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."

Dong Mingzhu talks about Gree’s change of ownership: it is not full of dissatisfaction, and steady development does not depend on a certain shareholder.

On December 28th, the 4th "Make the World Love Made in China" Summit Forum was moved to the headquarters in Gree Electric, Zhuhai, which was the first large-scale event held at the headquarters after the transfer plan of Gree Electric (000651) was finalized.

When interviewed by reporters after the meeting, Dong Mingzhu, the chairman of Gree Electric, said that he was "not satisfied or dissatisfied with the scheme" when talking about the transfer of control rights. She said that the steady development of Gree Electric over the years is not due to a certain shareholder, but mainly depends on the management team. This time, Zhuhai SASAC withdrew from the position of major shareholder in the hope that Gree Electric would become a more market-oriented listed company.

Dong Mingzhu also stressed that after the transfer of Gree Electric’s controlling stake, there will be "three invariants": the integrity of society, the cultivation of employees and the protection of the legitimate interests of shareholders cannot be changed.

Dong Mingzhu, Chairman of Gree Electric 

Withdrawal of state-owned assets: in order to establish a more market-oriented system.

On December 15th, Zhuhai SASAC officially approved Gree Group’s plan to transfer 15% of Gree Electric shares to Zhuhai Mingjun. Gree Electric will become a public company without controlling shareholders and actual controllers.

Dong Mingzhu explained that Zhuhai SASAC sold its shares in the hope that Gree Electric would become a truly public company. Dong Mingzhu quoted Guo Yonghang, secretary of Zhuhai Municipal Party Committee, as saying that the government should "show up immediately when enterprises need it;" When enterprises don’t need it, you are far away and keep a clear political and business relationship. " Dong Mingzhu said that the focus of this transfer of Gree’s control right is not the withdrawal of state-owned assets, but the establishment of a market-oriented system for listed companies to operate and develop better.

In addition, the transfer of control rights in Gree Electric was also promoted under the background of the accelerated development of Guangdong-Hong Kong-Macao Greater Bay Area. "Zhuhai is located in the center of Greater Bay Area. We have more thoughts and positioning for the future construction of Greater Bay Area and the development of Zhuhai. I feel that through this equity transfer, more listed companies will be built for Zhuhai, and (Zhuhai) will become a more market-oriented place that is conducive to the faster development of enterprises. " Dong Mingzhu said that the equity transfer is of far-reaching significance.

According to the announcement on December 2nd, the price for Gree Group to transfer 15% equity of Gree Electric is 41.66 billion yuan. If the transaction is finally made at this price, the takeover party will have a floating profit of 16.6 billion yuan by taking this 15% equity based on the current share price of Gree Electric.

Dong Mingzhu revealed that Gree Electric will build Gree Tower in Hengqin, Zhuhai, to provide some support for the development of Macao. "Although there are more than 10 research institutes and nearly 100 research institutes in Gree Electric, with the diversified development, Gree will build more research institutions. Building Gree Building in Hengqin is a platform to boost Macao’s development and provide talents for the University of Macau and Macau University of Science and Technology. "

Gree Electric launches Gree three-generation mobile phones.  

Management is the biggest beneficiary? The team is pure.

Gree Electric’s 15% equity was taken over by Zhuhai Mingjun, and behind Zhuhai Mingjun, besides Gaoying Capital, Gree Electric management also participated in the shareholding. Some outsiders believe that the biggest beneficiary of the transfer of control rights in Gree Electric is the management of Gree Electric.

Dong Mingzhu responded that Gree Electric’s management is a pure team. In the past 20 years, it has never been more concerned about the company’s shares. It is bent on making Gree bigger and stronger, and there is no other idea. The development of an enterprise is not supported by capital, but by the innovative culture of the enterprise.

According to CICC’s report, Gree Group’s plan to transfer 15% of Gree Electric’s equity has properly arranged the interests of Gree Electric’s management. Among them, Gree Electric management entity will subscribe Zhuhai Mingjun 2.426 billion yuan, and get 11.10% of the capital contribution; In addition, the management entity obtains 41% of LP investment share (i.e. 20.3% of investment share) from Zhuhai Xianying (GP general partner of Zhuhai Mingjun), and can fully enjoy the management fee and GP income brought by Zhuhai Mingjun. The management entity will distribute 8% of the total GP income to the management and employees who have made important contributions to the listed company. The management entity obtained 41% controlling equity of Zhuhai Yuxiu (GP general partner of Zhuhai Xianying) for RMB 4.305 million, which can indirectly control Zhuhai Mingjun. After the equity transfer is completed, the company will promote the equity incentive plan, with the total amount not exceeding 4% of Gree Electric’s shares.

Are you satisfied with Gaoling Capital? Not satisfied or dissatisfied.

After Gree Electric threw out the intention of equity transfer, Hopu Investment was also very interested in this part of the equity besides Gaoyou Capital, but in the end Gaoyou Capital won.

When asked if he was satisfied with the equity transfer plan, Dong Mingzhu responded that this should be asked to Zhuhai SASAC.

There have been rumors before that the negotiations between Gaochun Capital and Gree management were not smooth. Dong Mingzhu responded: "Any negotiation is not smooth. If it is smooth, it will not be called negotiation." When asked if she was satisfied with the plan, Dong Mingzhu responded: "It is not satisfied or dissatisfied."

When asked how Gree Electric will cooperate or cooperate with its new shareholder, Gaoyan Capital, Dong Mingzhu replied that "at least I haven’t seen it now", and she further said, "If one capital can solve the problems of enterprises, how can we see that so many capitals are exploding today? Therefore, it is not a capital to support the development of enterprises, but the innovation of enterprises to support development. "

Gree Electric business segment readjusted.

Throw out the new strategy of "Internet of Everything" Gree mobile phone released for three generations.

On the same day, Gree Electric released the "Internet of Everything" strategy, and for the first time demonstrated a complete set of intelligent connected home appliances controlled by intelligent voice.

Gree staff demonstrated how to control refrigerators, washing machines, rice cookers, range hoods and other household appliances by voice with Gree IOT air conditioners and Gree IOT mobile phones as entrances.

Dong Mingzhu also personally released Gree Electric’s third-generation smart phone at the scene. On-site PPT shows that Gree’s third-generation mobile phone adopts a 5.99-inch full HD full screen, emphasizes the night shooting algorithm in taking photos, has intelligent IOT buttons, and controls household appliances by voice.

Dong Mingzhu said that every Gree third-generation mobile phone can directly open the "micro store in Dong Mingzhu". "With Gree’s mobile phone, you should buy Gree’s products, otherwise I will remember you."

There are also many controversies about Gree making mobile phones, but from Gree Electric, mobile phones are just an entrance to Gree’s smart home strategy.

Gree Electric has also publicly released four international leading technologies that have been identified-key technologies and applications of rare earth-free reluctance main drive motor system for new energy buses, high-efficiency reluctance variable frequency scroll compressor technology, high-performance linear servo motor and driver, and high-efficiency pneumatic suspension centrifugal compressor.

The latest information displayed in Gree Electric Exhibition Hall shows that Gree Electric’s business has been re-divided into two parts, one is consumption and the other is industry. Previously, Gree Electric’s four business segments included air conditioning, household appliances, communications and intelligent equipment. This also means that the first three sectors are now merged into the consumer sector, highlighting the overall smart home; Intelligent equipment has expanded into the industrial field.

Dong Mingzhu also confirmed the adjustment of the company’s business sector in the interview. She said that the consumer sector is the business that Gree started, and the industrial sector is the heavy weapon of the country. There is no conflict between the two. "Without high-end equipment, you can’t make perfect consumer products, and you won’t be biased."

"The most beautiful reading sound" sounded in front of the Red Building of Peking University.

  (Reporter Zhang Enjie) "With the youth of me, we will create a youth family, a youth country and a youth nation & HELIP; …” "Youth is like the early spring, like the morning sun, like the budding of a hundred flowers, like the new development of a sharp sword in Xi … …” On August 29th, recitation artists Kang Zhuang and Guo Kaimin stood together in front of the Red Mansion of Peking University, and after a hundred years’ time and space, they read the classic quotations of Li Dazhao’s Youth and Chen Duxiu’s Youth with deep affection, bringing the readers back to that passionate awakening era, and officially launched the "Meeting the Party’s Twenty Themes Reading Activities".

  Sponsored by the Propaganda Department of the Beijing Municipal Committee of the Communist Party of China, the reading activity is based on the theme of "Striving for a New Journey and Building a New Era", and is divided into three sections: the reading demonstration activity with the theme of "the most beautiful reading sound", the book exhibition and promotion activity with key themes, and the special promotion activity of the digital reading column of "Reading Beijing, Reading China and Looking to the Future".

  On the same day, General Jin Yinan told "Why China" at the Red Chamber of Peking University. He pointed out that in today’s thrilling world, only history can make us face reality without feeling scared. "By learning to read and be familiar with history, we can broaden our horizons, enhance our confidence and improve the strength of our personality. Therefore, reading is not just a pastime after a meal, it is as simple as adding some talk. "

  It is worth mentioning that the reading leading plan of "the cradle of the Party" was also released at the event site, and the initiative of reading books such as "Striving for a New Journey and Building a New Era" was put forward. In addition to this launching activity, the theme reading demonstration activity of "The Most Beautiful Reading Sound" will focus on celebrating the 20th National Congress of the Communist Party of China, and four theme reading activities will be held successively, inviting industry celebrities to read books related to the construction of "Four Centers" in Beijing.

  It is understood that major bookstores, key entity bookstores and e-commerce platforms in Beijing will set up special counters to display and sell key books in a centralized way, and all relevant units and districts will also organize and carry out a variety of reading activities on the theme of "Celebrating the 20 th National Congress" in an orderly manner, and hold lectures and knowledge contests to create a good atmosphere for the party’s 20 th National Congress victory.

La Liga: las palmas vs Atletico Madrid! Blood pressure? Why does Atletico Madrid like the home team type?

Let’s have our first chat today.La Liga: las palmas vs Atletico Madrid!

At the beginning of the season, we talked about Atletico Madrid’s away game against Vallecano. At that time, we analyzed why Atletico Madrid likes teams like Vallecano.

Coincidentally, today’s las palmas is also quite similar to Vallecano.Can Atletico continue to satisfy the fans?

This las palmas is just like.Basaer teamSame.

After playing in Barcelona for more than ten years, coach Pimienta has been a youth training echelon coach in Barcelona for twenty years.

After he came to las palmas, he brought in many players from Barcelona’s youth training to play football in Barcelona.

So,The style of this team is very similar to that of Barcelona, and many data are also very close to that of Barcelona.For example, the possession rate, the average number of passes per game, the high-pressure forced data and so on.

They have many advantages of Barcelona, such as high-intensity and effective high-level grabbing.Not only can it disrupt the opponent’s offensive organization, but it can often launch a counterattack on the spot to get a chance to break the door after stealing.

Therefore, it is very powerful for them to play the passing and controlling teams such as Huang Qian and Royal Society, and it will be very difficult for opponents to organize attacks normally.

But Atletico don’t buy it.

We introduced it before when Atletico Madrid played Vallecano.Atletico’s attack is very simple and fast, and it pays attention to the quick delivery of the ball, which will not give the opponent too much time to rush forward.

Moreover, because Atletico Madrid’s lineup is very stable, their ability to kick the ball may even be close to the level of Real Madrid.

Then, if Real Sociedad, Vallecano and other high-ranking teams that are equally fierce are hard to win the ball from Atletico Madrid, it may be difficult for las palmas.

Besides,Las palmas also has many shortcomings of Barcelona, for example, because a large number of people pressed into the frontcourt and forced to grab, which led to being easily beaten by opponents.

In almost every game this season, their opponents can get excellent scoring opportunities by playing behind them. For example, the last goal of almeria was a long pass behind them.

As far as Barcelona can play like this, it is backed by a strong defender. araujo, Comte and Christensen are all first-class in La Liga.

But las palmas doesn’t have a first-class defender. Even when playing Huang Qian, Huang Qian’s 1.95-meter high center Soloff is actually faster than their defender …

The combination of Atletico’s Gleizman and Morata is one of the best combinations in the five major leagues, and Morata is in the best season of his career, so it is hard for las palmas’s defenders to guard against it.

In addition, on the 1st, las palmas went to Manakol Island in the Mediterranean to play in the Cup, with a journey of 4,000 kilometers, which was still a bit of a toss-up.

Although the rotation has been made, many main players have also played, which may be somewhat worn out and may be at a disadvantage in physical fitness.

In the case that there is a big gap between the lineup configuration and competition experience of the two teams, if the weak side has no advantage in technical and tactical style and physical fitness, it will be difficult to play this game.

If Atletico Madrid wins tonight,You can temporarily climb to the top of La Liga.The fighting spirit may be relatively strong.

All things considered, can Atletico satisfy the fans? What do you think? The cocktail party expects them to score three points away from home!

Well, in other competitions today, Xiaojiu will still send you text analysis in the evening. If you have anything unclear, you can ask me, "Look at the ball and see clearly", and we will be there or not!

If you like it, move your fingers and pay attention to it!

Adding elevators to existing residential buildings in Hangzhou has benefited more than 14,000 households. AR real-life software for adding elevators is gradually being applied.

To improve the livable level and living conditions, the installation of elevators in existing houses in Hangzhou has entered the fourth year as a livelihood project that conforms to the people’s yearning for a better life. Up to now, 347 new elevators have been installed in existing houses throughout the year, with a total of 1156 completed.
The amount of completion doubled compared with the same period last year.
This year, 347 elevators have been installed.
"Started, not far from the day of sitting on the elevator! I finally have hope! " Residents in the colorful community of Xixing Street in Binjiang District are all excited to see one machine entering the site for construction. Although they were temporarily shut down due to the epidemic, the two-level housing, insurance and housing management departments in the urban area did not stop serving the residents, and began to make full preparations for the resumption of work early, striving to minimize the delay caused by the epidemic to the installation of elevators.
(Colorful Community Construction Site)
Since the comprehensive resumption of work, the installation of elevators in the city has sounded the horn of "acceleration". Thirteen districts, counties (cities) and Qiantang New District have gone hand in hand, strengthened guidance and coordination for local towns and communities, and made every effort to promote the process of adding stairs, such as holding a street ladder promotion meeting in Shangcheng District and Binjiang District; Gongshu district actively coordinates the pipeline department and pre-arranges the relocation and renovation of pipelines; Lin ‘an District took the lead in launching the joint trial of adding stairs … As always, it actively promoted the implementation of this livelihood project and achieved practical results. Among them, 10 districts, counties (cities) have included the work of adding stairs in the key promotion of people’s livelihood at the district level this year, so that more households can enjoy the convenience brought by installing elevators.
Up to now, the city has added 327 joint audit projects and completed 347; Over the years, 1,424 projects were started and 1,156 projects were completed, benefiting more than 14,000 households and nearly 35,000 residents.
At the same time, the Bureau is making every effort to promote the formulation of the first domestic government regulation on installing elevators-"Administrative Measures for Installing Elevators in Existing Houses in Hangzhou", striving for breakthroughs in key issues such as public opinion unification, joint review and follow-up management, which has been submitted to the Municipal Bureau of Justice for review.
"Project" and "policy" are pushing forward, and Hangzhou is making efforts to speed up the installation of elevators from "bonsai" to "scenery"
Adding ladder loan and endowment insurance
Hangzhou ladder service is innovative.
Recently, the owners who live in Xinghai Yunting, Chongxian Street, Yuhang District are very happy, because the "ladder loan" they applied for has been successfully handled, which is another step away from the realization of the "ladder dream".
This is another innovative service to promote the addition of elevators in Hangzhou. "Financing difficulty" has always been a difficult problem in the process of installing elevators in existing houses. In view of the economic ability of the disadvantaged groups in old residential areas, Yuhang District and China Bank took the lead in launching a low-interest "ladder-adding loan"-the owner can apply for a maximum credit of 150,000 yuan with ID card, household registration book, real estate license, elevator installation contract or agreement, income situation and personal credit situation, which not only meets the residents’ demand for ladder-adding, but also relieves the residents’ pressure of one-time payment. At present, many owners in Xinghai Yunting, Chongxian Street, Yuhang District and Shuixie Huadu Community, Tangqi Town have successfully applied for the "elevator loan", which also provides a blueprint for the subsequent installation of elevators in the city.
Not only that, the owners of Xinghai Yunting can also customize the most satisfactory elevator style for themselves through the first AR real-life application software in China. This "visible and tangible" ladder-adding AR real-life APPlication software was successfully piloted in Yuhang District a few days ago. The app has a variety of ladder-adding schemes and decoration configurations built in. The owner can generate the real-life effect of ladder-adding superimposed on the real residence in real time through positioning, and select the details such as the number of elevator stops, materials and colors according to the needs. Finally, it is adjusted in real time by AR real-life software in one step, which is more intuitive, simple and efficient than the previous plane drawing scheme mode.
(map of ladder service in Nanyuan Street, Yuhang District)
What’s more, Nanyuan Street in Yuhang District has also released the first map of elevator service. Through on-the-spot survey of each house in each community within its jurisdiction, the houses that meet, basically meet and do not have the conditions for adding stairs are marked with "green, blue and red". Residents can know whether their buildings meet the conditions for adding stairs by looking at the map, and they also emphasize the policies and procedures for adding stairs, which provides a detailed strategy for residents and promotes the work of adding stairs into the "fast lane".
The installation of elevators is being rolled out in an all-round way, and more and more residents enjoy the convenience of going up and down the stairs. After it is put into use, elevator maintenance and other issues have always been concerned. Focusing on the problem of "long-term follow-up management", we insist on exploring and cultivating diversified daily maintenance methods, and encourage all districts to try first according to the principle of "the owner is the main body and the market operates", and explore various ways such as owner self-management, property custody, third-party custody and elevator insurance.
This year, Daguan Street in Gongshu District tried first and made bold innovations. With micro-governance of the community as the platform and "democracy promoting people’s livelihood" as the goal, through the forms of "building a platform+participating in insurance", "convention management+participating in insurance" and "owner autonomy+participating in insurance", the streets, communities and residents made concerted efforts to promote the installation of elevator projects to actively participate in insurance. It also took the lead in realizing the first comprehensive insurance model of "15+2" elevator "for the aged" in the 1-unit elevator project of Building 8 in Xisiyuan, which provided a new model and a new path for the follow-up maintenance of elevator projects in the whole city, the whole province and even the whole country.
(At the signing ceremony of comprehensive insurance for the "15+2" elevator in Gongshu District) In this year’s 2019 reform and innovation best practice case selection activity in Zhejiang Province, Hangzhou’s unique ladder-adding model of "owner-oriented, community-led, government-guided, and support from all parties" won the "excellent practice case". This also encourages the urban two-level housing, insurance and housing management departments to step up the ladder, and will continue to vigorously promote and improve the top-level design, create quality projects, improve the long-term mechanism, and constantly realize the people’s yearning for a better life.
Reporting/feedback

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%.

Mango TV Transformation, "Under the Sun" catch me if you can, both the editor and the director are excellent!

According to the past habits, most of the dramas broadcast by Mango TV can’t escape the youth idols and sweet pets, but the opening year of 2021 is really a big surprise. The New Year’s drama chosen by Mango TV is actually Under the Sunshine produced by Bona, a big play in catch me if you can, knowing that the villain is there, but for various reasons, he can’t be brought to justice immediately. You must also make a pretence with him and deal with dozens of criminal investigation dramas!

From the first two episodes, "Under the Sun" shows a sense of suspense and tension that is not lost to this year’s hot and foggy theater. After being hijacked by gangsters halfway, the female university teacher escaped calmly and tactfully, and found that the murderer at that time changed her identity and reappeared in her life seven months later. The old policeman, who has been suspicious of the case and carefully pursued it, was victimized by the gangster’s design step by step, but he secretly left a chess piece and ambushed the murderer. The killers with high IQ and high face value play with their prey in their hands like cats, as if they don’t mind that their minions also have deadly abilities!

Not only is the story tightly woven and full of unexpected suspense, but it is also excellent in actor performance. First of all, I have to talk about Mr. Wang Jinsong. Although he has been off the production line in the third episode, he has set a benchmark for all the actors in these two episodes. Moreover, Chen Jinyan, the old policeman he played this time, is completely different from the role he interpreted before. Besides the justice of the police, he also has a special human touch, especially for Xiaowu, played by Liu Kai, who used his own dead church as a street punk to mix responsibility and justice, which also made the story have a longer-term development.

Another surprise is Peng Guanying. I have always paid close attention to this actor, not only because of his outstanding appearance and good acting skills, but also because he can often give people a reasonable role and some unexpected feelings. For example, in The Longest Day In Chang’an, the hypocritical son, a few scenes can be impressive. This time, he played the roles of Feng Xiaosheng and Shen Shijie respectively. When he first appeared, several side shots were full of ferocity. After that, the chic and arrogance of staying at the group headquarters was still a true performance. When I arrived, I played with Ke Yingshi’s abnormal eyes, which can be regarded as the most creepy scenes at the end of 2020. However, in the face of martial arts, people have to believe that people are complex and fickle animals. Such polarized emotions and performances make Peng Guanying play incisively and vividly in a short series. I believe that after the broadcast of Under the Sun, he will soon become one of the most frightening characters on the screen after An Jiahe!

On the other hand, "Under the Sun" has not forgotten the theme of guiding people to be good in film and television works while making great suspense and puzzles of human nature. From the beginning to the end, there were old policeman Chen Jinyan, victim Ke Ying and bystander Xiaowu who spared no effort to work for justice and vowed to wipe out criminal gangs and murderers. Even in the face of life and death threats and various threats from family members and relatives, they never gave up their persistence, but became more determined and more skillful in fighting criminals and crimes.

2021 is coming soon. At this time, watch "Under the Sun" on Mango TV, feel catch me if you can, who is frightening and inspiring, and understand what "justice may be late, but it will never be late!"

Why are only dragons fictional in the zodiac? How did the ancients come up with 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."

picture
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.

picture
Two-wing Ying Long portrait brick, Han. Because Ying Long can make clouds make rain, when the drought is severe, people make Ying Long look like mud, sand and stones and pray.
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.
