When 2020 came, hundreds of millions of people did not expect that the Gengzi New Year would open in this way. The sudden COVID-19 epidemic made people feel the fragility of life, and at the same time made people understand that only health is the greatest happiness.

Bread is the staff of life. Health is inseparable from the scientific guidance of daily diet nutrition, and it is not enough for people to know the importance of nutrition, but also to know how to obtain scientific nutrition methods. It can be predicted that almost every family in China will need a professional family nutritionist in the future.

"Healthy China 2030" focuses on disease prevention.

The CPC Central Committee and the State Council attached great importance to people’s health, and successively issued a series of important policies. Among them, the Outline of Healthy China 2030 pointed out that it is necessary to speed up the transformation of the development mode in the health field, safeguard and protect people’s health in an all-round and full-cycle manner, and greatly improve the health level.

In recent years, chronic diseases have surpassed acute infectious diseases and become the biggest killer of Chinese health. With the development of social economy, the nutritional health status of Chinese residents has been continuously improved. However, due to management, education and popularization, people’s dietary nutrition structure is not reasonable, and the phenomenon of high salt, high sugar, high fat and high uric acid is prominent. Adult hypertension, diabetes, high uric acid and dyslipidemia have become common public health problems.

People are beginning to realize that the imbalance of diet and nutrition is the culprit of all kinds of chronic diseases, and the concept of health is no longer "disease treatment" but "disease-free prevention". Fortunately, many chronic diseases can be prevented or controlled at an early stage. As long as there is scientific and timely guidance, there is no need to drag them to the point of "minor diseases and serious illnesses, and serious illnesses will kill people".

"Nutrition e-student" innovates the concept of nutrition intervention

The health guideline advocated by the government to change from treatment to prevention coincides with the concept of "everyone has a health record and every family has a nutrition doctor" on the "Nutrition E-student" APP platform.

The "Nutrition E-Student" APP is an Internet home nutrition intervention and chronic disease management service platform developed by Wuhan Lvan Jianfang Science and Technology Co., Ltd., which pioneered the concept of "network nutrition hospital", "network nutritional treatment and one-stop nutritional intervention solution for chronic diseases" and "dietary nutrition tester" which is leading in China and advanced in some countries.

In the treatment and recuperation of chronic diseases, people are most likely to be confused-is their way of recuperation correct? Some people suffer from recurrent illness due to lack of dietary nutrition and self-discipline; Some people lack common sense and daily guidance, and consciously become a doctor after a long illness, with minor and chronic diseases and serious emergencies.

As a user of the "Nutrition E-student" APP platform, there will be no such troubles. The platform not only avoids the risk of travel fatigue and infection, but also can enjoy rich dietary nutrition information and scientific and technological achievements dietary nutrition tester without leaving home. The platform has also organized a team of nutrition and health experts, service teams and many professional cooperation institutions at home and abroad to provide users with one-stop nutrition intervention programs for chronic diseases, so that the nutrition and health of China families will no longer be in crisis.

Internet nutritionists enter thousands of households.

The Healthy China Action (2019-2030) issued by the State Council pointed out that by 2030, every 10,000 people should be equipped with a nutrition instructor, but at present, the number of professional nutritionists in society is extremely rare. At the same time, there are as many as 260 million chronic patients in China who need professional nutrition intervention services to improve their quality of life. The contradiction between supply and demand is very obvious.

While demand is hot, supply is scarce. How to solve the current contradictory situation of nutritional intervention for chronic diseases? The "Nutrition E-student" APP platform provides a perfect solution by providing Internet nutrition and health intervention services. The platform provides online consultation through one-to-one nutrition housekeeper, and uses a large database based on China Food Composition Table (2018) to provide users with dietary nutrition evaluation and nutritional risk screening, and provide users with services such as general nutrition guiding principles, daily meal arrangement, scientific exercise guide and daily drinking water.

In addition, for users who need professional dietary nutrition guidance, the platform also provides more than 200 domestic and foreign nutrition and health experts for real-time online video consultation, and through professional nutrition intervention programs, personal physical function can be improved from aspects such as conditioning physique, improving basic quality and improving human nutrition environment.

The "Nutrition E-Student" APP platform is currently working closely with China Nutrition Society, china health care association, China Anti-aging Promotion Association and other institutions to vigorously promote the comprehensive popularization of Internet nutrition diagnosis and treatment. Behind the "nutrition e-students" are a group of professional "Internet nutritionists" who are entering thousands of households with the grand vision of "staying at home and enjoying the home nutrition intervention program"!

Seven departments, including Beijing Medical Insurance Bureau, recently jointly issued the "Implementation Opinions on Improving the Medical Insurance and Assistance System for Serious and Serious Diseases", proposing that starting from 2023, there will be no minimum payment standard for medical assistance, and the ceiling line for family assistance caused by illness will be raised from 80,000 yuan to 150,000 yuan, and the proportion of assistance will remain unchanged.

It is clear in the implementation opinions that there will be no deductible standard for medical assistance from 2023. The outpatient and inpatient medical expenses borne by individuals within the scope of basic medical insurance reimbursement are all included in the scope of medical assistance in Beijing. Medical assistance covers all needy workers and urban and rural residents who have heavy medical expenses and have Beijing household registration and participate in basic medical insurance, as well as social assistance objects such as poor, low-income and low-income people who have participated in basic medical insurance as recognized by the civil affairs department. At the same time, all social assistance objects participating in employee medical insurance and residents’ medical insurance are given equal assistance, realizing full coverage of Beijing household registration personnel. The implementation opinions will be implemented as of January 1, 2023. If there is any inconsistency between the medical assistance policy and the implementation opinions, the implementation opinions shall prevail.

The objects of medical assistance in Beijing are divided into two categories: the first category is social assistance objects, including destitute dependents and educated youth who are disabled due to work (illness) and returned to the city under the management of civil affairs departments; In the early 1960s, the civil affairs department managed to streamline retired old workers who enjoyed 40% of the original salary; The minimum living security object and the subsidy personnel for living difficulties; Urban and rural low-income family rescuers. The second category is the seriously ill patients from poor families due to illness, that is, the registered permanent residents in Beijing and their family members who live together have serious difficulties in their basic life because they do not meet the conditions for the identification of social assistance objects in Beijing, and their medical expenses are relatively high in a natural year. After basic medical insurance, serious illness insurance, commercial insurance reimbursement and various kinds of assistance, the medical expenses borne by the family exceed the family’s affordability.

The medical expenses incurred by social assistance recipients during medical treatment, after being reimbursed by basic medical insurance and serious illness insurance, can enjoy three types of assistance according to the policy: outpatient assistance, hospitalization assistance, and assistance for seriously ill patients in poor families due to illness. In the outpatient service, the poor dependents in the social assistance object, the educated youth who are disabled and return to the city because of work (illness) managed by the civil affairs department, and the personal burden within the scope of the policy are given assistance according to 100%, and there is no maximum payment limit for annual assistance; Among the social assistance objects, the retired old workers who enjoyed 40% of the original salary in the early 1960s managed by the civil affairs department were reduced, and the personal burden within the policy scope was given 80%, without setting the maximum payment limit for annual assistance; In addition to the above-mentioned personnel, the social assistance object will be given assistance according to 80% of the personal burden within the policy scope, and the maximum payment limit for annual assistance is 8,000 yuan.

In terms of hospitalization assistance, the poor dependents in the social assistance object and the educated youth who are disabled due to work (illness) managed by the civil affairs department will be given assistance according to 100% of the personal burden within the scope of the policy, and there is no annual maximum payment limit for assistance; Among the social assistance objects, the retired old workers who enjoyed 40% of the original salary in the early 1960s managed by the civil affairs department were reduced, and the personal burden within the policy scope was given 85%, with no annual maximum payment limit for assistance; In addition to the above-mentioned personnel, the social assistance object will be given assistance according to 85% of the personal burden within the policy scope, and the maximum payment limit for annual assistance is 160,000 yuan.

After deducting the basic medical insurance, serious illness insurance, commercial insurance reimbursement and various kinds of assistance, the personal burden part within the policy scope will be given medical assistance in stages according to the proportion of 30% below 30,000 yuan (inclusive), 40% above 30,000 yuan to 50,000 yuan (inclusive) and 50% above 50,000 yuan.

In addition, for the social assistance recipients who have been referred for the first visit at the grass-roots level, the hospitalization in the designated medical institutions of basic medical insurance in Beijing will be "paid after the first visit", and their hospitalization deposit will be completely exempted. For those who did not participate in Beijing’s basic medical insurance in the implementation opinions, after being reimbursed by other cities’ basic medical insurance, the outpatient and inpatient medical expenses borne by individuals within the policy scope can be given assistance according to the above corresponding categories of assistance standards.

　　Hold a symposium on biological science work
　　　　From April to June, the Science and Health Department of the Planning Bureau of the Cultural Affairs Committee of the State Council and the Planning Bureau of the China Academy of Sciences held three symposiums on biological science work, criticizing the mistakes made by Le Tianyu, the director of the Genetic Selection Laboratory, when he was the chairman of the School Committee of Beijing Agricultural University (1949-1950). The meeting also discussed the status and problems of biological science and exchanged views on future work. The symposium was attended by relevant leaders and experts from Culture and Culture Commission, Academy of Sciences, Ministry of Agriculture, Peking University, Tsinghua University, Agricultural University and North China Institute of Agricultural Sciences. On June 29th, People’s Daily published an article "Struggle for Adhering to the Direction of Biological Science in michurin" written according to the discussion conclusion of the symposium. It is pointed out that Le Tianyu has serious bias and mistakes in empiricism and dogmatism, his arbitrary unscientific attitude and bad academic style, and regards Mi Qiu forest biological science as a whip to hit people, which has caused losses to the national scientific cause. Although this paper criticizes Le Tianyu’s mistakes in this respect, it also thinks that the current situation of biological science in China has reached an intolerable level, and we must fight for adhering to the direction of michurin. To continue to systematically criticize the influence of Morganism on all aspects of old biology, we should not only transform genetics with Michulin biology, but also completely transform all biological departments in China.
　　After the publication of the article, the relevant departments or majors of universities across the country stopped teaching Morgan genetics courses; The research work under the guidance of Morgan school theory was forced to stop, and even the hybrid breeding work that had been achieved was interrupted because it was regarded as Morgan doctrine; Academic journals only published articles of lysenko school, and some geneticists were forced to publish articles against their will. By holding meetings in the name of the government and publishing important articles in party newspapers, supporting one school and suppressing another school has had a very bad influence on the development of genetics and biological sciences.
　　Participate in the scientific investigation of anti-bacterial warfare.
　　From February 29th to March 5th, American planes invaded the northeast and scattered insects and leaves with bacteria for more than 400 times. On March 7th, two vice presidents, Zhu Kezhen and Wu Youxun, published a statement in People’s Daily against the US military’s germ warfare. With the backyard, scientists will be organized to conduct scientific investigations, and the specific tasks will be undertaken by the insect research room of the Institute of Experimental Biology. Ma Shijun and his assistant, who were sent to the northeast for investigation, collected the insect carcasses scattered by American planes in various areas in mid-March, and saw the remains of bacterial bombs and many feathers used to carry germs. On March 29th, at the enlarged meeting of the Executive Board of the World Peace Council, Guo Moruo suggested that the World Peace Council should organize an international committee to investigate the crime of spreading bacteria by the United States in China and North Korea.
　　In mid-June, members of the "International Scientific Committee to Investigate the Facts of Bacteriological Wars in North Korea and China" composed of scientists from Sweden, France, Britain, Italy, Brazil and the Soviet Union arrived in Beijing. Qian Sanqiang, a Chinese physicist, is the liaison officer. Scientists from China Academy of Sciences participated in the investigation. Chen Shixiang, director of the Insect Research Office of the Institute of Experimental Biology, led the staff in the room to identify a variety of insects scattered by US military aircraft and wrote "Some Facts about Insects in the Report of the International Scientific Committee on the Investigation of American Bacteriological War". Zhu Hongfu, together with members of the International Scientific Committee, set off from Beijing in early July and went to northeast China and North Korea for investigation. Botanists Qian Chongzhu, Lin Rong, Hu Xiansu, Yu Dexun and Wu Zhengyi from the Institute of Botanical Taxonomy identified the leaves removed by the US military aircraft, and confirmed the germ warfare crimes of the US military. On August 31st, the signing ceremony of the Report of the International Scientific Committee to Investigate the Facts of Bacteriological Warfare in China and North Korea was held in Beijing. The conclusion of the report is: "People in North Korea and Northeast China have indeed become targets of bacteriological weapons, and the US military has used these weapons in many different ways.". The report affirms a great deal of work done by scientists in China in scientific investigation and analysis. Subsequently, the Special Issue of Anti-Bacteriological Warfare was published by Science Bulletin.
　　Northeast branch established
　　From mid-April to early May, 1951, a five-member delegation led by Vice President Wu Youxun visited Northeast China to discuss the establishment of working relations between the Academy of Sciences and scientific research institutions in Northeast China. The Ministry of Industry of the Northeast People’s Government suggested that the Academy of Sciences set up a metallurgical research institute in Shenyang, and hoped that the Academy of Sciences would set up a branch in the Northeast. On June 9th of the same year, after listening to Wu Youxun’s report, the president’s meeting decided to build the Northeast Branch, and the preparatory office of the Northeast Branch was established on October 13th.
　　On August 28th, 1952, the Northeast Branch of China Academy of Sciences was formally established in Shenyang, with Yan Jici as the president and Wu Heng as the secretary-general. At the beginning of the branch, there were Changchun Comprehensive Research Institute, Industrial Chemistry Research Institute and Physical Chemistry Research Institute, and then metal institute, instrument hall, civil construction institute and forestry soil institute were established one after another. Later, the chemical part of Changchun Comprehensive Institute merged with the Institute of Physical Chemistry to form the Institute of Applied Chemistry, while the Institute of Industrial Chemistry was transformed into the Institute of Petroleum.
　　After the national administrative region was abolished in 1954, the Northeast Branch was also abolished. The Academy of Sciences changed its office in Shenyang.
　　Hold a joint meeting of directors in Beijing to discuss and formulate the work plan for 1953.
　　From September 8 to 26, the Academy of Sciences held a joint meeting of directors in Beijing, and listened to the heads of heavy industry, fuel, textile industry, agriculture, forestry, transportation, health, water resources, education and meteorological bureau of the Military Commission, and reported on the work of each department and their requirements for the research work of China Academy of Sciences. On 26th, the Planning Bureau of the Ding Zan Representative Institute made a report on "Several Opinions on Making a Scientific Work Plan" at the meeting, expounding the purpose of making a scientific work plan, the principles on which the plan is based and the problems that should be paid attention to, analyzing the basic situation and existing problems of scientific work in China, and putting forward some reference opinions on the research tasks of various institutes in Beijing. On January 19th, 1953, the executive meeting of the Academy discussed and adopted the Work Plan of China Academy of Sciences in 1953. The main research work is as follows: 1. Investigation of national natural conditions and natural resources; 2. Cooperate with the scientific research of national industrial construction; 3. Cooperate with the research of agricultural and forestry production practice; 4. Basic research in physics, chemistry, biology, geoscience and sociology. In addition, plans have been made for the promotion of achievements, the organization of academic conferences, the development and adjustment of scientific research institutions, personnel training, compilation and publication, capital construction and financial estimates.
　　Make a resolution on strengthening the study and introduction of advanced science in the Soviet Union
　　On October 24, Guo Moruo presided over an enlarged dean’s meeting to discuss how to strengthen the study and introduction of advanced science in the Soviet Union. Guo Moruo first welcomed and thanked the Presidium of the Soviet Academy of Sciences for adopting a resolution on creative cooperation with scientists in China on October 3rd. After discussion, the meeting made the Resolution of China Academy of Sciences on Strengthening the Study and Introduction of Advanced Science in the Soviet Union. The measures taken are as follows: (1) require all research units to strengthen their research on the scientific achievements of the Soviet Union and put forward suggestions to the relevant administrative departments of the state on adopting the achievements of the Soviet Union in practical work; Immediately start publishing the Soviet Science Series, and the Science Bulletin will systematically introduce the latest achievements of Soviet science; China Academy of Sciences cooperated with the National Federation of Science and Technology, the National Science Popularization and other units to hold exhibitions and lectures introducing Soviet science and scientists; Organize a delegation to visit the Soviet Academy of Sciences, learn from the advanced experience of the Soviet Union, and discuss specific measures for scientific cooperation between China and the Soviet Union.

If you open the column,

Short video has become an extremely eye-catching media landscape in this era.

The video in just a few minutes or even tens of seconds captures the colorful moments of daily life, is a glimpse of fireworks in the city, is a silhouette of humanistic customs, and is a quick view of social conditions. In the flowing picture of short videos, the world is unfolding at the speed of light. Regardless of occupation, regardless of age, as long as the mobile phone is in hand, there will be "unstoppable" fun. But on the other hand, many people are also thinking about the speed and quality of information dissemination, fragmented expression and knowledge coherence, superficial prevalence and deep thinking exit.

Undoubtedly, short videos are deeply involved in the construction of people’s spiritual and cultural life. From now on, this edition will open the column "Observation of Short Video Cultural Phenomenon", sort out the deep logic and media characteristics of short video popularity, analyze the internet users’ emotions and popular cultural psychology behind "everyone brushes short videos", and try to put forward feasible suggestions on opening short videos correctly.

Many people did not expect that short videos could be so short. Most short videos are recorded by mobile phones: in a few minutes or even tens of seconds, a complete unit of expression has been completed-the theme, the characters, the small plot twists and turns, and all the necessary elements are available. Perhaps, people can re-recognize the expressive potential of image symbols: short image editing may show more meaning than expected. We can often see on the Internet that a two-hour movie is compressed into a short video introduction of eight or nine minutes, and the ins and outs of the story have clearly emerged.

In contemporary culture, the tension between large-scale works and small-scale works is unprecedented. Some people love forty episodes of TV series, and many fans continue to follow online novels with millions or even more than ten million words. A few pages of short stories or lines of poems do not seem to be "enjoyable"; On the other hand, "jokes", jokes, talk shows and cross talks are short, and Weibo was once limited to 140 words. Short video is obviously a masterpiece of "small". Are there any works shorter than tens of seconds of image symbols?

Many experts always follow an explanation model for small works: the pace of life is getting faster and faster, and many people are as busy as gyroscopes. They have no time or patience to deal with those large works. The era of WeChat has arrived, and a message reaches the other side of the world within half a second. So many things happen and disappear so quickly, all walks of life and personal senses must mobilize and do their best to adapt to this speed. At this time, the birth of short video coincides with its meeting. Of course, this explanation quietly shields another possibility: do people just enjoy and not resent the galloping pace control of life?

one

As an echo of this rhythm of life, the video length of several minutes or even tens of seconds is only an external appearance, and what is important is that the meaning of image symbols is unobstructed. From news scenes, pet amusements, and fitness tips to a dance, a song, and a game clip, the clear content of various short videos is like a concise table. There is nothing that needs to be pondered over and over again; The decoding of symbolic images or prototypes is rather gilding the lily. Easy browsing and unimportant topics just fill the time gap that has not been covered by busy work.

However, easy browsing, unimportant themes, faster and faster pace of life or image symbols are precisely the contents criticized by many humanistic intellectuals. Easy browsing can only swallow those cultural fast foods that lack nutrition. After the spiritual space is full of inferior products, classic culture no longer has a place to live. Worryingly, easy browsing and unimportant topics are training a superficial reading style. With short space and clear content, people’s eyes and thoughts can only adapt to some cultural fragments. Thick cultural classics and abstruse phrases are overwhelmed, and movies, music and paintings with unfamiliar forms are decisively abandoned because they don’t know what they mean. Even so, humanistic intellectuals have no reason to advocate an absurd premise: obscurity is the symbol of cultural value. However, they are worried about a lack of ideological ability. If the superficial reading style evolves into spiritual normality, and if analysis, research, doubt and criticism are all regarded as dazzling skills that make much ado about nothing, then the spiritual quality of the nation may decline rapidly from the level set by classical culture. Of course, this concern goes far beyond the scope of classics reading. When the ideological ability is incompetent, people will certainly explain the complex cultural structure and even historical phenomena in various self-righteous ways.

When the superficial reading style is traced back to the source, many humanistic intellectuals openly contradict the current pace of life. Whether it is the efficiency of the production system, the speed of economic and commodity turnover, the transportation system and the cultural media, the industrial society is driving the great speed-up of history. From the worldly wealth growth, the iterative upgrading of scientific knowledge to the numerous information received by the senses, people can find the profound consequences of this speed-up in various fields. However, the fundamental question that a group of humanistic intellectuals are trying to ask is: where is the accelerated history going? It can be seen that there are still many injustices, disasters, disparity between the rich and the poor or the competition for resources has not slowed down. Man is hurrying along under the lash of his own desires. A faster pace of life is usually associated with more income. However, is more money greater happiness?

Philosophers advocate living a "contemplative life", and they use "hyperactivity" to describe this restless mental state. However, the weak doubts of humanistic intellectuals cannot interfere with the firm progress of technical logic. The explosion of trains, ships, jets, satellites, mobile phones and the Internet is producing one after another effects. Questioning "fast" is obviously behind the times, including the speed of operation in the field of spiritual consciousness. With the rapid development of transportation in industrial society, the dull mental consciousness has to keep up with the pace. Statistics show that theoretical schools and new concepts have multiplied since the 20th century. The computing speed of human brain is limited, so it can transfer the fast calculation to the machine-it is said that the fastest computer can calculate 54,902 trillion times per second. "Fast" is an irresistible command, whether it is the production of theoretical concepts, the speed of calculation or anything else.

2

The acceleration of industrial society depends largely on machines, and at the same time, machines produce new symbols: images. Since the invention of the camera in 1839, image symbols began to enter life. After the continuous evolution of cameras, projectors, various auxiliary editing and transmitting equipment to the Internet and mobile phones, image symbols have finally developed into a mature ideographic system, and have quietly changed the social and cultural structure with a large area of penetration. Once upon a time, taking pictures was a luxury, and only rich children could own cameras and master this fashionable artistic skill; Subsequent film screening requires more perfect social conditions, and indispensable cinemas and screening equipment as public cultural facilities have won social and financial support. Television began to change this situation. Although TV was once a cultural luxury, this machine soon sneaked into the family as an ordinary household appliance together with refrigerators, microwave ovens and air conditioners.

If the cinema usually stands in the art category, then the TV set is interspersed between the gossip at home or the smell of dishes on the table. Television not only carries movies to the living room of the apartment, but more importantly, it becomes an intimate part of daily culture. There is a strong family atmosphere around the long TV series. Wearing household clothes, sitting on the sofa with a cup of tea in the living room and dressing up for the cinema are two completely different cultural behaviors. Today’s TV programs are more consciously appealing to citizens’ interests. Television not only inserts a large number of advertisements, but also has cooking, shopping, fishing, singing opera and other columns with strong secular flavor. Surprisingly, this small household appliance has completely changed the nightlife of society. After dinner, the number of social workers engaged in poker or mahjong entertainment suddenly decreased a lot, and the chess stalls under the street lamps and the people enjoying the cool chat almost disappeared. Of course, readers of books are also decreasing. Many people have recognized that the image symbols in TV are the most important tool for entertaining.

I believe that most TV practitioners have not estimated that the combination of the Internet and mobile phones will pose such a serious challenge to the TV industry. The challenge follows the successful experience of the TV industry, but it is implemented more thoroughly. The TV in the living room is reduced to a mobile phone in the palm of your hand, and people can choose the programs they watch at will according to their personal schedule and space. Like a dazzling array of supermarkets on the street, many video symbols are stored in major websites for people to choose from. Short video is undoubtedly the most sought-after commodity, and a complete viewing takes only a few minutes or even dozens of seconds; If the content of the short video is worth recommending, you can pass it on to interested people by tapping WeChat on your mobile phone. All the procedures of watching and spreading can be completed in a blink of an eye, which is indeed comparable to the fast pace of life.

Short videos greatly increase people’s visual experience. In ancient society, most of people’s information and knowledge came from written reports. Simple means of transportation limit the radius of life, and the scope of seeing with one’s own eyes is very narrow. For example, how many ancient people have really seen the vast sea or lush virgin forests? Cameras or movie shows open another window of visual experience, and TV really brings great impact. Day after day, TV programs are everywhere, and people can already modify an old saying: what can’t you see if a scholar doesn’t go out? Compared with TV programs, short video narration pays more attention to human beings. If TV cameras tend to capture relatively grand, spectacular and public scenes, then mobile phones that record short videos go deep into every ordinary corner of life and collect all kinds of fireworks. With pictures and truth, a secular, noisy world began to be vividly restored between mobile phone screens.

Perhaps people can perceive a subtle difference: compared with the beautiful words left by the ancients, the image of agricultural civilization in many short videos has shrunk dramatically. The bright moon breeze, the ancient boat crossing, the starry Ping Ye and the fine grass breeze in the Tang and Song poems gradually disappeared, and the "society" in the short video pushed the natural scene to the front desk, occupying the center of the field of vision: streets, communities, shops, traffic, urban buildings, home dining tables and a corner of the campus; Dogs appearing on the screen of mobile phones are mostly family pets, ducks or swans swimming in the artificial lake in the park. Short video was born in modern society, and agricultural civilization is passing by. The generation who recorded short video with mobile phones paid relatively little attention to the image of agricultural civilization. Of course, humanistic intellectuals often evaluate this cultural handover in another sense. In their minds, the gap between short videos and text symbols is not the image of agricultural civilization, but the depth of thought. The warning of humanistic intellectuals is not to alienate or even give up text symbols because of the intuition of image symbols. Up to now, written symbols are still the base camp of human social and cultural classics. The shooting of images can neither express the metaphysical "Tao" nor record the delicate emotional ripples in the heart.

Since the advent of the camera, image symbols have continuously explored their own performance characteristics and rhetorical strategies. The montage of pushing, pulling, leaning, leaning and splitting the lens shows the development history of image symbols. There is no doubt that movies are a collection of various lens languages. The reason why movies can undertake tortuous and complicated narratives is precisely because the image symbols already have a set of expressive ability comparable to the text symbols. Compared with the twists and turns of story statements in movies, the inherent logic of MTV lens language is melody and symbol. Like lyric poetry in written symbols, MTV tries to produce lyrical image symbol organization. However, these explorations are too far away from short videos.

Just like the vulgar spoken language in daily life, short videos only use rough lens language: either call out the mobile phone software for some simple editing, or shoot a shot all the time. The film is surrounded by a separate cultural tribe: famous directors, actors with high prices, staggering investment or box office income, and the refined camera language is the business of this cultural tribe; There is another cultural tribe around TV: those TV reporters with cameras on their shoulders are responsible for shooting all kinds of serious news, and their lens language is authoritative, standard, dignified and lively. In contrast, a variety of short videos record various folk activities, which are lively, vigorous, provocative and humorous; The public acts as both cultural consumers and cultural producers. The economic benefits brought by traffic may be just an unattainable ideal, however, even without economic benefits, it can’t stop the public from getting high. Just as the self-entertainment of karaoke doesn’t care about the singing level, the quality of short video lens language is also insignificant.

Another thing that many people didn’t expect is that such a short video can be watched for so long. The screen of the mobile phone swiped left and right, which consumed the whole morning unconsciously. What did you remember in one morning? Various short videos create kaleidoscope-like fragments mixed together. Some people think that the kaleidoscope-like fragments are just typical feelings of post-modern society. Has postmodernism really arrived? This is not such an important question. I would rather pay attention to the evolution prospect of two tendencies behind short videos: First, the combination of mobile phones, the Internet, video symbols and the public is forming a certain degree of cultural carnival. How to preserve and even inspire the public’s cultural initiative? Secondly, the worries of humanistic intellectuals are not unfounded. Will superficial reading methods lower the cultural level of products and bad money drive out good money? The competition between the two tendencies is not overnight, but involves a long theoretical story pedigree, but a large number of short videos will continue to write a new chapter.

In 1966, American soldiers grabbed the hair of Vietnamese prisoners of war and walked through the jungle.

　　During World War II, American troops mistreated German prisoners of war.

　　In September 1939, Germany raided Poland and World War II broke out. During the war, Germany constantly captured the soldiers of the anti-fascist allies, put these prisoners into concentration camps, and brutally tortured and slaughtered them. People thought that only fascist countries abused prisoners of war, but the United States followed suit.

　　On December 7, 1941, the United States participated in World War II. Five months later, the US military had 32 prisoners of war. More than 20 months later, the number of prisoners of war captured by the United States in France suddenly increased to 48,000. In order to resettle these prisoners of war, the United States began to set up prison camps in its own land, except for leaving some prisoners of war in the prison camps of the warring countries.

　　In 1942, the first prisoners of war were sent to new york. Americans read a letter from President Roosevelt at that time: "You are not prisoners of war here, but guests of the United States." But the president’s promise was never fulfilled. For the captured 6 million German civilians and soldiers, the US military kept them in a giant fence surrounded by barbed wire, which lacked necessary sanitary facilities, and they did not provide sanitary and nutritious food for prisoners of war. During the detention, the US military also inhumanely tortured German prisoners of war. In order to obtain information, the US military often extorts confessions from prisoners of war by torture, beatings and intimidation. What’s more, the US military sometimes fails to provide corresponding medical assistance to German prisoners of war who are injured or sick due to fighting, resulting in more than 10,000 German prisoners of war dying of hunger, cold or disease. There are 380,000 German prisoners of war in the United States. During the war, the US military treated these prisoners with courtesy. However, after the war, the US authorities suddenly changed their attitude, regarded all German prisoners of war as heinous criminals, refused to let them eat enough, and adopted various corporal punishment measures. These prisoners of war were not released after the war, but were "presented" to France to help it rebuild its country. This is against the will of the prisoners of war, who complained during the migration. In the end, 700,000 German prisoners of war were sent to France and put into prison camps. Due to the extreme shortage of food in France after the war and the serious hatred of Germany in France, prisoners of war were tortured by hunger and torture. Many German prisoners of war were flogged and even shot, and at least 1,800 prisoners of war were killed in mine clearance. To this end,The International Red Cross has repeatedly protested to the United States about the unfair treatment of German prisoners of war.

　　Since the United States was an anti-fascist party in World War II, its treatment of prisoners of war was not much condemned by just people and relevant institutions.

People’s Network is a large-scale online information exchange platform built by People’s Daily, a media culture listed company controlled by People’s Daily, and one of the largest comprehensive online media on the Internet. On January 1, 1997, People’s Daily Online was officially launched. On July 1st, 2006, the Central Committee of the Communist Party of China approved the launch of "China communist party News Network" hosted by People’s Daily, and became an authoritative website to publicize and introduce the Communist Party of China (CPC)’s thoughts, theories, policies and information.

Weilai Automobile provides users with a convenient charging solution, and the service fee for battery replacement by code scanning is 180 yuan every time, which is consistent with the one-click start-up service.

Weilai has always been committed to improving the experience of car owners. As a car owner, you can enjoy the privilege of replacing Weilai battery for free for life on the basis of enjoying the lifetime free warranty service of your car. This policy covers all non-first-time car owners, and the battery replacement cost of operating vehicles consists of battery replacement cost plus electricity and service charges.

Specifically, the electricity price and service charge at the place where the power exchange station is located may be slightly higher than those at the surrounding operation sites. On July 7, 2020, Weilai launched a new power exchange mode for non-first-time car owners and operating vehicles, in which the power exchange cost includes battery cost (135 yuan) and service fee, and this policy will take effect on July 10. For users who buy new ES8, ES6 and EC6, they can enjoy the right of free power exchange for life.

Weilai provides car owners with flexible battery selection. Users can choose battery packs with different capacities according to their needs, and users of standard battery packs can get compensation, such as 200 credit days, when changing power across levels. The excellent performance and battery technology of Weilai ES6 ensure that users can enjoy long battery life without worrying about battery performance attenuation.
