matching of policy measures can the maximum policy effect be achieved. Policies and strategies should avoid simplification, persist in seeking truth from facts and proceed from reality. It not only insists on taking the overall situation and commanding the strategy with strategy, but also formulates supporting strategies closely around the strategic objectives, so that the strategies can closely connect with and strongly support the strategy; Not only focus on solving major problems to enhance the scientific and long-term guidance of strategic design, but also adjust the strategy in time according to the situation to ensure the effectiveness of the strategy; It not only focuses on formulating strategic vision and strategic planning in the long run, but also focuses on solving various contradictions faced by reform, development and stability, and enhances the pertinence, pragmatism and operability of strategic arrangements.

　　Firm but not rigid, flexible and principled. The firmness of strategy does not mean the rigidity of strategy. With the change of the overall economic and social situation and the evolution of the general trend of the times, timely strategic adjustment is the proper meaning of ensuring the scientific and effective strategy. Similarly, the flexibility of the strategy does not mean that the strategy is unstable. Stand high and do things realistically. We should not only focus on the direction, grasp the major events and seek the long-term, but also grasp the starting point and focus of the work. It is necessary to calculate both the general ledger of large accounts and the detailed accounts of small accounts. Be good at using reform thinking and methods, and make overall consideration of short-term response and medium-and long-term development. We should not only strategically lay out the situation, but also make good decisions at key points. Consciously align with the party’s theory, line, principles and policies, calibrate deviations in time, implement the strategic decisions made by the Party Central Committee to the letter, implement the decision-making arrangements of the Party Central Committee in a down-to-earth manner, seize the opportunity, make a difference, constantly promote the development of the party and the country, and create new brilliant achievements.
