Every autumn, it is the season of centralized buying of air purifiers. This is because PM2.5 pollutants, bacteria and viruses that breed in flying dust and smog are easy to lead to high incidence of respiratory diseases in autumn; Second, because of the cold weather, people began to stay indoors more, and the air quality at home directly affected their health and quality of life.

In this context, on September 9, Mijia air purifier 4Pro was officially launched, which provided a new choice for creating good indoor air. On the basis of removing aldehyde, deodorizing, antibacterial and antiviral functions, it has systematically upgraded the details for the needs of families with babies, which is a veritable "mother-baby optimization".

Filter more thoroughly and breathe more freely.

As a household air purifier, the most intuitive and high-quality function is whether it can purify quickly and let users enjoy fresh air immediately.

Mijia air purifier 4Pro, with its 360-degree surrounded air intake design, delivers up to 8330L of clean air per minute, which is equivalent to 10 square meters of baby room space. In a closed room, it can quickly surround you with clean air in a short time and take you from the cement forest to the natural lawn in a few minutes.

There is air volume, but also quality. The filter element of Mijia Air Purifier 4Pro has a super-large filter paper, and adopts a five-layer high-precision fitting structure. Compared with the old model, the expanded area of the filter paper has increased by 4,000 square centimeters. No matter dust, pet hair, pollen or pm2.5, it can be effectively filtered out, and it is an all-round player who can not only remove dust and resist haze, but also absorb odor.

Will be much more, do it quickly. The competitiveness of Mijia air purifier 4Pro is self-evident, but it still has its unique skills.

Eliminate aldehyde and resist germs, and protect the baby’s safety.

In a series of functions around the upgrade of baby’s respiratory health, aldehyde removal and bacteria resistance are the core. Compared with the previous generation products, the powerful filter element has improved its aldehyde removal ability by 185%, and the removal rate of formaldehyde in one hour is as high as 95.37%, and the removal rate of toluene in one hour is more than 96%, which can effectively block the volatilization of invisible toxic gases in the home. The baby doesn’t live in a formaldehyde room, and the whole family is more at ease.

Its excellent antibacterial and antiviral performance benefits from the antibacterial and antiviral double coating of Mijia air purifier 4Pro, and its resistance rate to airborne suspended bacteria such as H1N1 virus, Escherichia coli and Staphylococcus aureus is as high as 99.99%. It also has a very rare ability to inactivate bacteria and viruses. In dealing with germs, the inactivation effect is obviously more thorough than simple interception. In autumn and winter when colds are frequent, it can effectively protect children with poor resistance and protect their babies.

More intimate details, no burden to use.

Babies who are sensitive to sound, parents who have worked hard all day, and white-collar workers who are under great pressure are all afraid of noise. The feeling of insomnia is Du Jie for people of any age. If the sound of the air purifier is too loud, then the function will discourage consumers. Fortunately, Mijia air purifier 4Pro has done a good job in sound processing, and its operating noise is only 33 decibels, which is more than 10 decibels lower than the noise standard of night living quarters stipulated by the state. Even if you drive it all night, the baby can still sleep peacefully.

There are many similar details, such as the detachable grille at the top, which is easy to clean the fan blades and fans, avoid secondary pollution, and prevent the baby from being injured by mistake. Another example is the simple and clear OLED touch interactive screen, which can display PM2.5 data in real time, and the three-color light bar can directly feedback the indoor air quality, and can also prompt the status of filter element, warehouse door and grille at a glance.

For lazy people and intelligent enthusiasts, automatic optimization and remote control are more exciting. It can automatically optimize the purification speed with one key to the automatic gear. Of course, it is so smart because it has a high-precision laser sensor, which can sensitively detect pollution changes and automatically adjust according to air quality at any time, which is efficient and energy-saving. Of course, it also supports Mijia App to remotely control the switch. People are on the road, there is good air at home, and the intelligent experience comes immediately.

We are most concerned about the use cost of consumables, and of course it has also been taken into account. Generally, the filter element of air purifier fails quickly and is not durable. However, Mijia Air Purifier 4Pro has extended the service life of the filter element to 6-9 months, which is almost 1.5 times that of the ordinary filter element, saving money, not to mention the trouble of frequent replacement, and really carrying out the ultimate cost performance to the end.

In recent years, with people paying more and more attention to the quality of life and air quality, air purifiers are gradually becoming "just needed", especially for families with babies. I believe that a good air purifier 4 Pro can meet most of your needs!

　　At about 10 pm on March 28th, less than half an hour after the new car was released, 50,000 new millet cars were booked.

　　On the same day, Xiaomi Group held a launch conference of Xiaomi Automobile with the theme of "Forward" in Beijing Yichuang International Convention and Exhibition Center, and officially released Xiaomi SU7. Every press conference called "Spring Festival Evening in the Car Industry" makes related topics such as "Lei Jun" and "millet SU7 price" hot searched in Weibo.

　　Conference site

　　Friends sitting in the front row

　　Zhang Jianyong, Chairman of BAIC Group, Wei Jianjun, Chairman of Weilai Automobile, Li Bin, Chairman of Xpeng Motors, He Xiaopeng, Chairman of LI and many other entrepreneurs appeared at the Xiaomi Automobile Conference, which was a rare "famous scene" in the car circle. Some of them are "friends" and some are partners. Whenever Lei Jun talks about the highlights of Xiaomi car on the stage, the live camera will be aimed at them under the stage. At the same time as the press conference, various expression packs have been circulated in the circle of friends.

　　For Xiaomi, a newcomer to the bicycle circle, the new forces are friendly. In addition to several people who arrived at the scene, (), Aouita and other cars also sent their blessings from a distance through Weibo before the conference, and Lei Jun, founder, chairman and CEO of Xiaomi Group, sent a long letter of thanks. In this harmonious atmosphere, Xiaomi Xiaomi SU7

　　"The smartest car within 500,000 yuan"

　　At the press conference, Lei Jun said: "This is the first official appearance of Xiaomi SU7, and it is also the most important moment in my life. Dream cars in this era must have the most advanced intelligent technology and the best driving sense. We hope to build a car that is the most beautiful, the best to drive and the smartest within 500,000 yuan, and build a high-quality car. "

　　According to him, Xiaomi SU7 has 4 color systems and 9 colors to choose from. In terms of selling price, the standard version is priced at 215,900 yuan, the Pro version is priced at 245,900 yuan, and the Max version is priced at 299,900 yuan. In addition, there are Xiaomi SU7 Founding Edition and Xiaomi SU7 Max Founding Edition, and the price remains unchanged, limited to 5,000 units. It can be ordered through Xiaomi Auto App, Xiaomi Auto WeChat applet or Xiaomi Auto retail stores in 29 cities across the country, and delivered as soon as it goes on the market. The founding version will be delivered as soon as April 3, and the standard version, Max version and Pro version will be delivered at the end of April and May respectively.

　　Lei Jun repeatedly emphasized the technical content and material quality of Xiaomi SU7 at the press conference, proving that it is a cost-effective car, and used "far ahead" when talking about technology. In the previous interaction with netizens, I also mentioned "respect technology" many times.

　　"I really can’t afford it."

　　In order to attract users to place orders, in addition to promoting cars, Lei Jun took out the "President’s Signature Benefit" at the press conference-

　　Users who make a reservation before April 30 will enjoy Xiaomi Zhijia Pro and Xiaomi Zhijia Max for life, and will also receive a car smart refrigerator worth 2,000 yuan, a 25-speaker luxury audio worth 6,000 yuan, a Nappa leather seat worth 8,000 yuan, an electric tail wing worth 6,000 yuan, a 20-inch club wheel worth 6,000 yuan and a Michelin pilot worth 9,000 yuan.

　　At the press conference, Lei Jun said many times that these configurations are "all very good", "all delivered", "we will lose if we send them again" and "we really can’t afford to send them", and his expression was heartbroken.

　　"Suggest placing an order as soon as possible"

　　At the end of the press conference, the sales of Xiaomi Automobile officially opened. Yinshi Finance tried to place an order. A salesperson of Xiaomi Automobile told Yinshi Finance that the order is hot at present, and it is recommended to place an order as soon as possible. The deposit is 5,000 yuan. Users can lock it after the test drive is satisfactory, or they can get a refund if they are not satisfied.

　　Soon after, Xiaomi Automobile announced the data: after the open order, the original version of Xiaomi SU7 was sold out quickly, and it broke 10,000 in 4 minutes, 20,000 in 7 minutes and 50,000 units in 27 minutes. The words "sold out" appeared at the bottom of the page. If it is calculated at the price of 215,900 yuan, it will bring nearly 10.8 billion yuan of income after all delivery.

　　However, Lei Jun also took precautions in advance at the press conference, reminding that it may take one or two months from the scheduled time to the pick-up of the car, and sincerely said that he would accept all criticisms. "We will change it immediately if we have any opinions."

　　According to the "2024 China Automobile Consumer Insight Report" released by McKinsey, China consumers’ preference for domestic high-end new energy automobile brands continues to rise, including the advantages of intelligent technology in autonomous driving and intelligent cockpit, which has become the main reason for them to buy. According to the report, consumers’ pursuit of smart technology and re-evaluation of the value of traditional brands are promoting the reshaping of the market structure.

　　"Intelligence is Xiaomi’s strength. Starting from Xiaomi SU7, users can feel today’s smart technology." Lei Jun said that the official release of Xiaomi SU7 also marks that Xiaomi’s strategy of "all people, cars and homes are ecological" is moving from "complete closed loop" to a new stage of "full opening". However, there is still only one sea blue car at the press conference, and the offline stores are only static display at present, and most consumers have not had a chance to test drive. Whether "the best looking, the best driving and the smartest" will be a impossible trinity, or whether it can have both, will be answered after the new car is delivered.

　　On October 18th, the website of Jiayuguan Health and Health Commission reported that Shaanxi Province reported two tourists whose nucleic acid test results were positive and arrived in Jiayuguan by car from Ejina Banner, Inner Mongolia at around 16: 00 on October 14th, 2021. At 9: 00 on October 15th, two people took the initiative to go to Jiayuguan Traditional Chinese Medicine Hospital for nucleic acid testing, and the hospital conducted a 10∶1 mixed test according to the requirements of normal testing. After the sampling was completed, two people returned to the hotel to check out and went to Jiayuguan Airport.

At 11: 07 on October 17th, I received the Notification Letter from Shaanxi Provincial Center for Disease Control and Prevention. At 17: 00 on October 16th, the nucleic acid test result was positive, and it was rechecked by Shaanxi Provincial Center for Disease Control and Prevention. At present, I am observing in the isolation ward of the Eighth Hospital of Xi ‘an.

Do you have any plans to change an AI mobile phone in 2024? Maybe many people still don’t understand, what is called AI mobile phone and what it can do.

At present, major brands in the market, including OPPO, vivo, Meizu, etc., have begun to push AI mobile phones wildly, and their main functions include AIGC elimination.(A retouching function), AI call summary(Key Points of Generating Call Records with One Click)Wait. But don’t worry, the AI snacks pushed by Muji are alive and well, so it’s not too late to buy them later.

Our view is:You don’t have to buy a concept, but you need to see if there is a "truly subversive AI application you need" in your mobile phone.Just don’t buy another Mito phone.

First, the store visited the AI ? ? mobile phone

Beijing East Fourth Ring Road, Huawei, OPPO, vivo and other brand mobile phone stores are lined up. For AI mobile phones, OPPO and vivo should be considered to run faster.

At the OPPO counter, OPPOFind x7 UItra, which was launched in January this year, focuses on the concept of AI mobile phone. What attracts me most are these two functions.

One is the elimination of AIGC. Many people have an annoyance when taking photos in online celebrity scenic spots, that is, "random passers-by". The AIGC elimination function is to identify and eliminate people, objects, etc., and then the AI model that comes with the mobile phone can generate other filling pictures, saving time and effort.

Figure | AIGC elimination demonstrated at OPPO official website

The other is the AI call summary. Presumably, busy modern people have a "common fault". When they hang up a sudden phone call, they completely forget what they just said.

The main function of this function is to intelligently identify the content of the call and generate a summary of key information, so you don’t have to go back and ask and scold repeatedly.

Figure | AI call summary demonstrated on OPPO official website

As for other AI functions, including intelligent generation of pictures, dialogue with smart cloth, intelligent generation of ID photos, etc., it is somewhat similar to Baidu’s Wenxinyige, Siri and Ali’s wonderful duck camera, and the new ideas are not enough for me.

In Taobao’s OPPO flagship store, its AI mobile phone sales currently exceed 10,000+,and the price ranges from 3,999 yuan to 4,999 yuan. In JD.COM, the sales volume of this model is 20,000+.

Compared with OPPO, vivo’s AI mobile phone was launched earlier. Last year, two models, vivo X100 and vivoX100 Pro, were released. Its AI function entrance is mainly based on the small V assistant and jovi voice developed by the big blue heart model. Through this assistant, AI subtitles, screen reading, global translation, listening to songs and recognizing songs can be realized.

One of the functions that impressed me deeply is that in addition to the traditional "voice assistant" function, the small V assistant dialog box has added a creative function-in fact, it is similar to Baidu’s literary mind. As long as you enter a paragraph of text, it can make pictures. It can also take photos in real time and generate photos of various styles. It is said that this creative function can generate documents, PPT and mind maps after upgrading in the future.

The pricing of Vivo X100 and Pro models also ranges from 3,899 yuan to 5,999 yuan. It may have been sold earlier, with X100 selling over 30,000+on Taobao platform and 100,000+on X100 Pro platform.

As for Huawei, the industry believes that Huawei P70 will be the most concerned AI mobile phone in 2024. But according to the latest news, it may be postponed until April.

Seeing that many brands push AI cameras, other consumers in the store with me asked a question: AI mobile phones can generate registration photos, "Is it good, but will the relevant systems recognize the photos generated by AI?"

This little problem has no solution for the time being, but it also brings you a thought:A series of pictures and documents generated by AI also face a series of frictions and adjustments from society, law and ethics.In order to coexist well.

For example, many recent incidents of resurrecting the dead with AI have not been approved and authorized by their families, and curiosity has caused secondary injuries. These AI functions on mobile phones are the same, and they need a lot of discussion from the whole society.

Second, under the AI ? ? mobile phone, some people poured cold water on it.

AI mobile phones are actually not new. They were briefly popular between 2017 and 2018. At that time, manufacturers focused on AI chips, which could run pictures, speech recognition, AI photography and other applications.

HONOR, in that year, launched Glory View 10, with the slogan "Your first AI mobile phone". Now you can also find AI mobile phone articles published in 2018 with titles such as "Counting Huawei’s five AI mobile phones" and "Five AI mobile phones carefully built by Huawei".

However, although manufacturers were excited at that time, consumers seemed to be very calm. The reason was summarized as the lack of epoch-making subversive applications, and the AI concept did not save the global mobile phone from entering the stock market at that time.

In the blink of an eye, six years later, in the second half of last year, AI mobile phones began to move again, this time thanks to the hot generative AI.

In addition to the founders such as Baidu and Ali, mobile phone manufacturers have also refined AI and successively released large models for mobile terminals.

Such as Xiaomi’s MiLM, OPPO’s Andean model, vivo’s blue heart model, Meizu’s Aicy AI, glory’s magic model, Samsung’s Gaussian model, and terminal products equipped with large models.

This year, it seems natural, or it is the industry’s usual "grab the commanding heights". Some mobile phone manufacturers began to call their own mobile phones equipped with large model capabilities "AI mobile phones".

On the occasion of the Lunar New Year in 2024, Liu Zuohu, senior vice president and chief product officer of OPPO, appeared in a promotional video, announcing that "OPPO officially entered the era of AI mobile phones."

Vivo mobile phone also announced that vivo S18 series is "the first batch of AI big model mobile phones in the world", claiming that the self-developed Blue Heart big model has covered its 25 models, and more than 20 million users have experienced the big model function of vivo.

The most radical is Meizu. Before the end of the first month, Meizu suddenly announced that it would stop making "traditional mobile phones", All in AI. The newly released Meizu PRO 21, Meizu officially no longer calls it a mobile phone, but an "open AI terminal".

The drama of AI mobile phone is not only sung by domestic manufacturers.

Samsung also announced its entry into the "new era of mobile AI" with a new generation of Galaxy S24 mobile phones.（New Era of Mobile AI）.

Recently, Apple, which has always been cautious, also "abandoned the car to protect AI", disbanded the car-making team that was established for ten years, and instead increased the development of generative AI.

According to many sources, Apple will promote AI capabilities as the focus of the iPhone 16 series. On March 15th, Apple officially announced a series of multi-modal large language models with 30 billion parameters.

Behind the active push of many manufacturers is actually the sense of crisis of mobile phone manufacturers.In doing business, it is important to seize the commanding heights and the right to speak in advance. In 2024, it has become the "first year of AI mobile phone" in the eyes of various manufacturers.

Chen Mingyong, founder and CEO of OPPO, released an internal letter with the theme of "Opening a new era of AI mobile phones" on the first day of the new year on February 18th this year.

Then, Liu Zuohu sounded the alarm for his peers: "In 2024, if smartphone manufacturers don’t lay out large models, there will be no play, which will definitely affect market competitiveness."

Figure | Liu Zuohu’s answer to "Is AI mobile phone a gimmick or a future"

Zhao Ming, CEO of HONOR, said even more seriously that it is too late to be All in AI now: "You will be all in AI this year … The gap will get bigger and bigger."

It seems that the sun is shining, but there are also many boos in the industry.

Lu Weibing, president of Xiaomi Group, bluntly said that "AI mobile phone is a gimmick". For friends who speculate on AI mobile phones, it is inevitable that some people say that AI is a ubiquitous ability. When you can’t feel AI, it is the greatest value of AI. Talking about AI every day shows that there is no AI ability.

Zhao Ming, CEO of Glory, also believes that most friends only tinker with some AI applications, and some slogans such as All in AI are just marketing. Of course, this does not prevent him from thinking that HONOR loaded with MagicOS 8.0 can be defined as a "real AI mobile phone".

Third, how sexy the concept of AI mobile phone is, how skinny the reality is.

Generative AI is indeed becoming the future development direction, so let’s not go against the trend and anti-science. But is the era of AI mobile phones really coming?

Here, let’s return to our original heart and explore what an AI mobile phone is.

The application of AI function modules in mobile phones is nothing new. Many functions in your mobile phone, such as voice assistant, voice recognition, multilingual translation and facial recognition, all use AI. But obviously such a mobile phone is not worthy of being called an "AI mobile phone".

At Gartner, a technology consulting firm（Gartner）In the definition of "AI mobile phone"（GenAIsmartphones）Have the software and hardware that can seamlessly integrate and effectively execute the related functions and applications of generative AI. AI mobile phone can run a basic big model that can generate new content, strategies, designs and methods locally. "

That is to say,In industry cognition, AI mobile phones should be able to run the basic big model locally-the end side.（on-device）Big model.The end-side large model is completely loaded in the mobile phone, and it can be used even in flight mode without connecting to the cloud. The advantages are high speed, low power consumption and low cost, but the disadvantages are also fatal-performance is reduced.

In other words, people are at the machine, and the machine is at the end. The big model is there, and it is on call.

At present, mobile phone manufacturers such as vivo, Samsung, OPPO and Glory have built-in end-to-end models in their mobile phones.

OPPO has a large Andean model with 7 billion parameters at the end; Glory also added a self-developed magic model with 7 billion parameters to MagicOS 8.0 operating system, and vivo also had a blue heart model with 7 billion parameters. Samsung’s Galaxy S24 series also added an end-side model Galaxy AI.

The end-to-end large-scale arms race is in full swing. In the public relations drafts of various companies, their functions are undoubtedly leading and epoch-making. But how sexy the AI mobile phone in the public relations draft is, how skinny the AI mobile phone in reality is.

At present, the main AI functions of the "AI mobile phone" on the market are nothing more than generating graphics and text, intelligent search, picture editing, real-time translation, voice transcription, auxiliary chat, voice assistant and so on. The key point is that these functions can be completed by downloading third-party Apps from the app store without the built-in big model, and the effect is even better than the system itself.

PCHome evaluated mobile phones with large model functions on the access side, such as Meizu 21 PRO, OPPO Find X7 Ultra, vivo X100 Pro, and frequently overturned when trying related functions.

For example, ask Aicy voice assistant of Meizu mobile phone "When will Meizu mobile phone support AI", and it only answers the current date;

Let the small cloth assistant of OPPO mobile phone draw "to divert the tiger away from the mountain", it can only draw a tiger. The image generation function of vivo X100 Pro is single in style and uneven in quality, which is not as good as the free AI image generation tool on the market.

In the cross review of another AI mobile phone, the image editing function promoted by an AI mobile phone can’t compliment the effect of removing redundant characters with one click, and the afterimage is very obvious. What’s more, for most users, this function may not even be as practical as the one-click beauty of Meitu Xiu Xiu or Tik Tok Filter.

To sum up, even the standard basic skills of large models on the market are not up to standard, not to mention the higher-level AI functions mentioned in the publicity.

This can’t help but remind people of the Mito mobile phone that came out in 2013. Although it is not the same species as AI mobile phone, its main function can be realized by downloading a Mito Xiu Xiu. Why buy a new mobile phone?

Remembered that sentence, "the business ability is not enough, and it is easy to be optimized in the workplace."

Fourth, the AI ? ? mobile phone must be in the sky, and there are three mountains.

As a family, the current mobile phone is still far away from the real AI mobile phone era. In order to climb the top of AI, the mobile phone industry still needs to cross three mountains-innovation is not subversive, hardware is not up to standard, and the audience can’t buy it, so it is possible to enter the era of AI mobile phones.

First of all, is there any subversive innovation in the first mountain? Subversive innovation means drastic changes in product forms and user habits.

In the field of personal computers, from the command line interface to the graphical interface, the way people use computers has changed from typing codes on the keyboard to controlling the interface at will with the mouse. In the field of mobile phones, functional machines have been transformed into smart phones, and the way people use mobile phones has changed from keyboards to touch screens.

In the era of AI mobile phones, at least there must be similar revolutionary innovations.

For example, from a graphical user interface（GUI）Become a natural language user interface（NLUI）People use dialogue to control their mobile phones; Or, the generative AI completely breaks the barrier between the mobile App and various functions. Or, a phenomenal end-to-end model similar to Android or iOS appears and becomes the underlying architecture of mobile phones …

We are not a prophet, and we don’t know what kind of subversive change it is, but we know that the current AI mobile phone is definitely not. Generative AI can indeed improve the efficiency of some office, study and living abilities on mobile phones, but it is not qualified to become a subversive innovation that promotes intergenerational change, and there is still a long way to go.

This involvesThe second mountain on the AI ? ? mobile phone, the hardware ceiling.

Full-scale models such as ChatGPT and ERNIE Bot work miracles by themselves, and the process of training and using consumes huge computing power and electricity.

It is said that the training of GPT-4 used 1 ~ 25,000 A100 chips. Musk, the cross-border richest man who has been paying close attention to generative AI, also estimated that GPT-5 may need 30,000 to 50,000 H100. The domestic Wenxin Big Model 4.0 was also trained with Baidu’s own flying paddle platform Wanka Cluster.

After opening the service to the public, in order to meet the simultaneous use of a large number of users, strong hardware support is also needed. It is estimated that ChatGPT needs to use 30,000 GPUs to deal with millions of user requests every day.

Such a huge demand for computing power directly pushed the share price of NVIDIA, which sells shovels, up to $2 trillion at one time, surpassing Google and Amazon and ranking third in the US stock market.

The big model is still a fierce electric tiger. A few days ago, a piece of news rushed to Weibo for hot search: the daily power consumption of ChatGPT is equal to that of 17,000 households in the United States. The average daily electricity consumption of an American family is 29 kWh, while the daily electricity consumption of ChatGPT exceeds 500,000 kWh.

With the current mobile phone hardware foundation, it is really hard to bear the "big" of the big model, and it needs to be optimized specifically for mobile phones.

Since the second half of last year, Qualcomm, MediaTek and other chip manufacturers have frequently made efforts to develop large-scale end-to-end hardware.

In October 2023, Qualcomm released the first Snapdragon 8 Gen 3 chip specially built for generative AI, which can run a large model with 10 billion parameters on mobile phones. Glory Magic6 Pro, Xiaomi 14 Pro, OPPO Find X7 Ultra and other mobile phones use this chip. MediaTek released Tianji 9300 chip at the end of 2023, claiming to support a large model with a maximum of 33 billion parameters.

Figure | Qualcomm’s Snapdragon 8 Gen 3

The A100 chip running GPT has a memory of 80G, and no matter how many mobile phones are configured, it is not enough.

For example, the newly launched GeForce RTX 40 Super in NVIDIA has an AI engine power of 836 TOPS per second. In contrast, Qualcomm Snapdragon 8 Gen3, the strongest mobile phone terminal, has only 73 TOPS per second, a difference of more than ten times.

So,Full-scale cloud model, the mobile phone can’t move locally.At present, the large-scale end-to-end model, with parameters ranging from tens to tens of billions, is small and exquisite compared with the large-scale cloud model with hundreds or even trillions of dollars.

The most common way to experience the most advanced generative AI on the mobile phone is through the cloud, where users input instructions on the mobile phone, then upload them to the cloud for processing and then return them to the mobile phone. This process is time-consuming and laborious, and subject to the network, the experience is not very friendly.

To experience a more silky large model on a mobile phone, a specially optimized end-to-end large model is needed, which will inevitably shrink in performance.

Even the full-scale cloud model is not mature enough, and all kinds of hallucinations and bugs often appear. The scaled-down end-to-end model will naturally seriously restrict the performance on the AI ? ? mobile phone.

Even if it is immature, it must be hard. In addition to occupying a position in publicity, mobile phone manufacturers have a more practical purpose: to promote mobile phone sales through the gimmick of AI.

But this will encounterThe third mountain that blocks AI mobile phones: the audience may not buy it.

The background is that the economy is going down and the sales of mobile phones are declining. According to International Data Corporation（IDC）In 2023, China’s smartphone shipments were about 271 million units, down 5% year-on-year, the lowest in nearly a decade.

In 2024, the situation did not improve. According to the research organization Counterpoint Research, the sales volume of smart phones in China dropped by 7% in the first six weeks of 2024, and the sales volume of most mainstream mobile phone manufacturers showed a large-scale decline, among which OPPO fell by 29%, Apple fell by 24%, vivo fell by 15%, and Xiaomi fell by 7%. Only Huawei and Glory achieved growth.

In terms of camera, size, chip, battery, screen and other mobile phone software and hardware parameters, mobile phone manufacturers have no volume, and consumers who have tightened their pockets have long been less cold. So mobile phone manufacturers regard generative AI as the next lifeline.

But the cold reality is that consumers don’t buy the AI ? ? pie painted by mobile phone manufacturers, at least for now.

I visited the official flagship stores of OPPO and vivo near the East Fourth Ring Road in Beijing offline, and found that the AI ? ? mobile phone is actually not the focus of publicity. The clerk of the mobile phone shop also said that customers are still mainly concerned about the performance of mobile phones such as taking photos, chips and screens, and few people will take the initiative to pay attention to the AI function. Even if the clerk takes the initiative to mention it, he is usually not interested. Offline interviews with media such as Economic Observer and Titanium Media also received similar feedback.

It is well understood that compared with the stars and seas where people in the industry are keen to discuss AI technology, ordinary consumers are more concerned about: Is AI on mobile phones really that powerful? Judging from the capabilities provided by the current AI mobile phone, the answer may not be.

Five, AI mobile phone, why is it a mobile phone, the brain hole can be bigger.

Past experience tells us that it is not the faster carriage that defeats the carriage, but the car;Similarly, why is it a stronger mobile phone instead of a smart phone?

It is entirely possible that it is another form of AI hardware, replacing the smart phone form that has been popular for more than ten years. Recently, there have been several products that have broken through the boundaries of smart phones, which have aroused widespread concern.

For example, Rabbit, an AI company, has launched a palm-sized smart device, Rabbit R1, which is mainly driven by natural language. Press the dialogue button and you will get a response within 500 milliseconds. This equipment sold 50,000 units in two weeks.

Humane, a startup company, has released a product AI Pin embedded with OpenAI technology, which removes the screen and relies on laser projection and gestures to operate. Time magazine named this AI hardware as "one of the top 200 inventions in 2023".

Figure | AI hardware AI Pin operated by projection and gesture

Deutsche Telekom and Brain.ai jointly launched a product called T-Mobile, which is characterized by no App, and the main interface is an AI assistant, which is controlled through dialogue.

Of course, these devices are still in the development state more or less, and it is still early to put them into the market on a large scale.

Although the generative AI in sturm und drang in the past year, there was even a phenomenon of "big satellite release", and people kept announcing that their large-scale model capabilities "caught up" or even "surpassed" GPT3.5 or even 4. But so far, apart from ChatGPT itself, there is no phenomenal AI application for all.

In other words, the applied ecology on the basic big model is still in its infancy, and how big the fruits of the big model can be, depends on nature. However, the ability of the end-side large model carried by the mobile phone is always locked by the basic large model. In this case,Advocating AI mobile phones is more of a public relations technique.

The turning point of domestic AI mobile phones may have to wait until the international head model company opens its own products.

This article comes from WeChat WeChat official account:True reason laboratory (ID: zhengulab), Author: Feng Nuo, Editor: Gong Zheng

As expected in the market, the new energy subsidy policy was officially released in 2019. Different from the previous 20% rebate standard, the subsidy standard in 2019 will be reduced by 50% on average on the basis of 2018.

The introduction date of the subsidy scheme for new energy vehicles can be said to be later than one year. The 2017 plan was introduced on December 30, 2016, the 2018 plan was introduced on February 13, 2018, and the 2019 plan has reached March 26, 2019. "yet we called and urged a thousand times before she started toward us, still hiding half her face from us behind her guitar" is really appropriate to describe the new energy subsidy policy in 2019.

Since the wind of the sharp decline in subsidies for new energy vehicles in 2019 has been blowing for several times, different programs have been passed from the end of 2018 to March 2019, and the industry has long had psychological expectations for the programs launched by the central government. Although this plan is very strong, it is all expected, even better than expected.

This time highlights several key points:

Subsidized standard passenger cars fell by 47-60%, and plug-in passenger cars fell by 55%; New energy buses dropped by 49-56%, and new energy special vehicles dropped by 45-80%. Cancel land compensation and subsidize infrastructure such as charging piles/hydrogen refueling stations instead.

The overall adjustment is very strong, which has great cost pressure for enterprises. The product lines of some enterprises will be greatly adjusted, and Ferrous lithium phosphate may make a comeback due to its cost advantage.

Despite the cancellation of land compensation, the subsidy policy for new energy buses will be introduced separately, and the determination of urban electrification will not be reduced.

Since electric vehicles have met the market conditions, the focus of policy support has shifted to fuel cell vehicles. Fuel cell vehicle subsidies will be refined according to different technical standards, and fuel cell subsidy policies will be introduced separately.

In the book, the extended range is classified as pure electric, and some experts have also mentioned supporting extended range vehicles after plug-in development to a certain extent. However, in this subsidy policy, the extended program subsidy is still classified as plug-in, and the prospect is worrying.

The payment method of subsidies was adjusted, and the punishment mechanism for safety accidents was put forward.

The following is a detailed interpretation of several key points of this subsidy policy.

One,Central subsidy adjustment

The maximum subsidy for all types of vehicles has decreased significantly, and the endurance and energy density have changed from "encouraging high endurance/high energy density" to "punishing low endurance/low energy density", and at the same time, the minimum energy density threshold has been raised.

(1) New energy passenger cars

The subsidy for passenger cars has changed to two grades, with pure electric slope retreat of about 47%-60% and plug-in slope retreat of 55%.

The threshold of energy density has increased from 105Wh/kg to 125Wh/kg, which requires continuous improvement, and the subsidy multiple has been lowered.

The minimum is raised from 150 kilometers to 250 kilometers, and the standard of energy consumption subsidy multiple is adjusted, which obviously improves the requirements for overall energy saving.

By canceling the subsidy below 250 kilometers, the subsidy multiple of low energy density will be reduced, and enterprises will be encouraged to produce cars with high energy density and high endurance. Combined with the industrial policy of low-speed electric vehicles, low-speed electric vehicles may be responsible for the shorter range below 250 kilometers, and it is difficult for A0 and A00 electric vehicles to compete with low-speed electric vehicles in cost.

Due to the decrease of subsidies and the increase of energy density in Ferrous lithium phosphate, the cost of Ferrous lithium phosphate shows certain advantages, and some enterprises may switch from Sanyuan to Ferrous lithium phosphate in low endurance vehicles.

Some enterprises with relatively backward technology or lack of industrial experience will be under great cost pressure, thus being forced to raise the price of automobile products, reducing the market competitiveness. At present, new car-making forces such as Tucki and others have raised the price of their products.

The leading enterprises have abundant funds and leading technical strength, and have full expectations for subsidies. They will continue to promote the development of vehicles with high cruising range, reduce costs by optimizing design and production, and continuously improve market competitiveness. Therefore, the impact on leading enterprises is not so great, and the mainstream A-class and above vehicles are less affected. The selling prices of Geometry A and Aions newly introduced by Guangzhou Automobile Co., Ltd. and Guangzhou Automobile Co., Ltd. did not reflect the obvious influence of subsidies, while Weimar and Guangzhou Automobile Co., Ltd. introduced the strategy of price protection.

The most important thing is to reduce the amount of subsidies, promote the marketization of new energy vehicles, eliminate the fittest for enterprises, and concentrate the automobile production capacity on advantageous areas and enterprises.

(2) New energy buses

The gradient is 49%-56%, and the minimum energy density is required to rise from 115Wh/kg to 135Wh/kg.

The energy efficiency and subsidy coefficient were adjusted, and the requirement was increased by 5 percentage points.

New energy buses may be rushed to install during the transition period.

(3) The new energy trucks have been adjusted in detail.

By simply subsidizing the battery capacity, the weight classification is increased. The maximum subsidy is reduced from 100,000 yuan according to different types, and the reduction range ranges from 45% to 80%.

At the same time, the minimum energy density is increased from 115Wh/kg to 125Wh/kg, and the subsidy coefficient is adjusted.

There are two points worthy of special attention in terms of new energy trucks.

1) The subsidy category of "special purpose vehicle" was cancelled, and the classification of total quality of freight cars was increased.

This means that the market develops from logistics vehicles to larger trucks, and even pure electric heavy trucks appear; The subsidy policy for new energy special vehicles was cancelled.

2) The subsidy category for trucks has been added.

Increase market choices, and trucks with a total mass of more than 12 tons can choose the technical direction of plug-in hybrid to adapt to more market changes.

Second, cancel local subsidies and promote fair market development

This is a continuation of the spirit conveyed in the Regulations on Investment Management of Automobile Industry and the Implementation Plan for Further Optimizing Supply, Promoting Steady Growth of Consumption and Forming a Strong Domestic Market (2019), breaking local protection, promoting market-oriented development and creating a level playing field.

At the same time, we will continue to improve the market consumption environment by subsidizing infrastructure construction, and support the development of new energy vehicles through indirect financial subsidies. However, hydrogen refueling station enterprises get development opportunities and can focus on related enterprises.

Despite the cancellation of land compensation, new energy buses will be introduced by a separate subsidy policy, showing the importance attached to urban electrification.

Third, fuel cell vehicles are listed separately, and the degree of attention is unprecedented

Fuel cell vehicles are in a critical period of technological development and market introduction. In the past, the subsidy policy for fuel cells was too simple, which only stipulated the minimum rated power and the minimum cruising range, which also led to the design of the subsidy line for automobile products in the announcement catalogue, all of which were 30KW.

The fuel cell subsidy policy was postponed, presumably in order to refine the subsidy policy and avoid the previous design of fuel cell vehicles under the pressure of subsidy line and the road of pursuing high energy density and ignoring safety like electric vehicles again.

Fourth,Extended-range electric cannot be classified as pure electric.

The extended subsidy policy is still classified as plug-in hybrid. The Investment Regulation of Automobile Industry classifies the investment projects of extended-range electric vehicles as pure electric vehicles, which is considered by many people in the industry as a signal of the rise of extended-range electric vehicles, because the advantages of extended-range electric vehicles can only be reflected when compared with pure electric vehicles, but the competitiveness is weak when compared with plug-in hybrid vehicles.

The subsidy policy for the extended range cannot be classified into pure electric vehicles, so the development prospect of the extended range is worrying, and the "ideal" of the extended range may be "cool".

Five,Emphasize supervision and safety.

Supervision is divided into two aspects: authenticity and security.

Authenticity is achieved by monitoring the operating mileage and adjusting the settlement method. Starting from 2019, for vehicles with operating mileage requirements, a part of subsidy funds will be paid in advance after the sales are registered, and the vehicle enterprises will apply for subsidy liquidation after meeting the operating mileage requirements. If the operation does not meet 20,000 kilometers within 2 years from the date of registration, no subsidy will be granted, and the pre-allocated funds will be deducted at the time of liquidation. This gives enterprises more abundant liquidity and more flexibility to cope with market changes.

Safety emphasizes the consistency of safety accident prevention and product production. The competent authorities of the industry will speed up the establishment of a normal mechanism for product safety monitoring and "consistency" sampling inspection. Suspension or cancellation of vehicles with major safety accidents caused by product quality or with major quality defects identified by relevant departments, and corresponding suspension or cancellation of financial subsidies.

Hydrogen Cloud Chain believes that with the rapid expansion of China’s new energy automobile industry, low-end enterprises that rely on subsidies to survive are doomed to be eliminated, and infants who are breastfeeding will eventually be "weaned". How to ensure quality is the key to "survival".

　　() The Record Form of Investor Relations Activities was released on February 22nd, and the company was investigated by 14 institutions on February 22nd, 2024. The types of institutions are insurance companies, others, fund companies and securities companies. The main contents of investor relations activities are introduced:

　　Q: How is the company’s recent operation?

　　A: The company has disclosed the annual performance forecast for 2023, and the company’s operation is in good condition. Please pay attention to the subsequent 2023 annual report for specific operating data.

　　Q: What is the company’s customer structure? What are the key customers to develop in the past two years?

　　A: On the whole, the top five customers of the company are (), Geely, FAW East Machinist, Nanyang Xijia and Great Wall. From the stabilizer bar customers, the top three customers are Geely, BYD and Changan. In 2024, the company’s development of customers is on the one hand the self-increment of old customers such as BYD, Changan and Chery, and on the other hand the new development of foreign capital, joint ventures and new power brands.

　　Q: What is the company’s product planning layout and release rhythm?

　　A: The company’s production capacity is being released at the normal pace. The spring end released about 30% of the production capacity last year, while the stabilizer end has been built at a faster pace due to urgent demand. Two production lines have been launched last year, and four more production lines are expected to be launched this year.

　　Q: What is the production capacity of valves and special-shaped springs?

　　A: The production capacity construction of valves and special-shaped springs is continuous, and the production capacity has increased compared with the past. At present, the company’s focus is still on suspension springs and stabilizer bars. After the subsequent production capacity and demand of suspension springs and stabilizer bars are balanced, other categories will be further expanded.

　　Q: What is the change trend of gross profit margin of springs and stabilizer bars?

　　A: The gross profit margin of the spring is similar to that in the past. The stabilizer is in the early stage of R&D investment, which involves a long development cycle and high R&D expenses, which also leads to its insignificant gross profit margin. However, the stabilizer bar has been mass-produced, and the income of stabilizer bar is on the rise, and the increment and growth rate are very fast, and it will continue to grow. Under the influence of economies of scale, the gross profit margin will gradually move closer to the spring.

　　Q: In the field of industrial robots, what is the unit price of the company’s products?

　　A: The supporting part of the industrial robot company is around a group of 1000 yuan.

　　Q: What is the opportunity for the company to support the industrial robot field?

　　A: The company’s support for industrial robots can be traced back to several years ago. On the one hand, the company is actively exploring non-automotive fields, on the other hand, the other side also has the intention of cooperation. It took a long period from qualification certification to product testing and debugging, and it was not until recent years that mass production began. The springs supplied by the company on industrial robots are mainly installed in the balance cylinder, which is equivalent to the function of a lever, which can reduce the demand for motors and power, and there are also some small springs.

　　Q: What is the proportion of BYD and Geely?

　　A: In BYD, the company’s suspension springs account for about 70%, and the stabilizer bar is in the climbing stage, currently accounting for more than 10%. In Geely, because there are two ways to supply suspension springs, the proportion of suspension springs is similar to that of BYD, and the stabilizer bar is around 30%.

　　Q: At present, BYD Company accounts for a relatively high proportion. Will the company continue to increase this proportion?

　　A: The company is also adjusting its strategy internally. In the past two years, the fastest development of the company is the automobile industry. However, our philosophy is not to excessively concentrate a product in an industrial chain, just like the concept of not putting eggs in the same basket. It is necessary to spread risks to make the whole industrial structure safer and make the fluctuation of a certain customer or an industry relatively weakened.

　　Q: Will the company have capital expenditure in the future?

　　A: The company will have an investment plan in the future, which will be disclosed in time.

　　Q: What is the supply mode of suspension springs?

　　Answer: The front spring is generally supplied by the shock absorber factories such as FAW Dongji, Wandu and Nanyang Xijia, and the rear spring is generally directly supplied to the main engine factory, which is mainly determined by the type of shock absorber equipped with the vehicle model.

　　Q: The raw material of the company’s products is steel. Does the price fluctuation of steel have a great influence on the company?

　　A: There are two kinds of purchasing modes at the steel mill end, one is the price-locked purchasing mode, and the other is the floating purchasing mode. If the subsequent steel price rises, the company will increase the volume in the locked-price procurement mode, and if the subsequent steel price falls, the company will increase the volume in the floating procurement mode.

　　Q: Is there any development of non-car-end springs in the future?

　　A: The company has always had the spring business of non-automobile plate, such as rail transit, electrical energy and so on. At present, this part is relatively small.

　　Q: What are the main competitive advantages of the company?

　　A: The company can take root in this field, mainly because of our independent research and development of materials, with many years of technical accumulation and precipitation. Through cooperation with domestic spring steel enterprises, the company will carry out the heat treatment process of spring steel after the steel mill provides the masterbatch, thus improving the performance of materials. It has a unique competitive advantage in the market to meet the requirements of high performance and light weight of automobile springs.

　　Q: Where is the company’s future performance increment?

　　A: The stabilizer bar will still be the incremental point in 2024.

　　Q: Is there a difference in the manufacturing process between the spring and the stabilizer bar?

　　Answer: Both the spring and the stabilizer belong to the functional parts of the automobile chassis, and the materials used are basically spring steel. The underlying technology has certain commonality logically. Spring and stabilizer are similar in main processes, such as molding, heat treatment, shot blasting, surface coating and so on, and the process logic is very similar.

　　Q: What is the bicycle value of spring and stabilizer bar?

　　A: A car needs four suspension springs. The price of a traditional fuel car is between 130 and 200 yuan. The front and rear stabilizer bars need to be used in a car. The price of a traditional fuel car is between 120-160 yuan. Compared with the traditional car, the new energy car’s kerb quality is increased, so the bicycle value is increased by 20-30%.

　　Q: Will downstream manufacturers consider making their own springs?

　　A: There have been precedents. Some manufacturers made their own springs, but in actual production, they found that the input and output were not equal. Later, they stopped making their own springs and chose to use them outside.

　　Details of participating institutions are as follows:

[Original] Text/Xi Yan

In the film and television investment contract, the order of investment payment and startup is not clear, and the parties have disputes about it. The performance order of a bilateral contract directly affects the exercise of the parties’ legal right of defense. The order of performance is a matter of performance mode. If the agreement on the way of performance is unclear, it should be determined according to the legal provisions or trading habits. If it is still uncertain, it should be determined in a way that is conducive to achieving the purpose of the contract.

appoint

On August 30, 2021, Party A and Party B signed the Agreement on Joint Investment and Production of TV Series, which mainly stipulated: 1. Party A is the project master of TV Series, fully responsible for organizing the production, publicity and distribution of the drama, and Party B invests in the drama in the form of venture capital. 2. The total budget of the play is RMB 250 million. 3. The starting time of the play is expected to be September 20th, 2021. 4. Party B contributes capital in cash, with an investment amount of 50 million yuan only, and enjoys 20% of the total income of this project. 5. Payment time of funds: (1) Within 15 working days after the signing of this agreement, Party B will pay 20 million yuan; (2) Five natural days before the play starts, Party B pays 20 million yuan; (3) Party B shall pay 10 million yuan within 30 natural days from the date when the play is turned on. 6. As the executive producer of the drama, Party A is fully responsible for the production progress of the drama, and plans to start the drama no later than September 20, 2016.

fulfil

After the contract was signed, Party B did not pay the investment. On September 27th, 2021, Party A sent a reminder letter to Party B, urging Party B to pay the investment amount of 20 million yuan. B didn’t pay after signing the dunning letter, and A didn’t turn it on. Party A thinks that Party B’s failure to pay the investment funds as agreed constitutes a breach of contract, and claims that Party B shall bear the liability for breach of contract.

dispute

Party B claims that Party A should start the machine first, and then pay the first investment, and Party B has the right to refuse its payment request if Party A fails to perform the startup obligation. B’s exercise of the right of defense before performance does not constitute a breach of contract. Party A thinks that Party B should fulfill its capital contribution obligation first, and its startup obligation comes later.

question

How to determine the order of performance of A’s startup obligation and B’s investment payment obligation?

comment on and analyze

As for the payment method of B’s funds, the contract stipulates that B’s funds will be paid in three installments, the first payment will be made within 15 working days after the signing of the agreement, that is, before September 20, 2021, the second payment will be made five days before the startup, and the third payment will be made within 30 days after the startup. The payment of the second and third funds is conditional on the startup. For the start-up, the contract stipulates that A plans to start the play no later than September 20, 2021. There are two expressions of "plan" and "no later than" in the aforementioned agreement. There are two explanations for its meaning: starting the machine before September 20, 2021 is a definite obligation, and Party A should complete the startup task before this time, and starting the machine before September 20, 2021 is only a tentative plan, not a definite obligation. For the explanation of its meaning, this paper tends to the latter. The reasons are as follows:

First of all, from the perspective of contract interpretation, if there is an interpretation of private party’s expression of will, the meaning of the expression of will should be determined according to the words used, the nature and purpose of the relevant clauses, habits and the principle of good faith. Article 3 of the contract stipulates that the starting time of this drama is expected to be September 20, 2021. The startup time agreed in this article is the estimated time. According to Articles 3 and 6 of the contract, September 20, 2021 is the estimated startup time.

Secondly, from the point of view of contract loophole filling, the sequence of startup and investment payment obligation involves the issue of performance mode. Article 510 of the Civil Code stipulates that after the contract comes into effect, if the parties have not agreed or clearly agreed on the quality, price or remuneration, place of performance, etc., they may supplement it by agreement; If a supplementary agreement cannot be reached, it shall be determined in accordance with the relevant provisions of the contract or trading habits. Article 511 stipulates that if the parties’ agreement on the contents of the relevant contract is unclear and cannot be determined according to the provisions of Article 510 of the Civil Code, the following provisions shall apply: if the method of performance is unclear, it shall be performed in a way conducive to achieving the purpose of the contract. According to the contract, the analysis is as follows: (1) If it is a definite time to start the machine on September 20, 2021, according to the contract, the first fund of Party A should be paid before September 20, 2021, the second fund should be paid before September 15, 2021, which is obviously illogical and not true. (B) The significance of fulfilling the obligation to pay the investment funds is to provide production funds for the play. When the contract was signed, the drama didn’t start shooting. The purpose of A’s investment in B was to raise funds for the drama, and the purpose of B’s investment was to provide shooting funds for the drama, complete the shooting and production of the TV series, and obtain income through distribution. Judging from the signing time of the contract and the agreement on the start-up time, the purpose of B’s investment fund is the shooting and production of the play, and the investment fund is actually the production fee. Usually, the venture capitalist pays part of the investment money first,It is in line with the investment practice and the contractual purpose of all investors to turn on the computer after the party who performs the production task. Therefore, it is more reasonable to plan the startup time on September 20, 2021. (3) The signing of the contract is a fact that the parties can decide, but the starting of the TV series is an uncontrollable fact. Whether the TV series can be started is restricted by many factors, such as the availability of funds, the signing of the main creator, the participation of actors, etc., and there is some uncertainty, which belongs to the category of conditions. It can be expected and foreseen but cannot be determined. Even if the agreed time is fixed, the parties should judge in advance that it cannot be achieved. Based on the foregoing analysis, the contract involved in the case stipulates that Party B shall pay the first investment before September 20, 2021, and determine the starting time after receiving the payment, and Party B shall pay the second investment five days before starting.

To sum up, Party B’s first investment payment obligation comes first, and Party A’s startup obligation comes last. The order of the two obligations can be determined. B’s claim about exercising the right of defense of prior performance lacks factual basis and cannot be established. Its failure to fulfill its payment obligation as agreed constitutes a breach of contract.

The method of performance is the specific method that the debtor should take to perform his debts. The mode of performance is generally determined by the nature and content of the contract. When the mode of performance cannot be determined, it should be performed in a way that is conducive to achieving the purpose of the contract. The purpose of the contract should be determined according to the original purpose of the debt corresponding to the debt and the interests expected by the creditor through the debt.

Reference case:

Beijing Intellectual Property Court (2018) No.560 Civil Judgment of J.73 Minzhong

Affected by the COVID-19 epidemic, colleges and universities all over the country started online teaching on the original starting date (around February 17th). As of March 14th, online teaching in most colleges and universities has been going on for about four weeks, and the online teaching has entered a relatively stable state. At this time, it is urgent to investigate and study the effect of online teaching in colleges and universities nationwide, so as to provide reference for college teachers to improve the effect of online teaching. Therefore, the research group of Hebei University conducted a survey on the effect of online teaching during the epidemic period for college students nationwide from March 14th to March 17th, 2020.

A total of 5094 valid samples were obtained in this survey. The respondents came from 113 universities in China, covering 13 disciplines, from the first year of university to the third year of graduate students, of which 34.9% were men and 65.1% were women.

According to the survey data, 69.16% of the students spend more than 4 hours in online teaching every day, among which 21.83% have more than 6 hours in online courses every day, and only 30.84% have less than 4 hours in online courses every day. It can be seen that the online learning task of college students is heavier.

First, the overall evaluation of online teaching-"It is not easy to say that I love you!"

Then, compared with the traditional classroom, what is the overall evaluation of students on the simple online teaching?

　Figure 1 Percentage of overall evaluation of online teaching (unit:%)

1. Network teaching has no obvious effect on highlighting students’ dominant position.

Compared with traditional classroom teaching, online teaching highlights students’ dominant position. Do you agree with this statement? In the answer to this question, 45.23% of the students said "agree or strongly agree", 41.58% said "average" and 13.19% said "disagree or strongly disagree".

2. Online teaching has improved students’ self-study ability.

Compared with traditional classroom teaching, online learning has enhanced my self-study ability. Do you agree with this statement? According to the statistics of the answer to this question, 59.71% of the students chose "agree or strongly agree".

3. Web-based teaching has not well mobilized the enthusiasm of college students for class participation.

Compared with traditional classroom teaching, students are more enthusiastic about participating in online classroom. Do you agree with this statement? According to the statistics of the answer to this question, only 38.10% of college students said "agree or strongly agree" and as many as 22.58% said "disagree or strongly disagree".

4. The effect of online teaching in improving the interaction between teachers and students is average.

Compared with traditional classroom teaching, there is more interaction between teachers and students in online teaching. Do you agree with this statement? According to the statistics of the answer to this question, only 34.58% of college students said "agree or strongly agree" and as many as 19.55% said "disagree or strongly disagree".

5. The learning efficiency of students in online classroom teaching mode is not as good as that in traditional classroom.

Compared with traditional classroom teaching, online learning improves learning efficiency. Do you agree with this statement? According to the survey of this issue, as many as 29.78% of the students said "disagree or disagree very much", and only 29.78% said "agree or disagree very much".

Second, the choice of teaching methods after the epidemic-"still reluctant to part with you!"

Fig. 2 The situation of students’ choice of teaching methods after the epidemic.

The data shows that the teaching method of "traditional classroom teaching is the main method, supplemented by network teaching" has become the first choice for college students after the epidemic. This shows that the position of traditional classroom teaching cannot be replaced, but simple traditional classroom teaching and simple network teaching are not the first choice of students. On the contrary, the teaching method of "traditional classroom teaching is the main one, supplemented by network teaching" has become the first choice of college students. This requires that colleges and universities in China should seize the opportunity of implementing large-scale network teaching brought by the epidemic and vigorously develop network teaching in conjunction with traditional classroom teaching methods in the reform of teaching methods after the epidemic.

Third, the evaluation and analysis of the teaching effect of specific courses-"Old wine in new bottles, both are important"

We ask students to choose the specific course that they think is the best or the worst this semester to evaluate and answer the specific situation of this course.

1. Students have a high evaluation of the selected courses.

Among the scores of the selected courses, 74.07% students scored above 80, 18.59% students scored 60-80, and only 7.34% students scored below 60. It can be seen that students have a high evaluation of the effect of the selected courses.

Table 1 Distribution of College Students’ Evaluation of Specific Courses

2. The teaching effect of specialized courses is better than that of public courses, the teaching effect is better in the morning, and the network teaching effect of small-scale classes is better.

Table 2 Percentage of grading categories with different course nature, class time and class size (unit:%)

The results of data analysis show that there are significant differences in the teaching effect of different courses, different class periods and different class sizes. The teaching effect of specialized courses is better than that of public courses, the teaching effect of morning classes is better, and the network teaching effect of small-scale classes is better.

3. The teaching effect of live video is obviously better than other methods.

Table 3 Percentage distribution of teaching effect scoring categories by teaching form (unit:%)

The data shows that the teaching effect of live video is better than other forms, which also shows that "seeing is believing". Although students study at home, they are still eager for "face-to-face" real-time classroom form.

4. Courses with better image and sound transmission effect have better teaching effect.

Table 4 Percentage of course scores with different image effects and sound effects (unit:%)

The biggest feature of network teaching is that it is subject to the network transmission situation. The results in Table 4 show that different network conditions and sound transmission effects will bring different teaching effects, and the evaluation of teaching effects with good network conditions and sound transmission conditions is also better.

5. Electronic textbooks and supplementary materials are provided, and the teaching effect is better.

Table 5 The provision of all kinds of course resources and the scoring group of course teaching effect

During the epidemic period, students can’t go to school to get paper-based course materials such as textbooks and teaching AIDS, so whether online courses provide rich electronic course resources has become one of the factors that affect the teaching effect.

6. Online check-in and preview tasks are arranged in advance, and the online teaching effect is better.

Table 6 Pre-class process and course teaching effect score grouping

The results in Table 6 show that the pre-class task arrangement and electronic sign-in of online courses are also factors that affect the teaching effect of the course.

7. The course of using electronic blackboard books has a good teaching effect.

Table 7 Percentage distribution of teaching effect scoring categories by whether there are electronic blackboard books (unit:%)

Although the fluency and effect of online teaching electronic blackboard can’t be compared with the physical blackboard, the data show that the teaching effect of the course using electronic blackboard in the course is obviously better.

8. The higher the number of teacher-student interactions and the number of students who speak, the better the classroom effect.　

Table 8 Teaching effect evaluation groups of courses with different times of teacher-student interaction and number of students who speak (unit:%)

Classroom interaction is an important link and means to improve students’ participation and enthusiasm in class, which is also fully applicable to online teaching.

9. The course of homework and answering questions in time after class is arranged, and the teaching effect is good.

Table 9 After-class links and teaching effects

Paying attention to after-class links can effectively improve the teaching effect of the course, which is also fully applicable to online teaching.

10. Courses that can be played back have better teaching effect.

Table 10 Percentage distribution of teaching effect scoring categories by whether courses can be replayed (unit:%)

Online courses can be recorded and replayed conditionally, and the teaching effect of courses with replay is better, which requires teachers to make full use of the advantages and specialties of online teaching.

To sum up, the factors that affect the teaching effect of online courses are not only the traditional teaching factors such as preparation of teaching resources before class, interaction in class, homework and counseling and answering questions after class, but also the specific class form and the transmission effect of images and sounds. That is to say, online teaching only changes the teaching way and carrier, and its connotation has not changed except choosing the appropriate class form and smooth network guarantee, which depends on the energy input of teachers in the teaching of this course. It is called "new bottles and old bottles"

Thanks: The epidemic is dissipating, and spring is just around the corner. Thanks to the students from all corners of the country, and thank you for your sincere answers. Once again, I wish every one of you.
