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.

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.

Image source: data mining workers

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.

　　On the morning of July 17th, the State Council Press Office held a press conference to introduce the national economy in the first half of 2023 and answer questions from reporters.

　　Fu Linghui, spokesman of the National Bureau of Statistics, said that in the first half of this year, the overall economic recovery in China improved, and the overall economic operation showed a good trend of recovery. With the economy and society fully returning to normal operation, the main indicators have generally improved, new kinetic energy has grown stronger, the quality of development has steadily improved, and people’s lives have continued to improve, laying a solid foundation for achieving the expected goals of economic and social development throughout the year.

　　From the next stage, although the external environment is becoming more complicated and severe, and the domestic economic development is also under pressure, the fundamentals of China’s long-term economic improvement have not changed, and the characteristics of strong resilience, great potential and full vitality have not changed, and the conditions for supporting high-quality development have not changed. With the accumulation of positive factors promoting development, the economy is expected to continue to recover.

　　First, the pull of consumption continues to increase. Since the beginning of this year, all aspects have actively resumed and expanded consumption, and the consumption potential has been gradually released, which has significantly enhanced the impetus to economic growth and played an important role in promoting economic recovery. In the first half of the year, the contribution rate of final consumption expenditure growth to economic growth reached 77.2%, which was significantly higher than that of last year. In the next stage, the employment situation will continue to improve, and residents’ income will continue to increase, which will help to promote residents’ consumption ability and willingness. At the same time, promoting the sales of new energy vehicles and green smart home appliances will be effective, which will help to expand consumption and promote economic recovery.

　　Second, the service industry is developing well. With the full recovery of normal operation of the economy and society, the growth of the service industry has obviously accelerated, especially the contact service industries such as wholesale and retail, accommodation and catering, and transportation have rebounded significantly, contributing to economic growth. The contribution rate of service industry growth to economic growth in the first half of the year exceeded 60%. In the next stage, the consumer demand for services such as cultural tourism, fitness and sports will be released faster, and the productive demand for R&D, design and business exhibitions will increase, which will drive the service industry to maintain rapid growth and help the economy run stably. Judging from the business activity index of service industry, the business activity index of service industry was 52.8% in June, which was in the boom zone for six consecutive months.

　　Third, new kinetic energy has developed and grown. China has deeply implemented the innovation-driven development strategy and strengthened its strategic scientific and technological strength. Modern information technology, artificial intelligence, big data and other technologies are widely used, and innovative achievements are constantly emerging, and new industries and new products are growing well. Since the beginning of this year, the domestic large aircraft C919 has completed its first commercial flight, the world’s first 16 MW offshore wind turbine has been hoisted, and scientific and technological innovation has continued to empower high-quality development. We should also see that the consumption growth of smart products has also continued to increase, which has also driven the growth of related manufacturing industries. In the first half of the year, the added value of smart consumer equipment manufacturing industry increased by 12% year-on-year. At the same time, around the project of overcoming the "bottleneck", the manufacturing industry of semiconductor-related industries grew rapidly in the first half of the year, and the added value of the manufacturing industry of special equipment for semiconductor devices increased by 30.9%. In terms of products, some new materials and intelligent products grew rapidly. In the first half of the year, the output of aerospace aluminum, industrial control computers and systems increased by 23.3% and 34.1% respectively. The continuous enhancement of innovation kinetic energy in the next stage will inject new impetus into economic development.

　　Fourth, the effectiveness of green transformation has emerged. The pace of green energy development has been accelerated, green production and lifestyle have been accelerated, and the synergistic development effect of green transformation and economic growth has been constantly emerging. In the first half of the year, the output of new energy products such as new energy vehicles, solar cells and charging piles increased by 35%, 54.5% and 53.1% respectively, and the export of "new three products" represented by lithium batteries, solar cells and electric manned vehicles increased by 61.6%. In the next stage, green development is full of kinetic energy, which will help the transformation of kinetic energy of economic growth while promoting the quality improvement of economic development.

　　Generally speaking, since the beginning of this year, China’s economy has gradually got rid of the impact of the epidemic and returned to the normal operation track, showing a good recovery trend. From the perspective of the whole year, despite the pressure and challenges, with the improvement of employment, the increase of residents’ income, the gradual strengthening of domestic demand, the optimization and adjustment of supply structure, and the growth of new kinetic energy, the economy will recover steadily and the quality of development will continue to improve. Therefore, we are fully confident, qualified and capable of accomplishing the expected goals and tasks of economic and social development throughout the year.

　　CCTV News:On January 18th, the State Council Press Office held a press conference to introduce the operation of agriculture and rural economy in 2022 and answer questions from reporters.

　　Zeng Yande, chief agronomist of the Ministry of Agriculture and Rural Affairs and director of the Development Planning Department, briefly reported the operation of the agricultural and rural economy in 2022.

　　2022 is an extraordinary year. The Ministry of Agriculture and Rural Affairs and the National Rural Revitalization Bureau conscientiously implemented the spirit of the important speech and instructions of the Supreme Leader General Secretary, implemented the decision-making arrangements of the CPC Central Committee and the State Council, effectively responded to the epidemic situation and serious natural disasters in COVID-19, went all out to ensure supply, overcome difficulties and keep the bottom line, made concerted efforts to promote revitalization, and fully completed the annual goals and tasks, providing a solid foundation and strong support for the overall stability of the economy and society.

　　First, grain production has achieved another bumper harvest, and the supply security foundation has remained stable. Grain output reached a record high. The sown area of grain was 1.775 billion mu, an increase of 10.52 million mu over the previous year, and the output was 1,373.1 billion Jin, an increase of 7.4 billion Jin, which remained above 1.3 trillion Jin for eight consecutive years. The effect of soybean oil seed expansion is obvious. The soybean area was 154 million mu, an increase of 27.43 million mu over the previous year, the highest year since 1958. The output was 20.28 million tons, an increase of 3.89 million tons. The rape area reached 109 million mu, an increase of nearly 4 million mu, and the total output of oil crops was 36.53 million tons, an increase of 1.1% over the previous year. Due to the increase in supply and consumption saving, the self-sufficiency rate of edible vegetable oil increased by 1.6 percentage points. The production of live pigs developed steadily. By the end of 2022, the number of fertile sows in China was slightly higher than the green and reasonable regional upper limit of capacity regulation. The annual pork output was 55.41 million tons, an increase of 4.6% over the previous year. At the same time, the production of beef, mutton, milk and aquatic products increased in an all-round way, and the supply of vegetables and fruits was stable.

　　Second, the industrial employment belt has been strengthened, and the results of poverty alleviation have been continuously consolidated. Monitoring assistance is further optimized. Farmers who are at risk of returning to poverty should do their best and help them. More than 65% of the monitored objects have eliminated the risk of returning to poverty, and the rest have also implemented assistance measures. The effect of industry leading agriculture is obvious. The proportion of subsidy funds for rural revitalization promoted by the convergence of central finance for industrial development exceeds 55%, and every poverty-stricken county has cultivated 2-mdash; Three characteristic leading industries, nearly 3/4 of the people out of poverty have established a close interest relationship with new business entities. Going out to work remains stable. In the whole year, the employment scale of poverty-stricken laborers was 32.78 million, exceeding the annual target of 2.59 million.

　　Third, science and technology and equipment are strongly supported, and modern agricultural construction continues to advance. The revitalization of seed industry has been further promoted. The general survey of agricultural germplasm resources was basically completed, and 120,000 agricultural germplasm resources were newly collected, 330,000 livestock and poultry germplasm resources and 78,000 aquatic germplasm resources were collected and produced. Key agricultural core technologies have been tackled in an orderly manner, major agricultural biological breeding projects have been launched and implemented, and the pilot application of genetically modified corn and soybean industrialization has progressed smoothly. The protection of cultivated land has been intensified. The task of building 100 million mu of high-standard farmland in the whole year was overfulfilled, and the cumulative construction target of 1 billion mu was achieved as scheduled. The implementation of conservation tillage covers an area of 83 million mu, and the pilot task of the third national soil survey was generally completed. Breakthrough in the creation of agricultural machinery and equipment. 240 horsepower stepless speed change tractors, rape transplanters and other short-board machines were successfully mass-produced, and the loss rate of grain machinery was controlled within 3%.

　　Fourth, the transformation of production methods was accelerated, and the green transformation of agriculture continued to advance. Collaborative promotion of agricultural non-point source pollution control. The utilization rates of chemical fertilizers and pesticides all exceeded 41%, and the utilization rates of livestock manure, straw and agricultural film exceeded 78%, 88% and 80% respectively. The ecological environment in key river basins has been improved rapidly. The ten-year ban on fishing in the Yangtze River has been vigorously promoted, and the protection of aquatic biological resources has continued to improve. The effect of deep water saving in the Yellow River basin has begun to show, and the agricultural ecological environment problems have been treated. The supply of green and high-quality agricultural products increased. Agricultural production and the "three products and one standard" of agricultural products have been further promoted. The output of green, organic and geographical indications has reached 11%, and the pass rate of routine monitoring of agricultural products quality and safety has reached 97.6%.

　　Fifth, rural industries have been cultivated and expanded, and channels for increasing farmers’ income have been continuously broadened. The processing and circulation of agricultural products has developed steadily. It is estimated that the operating income of agricultural products processing industry above designated size will exceed 18.5 trillion yuan, an increase of about 4%, and support various market entities to build more than 16,000 cold storage and preservation facilities for agricultural products. The development of new industries and formats in rural areas was accelerated. Rural leisure tourism has resumed development, and the online retail sales of agricultural products are expected to increase by about 10%. Rural employment and entrepreneurship have a good momentum, and the local employment rate is over 90%. Upgrading the construction of agricultural parks. 40 new industrial clusters with advantages and characteristics, 50 national modern agricultural industrial parks and 200 strong agricultural towns will be built, and the rural industrial base will be further consolidated. Driven by industry and employment, the annual per capita disposable income of rural residents reached 20,133 yuan, a real increase of 4.2%, and the per capita income ratio of urban and rural residents was 2.45, which was 0.05 lower than that in 2021.

　　Sixth, rural construction has been carried out in an all-round way, and the living conditions of farmers have been continuously improved. Renovation and improvement of rural human settlements. The penetration rate of sanitary toilets in rural areas in China exceeds 73%, more than 90% of domestic garbage in natural villages has been collected and transported, and 95% of villages have carried out cleaning operations. The construction of rural public facilities was promoted in an orderly manner. The construction of industrial roads, resource roads and tourist roads in rural areas was accelerated, water supply and power supply, network communication, farmers’ housing and other facilities were gradually improved, and the level of public services such as rural education, medical care and old-age care was steadily improved. The effectiveness of rural governance has been continuously enhanced. A total of 199 demonstration villages and towns and 1992 demonstration villages have been established nationwide, and governance methods such as point system, list system and digitalization have been comprehensively promoted.

　　Seventh, the expansion of rural reform has deepened, and the kinetic energy of rural development has continued to increase. The key reform tasks have been steadily advanced. After the expiration of the second round of land contract, the pilot project was extended to 21 provinces for another 30 years. Two pilot projects, namely, the reform of homestead system and the special rectification of rural land occupation and housing construction, were carried out in an orderly manner, and the results of the reform of rural collective property rights system were consolidated and improved. The main body of new agricultural management has developed and expanded. Family farms and farmers’ cooperatives reached 3.9 million and 2.22 million respectively. Agricultural socialization service covers an area of 1.87 billion mu and drives more than 89 million small farmers. Trade in agricultural products grew rapidly. The total import and export volume reached $334.32 billion. Among them, imports were US$ 236.06 billion, up by 7.4% over the previous year, and exports were US$ 98.26 billion, up by 16.5% over the previous year.

　　Generally speaking, the agricultural and rural economic development in the past year has withstood multiple tests, achieved more than expected results, stabilized the basic disk and consolidated the ballast stone. This year, the Ministry of Agriculture and Rural Affairs and the National Rural Revitalization Bureau will fully implement the spirit of the 20th National Congress of the Communist Party of China, conscientiously implement the decision-making arrangements of the CPC Central Committee and the State Council, anchor the goal of building an agricultural power, fully adhere to the two bottom lines of ensuring national food security and not returning to poverty on a large scale, solidly promote key tasks such as rural development, rural construction and rural governance, build a livable and beautiful countryside, and make new progress in comprehensively promoting rural revitalization and accelerating agricultural and rural modernization.

There are many people who blindly look at the vehicle power parameters when buying a car. In fact, the larger the value, the better the experience. Today, I picked a car to introduce to you, and it is. Without further ado, let’s take a look.

Take a look at the appearance of Skyworth EV6 first. The front shape of Skyworth EV6 is dignified and looks very delicate. The headlights are very in line with the consumer’s aesthetic, and the overall look is very elegant. The car is equipped with automatic opening and closing, delayed closing, etc. To the side of the body, the body size of the car is 4720MM*1908MM*1696MM. The car adopts a youthful and personalized line. The side of the car presents a delicate design style, with large-sized and thick-walled tires, which leaves a very fashionable feeling. In terms of the rear, the overall shape of Skyworth EV6’s rear echoes the front face. The taillights look very cold, and the overall look is very young and fashionable.

Coming to the Skyworth EV6 car, the front face of Skyworth EV6 looks very avant-garde, and the overall visual effect is very distinctive. The steering wheel shape of the car is bright, and it is made of leather material, which looks a little more simple. From the central control point of view, with the 15.6-inch touch LCD central control screen, the interior style is impressive and stable. The dashboard and seats also feel good. Let’s take a look. The dashboard of the car presents a delicate design style, and the design is relatively cold. The car adopts leather seats, which are wide and thick, exquisite in materials, and comfortable to ride.

Skyworth EV6 is 150KW, with a total torque of 320N.m, a maximum speed of 150km/h, and a maximum cruising range of 520km. The electric vehicle has a good cruising range and meets daily needs.

In terms of configuration, Skyworth EV6 is equipped with driving mode selection, remote control key, Bluetooth key, rear wiper, in-car ambient light, traction control (ASR/TCS, etc.) and other configurations.

This car has already been introduced, and I believe that many users who buy a car have taken a fancy to its comfort and practicality. If you are also concerned, you might as well experience it.

Zeekr Krypton 001 is not expensive compared with the same class.

Extreme krypton 001 is the flagship model of extreme krypton car, which is positioned as a medium-sized and large-sized car with a starting price of 300,000 yuan. According to the data of the car body, the car body is 4970*1999*1560(1548)mm and the wheelbase is 3005mm, which is outstanding in the same class.

The price range of 2024 Extreme Krypton 001 is 269-329,000 yuan, and the prices of medium and high distribution are lowered. For example, the entry-level version has the same price, but the configuration has been greatly improved, such as 19-inch wheels and LED matrix headlights, which are standard, and there are rich intelligent driving assistance functions. Moreover, the WE version upgrades the 21-inch 4-piston calipers for free, all colors in the whole system are free, and zad’s complete driver assistance function is free for life.

In terms of configuration, Krypton 001 is also excellent, including front seat heating, HUD head-up display, steering wheel heating, rear seat heating and ventilation, wireless charging of mobile phones, etc., and also provides front sports style seats.

At the same time, the new Krypton 001 also has advantages in power and battery life. For example, the WE version of the 100kWh rear-drive version is equipped with a 100kWh Kirin battery, and the CLTC cruising range is 750 kilometers.

Compared with the same class of fuel vehicles, the price is at the mainstream level. On the whole, Krypton 001 is competitive in price, rich in configuration and high in cost performance, and will not be more expensive than the same class models. Its main competing products are Tesla model Y, Aouita 12, Han, Xingyuan ES, etc., but Extreme Krypton 001 has its own advantages in terms of price, configuration and battery life.

At the entrance of the shield assembly workshop of China Railway Equipment, a blue and white shield cutter head with a diameter of nearly three stories is being hoisted on a heavy transport truck, and it will be put into the Tel Aviv subway tunnel project in Israel soon. This is also the eighth shield machine exported by China Railway Equipment to Israel in recent years. In addition to Israel, the company’s shield equipment exported to Austria, Italy, Portugal, Qatar and other countries has also been rolled off the assembly line and installed …

How did this company make China people’s own shield machine? And how to make China’s shield machine go to the world by virtue of its strong strength? A few days ago, the reporter walked into Zhengzhou headquarters of China Railway Engineering Equipment Group Co., Ltd. and felt the invincible power of big countries.

Build China’s own shield machine.

According to the relevant person in charge of China Railway Equipment, full-face tunnel boring machines are divided into hard rock boring machines, earth pressure balance shield machines and mud-water balance shield machines according to different applied geological conditions. In China, the latter two types are commonly referred to as "shield machines". This kind of equipment is called "the king of construction machinery", which integrates mechanical, electrical, hydraulic, sensing, information, mechanics, guidance research and other technologies. A shield machine is several stories high, weighs thousands of tons, and has tens of thousands of parts. The control system alone has more than 2,000 control points.

Wang Dujuan, chief expert and deputy general manager of China Railway Engineering Equipment Group, told the reporter that in the past, underground tunnels were the difficulties of many major projects. Traditional excavation and excavation relied on methods such as pneumatic drilling, blasting and stone slag planing, which had low safety and efficiency.

In order to speed up the infrastructure construction, in the 1990s, China imported two hard rock boring machines from abroad at a cost of 700 million yuan, which were used for the construction of Qinling Tunnel on Xikang Railway. However, these imported machines are not only expensive, but also cost more for follow-up services.

Wang Dujuan and his colleagues sprouted a dream from their hearts: China people must build their own shield machines! Later, she and her colleagues made repeated investigations and attempts, and started over and over again … In April 2008, we finally successfully developed the first composite EPB shield machine with independent intellectual property rights in China. Subsequently, the prototype was applied to the Tianjin subway project, which not only made the excavation speed fast, but also controlled the surface settlement within 3 mm. After the success of the first battle, this meritorious shield machine was officially named "China Railway No.1".

Polishing high-end equipment and manufacturing "business cards"

After the breakthrough of domestic shield machine from scratch, it is inseparable from the continuous innovation of technology to continue to achieve from scratch to strength and rank among the top in the world.

In the aspect of intelligent product innovation, the traditional tunnel boring machine (TBM) construction operation is to dig horizontally, but when digging wells, for example, the TBM needs to dig vertically. In order to meet the demand of vertical excavation, China Railway Equipment has carried out scientific research for another ten years.

"Why don’t we apply the concept of full-face tunnel boring machine to shaft boring machine, develop new products and open up new categories?" In December 2012, Li Jianbin, then Party Secretary and Chairman of China Railway Equipment, said at an internal technical seminar. After analysis and discussion, the participants immediately began to prepare for the research and development of full-face hard rock shaft boring machine.

In order to design a shaft boring machine with few people, no one, mechanization and intelligent construction, R&D personnel personally built a shaft with a depth of 690 meters, and tackled the slag tapping technology, propulsion technology and remote control technology one by one.

Finally, in 2021, the full-face hard rock shaft boring machine developed and manufactured by China Railway Equipment for 10 years was successfully used, which overcame the world problem of shaft boring for 1,000 meters and realized the concept of "drilling without lowering the well, intelligent boring" for the first time.

At present, China Railway Equipment is actively deploying intelligent shield machines and future boring machines, facing the forefront of industrial technology development, and carrying out reserve research on new rock-breaking technologies such as laser and water jet, tool-changing robots and unattended intelligent tunneling technologies. It has successively won the first and second prizes of national scientific and technological progress, a single champion demonstration enterprise in manufacturing industry, a gold medal in China’s good design, a silver medal and a gold medal in China’s patent. In 2020, China Railway Equipment was successfully selected as the first batch of "Science and Technology Reform Demonstration Enterprises".

"selling the world" opens a new journey

Wang Jinsong, head of the equipment quality management department of China Railway, told the reporter that the underground construction environment of roadheader is poor, the safety risk is high, and the equipment requirements are high. How to control the product quality is the primary problem faced by production enterprises. China Railway Equipment pays attention to detail control, focuses on product quality upgrading, implements lean production, implements quality one-vote rejection system, process real-name registration system and three-level inspection system, and fully guarantees product quality.

In recent years, China Railway Equipment has been climbing the technical peak of roadheader, and its products and services have been widely recognized by the international market. In 2021, the hard rock roadheader "Caucasus" made in China was officially excavated in the Georgian highway tunnel. The equipment has a diameter of 15.08 meters and a total weight of 3,900 tons. It is completely designed by China and China standards, and is independently manufactured by the Chinese side. It has an efficient tunneling capability under the conditions of long distance and large buried depth. This equipment has set a new record for the excavation diameter of hard rock roadheader in the world, and it is also a powerful witness for China Railway Equipment to serve the global underground engineering construction.

In recent years, the tunnel boring machine produced by China Railway Equipment is becoming a new domestic product of "Belt and Road". In 2015, China Railway Equipment won the bid for multiple shield machines in Tel Aviv subway in Israel at one time; In 2018, it won the bid for the Copenhagen project in Italy and Denmark to enter Europe; Successfully exported to France in 2019 for the Paris subway project; In 2020, the slurry shield machine exported to Poland …

In the first half of this year, China Railway Equipment actively overcame the impact of the epidemic, seized opportunities and overcome difficulties, and went all out to promote the efficient implementation of various economic indicators. The amount of newly signed contracts increased by 58% year-on-year, achieving a contrarian rise. Up to now, the cumulative order has exceeded 1400 units and exported to more than 30 countries and regions.

At present, the company’s products are widely used in foreign railways, highways, subways, water conservancy, mines and other construction fields, providing products, services and comprehensive solutions for hundreds of tunnels and underground projects. The production and sales of related equipment have been in the forefront of the world for five consecutive years.

The rise of new energy vehicles is a foregone conclusion, and car companies can only go further if they follow the trend. Even the national team that makes cars has begun to build trams. It is an electric off-road launched by science and technology.Mengshi Technology is a new energy automobile company founded by Dongfeng Motor in 2022.

What is the quality and strength of trams built by old state-owned enterprises? Just look at Warrior 917. Warrior 917 has two models, namely extended range version and pure electric version, and their prices are 637,700 and 697,700 respectively. At the recent Chengdu Auto Show, the Warrior 917 surprised everyone as soon as it appeared.Warrior 917 looks like an armored vehicle, and the performance and configuration of the whole vehicle are enough to make most trams lag behind.

The extended-range version of the Warriors 917 has 816 horsepower, while the pure electric version has 1088 horsepower, and both models use four-wheel drive. 816 horsepower is the first echelon in the power of new energy vehicles.Warrior 917 not only has good start and acceleration performance, but also has excellent off-road performance.

Even in the wild where there is no road, Warrior 917 can drive freely. Obviously, the power of warrior 917 is worthy of the word warrior.Its strong power is a reflection of Dongfeng Motor’s profound strength.

In terms of battery life, the extended-range version of the Warrior 917 has a pure electric cruising range of 200 kilometers, while the pure electric version has a cruising range of 505 kilometers. For the extended-range version of the Warrior 917, the pure electric cruising range of 200 kilometers is enough to travel smoothly in the urban area.Even in long-distance or field conditions, the range extender with a displacement of 1.5L can provide long endurance support for the Warrior 917.

For the pure electric version of the Warrior 917, the pure electric endurance of 505 kilometers is not excellent in the tram.But it is also enough to travel smoothly in most parts of the country.

Users who choose off-road vehicles are bold in character, because off-road vehicles themselves reveal unique wildness. The Warrior 917 car body adopts a variety of concave plane designs, with anti-collision beams at the front, spare tires at the rear and high-strength shelves at the top of the car body. The appearance of Warrior 917 is serious and hard.It looks like a beast ready to go, and people have to be afraid of it.

In terms of size, the Warrior 917 is a medium and large S.UV, its length, width and height are 4.987 m, 2.080 m and 1.935 m respectively, and the servicing quality of pure electronic version is 3.293 tons. Obviously,Warrior 917′ s interior space is spacious, and users can get good comfort in the car. Besides,3.293 tons of body letWarrior 917As steady as Mount Tai, sitting in this medium and large SUV is naturally full of security.

600,000-class domestic off-road vehicle, its configuration is enough to surprise everyone. Like the power and appearance, the configuration of the 917 can also be left behind by peers. It can be said that the configuration that new energy vehicles should have,There are basically Warriors 917, and there are other configurations that most trams don’t have.

For example, the Warriors 917 has high-end configurations such as night vision system, active DMS fatigue monitoring, and in-vehicle vital signs monitoring. Because it is an off-road vehicle, the Warrior 917 is also equipped withWading induction system, electromagnetic induction suspension, air suspension, variable suspension adjustment and other configurations.

In addition, the interior of the Warrior 917 is made of genuine leather, such as the steering wheel and seats.The leather texture is really beyond the reach of ordinary interiors.

Warrior 917 has excellent off-road capability, and its hard and serious appearance can give users a full sense of security. At present, there are only a handful of new energy vehicles on the market that can give users such a sense of security. In addition to having hard power,Warrior 917 also has luxurious configuration, which is not only the sincerity of Dongfeng Motor, but also the strength of domestic new energy vehicles.

How about warrior 917?

2024 is probably the first year of the major automobile manufacturers to break through the industry bottom line, less than 200,000 that is equipped with rear wheel steering and lidar, less than 100,000 BYD battery life of 2100km, as low as 130,000 can start modern, the domestic automobile market is really more and more interesting.

However, this is still limited to this year’s automotive industry has just splashed, in the field of new energy D-class luxury cars, the second half that really refreshes your imagination is actually just beginning. The Z9GT with a length of 5 meters 1 + easy three-party technology is here. At the pre-sale price from 339,800, the GT model equipped with three-motor independent drive and rear wheel steering technology has been successfully launched into the D-class luxury flagship car field. According to some data, the current pre-sale order of the Z9GT can reach more than 30 units. So, what is the outstanding place of this GT?

From the perspective of level positioning, the Tengshi Z9GT is positioned as a medium and large-sized car. It is the first model of the Tengshi family "Z" series. It has many differences in design, size and positioning from the mainstream models of the BYD series. Due to its high-end attributes, it is slightly more expensive than BYD’s previous models in terms of overall price, but it will be cheaper than the Looking Up series. For some consumers who like BYD technology but feel that the volume models are not enough to highlight their identity and the price of higher-end models, the Tengshi Z9GT may be a good choice.

In terms of appearance, the new car and JK 001 have a similar hunting style, but the salty and sweet appearance under the careful design of Wolfgang Iger, the elegance of Elegance in motion is just right, especially the double star crown headlight group and the surging surface, with the "Z" shaped decorative line, when the oriental aesthetic implication is embedded in it, the "time hourglass" tail light and the crane hovering tail, and further highlight the sports attributes of the GT model, so that the whole car presents a high-level beauty of elegance and dynamic coexistence.

The length, width and height of the Z9GT are 5195/1990/1500mm respectively, and the wheelbase has reached 3125mm. From the size point of view, it is a medium and large car. As a reference comparison of similar models, the body size of Porsche is 5052x1937x1423mm, the wheelbase is 2950mm, and the body size of the extreme krypton 001 is 4977x1999x1545mm, with a wheelbase of 3005mm. In addition to the width and height of the Z9GT, there is a slight difference with the extreme krypton 001, and its vehicle size is almost no less than that of other competitors.

In terms of overall vehicle space, thanks to the CTB body battery integration technology, the Tengshi Z9GT provides a more superior space utilization rate, both the front and rear rows are very spacious and comfortable, fully satisfying people’s imagination of D-class luxury cars. It is worth mentioning that its seat comfort also adopts graded matching, such as the main driver using a lower R point and seat posture, the co-pilot adopting a zero-gravity buoyancy design, and the rear row provides Spa-class wide seats, providing the driver with a sedentary and tiring driving experience while also taking care of the comfort of different occupants. Coupled with the soft and delicate armrest materials in the front and rear rows, it can be said that the moment you get into the car, the first-class class luxury comes to mind instantly.

In addition, the exquisite ritual sense that can be seen everywhere in the cockpit is also eye-catching. In addition to the huge mid-mounted display screen and the co-pilot screen, the Divale lifting tower, the hidden electric trend, the double 50W wireless super charging floating island, and the segmented sunshade, etc., every detail brings a vivid sense of elegance to intelligent technology travel, especially the front and rear intelligent heating and cooling double refrigerators. Although there are many layouts of refrigerators in the car before, the front and rear are not rare. It can be cold and hot. This advantage is that it can not only take care of the needs of adults who want to drink cold drinks in summer, but also take care of children to drink hot milk. Differentiated care for each group reflects the original intention of family cars.

In terms of power, the Z9GT takes into account both pure electric and plug-in versions, both of which are equipped with easy three-party black technology, but unlike the easy four-party technology, it uses three-motor independent control, the first advantage it brings is high horsepower, of which the EV pure electric version has a maximum power of 710kW and a maximum torque of 1150N.m, while the DM plug-in version consists of a 2.0T engine and three drive motors. The maximum power of the motor is 640kW, which is 1035N.m, and nearly a thousand horsepower. The Z9GT’s performance of running a hundred kilometers into a three-second zone has surpassed the performance of the 12-cylinder engine installed on a luxury car in the era of fuel vehicles. In terms of energy consumption, even the lowest-charged state fuel consumption of 100 kilometers NEDC is only 5.6L.

Of course, in addition to the powerful power, the biggest highlight of Easy’s three-party technology is that it integrates rear-wheel dual-motor independent steering control and VMC vehicle motion control technology, which means that when driving at high speed, a sudden tire explosion or a slippery road slippery, etc., it can perform more refined torque distribution, allowing the car to be highly integrated with the actual car scene, thus bringing safer and ultimate handling performance. At the same time, with the support of the black technology rear wheel steering function, the rear wheel steering angle can reach 10 degrees, which allows the turning radius to be controlled within 5 meters, which means that the Z9GT can be easily manipulated in scenarios such as parking and U-turns.

Based on this, it can be seen that whether it is brand price, space comfort, advanced technology, and powerful power and technical heritage, the Tengshi Z9GT all shows the luxury charm of both quality and strength, especially the easy three-party black technology and ingenious creative equipment, which has raised the D-class luxury connotation in the new era to a new height, satisfying most people’s yearning for GT models "both want and want".

In general, with the past Tengshi brand traffic and its models, and N7N8 by virtue of its own strength to stir the domestic luxury market pattern, the arrival of Tengshi Z9GT at this time is undoubtedly to add another member of Tengshi, the key is to 339,800 the starting price, and throw out the easy three-way technology + plug-in and pure electric dual power, this set of combination fist down, really brought a lot of impact to the D-class luxury car market, after the official sale, personal prediction, it will become the focus of leveraging traditional luxury cars in the second half of the year, then, such a hunting GT, will be your dish?
