Embrace the wave of AI development and consolidate the "cloud base" of the digital economy

With the continuous deepening of the digital economy, the demand for artificial intelligence in many industries is increasing, and the importance attached to artificial intelligence at the national level is also increasing. Various localities have made strategic arrangements around the innovation and development of the AI industry. In this context, AI has accelerated the pace of reshaping thousands of industries. As the development trend of the AI era, the new model of deep integration with the real economy is constantly emerging, setting off a new wave of industrial transformation and urban upgrading.

Since 2019, Huawei has invested in the research and development of AI big models, and is committed to giving more value to various industries and societies. In July this year, Pangu Big Model 3.0 was officially released. Pangu Big Model has a three-layer architecture of "basic big model, industry model and scene model", which can provide basic big model capabilities such as natural language, vision, multimodal, prediction and scientific calculation, laying a solid foundation for promoting artificial intelligence to "go deep into reality" and "application innovation".

It is worth mentioning that in addition to providing Pangu big model, the Ascending AI cloud service launched by Huawei Cloud also provides an efficient, stable and well-supplied computing cloud base for open source and tripartite big models, leading the new trend of artificial intelligence technology and becoming the mainstream cloud service of artificial intelligence innovation. It is understood that the number of domestic large models is still on the rise, and all walks of life in the industry are accelerating the layout of AI large models. With the opportunity of the vigorous development of large models, Huawei Cloud has also ushered in new development opportunities.

As the key infrastructure of digital economy, "cloud" is becoming an important engine to help Chinese modernization, and "cloud service" has also become an inevitable choice for digital upgrading of enterprises. Since its establishment, Huawei Cloud has been committed to becoming the "cloud base" and "enabler" of the intelligent world, and is committed to providing users with one-stop cloud computing infrastructure services.

In the new digital era, accelerating the integration and innovation of digitalization, networking and intelligence is also the key point to promote Chinese modernization. In order to build a solid base of intelligent computing power, Huawei adheres to the strategy of All Intelligence to help industry innovation and accelerate the intelligent transformation process of thousands of industries. In terms of smart city construction, Huawei has empowered the construction of urban agents through large models, opened up the Ascending AI cloud service area, large model development tool chain and solution component ecology, and joined hands with government customers and technical partners to accelerate the application innovation of large models in government services, government offices, urban governance and other scenarios through the "Huawei Pangu Government Model Joint Innovation Action".

Help the construction of "city +AI" and promote the high-quality development of smart cities.

Taking Xiangyang as an example, in July 2013, Xiangyang Municipal Government and Huawei signed the Cooperation Agreement on Cloud Computing Data Center in Xiangyang City, which started the journey of building digital government infrastructure together. In the past ten years, the two sides have made concerted efforts and actively explored, and successfully built the leading cloud-native government cloud infrastructure in China, helping Xiangyang to comprehensively carry out information and innovation in the smart city construction system. In terms of smart government affairs, Xiangyang has deployed more than 95% of municipal government affairs applications to Xiangyang Cloud, involving more than 400 business systems run by more than 90 bureaus. The two sides have also cooperated closely in application innovation and industrial development, actively introducing partners, and creating a cloud industry ecology to help Xiangyang’s digital economy industry flourish.

Not only Xiangyang, but also Huawei Cloud has joined hands with many cities to complete the "ten-year long-distance running", deeply cultivating the construction of smart cities and leading the intelligent upgrading of cities. Up to now, Huawei Cloud has served digital projects in more than 800 cities around the world, and built "One City, One Cloud" with more than 160 cities across the country. At the same time, Huawei Cloud has also maintained rapid growth in the field of government affairs. According to IDC statistics, with its advantages in technical solutions, operational services, practical experience and ecology, Huawei Cloud has maintained the first place in the infrastructure market in government cloud, China for six consecutive years, and its innovative capabilities such as cloud native, big data and AI have been obtained.

Nowadays, the arrival of AI big model era has promoted the ecological prosperity of artificial intelligence industry, and "city +AI" has become an important part of smart city construction. Facing the new opportunity of AI big model and the new trend of "city +AI", Huawei Cloud will actively build digital people, digital cities and digital brains through four innovations of "computing power innovation, data innovation, model innovation and scene innovation" and two upgrades of "promoting security system and operation service system", which will give wings to urban business innovation, accelerate the city to a new stage of intelligence, and take "cloud +AI" as a total. This year, Huawei Cloud upgraded "One Cloud in the City 3.0" to help the city accelerate towards intelligence. Facing the future, Huawei Cloud will adhere to the core concept of "everything is service" and join hands with government customers and technology partners to go to the smart city in the new decade.

Xiaokang shares were investigated by 87 institutions: only about 8,000 SF5s were delivered in 2021, and the reason for the small delivery was mainly due to chip problems (with survey questions and ans

  () The Record Form of Investor Relations Activities was released on January 8th, and the company was investigated by 87 institutions on January 7th, 2022. The types of institutions are QFII, insurance companies, others, fund companies, overseas institutions, securities companies and Sunshine private equity institutions.

  The main contents of investor relations activities are introduced:

  First, introduce the company’s situation. Xiaokang and Huawei create a new model of deep cross-border cooperation in joint business. On April 19th, 2021, we started a mobile phone shop to buy cars. On December 23rd, Huawei released a new mobile phone and our new car at the same time, which was the first time that two smart terminals, a mobile phone and a car, were released at the same conference. The conference was a great success. It cooperated with Huawei and has a strong online digital marketing channel, especially in the core business district, which has a large number of offline store resources and is convenient for users to reach. We pursue quality delivery, adopt experiential marketing, and adopt a new sales model based on our vast offline store resources, which has a good response and strong customer purchase intention. We think this new sales model is the development trend of intelligent electric vehicles.

  Second, explain the company’s current hot topic in the market (1) Xiaokang initiated a new model of joint cross-border cooperation.

  On the question of whether Xiaokang is a foundry, we made it clear that we didn’t do it before and now, let alone a foundry. Eighteen years ago, before we entered the automobile industry, the cooperation with Dongfeng Group realized the first successful cross-border of Xiaokang shares, and Xiaokang shares did not work as a foundry. According to the strategic agreement, joint business cooperation agreement and related agreements signed by us and Huawei, we and Huawei are long-term partners. From R&D to manufacturing to delivery of automobile business, the company is responsible for R&D, manufacturing, delivery, service and creating user experience in the whole life cycle; Huawei is deeply involved in product definition, quality control and channel sales.

  The cross-border cooperation between Xiaokang and Huawei is deeply successful. The teams of the two sides have worked hard day and night and invested huge manpower and resources. Now and in the future, there is no reason for the two sides not to cooperate.

  (2) Regarding whether SF5 is discontinued:

  SF5 and Wujie M5 are both models of Celestial Company, and the company will continue to introduce new models to meet the needs of more users. As far as the company is concerned, we will not take the initiative to stop production. As long as users have demand, we will produce and deliver it. That’s the case with SF5. We will not take the initiative to stop production. The price of SF5 and Wujie M5 are different, so users can choose. We give the choice to users! Orders will be produced, delivered and served, and Cyrus will serve every car and every new and old user! Whether SF5 or M5, we will achieve high-quality delivery.

  (III) Question and answer session of investors

  Q: A new model of cooperation between Huawei and Xiaokang emerged at the end of the 21st century. Can you introduce the cooperation model in detail and how to learn from each other’s strengths?

  A: The cooperation with Huawei is cross-industry cooperation. Huawei Terminal Company is well aware of customer needs. As a mature vehicle enterprise, Xiaokang has experience in automobile research and development, manufacturing, sales and service. The cooperation between the two parties has created a precedent in the industry and produced a lot of valuable experience. This model is also the development trend and future of the smart electric vehicle industry, and it has also achieved some success. Before Xiaokang was engaged in automobile and () cooperation, Xiaokang shares crossed the border into the field of micro-cars. Since we entered this industry in 2003, there were many friends, and now there are only three enterprises left in that year: Wuling, Changan and Xiaokang. This shows that we have experience in cooperation with other enterprises, and we also have a successful experience base. Xiaokang is a modern private enterprise with high efficiency. The cooperation with Huawei over the past year has also proved the success of an efficient and standardized private enterprise mechanism. We launched a new model in March last year, and everyone saw our M5 debut in December last year. I believe that the effect of cross-border cooperation will begin to be reflected in the first quarter of this year, and batch delivery will begin in March this year. We are very confident about the sales data in the second and fourth quarters.

  The monthly sales target of the new energy automobile industry is over 10,000 yuan. We think this is the threshold sales volume of new energy vehicles in 2022, which is our goal, and the threshold sales volume will be higher in the future. At present, it usually takes a certain time for the sales of high-end electric vehicles to climb. We have full confidence and confidence in our products and channels, and hope to achieve the sales scale achieved by others in five or six years within two years.

  Q: The delivery volume of SF5 last year was less than the market expectation. What did the company think?

  A: Only about 8,000 SF5s were delivered in 2021, and the reason for the small delivery was mainly due to chip problems. The chip will affect our delivery mainly because our owner of SF5 is developed in the United States, so he uses more American electronic materials, which has been greatly affected.

  Q: Can you tell us about the follow-up vehicle planning?

  A: We have now launched the M5, and it is expected that a new large SUV will be launched at the end of the second quarter or the beginning of the third quarter in the middle of the year. I’ve been driving the M5 myself for some time, and I’m confident that it’s a car that can’t be separated once I get started. We are also developing a new large-size SUV, which will be released in 2023.

  Q: What is the pace of the subsequent launch of pure electric vehicles?

  A: There will be pure electric vehicles coming out this year. Because in 23 years, Shanghai’s extended journey can’t get a green card. Considering these market demands, we will have a pure electric version of M5.

  Q: When will the M5 be officially delivered? What is the output scale?

  A: There will be small batch delivery in February, and batch delivery will start in March. Wenjie M5 is mainly produced in Liangjiang Factory in Chongqing, which can produce 30 sets per hour, and its automation efficiency is still very high. This factory can produce 15,000 units a month. The models in the second half of the year will be produced in another factory in Chongqing, which will not affect the production capacity of M5.

  Q: Will Huawei cooperate with other car companies?

  A: Although it’s not up to us to decide who Huawei will cooperate with, our cooperation is already deep. As mentioned earlier, Xiaokang Co., Ltd. is a modern private enterprise, and its efficient and flexible mechanism is our advantage, so it is difficult for other manufacturers to reproduce it in a short time. Our cooperation is our common choice.

  Q: Why is Huawei’s self-driving system not reflected in the M5? Will it be reflected in subsequent models?

  A: Huawei’s autopilot is different from Tesla’s autopilot. Huawei’s auto-driving is vehicle-road coordination, which requires vehicle-road coordination. Without road coordination, the auto-driving of the car cannot be played out. Tesla’s auto-driving is self-adaptive auto-driving, and the road is only an aid. The contents of China’s road regulations on autonomous driving are still under study, and we also hope that China’s roads will be opened to autonomous driving as soon as possible. Auto-driving vehicle-road coordination is not only to ensure that my car does not hit the wall, but also to ensure that other people’s cars do not hit me. This high-order auto-driving technology of vehicle-road coordination is very advanced and needs time data verification. Our follow-up models will definitely have Huawei’s advanced autonomous driving.

  Q: What do you think of the present integrated die casting technology? Will you consider using integrated die casting technology for any vehicle model in the future? Is there a die casting factory or die casting machine factory in communication?

  A: It is expected that from the end of this year to the first half of next year, we will realize integrated die-casting body. Now it has entered the stage of comprehensive research and development. This technology will reduce the weight of the car body and increase the output. Because at present, the front section and the rear section are provided for welding, the technology will be integrated aluminum alloy die casting, which will greatly improve the production efficiency;

  Chongqing Xiaokang Industrial Group Co., Ltd. is a manufacturing enterprise integrating R&D, manufacturing, sales and service of passenger cars, commercial vehicles, powertrains and other automobile parts. The company currently has complete vehicle brands such as SERES, Dongfeng Scenery, Dongfeng Xiaokang, DFSK, Ruichi, etc. The main product pedigree includes SUV, MPV, mini-car and core parts. Among them, the whole vehicle products cover intelligent electric vehicles and fuel vehicles, and the core components include powertrain and three electric products with displacement from 1.5t to 2.0t..

Where is the difficulty in mass production of solid-state batteries?

    Solid-state batteries not only have high safety and high energy density, but also have excellent "high and low temperature" performance. All kinds of advantages make people look forward to them, and they are regarded as the next generation of power batteries, and also the strategic commanding heights for countries to compete. However, at present, all three technical routes have corresponding basic shortcomings that need to be solved urgently, and the cost is also an insurmountable hurdle for enterprises.

  Toyota Motor Corporation recently announced at the technical briefing that it has found good materials to commercialize solid-state batteries from 2027 to 2028 and put pure electric vehicles equipped with all-solid-state batteries on the market. However, because Toyota did not publish convincing technical details, it caused public opinion to question.

  Solid-state batteries not only have high safety and high energy density, but also have excellent "high and low temperature" performance. All kinds of advantages make people look forward to them, and they are regarded as the next generation of power batteries, and also the strategic commanding heights for countries to compete. Thirty years ago, Oak Ridge National Laboratory claimed to have built a solid-state battery, but it is a pity that it has not been mass-produced so far. In the past two years, with the popularity of new energy vehicles around the world, many companies have reported the progress of mass production of solid-state batteries, but after the news was exposed, there was no more.

  According to the material system, solid-state batteries can be divided into three technical routes. Japan and South Korea are betting on sulfide systems. In Europe, the main route is polymer, while in China, the main route is oxide. Among them, Japanese and Korean companies, represented by Toyota, Samsung SDI and Hitachi, have profound technology accumulation and obvious first-Mover advantage, and the trend of joint research and development is obvious. However, these three technical routes all have corresponding basic shortcomings that need to be solved urgently.

  Specifically, sulfide electrolyte has poor air stability, and when it is exposed to air, it will produce toxic gas. At the same time, with the destruction of electrolyte structure and the attenuation of electrochemical performance, the synthesis, storage, transportation and post-treatment of sulfide electrolyte need to rely heavily on inert gas or drying chamber. At room temperature, the ionic conductivity of polymer electrolyte is low, which makes the charging of polymer solid-state battery need to be completed in high temperature environment, which greatly limits its commercialization. Most oxide electrolytes have wider electrochemical stability "window" and better oxidation stability, but in order to ensure good interface contact between rigid oxide electrolytes and cathode materials, it is often necessary to sinter at high temperature, otherwise it will lead to serious interface chemical side reactions. In addition, some oxide electrolytes also have the problem of lithium dendrite growth.

  At the same time, cost is also a difficult hurdle for enterprises to overcome. At present, the cost of semi-solid battery is much higher than that of commercialized liquid battery. According to industry research and calculation, taking NCM811 liquid battery and NCM811 semi-solid battery as examples, the cost of semi-solid battery increases by about 80% compared with that of liquid battery. Among them, the cost of solid electrolyte is the main new cost and the main cost in semi-solid battery, accounting for about 50%. Due to the change of electrolyte material, production process and lack of experience in product quality control, the cost of all-solid battery is higher than that of semi-solid battery.

  There are five main indicators to measure whether a power battery can be mass-produced, namely, energy density, charge-discharge rate performance, cost, safety and cycle life. The laboratory research results of power batteries generally make a major breakthrough in one or several indicators at a certain stage, and it is possible to mass-produce them only when they meet the requirements of five indicators. In other words, as far as the current research and development progress of major enterprises is concerned, solid-state batteries seem to be "windy", but in fact they are "long and long", and the mass production is still quite difficult.

  Compared with structural innovation, the improvement of battery materials is slower and indeed more difficult. However, being difficult does not mean not doing it. We often say that it is reasonable to do the "difficult and correct thing". From the perspective of technological change, the technological innovation of power battery has played a major role in promoting the development of automobile electrification. The reason why China’s new energy automobile industry can lead the world is that we have surpassed the power battery, and a global power battery giant like Contemporary Amperex Technology Co., Limited was born.

  In the industrial transformation driven by the goal of "double carbon", the innovation of power battery has become the key to strengthen the competition level of new energy vehicles, build the national industrial competitiveness and stabilize the competitive advantage of enterprises. Whether it is the first country or the catch-up country of new energy vehicles, or the main enterprises of the power battery chain, they are all aiming at new technologies and laying out solid-state batteries. This is both a great challenge and a rare opportunity. Super-large-scale market advantage, leading industry-wide competitiveness and rising innovation make China more qualified to win the strategic commanding heights of power batteries.

On Guangzhou Automobile Science and Technology Day, the solid-state battery that will not spontaneously ignite was officially released!

Earlier, Guangzhou Automobile held the 2024 Guangzhou Automobile Science and Technology Day, and released the unmanned pure visual intelligent driving system and the large-capacity all-solid-state power battery, both of which are the leading technologies in China.

No-graph pure vision intelligent driving system

We all know that most of the intelligent driving systems on the market at present are based on high-precision maps, but one problem with high-precision maps is that they are slow to update and have poor adaptability to complex road conditions such as sudden road repairs.

The intelligent driving system without map and pure vision is like giving a car "eyes", completely getting rid of the dependence on high-precision maps and perceiving the world like a human being. There is no complicated lidar, and a more concise and low-cost hardware system is used to realize a wider range of intelligent driving experience. At the same time, the intelligent driving system without map and pure vision also has the ability of continuous improvement and self-improvement and progress.

However, in my opinion, there are still limitations in the unmanned pure vision intelligent driving system. For example, in a thunderstorm with low visibility, or in the face of such an emergency as a "ghost probe", the pure vision scheme has the same visual blind spot as the human eye. Therefore, I personally guess that in the future, "multi-sensor fusion technology" and "map-free pure vision technology" will coexist, and they will not replace each other.

The unmanned pure vision intelligent driving system will be installed on the family car at a lower cost, so that the users of the family car can also have high-level intelligent driving, while the high-end models are still lidar+vision solutions. This technology will be officially loaded in 2026.

Large-capacity all-solid-state power battery

In addition to the unmanned visual intelligent driving system, another black technology is all-solid-state power battery. At present, the expected loading time of all-solid-state power battery in the industry is in 2030, and GAC announced that they plan to complete the loading of all-solid-state power battery in 2026, which is much faster than the industry standard.

So what are the advantages of all-solid-state power batteries? Its biggest advantage is that it increases the energy density of the battery and reduces the risk of spontaneous combustion.

According to the official information, the negative electrode adopts the third generation sponge silicon negative plate technology, that is, the "silicon" material, while the positive electrode adopts the solid-state positive electrode technology with high surface capacity, but the electrolyte that everyone is very concerned about has not been announced.

The overall energy density can reach more than 400Wh/kg, which is not particularly high. After all, Contemporary Amperex Technology Co., Limited has released a battery with a single energy density as high as 500Wh/kg before. Personally, it is expected that GAC will deliberately reduce the energy density for safety reasons.

According to the official data, the all-solid-state power battery of GAC does not explode in the hot box test at 200°C, and can maintain stable performance under extreme conditions such as-78°C dry ice and 90°C high temperature.

The announcement of these two technologies represents that GAC is continuing to deepen their technical strategy and demonstrates the strong R&D and innovation capabilities of GAC Group. However, the actual performance will not be known until the actual loading has been tried.

Chinese scientific research team found a new way to improve the performance of all-perovskite laminated solar cells

  Xinhua News Agency, Wuhan, November 12 (Reporter Hou Wenkun) After long-term research, Professor Ke Weijun and Professor Fang Guo from the School of Physical Science and Technology of Wuhan University have made new progress in exploring the performance improvement of all-perovskite laminated solar cells, and creatively put forward the integrated doping strategy of aspartic acid hydrochloride, which effectively improved the efficiency and stability of narrow-band gap perovskite subcells and found new ways to further improve the battery performance. Related research results were recently published in the journal Nature.

  According to reports, the new metal halide perovskite has the advantages of simple preparation process, high defect tolerance, high absorption coefficient and long carrier diffusion length, which has attracted much attention in the field of optoelectronic devices and is considered as one of the next generation photovoltaic materials with great prospects in the industry.

  Ke Weijun, one of the authors of the paper and a professor at the School of Physical Science and Technology of Wuhan University, said that in practical application, the all-perovskite laminated solar cell is composed of a broad-band gap perovskite subcell at the top and a narrow-band gap perovskite subcell at the bottom, and the narrow-band gap perovskite subcell that is not excellent enough is one of the stumbling blocks for its commercial application in the future.

  To this end, the research team introduced aspartic acid hydrochloride into the hole transport layer, perovskite light absorption layer and upper interface layer at the bottom of all perovskite laminated solar cells, and developed an integrated doping strategy with the same molecular treatment, which greatly improved the quality of perovskite thin films. In addition to coordinating with perovskite precursors, aspartic acid hydrochloride molecules also have strong intermolecular hydrogen bonds, so aspartic acid hydrochloride enriched at the upper and lower interfaces of perovskite acts as a molecular lock between the interface of perovskite layer and transport layer, further improving the performance and stability of perovskite materials.

  In addition, how to inhibit the spontaneous oxidation of unstable divalent tin metal ions in narrow-gap perovskite subcells is also one of the pain points in the industry. The results show that aspartic acid hydrochloride can effectively inhibit the oxidation of divalent tin ions and reduce harmful tetravalent tin impurities. Moreover, the introduction of aspartic acid hydrochloride can also passivate the defects of perovskite materials, adjust Fermi level and inhibit harmful ion migration, thus enhancing the performance and stability of devices.

  Ke Weijun said that the research shows that this simple integrated doping strategy can achieve multiple functions at one stroke and improve the steady-state efficiency of narrow-band perovskite subcells to 27.62%, which provides a new way to improve the performance of all-perovskite stacked solar cells.

Mermaid sadism! What’s the story of Stephen Chow’s The Mermaid?

    Special feature of 1905 film network On January 31st, The Mermaid, which will be released on the first day of the New Year’s Day, held a conference of "Fish, Water and Acacia" in Beijing. Director Stephen Chow made a collective appearance with the mighty "Mermaid Family" and released a trailer of the final version for 1 minute and 40 seconds.

    This highly anticipated film has maintained a mystery so far, and has always adopted the hunger marketing route, without any screening and media watching activities in advance. It is really hard to say whether Master Xing is too confident or too unsure about the quality of this film.

    We can only get a glimpse of several groups of film materials exposed at present.


1. This movie is very Stephen Chow.

Stephen Chow is not only the king of comedy of the performing world, but also the film he directed is unique. Starting from "Demon Journey to the West", he no longer arranged a place for himself in the film, but hid behind the monitor as a director.

Inner OS: What the hell is it? …

    The first time we heard that there was no Stephen Chow in a Stephen Chow movie, we felt a little sorry in our hearts. However, when we saw The Demon on a Journey to the West, we were surprised to see the familiar shadow of cynicism in the article, Bo Huang, Show Lo and even Shu Qi’s role.

    After a lapse of three years, there will be no guest appearance of Master Xing in The Mermaid, but through the director’s special feature exposed by the film, it can be found that his director’s way is to completely instill his performance into the actors, even at the expense of repeatedly demonstrating in person, in order to accurately meet his requirements.

Demonstrate and guide the actors to perform in person.

    So, even if Master Xing doesn’t appear in the movie, we don’t have to worry. "Mermaid" is definitely a film that inherits Stephen Chow’s strong personal style. There are all kinds of nonsense, cold humor, man show and madness in it, and every one is guaranteed.

2, the character has a big bottom and an N angle, which is related to mermaid sadism

    There are quite a few familiar faces in this movie. From the trailer currently exposed, we see Deng Chao, Show Lo, Yuqi Zhang, Jelly Lin, Li Shangzheng, Lu Zhengyu, Yang Neng, Ke Bai, Kong Lianshun, Wu Yifan, Wen Jian, Zhang Mei ‘e, etc., and all the immortals show their magical powers — — Of course, most of them are "dead walk-on".

For example, this:

Yang Neng, the "Pork Guy" in shaolin soccer, turned into the curator of the World Museum of Rare Animals in The Mermaid, and personally performed it for a group of tourists — — "Our ancestors were all fish."

There are also two police comrades who were exposed in the first preview, whose painting is "super good" and their understanding ability is "first-class", which were played by Tang Priest’s article and Friar Sand Li Shangzheng in "Demon Journey to the West" respectively.

Even Wu Yifan, a guest star, got a glimpse in the final trailer — — Look at the dress, you should be a rich second generation.

However, there is a role that has not been revealed so far, and that is "Master" Tsui Hark! At the press conference held yesterday, not only the "Mermaid Family" was all out, but also an old friend of Xingye, Tsui Hark, was invited, and he was revealed to have a guest performance in The Mermaid. "There are more than one line."

Master Xing also said with a smile: "Tsui Hark’s acting skills are very good. In fact, the director who can act best, I think one is Director Xu and the other is me. There is nothing to say about acting skills."

Two "old urchins" were funny at the press conference.

Of course, the most important roles in the film are the four donkey kong — — Octopus, mermaid, sea urchin and … … Lettuce?

Deng Chao: The hero of the film is a wealthy real estate developer and local tyrant. In Stephen Chow’s words, this character is a baby at heart, and his beard is his disguise. He wants to pretend to be a mercenary adult. Deng Chao himself explained it in Deng Shiying at the press conference as — — The beard is a ghost, and the beard is an angel.

Angel’s affection

Ghost’s evil (it should be evil … Xueba’s English is not flattering.

Jelly Lin: The mermaid, the heroine of the film, was forced to live in a wrecked ship because of the destruction of the sea and ecology by human beings. Deng Chao, who entered human society in disguise and used love to influence the development of marine resources, didn’t expect that he actually fell in love with him.

A tearful French kiss

Show Lo: Playing octopus is also a marine creature (nonsense). He has always loved the mermaid. When he found that "the person I love has a lover", he was very sad and tried to kill his rival with his tentacles. With eight giant tentacles, he can be regarded as the main fighting force of the mermaid gang.

Yuqi Zhang: Playing Deng Chao’s ex-girlfriend. Not only does she look like an overbearing female silver, but she is also the villain in the film — — The kind that is completely bad. She herself summed up this role as a "synthesis of violence and aesthetics" — — I am beautiful, but I am not gentle.

Mysterious mermaid: In the last fierce battle of the final preview, the amazing mermaid tail on the trailer and poster appeared again. Compared with Lin Yun’s small tail, this fishtail with colorful light has a powerful ability. When flapping the sea, it is "the four seas churn and the five continents shake and thunder". Judging from the expressions of fear on the faces of mermaid and octopus, adult fish should be the villain in the film. Yuqi Zhang, Lenovo’s villain, had a strange look at the little mermaid in the preview … … Murphy, Deng Chao breath even made two mermaid girlfriend? (This doesn’t seem to be the point … …

But if you zoom in carefully, the mermaid’s upper body seems to be a long-haired man in a white shirt, which is a bit similar to Yang Neng’s image.

How big is Master Xing’s brain hole? The answer can only be revealed after the film is released.

3. The main line of the story is positive energy

If you think this is a story that he loves her, she loves him, he loves her and doesn’t love her, and she loves him and doesn’t love him, then you are too young (fu) and childish (qian). You told us at the very beginning of the trailer that this is a tall environmental propaganda film!

Mermaids and humans should have lived in peace. Who knows, the more they progress, the more violent they become … …

Xuan Shao, played by Deng Chao, was originally a mercenary businessman. The development of real estate involved reclamation projects, which threatened the ethnic groups living in the sea. Jelly Lin’s mermaid Sam was sent to stop her. She turned into a human being, and fell in love with Xuan Shao in the process of fighting, and finally succeeded in stopping the whole project and protecting her home.

From this stills, we can also see that mermaids are covered with all kinds of rubbish and waste in the sea.

At the end of the trailer, it also echoed the theme:

If your life is only the last minute, if there is not even a drop of clean water and a breath of clean air on the earth, what do you want to do most?

In addition, we also saw a very familiar line in the previous trailer:

Isn’t this just a salted fish?


If you don’t have a dream, what’s the difference between being a man and salted fish?

It’s a tribute to the previous work.

The Birth of the Song "I Dedicate Oil to the Motherland"

Qin Yongcheng’s "First Oil Well" in Daqing Oilfield. Pictures are data pictures.

Qin Yongcheng (right) is with oil workers in Panjin Oilfield. Pictures are data pictures.

  [Great motherland, unforgettable songs].

  "Splendid rivers and mountains are picturesque, and the motherland is building a cross-horse. It’s a great honor for me to be an oil worker and travel around the world wearing an aluminum helmet … …” This heroic ode to oil workers is not only a clarion call to encourage oil workers from generation to generation to join in the construction of the motherland, but also an overall portrayal of the outstanding heroes of the working class in China. Although it was written more than half a century ago, it is still so exciting and exciting to sing today.

  The composer Qin Yongcheng (1933— 2015) is the first generation composer trained in New China. During more than half a century’s creative career, he has created a large number of musical works with high artistic achievements and wide social influence, such as the song "I offer oil for the motherland", "Chairman Mao travels all over the motherland", My People,My Country, vocal concerto "Haiyan", symphonic poem "Two Little Cowboys" and movie music "Entrepreneurship" and "Marshal and Soldiers". He made great contributions to the music, art and education in our country all his life.

  Three days with the "Iron Man"

  In 1964, a notice brought Qin Yongcheng into close contact with Li Jiefu, a famous composer and president of Shenyang Conservatory of Music. It was this notice that made him have an indissoluble bond with oil workers all his life. In March this year, China Musicians Association organized some composers to experience life in Daqing Oilfield and created a batch of works reflecting oil workers. Dean Hijacking also received a notice, asking him to report to Sarthou, Heilongjiang Province on March 20th. After receiving the notice, the dean of the robbery immediately made preparations for leaving. Due to physical reasons, the college is going to find a young man to accompany the dean of the robbery to "go north". At the suggestion of the dean of the robbery, Qin Yongcheng will accompany him. Unfortunately, Qin Yongcheng was suffering from a high fever and had been in bed for three days. Upon hearing this, Dean Hijacking personally visited Qin Yongcheng’s home and told him to rest at ease for illness. In the face of this rare opportunity, Qin Yongcheng looked forward to his early recovery. Although his fever had gone down the next day, he was still very weak, and insisted on accompanying Dean Jiefu.

  On the evening of 19th, Qin Yongcheng got his wish and boarded the train to the north. In the car, Qin Yongcheng finally put forward the question that was hidden in his heart: "Where are we going to Sarthou?" Dean Hijacking told him quietly: "Sarthou is a big oil field, called Daqing Oilfield, and it is still confidential." After moving to Daqing, Qin Yongcheng lived with many famous musicians such as Lv Ji, Qu Wei, Wang Xin, Zhang Lu and Jiefu in the guest house of Daqing Petroleum Command.

  Since the next day, the oil field has arranged courses for musicians to introduce oil-related knowledge, from exploration and drilling to oil production and refining for ten days, with one content per day. Ten days later, the oilfield arranged for them to experience life in the first line. Qin Yongcheng, Jiefu and Wang Xin (songwriters of "Singing the Motherland") were assigned to the "1205 Hero Drilling Team" with Wang Jinxi, the "Iron Man", and lived together with the "Iron Man" for three days. During this period, Wang Jinxi told Qin Yongcheng that when he held a People’s Congress in Beijing in 1959, he saw that the buses in Beijing were in a heavy mood because of lack of oil and carrying gas bags. He also listened to him tell the story of the Daqing Petroleum Congress. In the spring of 1960, Wang Jinxi’s drilling team was in Yumen Oilfield. When it was heard that a large oil field had been discovered in the north, the whole country was going to hold a general meeting there, and immediately asked the superior to fight. They said goodbye to their relatives and boarded the train going north in their light clothes. Faced with the harsh climate, hard living and working environment, and poor equipment, oil workers shouted the loud slogan of "if you have the conditions, you should go if you don’t have the conditions" in order to get rid of the label of "poor oil" as soon as possible and break the economic blockade of western hostile forces. "When the oil workers roar, the earth will shake three times."Qin Yongcheng’s soul was strongly shocked and greatly impacted by his earth-shattering fearless revolutionary heroism. Especially in the days spent with Wang Jinxi and his heroic drilling crew, Qin Yongcheng’s understanding of oil workers has been greatly sublimated, and he has a strong emotional resonance. He is determined to create works that can reflect the spirit of oil workers to express his high respect for them.

  A masterpiece completed in the canteen of the hostel.

  After three days of experience, Qin Yongcheng returned to the guest house, and the Propaganda Department of the Party Committee of the Oilfield prepared a batch of lyrics reflecting the work and life of Daqing Oilfield and oil workers for them, hoping that composers would compose music for them. After the old composers had chosen the lyrics, Qin Yongcheng also chose them. At this time, a lyric jumped into his eyes, which was written by oil worker Xue Zhuguo, "I offer oil for my motherland." This first-person lyric is vivid and vivid, which vividly depicts the heroic and optimistic mood of oil workers and the fearless revolutionary spirit of fighting against the world. The more Qin Yongcheng watched it, the more he liked it. The more he watched it, the more excited he became. At this moment, he was inspired and full of thoughts. In the canteen of the hostel, he finished writing this work in just 20 minutes.

  Inspired by the artistic conception of the lyrics, the prelude of the song adopts a fast speed, a lively and elastic rhythm, and a fluctuating melody line, like a train full of oil workers galloping in the splendid rivers and mountains of the motherland, from the northwest of the motherland to the northeast thousands of miles away. Then, the heroic song of the oil workers was introduced: "The beautiful rivers and mountains are picturesque, and the motherland is building a beautiful horse. I am honored to be an oil worker and wear an aluminum helmet to travel all over the world." The melody of the song is broad, fresh and smooth, which vividly depicts the bold spirit of oil workers and the revolutionary optimism full of pride and self-confidence. On the word "kua" of "kua steed", the melody absorbs the elements of rap music and adopts a sliding tone, which is not only in line with the rhyme of Chinese four tones but also forceful, and can better highlight the bold and hearty character of oil workers. These four sentences are lyrical paragraphs, which vividly depict the heroic fighting spirit and optimistic spirit of oil workers moving to the north and south and being at home all over the world.

  In order to show the dauntless heroism spirit and heroic spirit of oil workers, who are "fearless of heaven, fearless of earth, and fearless of storm, thunder and lightning", Qin Yongcheng treated these two lyrics into short and powerful eight-point dotted notes and syncopated rhythm, which made the music more powerful and dynamic. At the same time, it not only forms a sharp contrast with the previous lyric paragraphs, but also lays a good foundation for the climax of the whole song that appears later.

  The climax of the song is in the last two phrases, "I contribute oil to my motherland, where there is oil, my home is there". In order to make the climax of the song more prominent and infectious, Qin Yongcheng ingeniously treated the first beat at the beginning of this sentence as a rest, and started the word "I am" from the weak beat to highlight the word "ancestor" in the next section. Then, on the word "oil" for "offering oil", the melody adopts a circuitous upward movement, forming a large-span 10-degree interval in the range. In the last four bars of the song, Qin Yongcheng skillfully used the drawl of China’s traditional opera music for reference. It is worth mentioning that in the first draft of the work, the last four sections are not like this, but after Qin Yongcheng returned to school, he sang the work to friends and students, listened to and adopted everyone’s suggestions, and changed the original last simple melody into the current one-stop drawl. In this way, the music is more infectious and dynamic, which not only depicts the free and easy character of oil workers, but also makes the whole song end in an atmosphere full of optimism and pride. The revised work was published in the journal "Music Life" of Liaoning Branch of China Music Association, which soon became a hero’s ode to oil workers in the north and south of the motherland and inside and outside the Great Wall.

  The only "composer of oil workers"

  The first singer of this song, Liu Bingyi, a famous baritone singer of the former Central Orchestra, also played an important role in the promotion of this song. He and Qin Yongcheng also became attached to this song, and it was sung for 50 years. And Qin Yongcheng also started from this song, and successively created a number of excellent works reflecting oil workers. In 1973, as a key project of the Ministry of Culture, Changying filmed a feature film "Entrepreneurship" reflecting the Daqing Petroleum Congress, and specially invited Qin Yongcheng to create music for this film. Qin Yongcheng lived up to expectations, and created a number of well-known songs in his film music, such as Looking at Beijing with deep feelings, Entrepreneurial songs, and The Fragrance of Oil in Tianya Wan Li. Because of Qin Yongcheng’s outstanding contribution to the creation of oil-related music, the vast number of oil workers are familiar with the name Qin Yongcheng and affectionately call him "the composer of oil workers". In 1994, China Petroleum and Natural Gas Corporation (formerly the Ministry of Petroleum Industry) awarded Qin Yongcheng the honorary title of "composer of oil workers", and he was the only composer in China to win this honor. In 1996, China Records Corporation awarded Qin Yongcheng the "Golden Record Award" for this work, which was later included in the 20th century Chinese classics.

  Praising the motherland and people and eulogizing the times and life are the themes of Qin Yongcheng’s life creation. It is precisely because of Qin Yongcheng’s deep patriotism, deep thoughts and feelings for the broad masses of the people, including oil workers, rich musical language based on Chinese excellent musical culture, and continuous absorption of rich nutrition and creative sources in the long-term in-depth social life that he created such immortal masterpieces represented by "I Contribute Oil to the Motherland", which are full of positive energy and the main theme of the times, and have high artistic value and appeal to both refined and popular tastes.

The rapid development of artificial intelligence opens up new employment space

CCTV News:At the Nishan Dialogue Conference on Digital Civilization, the participating experts also discussed the new employment space brought by the development of artificial intelligence. Experts said that with the growing industrial ecology with artificial intelligence as the core, it has injected new impetus into China’s economic development, and at the same time, a large number of new career needs have emerged, opening up new employment space for more young people.

AI pinch face algorithm engineer Wu Jiayang:This is our intelligent face kneading interface, and we can support face kneading through image input and text input.

His name is Wu Jiayang, and his occupation is AI face-kneading algorithm engineer. With the rise of new formats such as Metauniverse and online games in recent years, a professional "face-kneading teacher" has been born, which is to help users create online virtual images with personal characteristics.

AI pinch face algorithm engineer Wu Jiayang:Many players actually want to have a virtual image that is highly similar to themselves in the game or meta-universe, so we can generate a character that is very similar to ourselves by uploading our own photos here. It can make every user feel very immersed in the game, as if he is also there.

In the latest list of new occupations published by the Ministry of Human Resources and Social Security, virtual architects are also impressively listed. At present, this latest occupation is no longer limited to the field of meta-universe and online games, and its service field has been expanded and extended.

Virtual Architect Zou Yi:Virtual space is still widely used now.ofFor example, enterprises, they will need to build their own 3D enterprise space, and then there will be some exhibition conferences. In the case of cultural tourism, such as museums, these scenic spots offline will also have a virtual space online, so the scope of application is very wide.

It is understood that with the development of artificial intelligence technology, some new occupations with relatively low professional threshold are constantly being born, such as data annotators and artificial intelligence trainers, which have now become popular occupations.
