HOLA~ "Traveling with Movies"

Argentina’s third stop — Indulge in Argentina’s hot tango

　 　 In the third stop of "Traveling with Movies", let’s explore the hot and unrestrained side of Argentina by stepping on the jumping dance point and following the elegant skirt and enchanting dance steps ~

【The purest tango, performing a tango madness.】

Tango mania

Director: Carlos Saura
　Screenwriter: carlos saura
　 　 　 　Starring: Miguel Angel Sola/Cecilia Narova/Mía Maestro/　

Juan Carlos Copes/Carlos Rivaro
　 　 　 　Type: Drama/Song and Dance
　 　 　 　 　 　 　 　Producer country/region: Spain/Argentina
　 　 　 　Language: Spanish

　 　 Song and dance have been endowed with new magic under the lens of carlos saura. Under the tutelage of bunuel, she has successively won international A-level film festivals such as Berlin, Cannes, Golden Globe and Laffargue Sebastien, and has been nominated for the Oscar Award for Best Foreign Language Film. She is a third-generation Spanish national treasure director. His name represents a generation of movie master, and his musicals symbolize the peak form of this art.

　 　 The director used dance, lighting and scriptwriting skills to form a wonderful audio-visual feast. carlos saura gave the tango a sense of ceremony. The film weaves the actors’ realistic state with the feelings in the play in the form of play, making the whole film not only a musical and a feature film, but also a unique artistic form of carlos saura, so romantic and exquisite.

　 　 Tango is a beautiful sadness in Argentina. It is a proud sadness and an unbridled love. carlos saura perfectly shows this art with his own lens. The tango of the three people in the film has become the most amazing part of the film, the temptation, the passion, the struggle of love and being loved, and the trick of fate. It seems that there is only one art in the world that can express such passionate love.

　 　 Carlos saura is a well-deserved master of musical films, and his films have reached the highest level of art films, regardless of the use of colors, the setting of scripts and obscure metaphors. Only art can understand tango, and only carlos saura can understand tango.

Tango is the national dance of Argentina. For Argentines, dancing tango is as simple as eating a meal, which is basically two glasses of red wine, and two people can dance together with each other by virtue of the tacit understanding — —

　 　 Argentine tango is also called "dance between legs". The two dancers cling to each other like warm babies, and their legs show dance movements in the form of "kicking, winding, winding and hooking", which makes people see things in a blur — —

　 　 Different from the international tango, the Argentine tango has no rules, and all the steps are improvisational freestyle. Everything is based on the tacit understanding between the two dancers, so the Argentine tango is also called "the dance that can directly touch the soul".

　 　 In the minds of Argentines, tango has already surpassed the existence of dance. Tango is a kind of culture and a way of life. Without the company of tango, life seems dull and the soul always feels empty.

Tango — — Square dance of Argentine people

Scent of a Woman.

Director: Martin Brest
　 　 　 　Screenwriter: bo goodman/Giovanni Arpino
　 　 　 　Starring: Al Pacino/Chris O’Donnell　
　 　 　 　Type: plot
　 　Producer country/region: USA

　 　 From a unique perspective, it tells the story of youth, the confusion of two generations and the pursuit of the meaning of life. Al Pacino’s role in it has become another classic that can’t be copied.

　 　 Al Pacino, who is blind in the film, is so selfless and confident when he dances the tango. He danced not only a dance, but also the unremitting pursuit of a better life. This is exactly where this movie attracts the audience. Al Pacino is blind, but his world is extremely bright. This is an alternative romance and a very tense performance.

　 　 The film tango is intoxicating. This is the power of this dance, and this is the power of the film. Movies give this beautiful art a second life. The audience listened to the dance music, and through the dance steps, they watched all the love, met, met, knew each other and stayed together.

　 　 A famous Hollywood screenwriter once questioned how the poor scriptwriting skills of this film could be regarded as a classic by the audience. In fact, the screenwriter is right. The contradiction of the main line of the film can’t hold up the whole film at all, and some details of the plot need to be examined. But this kind of film is to create a feeling, and fans hope for the feeling realized in the film, without so many designs and skills. Sometimes simplicity can touch the softest part of people’s hearts. This is the only way for movies, and so is life.

有些人一分钟内过尽一生，我愿意用一生等待我的舞伴

　 　 影片中阿尔·帕西诺伴着阿根廷经典舞曲《只差一步》，舞出了影视上最美的一段探戈。在探戈中，舞曲就像是一味强心剂，将舞蹈的氛围上升到了另一层高度。

　 　 在阿根廷，就有这样一位“探戈之父”卡洛斯·葛戴尔，他创作出的探戈舞曲将无数舞蹈推向高潮，是当之无愧的阿根廷探戈的象征——

卡洛斯·葛戴尔 1890年12月11日-1935年6月24日

　 　 虽然卡洛斯早已经离开我们，但是以他名字命名的探戈剧院——EsquinaCarlos Gardel绝对是欣赏纯正探戈的好去处——

　 　 这里是卡洛斯生前生活和创作作品的地方，周围建造着卡洛斯博物馆和主题咖啡馆来怀念他，但是最值得一去的还是金碧辉煌的EsquinaCarlos Gardel。

　 　 EsquinaCarlos Gardel本是一家餐厅，但是由于有一个探戈舞台，再加上现代化的灯光舞美，让这里成了欣赏探戈舞的好去处。

　 　 由于这里是为了纪念卡洛斯而建，所以演出曲目都是较为经典的舞曲，更多的是为了重现卡洛斯的辉煌——

　 　 In addition to enjoying the classic tango performance, you can also taste good red wine and various barbecues here (after all, people are also a restaurant here). The restaurant provides three fixed dishes, and fat friends can choose according to their personal preferences ~

　 　 Of course, for a better look and feel, I recommend you to book online in advance, not only to book a better booth, but also to get a discount price ~

【A tango is a carnival of Hong Kong movies.】

once a thief

Director: John Woo
　 　 　 　Screenwriter: John Woo/Gao Zhisen/Janet Chun
　 　 　 　Starring: Chow Yun Fat/Leslie Cheung/Cherie Chung/　
　 　 　 　Genre: drama/comedy/action/crime
　 　 　 　 　 　 　 　Producer country/region: Hong Kong
　 　 　 　Language: Cantonese/English/Hakka/French

　 　 Hong Kong movies in the 1990s are the most beautiful night sky in the hearts of fans, and they are definitely the brightest stars in the night sky. Leslie Cheung, Chow Yun Fat and Cherie Chung formed the most classic threesome in Hong Kong film history, and a tango in the film also became an eternal classic in film and television.

　 　 John Woo put down his dove, cloak and double guns, and poured romanticism into the whole film. In the film, Leslie Cheung and Cherie Chung danced tango, which made fans unforgettable. The pace of tango dance is seamless with the editing of "stealing techniques". Cherie Chung dances beautifully, and Leslie Cheung dances a charming son.

　 　 The two dancers in the tango dance can’t smile, but John Woo handled his own tango dance, and the design of the two has always been smiling, which perfectly fits the romanticism of the film. Will be a thrilling action task, the clouds are weak and the wind is rising. John Woo subverted the meaning of the original gangster film in Hong Kong with his best romanticism.

　 　 How chic and fast "Across the Seas" is, only the combination of these three people can interpret this detachment and freedom, and only John Woo can truly travel around the world in the film industry.

　 　 The dance in the film seems to epitomize the whole carnival era in Hong Kong. This is a memory engraved in the hearts of fans, which can’t be forgotten to be true, but you can recreate this classic with your own dance steps.

　 　 In the Boca neighborhood of Buenos Aires, you can always dance a graceful tango with your partner, no matter whether you are a professional dancer or not — —

　 　 Caminito street in Boca district is a perfect interpretation of what life is a stage everywhere. It is a mixed slum in Buenos Aires and the birthplace of tango. The whole street is full of bars, restaurants and souvenir shops, and the most important thing is that street artists and tango dancers are hidden in every corner — —

　 　 Put on your best-looking skirt, pick one of the street dancers with an eye, give him a wink, and he will come to you and invite you to dance — —

　 　 It doesn’t matter if you don’t have a dance foundation. You can safely give yourself to your partner, let Ta take you around and jump, and then make eyes at Leslie Cheung Cherie Chung from time to time, as if you had a three-minute love affair with a stranger ~

　 　 Of course, you can also give the dancers a little more labor, and let Ta take you to unlock more new poses ~

　【If you invite me, I would like to respond with a tango.　】

[Talking about Love, Dancing] (2004)

Director: Peter Chelsom

Screenwriter: audrey wells/Masayuki Suo
Starring: richard gere/jennifer lopez/

　Susan sarandon/Stanley Tucci/richard jenkins
Genre: drama/comedy/love
Producer country/region: USA
Language: English

　 　 If the Japanese version of Shall We Dance focuses on "talking about love", then the Hollywood adaptation focuses on "dancing".

　 　 The hero who suffered a midlife crisis began to learn to dance because of his admiration for the dance teacher and finally fell in love with it, saving himself and his friends at the same time. An inspirational and warm story, the Japanese version handled it delicately and moving.

Office waltz

A soul dancer who relies entirely on Yan Yi

The most embarrassing scene in the whole film is actually very touching.

　 　 Uncle who learns to dance secretly, Latin man who can liberate his nature by wearing wig, proud and coquettish aunt, etc. In Japan, a rigid society that emphasizes collective weakening of personality, the stories of these deviant little people are sad and touching.

　 　 In the American adaptation, the tension of these cultures is missing. In the American society that emphasizes individuality and freedom, modern dance has a deeper soil, which makes the copied story seem unreasonable. There is no "talking about love", but only "dancing".

The most beautiful scene in the whole film

　 　 Interestingly, the Japanese version covers almost all modern dances, but never tango. In the American version, when the hero first came to the dance classroom, the dance teacher shouted, but it was "TANGO".

　 　 Perhaps in the reserved Japanese culture, the passionate and heroic tango seems to go too far after all. In the free and unrestrained American culture, only the tango, the "dance between lovers", can interpret this secret feeling.

　 　　

　 　 The most wonderful passage in the American version is a tango between the dance teacher and the hero. In the warm yellow and ambiguous light, accompanied by lively and strong music, men and women are like a pair of soldiers who go to love, teasing and competing with each other. A serious expression is the best disguise, the aroused calf is a secret desire, the rotating skirt is a silent invitation, and the dumped body is a gesture of submission. A tango will pour out all kinds of customs.

　 　 Both versions of the film describe the protagonist’s participation in the dance competition. Of course, in real life, if you want to take part in the tango competition and try the water, then you must not miss the Argentine International Tango World Championships, a global tango feast ~ ~ ~

Competition site

　 　 Speaking of the Tango World Championships, we can’t help but mention the USINA Art Center in Argentina, which was formerly the castle of the power company, and was later abandoned and transformed into an art center, becoming the official fixed place of previous Tango World Championships — —

USINA art center former site

　 　 As an art center, the most creative thing in USINA is the 70-degree mirror. There is a European-style wall on the ground, and a big mirror is inclined at a 70-degree angle with the wall. People lying on the wall can just show the effect of handstand in the mirror, which looks very cool — —

　 　 Many people have experienced the pleasure of climbing over the eaves here — —

　 　 No dance can be so hot and dazzling. Every dance step is full of temptation and passion. Tango is not only a bold expression of love, but also an attitude towards life, for all the good and love.

　 　 Caesar built his empire in eight years, and it only takes you three minutes to conquer everyone with a tango.

　　[Dialogue of Guangming International Forum]

　　Original title:Where does the economic recovery and development after the epidemic come from?

　　The management of "isolated" companies divorced from industrial chain information is extremely unreliable.

　　Lu Lijian: After the outbreak of the COVID-19 epidemic, leaders and industry experts in various countries gradually realized the importance of industrial chain management and studied measures to improve the stability and competitiveness of the industrial chain. As leading scholars in the field of industrial chain management and digital economy, Professor Federgren and Professor Maglas, can you introduce the development history of industrial chain management from a professional perspective and how to see the impact of the epidemic on the world economy?

　　Lu Lijian: Professor of Business School of Hong Kong University of Science and Technology, winner of the Nicholson Award of the International Institute of Operations and Management, and former global vice president of quantitative investment of Goldman Sachs Group.

　　Federgren:Industrial chain management is very popular now, and high-quality enterprises with core competitiveness have a very professional and perfect industrial chain management system. But 20 years ago, this major was almost a niche discipline. Only the analysts and middle managers of the expert team were concerned about the difficult problems in the design and management of the high-efficiency industrial chain, and these problems rarely even appeared in the company’s board of directors or government cabinet meetings. Even similar business administration majors in business schools rarely offer related courses or only a few students are interested in such courses.

　　Awi Federgruen: Charles Professor at Columbia University Business School, head of the Department of Risk Decision-making and Operation Management, and academician of the American Academy of Engineering.

　　Nowadays, this phenomenon has changed dramatically. On the one hand, because of the crisis caused by the COVID-19 epidemic, many countries realized that the key elements of products were seriously inadequate overnight, and the news media kept reporting the serious shortage of medical materials. In addition, the grounding order and factory closures around the world have caused serious deficiencies in other key elements of the product line unrelated to the epidemic. For example, Procter & Gamble, the world’s top 500 company, is a manufacturer of household products such as laundry detergent and toilet paper. More than 9,000 kinds of raw materials needed to produce 17,600 kinds of finished products depend heavily on more than 400 different suppliers in China, and its first-line suppliers in other countries are also facing a shortage of raw materials. The serious shortage of core key production factors like this makes enterprise managers and economic policy makers realize that the traditional "isolated" corporate management mechanism that is divorced from the upstream and downstream information of the industrial chain in which the company is located is extremely unreliable. For the sustainable, healthy and stable development of the economy, we must reshape the stability and competitiveness of the industrial chain from the perspective of the industrial chain.

　　According to a survey conducted by the American Supply Chain Management Association at the end of February and the beginning of March 2020, about 75% of the companies reported that the COVID-19 epidemic caused the interruption of their industrial chains, and 44% of the companies did not have any plans to deal with such interruption risks. Among Google’s 2.5 trillion global search keywords throughout the year, the frequency of the word "supply chain" has increased fivefold from early January to mid-April 2020.

　　In fact, industrial chain management, as the core part of the company’s strategy and the core driving force of the company’s profitability, existed long before the COVID-19 outbreak, and will continue to exist in the future. Some industries have been completely changed because of the innovation of industrial chain strategy. For example, Amazon can lead and monopolize the global electronic retail industry, not because it provides better or different products, nor because its price is more competitive than its competitors. Its unprecedented success is only because of its innovation in industrial chain management strategy. For the same reason, Wal-Mart has nearly $517 billion in global revenue. Wal-Mart is by far the largest comprehensive retailer of physical stores and e-commerce in the world.

　　Maglas:The COVID-19 epidemic has brought great loss of life, economic interruption and uncertainty. The global health care system, political system, the ability of relevant institutions to respond to the crisis, and the economic relevance and dependence through the convergence of global industrial chains are facing severe challenges from the epidemic. In addition, the epidemic has aroused great concern about social injustice, especially among some people who have health and economic income crises caused by the epidemic.

　　Costis Maglaras: Dean of Business School of Columbia University and Professor of David and Lynn hilfing.

　　Many of us have been involved in a natural experiment for nearly a year. After the outbreak of the epidemic, many countries implemented the isolation policy of closing cities and homes, and some countries are still studying and working remotely. Although some industries, such as food and agriculture, have not stopped operating during this period and have returned to normal operation to a large extent, a large number of economies related to service industries will continue to work remotely. Such a situation has accelerated the trend that appeared before, and has produced a butterfly effect on urban transportation, working methods, workplace, shopping methods, service methods, reading methods and supply and demand.

　　Lu Lijian: That’s true. The China government has done an excellent job in controlling the epidemic, and the epidemic has been effectively controlled at home. I found that the word "industrial chain" or "supply chain" has a frequency of nearly 100 million in China. The impact of this epidemic on the world economy is extremely great. Taking the United States as an example, the epidemic caused a large number of enterprises to go bankrupt, involving a wide range. The traditional service industries such as transportation, catering, hotels and tourism were the most affected, followed by industrial enterprises, especially manufacturing.

　　The globalization of industrial chain is related to the safe production capacity.

　　Lu Lijian: The industrial chain in the 21st century is closely related to economic globalization. After the outbreak of the epidemic, the media in individual countries hyped the topic of "anti-globalization" and proposed to stop globalization and let manufacturing return to their own countries. Even some politicians in individual countries regarded globalization as a political game and chip. What does Professor Federgren think of the phenomenon of "anti-globalization"?

　　Federgren:A key strategic question is, from the perspective of efficiency and flexibility of industrial chain, does a company need to localize suppliers, or outsource to other countries or regions, or use both internationally? In the past few decades, an obvious practice in the United States or most European countries is to gradually outsource manufacturing to countries and regions where labor and raw materials are cheaper. Recently, we have also seen the momentum contrary to this. For example, between 2000 and 2003, 240,000 manufacturing activities were outsourced to areas outside the United States every year. However, this figure was reduced to 50,000 in 2016. In the same year, 70,000 similar manufacturing activities were brought back to the United States, and the direct impact was to increase and promote job opportunities in the manufacturing industry in the United States. Before the COVID-19 epidemic spread, the new information provided by Bank of America confirmed this phenomenon. In a survey involving 3,000 companies, the researchers found that in 12 global industries with a total market value of more than 22 trillion US dollars, more than 80% companies located in North America, Europe and Asia except China are implementing or announcing plans to move back to the United States from their current regions, which shows that the localization trend does exist.

　　This is a container photographed in Banrang Port Area, Brazil, Singapore on August 17th, 2020. Xinhua news agency

　　So how to explain this trend against globalization? First of all, the company realizes that the selection of suppliers should not only depend on the direct production costs of purchasers, but also take into account the total landing costs of all costs associated with suppliers, including transportation, warehousing and customs costs, as well as the costs needed for safe inventory to meet local needs. The costs associated with these inventories can be enormous, especially when the distance from suppliers to the local area is very long, full of uncertainty and the need to maintain high quality of service. In addition, suppliers usually have capacity constraints, and their capacity varies greatly. Secondly, the increasing risks of the global economy have prompted companies to constantly change their supplier selection decisions and corresponding procurement strategies. In the past 40 years, the cost of production labor in some countries has also been increasing. In the current trade friction, the United States, China and Europe are rapidly changing their trade tariffs, which makes the fluctuation of logistics costs and commodity prices constantly increase. In addition, foreign exchange and interest rates are constantly changing rapidly. All these fluctuations have an important impact on demand, cost and production capacity. Generally speaking, due to sudden supplier closure, quality problems, rational distribution plan and other factors, the theoretical capacity level is very different from the actual production process. Thirdly, due to the limitation of suppliers’ production capacity, it is necessary to purchase from two or more suppliers in a volatile environment.Even what companies are eager for. Of course, the difficulty of the global purchasing strategy of multiple suppliers is how to decide the allocation problem of each supplier and how to dynamically adjust the allocation decision between suppliers by using inventory information. In most cases, enterprises can use contracts similar to the concept of financial options to solve the problem of supplier allocation, that is, enterprises can book or invest in the capacity of suppliers in advance to ensure that they have the corresponding capacity when needed in the future. Similarly, for a multinational company with two or more assembly plants distributed in different regions of the world, and the cost and delivery cycle of these factories to serve customers are different, it faces the same dilemma.

　　Lu Lijian: You returned to the objective law of economic development from the dimensions of total economic landing cost, economic risk and production capacity, and expounded the "anti-globalization" that appeared in recent years. Your analysis makes people understand the truth that whether an enterprise implements globalization strategy is determined by the efficiency and flexibility of the industrial chain of its product production. Indeed, the globalization of industrial chain is the objective requirement of the development of social productive forces and the inevitable result of scientific and technological progress. It does not plague economic development as some politicians and media say. Their purpose is to "politicize" the issue of globalization. In your opinion, how to improve the flexibility and competitiveness of the industrial chain in the post-epidemic era?

　　Federgren:In most industrial chain configurations, the volatility level or risk level is the primary driving force for high operating costs. Under the global production and procurement system with multiple suppliers, due to the full and effective sharing of orders and capacity resources among suppliers, the industrial chain system has enhanced its ability to resist risks, thus having higher flexibility and operational efficiency. Therefore, the globalization of industrial chain is an important measure to improve the production capacity with safety guarantee.

　　In addition, we should also consider that the supplier’s channel is in a state of partial or complete interruption during the epidemic. The COVID-19 epidemic has produced a large number of actual cases as described above. However, the problem is not limited to the once-in-a-century COVID-19 epidemic. Other factors, such as the flood disaster in Thailand, the earthquake in Japan, the hurricane similar to Katrina in the United States, local fires and factory pollution, will also cause worldwide production and supply disruptions. In the vaccine manufacturing industry, due to the small number of international suppliers and the frequent long-term closure of production equipment, the problem of insufficient production capacity has always existed. Therefore, the consideration of industrial chain flexibility also provides additional incentives for multi-supplier global supply strategy.

　　In fact, my team’s latest research shows that compared with the procurement strategy of a single supplier, the benefits brought by the procurement strategy of multiple suppliers, even if only two suppliers, are very obvious. Even in an environment with stable cost, stable demand and risk-free production capacity, the benefits of global decentralized procurement are also very significant. Of course, in a volatile market environment, the effect of decentralized global multi-supplier configuration will be more obvious. However, to realize and realize the benefits brought by globalization requires the most advanced industrial chain configuration models and algorithms, and these studies are also the focus of my research team at Columbia University Business School.

　　Lu Lijian: From the perspective of reducing the fluctuation level of the industrial chain, you discussed how to rationally use the procurement decentralization and incentive mechanism in the process of globalization to effectively improve the efficiency of the industrial chain and reduce the fluctuation. From the perspective of historical development, economic globalization has promoted the flow of goods and capital, the progress of science and technology and civilization, and the exchanges between people of various countries, providing a strong impetus for world economic growth. Of course, economic globalization will not be smooth sailing, it is a double-edged sword, and there will be various problems, such as geopolitical risks, high dependence on production links in a certain region caused by high concentration of suppliers, and insufficient response ability to abnormal demand. However, simply blaming the problems that plague the world on economic globalization is neither in line with the facts nor helpful to solve the problems. In the face of opportunities and challenges, it is more important to ease trade frictions, remove barriers to enterprise development, work closely together to cope with all difficulties and challenges, work together to achieve comprehensive economic recovery and healthy development, and advocate formulating strategies according to local conditions to enhance the flexibility and core competitiveness of the industrial chain.

　　Technological innovation is an important driving force for economic recovery and development.

　　Lu Lijian: In recent years, technological innovation including big data technology has developed rapidly and been widely used, playing an increasingly important role. Professor Maglas, please talk about the application of this technology in service and digital economy and its significance to economic development in the post-epidemic era.

　　On October 28, 2020, in Sejong City, South Korea, the staff showed an auxiliary distribution robot that could follow the courier’s movement. Xinhua news agency

　　Maglas:Although the COVID-19 epidemic has caused great losses to the world economy, it has also accelerated technological innovation in many fields, which is an important driving force for economic recovery and development.

　　First of all, in the field of transportation, all kinds of enterprises are trying to overcome the problems encountered in the resumption of production and work caused by the COVID-19 epidemic, set a safe social distance, and formulate detailed rules that people should abide by in the halls, elevators and open office environments of commercial buildings. In the city business center, the problem of employees commuting safely is particularly worrying, because it is a process that relies heavily on the public transportation system. At present, the public health policy requires to reduce the congestion of the transportation system and increase the utilization rate of bicycles. However, this model is not enough to meet the transportation needs of millions of commuters on a large scale, especially for long-distance commuting. For example, in the urban subway transportation system, assuming that the safe distance between people is doubled, for example, from 2 feet to 4 feet, the traffic capacity will be reduced to 75%. This requirement has a particularly serious impact on peak hours. The safe social distance during peak hours is usually close to 1 foot, and the requirement of increasing the social distance to 4 feet will reduce the transportation capacity to only 5%.

　　So how to deal with the extremely shrinking traffic capacity caused by the epidemic? Here, I will focus on analyzing and expounding the principle of demand smoothing in management, that is, the idea of reasonably dispersing demand throughout the time interval. Managing an economic society in a special period of gradual resumption of work and production forces us to rethink the most basic assumption in daily life, that is, most people have the same working hours and need to take the public transport system at the same time every day. This basic assumption can and should be removed, for example, by staggering the working hours in some way. This process of smoothing demand and reducing the load utilization rate during peak hours will greatly reduce the congestion of public transportation systems, road networks and office buildings. For example, assuming that the current system has a 60-minute peak period and a 90-minute busy period every four hours, a simple calculation shows that a subway will improve its transportation capacity by more than 30% and maintain its operation at a utilization rate below 85%. Considering different traffic networks, only the way of smoothing demand will make up for 50% of the loss of traffic capacity caused by the increase of social distance during the epidemic, and increase the traffic capacity in the post-epidemic era by 30%. In addition, it will reduce the congestion delay and total traffic time caused by full subway cars and crowded platforms.

　　The method of demand smoothing is also being applied in the road system, aviation and power network system in the United States. Generally speaking, such smoothing can be achieved through price incentives, such as giving a certain discount on electricity consumption at night, and charging higher fees for driving in special areas during peak hours. However, before shifting to price incentives, we should try to reduce the structural impact of the convergence of daytime working hours on the peak infrastructure load. Car sharing is another feasible solution to traffic congestion. In order to promote the use of shared cars, we need to invest in the optimization of technical schemes such as scheduling and pricing mechanism. At present, many difficult problems in the field of shared cars will lead to more in-depth thinking and guide a large number of sustainable technological innovations.

　　The second area is telecommuting. After the outbreak, almost all employees switched to telecommuting overnight, which greatly affected the service industry and my higher education. Many people are studying such a topic: to what extent the emergence of telecommuting will be a long-term trend, and what kind of science and technology and management tools can be used to create an inclusive, innovative and dynamic organic culture. Although telecommuting has achieved great success during the epidemic, it is still uncertain whether this method can be successful for a long time. In the current environment, telecommuting is facing great difficulties and challenges. For example, it is very complicated to hire and train new employees, and the process of innovation requires intense and purposeful joint research and development, which are difficult to achieve by telecommuting; Corporate culture is also difficult to maintain and evolve through telecommuting, and personal relationship networks usually rely on spontaneous and informal communication — — It is almost impossible for "cold water communication" in remote mode to replace it. Most people may rely on scientific and technological tools for projects, documents and other work, or work together through online meetings, but these tools can’t solve the problems and challenges in interpersonal communication mentioned above.

　　In order to fill this defect of telecommuting and cope with the current epidemic crisis, many very meaningful innovations are currently under way. For example, some innovative works combine the virtual network and virtual reality technology that are currently being created. A large part of this work draws on the knowledge and technology of online game industry. It is a very necessary measure to improve our ability to maintain close relationship and virtual communication. In addition, how to fully combine offline communication to achieve the best results also requires in-depth thinking and guidance from team and project management.

　　Finally, innovation also plays an important role in the recovery of other service industries. Education has been transformed during the epidemic, and the experience we have quickly explored and learned will continue to play a role. The scientific and technological tools of distance learning will allow scientific research institutions to provide online and offline hybrid teaching methods, focusing on interpersonal interaction activities that can be most beneficial to students’ learning, and enhancing the value of the educational projects we provide. In addition, we can quickly get familiar with and use distance education tools, and then improve the education level in remote and poor areas lacking teachers or professional educators.

　　In a word, the epidemic has brought about great changes in many aspects of our economy, forcing us to rethink and rethink many aspects and habits of life. This process is subversive, but it will continue to lead long-term innovation and changes to our global economy.

　　Lu Lijian: You discussed the important role of technological innovation in economy. Search, socialization, payment and entertainment constitute the infrastructure of the online world, and the digital and intelligent upgrading of the industrial chain is also the infrastructure for building the future data productivity era. After adopting digital technology, industrial chain enterprises are not only an individual in the economic sense, but also a source of data production, and these industrial chain data are of extraordinary significance for Industry 4.0, intelligent manufacturing and the possible AI+ manufacturing revolution in the future. In the post-epidemic era, technologies such as big data, artificial intelligence and blockchain will play a more important role in the industrial chain. First of all, through the decentralized, open, autonomous, anonymous and tamper-proof characteristics of blockchain, problems such as data leakage, theft of sensitive information and geopolitical interference have been effectively solved. Secondly, because data can objectively reflect the truth and development law, rich and comprehensive data greatly improve the geographical limitations in the process of traditional globalization, increase the efficiency of information communication and accurately trace the source of problems. This kind of big data technology helps to reduce the cost and obstacles of information communication in the industrial chain and greatly improve the efficiency and competitiveness of the industrial chain. In the future digital era, whoever has the most comprehensive data volume and has mastered intelligent technologies related to big data processing and business analysis will have the core competitiveness of this market.

　　Guangming Daily (January 23, 2021, 08 edition)

　　Beijing, March 11 (Reporter Song Yuxi) On March 10, the art test of the School of Performance of Beijing Film Academy entered the third test. According to the rough calculation of the three-test list of the 2018 Art Test of the Performance Academy published by the Beijing Film Academy, more than 300 people entered the three-test. In addition, the reporter also learned that, unlike in the past, there will be four more tests in the art test of the Beijing Film Performing Arts Institute this year, and the examiner will examine the candidates from three aspects: image temperament, ideological morality and cultural literacy.

　　The number of three tests is basically the same as last year.

　　On the same day, the reporter saw in the "posting place" of Beiying that many majors have successively entered the stage of re-examination and three trials. The performance academy, which has attracted much attention, has posted three test lists.

　　According to the reporter’s rough calculation, more than 300 people entered the third test, and the number was basically the same as last year. This year, the number of applicants for the North Film Performing Arts Academy reached 9,693, and only 50 people are planned to be enrolled.

　　The reporter learned that the three tests are comprehensive examinations, and the test questions are randomly selected by the examiner on the spot, so that candidates can fully display their artistic talents.

　　It is worth mentioning that it is reported that Landy Li and Hu Xianxu, who have appeared in many film and television works before, also appeared in the examination room of Beijing Film Third Test.

　　Add four tests: we will examine ideology, morality and cultural accomplishment.

　　Different from the past, this year, the Beijing Film Performing Arts Academy has added four tests. It is reported that the four tests added this year are interviews, and the examiner will inspect the candidates from three aspects: image temperament, ideology and morality, and cultural literacy.

　　Professor Zhang Hui, Dean of the North Film Performing Arts Institute, introduced that the whole performance entrance examination was recorded, which made all-round supervision for candidates and examiners. Examiners are strictly screened and randomly selected by the school. In addition to our teachers, 1/4 examiners are invited experts.

　　He said that the examination room and examination time of candidates are decided by lottery. Candidates only report serial numbers, not names, and examiners do not communicate with each other and score back to back. Removing a highest score and a lowest score is the candidate’s final score. The results of the initial test are not included in the second test, and the results of the second test are not included in the third test. The third test is a comprehensive test, and the final score of the candidates is obtained by adding the average scores of all examiners.

　　Cosmetic surgery and make-up become hot topics in art examination.

　　For the candidates who apply for the performance major, the topic related to "Yan value" will always become a hot topic during the art test.

　　This year is no exception. When Ma Yili was previously the examiner of the Shangxi Art Examination, the expression of rejecting the candidates of cosmetic art once again attracted the attention of netizens. On the 10th, this interview was on the hot search list of Weibo, and it was once the top spot.

　　In fact, this year, many colleges and universities such as Chinese opera and Shanyi said no to cosmetic candidates. For plastic surgery students, the leaders of Beijing Film School have indicated at the beginning of this year’s art examination that the school will definitely implement it in strict accordance with the requirements of the enrollment brochure.

　　Not only that, the North Film Trials, which started on the 10th, also had "zero tolerance" for the makeup of performance candidates.

　　The reporter saw that there are six instructions for the candidates of the third entrance examination of the North Film Performance Academy, two of which are related to the candidates’ clothes and makeup. It requires that "all candidates are forbidden to wear make-up, Cosmetic Contact Lenses and turtleneck tops", and it also stipulates that "candidates who take part in the third test must wear professional training, tight-fitting sportswear and special training flat shoes for dancing".

　　In this regard, some candidates said in an interview with reporters that "since there are requirements, you will definitely not wear makeup" and "the exam should let the teacher see the true self". (End)

　　On the 24th, the topic #15-year-old girl lost only 24.8kg and died # made netizens cry. Xiaoling (pseudonym), a girl, developed from dieting to losing weight into anorexia nervosa, and eventually lost her life because of severe malnutrition, respiratory failure and deep coma.

　　The sadness behind the first hot search … …

　　The doctor was shocked when he took the CT scan: it was as light as lifting a quilt.

　　One afternoon in March, the transfer center of Shenzhen Children’s Hospital received help from a hospital in Dongguan. Xiaoling (pseudonym), a 15-year-old girl, was severely malnourished and had respiratory failure, and she had lost consciousness.

　　Xiaoling’s father, who was transferred to the hospital with the car, told the doctor that Xiaoling had not eaten anything for nearly 50 days since the third day of the new year, only drinking water. I was delirious at home last week and was rushed to hospital.

　　Xiaoling is 165 cm tall and weighs only 24.8 kg. This weight is not even as good as that of some junior children.

　　The doctor looked at Xiaoling carefully, but she didn’t breathe spontaneously at all, and her mouth was bleeding all the time. The biggest problem is that Xiaoling’s pupils are unequal and her reflection on light disappears. "This is a very bad signal", the pupil is controlled by the brain stem, and the pupil is unresponsive, which means that the brain stem has been damaged and may not wake up.

　　After Xiaoling was transferred to Shenzhen Children’s Hospital, she was immediately pushed to take a CT scan of her brain. As soon as the doctor passed, she was shocked: It’s so light, it feels like lifting a quilt.

　　So thin, it’s really skin and bones. So that when I went to bed, the doctor repeatedly told me to be careful, slow down, and especially be careful of fractures.

　　Girls lose weight for love at first.

　　Mom recalled that Xiaoling was the fattest when she was in the sixth grade, about 104 kg. When she entered junior high school, her family found that she was "conscious of losing weight". "She told us that she didn’t eat with oil, not at all."

　　Mom said that according to classmates, Xiaoling has a crush on a boy, but that boy likes a girl thinner than her.

　　Later, there was another "pusher" on the road to losing weight: the psychology of comparison. Once, Xiaoling saw another girl in the class eating only vegetables and decided that she was losing weight. Xiaoling can’t accept the fact that I am more beautiful than that classmate and have better grades than her, but she is thinner than me!

　　Slowly, Xiaoling didn’t eat rice and staple food, and finally she didn’t eat at all but drank water. Dieting turned into a hunger strike.

　　In the next year and a half, Xiaoling repeatedly fasted until she fell into a coma and her life was dying. When she was transferred to a hospital in Dongguan, her grandmother, who had brought her up in one hand, cried her heart out and refused to let her granddaughter get on the ambulance: "Don’t send her away, don’t let her die outside." This situation has made many people cry.

　　Why did parents not intervene in advance?

　　In fact, Xiaoling’s parents forced her to go to the hospital many times, but the first time she went to Xiaoling, she tried to jump out of the car and opened the door four or five times. When she arrived at the hospital, Xiaoling was forcibly dragged into the ward, so she hit her head with a shower and tried to jump out of the window … …

　　There is another reason why parents are helpless. Xiaoling has anorexia nervosa, which is what we often hear. This disease is one of the mental diseases with the highest mortality rate, and even psychiatrists have to smell it.

　　At first, Xiaoling’s father found many pictures of anorexia on the Internet to show her. "If you go on like this, you will get anorexia." But Xiaoling vowed: "Dad, don’t worry, I won’t get anorexia."

　　After losing weight for one year and three months, Xiaoling found that she didn’t have her period and was taken to Shenzhen Children’s Hospital for examination by her parents. She was diagnosed as anorexia nervosa.

　　Xiaoling’s mother said: "At first, she wanted to reduce her weight to more than 50 kilograms, but when she reached her fifties and sixties, she had no bottom line and only became thinner and thinner."

　　Before being sent to hospital, he had suffered from 14 diseases.

　　Before Xiaoling was transferred to Shenzhen Children’s Hospital, there were 14 kinds of diseases in her body, all organs in her body were damaged or even failed, and her brain might never wake up.

　　Xiaoling didn’t wake up at last. When the doctor told the parents "I tried my best to make a choice", my father choked: "I can’t bear to give up."

　　After much consideration, my parents decided to let go, and finally my mother accompanied Xiaoling through the last journey … …

　　After Xiaoling’s story boarded the hot search, it triggered a discussion among netizens.

　　Some netizens said that health is the most important thing; More netizens feel that society should advocate healthy aesthetics.

　　Dieting to lose weight is difficult for many people to stick to for a long time, but once they get past that point, dieting becomes a hunger strike, and some symptoms of anorexia nervosa gradually appear, which is enough to make people turn pale. So how can we avoid anorexia caused by excessive weight loss?

　　Yangzi Evening News/Zi Niu News reporter connected relevant experts — —

　　Anorexia patients often have mental disorders in the front and abnormal behaviors in the back.

　　Wang Ting, director of the Department of Psychiatry, Nanjing Hospital of Traditional Chinese Medicine, said in an interview that such diseases belong to mental and psychological diseases with eating disorders as the main factor. Patients have unusual ideas and "cruel and excessive" behaviors about their own weight and body shape. For teenagers, they usually appear at the same time with depression and bipolar disorder. "They are not satisfied with their weight, figure or appearance, and will do whatever it takes to try to prove themselves, and feel that they are doing it themselves. Therefore, there will be situations in which Xiaoling is unwilling to go to the hospital for treatment, resistance and self-harm. Modern research has suggested that changes in social culture, including aesthetics, peer induction and demonstration, and patients’ brain structure and function may be induced.

　　Although the loss of life due to weight loss is a real case, there are not a few people who have "appearance anxiety" nowadays, and patients who have health problems after extreme weight loss are not uncommon. Miao Weifeng, chief physician of the Department of Spleen and Stomach Diseases of Nanjing Hospital of Traditional Chinese Medicine, has received several patients with anorexia nervosa, which is regrettable. "In fact, many patients are already very thin. There is a 19-year-old girl, who is about 70 pounds tall and 6 meters tall, but she still has the idea of losing weight." Miao Weifeng recalled that there was another female patient who was going to be 60 years old. Because of anorexia, it was almost 10 years before and after seeing a doctor, and she was already in a state of severe malnutrition when she saw a doctor. "We later found that we gave her nutritional support during the treatment, but in order not to make herself fat, she even secretly dumped the nutrient solution we hung for her from the infusion pimp."

　　At present, the etiology of anorexia nervosa has no clear mechanism, which is generally related to personality and environmental factors, and the genetic factors are not clear. Shen Diwen, deputy director of the Department of Medical Psychology, Nanjing Gulou Hospital, also said: "Patients with anorexia nervosa tend to pursue perfection, especially for their body shape and appearance. In addition to dieting, they may spit out what they have eaten by withholding and other methods. But in fact, when these behavioral abnormalities are found, it is often necessary to take compulsory measures to intervene and stop, and seek professional treatment from doctors. "

　　Anorexia can lead to systemic problems, and solving emotional diseases is the key.

　　Nutrition is not enough if you don’t eat, and emaciation is the most common manifestation. However, at this time, "emaciation" may not be regarded as beauty, but a pathological symptom. "There is a problem with emotions, which will have an impact on whether it can be digested or absorbed." Miao Weifeng told reporters that from the perspective of Chinese medicine theory, although the related symptoms of anorexia nervosa are mainly located in the spleen and stomach, it is actually closely related to the liver, heart and kidney, and it is a systemic disease.

　　Miao Weifeng further explained that serious weight loss may cause many problems to the body, leading to abnormal hormone levels including sex hormones in the body. "Women are most likely to have menstrual disorders and even amenorrhea, which may affect fertility after a long time. For men, long-term malnutrition and nutritional disorders will also lead to systemic weakness. "

　　At the same time, experts pointed out that there will be a lack of certain elements in severely malnourished people, which will also lead to other secondary diseases. "For example, vitamin B deficiency, aphtha and peripheral nerve inflammation may occur." Shen Diwen introduced that at present, the main treatment for anorexia nervosa is psychotherapy combined with antidepressant treatment. Psychotherapy refers to changing cognition to promote better positive behavior, while the latter mainly improves appetite demand by adjusting emotions and compulsion. In addition, nutritional therapy should be added when necessary to prevent malnutrition.

　　Deformed "thinness is beauty" is not desirable. Losing weight by "fasting" without science will slowly devour you who are addicted.

　　I hope Xiaoling’s tragedy will be seen by all those who want to lose weight. Don’t repeat the same mistakes and don’t make family and friends sad.
