Just look at the flow and ignore the musical evaluation. The annual golden song is accused of putting on a show.

Fox Xia and Yisa sang "Do you know?" on the list.

  A Song of Acacia (Half Sun), Green (Chen Xuening), quiet inside (Ice Paper), The Rest of My Life (Ma Liang Sun Qianru), Do You Know (Fox Xia, Yisa), Waiting for the Next One (Ti mo Feng), Like a Fish (Wang Erlang), One Million

  This is the "Top Ten Golden Melody Awards of the Year" recently announced by a music platform — — Jay Chou, Faye Wong, Xu Wei, Mayday and others’ new songs were not included in the list, and more were so-called online celebrity’s works. As soon as the list was published, it immediately triggered a question from netizens: Except "Do you know whether it is known or not" with the popularity and popularity of Zhao Liying’s TV series, I haven’t heard many other songs. Am I old?

  Awards speak to fans with data.

  According to Tencent, the organizer, the award relies on the platform’s massive users and huge data to "let more diverse data and fans speak". The list was selected on the basis of platform users and huge data, comprehensively considering the time dimension, list results, market value and other factors. It is hoped that by creating a series of leading, authoritative and fair awards, new outstanding works will be continuously explored, and a better platform will be provided for many musicians to further stimulate their creative desire and stimulate them.

  However, this list of golden songs selected according to traffic and fans has aroused doubts from netizens — — Because these so-called golden songs, many people have never heard of them. Some netizens questioned: Can the "golden songs" selected by traffic be handed down? How can the Chinese music scene supported by traffic develop and advance?

  Some netizens questioned how this list was released. "Most singers don’t know it; Jay Chou, Faye Wong and Ronghao Li have all released new songs, and it is really unacceptable that they are not on the list. " "The Wolf Disco is better than these on the list!" Some netizens said with emotion.

  Music critic

  The top ten hits are a show.

  Guo Zhikai, a well-known music critic, said in an interview with Beijing Youth Daily that the top singers in Chinese music, such as Jay Chou, Mayday and Xu Wei, have released new songs this year. Young musicians such as Ronghao Li and Mao Nan also have new works. Now, in this so-called Top Ten Golden Melody Award, none of the works of the above singers are on the list, and the songs on the list make people feel puzzled and too casual after reading them. It can be seen that this list has little to do with music.

  Guo Zhikai believes that taking traffic as the standard, it pays too much attention to commercialization and ignores musicality. It can’t be called an award, but it can only be called a show. How can it be leading, authoritative and even fair? The spread of this trend will only attract more musicians who are eager for quick success and instant benefit to create so-called "flow works" opportunistically. Guo Zhikai said, "The flow is dominant and the originality is neglected, which will not help the development of Chinese music."

  Li Guangping, a famous musician, told the reporter of Beiqing Daily that he had only heard "The rest of my life in the future" on the list, and the evaluation was "not bad". "Others didn’t listen, maybe it was a really popular song this year, but it is not certain whether it can be circulated." Li Guangping said that the most direct consequence of choosing songs based on traffic is that a number of popular songs may be created specifically for traffic. Taking the flow as the standard will also obscure some excellent works, or ignore the musicians’ new exploration and aesthetics, and may even drown out those musicians who insist on guiding the audience’s taste with their own aesthetic value.

  insider

  The music platform cannot cater to it blindly.

  In the past, the announcement of new songs mainly relied on traditional media such as radio and television, and the audience passively accepted fixed information. With the development of the Internet, various music platforms have been born, and gradually become the main position for the audience to obtain music.

  According to the reporter of Beiqing Daily, at present, most music platforms will push data to users according to the amount of songs played, the amount of collections and the singer’s social media activity index. The insiders believe that the music platform not only has the function of bringing different types of music together, but also should shoulder the mission of guiding the public’s literary appreciation. It should not only be based on traffic, but also cater to it blindly.

  Li Guangping, a musician, believes that flow is king, which is only a transformation of business model. Really good works will always be appreciated by people, and all kinds of music styles will grow freely. This is a healthy music scene.

  He said that compared with the flow, he pays more attention to copyright and how music creators get feedback. For example, every song on the line can be authorized by songwriters or record companies, so that there is no place for cover songs and songs suspected of plagiarism. "Now, for an excellent work, there may be ten works imitating plagiarism, which is very bad and we must put an end to it." (Text/Beijing Youth Daily reporter Shou Pengzhen Coordinator/Liu Jianghua)

How to deal with the new mutant strain Omicron? Expert: Vaccination is still an effective means.

  People’s Daily Online, Beijing, 1 December (James Zhou Ding Yixin, intern Liu Mingxi) The World Health Organization recently convened a special evaluation meeting for the Omicron strain of COVID-19 mutant virus that appeared in some countries recently, and listed it as a "mutant strain that needs attention", asking countries to strengthen monitoring and sequencing.

  Why does Omicron "need attention"?

  On November 27th, local time, the research team of Rome Children’s Hospital released the first picture of Omicron strain. The picture shows that compared with the 15 mutations of Delta strain, Omicron strain has more than 30 spike protein mutations on its surface, which are diverse and most of them are located in the interaction area with human cells.

  "The Omicron strain carries a large number of mutations and spreads quickly." Xu Ke, a professor at the State Key Laboratory of Virology of Wuhan University, told the reporter of People’s Daily Online’s "Strong Observation" column that the new strain is the first time to combine some mutations in other strains. Some data show that the new strain may have caused as many as 90% of new cases in gauteng province, South Africa, and it has spread all over South Africa, which shows that Omicron has certain infection advantages compared with other strains.

  What does this virus mutation mean?

  "Although there are superimposed mutations, whether the new mutant has stronger infectivity and transmission ability needs further experimental research." Xu Ke said that the amino acid polarity of the new mutant was different in the superimposed mutation, so the previous research conclusions could not be directly applied.

  In order to prevent the spread of COVID-19 mutant virus Omicron strain, the United States, Britain, Israel, Japan and other countries and regions have tightened their entry policies and upgraded their prevention and control measures. Should China also adjust its immigration and segregation policies? How should ordinary people respond?

  China CDC responded to the hot issue of Omicron mutant on the 29th. The genome analysis of the mutant showed that its mutation site did not affect the sensitivity and specificity of mainstream nucleic acid detection reagents in China. The Institute of Virology of China CDC has established a specific nucleic acid detection method for Omicron mutant, and continuously carried out virus genome monitoring for possible imported cases.

  According to WHO statistics, as of November 30th, local time, Omicron strain had appeared in 19 countries and regions, but this strain accounted for less than 0.1% of the 839,119 virus gene sequence samples collected in the past 60 days, with only 159 samples. Delta is still the main epidemic strain in the world.

  "Although the Omicron strain carries a lot of mutations, it is still Covid-19." Xu Ke reminded the public that there is no need to panic excessively. As long as the epidemic prevention policy is strictly implemented and personal protection is done, Omicron strains can still be effectively prevented and controlled.

  Does the existing vaccine still work?

  "All the vaccines that have been approved can greatly reduce the severe disease rate and mortality caused by mutant strains, and vaccination is still an effective means to deal with Omicron." Xu Ke said that vaccination makes our body produce neutralizing antibodies, which are "precision guided missiles" against foreign invaders. Even though there are many mutations in Omicron, the basic function of mediating virus invasion remains unchanged, and some of these antibodies can always act on Covid-19 of different mutant strains.

  Before the press release, the reporter was concerned that many vaccine companies in China were paying close attention to the mutant strain, and some of them had started the research and development of new vaccines.

Honeysuckle decoction can fight swine influenza virus.

  On October 7th, Zhang Chenyu, Dean of School of Life Sciences of Nanjing University, published an article in the top international academic journal Cell Research, revealing that a plant microRNA (MIR2911) directly targets influenza A virus, including H1N1,H5N1 and H7N9. Honeysuckle is rich in this kind of microRNA. After ingesting honeysuckle decoction, mice can reduce the mortality rate of various influenza viruses including H5N1 and prevent them from being infected with influenza A virus.

  Zhang Chenyu introduced that plant microRNA is a kind of noncoding RNA with a length of about 19-24 nucleotides. In previous studies, the team has confirmed that those plant microRNA stably existing in mammalian serum and plasma are actively secreted by tissues and cells, which can be used as new biomarkers of diseases and play the role of intracellular molecular signal transmission.

  The project team found that MIR2911 can be selectively enriched in honeysuckle decoction, and after drinking honeysuckle decoction, MIR2911 can be delivered into plasma and lung tissue. They also confirmed that MIR2911 can inhibit a variety of influenza viruses by targeting two genes, Pb2 and NS1, which are essential for influenza virus replication. Moreover, both synthetic MIR2911 and endogenous MIR2911 in honeysuckle decoction can effectively protect animals from H1N1 infection, and this protection depends on the binding site of MIR2911 on PB2 or NS1 gene. MIR2911 can also effectively inhibit the replication of influenza viruses H5N1 and H7N9, which indicates that it has broad-spectrum anti-H1N1 effect.

Han Changfu, Minister of Agriculture and Rural Affairs: Opening a New Journey for the Development of Agriculture, Countryside and Farmers

  Whether agriculture is strong or not, whether the countryside is beautiful or not, and whether farmers are rich or not determine the quality of a well-off society in an all-round way. The 19th National Congress of the Communist Party of China proposed to implement the rural revitalization strategy. When the General Secretary of the Supreme Leader attended the deliberation in the Shandong delegation during the two sessions, he delivered an important speech on the implementation of the rural revitalization strategy, emphasizing the need to implement the rural revitalization strategy in a down-to-earth manner. Implementing the rural revitalization strategy is the general starting point for doing a good job in "agriculture, countryside and farmers" in the new era. Han Changfu, Minister of Agriculture and Rural Affairs, said in an interview that the rural revitalization strategy conforms to the phased changes in urban-rural relations and follows the laws of agricultural and rural modernization. It is a major strategic deployment that is related to the overall situation, fundamental and long-term, and has opened a new era of "agriculture, rural areas and farmers". With greater determination, clearer goals and more powerful measures, we should promote the all-round upgrading of agriculture, the all-round progress of rural areas and the all-round development of farmers, take the road of rural revitalization in Socialism with Chinese characteristics, make agriculture a promising industry, make farmers an attractive profession, and make rural areas a beautiful homeland that lives and works in peace.

  Investing in real money and relying on hard work to promote the comprehensive revitalization of the countryside.

  At the Central Rural Work Conference, General Secretary of the Supreme Leader mentioned the "seven ways" of rural revitalization in Socialism with Chinese characteristics, and in the Shandong delegation, he also talked about promoting the "five revitalization" of rural industries, talents, culture, ecology and organization, which is the direction, focus and overall deployment of rural revitalization strategy.

  Han Changfu said that there is a lot of work to be done to implement the rural revitalization strategy. To sum up, we should grasp the "three major issues". The first is to make major plans. According to the requirements of "five in one", we should plan from the aspects of industrial development, rural layout, land use, infrastructure and public services, draw a blueprint and stick to it to the end. The second is to introduce major policies. It is necessary to study and introduce relevant policies, promote institutional innovation, and enhance the vitality of rural development. The third is to implement major actions. Rural revitalization requires real money and money, as well as real knives and guns. It is necessary to adhere to the problem orientation, adhere to the shortcomings, plan and implement the three-year action of rural human settlements improvement, the action of revitalizing villages and strengthening counties through industry, and lay a solid foundation for three years of precision poverty alleviation.

  Among the "five revitalization" emphasized by the Supreme Leader General Secretary, the first revitalization is the revitalization of rural industries. Industrial prosperity is the focus of rural revitalization. It is necessary to improve the quality, efficiency and competitiveness of agriculture and increase farmers’ income by developing modern agriculture. First, we should further adjust and optimize the agricultural structure, promote the integrated development of primary, secondary and tertiary industries in agriculture, solve the problem of farmers’ transfer of employment and extend the industrial chain of agriculture. Second, it is necessary to promote quality to promote agriculture and green development, and realize the coordination and unity of ensuring supply, income and ecology. Third, we should expand the function of agriculture, link agriculture with rural society, culture and farming civilization, and also link urban and rural areas.

  It is necessary to achieve rapid development, transformation and upgrading of agriculture through industrial revitalization and promote all-round progress in rural ecological environment, rural civilization and social governance under the general pattern of rural revitalization.

  Respect the dominant position of farmers, and constantly improve the sense of acquisition, happiness and security of hundreds of millions of farmers.

  Farmers are the main body to implement the rural revitalization strategy, and to promote rural revitalization, we must rely on farmers for the sake of farmers. This is one of the basic principles defined in the No.1 Document of the Central Committee.

  Han Changfu said that on the one hand, we should give full consideration to the interests of farmers while adhering to their dominant position. It is necessary to take promoting farmers’ overall well-off and common prosperity as the starting point and the end result, so that hundreds of millions of farmers can share the fruits of reform and development.

  On the other hand, farmers should be actively involved in rural construction. We should respect the initiative of farmers and give full play to their creative spirit. Now all kinds of investors come to participate in agricultural and rural construction, including industrial and commercial enterprises, migrant workers, college students, scientific and technological personnel, etc. We encourage and welcome them, but we must not forget that farmers are the most important subjects, and we must mobilize their enthusiasm, initiative and creativity. The government should help plan, guide and support what to do and how to do rural revitalization, but it can’t replace farmers’ decision-making, let alone engage in coercive orders against their wishes.

  The situation in rural areas of China is very different, and the basis of development varies from place to place. To implement the rural revitalization strategy, we should proceed from the rural reality, have historical patience, scientific planning, precise policy, pay attention to quality, follow the laws of rural development, and make urban and rural areas different and beautiful.

  Promote the solution of the problems of good people, land and money, and implement the priority development of agriculture and rural areas.

  When deploying and implementing the rural revitalization strategy, the 19th National Congress emphasized that priority should be given to the development of agriculture and rural areas. How to implement the priority development of agriculture and rural areas? The key is to implement institutional arrangements.

  Han Changfu said that the implementation of the rural revitalization strategy should implement the "four priorities", that is, giving priority to cadre allocation, giving priority to factor allocation, giving priority to capital investment, and giving priority to public services. It is necessary to strengthen research in these aspects, which should be reflected in institutional mechanisms and specific policies. To implement the rural revitalization strategy, a large number of modern resource elements need to be put into agricultural and rural construction, and the key is to solve the three problems of "people, land and money".

  Focusing on solving the problem of "people", we should cultivate and attract talents from all walks of life to participate in rural construction. It is necessary to cultivate new professional farmers and expand the main body of new agricultural management; Grasp "attracting talents to attract phoenix" and attract all kinds of talents to start businesses and innovate in rural areas.

  Focus on solving the problem of "land" and strengthen the institutional supply of rural revitalization. It is necessary to innovate the land income distribution mechanism and solve the dilemma of "rural land can’t be used and used badly". The contracted land should keep the land contract relationship stable and unchanged for a long time, and implement the "separation of powers"; Homestead should explore relevant policies, revitalize idle farmhouses and homesteads, take the road of "separation of three powers", and moderately release the right to use on the basis of insisting that the ownership of homesteads belongs to farmers’ collectives and the qualification belongs to members of collective economic organizations; Collective construction land should explore direct access to the market to achieve the same land, the same rights and the same price.

  Focus on solving the problem of "money" and strengthen investment support. Public finance should be tilted towards "agriculture, rural areas and farmers", gradually solve the problems of infrastructure, public services and other debts, and accelerate the filling of shortcomings in the field of poverty alleviation.

  Han Changfu said that in recent years, private capital investment in rural areas has grown rapidly. For industrial and commercial capital to go to the countryside, we should encourage and welcome it, optimize the environment, protect its enthusiasm, and at the same time strengthen guidance and regulation.

Does fake medicine have an effect on treating diseases? The amazing secret of the "secret recipe of the family"

  Cctv newsRecently, Chongqing police cracked a large counterfeit drug case involving more than 10 million yuan. The police investigation found that a miraculous medicine, which claims to be made up of dozens of traditional Chinese medicines and can cure all kinds of diseases, is sold in the rural market of Chongqing. This so-called panacea can not only cure diseases, but also bring multiple injuries to patients after long-term use.

  Ms. He from Pengshui County, Chongqing added a teacher who claimed to be surnamed Zhou through WeChat. This teacher Zhou recommended an ancestral Chinese medicine called "Fengshi Tougu Dan". Teacher Zhou vowed to assure Ms. He that as long as she took this medicine, she could cure any illness.

  Ms. He bought nearly 1,000 yuan of "Fengshi Tougu Dan" for her grandmother with rheumatism. However, not long after receiving the goods, Ms. He found the problem. The medicine was not only poorly packaged, but also had unsatisfactory curative effect.

  Ms. He suspected that the medicine was fake, and then she went to report it. After receiving the report, Pengshui County Food and Drug Administration Branch, together with the county public security bureau, sent these "Fengshi Tougu Dan" to the relevant departments for testing. After being identified by Chongqing Food and Drug Administration, this product was counterfeit.

  The police investigation found that the drug was not only sold in Pengshui County, but also sold everywhere in the surrounding rural markets. The Anti-Counterfeiting Corps of Chongqing Public Security Bureau immediately set up a task force to explore and arrange, and gradually sorted out a criminal network headed by Liu and Xu, which produced and sold counterfeit drugs in Guizhou, Sichuan, Hunan, Shaanxi, Chongqing and other provinces and cities. Soon, the police were divided into four roads to arrest Liu, Xu Moumou and others.

  After arresting four major suspects, including Liu and Xu, the police seized three production dens and more than 10 sets of production equipment, and seized more than 10,000 counterfeit medicines "Fengshi Tougu Dan" and more than 100 kilograms of raw materials.

  To the police’s surprise, the producers of these counterfeit drugs, Liu and Xu, are a rural couple with only primary school education in Dafang County, Guizhou Province, and their families have no medical experience, not to mention the so-called Chinese medicine family. The dens that produce fake drugs are also these messy houses. It is in this kind of production dens that Liu and Xu and his wife made their own recipes and made fake drugs Fengshi Tougu Dan, which were sold to five surrounding provinces and cities.

  "Ancestral secret recipe" is actually patched up by counterfeiters online.

  During the process of handling the case, some people reported to the police handling the case that these fake drugs seem to be really effective. Some patients have relieved their pain symptoms when they first took these drugs. Are these "Fengshi Tougu Dan" really effective?

  When Liu and Xu promoted their fake medicines, they all used the banner of "Xu Shi’s secret recipe", claiming that their "Fengshi Tougu Dan" was made up of dozens of precious Chinese herbal medicines. The police investigation found that the so-called "Xu Shi’s secret recipe" formula was completely patched together by Liu and Xu through online search.

  Counterfeiters add prescription drugs to counterfeit drugs. 

  A patchwork formula is a shoddy fake medicine, but some patients report that they have a certain effect after taking these drugs, especially in the first few days of taking them. Then what is the reason? The police sent these drugs to the drug supervision department for identification and found that the reason was that a large number of prescription drugs with analgesic and anti-inflammatory functions were added to the drugs.

  In these formulas, Liu and Xu have not only added prescription drugs with analgesic and anti-inflammatory functions, but also added hormones, which will not only make patients dependent, but also bring multiple injuries to patients with rheumatism.

  Selling the rural market makes a profit of over one million a year.

  According to the producers of counterfeit drugs, Liu and Xu, the main sales market of counterfeit drugs produced by themselves is in rural areas. These simply packaged drugs sell very well after playing the banner of ancestral secret recipes.

  The police investigation found that Liu and his wife did not sell these drugs directly to the countryside, but first sold these counterfeit drugs to the next homes in Guizhou, Sichuan, Hunan, Shaanxi, Chongqing and other provinces and cities at low prices through logistics express delivery and WeChat collection, and then these next homes increased their prices layer by layer, and finally sold them in rural markets by setting up stalls.

  These counterfeit drugs cost more than 20 cents a pill from the factory, and the price of each pill has soared tenfold when they reach the patients. Because the villagers living in remote villages lack the common sense of drug use, even if they are skeptical about this fake medicine with the secret recipe of their ancestors, most of them will not judge whether it is true or false through formal channels, but buy medicine by personal feelings.

  Due to the addition of analgesic and anti-inflammatory drugs and hormones to counterfeit drugs, some patients mistakenly think that these counterfeit drugs have real effects, and then through the mode of word of mouth, more relatives and friends come to buy these counterfeit drugs. It is precisely because of this deception that Liu and his wife earned a lot of illegal benefits in just one year.

  Chongqing police said that they will further carry out clue verification, case investigation and centralized network collection in response to the crime of producing and selling counterfeit drugs.

After a long absence, the big screen is finally back!

  On July 16th, China Film Bureau issued a notice that cinemas in low-risk areas can resume opening in an orderly manner on July 20th, provided that all epidemic prevention measures are effectively put in place, while cinemas in medium and high-risk areas are temporarily closed. After the news came out, China fans immediately enthusiastically supported the resumption of cinema with practical actions, and pressed the "accelerate" button for the resumption of China’s film industry: on the first day of the resumption of cinema on July 20, the total box office of the national movies reached 3.5 million yuan, which is still growing in recent days. As of 19: 00 on July 23, the national cumulative box office has exceeded 18.85 million yuan. In addition to China, French, British, Singaporean, Malaysian and other countries have successively joined the "cinema resumption tide". Cinemas in various countries have taken a series of special prevention and control measures to ensure the safety of customers: Britain and France readjusted their cinema seating plans to ensure a safe social distance between audiences, and even dispatched the popular "Minions" to accompany you to the movies; South Korea’s CGV company has introduced a new "contactless cinema" model to reduce risks. During the epidemic period, in order to minimize the risk, various ways of watching movies have emerged: Wal-Mart will transform the parking lot into a drive-in cinema on a large scale, and "floating cinemas" have also emerged in Australia and the United States. You can also enjoy movies by boat on the Seine River. How beautiful it is.However, after 178 days of separation, we need to restart the agreement with cinemas step by step. The experience of returning to work and epidemic prevention measures of cinemas in various countries may help us to abide by various epidemic prevention requirements with awe and cherish this rare reunion time.

  site

  Cinemas around the world welcome to return to work.

  The French is happy to buy old movies.

  Singapore’s movie experience is reassuring.

  The attendance rate of Malaysian cinemas is less than one third.

  With the epidemic situation stabilizing and all walks of life gradually returning to work, cinemas in many countries around the world that have been closed for several months have finally welcomed the first audience.

  On May 28th, local time, French Prime Minister Edward Philippe announced in a live TV broadcast that cinemas will reopen all over France on June 22nd. Since mid-March, in order to curb the spread of Covid-19, French cinemas have been closed, but now they can finally open again. In an interview with French 24 Hours, the cinema manager Louis Meyer said, "No words can express my feelings now. We have been waiting for 99 days."

  Although the cinema has reopened, it is unlikely to return to the state before the epidemic immediately. Because Hollywood and other production companies have postponed the release date of important films, there are no new films to be released in the cinema at first, so the audience will have to accept films with old themes like De Gaulle. Charles de Gaulle is a biographical film about French wartime leaders. During the epidemic, the release was interrupted because of the blockade of cinemas. However, Lisa Nesselson, the cultural editor of 24 Hours in France, thinks that this situation will not dampen the French’s enthusiasm for going to the cinema. On June 22nd, she said: "France can be said to have a real advantage in the reopening of cinemas around the world, because 40% of the 6,000 projection rooms in France are from art galleries, which means that the French is very willing to buy old movies."

  France is one of the countries that love movies most in the world. According to a previous poll, 18.7 million people plan to go to the movies after the cinemas return to work, which accounts for almost one third of the total population of France.

  In addition to France, on June 3rd, Singapore Information and Communication Media Development Board also announced that cinemas in Singapore could reopen on July 13th, but cinemas must take necessary preventive measures to control risks related to novel coronavirus. These measures include: readjusting the seats in cinemas, ensuring a safe distance of at least one meter between customers, allowing family members or friends in the same industry to sit together but not more than five people, controlling the number of people in each screening hall to be less than 50, and taking measures such as distancing themselves from queues and other crowd management.

  Although most Singaporeans think that the protection measures for cinemas are very thorough, some people have made other preparations for safety. In an interview with Singapore’s Today newspaper, Ms. Wang said that she would avoid eating in order not to take off her mask. Mr. Kong, the designer, said in an interview that he would choose to go to the cinema on weekdays to avoid the crowd. Another movie lover, Ben Soh, agrees with this view and says that he would prefer to watch movies on weekdays because it is neither crowded nor safer.

  Mr. Ben Soh has just finished watching The Bridge Curse in Singapore Cinema, and he commented that the viewing experience was reassuring because all the safety measures were strictly put in place.

  After more than 100 days of business suspension, cinemas in Malaysia reopened on July 1. Although there is no new film released, many viewers still choose to return to the cinema to watch the movie live to support the box office, and the operators are deeply grateful for this.

  On July 16th, a spokesman for MBO Cinema said in an interview with Malay Post that the selling rate of movie tickets is slowly increasing. In the past two weeks, the average attendance rate was between 15% and 25%. He said: "At present, our strategic plan is to operate at the optimal level first, and then we will recover the indirect expenses of the cinema in the next few months." However, the spokesman also admitted that how to gain the trust of customers under the new normal and how to solve the problem of lack of new movies brought about by the epidemic are severe challenges for them.

  prevent epidemics

  Safety should also be ensured when returning to work.

  Encourage advance booking of popcorn.

  "Minions" will accompany you to the movies.

  Trial operation of "Contactless Cinema"

  Although cinemas all over the world have gradually joined the ranks of returning to work, as a gathering place, cinemas still need to take a series of prevention and control measures to ensure the safety of customers and staff during the special period when the epidemic has not completely ended.

  In Britain, cinemas in England resumed business on July 4th, while the opening dates of Northern Ireland, Scotland and Wales were set on July 10th, 15th and 27th respectively.

  The British Film Association has issued corresponding guidelines for this purpose, including:

  ● A certain social distance should be kept between seats, and people from different families should sit separately to limit the number of people in each screening hall;

  ● Stagger the movie playing time, so as to avoid the hall being crowded;

  ● Hand sanitizer and extra cleaning work need to be provided, and employee training should be actively organized;

  ● Encourage people to book online as much as possible, and use electronic tickets and contactless payment;

  ● The sales mode of mixed snack packages will be cancelled, and consumers are encouraged to book popcorn in advance.

  In addition, cinemas will also implement special seat selection schemes. Admit One, which provides ticketing services for ordinary cinemas and multi-hall cinemas, said that when customers book tickets online, the system will automatically generate "bubbles" on the seats around them to maintain a safe social distance. Some cinemas may not allow consumers to choose their own seats, because this may affect the occupancy rate of cinemas.

  Admit One also said that the average width of a seat in a cinema is about 60 cm and the depth is about 97 cm. Therefore, in order to meet the requirement of "2 meters interval between seats", the cinema must leave 12 empty seats around an audience and 16 empty seats around a couple. However, if the social safety distance is 1 meter, cinemas can choose other configuration schemes, but most cinemas can only accommodate customers with about half the seats.

  In France, when going to the cinema, there are no longer "empty" seats around, but those lovely "Minions" dolls. In 2015, these yellow drug-shaped toy figures first appeared in front of the French in the cartoon "Minions" shown in MK2 cinema in the south of Paris. This year, "Minions" wore iconic goggles and work clothes, solemnly "sat" next to the audience, forcing them to leave a safe distance. Cinema trips are not the first time that "Minions" people have been recruited to protect the safety of the audience. They have also appeared in the short public service advertisements jointly launched by the World Health Organization, the United Nations Foundation and lighting and entertainment companies, vividly sharing with the world how to protect each other and protect the community in this epidemic.

  Nowadays, chain cinemas in South Korea are also "racking their brains" to plan new plans, hoping to make fans come back to the cinema more comfortably and safely. CJ-CGV, the largest cinema in South Korea, has launched a "contactless cinema" mode in a sub-cinema in Seoul, where popcorn, hot dogs and soft drinks are moved into vending machines, while other snacks are placed in the sales office and delivered through contactless boxes. Two roving robots have replaced the ticket sellers, and you can know the movie screening time and other cinema information through the touch screen on the robots.

  "This is more hygienic than face-to-face communication, customers will feel safer, and this way is more interesting and cool." Li Seung-soo, an employee of CGV, told VOA. He also said that before the COVID-19 epidemic forced enterprises to take social or physical isolation measures, CGV Company was already considering introducing some automation facilities for cinemas, and the urgency of epidemic prevention eventually led to the emergence of the "contactless cinema" model. In addition, CGV cinemas will regularly disinfect the cinema facilities and leave enough safe space between the audience.

  "This contactless cinema mode of the branch is still in the testing stage." Li Shengzhu added, "According to the progress of this project, we will decide whether to introduce this kind of service in other theaters."

  Coup

  There are many fancy movie theaters.

  Drive-in theaters are sought after again.

  Floating cinema has a unique style.

  Romantic viewing on the Seine River

  In addition to watching movies in cinemas and at home, the epidemic has also spawned a variety of ways to watch movies, and the back-favored drive-in cinema is one of them.

  Drive-in cinema is a special form of cinema, which consists of a large outdoor movie screen, a projector, a snack bar and a parking lot. Fans can watch the big screen in their car and listen to the movie sound on the car radio. During the epidemic period, drive-in cinemas rose again all over the world because of their unique advantages such as privacy and security. According to the latest data from measurement company Comscore, the number of drive-in cinemas in Britain has soared from 3 to 40.

  In the United States, as part of its cooperation with Tribeca enterprises, Wal-Mart will turn its 160 parking lots into contactless drive-in cinemas from August, which will increase the total number of drive-in cinemas in the United States by at least 50%. "Since we held the Tribeca Film Festival 19 years ago, the drive-in cinema has been a landmark project in Tribeca." Jane Rosenthal, founder of Tribeca Enterprise, said in a statement, "Tribeca drive-in cinema is not only an interesting and nostalgic way to watch movies, but also one of the safest ways for people to gather. We are very happy to cooperate with Wal-Mart to bring more people together and share this special movie-watching experience. "

  The drive-in cinema will last until October this year, covering a total of 320 movies. The specific list of movies to be shown is yet to be determined, but Wal-Mart said that movies suitable for families and "special appearances of filmmakers and other celebrities" will be included.

  Wal-Mart is not the only company that has converted its parking lot into a cinema. The Marcus chain cinema in the midwest of the United States has also launched a drive-in cinema project this year, and has formulated a series of epidemic prevention measures to ensure the safety of the audience. The cinema emphasizes that sick people should stay at home, and customers who choose to watch movies should also wear masks in the cinema lounge or when collecting coupons.

  If you think it’s a little depressing to watch movies in such an airtight car, you might as well try to get some fresh air on the boat.

  Beyond Cinema, headquartered in Sydney, will set up water cinemas in many cities in Australia and the United States, so that the audience can enjoy the scenery while watching movies.

  "The cinema will consist of 12 to 24 mini-boats, each of which can accommodate up to 8 people." Beyond Cinema official website’s registration page shows, "You will need to pay the ticket price of the whole boat to ensure that only family and friends can sit together, thus maintaining the social distance between the boats."

  New york’s water viewing time is scheduled for one week from September 16th to September 20th this year. The specific movie playlist has not yet been announced, but officials say both classic old movies and new movies will be covered.

  Beyond Cinema is not the only organizer of "Floating Cinema" — — On the banks of the Seine in France, the "Paris Beach Festival" also held a grand water viewing ceremony.

  The "Paris Beach Festival" is an activity held in France every summer. During the event, some areas along the banks of the Seine will be paved with sand to form artificial beaches, providing Parisians with a place to relax.

  This year, Paris cooperated with MK2 Cinema to hold a water viewing celebration. On July 18th, the audience can choose to watch the French comedy "The Grand Bath" on an electric boat or on a chair on the river bank. Elisha Karmitz, CEO of MK2 Cinema, said in an interview with Euronews: "After several months of city blockade, we think we should find a suitable way to tell people and the world that the cinema has reopened in Paris, the movie capital of the world."

  The way to survive after the epidemic

  Although the reopening of cinemas paved the way for the release of new films, and the fancy viewing mode also provided new ideas for the development of the industry, we still can’t ignore the heavy blow suffered by the film industry during the epidemic.

  On March 4th, 007 official Twitter announced that the series "007: No Time to Die" originally scheduled for release in April will be postponed to its premiere in November, which is the first Hollywood film in North America to be postponed due to the epidemic. Changing the release date is undoubtedly a huge loss for the film, which means that huge publicity expenses have hit Shui Piao, which is like the first stone thrown into the water, causing ripples in the film circle. On April 4th, Mulan announced that the release date of the film would be postponed from March 27th to July 24th, while Tenet, which was originally scheduled to be released in July, was also postponed to August due to the epidemic, and this date was postponed again recently.

  According to the Guardian, director Nick Rowland’s first film "Rest on a Horse" was originally scheduled to be released on March 27th, but as the release date approached, he felt more and more anxious. "Around January and February, I noticed the news that the COVID-19 epidemic began to spread in Europe. I suddenly realized that when" Leaning on a Horse "was released, it happened to be the most serious moment of the London epidemic. What would you do in this case? I’m ambivalent, but it’s too late to postpone the release now, so we have to promote it. But at the same time, we have to advise our family and friends to stay at home and watch movies instead of going to the cinema. It took me six years to shoot this film, but I only got a few days to show it, which is really unacceptable. "

  On June 19th, the British Film Association and the Film Publishers Association organized a film industry recovery plan called "Restarting Cinema: Content Recovery" through the cross-industry group "Cinema First", and created a huge film library of 450 films including Hollywood classics, independent films and modern blockbusters to help cinemas recover quickly after several months of suspension. Andy Leyshon, CEO of the British Film Distribution Association, said: "We value you, we miss you, and this time we support you with some really great movies."

  Film production around the world is still in a state of stagnation, and films such as Avatar sequel and Jurassic World: Sanctuary The Matrix 4 have been forced to suspend production due to the epidemic. According to the data of statista information platform, as of mid-March 2020, the revenue loss of the global film industry has reached 7 billion US dollars, and it is estimated that this figure is likely to increase by another 10 billion US dollars in April and May.

  In order to alleviate the pressure brought by the cancellation of the premiere, the closure of cinemas and the sharp drop in box office, film companies are constantly seeking new profit growth points, and the streaming media platform has become their target. Disney+is a streaming media service platform launched by Disney. During the period from February to May this year, the number of subscribers of the platform has doubled to more than 50 million. Trolls World Tour, the new film of Universal Pictures, directly crossed the cinema and implemented the online on-demand mode. In the first three weeks of its release, it achieved nearly $100 million in revenue, exceeding the income generated by the first film "Magic Hair Wizard" in the cinema for five months. Moreover, the film company will get a higher percentage of revenue rebate if it chooses to release online, which is about 80%, while the cinema release is only 60%.

  Italy’s Circuito Cinema combines online and offline broadcasting, and launched a transactional video-on-demand platform plan called MioCinema on May 18th. On this platform, viewers can pay 7 euros to watch a movie online, and 40% of each online payment can be used to buy movie tickets for cinemas that are still closed. But when the epidemic is stable and everything returns to normal, the cinema and streaming media will be separated again.

  Although the online platform seems to provide a virtual space where movies can be played permanently, various video websites, the projection of the living room at home, and the computer screen that can be fast-forwarded at any time can’t replace the touching silver screen. Many fans are still eagerly looking forward to returning to the cinema and completely immersing themselves in the beautiful light and shadow outside ordinary life in the "dark" space. Richard Linklater, an American producer, said in an interview in The New York Times: "This is a common dream, starting with filmmakers and ending with the audience, in a space that is now regarded as more fragile, where we all agree to get together quietly."

  Before a cinema in San Francisco closed down, it left a message on the sign at the door, "Keep healthy and safe, and then we will come back soon."

  This is also the deep expectation of all people who love movies. This edition/Zhangyuan

Scientists make glass "rejuvenate"

  ◎ Intern reporter Li Zhao Yu Dou Peng

  From towering skyscrapers to small and exquisite chronograph watches, glass can be seen everywhere in life.

  Peng Shou, deputy to the National People’s Congress, academician of China Academy of Engineering, chief engineer of China Building Materials Group and president of China Building Materials Research Institute of Glass New Materials, said in an interview that it is necessary to vigorously promote energy conservation and carbon reduction in the glass industry, so that the glass industry in China can "go green".

  In fact, glass should not only "go green", but also be expected to "rejuvenate" — — With the increase of service time, glass will age, which is usually accompanied by the deterioration of physical and mechanical properties. In recent years, more and more attention has been paid to how to "rejuvenate" aging glassy substances and restore their properties.

  At the end of 2022, Jiang Minqiang, a researcher at the Institute of Mechanics, Chinese Academy of Sciences, revealed a new mechanism for the rejuvenation of severely aging metallic glass through research, which deepened the understanding of the rejuvenation of glass structure. Relevant research results were published in Fundamental Research, a multidisciplinary English journal headed and sponsored by the National Natural Science Foundation of China.

  Glass aging: a slow transition from disorder to order

  To make glass "rejuvenate", we must first understand how glass "ages".

  Jiang Minqiang introduced that from a microscopic point of view, glass is an amorphous solid with irregular structure. He gave an example to the reporter: in crystalline solids such as steel, atoms are arranged in an orderly manner like students sitting quietly in a classroom, showing a regular shape. In glass, an amorphous solid with irregular structure, atoms are just like students after class, running around the campus, showing a disorderly arrangement.

  The phenomenon of glass aging, in essence, is the transition of glass from the disordered state when it was initially formed to the orderly state. "Generally speaking, the total energy of matter is higher in disorder state, while in order state, the total energy of matter is lower. As time goes on, glass will gradually change from a high-energy state to a low-energy state. This process is generally called glass aging. " Jiang Minqiang explained that if the aging time is long enough, or the aging is accelerated by heating up, the glass can even be transformed into a solid crystal with a regular structure.

  Glass aging will affect many properties of glass, such as toughness, optical properties and electrical conductivity, which is a phenomenon that people want to delay or even avoid. Therefore, as a process of reversing glass aging, glass rejuvenation has long been widely concerned by researchers.

  "The rejuvenation of glass is the reverse process of glass aging, that is, the glass that makes the atoms relatively orderly after aging slowly returns to the relatively disordered state of atoms." Jiang Minqiang said. In the previous research on glass rejuvenation, the researchers found that the younger glass will release some enthalpy when it is heated to a certain temperature, and the higher the younger the glass is, the more enthalpy will be released during heating. Enthalpy is an important state parameter to characterize the energy of material system. Generally speaking, enthalpy is the energy released by young glass during heating.

  "Our research believes that the above views do not apply to severely aging glass. With the increase of the degree of youthfulness, the enthalpy release of severely aged glass has not changed, or even has no enthalpy release at all. " The research of Jiang Minqiang’s team shows that the previous views on glass aging mechanism are not applicable to severely aging glass, which updates people’s understanding of the mechanism of glass structure rejuvenation.

  "Unintentionally inserted willow": The research result is unexpected.

  "In fact, the breakthrough of this research stems from our research team ‘ Unintentionally inserted willow ’ An attempt. " Jiang Minqiang said that the initial purpose of this experiment was only to prepare experimental samples. "Our team originally prepared samples for another experiment. In order to strengthen the scientific nature of the experiment, it is necessary to eliminate the thermal history of the samples and ensure that their structures are consistent. We anneal the glass samples at low temperature — — Slowly heat the metallic glass to a certain temperature and keep it for enough time, and then cool it to room temperature at a certain speed. " Subsequently, the research team rejuvenated these glasses in a severely aging state through mechanical deformation. The result was unexpected — — "We obviously input energy into the glass through mechanical work. Why don’t these glasses release enthalpy and become younger?" This is contrary to the previous mainstream view.

  This result puzzled the research team. In order to solve the mystery, in addition to measuring enthalpy, the research team also measured the high temperature of glass samples (450K— 750K) and low temperature (1.9K— 100K), and then the atomic vibration information and topological structure information of glass are investigated. "In the course of the experiment, the research team found that although the parameter of enthalpy release before glass transition remains unchanged in some cases, the effective enthalpy change during glass transition and the atomic vibration Bose peak reflected by low temperature specific heat will change accordingly." Jiang Minqiang further explained, "This shows that enthalpy release is not the only physical quantity reflecting the rejuvenation of glass."

  When talking about why the enthalpy release remains unchanged, Jiang Minqiang once again explained with vivid examples: "If we put a ball in ‘ Concave ’ The concave part of the zigzag plane, this ball will naturally remain in place. This stable state is like severely aged glass. And if we put this ‘ Concave ’ The zigzag plane is inclined at some angles. Although the height of the recess, that is, the energy level of the glassy substance, remains almost unchanged, the glass state represented by the ball will become unstable, and then the phenomenon of glass rejuvenation will appear. "

  The results show that, in addition to the previous mainstream point of view, the rejuvenation of glass can be directly reflected in the release of enthalpy, that is, the improvement of energy level, and can also be reflected in the inclination of energy plane, that is, the free volume can be redistributed in space through local structural rearrangement. "This is also the new mechanism of rejuvenation of severely aging glassy substances that we have discovered." Jiang Minqiang said.

  Expand the scene: provide a broad application space

  This study also found that with the glass entering a steady flow state, the above three physical parameters representing the rejuvenation will tend to saturation values, so it was first determined experimentally that the upper limit of the glass structure rejuvenation was a "frozen" steady flow state.

  If water is used as an analogy, glass that forms liquid at high temperature is like water, while glass that solidifies at low temperature is like ice. "The limit of the rejuvenation of the glass structure is that the high-temperature glass liquid is suddenly frozen by rapid cooling, thus forming a similar ‘ Frozen running water ’ The material state. " Jiang Minqiang explained, "In this case, the glass will maintain almost the same material structure as the liquid state under the solid appearance, and its fluidity will reach the limit of current understanding."

  The new mechanism of rejuvenation of glassy materials revealed in this study not only allows us to better understand the related causes and processes of glass aging in physical essence, but also has great potential application space in promoting the batch rejuvenation of aging glass. "The research team is currently communicating with companies engaged in glass production or research and development, trying to find a good combination point to promote technology to the market."

  In addition, Jiang Minqiang also found that the new mechanism revealed in this study is also expected to be applied to the preparation of advanced metal materials.

  "Generally speaking, the strength and toughness of metal materials cannot be both. With the increase of strength, toughness will decrease, and vice versa. " Jiang Minqiang said, "How to overcome this inherent inversion relationship is a problem that must be faced in preparing advanced metal materials with both strength and toughness."

  The total energy level of high-strength metal materials at the microscopic level is generally very low. If energy is input by heating and other methods, it is almost impossible to try to improve the toughness of metal materials by raising the total energy level, which often requires extremely high energy input.

  "If we can use the new mechanism discovered in this study to adjust the energy plane angle of metal materials when the total energy level is low, we can improve the disorder of atoms and enhance the toughness of metal materials while maintaining the macro strength unchanged. Through this method, we can effectively avoid huge energy input and greatly reduce the cost of preparing high-toughness metal materials. " Jiang Minqiang said that his team is constantly trying to make a decisive breakthrough and provide new ideas for solving the irreconcilable contradiction between the strength and toughness of metal materials for a long time.
