Since 1976, he began to study high critical temperature superconductors, and his name has always been closely related to superconductivity for half a century.

　　As one of the pioneers who started the research of high-temperature superconductivity in China, he first proposed to explore high-temperature superconductors in China, and first proposed to set up a national superconducting laboratory … … It has made indelible contributions to China’s superconducting development from starting, catching up and being among the forefront of the world when it is 50 years behind.

　　In the history of superconductivity research for more than a hundred years, there have been two major breakthroughs in high-temperature superconductivity. He and his collaborators have made important achievements, namely, independently discovering high-temperature superconductors in liquid nitrogen temperature region and discovering a series of iron-based high-temperature superconductors above 50K and creating a record of 55 K.

　　Today, science and technology have a profound impact on the country’s future and destiny. In the field of high-temperature superconductivity, he and his team are constantly attracting groups of young people and pushing China’s high-temperature superconductivity research to the forefront of the world.

　　He said, "The core science and technology can only be done by ourselves. It is necessary to combine personal interests with the destiny of the country, cooperate in tackling key problems, and serve the country. "

　　He said, "I would like to be a paving stone and let young friends make great achievements."

　　He is the winner of the highest national science and technology award in China in 2016, academician of China Academy of Sciences and physicist Zhao Zhongxian.

　　Sidenote 1: When an old superconducting expert meets an old director of the compilation bureau.

　　There are four old people among the guests who participated in the recording of "Example" this time. Apart from the special guest Mr. Niu Benlao and a veteran member of the National Survey Team, Mr. Yu Qiqing, who was the first to take part in the Everest survey in China, he is the former director of the Central Compilation Bureau, Mr. Song Shusheng, and academician Zhao Zhongxian, a superconducting expert.

　　During the filming, Academician Zhao Zhongxian and Mr. Song Shusheng sat together. One of them leaned back thoughtfully, and the other sat upright and had a straight body. I thought that two doyen in different fields would care for each other and sit together as a pair of quiet handsome men, but there was a special dialogue:

　　"I have read Anti-Turin Theory." Academician Zhao said.

　　"This book is good, it expounds the three components of Marxism, and it is also relatively easy to read … …” Mr. Song Lao also turned around and began to communicate seriously.

　　Compared with HTS, a high-cold scientific research topic, the old academician Zhao Zhongxian himself gives people a much more vivid feeling.

　　He is humorous and honest and frank. From time to time, he uses his loud voice to open the "Tucao" mode, which causes people next to him to laugh. He has a wide range of daily hobbies, and he tries skiing and drifting. Literature, photography, cultural relics in museums and good music in China and the West are all his interests. His heart is firm and soft, with the rigor, strictness and seriousness of scientists, and he always thinks about students and the life and future development of young people.

　　Under his "independent" face, there is warmth, hope, swallows whispering, and flowers blooming from tree to tree.

　　Sidenote 2: "Scientific research is like playing mahjong"

　　When the program was recorded, Academician Zhao Zhongxian was asked: "You have done one thing all your life, and it is something that 99% people in the world don’t understand. How did you persist? " The old gentleman’s spit mode was turned on.

　　"I think many people don’t understand the fun of scientific research, saying that scientific research is a bench and asking me why I can persist for decades. If you like playing mahjong, do you think you can’t stick to it? " The old man said.

　　"Scientific research will encounter such difficulties, but just like people playing mahjong, as long as they are interested, they still want to play if they fail, not to mention that we often draw cards, small and big!"

　　In his mind, the "bench" of scientific research is not always cold. Despite many difficulties, in the process of research, the more you do, the more interested you are. Interest is very important. You are addicted and very willing to do it. At the same time, it is also an encouragement to make new progress in our work. Insisting on doing something has a sublimation of understanding on the basis of long-term accumulation.

　　In a speech, he mentioned how he became interested in science: in 1956, the state proposed "marching into science." As an imaginative and energetic middle school student, he participated in extracurricular activities of the school physics group and read popular science magazines, which led him to like science. He said: Many years later, I gradually realized that understanding science is a kind of enjoyment, which can gain new knowledge, arouse curiosity and enhance interest.

　　He was admitted to China University of Science and Technology in 1959. He said that at that time, many students were willing to study science and engineering, which was the call of the state and very fashionable. Popular majors include atomic bombs, semiconductors, etc. "I remember that the cover of the admissions brochure of the University of Science and Technology of China is the rocket. I think it is this that attracted many students, including me, to apply for China University of Science and Technology. It should be said that the call of the country made many people in our generation choose science and technology. "

　　He said that it is the best choice to combine personal interests with livelihood, and he happened to be very lucky.

　　Sidenote 3: I think it is very important to settle down and do things.

　　In the process of chatting with Mr. Niu Ben, when he mentioned some "short and fast" phenomena in the film industry, Mr. Zhao Zhongxian’s tucao mode was opened again:

　　Now there are so many scientific and technical personnel and teams all over the country. I think it takes a person or a team ten years, or twenty years to solve an important scientific problem or a core technical problem. Does that add up?

　　He said, don’t be eager for quick success, set a long-term goal. "Now these young people have a good foundation, because their education is very complete, their equipment is world-class and their funds are sufficient. I think the current conditions are very good, and the key is to settle down and do things. "

　　He believes that "scientific research is a natural and rising process. You have a group of people who have found the right direction and made unremitting efforts in a down-to-earth manner, and will always make discoveries that are beneficial to the progress of human civilization. " As long as all of us can settle down and concentrate on our work, instead of catching up with the "trend" to do things of the same nature, short-term and quick success, our country’s science and technology will develop faster and better.

　　He said, "I have only done one thing in my life, that is, exploring superconductors and conducting research on superconducting mechanisms. If everyone in our society persists in doing one thing, many problems can be solved. "

　　Sidenote 4: "Academician Zhao speaks the scientific research party class very well."

　　During a chat, Academician Zhao Zhongxian chatted, "I have both Chinese and English versions of The Supreme Leader’s Talks on Governing the Country, and some places in the English version are more clear than the Chinese version."

　　Teacher Dong, the assistant, is sitting on the side. "Academician Zhao speaks the scientific research party class very well."

　　On July 19th, at the China Academy of Sciences’ theme activity of "Patriotism and Dedication, Being the Pioneer of the Times", Academician Zhao Zhongxian was invited to give a special party class to the delegates.

　　He talked about the patriotism, dedication, scholarship and self-cultivation of the older generation of scientists, and that after entering China University of Science and Technology, he was inspired by the knowledge and spirit of the older generation, and gradually changed his love for science when he was young into a sense of responsibility and mission in scientific research.

　　He said that the older generation of scientists taught not only knowledge, but also spirit. In his study and practice, he constantly understood the essence of these famous predecessors’ scholarship, and gradually realized that scientific research needs to take root, and long-term persistence and accumulation will be sublimated in understanding, so as to seize opportunities and accumulate wealth.

　　He said that his 40-year persistence benefited from the stable environment, and he grew up under the inspiration of the spirit of the old Red Army and the patriotic dedication of the older generation of scientists. The most comforting thing is "I gave".

　　He hopes that young friends can settle down and concentrate on their work. "One generation does the work of another generation, and several generations of teachers and students cultivate it to realize the rooting of Chinese science." He also believes that they have the ambition and ability to contribute to building a world-class science and technology power and the progress of human civilization.

　　Sidenote 5: Why can you do one thing all your life?

　　"I have faith and am interested in science."

　　During my brief contact with Academician Zhao Zhongxian, the words "faith" and "interest" impressed me the most. These two words have accompanied his life’s choices and supported his scientific research career for decades.

　　In 1956, the state proposed "marching into science". As an imaginative and energetic middle school student, he took part in extracurricular activities of the school physics group, read popular science magazines, and gradually became fond of science.

　　In 1959, he was admitted to China University of Science and Technology, and listened to the lectures and reports of famous teachers and the relationship between science and technology and the fate of the country. He began to feel that he was not only fond of science, but also had a sense of responsibility and mission.

　　In 1972, China Academy of Sciences won more than 20 places to study abroad, and he was selected to go to Cambridge University in England for further study after applying for superconductivity. He enjoys the experimental work of "nine to ten" and is always full of passion. Seeing the gap in contact with international counterparts, he began to move towards the field of high temperature superconductivity.

　　China, who is in a great hurry, returned to China to lead his team to build their own experimental equipment. The conditions were so hard that he beat mice under the covers. He was still optimistic that his relative disadvantage was not so great. "Compared with other scientific research, the exploration of superconducting materials does not need particularly advanced and complicated instruments. I am willing to make full use of the existing conditions to carry out a project."

　　After decades of high-temperature superconducting research, he felt the regret that he was beaten to the top by one step, and he also experienced the joy of seizing the opportunity when the international competition was the fiercest. I have experienced the frenzied scene of the "Rock Music Festival in Physics" which lasted for more than 7 hours, and I have also been under great pressure to be questioned because of the many achievements of raw materials and impurities used in experimental samples. Or sit on the bench day after day, or add honor to your success. Between ups and downs, his interest remains, his faith remains, and his "initial heart" has never changed.

　　For half a century, he has always been interested in and curious about science as a teenager. "Doing scientific research is like playing mahjong," he said. In the research process, despite many difficulties and addiction, the more you do it, the more interested you are and the more willing you are to do it. Just like mahjong clubs and cards, every progress in work is also encouragement. "

　　Faith is more like a flower in his heart when it is chilly in spring. He said that insisting on doing something will lead to the sublimation of understanding on the basis of long-term accumulation. In day-to-day scientific research, he sees the charming charm of superconductivity, firmly believes that there will be a breakthrough in superconductivity, and firmly believes that his research has great scientific significance and application value, and can contribute to this country, nation and human civilization.

　　He said that a country’s scientific and technological strength can’t be bought with money, and it can only be based on itself. It is necessary to combine personal interests with the destiny of the country, tackle the problem with teeth, and serve the country with knowledge.

　　China Meteorological News correspondent Liu Shouyu reporter Deng Minjia

　　In the early morning of July 7, there was a rainstorm in Fuliang County, Jingdezhen City, Jiangxi Province. As of 20: 00 on the 7th, there was heavy rain in the county, and the precipitation in the upper reaches of Fuliang Town passed through Gongqiao Town, Jiangcun Township and other places exceeded 250 mm, and the water level of Changjiang River soared.

　　Will such heavy rainfall affect the safety of people in low-lying areas? Do you want to transfer people? The county government and township leaders are worried.

　　At 14: 56 on the 7th, the meteorological bureau of Fuliang County released the first local rainstorm red warning signal this year. The release of this rainstorm red warning triggered the whole network release mechanism of the county red warning. At 15: 44, all mobile phone users in the county received the red warning message of rainstorm.

　　At the same time, the meteorological and hydrological departments, after joint consultation, judged that the Changjiang River would have a flood exceeding the warning level of 4 meters, which immediately blew the whistle of the county’s large-scale emergency transfer of people in low-lying areas.

　　In the Old Town Village of Fuliang Town, Yu Shunfa, a meteorological information officer, immediately reported to the two committees of the village after receiving the rainstorm red warning signal. The two committees of the village organized village cadres, backbone militia and party member to help the masses transfer. As of 20: 00 that night, there were 320 households with 1,351 people transferred from Old Town Village.

　　"Thank you so much!" On July 8, Dengsheng Wang, a villager who moved to safety before the flood, took Yu Shunfa’s hand and thanked him again and again.

　　At 3 am on the 8th, the flood peak water level of Changjiang River reached 33.14 meters, exceeding the warning water level by 4.64 meters, and the tributaries such as Jianxi River and Xiaobeigang experienced super-historical floods. When the flood peak reached Fuliang Town, the low-lying area was covered with Wang Yang. After dawn, Dengsheng Wang rushed to the hillside near his home and saw that the second floor of his home had been soaked in the flood.

　　During the rainstorm, Fuliang Town and nearly 20 townships including Jiangcun Township, Wanggang Township, Jinggongqiao Town and Legong Township urgently organized personnel transfer. As of 0: 00 on the 8th, 495 houses collapsed and damaged in Fuliang County due to the disaster, and 23,136 people were transferred urgently. Due to timely warning and effective prevention, there were no casualties.

　 　 [XCAR Deep Observation Original]

　 　 Foreword:In the previous article, we talked about the topic of "China brand collective counterattack", but mainly talked about the "big guy" in China brand, including the "four big and four small" in state-owned car companies and private car companies in the first-line camp. This issue will continue this topic, but the goal has been changed from "big guy" to "small guy". The so-called rising tide lifts all boats, the continuous expansion of China automobile market, and the improvement of the overall technical level will also bring opportunities to those "small guy" automobile enterprises in China market. "Small boats are easy to turn around". If they respond quickly enough and find the right development direction, these "small heads" can also overtake in corners. Inadvertently, you will suddenly find that their growth rate is much faster than you think. Let’s take a look at several representative car companies.

　 　 ● Zotye automobile

　　　　Speaking of Zotye, there seems to be no sense of existence for a long time. The initial impression is that SUV model that looks like Toyota Terui, and the car name is still changing from 2008 to 5008, but the model has not changed. The first judgment is that this car company has no strength of independent technology development. In addition, it seems that there is not much ambition after a long period of obscurity. In fact, among private car companies, Zotye started not too late, and it was almost the same as BYD’s entry into the automobile field, both in 2003. Like BYD, Zotye had a long history before it entered the automobile field, but its old business was not electronics, but hardware.

　　　　Zotye Automobile’s predecessor was the Great Wall Hardware Machinery Factory, which was established in 1994 and located in Yongkang, Zhejiang Province, where the private economy was very developed. Since then, the Great Wall Hardware Machinery Factory has been renamed Tieniu Group, which has experienced rapid growth and subsequent industrial integration. In 2003, Tieniu Group entered the automobile field after acquiring the shares of Jinma, which produces key automobile parts, and established Zotye Holdings, with Wu Jianzhong as the chairman.

　 　　By chance, Zotye Automobile bought a Toyota TERIOS production line sold by a Taiwan Province automobile company due to financial problems, and gained the capacity of vehicle production. But since then, it has faced the same problems as all private cars — — The qualification of vehicle production was initially achieved through cooperation with Chengdu Xindadi Automobile, but after all, it was an expedient measure. In March 2007, Tieniu Group broke through many obstacles and successfully acquired 70% of the shares of Jiangnan Automobile Manufacturing Co., Ltd., thus taking Jiangnan Alto to its subsidiary and "buying" a car "birth certificate" of its own.

　　　　The bumpy road is somewhat similar to the initial stage of Geely and BYD, but the process is more tortuous, which also honed the indomitable will of Zotye Automobile. In the first five years of its establishment, Zotye had only one product such as 5008. The product line was thin and the lack of independent development capability was the biggest bottleneck. Since then, Zotye Auto has thought of introducing mature overseas technology platforms. In 2008, Zotye bought some relatively old technology platforms and production lines of Fiat Auto, such as the early wide-body MPV Dream Deborah, and it was reported that Zotye bought out the four production platforms of M/P/D/L from Fiat, and Palio, which was once produced in Nanjing Fiat, will also be produced in Zotye Factory.

　　　　After purchasing the technology platform from Fiat, Zotye’s product line finally expanded, and since then, it has also launched Langlang and Langjun based on Fiat Palio and Siena. Although it is an old platform, Zotye has carried out independent design and transformation, which is also the consistent practice of Zotye to launch new cars since then.

　 　 With the technical support of Fiat, at the Shanghai Auto Show in 2011, Zotye’s product line suddenly broke out, and a large number of previously unavailable models appeared on the booth, covering many fields such as mini-cars, compact cars and SUVs, and adopted a brand-new letter+number naming method.

　 　 The imitation traces of Lang Lang and Lang Jun introduced by Zotye in the early days are very obvious, and the independent design is not mature enough, with a strong "cottage" atmosphere. In addition, Zotye is not good at marketing and its market performance is relatively general. The real turning point is the launch of Zotye Z300 and the joining of Xia Zhibing, former general manager of BYD in 2012.

　　　　Zotye Z300 has greatly surpassed Zotye’s previous products in terms of design and interior. Its appearance is fashionable and generous, and the interior is also very advanced. Coupled with the large body size and low price, the outstanding products offset the lack of brand power and achieved good sales results. In addition, after Xia Zhibing became the president of Zotye Automobile, he was fully responsible for the management of production, technology and sales. Zotye’s product development and positioning, as well as subsequent marketing, have all reached a higher level, and Zotye’s development has also entered a fast track.

　　　　In 2013, Zotye Automobile sold more than 134,000 vehicles, an increase of more than 40% compared with 2012. At the end of 2013, another heavyweight model of Zotye, Zotye T600, went on the market. This model, which looks like "Volkswagen Touareg", is quite controversial. However, for a car company like Zotye, which originally lacked brand power, barbaric growth is sometimes an essential stage. The market finally gave the answer. The monthly sales of Zotye T600 is about 5,000, and it has entered the mainstream camp of China brand SUVs.

　　　　In 2014, Zotye introduced the Z500, which has got rid of the shadow of imitation in appearance, and the design can be said to be outstanding, fashionable and sporty, and equipped with a 1.5T engine to match the CVT gearbox. This model has reached the middle and upper reaches of China brand in all aspects, which makes people sit up and take notice.

　　　　At this year’s Shanghai Auto Show, Zotye once again brought surprises, and launched a brand-new medium and large-sized car Z700. This flagship model is somewhat Audi A6 in design, but it is not a naked imitation, but has added many independent design elements. And the interior technology and configuration have a good performance, and the 1.8T and 2.0T power is also a selling point. In addition, another urban SUV model, Damai X5, is also very interesting, with mature design and an estimated price of 80,000 yuan.

　　　　It is worth mentioning that Zotye has also made great achievements in the field of new energy. In addition to the previously launched Zhidou electric vehicle, the auto show also launched a brand-new Zotye E200/ sesame E30 electric vehicle, which will be launched in September this year. The design is very interesting and can meet the daily needs of urban transportation. Zotye entered the new energy market very early, and electric taxis have been piloted in Hangzhou for many years, which has accumulated a lot of experience and is also very prescient.

　　　　Zotye’s success lies in the successful grasp of the domestic market demand. For example, after having a mature technology platform, it puts more energy into improving the design level. It has to be said that the design level of Zotye’s new car has been in the middle and upper reaches of the China brand, leaving a good first impression on consumers. In addition, the body size is also very advantageous compared with competitors at the same level. Coupled with rich configuration and a price that is close to the people, the product’s competitiveness is excellent.

　　　　Some people may say that if it’s just beautiful in appearance but lacking in core competitiveness, isn’t it a vase? But the fact is, in this era of hard work, will you choose a car with excellent performance, but will it be ugly enough to affect your mood when you go out? Moreover, with the foundation of Fiat technology, Zotye’s core technology foundation is still good, and it is a bit wrong to call it a "vase"!

There are various detailed explanations about the personalized recommendation algorithm of Netease Cloud Music on the Internet, but the official has never appeared! In order to solve users’ curiosity about the algorithm behind the daily recommended song list, we broke into the product and technology department of Netease Cloud Music Headquarters, held technical experts hostage, and spit out all our doubts.

This article is transferred from: The Power of Machines | Utoda

Old irons, do you know what day it is today?

Knowing that we should say happy holidays, we can’t forget to wait for the singles assigned by the state in the cold kennel.(as if I wasn’t talking about myself).

This morning, when I found that the dog food scattered by my circle of friends had been enough for one year, I still turned on Netease Cloud Music, trying to find the same kind in the lively comment area: another group of single dog people.

Unexpectedly, in addition to a "special interview for the first year of singles", the first song recommended to me every day turned out to be:

The Best Day of My LifeBest day of my life.

……

Well, the lyrics "I won’t give up on myself, don’t wake me up, this is the best day of my life", which makes me seriously doubt that the personality recommendation of Netease Cloud Music has penetrated the normal life of all single dog users:

"Don’t always stay in the comment area, please find your own happiness before coming next year. Otherwise, as soon as the Year of the Dog is over, your title will become’ single pig’. "

Happy Valentine’s Day and Happy Year of the Dog.

On the Zhihu, two questions, "What is the song list recommendation algorithm of Netease Cloud Music" and "What’s good about Netease Cloud Music", occupy the third and eighth place in the hot topic of Netease Cloud Music respectively.

To a large extent, the first question has made the second question.

Perhaps Netease Cloud Music has a variety of reasons for its one-sided praise on Zhihu.Some people say that they have hired a large number of water forces. If so, it should be a heavy investment. I won’t tell you that the communities of the two platforms overlap greatly)However, the quality of the song list is hard, and the personality recommendation is relatively accurate compared with the domestic competing products, which is one of the key reasons for some users to develop into Netease Cloud Music diehard fans.

And, the first question can also explain why you will see a lot of comments such as "Japanese push first", "Japanese push second" and "Japanese push +FM simultaneous recommendation" in the comment area of many songs.

However, it is not very appropriate for some people to compare Netease Cloud Music to "a paradise for independent and minority music lovers". Re-exposing those songs that have been ignored by the public to your eyes is often the role of technology behind the scenes.

Just like you downloaded a song from Jay Chou today, will the system push you another popular song with a similar style in Jay Chou the next day, or push an unpopular song with a similar style, which will make you feel more novel?

There is some truth in this answer.

However, it is a bit surprising. Netease Cloud Music has never officially disclosed its recommendation algorithm and product application details. But this does not prevent the public from being interested in the process of integrating their technology and products.

Therefore, the algorithm model and AI application in Netease Cloud Music have basically been ripped apart by Zhihu users.

You can find a great answer and speculation in the Zhihu topic "What is the song list recommendation algorithm of Netease Cloud Music?"(The high praise answer in it is not too clear than the media reports, and it is easy to understand.).

The reason why we want to visit Xu Jia, a data mining engineer and product manager of Netease Cloud Music, is not so much to uncover the secret of the algorithm as to verify it before.(including on the Internet)All kinds of guesses, as well as help users answer the doubts arising from the use of Netease cloud music.

Basic algorithm: people are divided into groups

In fact, the personalized recommendation algorithm of Netease Cloud Music is similar to the basic recommendation algorithm applied in today’s headlines, station B and many O2O e-commerce platforms. This has been certified by the Xu family, which is the kind of basic algorithm we are familiar with:

This algorithm is attributed to the invention of Amazon engineers-if a customer buys this thing, he may also buy another thing.

Simply put,The prediction standard of this algorithm depends on the similar consumption patterns between people.For example, I like these two songs, and they are also in your song list, so there may be other songs I like in your song list.

The above statement is only easy to understand.In fact, collaborative filtering algorithms should be divided into two categories: user-based and project-based (single).

1. Based on users:I have a high similarity with Xiao Ming’s collection of songs, so on the basis of judging that our tastes are similar, I can recommend Xiao Ming the singles in my collection that she hasn’t collected.

2, based on the project (single):That is, the user’s preference for a song is used as a vector to calculate the similarity between singles. After comparing the similarity, we recommend a single to another user according to this user’s historical preference.

For example, Xiao Xin downloaded two singles, Courage and Little Love Song, while Xiao Yi downloaded Courage, Darkness and Little Love Song, while Xiao Yi downloaded Courage …

According to the historical preferences of these users, Netease Cloud Music can judge that Courage is similar to Little Love Song, and those who like Courage may also like Little Love Song, so they can recommend Little Love Song to Xiaoyi.

Image source: data mining workers

In short, if you still find it difficult to understand the algorithm of "collaborative filtering", you can just remember one word: people are divided into groups.

It’s a crooked building here: it is this recommendation model, which is essentially based on the similarity of users’ preferences, that invisibly makes users form a community of "chatting with each other" while listening to music.

Therefore, Shen Bowen did not regard "it may develop into the largest dating website in China in the future" as a nonsense joke. Instead, I think that this social trend based on music preferences is more reliable than the current dating platform:

Curiosity Daily has done a survey before. What are the main reference standards for human beings to find their soul mates? -it’s music taste.

"Birds of a feather flock together" under the neural network model

It can be seen that this recommendation algorithm is absolutely indispensable to the support of user historical data. Collaborative filtering algorithm is very powerful when the amount of data is huge and clean enough.

On the other hand, if I am a new user, or I use Netease Cloud Music very infrequently. In other words, in the case of scarce data, how can Netease Cloud Music know my taste?

This cold start problem means the inevitability of cross-use of different algorithm models. Perhaps the following second category of algorithms can eliminate this obstacle to some extent.

• Content-based recommendation algorithm.

This is a recommendation method that focuses on distinguishing the essence of single content, and it is regarded as "birds of a feather flock together".

Sander Dieleman, one of the founders of Spotify content recommendation model, a world-famous music streaming platform.(now a DeepMind research scientist)In a blog post titled "The Application of Convolutional Neural Network in Music Recommendation", I specifically explained the errors when using a single collaborative filtering algorithm:

1. Because this algorithm not only includes the information of users and consumption patterns,There is no information about the recommended single itself. Therefore, popular music is easier to be recommended than unpopular music because the former has more data. And this kind of recommendation is often hard to surprise.

2. Based on collaborative filtering of items (single songs),There is also a problem, that is, the content heterogeneity under similar usage patterns.

For example, if you listen to all the songs in a new album, but except the title song, other episodes, covers and remixes may not be typical works of singers, then collaborative filtering will be biased because of these "noises" at this time.

of course，Its biggest problem is that "without data, everything is invalid".

Therefore, the content-based recommendation algorithm is more like a supplement to the above shortcomings of collaborative filtering algorithm-if there is not a lot of user data, or if we want to listen to unpopular songs, we can only find the answer from the music itself.

Two experts, Xu Jia and Shen Bowen, made it clear that Netease Cloud Music adopted a complex content-based algorithm to solve these problems. But unfortunately, the two did not explain the specific details too much.

Therefore,According to our guess, they should use the same method as streaming media platforms such as Spotify and Youtube-using deep learning to build audio-based recommendation models..

First of all, if you want to compare the content differences between singles, there are too many dimensions, such as artist and album information, lyrics, melody and rhythm of music itself, boasting in the comment area, VIP downloading songs, paying or not, and so on.

As you can imagine, this is a huge amount of calculation. But calculating the total amount of violence is a method …

Therefore, so many features should be mapped into the low-dimensional hidden variable space by feature embedding and dimensionality reduction methods.(Like the picture below).

It is conceivable that in this space, each song can have a coordinate, and the coordinate value is multiple coded information including audio characteristics and user preferences.

Then, if we directly predict the exact position of a song in this low-dimensional space, it will also clarify the representation of this song.(including user preference information).

In this way, it can be recommended to the right audience without historical usage data.

Therefore, it is a way that many streaming media are taking to master the hidden characteristics mapped from a large number of song data sources and user behavior data, and then establish a neural network prediction model based on audio characteristics and train the network with short audio clips. (The specific method can be to look through Sander Dieleman’s paper. If you know this, tell us a lesson! )

Of course, in the process of training the network, engineers will still pass the "discard"（Dropout）And other methods to reduce the standard deviation between the hidden representation of filtering model and audio prediction.(Don’t let the data set be too discrete)And this is mainly to reduce the influence of song popularity on the recommendation system.

That’s right, that’s why you can receive more minority song recommendations.

Of course, any of the above algorithms will actually be based on a certain "similarity".

For example, Netease Cloud Music also applies the machine learning ranking model, which is still based on user behavior data and similarity.(It is also a very common model).

Reflected in the application, in popular terms, the first song in your "Daily Recommended" song list is usually the one that the system thinks matches your preferences the most. "Many people often shout’ Day Push First’ in the comment area, and its significance is still quite great."

In Zhihu, there is a recommendation model "Potential Factor Matrix" mentioned by Big V, but Xu Jiaze thinks it is out of date, and few people use it now.

Calculation method-how do we calculate the similarity of our song list?

According to the Xu family, Netease Cloud Music mainly uses two measurement methods:

Euclidean distance and cosine similarity.

The blog of a technical expert in CDSN has explained the difference between them very clearly.(below)：

From the CDSN technology blog named Ying.

The former is regarded as two points in the coordinate system to calculate the distance between the two points.

For example, when data A and B in the above figure are regarded as points in the coordinate diagram, their similarity is the absolute distance dist between two points.(A,B).

The latter is regarded as two vectors in the coordinate system to calculate the included angle between the two vectors.

For example, cosθ in the figure, the smaller the included angle, the higher the similarity.

You will find that, still on this picture, if the position of B remains unchanged and the position of point A continues to extend in the opposite direction of the line from A to the origin, the cosine angle between A and B will remain unchanged forever, but the absolute distance between the two points has changed.

This difference makes them need to be used in different data analysis models.

Xu explained that Euclidean distance, which can highlight the absolute difference of numerical values, is often used in calculating the similarity of songs themselves.

For example, 10,000 people like A songs and 20,000 people like B songs. Because the sample size is large enough, all users’ preferences for songs can be regarded as the same intensity, then the European distance can be directly used to calculate.

Under the European distance, users’ preferences for songs can all be considered as the same score, which can simplify the calculation of song similarity.

The cosine similarity is more about distinguishing differences from the user’s preference direction.

For example, Netease Cloud Music can use this method to rate content through users.(There are different scoring weights such as download, collection, search and uninterested)To distinguish the similarity of users’ interests.

In short, combining the above algorithms and calculation methods, Netease Cloud Music’s personality recommendation has a good reputation among the public.

But this kind of "not bad", if it can be achieved only by technology, I am afraid that Amazon’s business in China will not be so bad(I’m actually voicing its interface).

Frankly speaking, even the best algorithm has its shortcomings.

For all music products, the score of user experience is composed of editing and project collaboration, interface design preferences, music copyright richness, music preference prediction, technical ability and problem feedback speed.

This is why some people are crazy about calling for the recommended song list of Netease Cloud Music, and many people say that "people who listen to miscellaneous songs may be really tired of using Netease Cloud Music".

For example, you are a loyal fan of European and American music circles, but you have downloaded a Chinese song occasionally recently.

Then I can be sure that there will be a Chinese song in your recommended song list the next day. Next, I can only be "uninterested" in the Chinese songs that appear in the song list.

The recommendation algorithm sets the weight based on different users’ behaviors, with "download" being the highest, followed by collection, search and sharing. In addition, you can also click "not interested", which may avoid such songs.

In addition to algorithm recommendation, to a great extent, a streaming media platform will also assume the responsibility of manual filtering, establish manual rules from the perspective of products and operations, and filter out unqualified options.

Shen Bowen told us that they don’t just rely on the algorithm, but hope to compensate some shortcomings of the algorithm through some artificial power.

Therefore, in addition to a separate algorithm team, Netease Cloud Music also has a strong editorial team.

On the one hand,They help to do a layer of screening on the recommended content at the beginning, find out those high-quality content, and ensure the health of the whole recommendation library.

On the other hand,They also need to solve some convergence problems of the algorithm.

"Because if we rely solely on algorithm recommendation, we may be slow to respond to some new content, and we will also use some manual editing methods. To find out some content that we may think is very high quality, and then recommend it to everyone, "Shen Bowen said.

In addition, even if the customer service system relies on AI technology to a certain extent, the "artificial feedback group" composed of Netease Cloud Music customer service department and technical department is an important reason for users to have a good impression on Netease Cloud Music.

Many "second-back" technical solutions have also been dubbed by users as "the original Xiaobian of Netease Cloud Music is really alive".

In the early stage of platform development, when the data volume can’t meet the requirement of establishing recommendation algorithm model, as an Internet author named Shaq in Zhihu described:

The reason why you can get the high-force recommendation is probably that it first came from a song list recommended by a professional editor named "High-force Small Fresh".

They effectively guided users with similar interests to discover these music. Most people who have similar tastes with you have heard them and felt good. After fancy’s algorithm, they "precipitated" and "fermented", and then produced a good similarity, thus generating such an excellent recommendation and pushing it to you.

Finally, everyone was "amazing" and more new users joined, Perfect.

In the automobile circle, Li Xiang and Li Bin, the old rivals, are often compared together. Before building a car, both of them came from automobile content, and founded car home and Easy Car Network respectively.

The traces of the founders of these two websites located in the downstream of the automobile industry chain are fading away, but the competition between the two sides has not cooled down. As the former overlord of car Internet platform, car home has been completely overtaken by Easy Car in terms of monthly users and new users.

Behind car home, Easy Car is supported by Tencent resources. In addition, the car-savvy emperor who is backed by ByteDance has also become a key player.

Car home, facing the squeeze of "Easy Car" and "Know Car Emperor", saw its revenue and profit drop in the second quarter, and its main business shrank sharply, which caused the market to worry about its declining performance. Since July, several investment banks have downgraded car home.

In addition, since the company was listed on the Hong Kong stock market in March this year, its share price has fallen by more than 50%, and its market value of nearly HK$ 50 billion has evaporated.

Why is car home here?

The decline in performance was superimposed by changes in executives, and many investment banks downgraded their ratings.

The second listing in Hong Kong did not make car home’s development more smooth.

On March 15th this year, car home was listed on the Hong Kong Stock Exchange, with an offering price of HK$ 176.3 per share and a net fundraising of over HK$ 3.4 billion.

The latest second quarterly report shows that the company’s net profit attributable to ordinary shareholders is 747 million yuan, down 9.43% year-on-year; Operating income was 1.938 billion yuan, down 16.22% year-on-year.

Among them, the largest business media service sector, which is the foundation of the company, fell by over 30% year-on-year, and its revenue scale was 330 million yuan less than that of the same period last year; The management explained that due to the global chip shortage, car companies adjusted their advertising budgets accordingly, resulting in a decline in the average income contributed by advertisers per car company.

Clue service is the second largest business in car home, which is mainly aimed at dealers to obtain customers. The quality of sales leads is high, and dealers have a strong willingness to spend money on advertising. Clue service is a key indicator to measure platform marketing and commercial value. In the second quarter, car home’s income from this business also declined a lot.

In terms of new business, car home’s online marketing and other income during the reporting period was 594 million yuan, up 10.0% year-on-year, which was the only part of the company’s three-part business.

Prior to the disclosure of interim results, CFO changes had just occurred in car home. On July 2, Zou Jun, the company’s chief financial officer, said that he resigned as CFO for personal reasons.

Before Zou Jun left the company, there had been many high-level adjustment events. In January, Lu Min, who had been at the helm of the automobile home for about four years, was "retired" from the position of chairman and CEO, and Longquan, an executive of Ping An Department, took over. In May, co-president Zhang Jingyu resigned for personal reasons.

Since July, several investment banks have downgraded car home.

Eddy Wang, an analyst at Morgan Stanley, downgraded car home’s rating from high to even, and lowered its target price from $106 to $50.

According to the report, "We expect car home’s core business income to achieve a low single-digit percentage growth, mainly due to intensified competition from major competitors such as Know Car Emperor and Easy Car. The profit forecasts for 2022 and 2023 are lowered by 12% and 19% respectively to reflect the lower income growth rate and gross profit forecast. "

The agency also said that it is expected that the departure of senior managers in the past two months will bring more uncertainty to the company’s strategy.

According to the analysis of Bank of America, car home has changed from a solid online vertical market leader to an increasingly weak market participant affected by the headwind and competition of the automobile industry.

The bank pointed out that the periodicity of the automobile market may mean a long-term headwind, and the competition in automobile consumption is intensifying, which will have a negative impact on car home. Therefore, car home was downgraded to "underperform the broader market" with a target price of $46, which was almost the same as the $45.34 before the US stock market opened on September 13th.

At the same time, Citigroup downgraded its rating to neutral, believing that there is still a big gap between car home and its competitors in terms of user scale, and that more intense competition, "lower car budget" and strategic change are all factors that affect car home’s rating.

Industry "boss" position is not guaranteed

At present, in addition to car home, there are "Tencent" Easy Car and ByteDance’s Car Master.

Easy Car was founded in 2000 by Li Bin, chairman of Weilai, and was once the "first stock of China automobile industry listed in the United States". After several years of losses, it was privatized and delisted in November 2020, and the buyer consortium headed by Tencent acquired and became the controlling shareholder for $1.1 billion.

At the same time, car home’s share price kept climbing, and by the end of January this year, it once reached the highest price of $146.82 in history, and once held the position of the industry leader.

At that time, Zhang Xuan, CEO of Easy Car, once said that Easy Car would remain relatively independent after privatization, and at the same time, through cooperation attempts with Tencent in different fields, we will strive to have a qualitative improvement and qualitative leap in efficiency and volume.

Facts have proved that Easy Car, which joined Tencent Eco, got continuous support in terms of traffic and content, and soon achieved the overtaking of car home in terms of the number of users.

According to the third-party data company Aurora’s Q2 Mobile Internet Industry Data Research Report in 2021, among the mainstream car information apps, the car-easy application is outstanding. In Q2 this year, the number of active users increased rapidly compared with the same period of last year, with an average MAU of 31.773 million, a year-on-year increase of 57.2%, ranking first in the industry since Q4 in 2020.

In addition, the incremental gap between Easy Car and car home is widening. In 2021, the number of new users of Easy Car in Q2 is more than double that of car home, with a gap of 13.672 million. On the other hand, in car home, the monthly users have been declining in the third quarter of 2020, and they are even infinitely close to the car owners in the latest quarter.

It is understood that with the support of bytes, the car owner pays more attention to the sharing of the owner’s real feelings and the output of fun and interesting content around the car. In the new media communication, knowing the car emperor is the "perfect fire" of marketing routines. Recently, the video of the collision between Beiqi Extreme Fox and BYD Han has exploded out of the car circle.

Some senior media people in the automotive industry said that no matter how innovative the new media communication mode is, people’s demand for high-quality content has not changed, only the consumption habits of users have changed, and the automotive media platform is the same. With the ability to continuously provide high-quality content, it is not afraid of any challenges.

At this point, thanks to the advantages of the superposition algorithm, I understand that Che Di abandoned the forums and pictures that car home still sticks to, tilted resources to video content, enabled users to prefer short video and live broadcast modes, and produced more targeted content, so the traffic accumulated faster.

Easy Car has also set up an "intelligent editorial department". The content and video produced by the machine are intelligently pushed for users through a personalized recommendation engine, and users are set up to retain and operate to AI marketing.

According to Aurora data, in 2020, the average number of new users of Easy Car Department will reach 170,000, ranking first; The number of new users who know the car is 153,000, and the number of new users in the car family is close to 150,000.

In addition to user data being overtaken, car home is not as good as its rivals in terms of the number of dealers and media revenue.

After being privatized, Easy Car has no new financial data to disclose. However, according to Zhang Xuan ‘an, the number of dealers cooperating with Easy Car ranks first in the industry. By the end of 2020, the number of contracted dealers was 22,000, with a renewal rate of 85%.

Car home is also not the preferred platform for the advertising of automobile brands. According to the data of "Inventory Report of Marketing Insights in Automobile Industry in 2020" released by QuestMobile, among the platforms including vertical platform, long video, short video and information flow, Easy Car will account for 22.2% of the advertising media for TOP10 new models in 2020, becoming the first choice platform for automobile manufacturers to advertise new cars, while car home’s share is only 17%.

By the close of September 14th, car home’s share price was HK$ 87.3, with a market value of HK$ 44.47 billion, which was over 50% lower than the first day of listing in March.

Who is to blame for car home’s "decline"?

From all aspects of performance, Easy Car seems to have taken the top spot in the industry and become a new head player. The industry structure has changed, and the position of car home’s "boss" has changed hands. Who is to blame?

Like Easy Car, car home has also experienced a change in equity. In 2005, car home website began to operate, and eight years later, Li wanted to bring the company to Nasdaq.

In June, 2015, Li Xiang left car home, stepped down as president, founded Chehejia, and devoted himself to new energy vehicles. After Li wants to leave, the management of the company led by car home CEO Qin Zhi, as well as Boyu, Gaoyou Capital and Sequoia China are going to privatize at the price of $31.50 per ADS.

Unexpectedly, Telstra, the largest shareholder, did not accept this privatization plan, but sold its 47.7% shares to China Ping An Insurance Group for US$ 1.6 billion, and the transaction price was valued at US$ 3.376 billion, which was lower than the management’s privatization offer.

On June 25th, 2016, Telstra and Ping An Trust officially completed the equity delivery. Ping An Trust became the largest shareholder in car home with 47.4% equity, and the shares of car home founder Li Xiang and CEO Qin Zhi were diluted to 2.6% and 2.9% respectively. At the same time, China Ping An made a big change in the senior management team of car home, CEO Qin Zhi and CFO Zhong Yiqi were replaced, and Ping An officially took over the company.

The new management made major adjustments at the strategic level, cutting off the main money-burning businesses at that time, such as automobile e-commerce and used cars; Reorganize the sales team, increase the efforts to realize cash, and inject Ping An Group’s wolf culture of focusing on efficiency and marketing into car home.

Since then, car home under the rule of Ping ‘an has also had moments of high light. For example, the company’s revenue in 2016 increased by 72.10% year-on-year to 5.96 billion yuan; In 2017, net profit increased by 63.01% year-on-year to 2 billion yuan.

On June 19th, 2018, the highest share price of car home was USD 119.18, and the company’s market value reached USD 13.982 billion. The corresponding market value of Ping An Group’s shareholding was about USD 6.6 billion, which means that its equity investment income in two years reached USD 5 billion, exceeding RMB 30 billion.

Lu Min, the head of car home, also won the first-class medal of Ping An Group.

On the other hand, under the profit-oriented atmosphere, car home failed to keep the purpose of taking users as the center, and the excessive commercialization of content caused users’ dissatisfaction.

Many users have found that car home’s once neutral content has become a "water draft", and the platform is no longer a credible third party, and it was once called "the home of car supports".

After the data such as content quality, word-of-mouth and users declined, it also affected the advertising willingness of the OEM. Moreover, when the automobile industry entered the cold winter in 2019, car home insisted on the price increase of membership fees, which triggered a large-scale collective protest by dealers, and several large dealer groups, such as Zhongsheng, Huge and Express, boycotted it.

Due to various unfavorable factors, car home’s revenue has slowed down. According to the financial report data, the company’s revenue growth rate is only 2.82% in 2020, which is the lowest since listing.

According to the analysis of insiders, at present, in addition to two equal rivals, Easy Car and Know Car Emperor, with the rise of short videos, cars have also diverted a batch of traffic from media people. Under this background, how to create high-quality content to attract users and regain their competitive advantage is a new proposition before car home.

Recently, AITO, a new star in the field of domestic new energy vehicles, has once again attracted wide attention from the market. As its flagship model, with its average selling price of about 500,000, it stands out among similar products and becomes a leader in the market.

Not long ago, the news about AITO’s upcoming launch of new models spread like wildfire. It is reported that this new car named is scheduled to be officially launched in 2025. Although the patent drawing of the new car has been exposed in advance, consumers have different opinions on its design. Compared with the model M9 and the new model, the design of the model M8 is particularly unique.

Although there is controversy on the design, the M8 is unambiguous on the body size. It is estimated that its body length will reach about 5 meters, and it will be positioned as a large-size SUV (or medium and large SUV). In the future, it will compete fiercely with brands such as Ideal and Weilai.

Regarding the price of the new car, the market generally predicts that the price of the main selling model of the M8 will be around 400,000. At the same time, some analysts believe that its starting price may drop to around 350,000 to attract more consumers. This price range just fills the gap between the M9 and the new M7.

In terms of configuration, the M8 will undoubtedly carry the latest scientific and technological achievements of HarmonyOS Zhixing. This includes HarmonyOS cockpit, global 800V platform, Huawei Gankun ADS 3.0 (or higher version), giant whale battery and Turing chassis (equipped with variable damping shock absorber and intelligent air suspension). According to the existing powertrain layout of AITO, it is expected that M8 will also provide two power options: extended range version and pure electric version.

It is generally believed in the industry that the launch of M8 will further consolidate the position of AITO in the new energy vehicle market. With its comprehensive equipment, the strong endorsement of Huawei technology and the appearance similar to that of Wenjie M9, Wenjie M8 is expected to achieve similar sales performance in the future market. This is undoubtedly an opportunity worth looking forward to for the AITO community.

When 2019 officially became history, everything has been finalized. For China’s industry, the cold wind was unusually cold this year. From the situation of several happy families in the past to the present, everyone has chosen to hold a group to keep warm in order to survive, which has turned sharply.Market situationIt makes many automobile practitioners feel anxious.

By consulting the information, the online auto market summed up the top 10 most frustrated auto brands in 2019, namely: Dongfeng Fengxing, Zotye, Alfa Romeo, DS, Baowo, Haima, Lifan, Changhe and SWM Siwei. Among them, Dongfeng Fengxing has the lowest known sales target completion rate, only achieving 50.5%.(This is the data after adjusting the sales target twice.), and the most known losses are Lifan and Zotye Automobile. The former is only inIn the first three quarters of 2019, it lost 2.633 billion yuan.! The latter is caught inCompany assets several timesBe enforced by the court、Freeze of major shareholders’ sharesThe situation.

No.1 Dongfeng Fengxing adjusted its sales target twice, and the achievement rate was only half.

Reason for listing: In the second half of 2019, the sales target was reduced by nearly 40%, but it was still not reached.

In order to achieve the 2019 annual sales target, Dongfeng is popular.At the end of 2018, the senior management of the company was completely "changed". The former general manager Xuan Ying, the secretary of the Committee Tan Liuming, the vice president Mo Rongbo and Mao Weiguo were all replaced. newly appointedAfter general manager Tang Jing took office,Dongfeng Fengxing set a sales target of 230,000 in early 2019, but the sharp decline in sales in the first half of the year forced it to reduce its target to 140,000 vehicles by 40% in the middle of the year. However, despite this, Dongfeng Fengxing did not meet expectations. In 2019, only 116,153 vehicles were sold, and the secondary adjustment sales target value was still not reached.

The main reason for the high-digit decline in company sales is the core products.Continued weakness of the popular T5 series.. In March 2019, Dongfeng released the extended version of T5 — — T5L, I thought this car could save the decline of T5 to a certain extent, but I didn’t expect consumers to buy it. In the second half of the same year, Dongfeng Fengxing launched the national VI version of T5/T5L, but it still had little effect.

No.2 zotye automobile　Wage arrears, layoffs and company assets are enforced by the court.

Reasons for listing: indelible brand imprint — — Lack of high imitation core competitiveness

"Half angel, half devil" is an appropriate description of Zotye cars in the past. This independent brand, which once won the public’s attention by "high imitation" luxury cars, has also won the favor of many customers because of its outstanding cost performance. However, this simple and rude development model is not reliable. When other China brands start to develop independently, Zotye’s existence is very striking. In 2019, for Zotye, it is already at stake! The data shows that in the first three quarters of that year, the cumulative sales volume of Zotye Automobile was only 134,600 units, with a year-on-year plunge of 32% and a huge loss of 759 million yuan.

In addition, Zotye Auto has been mired in a series of negative storms such as unpaid wages, layoffs and default on loans. The shares of Tieniu Group, the controlling shareholder of the company, were frozen by the judiciary on November 7 of the same year due to contract disputes. In the case that the company’s cash flow is already in jeopardy, Zotye still needs to repay the loan of 615 million yuan owed to Bike Power Battery and overdue liquidated damages.

No.3 Alfa Romeo is a good car, but its brand image is disgraced.

Reasons for listing:5.8% off sale, buyGhibli sent Giulia

Alfa Romeo officially entered the China market in 2017, bringing Giulia and Stelvio. Giulia is a medium-sized car, which attracted the attention of many performance car enthusiasts at the beginning of its listing. It is equipped with the same 2.9T engine as Ferrari, and the acceleration of 100 kilometers takes only 3.9 seconds. The 350 limited-edition models launched at the time of launch were robbed on the e-commerce platform.

By 2018, Alfa Romeo’s sales in China had declined. In 2019, it was getting closer and closer to the implementation of the national six emission standards. In order to digest a large amount of inventory, all localities launched a series of profit-making activities, including 6.5% off group purchase, buying Maserati Ghibli for Giulia and 5.8% off, but few people paid attention to it.

Alfa Romeo, which has a big diving price, has even lower purchase threshold than the mainstream joint venture models of the same level, but its high maintenance price is a high wall in front of consumers. Previously, a Stelvio had a rear-end collision with the front car. In the case that the front face was damaged, the hood was deformed and bulged, and the damage was not particularly serious, the maintenance quotation showed that the maintenance cost was as high as 110,000 yuan.

The rapid decline of Alfa Romeo is not limited to China, and ALFA 4C officially stopped production in 2019 due to poor sales in overseas markets. In addition, the merger of FCA Group and PSA Group has also affected the future of Alfa Romeo. The number of products announced in the previous five-year plan has been reduced from 7 to 4.

No.4 Brilliance China’s annual sales volume is only over 20,000 units.

Reasons for listing: few products, slow iteration speed, and dealers quitting the network.

Compared with the heyday of the joint venture company, the voice of the independent passenger car brand Brilliance Zhonghua has been very small, which is the lowest brand in China.In 2019, China’s cumulative sales volume was only over 20,000 vehicles, down about 70% year-on-year. What makes China "frustrated" most is the medium-sized SUV— — China V7, even in the case of adding 1.8T models, has not brought it increment.

In addition, Brilliance wanted to use BMW as an endorsement and spent huge sums of money to develop a modular platform — — M8X, equipped with BMW Prince series engines. However, judging from the current situation, M8X has not brought substantial benefits to China, and the first model, Zhonghua V7, based on this platform can be described as "a bad start". At the same time, I have always wanted to use the cooperation with BMW to promote the "helm" of Brilliance’s independent business sector — — Qi Yumin also stepped down in 2019, which had some influence on Chinese brands.

No.5 DS is a "luxury brand" with less sales than Ferrari sports cars.

Reasons for listing:The accumulated loss was nearly 5 billion yuan, which was abandoned by both shareholders.

DS is a luxury brand under PSA (Peugeot Citroen Group), which is produced and sold by Changan PSA, a joint venture company. At present, there are five domestic models. During 2013-2015, the performance of DS in China market was remarkable, and then it began to decline rapidly. In the past few years, the joint venture company did not give up the DS brand, and launched a brand-new product DS 7 in 2018. However, from the follow-up market feedback, this heavy model did not meet expectations at all. In 2018, the annual sales volume of DS was less than 4,000 vehicles, and only about 2,000 vehicles were sold in the first 11 months of 2019, even less than the monthly sales volume of a model of other similar enterprises.

Along with the sales slump, there are huge losses and idle production capacity. According to the financial report of Changan Automobile on September 30, 2013-2019, the cumulative loss of Changan PSA’s equity income is 2.455 billion yuan. We must know that Changan Automobile only holds half of the equity of Changan PSA, which means that the accumulated loss of Changan PSA in the past six years is as high as 4.91 billion yuan! In November 2019, PSA Group announced that it planned to sell its 50% stake in Changan PSA; On the last day of 2019, Changan Automobile also announced the transfer of the remaining 50% equity of Changan PSA. Being abandoned by both shareholders at the same time, DS is really miserable!

No.6 Baowo Automobile became the "self-satisfied" brand spokesperson after being acquired by Baoneng.

Reasons for listing:Baowo, what have you been doing these two years? Maybe you don’t know yourself.

Since 2015, Baowo has brought himself many hats such as "German luxury", "BBA+B" and "engineer", but the high profile set by the brand people has not improved Baowo’s business a little, and it fell to the bottom in the second year of its debut. At the same time, the huge gap between the exaggerated brand tonality and the actual product strength has also made many consumers feel that their IQ has been insulted.

Nowadays, the sales volume of Baowo continues to be sluggish and the brand is notorious. Even Lu Zhengyao, who has superb "financial skills", is powerless to change it. This capital master who wanted to rely on the Shenzhou system to empower Baowo may not have thought that a strong enough Shenzhou system would have to "rest" when it came to Baowo. Perhaps, the only thing that Baowo can remember this year is the magic advertisement in the circle of friends, which was presented by Lang Yongchun and Tiger Brother online celebrity, Tik Tok.

No.7 Haima Automobile is the main business, and building a car is just a hobby.

Reason for listing: In 2019, it sold 25,000 units and earned more than 70 million by selling houses.

Haima Automobile, with a history of 31 years and 3 million users, also had a bad year in 2019. By the end of November of that year, the cumulative sales volume of Haima was only 25,610 vehicles, a year-on-year decrease of 58.95%.

In April of that year, its stock was subject to "delisting risk warning" and its name was changed from "Haima Automobile" to "*ST Haima". Based on this, Haima had to "sell the house to protect the shell". On November 23, 2019, ST Haima announced that 318 of the 401 properties (Shanghai and Haikou) previously put up by the company had been successfully sold, and the accumulated funds received exceeded 120 million yuan, which affected the net profit by 73.64 million yuan. Although this move has alleviated the current financial pressure of Haima Automobile to some extent, it is not a long-term solution after all. Adjusting its own strategy and introducing external investment may be the best solution.

No.8 Yin Mingshan’s dream of building a car was broken

Reason for listing: sell! Production qualification, sell! Football team, what else to sell?

Lifan is undoubtedly the most dangerous among the top 10 automobile brands: data show that in the first three quarters of 2019, some bank loans of Lifan reached 12.782 billion yuan, and loans from non-bank financial institutions reached 10.486 billion yuan. Lifan has tried a series of ways to save himself from selling teams, factories and qualifications, but these can only be regarded as a drop in the bucket. In order to avoid the break of Lifan’s capital chain, the Chongqing Municipal Government specially set up a creditor’s bank committee for Lifan.

Lifan used to be an important member of private car companies in China, and the situation that it has fallen to now has a lot to do with the deviation of its own strategy. It is reported that if Lifan can get out of the "ghost gate" in the future, it will return to its main motorcycle business.

No.9 the model of "infighting" of Changhe automobile enterprises

Reason for listing: Changhe is a "good boy" that no one dares to touch and manage in BAIC.

Since the completion of "Dachanghe" business restructuring and upgrading to a secondary company under BAIC Group, Changhe Automobile seems to have slowed down all of a sudden. In fact, the successive leaders of BAIC in turn have been consumed by "infighting". Some employees in Changhe issued a document sighing that "infighting is fierce, management is chaotic, wages are low, and there is no benefit and no prospect."

In terms of products, at present, Changhe Automobile has a total of seven models on sale, including SUV, A-class sedan, MPV and new energy series, including three new energy vehicles that are not very popular. Although Changhe has not announced the actual sales figures in 2019, we can boldly predict that it is almost impossible to complete the annual sales target of 250,000-300,000 vehicles previously proposed.

No.10 SWM The moon abroad is not round.

Reason for ranking: "Italian descent" failed to save Sway.

Chongqing’s automobile manufacturing industry has suffered a great impact in the past two years, and SWM Siwei is also on the list with Lifan this time. Compared with the above brands, this self-proclaimed car company with "Italian ancestry" actually made a lot of noise in 2019, and it successively launched three new SUVs, namely G01 F (sports version), G01National Sixth Edition and G05. In order to improve sales, SWM Sway also launched a 20% discount car purchase activity for the 2019 Sway X7, and several other products also have different discounts.

However, after all, building a car is not achieved overnight. Without mature technology accumulation and economies of scale, SWM Siwei will not be able to compete with mainstream independent brands. As a late-start enterprise, it is still unknown whether SWM Siwei can be as lucky as Lifan, and the local government will take the lead in improving the operation of the enterprise.
