Zhang Yimou’s new work "Cross-border" fashion circle fashion "Butterfly" will be on stage.

1905 movie network news The second season of dialogue fable 2047, a brand-new concept performance produced by Buick and directed by Zhang Yimou, is about to premiere, and the team is rehearsing nervously recently.

In this performance, the masters of traditional folk art will join hands with the world’s top scientific and technological experts, and Zhang Yimou, who advocates cultural inheritance through innovation, even "crossed the border" fashion circle and invited the international avant-garde fashion design team of Turkish Ezra Tuba to join the performance. 

The internationally renowned Ezra Tuba team used nanotechnology and wearable technology to create the world’s first flying Butterfly Dress together with Intel. This dress can sense external stimuli, including touch, body temperature and movements. When an object approaches or movesWhen the mobile device communicates wirelessly, the butterfly on the clothes will "wake up" slowly, and gradually speed up the rhythm frequency of the wings and dance in the air as the object approaches. This time, this technology will also be applied to the unit program "Song Shu Butterfly" in the second season of Dialogue Fable 2047. When the enthusiastic Zhuang people sing Poya Song Shu, ancient songs can call "Butterfly" and bring the audience a sense of returning to nature. 

In an exclusive interview, Zhang Yimou admitted that the "cross-border" fashion circle aims to "add technology and intangible cultural heritage together with the traditional culture of China, and we hope to present a particularly good visual effect on the stage at 1+1." As early as the press conference of Dialogue Fable 2047 in the second season, Bao Ye, director of Buick Marketing Department of SAIC-GM, the producer, already said, "I am looking forward to seeing our team really make a bigger and newer breakthrough in the second season and show it to the audience." 

Get "model design" new skills: can AI control its own evolution?

  "It only takes a few lines of code to build a regression model." Programmers recognize the performance of Google AutoML and think that the model designed by AutoML is comparable to that designed by machine learning experts. A few days ago, Google engineers introduced the Google AutoML project in China and Silicon Valley respectively.

  Confused doubts followed — — AI evolved again? ! Already self-developed? Can control their own evolution? Is it to get rid of humans?

  How many steps does evolution take?

  AI has indeed evolved, and it can do more and more things and achieve remarkable results. Behind it is the "triple jump" of AI implementation path — —

  Zhao Zhigang, a researcher at the Big Data R&D Department of Jinan Center of National Supercomputing, said: "At first, we used mathematical formulas and ‘ if… … then’ Wait for the statement to tell the computer what to do in the first step and what to do in the second step, teach it by hand, and then give the machine N groups of inputs and outputs. The rules or laws in the middle are learned by itself. "

  "Before, many smart minds spent their whole lives studying how to extract effective features." Mo Yu, CTO of Smart Point, which focuses on intelligent shopping guide dialogue robots, explained, "The invention of neural network algorithm and the emergence of deep learning technology have made AI evolve to 2.0, and the work of extracting features is carried out by AI itself, and our work has also changed accordingly."

  It is easy to explain the transition from "1.0" to "2.0" with the model of mathematical function: if the tasks of image recognition, semantic understanding and chess playing are all regarded as different Y=f(X), that is, the input picture, voice or chess move of "cat" is "x", and the output cat, answer and chess move is "y". Before deep learning, people find the formula corresponding to function F through their own analysis and tell it to AI. After deep learning, people input a lot of correspondence between x and y, and AI finds the formula corresponding to function f by itself.

  "The specific content of the function F found by AI may be better than that found by humans, but humans don’t know it, just like a black box." Mo Yu said, "But the form of F is designed by AI researchers through research. If deep neural network is used, the modules in the network and the organization between modules are also designed in advance."

  With the maturity and popularization of deep learning technology, there has been a specific pursuable experience in model construction. "The release of various common neural networks has made the threshold for employment lower and lower. Some ordinary model construction and optimization, just graduated students can get started in online learning tutorials. " Zhao Zhigang said.

  When modeling becomes a learnable skill, AutoML appears. What it can do is the model design work of AI researchers. "It will help different companies build artificial intelligence systems, even if they don’t have extensive expertise." Google engineers recommend this. AI successfully evolved to 3.0.

  In fact, AutoML still replaces the work that human beings can extract experience. "If people described a set of ‘ Road network ’ With the technical assistance of deep learning, the machine can find the optimal path as quickly as possible; Then AI can now design its own road network. " Zhao Zhigang was concise.

  It can be seen that both deep learning and AutoML only replace the work that some groups of human beings have studied thoroughly. "What machines can do, try not to work by hand" is the life creed of many programmers, which gave birth to AutoML. Based on the same creed, Microsoft developed DeepCoder. "It can be used to generate programs that satisfy given input and output." Mo Yu said, but its performance is not satisfactory at present, and only some simple programs can be written.

  Who is "God"

  There is no doubt that the answer is human.

  Since AI has evolved to a higher level of model design, what changes have taken place in the "hand of God"?

  "An alchemist", Mo Yu vividly talked about his work in two words. "Smart is a professional intelligent customer service. The work of R&D personnel mainly focuses on problem modeling (how to turn actual problems into problems solved by artificial intelligence technology) and algorithm optimization (how to improve the effect of artificial intelligence algorithms)."

  "refining" means constant debugging and improvement. "For a specific person, the more you throw your temper, the better. The more accurate the answer, the better." Mo Yu said, "Our X is the customer’s question, Y is the reply of the robot customer service, and the middle function F needs training."

  This is not an easy task. If we divide the experience of human society into three categories: definite rules with formulas, knowledge that can be expressed in words, and feelings that can only be understood but cannot be expressed. The last category is the most difficult to ponder.

  "Therefore, we try to build a perfect closed-loop feedback, understand the preferences of specific users, and finally achieve what they like through the expression of emotions and interests." Mo Yu said, "At present, it is in the stage of man-machine collaboration, but the acquisition of more and more samples will help our intelligent customer service to give accurate and pleasing answers."

  It can be seen that not all fields are suitable for AI’s self-development. For example, in the aspect of problem modeling, how to abstract practical problems into machine learning problems can not be completed by AI. In the stage of AI2.0, R&D personnel also need to design the form of function F manually.

  So, what will be the future of AutoML popularization?

  "Humans are liberated from lower-level jobs." Zhao Zhigang said, "If the model design can be done by AI, then AI researchers will explore more the design of the basic modules that make up the model."

  "Developing AI models with AutoML is similar to children playing with ‘ Lego ’ Toys. " Zhao Zhigang put it in simple terms, and the designers of Lego disassembled the whole world into detailed modules, so that everything could be used and then combined into complex models. The higher level of human work is to find basic units, that is, modules, for AI in different fields. For example, in the field of image recognition, humans have designed various modules such as convolution and pooling. "AutoML can build a model based on this, and constantly adjust the module combination to obtain a more reasonable output. The finer the module, the more versatile it can be, and the more self-developed AI can be used. " Zhao Zhigang said.

   Where are the talents needed by the industry?

  Alleviating the shortage of talents is the main selling point of AutoML. "AI systems are blooming everywhere, but AI talents are far behind." Google explains why AutoML is indispensable. What is the current status of AI talents?

  In 2017, the Global AI Talent Report and the BAT Artificial Intelligence Talent Development Report were released one after another. "The shortage of AI talents is real." Xu Wenjuan, vice president of Shengshi Investment Group, said, "The shortage of talents in start-up and development enterprises is particularly serious. From the current global perspective, the United States has the largest number of AI talents, and China’s AI talents can’t be compared with it in terms of number of people and experience. "

  Zhao Zhigang has the same feeling: "China’s AI field is short of veterans, experts, generalists and top masters." The optimization and debugging of the model requires experience, the exquisite design of the model requires superb skills, and the application of AI in various industries requires compound talents. In addition, there are only a handful of top talents leading the development direction of AI, and most of them are abroad.

  Xu Wenjuan introduced that China has the most AI talents in BAT (Baidu, Ali, Tencent). Generally, there are several kinds of background experiences of such talents, such as returnees, BAT work experience, or from universities or research institutes.

  "AI self-development should not be able to replace people’s work in the short term, and there is still a long way to go." Xu Wenjuan said. Zhao Zhigang analyzed from an academic point of view: "Only when human beings design AI models in different application fields and further decompose them into a series of general modules, such as the periodic table of elements in chemistry, DNA and RNA in biology, can this self-development have more applications."

The latest report in the United States shows that the quality of Boeing 737Max aircraft is serious, and 33 of 89 audits failed.

(Observer Network News) According to the disclosure on March 11th, local time in The New York Times, USA, the FAA found that Boeing "has many problems in quality control" after six weeks of audit. Among all 89 audits, Boeing passed 56, 33 failed, accounting for more than 37%, and 97 possible irregularities were found.

The quality problem is serious, and the qualified rate of fuselage audit is less than 50%

According to the inspection report of Federal Aviation Administration (FAA) cited by The New York Times, there are dozens of problems in the manufacturing process of Boeing 737Max aircraft manufacturers and their main suppliers.

After the Mense crash of Alaska Airlines Boeing 737MAX in January, the FAA began to investigate this type of aircraft. The survey results show that 56 of 89 audit subjects passed the audit, 33 failed the audit, and the failure rate exceeded 37%. During the audit, there were 97 suspected violations.

In the investigation of 737Max fuselage contractor Spirit AeroSystems, the report showed that seven audits were unqualified, which was unreasonable by more than 50%. It is mentioned in the report that the personnel of the air safety agency have witnessed the mechanic of Spirit company using the hotel room card to check the plane’s Mense. In addition, the FAA personnel also saw the mechanic of Spirit company smearing soap liquid on the door plug as a "lubricant" during fitting, and then cleaning Mense with a wet cheese cloth.

In an audit of Mense components by Spirit Company, the investigators found five problems, one of which was that "no evidence was provided to prove that the minor design changes of the aircraft had been approved by the FAA". Another audit that Spirit failed involved the installation of Boeing 737Max in Mense. In this audit, investigators expressed their concern about the Spirit technicians who performed this work because the company "failed to clearly understand the knowledge needed to implement this process".

Other audits that Spirit failed include those involving cargo doors and the installation of cockpit windows. In this regard, Spirit spokesman Joe Buccino said that the company is "reviewing all identified non-compliance behaviors to correct them".

In the audit of Boeing, the auditors found that many problems of Boeing were not following the "approved manufacturing processes, procedures or instructions", and other problems involved the quality control of Boeing aircraft.

The FAA also rated Boeing employees’ understanding of the quality control process. In the survey, they interviewed six company engineers and graded their answers, with an overall average score of only 58%.

According to the report, the FAA has deployed as many as 20 investigators in Boeing and about 6 investigators in Spirit.

It is worth noting that Spirit AeroSystems was spun off from Boeing Commercial Aircraft Company in 2005. Boeing said this month that it is in talks to acquire Spirit.

In March, there were four vicious accidents, and Boeing whistleblowers committed suicide.

Recently, Boeing’s security issues have once again attracted attention from all walks of life.

Following the fall of Boeing 737Max 9 Mense in January, several people on board were injured, the engine of Boeing 747-8 cargo plane caught fire over Miami, and the tire of Boeing 757 fell off. Since March, Boeing has had four consecutive vicious accidents. At the beginning of the month, there were three accidents including engine fire, tire falling off and skidding off the runway.

On the 11th local time, a Boeing 787-9 caused a "strong vibration" due to "technical problems" during the flight. At least 50 people were injured in the vibration, and then the plane landed at Auckland airport.

The New Zealand Traffic Accident Investigation Committee said on Tuesday that it was detaining the cockpit voice recorder and flight data recorder (black box) of the Boeing 787-9 plane that injured 50 people on the 11th. The black box will provide more information about the flight trajectory and communication between pilots.

On March 9, local time, the government of South Carolina confirmed that John Barnett, a 62-year-old former employee of Boeing, who publicly questioned the problems in Boeing’s production line, was found dead in the car.

In 2010, he began to work as a quality manager at the Boeing factory in North Charleston, and retired in 2017. In 2019, barnett reported that the overworked employees of his Boeing factory in South Carolina deliberately installed substandard parts on the aircraft on the production line. A few days before his death, the old employee who had worked for Boeing for 32 years was still busy with his lawsuit against Boeing. He was found dead because he failed to provide testimony on the 9th.

Lawyer barnett used "alleged" to describe his client’s statement of "shooting himself".

The installed capacity of industrial robots in China has declined for the first time in ten years. Is it a signal of cold winter or a prelude to spring?

  The International Federation of Robotics (IFR) released its latest report "Global Robots 2019" in Shanghai on September 18th. This comprehensive report on the performance of the global robot market in 2018 shows that despite the two main application areas of the robot industry last year — — The automobile and electronics industries are facing headwinds, but the annual global sales of robots have reached a new high of $16.5 billion, and the global installed capacity has increased by 6% from the previous year to 422,000 units. IFR predicts that the installed capacity in 2019 will be lower than that in 2018, but the average annual growth rate from 2020 to 2022 can be maintained at 12%.

  "In 2018, we saw the ups and downs of the market performance of the robot industry, but we still created a new sales record, even though this year was the main customer of robots — — A difficult year for the automotive and electronics industries. " The International Federation of Robotics President Junji Tsuda said, "Sino-US trade friction brings uncertainty to the global economy — — Customers tend to delay investment. But what is exciting is that the annual installed capacity still exceeds 400,000 for the first time. The long-term outlook of IFR shows that the continuous automation trend and continuous technological improvement will bring double-digit growth, and it is estimated that the installed capacity will reach about 584,000 units in 2022. "

  According to the report, the top five industrial robot markets in 2018 are China, Japan, South Korea, the United States and Germany, accounting for 74% of the global installed capacity.

  After eight years of rapid growth, the installed capacity of industrial robots in China showed an inflection point last year, with a slight decline. However, China is still the largest industrial robot market in the world, accounting for 36% of the installed capacity in the global market.

  In 2018, the installed capacity of industrial robots in China was about 154,000 units, which was 1% lower than that in 2017, but still more than that in Europe and America combined. Last year, the total installed capacity of robots in China market reached 5.4 billion US dollars, an increase of 21% compared with 2017.

  The annual installed capacity of industrial robots in China market from 2008 to 2018. The pictures in this article are all from the report of Global Robots 2019.

  In 2018, the density of robots in manufacturing factories in China (the number of robots per 10,000 workers) was 9.3 times that of 2010, reaching 140. In the picture, the blue column shows the density of robots in China, and the red curve shows the global average level.

  Nevertheless, there is still much room for improvement in the scale application of robots in China’s manufacturing industry. Globally, the density of robots in Singapore, South Korea and Germany ranks the top three, reaching 831, 774 and 338 respectively.

  In 2018, the differentiation between independent and foreign brand robots was obvious. The total installed capacity of China local robots in the domestic market has increased by 5% (27% in 2018 and 22% in 2017), which shows that China’s policy orientation of encouraging its own brand robots has brought results. On the other hand, the installed capacity of foreign brands (including products produced by non-China suppliers in China) decreased by 7% to about 113,000 units (2017: about 122,000 units).

  From 2016 to 2018, the annual installed capacity of industrial robots in various industries in China market. Electrical/electrical industry, automobile industry, metal and machinery industry have always been the top three application industries, but in 2018, the installed capacity of industrial robots in these three industries all declined. On the contrary, other industries have increased.

  Annual supply of foreign robot brand suppliers and China local suppliers in various industries in 2017 and 2018. Under the background of declining automobile sales, the demand for industrial robots in automobile manufacturing industry is also decreasing. In the automobile industry, the market share of foreign brands is over 80%, which also explains why the sales of foreign brands of robots suffered a greater market impact last year.

  As for the industrial robot market, which tends to be weak since last year, the robot companies interviewed by The Paper (www.thepaper.cn) during the 21st China Industry Expo recently said that the so-called "cold winter" in the industry is only a temporary phenomenon.

  Li Gang, head of ABB’s robotics and discrete automation division in China and ABB’s robotics business in China, said that from the second half of last year to the first half of this year, sales and output in the China market, especially in the automobile market, did decline. But these declines are short-lived. In the long run, ABB is still optimistic about the development of China market. The reason is that China is changing from "manufacturing" to "intelligent manufacturing" and from a manufacturing power to a manufacturing power, and the basic elements of the market have not changed.

  The epitome of the company’s optimism about the China market is that its new robot factory and R&D base in Shanghai have recently officially broken ground. The new factory is expected to be put into operation in 2021, with a total investment of 150 million US dollars (about 1 billion yuan). After completion, it will become ABB’s largest robot production base, and together with Swedish factories and American factories, it will form ABB’s global robot supply system.

  Wang Hui, CEO of KUKA China, another "four families of global industrial robots", told The Paper that from the general trend, industrial robots still have a good development prospect in the next 10 to 20 years, although difficulties and constraints may be interspersed in the process. How does the hot artificial intelligence combine with industrial robots? How to move from concept to application? It is a trend worthy of attention in the future development of industrial robots.

  Cao Yunan, general manager of Suzhou Ailite Robot Co., Ltd., a domestic industrial robot enterprise, also believes that the decline in sales of industrial robots in China is a temporary phenomenon. "Due to industrial upgrading, it is true that the 3C industry and the automobile industry are going downhill. But apart from these two traditional tracks, there are still many growing tracks for robot companies, such as logistics and consumer-oriented applications. "

  At the press conference of Global Robotics 2019, Qu Daokui, chairman of China Robotics Industry Alliance and president of Xinsong Group, pointed out that in 2018, the sales volume of industrial robots in China declined for the first time, but the annual sales volume ranked first in the world for the sixth consecutive year, and the sales of self-owned brand robots maintained steady growth. Based on the current market situation and industry operation situation, China Robot Industry Alliance preliminarily predicts that the sales volume of industrial robots in China will increase by about 5% in 2019, among which the sales volume of self-owned brand industrial robots will increase by about 15%.

Can swimming really cure children’s asthma?

  Can swimming really cure children’s asthma?

  Expert interpretation: This disease is difficult to cure and can only effectively avoid inducing factors.

  Recently, some media reported that Sun Yue, a singer who left the stage for eight years, revealed in a recent program that she was actually treating asthma with her children after disappearing from public view for so long, and all the methods were exhausted, but the results were not satisfactory. Finally, the doctor suggested giving it a try by swimming, from swimming with her children three times a week to swimming with her every day, and finally cured her asthma. In this regard, the reporter interviewed Yao, the father of a Chinese medicine doctor, deputy director of the Department of Pulmonary Diseases of the Second Hospital of Jiangsu Province, and learned that asthma is a stubborn disease, and the possibility of complete cure is slim. Swimming, as a kind of exercise to help exercise cardiopulmonary function, can effectively control the onset of the disease, but once the vigilance is relaxed and the long-term care of prognosis is neglected, asthma may still "make a comeback".

  "Asthma, as a chronic disease, mostly occurs in young children, and there is the possibility of continuing the whole life cycle of patients. If early detection and early intervention treatment can be carried out in childhood, the disease can be well controlled and the possibility of children’s asthma evolving into adult asthma can be reduced." Yao, the main father, said that children’s immunity and other aspects are still not well developed during their growth, but with the increase of age, their resistance is enhanced, their lung function is constantly developing, and the chances of respiratory virus infection are greatly reduced, so many children with asthma will obviously reduce their symptoms after puberty, or even stop having attacks, provided that some inducing factors, such as allergens, respiratory infections, tobacco smoke, strenuous exercise or mood swings, are effectively avoided.

  Many people think that it is best for asthma patients not to exercise or reduce exercise to avoid aggravating the possibility of asthma attacks. In fact, this idea is very one-sided. According to Sun Yue’s words on the program, swimming is one of the effective ways to treat her son’s asthma. Patients can recover the development of lung function and strengthen their physique through exercise. Studies have found that the benefits of regular exercise for asthma patients far outweigh the risks.

  In addition to swimming, moderate jogging, ball games and other aerobic exercises in which all large muscle groups participate are good choices. "Patients can carry out moderate-intensity exercise under the premise that professional doctors provide scientific and regular exercise guidance, and gradually increase the duration of exercise. Patients who are in the acute attack period are not advised to exercise. They need to follow the treatment specifications and take a full rest. At least two weeks after the asthma symptoms are controlled, they should exercise according to the actual situation. " Father Yao said.

  "For asthma patients who have well controlled their illness, it does not mean that they have entered the’ safe box’. With the change of age and the decline of immune function, exposure to some allergens or respiratory infections will induce the recurrence of asthma." My father Yao reminded that asthma patients need to maintain good living habits for a long time, such as avoiding the inhalation of harmful gases such as lampblack, cigarettes and second-hand smoke, so as to avoid long-term and chronic irritation to the airway. Patients with allergic asthma with definite allergens should pay attention to isolating animal hair and pollen. In addition, obesity is also a risk factor for the recurrence of asthma, because excessive weight will limit the expansion of the chest and lead to dyspnea. Obesity is also related to the inflammatory reaction of the body, which will affect the control effect of asthma to some extent.

Xi he Imperial Day, illustration, modern, Yan Xiaonan. Xi he is both the god of the sun and the god of making calendars. Gao You said in the note "Huainanzi Astronomical Training": "Ride by car every day, drive with six dragons, and xi he will control it."

It is generally believed that the dragon is an imaginary animal that does not exist in reality. However, human imagination is not rootless water, and any imagination must have its realistic prototype. Which animal did the dragon originate from in nature?

Dragon and snake entanglements

There have always been different opinions on the above question, including crocodile theory, lizard theory, snake theory, pig theory, dinosaur theory, hippo theory and horse theory, etc. At present, there is no conclusion. Among these animals, the relationship between snakes and dragons is quite intriguing. Dragons, like snakes, have long curved bodies that can be coiled and stretched.(The difference is that dragons have enough but snakes don’t). In many ancient books, dragons and snakes often go hand in hand. "Under the Yi Cohesion" records that "the trend of dragons and snakes is to survive"; In the Eastern Han Dynasty, Wang Chong also said that "the dragon is like a snake, and the snake is like a dragon" in "On Balance and Telling Rui". Later, Bao Puzi, a book written in the Eastern Jin Dynasty, clearly pointed out: "There are dragons of nature, and there are dragons transformed from snakes." This sentence shows that at least some dragons evolved from snakes. So far, people have always called snakes "little dragons". In folklore, there is a story about the mutual change of dragons and snakes. It is said that there is a dragon in Tanzhe Temple in Beijing, which flew away on a stormy night, leaving two snake-like "dragons". In addition, there is a Bailong Temple on Mount Emei in Sichuan. Although the temple is named after the dragon, it commemorates the white snake in The Legend of the White Snake.(White Snake).
About because of this origin, the phenomenon that snakes and dragons are mixed and called is common in ancient books. People can often find the image of "human head snake body", such as Fuxi and Nu Wa. The Han Fu "Lu Lingguang Dian Fu" contains: "Fuxi scales, Nuwa snake body." Guo Pu, a native of the Eastern Jin Dynasty, wrote in The Classic of Mountains and Seas and the Wild West Classic: "Nu Wa, an ancient goddess and emperor, has a snake-faced body, which changes from seventy to seventy in a day, and her abdomen becomes this god." Fuxi and Nu Wa are also snake heads in the Silk Painting of Fuxi Nu Wa Tu unearthed from Astana Tomb in Turpan, Xinjiang. "Liezi Huangdi" yue:

"Dong offer’s?(Fuxi), Nuwa, Shennong(Yan Di)Xia Houshi, a snake with a human face, a bull’s head and a tiger’s nose: this is inhuman and has the virtue of a great sage. "
Apart from Nvwa 、 Fuxi and Emperor Yan, there are many mythical figures in China who are also human heads and snakes. For example, "phase liu, nine faces, snake body and green", "Gong Gong, snake body and Zhu Fa" and so on. The most striking thing is that "Shan Hai Jing Overseas Western Classic" records: "The country of Xuanyuan … in the north of women’s country, people face the snake, and the tail meets the head." "Xuanyuan" is the title of Yellow Emperor. In the Ming Dynasty, Tao Zongyi said that Xuanyuan was "a dragon with a head" in Shuo cymbals. The same god is sometimes called "snake body" and sometimes called "dragon body". This proves that the two refer to the same thing, that is, the "snake body" is the "dragon body".

For such a phenomenon, Wen Yiduo thought in Fuxi Kao in his early years:

"The dragon totem, whether it is like a horse, a dog, a fish, a bird or a deer, is a snake in its trunk and basic form, which shows that in the era when many totem units were in the first place, the snake totem was the most powerful among them, and the merger and melting of many totems was the result of the merger and assimilation of many weak units."

From the viewpoint of "dragon and snake are integrated", among the many fairy animals with different forms and characteristics recorded in Shan Hai Jing, which can be regarded as a master of ancient myths, there are many who have "dragon bodies (snake bodies)". For example, "Shan Hai Jing Nan Shan Jing" says: "From Tianyu Mountain to Nanyu Mountain, every 14 mountains, 6,530 miles, have a dragon body and a human face." When offering sacrifices to these mountain gods, a white dog is used as a sacrifice, and the polished rice used for the sacrifice is glutinous rice. "Shan Hai Jing Zhongshan Jing" is the cloud:

"Every shouyangshan, surrendered to the mountain as for the third mountain, jiusan, two hundred and sixty-seven. Its gods are all dragons and faces. "
The practice of offering sacrifices to these mountain gods is different. To preside over the sacrificial ceremony, a rooster should be buried in the ground as a living sacrifice. Cereal grains such as millet, millet, rice, sorghum and wheat should be used as the refined rice for sacrifice. In Shan Hai Jing Bei Shan Jing, the "dragon with a human face" becomes a "snake with a human face". The so-called "from the mountain of a single fox to the dike mountain, where there are 25 mountains and 5,490 miles, their gods are all snake with a human face". When offering sacrifices to these gods, a rooster and a pig used as sacrifices should be buried in the ground, and a jade Jue should be used in the beautiful jade for offering sacrifices to the gods, only buried in the ground without using rice for offering sacrifices. The most peculiar thing is the mountain gods in Shan Hai Jing Nan Shan Jing: "Where the South Second Classic is the first, from Guishan to Qiwu Mountain, where there are seventeen mountains, 7,200 miles, their gods are all dragons and birds." The appearance is different, and the way of sacrifice is naturally different. When offering sacrifices to these mountain gods, a jade jade must be buried in the ground with the sacrificed livestock, and the refined rice for the sacrifice should be used.

The picture of Fuxi Nuwa, in Tang Dynasty, is colored in silk, with a length of 220 cm and a width of 116.5 cm. It is now in the Museum of Xinjiang Uygur Autonomous Region and was unearthed in Astana cemetery in Xinjiang in 1965.Fuxi and Nu Wa in the painting are the images of human heads and snake bodies.
In addition to these four-sided mountain gods, there are also records of "dragon (snake) body" gods in Shanhaijing, Xishan Classic and Overseas North Classic. For example:

"There is a god, and the human head is snake-shaped, long as a shaft, with a head on the left and right, purple clothes and a crown, which is called Yanwei."

"phase liu, nine faces, snake and green. Dare not shoot north, afraid of the stage of gong gong. Taiwan is in its east. "

In The Classic of Mountains and Seas, phase liu is a courtier of the water god Gong Gong. He can eat food from nine mountains, and the land he passes through becomes a swamp, making it difficult for birds to live and causing floods. By the way, phase liu appeared in the Hollywood movie "Fantastic Night at the Museum 3" ten years ago, but his image was depicted as a nine-headed python. In fact, this is not in line with the statement of "human head and snake body" in Shan Hai Jing.

The film depicts it as a nine-headed python, which is actually not in line with the statement of "human head snake body" in Shan Hai Jing.

"Ying Long" has wings.

Shan Hai Jing, of course, does not lack the records of "complete form" dragons. The so-called "complete form" is the dragon image that people are familiar with today, that is, the "dragon has nine similarities" summarized by Luo Yuan in Er Ya Yi in Song Dynasty."Dragon, with horns like deer, head like camel, eyes like rabbits, neck like snakes, abdomen like salamanders, scales like fish, claws like eagles, palms like tigers, ears like cows."If the dragon grows wings again, it is called "ying"Dragon ". For example, Guo Pu notes: "Ying Long, the dragon has wings", and "Guangya Release Fish" also records: "Ying Long is called with wings."
There are also many records of Ying Long with wings in Shan Hai Jing. For example, The Wild North Classic records that when Chiyou led a group of monsters to attack the ground of Zhuolu under the jurisdiction of the Yellow Emperor, the Yellow Emperor first ordered Ying Long to go out to fight. Ying Long is good at storing water, and plans to drown the ranks of Chiyou in Jizhou wilderness with huge rain. Unexpectedly, the cunning Human-God was ready, so he invited Fengbo Rain Master to take the lead in setting up a big storm. Ying Long’s power was hard to exert for a while. When the Yellow Emperor saw it, he sent his heavenly daughter "Hao" to help. "Hao" has the ability to stop the wind and rain. At that time, Ying Long and Chi-you took advantage of the storm, unable to withstand it, and were defeated and killed. From the historical perspective, the battle between Huangdi and Chiyou was naturally early.The struggle between human tribes can never be assisted by gods as in the Romance of Gods. Ying Long, Chi-you, and even Fengbo Rain Master of Chi-you were probably just the names of the tribes at that time. Among them, the tribe named "Ying Long" takes some kind of winged dragon as its totem.

"Ying Long Painting Rivers", a sculpture, is located in Dayu Mythological Garden in Wuhan. The heckling words in "The Songs of the South" link Ying Long and Dayu’s water control. Dayu "tried his best to ditch the river and guide Sichuan and Yiyue", and Ying Long was ordered to open the way ahead. It draws the land with its tail, and wherever it is drawn, the river road it opens extends to where it is drawn.
In Shan Hai Jing, next, Ying Long pushed on and met Kuafu. Kuafu is a well-known mythical figure. Shan Hai Jing Da Huang Bei Jing recorded: "Kuafu overreached himself, and wanted to pursue the scenery of the sun and caught it in Yugu. I will drink the river but not enough. I will go to osawa and die here before I arrive. " This is the famous story of "Kuafu chasing the sun". However, the same book also records another statement. "Ying Long has killed Chiyou and Kuafu, so he went to the south." In the war between the Yellow Emperor and Chiyou, Kuafu sided with Chiyou and became the enemy of Ying Long. For these two different records, Guo Pu thought:

"Kuafu in Shangyun overreached himself and died in competition with Japan. Today, Fuyun was killed by Ying Long, and his death has no name. He sent it when he touched something, which shows that his changes are not square and cannot be measured."

Ying Long. There are many records of Ying Long with wings in the Classic of Mountains and Seas, and the Map of Mountains and Seas: A Catalogue of Animals in the Classic of Mountains and Seas was painted by Li Yunzhong, People’s Literature Publishing House.

Ying Long defeated Chiyou first and then killed Kuafu, which made great contributions to the victory of the Yellow Emperor, but it also paid a heavy price for it. Shan Hai Jing Wild East longitude records that "Ying Long is in the South Pole, killing Chiyou and Kuafu", and he may also be weakened in the struggle, so he "can’t get back."(unable to return to heaven)",can only live in the northeast corner of the wild, there is a mountain called fierce plow mound". And the sky lacks the god of clouds and rain, so the drought in the lower bound has been going on for years. Shan Hai Jing Da Huang Bei Jing said that after Ying Long killed Kuafu, he "went to the south, so it was rainy in the south". Guo Pu said: "It’s a long story, and it’s similar to each other." That is, where the dragon goes, the precipitation goes.

Because Ying Long can make clouds make rain, when there is a serious drought, people make Ying Long look like mud, sand and stones, and pray, "Drought is like Ying Long, but heavy rain". In this way, there is another "earth dragon" in the dragon family, and the folk also have the custom of "repairing the earth dragon after drought". There are also many records about the earth dragon causing rain. Huai Nan Zi Shuo Shan Xun said that "saints use things, if they use Zhu Si to make friends with pigs, if they seek rain for the earth dragon".

As for the image and skills of Ying Long in ancient mythology, even Qu Yuan expressed doubts and feelings in Tian Wen: "What is Ying Long’s painting? What is the calendar of rivers and seas? " For this sentence, Wang Yi notes:

"When Yu treated the flood, a dragon painted the land with its tail. Those who guide the water should be decided, so they should be treated. "

HongXingZu note cloud:

"The" Mountain and Sea Classic Map "cloud, Xia Yu governs the water, and Ying Long draws the land with the tail."

The heckling words in "The Songs of the South" link Ying Long and Dayu’s water control. Dayu "tried his best to ditch the river and guide Sichuan and Yiyue", and Ying Long was ordered to open the way ahead. It draws the land with its tail, and wherever it is drawn, the river road it has opened extends to where it is drawn. If Dayu is a model of whole-hearted water control, then Ying Long can be regarded as the number one hero of Dayu’s charge. As for the realistic prototype of "Ying Long painted the land with the tail"(or the truth)Some scholars think that it is possible that Dayu got help from the clan with dragon totem in water control, or that it is a reflection of the joint water control of the clan with dragon totem; Mr Wen Yiduo thinks:

"The dragon who paints the land into a river is Yu himself, and the dragon who can paint the land into a river is the dragon who digs the river totem. It coexists with the ancestor Yu and is contradictory, so he sent the dragon as Yu’s teacher, saying that Yu’s method of water control came from the dragon."

In a word, such myths in Dayu’s water control are unlikely to be imagined out of thin air.

There are many dragons.

It is worth mentioning that the book Shu Yi Ji, written in the Southern Dynasties, also records:

"Hydra turned into a dumpling in 500 years, a dragon in 1,000 years, a horned dragon in dragon five in 100 years and a Ying Long in 1,000 years."

It can be seen that it takes thousands of years for Ying Long to grow up, which is the highest level of dragons-that’s why it grows wings. "Guang Ya Shi Guo" cloud:

"There are scales called dragons, wings called Ying Long, horns called a dragon, horns called a dragon, and dragons without horns called a dragon. Before ascending to heaven, they called a dragon."

It shows that the types of "dragons" described in ancient books are ever-changing and varied.

Although Shuo Yi Ji regards Jiao as the predecessor of Dragon, other ancient books don’t think so. The authoritative Shuo Wen Jie Zi clearly points out:

"Dumpling, the dragon is also. There are 3,600 fish in the pond, and the dumplings are long. "

There are many records about dumplings in Shan Hai Jing. For example, "Haineixijing" cloud:

"There are tree birds in Kaiming South, with six songs; Dumplings, scorpions, snakes, scorpions, leopards, and birds rank trees in the surface pond. "

Zhongshan Jing contains:

"Ten times once the first of jingshan mountain, yue wing at the mountain. Turbulent water flows out, and the east flows into the economy; When the water comes out, it flows to Han in the southeast, and many of them are awkward. "
Although these records only refer to "Jiao" but not "Dragon", in fact "Jiao" refers to "Dragon". Because Guo Pu said, "Dumplings are like snakes, with four legs and dragons."

From the records of Shan Hai Jing, Jiao(dragon)Living in all kinds of rivers. It didn’t leave a good impression in the minds of the ancients. According to the Records of Collected Notes, according to legend, during the Tang and Yao Dynasties, there was a big dumpling, "Three rivers overflowed and the sea was in the same stream", and its prototype was obviously an aquatic animal. In the famous story of "eliminating three evils around", one of the evils refers to "dumpling under the long bridge". Guo Pu commented:

"Dumpling is like a snake, but its four feet are small, its head is thin, its neck is covered with white scabies, and the big ones are more than a dozen. Its eggs are like a stone urn, which can swallow people."

These characteristics are easily reminiscent of crocodiles in reptiles. However, there is only one kind of crocodile living in China today, that is, the Chinese alligator living in the middle and lower reaches of the Yangtze River. However, this kind of animal has a mild temperament and there are few records of attacking people since ancient times. Obviously, this can’t be related to the dumpling that can swallow people. Fortunately, it is also recorded in the history books that there was an "alligator disaster" in the Hanjiang River Basin in Lingnan in the Tang Dynasty. When Han Yu, a famous writer in Tang Dynasty, was demoted to Chaozhou, he tried to warn crocodiles and throw pigs and sheep into evil streams.(now Hanjiang, Guangdong)Tell the crocodile to leave, otherwise it will be slaughtered, and write down the famous prose "Sacrificing Crocodiles". Since Han Yu mentioned that crocodiles "eat people, livestock, bears, roes, deer and roes to fatten their bodies", it shows that this kind of crocodile is not so docile as the Chinese alligator, but it is similar to the living habits of the Gulf Crocodile that still lives in Southeast Asia today. The latter is the largest reptile in the world, with a fierce temperament. It not only eats animals in the water, but also often hurts people ashore, posing a great threat to the production and life of the ancients. According to the latest research results, this crocodile, which was "infested everywhere" in the Tang Dynasty, is an extinct branch of the alligator, known as the Chinese Hanyu crocodile.(Hanyusuchus sinensis). Perhaps it was out of awe of this fierce crocodile that the ancients mixed with the concept of snakes and mythologized it as a "dragon".

Guo Pu commented that "a dumpling is like a snake, but its four feet are small, its head is thin, its neck is covered with scabies, and the big one is more than ten, and its eggs are like a stone urn, which can swallow people". These characteristics are easily reminiscent of crocodiles in reptiles.

Bronze dragon, Han, now in the Cleveland Museum of Art, USA. Similar to Jiao, Jilong is also a hornless dragon. Shuowen said that it is "yellow if it is a dragon" or "it is said that it has no horns".

Similar to Jiao, Jilong is also a hornless dragon. Shuowen says that it is "yellow if it is a dragon" and "stinging if it has no horns". There is a story in Huainanzi that a dragon is better than a snake eel: one day, a red dragon is killed.(without horns)And a blue dragon.(angular)Roaming together, came to Jizhou ground. At this time, the weather is refreshing and the earth is stable. When a dragon and a dragon find delicious food, they eat it with relish. Because the range of activities is within 100 acres, it is despised and laughed at by a snake and an eel. They shouted, "Hey, dragon, dragon, dare you go to the river and sea with us?" A dragon and a dragon accepted the challenge, so "the wind and the freezing rain rocked up" and "moved the world and vibrated the sea", which scared the snakes and eels into the deep mud and dared not come out.

On the other hand, although dragons are miraculous, there is still a striking situation in ancient myths, that is, dragons are often used as the object of command by people with noble status. In this regard, "Shan Hai Jing" records that "Ju Mang in the East, birds and faces, take two dragons"; "Western Ru Shou, with a snake in its left ear, rides two dragons"; "Northern Yujiang, black hands and feet, riding two dragons"; "Zhu Rong in the south, a beast with a face, rides two dragons". Thus, the dragon is the mount of the four gods. Gao You also said in his note "Huai Nan Zi Tian Xun", "Ride by car every day, drive with six dragons, and xi he will conquer it."

In The Classic of Mountains and Seas, The Wild West Sutra, the ancient emperors were even seated on the dragon:

"Outside the southwest sea, south of Chishui and west of quicksand, there are two green snakes and two dragons, named Xia Hou Kai. If you go to heaven for three times, you will get the following nine arguments and nine songs. This field of great mu is 2,000 meters high, and it won the opening song "Nine strokes". "

Kai is the son of Yu and the first "hereditary" monarch in China’s ancient historical records. It goes without saying that in ancient mythology, this element of revealing identity through "Lapras", "Imperial Dragon" or "Driving Dragon" has also become a common means of deifying monarchical power in later generations.

Swimming an hour to eliminate 1000 calories? Why are you getting fatter and fatter?

  Many people say that swimming is one of the best exercises to lose weight. Swimming for one hour can eliminate 1000 calories, which is almost the sum of the calories a person needs in a day.

  Does this mean that as long as you swim for an hour, the calories you eat in a day will disappear? Can it really consume that much? Then why do some people get fatter after swimming?

  How many calories can swimming consume?

  In fact, swimming consumes 1000 calories per hour, which is not accurate and comprehensive. The amount of heat consumed per hour varies greatly with different intensities of swimming.

  According to the data of "Nutrition and Dietary Guidelines for China Residents (2016)", a 66 kg male, with an average freestyle/backstroke of 30 minutes, consumes 264 kilocalories; Breaststroke for 30 minutes consumes 330 kilocalories; Butterfly swimming consumes the most calories, which is 363 kilocalories.

  In contrast, a 56 kg woman spends an average of 30 minutes in freestyle/backstroke, consuming 224.1 kilocalories; Breaststroke for 30 minutes consumes 279.9 kilocalories; The maximum calorie consumption of butterfly stroke is 308.1 kilocalories.

  Although you don’t exercise for an hour and consume 1000 calories, it is undeniable that swimming does burn fat. In contrast, a 66 kg man jogs for 30 minutes on average and consumes 231 kilocalories. A 56 kg woman jogs for 30 minutes on average, and consumes 195.9 kilocalories. In addition, another advantage of swimming is that there is no damage to the knees.

  Why did you get fat after swimming?

  But why do some people get fatter and fatter after swimming? First of all, it has much to do with how much you eat. Dr. Wu Xi, an associate professor in the Department of Endocrinology and Metabolic Diseases, Huashan Hospital affiliated to Fudan University, pointed out that losing weight actually creates a calorie gap and consumes a lot of calories, but it is impossible to lose weight by taking more. People usually feel hungry after swimming and want to eat food with high fat content. Some people feel that they consume so many calories, and when they get home, they can eat some high-calorie foods with peace of mind, not only will they not lose weight, but they will also get fatter and fatter. Sometimes, after swimming for an hour, a bottle of coke will offset it.

  You should still eat some foods with high fiber and low calorie before and after swimming, including bananas and tomatoes. It is not good to eat when you are hungry, which is easy to cause overeating.

  Dr. Wu Xi pointed out that exercise to lose weight should be a long-term and persistent lifestyle, and weight loss should also be a gentle process. As long as you persist in sports with enough intensity for more than half an hour every day and keep your heart rate at 120-150 times per minute, you will eventually see results.

  Of course, there is another possibility. If you find that you gain weight after an exercise, it may be caused by drinking more water after exercise. If you gain weight after a period of exercise, it may be that the proportion of muscle has increased and the proportion of fat has decreased. Because of the high density of muscles, muscles with the same volume are much heavier than fat, so despite the weight recovery, the weight loss effect has actually been achieved, and the body will look more compact.

  "Of course, in addition to aerobic training, resistance exercise is also very important for improving basic metabolism and body shaping; Muscle training first, then aerobic exercise such as swimming and running can also prevent joint injury. Every week, 1-2 times, 30-45 minutes of resistance exercise, or HIIT exercise program (high-intensity interval training), which can effectively maintain and increase muscles. " Dr. Wu Wei said.

  We should pay attention to these problems when swimming safely.

  Summer is the season of rapid growth of various pathogenic microorganisms and high incidence of various ocular surface diseases, and the average infection rate is twice as high as that in winter, especially in public swimming pools. If the disinfection measures are not strict, it will easily lead to the spread of pinkeye (infectious conjunctivitis). So how to prevent it? Can I swim during my period? The reporter interviewed relevant experts.

  Dr. Hong Jiaxu, an attending ophthalmologist at the Eye, Otolaryngology Hospital affiliated to Fudan University and a postdoctoral fellow at Harvard Medical School, suggested that you should choose a regular swimming place to ensure the water quality and wear goggles before entering the water. Regular swimming pools will sterilize the water source, but once one or two patients with pink eye enter the swimming pool, they may still infect other people.

  Pink eye disease is mainly transmitted through contact, such as towels, face plates, eye drops, coins, keyboards, door handles, faucets and so on. After touching things with germs, rubbing your eyes with dirty hands is more likely to infect bacteria. Therefore, the management of swimming pools should also strengthen supervision, prevent patients with pink eye from swimming, and strengthen the sterilization of water sources. In addition, patients with pink eye should also be conscious, swimming may aggravate their condition, so they should not go swimming in public swimming pools again. In addition, everyone should also pay attention to personal hygiene, wash their hands frequently, and don’t cross-use daily necessities such as towels.

  Huang Weihong, deputy director of obstetrics and gynecology department of Shanghai Zhongshan Hospital, pointed out that some women think that they can get into the water safely by using tampons or moon cups during menstruation, but this method is not desirable. Women’s vagina is connected with the outside world, which provides the possibility for bacterial infection. Moreover, the cervix of the uterus is relatively dilated during menstruation, and the blood flowing out of the uterus during menstruation itself is a good culture medium for the reproduction of germs. After the tampon is soaked in water, germs can easily enter the body, causing reproductive system infection.

  "Of course, if you enjoy the environment very much when traveling, and women are at the end of their menstrual period, if you really want to go into the water, it is not bad to use tampons or menstrual cups, but swimming during menstruation for a long time will increase the chance of infection, which is definitely not recommended."

  Dr. Huang Weihong said, "Female swimming during menstruation is prone to reproductive system infection or menstrual disorder, and it will not be cured for a long time."

  Dr. Huang Weihong warned that if you swim in unsanitary water, dirty water can enter the vagina, and germs can take the opportunity to cause various diseases. Although the water in the swimming pool is disinfected circularly, it is impossible to be sterile, and there is no guarantee if it is not disinfected thoroughly in some places. There are many swimmers with tinea corporis, tinea pedis, trachoma, fungal vaginitis or trichomonal vaginitis, and even patients with gonorrhea and condyloma acuminatum. They bring pathogens into the pool water and easily infect healthy swimmers.
