"I accidentally stepped on shit when I was walking, and I happened to have an injury on my foot. Do you want to get rabies vaccine?" You must want to know such a wonderful question. "After the baby is vaccinated, why do you have to wait for 30 minutes to leave the hospital?" You must be very concerned about such common problems. "With HPV vaccine, you can stay away from cervical cancer once and for all?" You must not miss such a hot question.

　　At the final of "Guangzhou Vaccination Science Popularization Competition in 2020" held recently, all kinds of knowledge about vaccines and vaccination made people learn a lot.

　　The birth process of vaccine is not simple.

　　Since ancient times, human beings have been fighting against viruses, and have gradually discovered the magic weapon to win — — Vaccine. There are several ways to produce vaccines, one of which is — — Take inactivated vaccine as an example to talk about the birth of vaccine.

　　First of all, scientists should isolate the virus from the source of infection. The isolated virus can not be used directly, and it needs to be processed before screening out the ideal strain. Then these strains are cultured and propagated on the cell matrix; These strains contain some impurities, which need to be removed by filtration. Then treated with formaldehyde and other solutions to make the strain lose its pathogenicity and retain its antigenicity; Finally, through a series of processing, inactivated vaccine can be born.

　　But this vaccine can’t be injected into human body at this time. In order to ensure safety and effectiveness, the vaccine needs to undergo strict tests at different levels. The first level is the animal test. After passing the animal test, it can be reported to National Medical Products Administration to apply for clinical trials. The clinical trial is divided into three phases. This is for the sake of safety, and the test population should increase in a step-by-step manner. Only after the safety of the first-phase clinical trial is ensured can the second-phase clinical trial be carried out to study its effectiveness. In the last three phases, a randomized, blind and placebo-controlled design should be adopted to comprehensively evaluate the effectiveness and safety of the vaccine in a wider range of people. All clinical trials generally take at least 3-8 years, and some even take more than 10 years. If the vaccine fails to meet the requirements in the test, it will be stopped or even terminated.

　　After passing the above-mentioned layer-by-layer tests, it is necessary to go through enterprise self-inspection, expert review, on-site inspection by the Food and Drug Administration, and identification by the Central Inspection Institute to confirm that the vaccine is safe and effective, the process is true, and the quality is controllable. At this time, the vaccine can be officially marketed and promoted.

　　Today’s children have been vaccinated to prevent various diseases shortly after birth. One of the most common phenomena is that babies are usually asked not to go home immediately after vaccination in the hospital, and can only go home after observation in the observation room for at least 30 minutes. Why is this? Is there anything unsafe about the vaccine? In fact, adverse reactions may occur after vaccination, but the probability of occurrence is very low. There are two kinds of adverse reactions, one is a relatively common general reaction, such as fever, redness and swelling at the injection site, poor appetite, etc. There is also an abnormal reaction, which means that the vaccine is qualified and the vaccination process is standardized, but it has brought some damage to the baby’s body. Both of these reactions belong to "adverse drug reactions with no fault on both sides".

　　If the baby’s body temperature does not exceed 38℃, you can use the method of physical cooling and pay attention to rest to return to normal; If the inoculation site is red, swollen and indurated, it is generally not necessary to deal with it, and special attention should be paid to it. It is forbidden to apply hot compress after inoculation with BCG. If the baby’s temperature exceeds 38℃ or the general reaction is serious, you should seek medical treatment immediately without delay.

　　Therefore, don’t go home immediately after vaccination, also for "just in case".

　　There is no need to get rabies vaccine when you step on shit when you have a foot injury.

　　When a Panyu player popularized the vaccination of rabies vaccine, he mentioned a new knowledge point that people didn’t know much about before: if a dog bites you, you can observe the dog for ten days. If the dog doesn’t get sick, then the remaining shots of rabies vaccine that we have started to vaccinate don’t need to continue.

　　We know that 95% of rabies in China is spread by sick dogs, followed by some carnivorous mammals, such as cats, bats, foxes, wolves and raccoons. Cold-blooded animals such as poultry, fish and insects will not infect and spread rabies. You don’t need rabies vaccine after being bitten by rodents, rabbits and rabbits. Infectious diseases of dogs, cats and other animals are usually spread to them by external animals. Once a cat or dog is bitten by an infectious animal, the incubation period of the virus in their bodies is generally more than one month, but only in the saliva of the cat or dog 3-5 days before the onset of the disease may rabies virus be carried. Therefore, for some cats and dogs that are confirmed to be healthy, such as domestic cats and dogs that have a clear history, are not free-range or wandering, have never been bitten by animals suspected of rabies, and have been regularly injected with rabies vaccine, it is not necessary to take rabies vaccine when bitten by these cats or dogs.

　　Someone asked, "I accidentally stepped on shit when I was walking, and I happened to have an injury on my foot. Do you want to get rabies vaccine?" In fact, there is no need to get rabies vaccine. But it is best to clean the wound in time to prevent infection by other germs.

　　However, most people are not sure whether the biting animal is healthy after being bitten by an animal, so it is certainly right to think of vaccination at the first time. However, the rabies vaccine needs 5 shots in the whole process, and there is an interval between every two shots, so it not only costs money, but also takes time. Here is a "ten-day observation method" worthy of attention — —

　　First of all, for peace of mind, you can get vaccinated first, and at the same time lock up the biting dog for observation; If the dog is still very healthy after ten days, which proves that the biting dog was not in the period of rabies infection at the time of the incident, then you don’t need to take the rest rabies vaccine. If the dog is abnormal during the observation period, then your vaccine must be finished.

　　Vaccination with HPV vaccine is not 100% away from cervical cancer.

　　Like "settled" in the female cervix of the HPV virus, the scientific name is human papillomavirus, which is the chief culprit leading to cervical cancer. According to the ICO (Catalan Cancer Institute) report on HPV and related diseases in China released in 2018, 98% of cervical cancer in China is caused by high-risk HPV infection. There is no specific medicine for HPV infection at present. However, human beings have developed an HPV vaccine. After vaccination, the body can produce antibodies to eliminate high-risk HPV, thus preventing cervical cancer.

　　It has been known that there are more than 200 family members of HPV virus, and only 14 species can really "make waves" on human cervix. These fourteen kinds are called high-risk HPV, among which HPV16 and 18 are the most powerful, and 69% of cervical cancer is attributed to them.

　　At present, the HPV vaccines on the market are bivalent, bivalent and bivalent. If you hit the price of 2 and 4, you can prevent about 70% of cervical cancer; The tetravalent vaccine can also prevent 6/11 types of 14 high-risk HPV, which can prevent sexually transmitted diseases caused by these two types of viruses; On the basis of 4 valence, 9 valence has the function of preventing 31/33/45/52/58 type, which can prevent 92% of cervical cancer. The ideal vaccination time of HPV vaccine is before sex, that is, before the first exposure to HPV infection, but women who have had sex can also benefit from HPV vaccination.

　　Why does HPV appear in the human body? Mainly through sexual behavior, or contact with unclean sanitary ware or supplies. It is worth noting that women who are sexually active and have many sexual partners are particularly vulnerable to infection. But not being infected with high-risk HPV means getting cervical cancer. Only when high-risk HPV is continuously infected for 10 to 20 years will it naturally evolve into cancer. In this process, most people’s body functions can remove HPV.

　　It is worth reminding that the HPV vaccine is not once and for all. The HPV virus family is "numerous", and about 7% of cervical cancer can not be prevented by vaccination with HPV vaccine for the time being. So if you are old enough to have regular screening for cervical cancer, you should remember to have regular screening. If HPV vaccination is the primary prevention of cervical cancer, regular cervical cancer screening is the secondary prevention. Only when primary and secondary prevention are done, the "big devil" of cervical cancer will not be easily encountered. (Yangcheng Evening News reporter Li Gang)

　　The National Day holiday is coming to an end, and the consumer market is booming, showing new characteristics.

　　Wang Bin, deputy director of the Consumption Promotion Department of the Ministry of Commerce, said that this year’s National Day holiday consumption has highlighted four major trends compared with previous years, namely, local consumption, peripheral consumption and home consumption have become new hotspots; Green consumption, smart consumption and healthy consumption are more popular; The demand for personalization and quality has increased, and the heat of high-end consumption has not decreased; Online and offline integration will be accelerated, and the demand for experiential and scene-based consumption will continue to increase. "Consumption will continue to recover steadily in October and even throughout the fourth quarter. It is estimated that the total amount of social zero in the whole year is expected to reach 44 trillion yuan, an increase of about 12.5% over 2020 and an increase of about 8% over 2019. " Wang Bin said.

　　Products with high quality and beautiful price, convenient and fast service and rich individual experience will accelerate the release of consumption potential and foster a more active and stronger consumer market.

　　Buy and produce texture

　　Products are better and services are more intimate.

　　"During the National Day holiday, the sales of flowers increased significantly." The person in charge of the procurement of Box Horse Garden said that decorating life with flowers has become one of the ways for consumers to improve their quality of life. "We stocked a lot of tulips through the Yunnan base before the festival. The first batch of tulips were of high quality and sold well. They were sold as soon as they were listed, and hydrangeas and sunflowers were also very popular." From October 1 ST to 4 th, the sales volume of flowers in Box Horse Garden increased by 290% year-on-year.

　　Ensuring the quality of goods is the most basic demand of consumers. In order to improve the quality, some supermarkets have made more efforts in market research, product procurement and even research and development, and strive to introduce more fine products and "explosions".

　　"This portable tooth washer is selling well at present. The domestic oral care market has grown rapidly, and the oral care products of the public have been upgraded from toothbrushes and dental floss to electric toothbrushes and tooth flushers. " Zhu Lin, general manager of Tmall Personal Care Department, said. The sales of consumption-upgrading products such as cosmetics, electronic products and personal care products in major e-commerce platforms maintained rapid growth.

　　In a Gome store in Haidian District, Beijing, the reporter saw that many consumers came to consult the "old for green" activity. "We jointly launched an activity with air-conditioning companies to replace the air conditioners eliminated in users’ homes with new energy-efficient standard air conditioners, and the number of consumers who went to the store for consultation and purchase during the National Day holiday increased significantly." The relevant person in charge of the store said, "In the past, people paid more attention to the price. In recent years, with the upgrading of consumption, energy-saving, smart and healthy home appliances are more popular. "

　　Zhao Ping, vice president of the China Council for the Promotion of International Trade Research Institute, said: "At present, the pace of upgrading China’s consumption structure is accelerating. On the one hand, commodity consumption is upgrading from low-end to high-end, on the other hand, commodity consumption is also upgrading to service consumption. "

　　Commodities like flowers need merchants to have good fresh-keeping storage conditions, fast logistics and transportation capacity and meticulous after-sales service. "When sent with flowers, there are often detailed maintenance instructions." A consumer who often buys flowers, fruits, seafood and other goods online said that if the quality of the goods is not good, he will immediately apply for a return, and Shangchao often responds quickly and makes a refund or compensation.

　　The relevant person in charge of public comment analyzed the data and found that the service quality played an obvious role in driving the sales of offline businesses. Zhao Ping believes that as China’s consumption scale continues to expand, it is necessary to further improve the supply quality of products and services, organically combine expanding consumption with improving people’s quality of life, promote the creation of a high-quality consumption supply system, and guide enterprises to increase the supply of cost-effective goods and services to better meet the high-end consumer demand of residents.

　　Buy a new experience

　　The scene is richer and the atmosphere is more immersive.

　　Today, online shopping is convenient and fast. Where is the charm of offline shopping?

　　During the National Day holiday, in the National Cultural Industry Demonstration Park of Nanbin Road, Nan ‘an District, Chongqing, the exhibition of the former Art Museum attracted many citizens to visit. "I heard a long time ago that sneakers jointly designed by artists and brands will be exhibited offline here." Liu Zikai, 21, loves collecting sneakers. "We sneaker lovers have been waiting for a long time."

　　Liu Zikai said: "Through the visit, I have a deeper understanding of the design and cultural expression of these shoes. I must buy some pairs to collect at home."

　　In addition to co-branded sneakers, you can also buy masks, scarves and other commodities with the same theme on the spot. Many citizens bought several pieces after watching the exhibition. "If we only sell handicrafts, it will be too far away from ordinary consumers, so we set up a cultural and creative product exhibition area on the first floor." According to the relevant person in charge of the former Art Museum, different from the traditional business model, they have explored in the field of art consumption, and many brands will choose to release their products here because many consumers like unique experiences.

　　At the other end of Nanbin Road, Bainian Old Street just held an autumn and winter clothing conference. "Nowadays, a single consumption environment can no longer meet the needs of customers, and we hope to involve consumers." The person in charge of the event said that in addition to online live broadcast, the site also provided services such as follow-up and styling design. For example, on the day of the event, they invited 10 customers to walk on the catwalk, and Ms. Zhang was one of them. "In the century-old street, wearing fashionable clothes and showing yourself under the rhythm of music and lighting is very special, and some things are still unfinished." Ms. Zhang said.

　　Nan ‘an District, by establishing Nanbin Road National Cultural Industry Demonstration Park, is trying to promote the organic integration of characteristic cultural resources and cultural industries, cultivate new cultural formats and cultural consumption patterns, and build Nanbin Road into a highland for cultural industry transformation and upgrading.

　　"In recent years, experience has become an increasingly important factor for consumers." Mo Yuanming, a researcher at chongqing technology and business university Chengdu-Chongqing Shuangcheng Economic Circle Collaborative Development Center, believes that the market is actively responding to this new demand. Integrated development is becoming a new consumption trend, that is, through the integration of culture and tourism, economy and technology, consumption and culture, to create a brand-new comprehensive consumption carrier. "To promote the development of the retail industry, it is particularly important to shape new consumption scenarios. Through integration and experience, the organic combination of retail, cultural industry and service industry is the essence of shaping new consumption scenes. " Mo Yuanming said.

　　Buy out personalization

　　The demand is more unique and the market is more subdivided.

　　A trendy shop in Zhengjia Square, Guangzhou, Guangdong Province was crowded, and the trend toys with "Chinese style" were placed in the exhibition area, which attracted many guests to stop and take photos. Zeng Qingyuan was one of them. After careful selection, he picked up a cat ornament and prepared to check out. "It’s festive and beautiful, and it’s cool at home."

　　Mr. Lin, who lined up behind Zeng Qingyuan, bought building blocks with children who were in the fifth grade. "Children liked the movie The Wandering Earth before, and now they have the building blocks with this theme, and he immediately took a fancy to it."

　　"We are promoting the Guofeng Building Block Festival, cooperating with domestic designers to design local building blocks, and introducing them to consumers more intensively through the combination of stores and exhibitions." Cai Jianping, the store manager, said that these products were sold out soon after they went online, and many guests made a special trip to ask when to replenish them.

　　Some people like chasing trendy toys, while others like visiting thrift stores. In Chaoyang District, Beijing, Li Bo, a citizen, used his holiday to shop at the limited-time second-hand shop in Sanlitun. Here, you can find second-hand books and many second-hand clothes in various fields. There is also a tailor shop in the shop. "If you find the clothes you like, you can change clothes for free on the spot if it is not suitable." Li Bo said. A consumer said that in addition to meeting the needs of environmental protection, second-hand shops can often bring the pleasure of "treasure hunting", such as finding other people’s reading notes in books, as if they were communicating with the last reader across time and space.

　　Whether it is a trendy shop or a second-hand shop, or a variety of special live broadcast rooms, we can see that the market is showing a segmentation trend in a more colorful state, making it easier for consumers to meet their individual needs.

　　It is worth noting that the emerging new formats and new fields need more in-place supervision.

　　"For example, in the second-hand commodity market, sellers need to provide detailed information. The government or third-party institutions should let consumers know about the purchased goods as much as possible through awards and qualification recognition to ensure the information symmetry of both parties." He Jiang, director of the Institute of International Business of Guangzhou Academy of Social Sciences, believes that in the development of new formats, there may be some problems such as false propaganda and unreasonable service, and because the regulatory authorities are inexperienced in new formats, and these fields are often complicated in terms of objects and contents, it is more difficult to supervise. "Supervision should run through all aspects of production and consumption. On the one hand, improve quality supervision and strengthen the credit system construction of merchants; On the other hand, it is also necessary to establish a post-consumer evaluation system, record and publish consumer feedback in a timely manner, and enhance the convenience of consumers’ rights protection, so that consumers can buy both. " He Jiang said.

The highlight of NPU(AI chip) and GPU (common chip) is that they can run multiple parallel threads. NPU takes it to another level through some special hardware-level optimizations, such as providing some easily accessible cache systems for some truly different processing cores. These high-capacity cores are simpler than the usual "conventional" processors because they don’t need to perform many types of tasks.

On July 20th, CAMBRIAN was officially listed in A-share science and technology innovation board, becoming the first AI chip, which aroused heated discussion and concern in the industry.

According to relevant data, there are more than 1,500 IC design enterprises in China. However, there are fewer companies with AI chips, and there are only more than 20 companies. Among these AI chip companies, CAMBRIAN is the most prominent, especially the recent IPO, and the stock of Kechuang soared on the first day of listing. So what is AI chip, and how is it different from our ordinary CPU?

From the perspective of principle logic, AI processor is a special chip, which combines artificial intelligence technology and machine learning, making the mobile device of the chip smart enough to imitate the human brain, which is used to optimize the work of deep learning AI, and is also a system using multiple processors with specific functions. The ordinary chip (ordinary cpu) is packaged in a smaller chip package, which is designed to support mobile applications and provide all the system functions needed to support mobile device applications.

Most of the time, the marketing teams of major companies find the word AI (artificial intelligence) very "advanced and gorgeous", so they bind it to almost any possible commercial use. So, you must have heard of it

"Artificial Intelligence Chip" is actually a renamed version of NPU (Neuroprocessing Unit). These are special types of ASIC (Application Specific Integrated Circuits), which are designed to widely apply machine learning in the mobile market.

These ASIC have a special architecture design, which enables them to execute the machine learning model faster, instead of unloading data to the server and waiting for its response. This execution may not be so powerful, but it will be faster because there are fewer obstacles between the data and the processing center.

Generally speaking, we can understand that NPU is AI chip and ordinary chip is CPU.

The CPU will work well in a general load environment, because it has a high IPC, which can be executed through many serial ports. And the CPU follows the Von Neumann architecture, and its core is to store programs and execute them sequentially. The architecture of CPU needs a lot of space to put storage unit (Cache) and Control unit (control unit). Compared with it, the computing unit only occupies a small part, so it is extremely limited in the ability of large-scale parallel computing and is better at logical control.

The highlight of NPU and GPU is that they can run multiple parallel threads. NPU takes it to another level through some special hardware-level optimizations, such as providing some easily accessible cache systems for some truly different processing cores. These high-capacity cores are simpler than the usual "conventional" processors because they don’t need to perform many types of tasks. This whole set of "optimization" makes NPU more efficient, which is why so much research and development will be invested in ASIC.

Machine learning model processing requires CPU, DSP, GPU and NPU to be synchronized at the same time, which is because many chip processing units are working together. But it also explains why such execution is "heavy" for mobile devices.

One of the advantages of NPU is that most of the time is focused on low-precision algorithms, new data flow architecture or memory computing power. Unlike GPUs, they are more concerned with throughput than latency.

Of course, AI algorithm is very important. In image recognition and other fields, CNN convolution network, speech recognition, natural language processing and other fields are commonly used, mainly RNN, which are two different algorithms. However, in essence, they are all multiplication and addition of matrices or vector, and then cooperate with some algorithms such as division and exponent.

In addition, a mature AI algorithm is optimized for specific mathematics of convolution operation and weighted summation. This process is very fast. It is like a GPU without graphics hardware. For the AI chip, if the specific target size is determined, then the total number of multiplication and addition calculations is determined. For example, a trillion times, for example, if I run a program with an AI chip, I can have a meal, and the CPU needs to run for several weeks. No commercial company will waste time.

In addition to the CAMBRIAN, there are also these well-known AI chip companies in China, such as Bitcontinent, Horizon, Tianxin Zhixin, Yizhi Electronics, Exploration Technology, Suiyuan Technology, Hisilicon, Jianan Technology, etc., all of which have experienced the actual landing inspection period from 2015 to the present, before they get to the present situation. The products of each company are also unique, with their own styles in power consumption, performance and application scenarios, which can occupy a place in the vast market of China.

China AI chip company is in a development boom. What about the development of foreign AI chips? Now let’s look at the companies that we think are the top developers of artificial intelligence chips, although there is no specific order-just those companies that have demonstrated their technology and have put it into production or will put it into production soon. The details are as follows:

1. Alphabet (Google’s parent company)

Google’s parent company urges the development of artificial intelligence technology in many fields, including cloud computing, data centers, mobile devices and desktop computers. Perhaps the most noteworthy is its Tensor Processing Unit, which is an ASIC specially designed for Google’s TensorFlow programming framework, mainly used for two branches of AI, machine learning and deep learning.

Google’s Cloud TPU is used in data centers or cloud solutions, and its size is equivalent to a credit card, but the Edge TPU is a coin with a size less than one cent, which is specially designed for some specific devices. Nevertheless, analysts who observe this market more closely say that Google’s Edge TPU is unlikely to appear on the company’s own smartphones and tablets in the short term, and it is more likely to be used in higher-end, enterprise and expensive machines and equipment.

2. Apple

Apple has been developing its own arm chips for many years, and may eventually stop using suppliers such as Intel. Apple has basically got rid of the entanglement with Qualcomm, and it really seems determined to go its own way in the field of artificial intelligence in the future.

The company uses A13 "bionic" chips on the latest iphone and ipad. The chip uses Apple’s neural engine, which is part of the circuit and cannot be used by third-party applications. A13 bionic chip is faster and consumes less power than the previous version. According to reports, A14 version is currently in production and may appear on more mobile devices of the company this year.

3. ARM

The chip design produced by Arm (ArmHoldings) has been adopted by all prominent technology manufacturers including Apple. As a chip designer, it doesn’t make its own chips, which gives it some advantages, just like Microsoft doesn’t make its own computers. In other words, Arm has great influence in the market. The company is currently developing artificial intelligence chip design along three main directions: Project Trillium, an "ultra-efficient" and scalable new processor with the goal of machine learning applications; Machine learning processor, which is self-evident; Arm NN is the abbreviation of neural network, which is a processor for processing TensorFlow, Caffe is a deep learning framework, and there are other structures.

4. Intel

As early as 2016, according to the Wall Street Journal, the chip giant Intel announced the acquisition of the startup NervanaSystems, and Intel will acquire the company’s software, cloud computing services and hardware, so that the products can better adapt to the development of artificial intelligence. But its artificial intelligence chip series is called "neural network processor": artificial neural network imitates the working mode of human brain and learns through experience and examples, which is why you often hear that machines and deep learning systems need "training". With the previous release of Nervana, it seems that Intel will give priority to solving problems related to natural language processes and deep learning.

5. Nvidia (NVIDIA)

In the GPU market, we mentioned that GPU can handle artificial intelligence tasks much faster than CPU, and Nvidia seems to be in a prominent position. Similarly, the company seems to have gained an advantage in the nascent artificial intelligence chip market. These two technologies seem to be closely related, and NVIDIA’s progress in GPU will help accelerate the development of its artificial intelligence chip. In fact, gpu seems to be the support of Nvidia artificial intelligence products, and its chipset can be called artificial intelligence accelerator. Jetson Xavier was released in 2018, and Huang Renxun, CEO of Jetson Xavier, said at a news conference: "This small computer will become the brain of future robots".

Deep learning seems to be NVIDIA’s main interest. Deep learning is a higher level of machine learning. You can think of machine learning as short-term learning with relatively limited data sets, while deep learning uses a large amount of data collected over a long period of time to return results, which in turn are designed to solve deeper and potential problems.

6. AMD (Ultramicro Semiconductor)

Like NVIDIA, AMD is another chip manufacturer closely related to graphics cards and GPUs, partly due to the growth of the computer game market in the past few decades and the growth of the bitcoin mining industry. AMD provides hardware and software solutions, such as machine learning and deep learning of EPYC cpu and Radeon Instinct gpu. Epyc is the processor name provided by AMD for servers (mainly used in data centers), while Radeon is a graphics processor mainly for gamers. Other chips provided by AMD include Ryzen, and perhaps the more famous Athlon. It seems that the company is still in a relatively early stage in the development of artificial intelligence-specific chips, but in view of its relative strength in the GPU field, observers believe that it will become one of the leaders in this market. AMD has signed a contract to provide Epyc and Radeon systems to the U.S. Department of Energy to build one of the fastest and most powerful supercomputers in the world, which is called "Frontier".

7. Qualcomm (Qualcomm)

Qualcomm made a lot of money from the cooperation with Apple at the beginning of the smartphone craze, and Qualcomm may feel left out in the cold about Apple’s decision to stop buying its chips. Of course, Qualcomm itself is not a small company in this field, and considering the future, it has been making some major investments.

Last year, Qualcomm released a new "cloud artificial intelligence chip", which seems to be related to its development in the fifth generation telecommunications network (5G). These two technologies are considered to be the basis for building a new ecosystem of self-driving cars and mobile computing devices. Analysts said that Qualcomm is a latecomer in the field of artificial intelligence chips, but the company has rich experience in the mobile device market, which will help realize its goal of "making artificial intelligence on devices everywhere".

Of course, other large international companies, such as Samsung, TSMC, Facebook, IBM and LG, are also developing their own AI chips. Whoever can master the cutting-edge AI chips first will get a slice of the new economic rising trend.

The reality described by the marketing departments of major companies is completely different from the reality outside those companies. Although decades of research have given us new ways to process information and classify input, which is faster than ever, there is no real AI in the hardware we buy, so which chip company can seize the market pain point and realize the application first, it can gain a great advantage on the track of artificial intelligence chips.

At present, the global artificial intelligence industry is still in a high-speed development, and the distribution of different industries provides a broad market prospect for the application of artificial intelligence. The commercialized society needs the application of artificial intelligence. AI chip is the hardware foundation for realizing the algorithm, and it is also the strategic commanding height of the future artificial intelligence era, and all the top companies in the world will fight for it. However, because the current AI algorithms often have their own advantages and disadvantages, only by setting a suitable scene for them can they best play their role. I also hope that AI can enter the sight of ordinary people this morning.

From the perspective of industrial development, it is still in the primary stage of artificial intelligence chips, and there is extraordinary room for innovation in both scientific research and commercial applications. In the application scenario, the AI chip with iterative algorithm develops into a general intelligent chip with higher flexibility and adaptability, which is the inevitable direction of technology development. Less computing bit width of neural network parameters, more customized design of distributed memory, more sparse large-scale vector realization, higher computing efficiency, smaller volume and higher energy efficiency in complex heterogeneous environment, the integration of computing and storage will become the main characteristics and development trend of artificial intelligence chips in the future.

　　Who should the copyright of the picture "work" generated by artificial intelligence belong to? With the rapid development of generative artificial intelligence technology, users only need to input some prompt words, and the AI model can produce corresponding words, pictures, codes and other content. So, is the content generated by AI protected by copyright law? How to define and divide the ownership of corresponding rights? Can people freely use the content generated by AI on the network? These copyright issues involving artificial intelligence urgently need a "statement" from the law. At the end of 2023, the Beijing Internet Court concluded the dispute over the right of signature and information network communication between Li and Liu’s works, made clear for the first time the attribute of using artificial intelligence to generate a picture "work", and put forward the view that whether the content generated by artificial intelligence constitutes a work needs to be judged on a case-by-case basis. The judgment of this case has made a pioneering exploration on the legal issues related to the products of artificial intelligence.

　　Pictures generated by artificial intelligence are used by others.

　　In August 2023, the plaintiff Li sued the court, claiming that on February 24, 2023, he used the open source software Stable Diffusion to generate a picture involved in the case by inputting hints, and published the picture on the platform of Little Red Book. After the plaintiff found that the defendant Liu used the pictures involved in an article in Baijiahao. The defendant not only did not get his own permission, but also cut off the signature watermark, which made the relevant users mistakenly think that the defendant was the author of the work, seriously infringing on his right of signature and information network dissemination. Therefore, the court is requested to order the defendant to publicly apologize at Baijia, eliminate the influence and compensate the economic loss of 5,000 yuan.

　　The defendant argued that the specific source of the pictures involved could not be provided, nor could the watermark of the pictures involved be explained, and it was uncertain whether the plaintiff enjoyed the rights of the pictures involved. The main content of the article published by the defendant is original poetry, not the pictures involved, and it has no commercial use and no intention of infringement.

　　The court found through trial that the process of generating the pictures involved was that the plaintiff downloaded the Stable Diffusion model, and then entered dozens of prompt words in the forward prompt words and the reverse prompt words respectively, and set the iteration steps, picture height, guide coefficient of prompt words and random seeds to generate the first picture; Under the condition that the above parameters are unchanged, the weight of one model is modified to generate a second picture; Under the condition that the above parameters are unchanged, the random seed is modified to generate a third picture; Under the condition that the above parameters remain unchanged, the content of positive prompt words is added to generate the fourth picture (that is, the picture involved).

　　Does the picture generated by artificial intelligence constitute a work?

　　According to the defense opinions of the defendant and the defendant and the facts ascertained, the Beijing Internet Court holds that the focus of the dispute and the difficulties in the trial are as follows: First, whether the pictures generated by artificial intelligence involved in the case constitute a work and what kind of work it constitutes; Second, whether the plaintiff enjoys the copyright of the pictures involved; Third, whether the accused behavior constitutes infringement and whether the defendant should bear legal responsibility.

　　First of all, from the appearance of the pictures involved, it is no different from the photos and paintings that people usually see. It obviously belongs to the art field and has certain forms of expression. The pictures involved were generated by the plaintiff using the generative artificial intelligence technology. From the time the plaintiff conceived the pictures involved to the time the pictures involved were finally selected, the plaintiff made some intellectual investments, such as designing the presentation mode of the characters, choosing the prompt words, arranging the order of the prompt words, setting relevant parameters, and choosing which picture meets the expectations. The pictures involved reflect the intellectual input of the plaintiff, so the pictures involved have the elements of "intellectual achievements".

　　Judging from the pictures involved, there are identifiable differences with previous works. Judging from the generation process of the pictures involved, the plaintiff designed the picture elements such as characters and their presentation methods through hints, and set the picture layout and composition through parameters, which reflected the plaintiff’s choice and arrangement. In addition, after the plaintiff obtained the first picture by inputting prompt words and setting relevant parameters, he continued to add prompt words and modify parameters, and constantly adjusted and corrected the picture involved. This adjustment and correction process reflected the plaintiff’s aesthetic choice and personality judgment. In the absence of evidence to the contrary, it can be concluded that the pictures involved were independently completed by the plaintiff, which reflects the plaintiff’s personalized expression, so the pictures involved have the elements of "originality".

　　The pictures involved are graphic plastic art works with aesthetic significance composed of lines and colors, which belong to art works and should be protected by copyright law.

　　Second, the plaintiff is the author of the pictures involved and enjoys the copyright of the pictures involved. As far as the ownership of the works involved is concerned, China’s copyright law stipulates that the author is limited to natural persons, legal persons or unincorporated organizations, so the artificial intelligence model itself cannot be the author stipulated by China’s copyright law. The plaintiff sets up the artificial intelligence model involved in the case according to the need, and finally selects the person involved in the case. The picture involved is directly generated based on the plaintiff’s intellectual input and reflects the plaintiff’s personalized expression, so the plaintiff is the author of the picture involved and enjoys the copyright of the picture involved.

　　Third, the defendant has infringed the rights enjoyed by the plaintiff and should bear the tort liability. In this case, the defendant, without permission, used the pictures involved in the case as illustrations and posted them in his Baijia account, so that the public could obtain the pictures involved in the case at the time and place selected by him, infringing on the plaintiff’s right to spread information on the network. In addition, the defendant removed the signature watermark from the pictures involved, which infringed the plaintiff’s signature right and should bear the tort liability.

　　To sum up, the Beijing Internet Court ruled in the first instance that the defendant apologized and compensated the plaintiff 500 yuan. In this regard, neither party has appealed, and the judgment has now taken effect.

　　■ referee analysis

　　Whether the content generated by artificial intelligence constitutes a work needs to be judged individually.

　　Beijing Internet Court Zhuge

　　In recent years, the academic discussion on the copyright of AI-generated content has never stopped, which provides a reference for the referee in this case.

　　In this case, the pictures involved were generated by the plaintiff using AI, and judged according to the constitutive requirements of the works in the copyright law. Because the pictures involved reflected the plaintiff’s original intellectual input, they were recognized as works, and the relevant copyrights belonged to the plaintiff. At the same time, the judgment of this case emphasizes that whether the content generated by artificial intelligence constitutes a work requires case-by-case judgment and cannot be generalized. The verdict of this case fully absorbed the academic discussion, which reflected "one inheritance" and "two considerations".

　　"One inheritance", that is, the judgment of this case, is the inheritance and development of the previous "Film Law Firm v. Baidu Copyright Case" in Beijing Internet Court. This case continues to adhere to the view that the copyright law only protects the creation of natural persons, while the artificial intelligence model does not have free will, is not the subject of law, and cannot be the "author" in China’s copyright law; This case continues to hold that under normal circumstances, the right to generate pictures by using AI belongs to the person who uses artificial intelligence software; In addition, the case continues to emphasize that according to the principle of good faith and the need to protect the public’s right to know, relevant subjects should clearly mark the artificial intelligence technology or model they use. Different from the previous case, except the artificial intelligence model involved in the case is more intelligent, the plaintiff in this case has more intellectual input, so it has the basis for further exploring the application of copyright law to protect it.

　　During the trial of the case, we repeatedly conducted "two considerations":

　　First, when the traditional theory encounters a brand-new application scenario, whether it should be adjusted and developed. We believe that only by adhering to the future-oriented judicial concept can we better encourage the application of new technologies and promote the development of new formats. The original copyright theory and practice presupposed art works as the main creative way, which was determined by the technical level of creative tools at that time. Since entering the era of artificial intelligence, human creative tools have undergone fundamental changes. People no longer need to draw lines and fill colors, but use AI to create, but this does not mean that human beings do not need to choose and arrange picture elements. By designing hints, different people will produce different results, which can reflect the original intellectual input of human beings. In this brand-new technical background, the traditional copyright theory and the reality of technical development have not matched, so it should be adjusted and developed to better meet the needs of rights protection and industrial development. Therefore, we can’t stick to the historical standards. Only by thinking about the future can we choose the path of the present.

　　Second, whether the identification of works is only based on legal judgment is also a question of value judgment. "Originality", as a rule to define the core elements of a work, is gradually established by the courts of various countries through the trial of individual cases. In this process, there are arguments in the theoretical circle and reference from judicial practice, and more importantly, it is based on the balance of interests, and comprehensively considers the types of works, creative space, industrial policies, public demand and other factors in the field, trying to make the best explanation. At the moment when China’s artificial intelligence industry is developing rapidly, how to serve and ensure the healthy and efficient development of the industry based on China’s specific reality and China’s value consensus is the question of the times that we must answer. In this context, based on the value measurement of the country, society, citizens and other dimensions, we believe that by recognizing the "work" attribute of pictures generated by artificial intelligence and the user’s "creator" identity, it is more conducive to encouraging users to use AI tools to create enthusiasm, thus realizing the inherent goal of "encouraging works to create" in the copyright law, promoting relevant subjects to identify the content generated by AI, thus promoting the implementation of regulatory laws and regulations, and protecting the public’s right to know, and strengthening people’s awareness.

　　■ Views of all parties

　　It is confirmed for the first time that AI generates the attribute of "Art Works"

Cui Guobin, Professor of Tsinghua University Law School

　　The judgment of this case has made a meaningful exploration of many copyright problems caused by generative AI, and put forward reasonable solutions. This is innovative on a global scale and has important reference value for future judicial practice and academic research.

　　First of all, the court confirmed the "art work" attribute of AI products. The court held that users use generative AI to output pictures, even if AI users do not directly draw lines and colors, they may still constitute intellectual achievements in the sense of copyright law and fall into the category of "works of art", regardless of the necessity of "other works". When the legislator did not create a new category for such works, the court included it in the scope of "art works", which was in line with public expectations.

　　Secondly, the court clearly judges whether the user has made an original contribution. The court stressed that "whether the use of artificial intelligence to generate pictures reflects the author’s personalized expression requires case judgment and cannot be generalized." "After the plaintiff obtained the first picture by inputting prompt words and setting relevant parameters, he continued to add prompt words, modify parameters, and constantly adjusted and corrected, and finally obtained the picture involved. This adjustment and correction process also reflected the plaintiff’s aesthetic choice and personality judgment." In this case, whether the user’s actual creative behavior leads to the AI ? ? output fully reflecting its personality is a matter of fact, and there is room for debate. However, the court’s thinking of analyzing legal issues is completely in line with the underlying logic of copyright law and public policy, leaving more flexible space for the development of new technologies. After selecting the first draft of the picture output by AI, users have a relatively specific idea of the work, and then modify it repeatedly on this basis. In theory, as long as there are enough rounds or details, users do have the possibility of making specific original contributions.

　　Under the background of the increasing integration of painting programming tools (such as Photoshop) and generative AI system, copyright law should encourage the public to use new creative tools to create more and better works of art, instead of discriminating against users of such tools, easily denying users’ original contributions and forcing users to stay away from such powerful creative tools. Therefore, I agree with the court’s judgment that "it is more conducive to the creation of works and the development of artificial intelligence technology to encourage more people to create with the latest tools by appropriate legal means", which is far more forward-looking than the general objection of denying the original contribution of users.

　　In addition, this judgment also deeply discusses the attribution of AI-assisted creative works. The court emphasized that the designer of AI system is only the producer of creative tools, and "there is neither the will to create the pictures involved nor the pre-set subsequent generation content". At the same time, the designer of the artificial intelligence model involved in the case gives up the right to claim the output content in the license provided by him. Therefore, the developer of AI system is not the author of the dispute picture. In the court’s view, "the plaintiff directly sets the artificial intelligence model involved in the case according to the needs, and finally selects the picture involved. The picture involved is directly generated based on the plaintiff’s intellectual input and reflects the plaintiff’s personalized expression, so the plaintiff is the author of the picture involved." This idea is worthy of recognition.

　　Finally, it is worth mentioning that the court’s application of the minimum amount of statutory compensation (500 yuan) should also be a balanced choice reflecting the judicial policy. Many people are worried that copyright law will protect the works created by users using AI, which will lead to the proliferation of infringement lawsuits related to AI works and harm the public interests of society. In order to avoid this negative consequence, the court should consider the particularity of AI creation when determining the standard of damages, and avoid over-compensation to users, thus stimulating too many lawsuits. In this case, it is a reasonable choice to choose the lower limit of legal compensation "according to the pictures involved and the circumstances of infringement use", which reflects this important judicial policy. Of course, this does not rule out that in future cases, users will use AI to create high-value works and get higher damages.

　　Very valuable pioneering exploration

Shen Fen, a big model manufacturer.

　　Through this case, Beijing Internet Court made a very valuable and pioneering exploration on the legal issues related to artificial intelligence products.

　　In the concept of recognition, it is confirmed that users can obtain the copyright of artificial intelligence products. In this case, the court found that natural persons can obtain the copyright of products by making substantial contributions in the process of using generative artificial intelligence. This has a positive effect on encouraging users to actively use artificial intelligence to create high-quality works.

　　Protecting the works that users have made substantial contributions in the process of product production plays an important and positive role in the use and promotion of generative artificial intelligence. In the process of ownership determination, it is equally important to consider and respect the contracts between the designers, providers and users of artificial intelligence models and services to help the market-oriented development of artificial intelligence industry and support the formation of various business models. It is of great significance for the development of China’s artificial intelligence industry and the improvement of the quality of cultural and artistic works to give reasonable protection to high-quality works created by generative artificial intelligence and help users, artificial intelligence developers and operators to realize closed-loop business.

The Ministry of Education held a press conference to introduce the fourth China "internet plus" College Students Innovation and Entrepreneurship Competition. (China Education News reporter Zhang Jinsong/photo)

　　Xinhuanet Xiamen, March 29th, "Brave the tide of the times, dare to break new ground, take root in the land of China and write the chapter of life", and the 4th China "internet plus" College Students Innovation and Entrepreneurship Competition was launched in Xiamen. On March 29th, the Ministry of Education held a press conference in Xiamen University, Fujian. Wu Yan, Director of the Higher Education Department of the Ministry of Education, made a press release on the overall situation of the contest. Zhang Rong, president of Xiamen University, and Xue Weimin, deputy director of Fujian Provincial Department of Education, introduced the preparations for the contest. Zhang Wang, a representative of the student team, introduced her participation in the "Youth Red Dream Tour".

　　Wu Yan introduced that the theme of this year’s contest is "Brave the tide of the times, dare to break through and create, and take root in China to write the chapter of life". The main tone of the contest is "breadth, height, depth and temperature". This year’s competition will expand the scale of participation, achieve full coverage of regions, schools and student types, and greatly expand the international track; Fully implement the "Youth Red Dream Tour" to cultivate youthful strength with ideals, skills and responsibilities; National strategies such as strengthening the new force of innovation and entrepreneurship, service innovation-driven development, "Belt and Road" construction, rural revitalization and poverty alleviation.

　　Frequent highlights to create a platform for global dual-innovation communication

　　Wu Yan introduced that there are three main highlights in this competition.

　　The first is to build a platform for global dual-innovation communication. Expand the international track of the competition, attract outstanding college students’ innovative and entrepreneurial teams from all over the world to participate in the competition, and enhance the global influence of the competition. The contest plans to establish the "21st Century Maritime Silk Road" innovation and entrepreneurship education community, deepen the cooperation and youth exchanges of countries along the "Belt and Road", and contribute new experiences to the development of international higher education.

　　The second is to give a good ideological and political course in the country’s largest colleges and universities. The contest will carry out the "Youth Red Dream Tour" on a larger scale, at a higher level and at a deeper level, promote the integration of innovation and entrepreneurship education with ideological and political education, and combine innovation and entrepreneurship practice with rural revitalization strategy and accurate poverty alleviation to create the largest ideological and political course in China. Organize college students from science and engineering, agriculture and forestry, medicine, teachers’ colleges, law, humanities and social sciences, entrepreneurs, investors, etc. to enter the old revolutionary areas and poor areas, accept ideological baptism, learn revolutionary spirit, inherit red genes, radiate the intelligence, technology and project resources of colleges and universities to the vast rural areas, promote local social and economic construction, and help precision poverty alleviation and rural revitalization.

　　The third is to make a good educational film. Put the vivid stories of college students’ innovation and entrepreneurship on the big screen, show the spirit of creativity, struggle, unity and dream, make a classic film reflecting education, pay tribute to the 40th anniversary of reform and opening up, and present gifts to the new era. At present, the film preparation work is in full swing, and the film premiere is planned for December.

　　In addition, Fujian Province is the starting point of "21st Century Maritime Silk Road", which has geographical advantages such as the west coast of the Taiwan Strait. This year’s competition will highlight the characteristics of "Haisi" and strengthen the cooperation of innovation and entrepreneurship education in countries along the Maritime Silk Road; Highlight the characteristics of the Taiwan Strait and promote in-depth exchanges between young college students on both sides of the Taiwan Strait; Highlight the characteristics of marine culture, and cultivate students’ innovative and entrepreneurial spirit of daring to innovate, take risks and be the first in the world. Taking the 40th anniversary of the reform and opening up as an opportunity, the contest will achieve greater and higher-level open cooperation, build an international contest platform, and strive to hold an amazing and extraordinary global double-creation event.

　　One main event and five concurrent activities.

　　This year’s contest plans to hold a series of "1+5" activities.

　　"1" is the main event, and the national finals will be held on the basis of school competitions and provincial competitions. The live competition in the finals includes the gold medal competition, the semi-final competition and the championship competition. March-May is the registration stage, the preliminaries and semi-finals will be arranged from June to September, and the national finals will be held in the middle and late October.

　　"5" is five activities in the same period, including: First, the "Youth Red Dream Tour" was held. The second is to hold a series of activities on the 21st Century Maritime Silk Road. Establish the 21st Century Maritime Silk Road University Alliance and hold the Belt and Road University Presidents’ Innovation and Entrepreneurship Education Forum to promote extensive and pragmatic educational cooperation and exchanges among universities in countries and regions along the Belt and Road. The third is to hold the "College Student Maker Show".

The fourth is to hold a dialogue between outstanding entrepreneurs and college entrepreneurs in the 40 years of reform and opening up. Invite influential entrepreneurs, investors, industry leaders and technical experts who have emerged in the past 40 years of reform and opening up to talk with college entrepreneurs, share successful experiences and help college students grow and develop. The fifth is to hold a docking tour of outstanding projects in the competition. In 2018, during the "Digital China" Construction Summit, the 22nd China International Fair for Investment and Trade and the finals of the competition, special zones will be set up to carry out excellent project exhibition and exchange, investment and financing negotiation and docking activities, and further promote the transformation and application of the results of the competition. Implement the landing plan of international outstanding innovation and entrepreneurship projects, hold a joint exhibition between local governments and dual-innovation projects, and promote high-quality projects with high technology content, great market potential, good social benefits and obvious investment value to settle in China.

　　Compared with previous events, this year’s competition has also added three new contents. First, the "Youth Red Dream Tour" track has been added. The events participating in this track must be the events participating in the "Youth Red Dream Tour"; Projects participating in the "Youth Red Dream Tour" can choose to participate in the main track or the "Youth Red Dream Tour" track competition (but only one track can be selected). The second is to add awards. The number of events that entered the national finals on the main track increased from 120 to 150, and the number of gold medals increased from 30 to 50, and the number of silver medals increased from 90 to 100. The newly-added "Youth Red Dream Tour" track has 10 gold prizes, 30 silver prizes, 160 bronze prizes, 20 collective prizes in colleges and universities, 8 provincial and municipal outstanding organization prizes and several individual prizes. In addition, international track awards and Hong Kong, Macao and Taiwan project awards have also increased. The third is to set up a "Discipline and Supervision Committee" to supervise the organization and evaluation of the competition and the relevant work of the co-organizers, create a good atmosphere, and ensure that the competition is fair, just and open.

　　It is reported that since its establishment in 2015, the China "internet plus" University Student Innovation and Entrepreneurship Competition has accumulated 2.25 million university students and 550,000 teams to participate, and a large number of high-quality projects with high technology content, great market potential and good social benefits have emerged, showing the energetic and uplifting style of contemporary young university students. It has become the largest and most influential university student innovation and entrepreneurship event in China, and has also begun to become a beautiful landscape of international higher education.

Since its debut, the discussion about Song PLUS DM-i has been endless: the first SUV model equipped with DM-i super hybrid system, and the "dragon beard shape" with the same origin as Han …… With its official listing, its attention has soared again and again, so can Song PLUS DM-i meet the expectations of consumers? Today, let’s have a try.

Wide body and low body lead the trend, and the exclusive design of new energy is well received.

Evaluating an SUV model, high value is definitely a plus item. Song PLUS DM-i extended the design language of Dragon Face 3.0, and the front face design of "Eight-faced Dragons" matched with the rhythmic front grille of lattice scales, which was exquisite and domineering, highlighting the exclusive design of new energy vehicles; The LED light group has been upgraded, the fog light area has a sharp edge shape, and the turn signal is also integrated into the headlights; The wide-body and low-lying styling design and the long wheelbase of 2765mm not only make it the most fashionable SUV in the market, but also the largest SUV in its class. The overall design is closer to the current hot-selling BYD Han DM, which has attracted a crowd before departure.

Entering the car, Song PLUS DM-i adopts the exclusive color scheme of Eclipse Blue+Sky Grey, where blue stands for "technology" and "quietness", and grey highlights "sense of space" and "lightweight". The fresh and elegant color scheme makes people fondle it and feel better. The multi-layer floating design makes the space more natural and clear.

In addition, the Song PLUS DM-i is equipped at the beginning. The whole system comes standard with 12.8-inch 8-core adaptive rotating suspension Pad, mobile phone NFC car key, Dirac 9 speaker intelligent music cockpit, OTA remote upgrade, 360 panoramic image of megapixels, 6 airbags in front and rear rows, VTOL 220V power output and other functions. The high-equipped model of this test drive is also equipped with seat ventilation and heating function. The friends who test drive together sighed, "You can’t go back after using it."

Generally speaking, Song PLUS DM-i not only inherits the outstanding quality of the fuel version, but also creates an exclusive aesthetic feeling of science and technology. It is fashionable in modeling, large in space, cool in sitting and high in configuration, which makes people unforgettable.

Super hybrid strong blessing, the whole test drive "calls" more than

This test drive is the top version of Song PLUS DM-i with a pure battery life of 110KM. It is equipped with three core technologies: Xiaoyun-plug-in special 1.5L high-efficiency engine, EHS electric hybrid system and DM-i super hybrid special power blade battery. The comprehensive power is 173kW, and the whole test process is full of surprises. The multiple advantages of "fast, smooth, static, stable and accurate" are deeply rooted in people’s hearts!

When driving in urban areas, you can feel that the power output of the Song PLUS DM-i is linear and direct, and the throttle response is crisp and neat. When the traffic jam starts, there is no delay, and the power response is comparable to that of pure electric vehicles. When trying to overtake and merge, you can feel generate with a steady stream of power by kicking down. Even high-speed overtaking is fast and steady, so you don’t have to worry about overtaking failure due to lack of power. The accelerated test has answered the doubts, and the actual measurement has reached 7.9s, which is 2-3s faster than that of the same class fuel vehicle. The power experience is completely the level of a 2.0T high-power engine, which is very popular!

During the test drive, thanks to the well-regulated EHS electric hybrid system, the Song PLUS DM-i is super smooth to drive, and there is no sense of frustration in the shift of traditional fuel vehicles at all. The whole vehicle gives people a sense of calmness, and it drives like a pure electric vehicle, which is popular with people!

It is worth mentioning that even if you gallop on the highway with a speed of 100km/h, the noise transmitted into the car is very small, and the communication between the front and rear rows is very smooth, so there is no need to "pull your voice" at all. Song PLUS DM-i adopts double-layer sound insulation and heat insulation glass in the front row and front windshield. Through the acoustic package and seal design of the whole vehicle, it has achieved a high NVH level, which gives people the impression that it is equivalent to bringing its own "noise-reducing headphones" and is quiet in people’s hearts!

With multiple adjustments, the Song PLUS DM-i turns accurately and enjoys stable driving.

Previously, on the high speed, the Song PLUS DM-i felt like a medium-sized SUV, and the chassis had a calm performance. On the way to the test drive, we mistakenly entered a bumpy road, which made us experience the solid chassis adjustment of the Song PLUS DM-i in all directions. Song PLUS DM-i, which was personally operated by German chassis master Hans Kirk, was driving on the potholed road, and the shock was filtered very simply, with almost no unnecessary beating, and the overall performance was still firmly in the hearts of the people!

It is worth mentioning that Song PLUS DM-i has a profound knowledge in handling. The elk test passed the speed of ≥76km/h, and the whole vehicle not only has a small roll, but also has a sensitive and linear brake. In some U-turn sections, the minimum turning radius of 5.55 meters at the same level brings the pleasure of "passing through" and is popular!

In addition, after a long period of congestion, the fuel consumption of Song PLUS DM-i is only 4.6L/100km.

, super mixing is more and more blocked!

It is no exaggeration to say that after five minutes of test drive, you can experience the five extrasensory performances of Song PLUS DM-i, which are fast, smooth, quiet, stable and accurate. In addition, all departments of Song PLUS DM-i can enjoy the preferential policies of exemption from purchase tax and unlimited access to green cards, and have introduced the three-electric lifetime warranty for non-operating vehicles (the first owner) and the six-year or 150,000-kilometer vehicle warranty, which eliminates the worries of car use and further stimulates multiple advantages. In the future, what wonderful story will Song PLUS DM-i write about "the world’s first wide-body super hybrid SUV"? Let’s pay attention together.

Fast Technology reported on May 14th that Gary Black, a well-known Tesla investor and future fund management partner, released the data released by YipitDate, a credit card data provider.

The data shows that,Although Tesla American car owners experienced the FSD service for free during the trial period, only 2% car owners chose to continue to subscribe after the trial period ended, far below Blake’s expectation of 6%.

Blake also reminded that because the sample size is only 3,500, it may not fully reflect the wishes of Tesla owners. It is suggested that Tesla deeply analyze the reasons for the low acceptance rate, whether it is related to the added value of services or the pricing of 99 US dollars/month.

It is understood that Tesla’s self-driving products are divided into three levels:Basic AP(Autopilot), enhanced assisted driving EAP(Enhanced Autopilot), and the highest level FSD.

At present, AP is provided free of charge in China, and EAP costs RMB 32,000.The price of FSD in North America is $15,000 or $199 per month, and its functions include navigation-assisted driving, automatic lane change and automatic parking.

Since the FSD v12 version, Tesla has introduced the "end-to-end neural network", which controls cars by neural networks instead of traditional programming codes, and is praised by Musk as an innovation of "changing the rules of the game".

He predicted that,FSD will be updated every two weeks, and 26 version iterations will be realized every year, bringing 78 major improvements, which indicates a significant improvement in the security and functionality of FSD.

On January 26th, Shandong Provincial Department of Transportation held a press conference of Spring Festival travel rush in 2024 to introduce the situation and work arrangement of Spring Festival travel rush in 2024 in Shandong Province.

Spring Festival travel rush officially starts today and ends on March 5th, 15 days before the festival and 25 days after the festival, totaling 40 days. This year’s Spring Festival is the first Spring Festival after the epidemic has turned smoothly. The Spring Festival holiday has been increased from 7 days to 8 days. At the same time, the state also encourages all units to arrange employees to take a break on New Year’s Eve, which can add up to a long holiday of 9 days. Policies to promote the consumption of cultural tourism are being introduced all over the country, and our province will also launch a series of activities such as "friendly shandong New Year’s Celebration". The cultural tourism market is heating up, the masses have a strong desire to travel, and the flow of family visits and tourism will increase substantially. It is expected that the cross-regional personnel flow will reach a record high The Ministry of Transport has made it clear that expressways will be free for 9 days during the Spring Festival holiday. It is estimated that the traffic volume of self-driving passenger cars on expressways in Spring Festival travel rush will exceed 60 million, reaching a record high. The traffic volume of expressways will run at a high level, and the traffic pressure will increase compared with previous years. In terms of passenger flow of traditional commercial transportation, it will reach about 48 million passengers, and it will also be restored to the level before the epidemic, so sufficient transportation capacity has been prepared. However, high-speed rail and civil aviation may still have short-term shortage of transportation capacity in hot routes and hot areas during peak hours. During the period of Spring Festival travel rush, the passenger and cargo flow increased, and the bad weather was prone to occur, so Spring Festival travel rush Baotong was under certain pressure to ensure smooth supply and safe travel.

The 40-day period in Spring Festival travel rush is the period of the largest personnel flow and the most concentrated travel, which is related to the vital interests of the people. The CPC Central Committee, the State Council, the provincial party committee and the provincial government attach great importance to Spring Festival travel rush’s work, and demand that the transportation service guarantee and production safety be well coordinated to ensure the safety, order and warmth of Spring Festival travel rush. In order to do a good job in organizing and guaranteeing the work in Spring Festival travel rush this year, the provincial government established the working mechanism of Spring Festival travel rush in Shandong Province in 2024 to coordinate and organize the work in Spring Festival travel rush. The Provincial Department of Transportation took the lead in formulating the "Work Organization Guarantee Scheme for Spring Festival travel rush in the Province" and supporting measures. On January 24th, the provincial government held a special meeting to emphasize Spring Festival travel rush and the work of safety in production.

Wang Guangpeng, director of the Transportation Management Department of Shandong Provincial Department of Transportation, said that the Provincial Department of Transportation will strengthen coordination and linkage with all members of Spring Festival travel rush’s working mechanism, adhere to the people first and life first, and strive to create a "safe Spring Festival travel rush, convenient Spring Festival travel rush and warm Spring Festival travel rush" to ensure the safe, convenient and comfortable travel of the broad masses of people and ensure the smooth and orderly operation of key production and living materials.

First, strengthen the optimization of transportation organization.In view of the booming tourism market this year, the transportation capacity of key tourist areas and scenic spots will be increased, and transport enterprises will be guided to operate special tourist lines, through trains and customized passenger transport to meet the travel needs of tourists through multiple channels. High-speed rail and civil aviation will also "run at full speed" to encrypt the number of flights and flights. In addition, rural areas are also places where travelers gather during the Spring Festival, and we will also urge the rural passenger transport capacity to be put into operation.The second is to strengthen the self-driving service guarantee.In view of the strong demand for self-driving travel in Spring Festival travel rush, the Provincial Department of Transportation organized the theme activity of "Warm Way Home" in the expressway service area throughout the province, with the theme of "Happy Service Area Tesco New Year Festival" to create a festive atmosphere, improve service quality and display a civilized image. At the same time, through the highway variable information board, traffic broadcast, WeChat, Weibo and other means, the road conditions and various service information will be updated in time to provide "accompanying" services for the public.The third is to do a good job in travel services for key groups.In-depth development of Spring Festival travel rush’s "full love journey" activities, implementation of Spring Festival travel rush’s voluntary service "Warm Winter Action", organization of volunteers focusing on guidance and consultation, ticketing assistance, civilized travel and the elderly, the disabled, minors and other groups to provide accurate and professional services. For migrant workers returning to their hometowns and returning to work, students will be instructed to carry out "point-to-point" transportation services in a timely manner according to their needs. At the same time, we will fully implement the travel priority policies for military personnel, firefighters and rescuers, and open up a "green channel."The fourth is to improve the transportation connection.Reasonable arrangement of bus and tram, urban rail transit, taxis and other transport capacity and bus stations, railway stations, airports, docks and other transport hubs, to ensure the connection of passengers such as passenger trains, night arrival flights and passenger ships.

Do a good job in safety production in Spring Festival travel rush.Resolutely carry out safety production throughout the whole process and every link of Spring Festival travel rush’s work, so as to ensure people’s safe and healthy travel.First, strengthen the implementation of the Spring Festival travel rush safety responsibility system.In accordance with the requirements of "three management and three musts", strengthen the leadership of local governments, compact the regulatory responsibilities of departments and the main responsibilities of enterprises, pay close attention to the implementation of various preventive measures for production safety in Spring Festival travel rush, strengthen safety training and warning education for all employees, and resolutely build a security line.The second is to strengthen the whole process of investigation and inspection.Thoroughly carry out a thorough investigation of hidden dangers, effectively solve the hidden dangers that affect Spring Festival travel rush’s security before Spring Festival travel rush, and resolutely put an end to the "sick" operation of means of transport and facilities. For 40 days, Spring Festival travel rush continuously carried out investigation and rectification of potential risks and self-examination and spot checks to ensure the safety and order of all links in Spring Festival travel rush.The third is to strengthen the supervision of key areas.The key areas and parts of Spring Festival travel rush will be included in the scope of key control, and measures such as notification, interview, administrative punishment and credit punishment will be fully utilized to implement the whole process of production safety supervision.The fourth is to improve the safety emergency response capability.Strengthen the monitoring of severe weather and establish a mechanism for rapid meteorological notification and linkage response.

Strictly implement the free passage policy and the "green passage" policy for small passenger cars on major holidays to avoid long-term and long-distance queuing congestion. Here, I also remind the car owners and friends that the free passage time of the expressway is based on the time when the vehicle leaves the exit toll lane. There is no need to stay at the entrance and wait for the free time to start. If the free time is coming to an end, you can drive out of the expressway nearby and then drive into the expressway to reach your destination. You only need to pay the remaining travel expenses.The third is to ensure the transportation of key materials.We will spare no effort to ensure the efficient operation of trunk transportation, collection and distribution of key materials such as energy, grain, foreign trade and agricultural materials, and do a good job in giving priority and convenient access to transportation vehicles for daily necessities such as vegetables, fruits, meat and poultry, eggs and milk, and guide and support logistics and express delivery enterprises to maintain normal operation during their stay in Spring Festival travel rush to meet the basic delivery service requirements during the Spring Festival.

1905 movie network news A few days ago, the fantasy adventure animated film exposed a feature film, in which the protagonist Muzili and his family were having a family "night chat", and then Muzili went to its "secret passage" … … As the first animated co-production in China and New Zealand, The Legend of the Erect Elephant has cross-cultural characteristics and milestone significance. The film focuses on family affection and fantasy adventure, bringing a vivid growth education lesson for adults and children, and it is the best choice to accompany children into the cinema in summer.

Animation restores the true feelings of life and pokes parents’ tears

The movie The Legend of the Erect Elephant tells that the Peach Chestnut Elephant is a higher creature with hands and feet, knows how to think, and has the same language ability as human beings, but it can’t get rid of the fate of being enslaved because of being cursed. However, by chance, the hero Muzili and his son Le Er went to an ancient cave full of mystery, and discovered the secret of the "Peach and Chestnut Elephant" family, and finally rose up and rebelled, bringing the family a story of freedom and liberation.

In the feature footage of this exposure, Muzili dragged herself back home and discussed the upcoming baby with his wife Bai Na. Muzili’s premonition of the child’s sex was frequently vomited by Bai Na, and the way they bickered was very funny. At this time, Le Er is playing with its chicks, so naughty that Muzili can’t help but sigh that one boy is enough. Muzili fell asleep after a hard day’s work, trying to keep up her spirits and continue to work the next day, but Le Er pestered her father to go to the "secret passage" with her. Muzili wanted to refuse Le Er, but was shocked by Le Er’s sentence "Guess what I would do if I had hands". Driven by his wife’s encouragement and son’s curiosity, he went to the direction of fireflies … … As soon as this clip came out, it poked the tears of parents. Many parents said that they didn’t expect an animated film to be so real!

Show the true portrayal of adults, and the topic of companionship leads to heated discussion in society.

The topic reflected behind this exposure has aroused deep thoughts from all walks of life. How long have you been away from your children because of work fatigue? Muzi Li in the film plows the fields every day, works for his master, and goes home at night with backache. He just wants to fall asleep and has no time to take care of his son’s dream, let alone accompany him. And isn’t this a true portrayal of contemporary adults? "996", "007" and "KPI" have become invisible shackles on adults. After a day’s work, they are exhausted, and sometimes their children have fallen asleep when they come home from work late at night. On the one hand, the pressure of making money for a living, on the other hand, the responsibility of raising children, coupled with the increasingly fierce involution, has weighed heavily on adults, and accompanying children has become a luxury.

However, accompanying children to grow up is a compulsory course for parents. It is difficult for children without parents to feel love and love life. In reality, we may see that some parents brush their mobile phones even if they have free time, and let tablets and mobile phones act as nannies for the baby; Some parents fill their children’s time with various interest classes, but they never know that their parents’ company can shape their children’s best interests; Although some parents make money day and night to make their children live a better life, they don’t know that while making money, they have already lost the best time to accompany their children in those years. Being busy should not be an excuse. How to accompany children and listen to their voices? I believe parents will find the answer in movies.

The film The Legend of the Erect Elephant will be released nationwide on July 30th. Companionship is the best gift parents give their children. This summer vacation, watch the story of the upright elephant with your children!
