Foxconn finally ran away. US President Donald Trump)7 announced on July 26th that Foxconn plans to build a new factory in Wisconsin to fulfill its commitment to invest in the United States. Foxconn will invest $10 billion to build a new LCD factory.

It is said that this will be the largest new investment by a foreign company in the United States in history, but it is only the first of many investment plans of Foxconn in the United States, and there will be more in the future, creating 3,000 new jobs for Wisconsin and having the opportunity to explore the scale of 13,000 people. Trump is quite satisfied with Guo Taiming: "He is a great businessman anywhere in the world."

Getting Foxconn to produce in the United States is a dividend for Apple and American manufacturing. Revitalizing the manufacturing industry in the United States and hollowing out the treatment industry can also be regarded as a great achievement project during Trump’s tenure. It has a strong demonstration effect and driving effect on the return policy of American manufacturing industry. In the past 40 years, the scale of industrial employment in the United States has fallen sharply. Therefore, for many years, the slogan that the United States has been shouting is to let the manufacturing industry return.

For the United States, the purpose of manufacturing return is more about employment and the adjustment of economic structure. Therefore, the United States is striving for advanced and high-quality foreign capital and manufacturing giants to enter. The problem in the United States is that the labor cost is high, the scale of manufacturing industrial clusters is not as good as that in China, and the degree of automation is high, so the number of jobs and employment is getting less and less.

Moreover, Foxconn is the largest supplier and foundry of iPhone. Since the Obama era, the US government has continued to put pressure on Apple, hoping that Cook can move the manufacturing of Apple products back to the United States.

Foxconn’s establishment of a factory in the United States can obviously drive Apple to bring some of the production capacity of the industrial chain back to the United States. It can also help Apple to check and balance Foxconn at home. For example, in the future, Apple can increase its control by cooperating with Foxconn to build factories, investing in capital, and infiltrating forces such as technology operation and placement of Apple executives and core technicians. Even Foxconn’s factory building behavior will also play a leading role for many component manufacturers in Apple’s supply chain.

As early as last year, Apple proposed to Foxconn and Pegatron United Technologies the idea of withdrawing all Asian production lines to the United States. At that time, many suppliers did not respond, and Pegatron Technology refused this proposal. Tong Zixian, chairman of Heshuo, said earlier that many suppliers are not interested in building factories in the United States, because the supply chain of the electronics manufacturing industry is huge and complex, and it is very difficult to achieve pure American production.

But now that Foxconn has moved to the United States, many manufacturers in the Apple supplier group may start to feel anxious, which will promote the idea of those wavering manufacturers moving.

Therefore, Foxconn’s investment in the United States has brought great benefits to Apple, because in terms of innovation, if designers, engineers and workshop production employees can gather in the same eco-industrial environment instead of scattered in different countries, close business intersection can enhance their integration and understanding, which can bring greater creativity. Obviously, this is a common dividend between Apple and American manufacturing.

For Foxconn itself, going to the United States to build a factory or completing its industrial upgrading to seek the inevitable road of transformation will help break the brand label of the foundry. Moreover, exporting to domestic market can not only greatly increase Foxconn’s brand premium, but also increase the price and profit of its products.

Trump grabbed Foxconn to build a factory in the United States, but it was difficult to solve the ills of American manufacturing in a short time. On the one hand, the American manufacturing industry has long transferred its production to the third world countries, and only retained R&D and design at home, showing a trend of "de-hard assets". Since the 21st century, the competitiveness of American manufacturing industry has begun to show a downward trend. Nowadays, there are fewer and fewer skilled technical workers in the United States.

On the other hand, the manufacturing industry needs industrial chain clusters, but in the United States, the manufacturing industry has been hollowed out after moving out. Now, if you want to move back and rebuild the manufacturing industry chain clusters, you have lost the talent, technology and industrial chain foundation.

Only relying on political rights can attract the laws of global capital in a short time, but in the long run, the rise and fall of industries and the flow of talents have its long-term economic laws, and capital needs global reproduction and expansion, rather than running around political calls.

For Foxconn, the trouble to set up a factory in the United States is the lack of a large number of skilled industrial workers and supporting facilities for the production of raw materials and parts, and there is no perfect upstream supply chain industrial cluster. It takes time to hire a large number of skilled industrial workers, and the cost rises sharply.

Germany’s Le Monde said that in less than 20 years, factories in the United States disappeared by nearly a quarter. Friedman, a famous American columnist and author of "The World is Flat", once said that the United States is now a small town with 200 start-ups, each of which employs 50 people. It is difficult for the traditional "Made in America" manufacturers to come back.

Therefore, for Foxconn, the most difficult thing is to obtain a large number of skilled workers and related supporting industrial chains, although it may obtain tax incentives provided by local, state and federal governments in the next few years. Industrial agglomeration plays an increasingly important role in manufacturing industry.

On the other hand, the region has little connection with Foxconn’s suppliers and customers and industrial layout, and there is not much reserve of skilled workers, let alone industrial agglomeration, which means that Foxconn is faced with many uncertain risks and has to bear too much infrastructure construction costs.

Because OEM manufacturers like Foxconn need to rely on numerous suppliers’ industrial support to produce, Foxconn will almost start to cultivate talents and develop industrial support in this state, which will drive the development of relevant supply chains in the United States and directly or indirectly bring many employment opportunities. Therefore, in the final analysis, the benefits that Foxconn brings to this state in the United States still far outweigh the benefits that Foxconn has gained.

Therefore, although people know that a profit-oriented enterprise should be counted as an economic account, here at Foxconn, there is also the meaning of political flattery and accommodating people.

Analysts from foreign research institutions have clearly pointed out that Foxconn is trying to avoid the increasing pressure from the US government, which is a political expedient. Because from a commercial point of view, it is not so reasonable to choose to build a factory in the midwest of the United States rather than other regions.

Moreover, it is still a question whether Foxconn’s corporate culture is suitable for Americans, because today, it is difficult for Americans to return to the assembly line and work like blue-collar workers in China, Viet Nam, Southeast Asia and other countries.

Because industrial correlation, demand, environment and industrial ecological correlation are the main driving factors of investment choice. However, Foxconn has not settled this account here. After all, where the depression effect can be generated, where will the money flow? Here at Foxconn, there is obviously a sense of political flattery.

After all, Trump pressured Apple to move the iPhone back to the United States for production. Foxconn needs to hold Apple’s thigh tightly and share the pressure for it in order to win more orders from Apple in the future. In addition, in response to Trump’s new administration’s call for the manufacturing industry to return, it will make some profits, but it will also facilitate Foxconn to go further in the US market and build its brand awareness and influence in the US manufacturing field and internationally.

On the other hand, although the American manufacturing industry itself is declining, it has always been at the top in terms of technology research and development and accumulation and the right to speak in the industrial chain. To become a super giant with upstream and downstream connectivity, Foxconn needs to stand on the basis of American manufacturing and technology research and development. Complete the transformation.

Due to its own manufacturing genes, most employees of Foxconn have long been screws in the product line and rarely participated in upstream research and development. Although Foxconn faces the problem of skilled workers in the United States, it also has the opportunity to attract more cutting-edge scientific and technological talents, participate in the upstream R&D links of American manufacturing, and promote the overall innovation.

But generally speaking, in the modern economy, industrial agglomeration determines the position of manufacturing industry, and there is no integrated industrial related manufacturing cluster in the United States, so Foxconn’s establishment in the United States has mixed advantages and disadvantages, and it is still a gamble. Entering the United States does not mean that you can have global supply capacity. On the contrary, it is prematurely washed away by higher-dimensional industrial science and technology forces due to insufficient innate foundation.

At present, not only Foxconn and Softbank, but also many enterprises are on their way to the United States after the implementation of large tax cuts in the United States. Although they all have a little political contribution, it seems that the collective visit of international manufacturing companies to the United States has become a hot outlet.

For example, Samsung Electronics recently announced that it will invest 380 million US dollars to build a home appliance manufacturing factory in South Carolina. In February this year, Intel announced that it would invest $7 billion in building a semiconductor factory to produce seven-nanometer chips in the next three to four years. In May this year, some media reported that Infosys, a world-renowned software outsourcing giant, announced that it would invest in the United States and create 10,000 jobs. In March 2017, LG Home Appliances will also establish a new factory in the United States.

The collective action of global industrial capital may be based on the demand for optimal allocation of resources on the one hand, and on the other hand, it is based on showing kindness and standing in line with the Trump administration in order to obtain the new government’s policy dividend for manufacturing industry and find a new direction for industrial layout, so that the integration of manufacturing industry into the US market can enhance its international competitiveness and attract better technology and talents.

We know that manufacturing is the foundation of a country’s economy and the guarantee of people’s livelihood and employment stability. This is an important reason why the United States does not hesitate to compete for manufacturing giants with tax, cost and policy concessions on a global scale.

As early as 2016, during the two sessions of the National People’s Congress, Cao Dewang submitted a proposal, saying that the rising labor in China, transportation costs, high industrial land costs, tax burden, resource prices, etc., made the unreasonable cost factors more prominent. On the contrary, China’s neighboring countries with late-developing advantages such as demographic dividend are creating conditions to attract investment.

At present, in the United States, except that labor is higher than that in China, the costs of energy, land, logistics and finance are all lower than those in China. In particular, it is mentioned in the industry that the land price difference between China and the United States is as high as nine times, and the tariff problem in the United States, if you export after manufacturing in the United States, the product price is almost the same, and you can get a higher brand premium. So early layout in the United States is obviously a more cost-effective choice.

It is also an indisputable fact that part of China’s manufacturing investment is flowing to the United States. According to the data of the Ministry of Commerce, by 2015, the manufacturing industry has surpassed the financial industry and become the most important industry for China’s direct investment in the United States. Wang Shouwen, Vice Minister of Commerce, revealed that in 2016, the scale of foreign capital utilization in China is expected to be the same as that in 2015. Compared with the year-on-year growth rate of 6.4% in 2015, China’s attracting foreign investment slowed down significantly last year.

Moreover, the domestic manufacturing industry has always been given the impression of cheap, backward production capacity and low-end sweatshops, which has long been stigmatized. Nowadays, young people in China are increasingly reluctant to flow into the manufacturing industry. Zong Qinghou, chairman of Wahaha, also complained before: the taxes and fees in the real economy are relatively high, the profit rate is very low and it is very hard, and many people are unwilling to work in the real economy.

Many people don’t want to work in the real economy, and the environment of the real economy is not good, which also makes China local and foreign manufacturing investors in China start to weigh and wait and see those countries that release friendship and dividends.

An important reason why the high-end upgrading of domestic manufacturing industry has not been successful is that the profits of manufacturing industry have not been used to invest in high-end technology research and development to complete the transformation from low-end cheap factories to capital-intensive and technology-intensive enterprises, but have been used to participate in shares or flow into real estate and other hot industries.

In current China, it is not clear which industries can replace real estate to drive growth. On the other hand, China’s manufacturing industry is also experiencing the same path as American manufacturing. For example, we can see that many of Shenzhen’s once prosperous clothing and toy factories have moved to Vietnam and other countries with lower costs.

Now, some consumer electronics manufacturers are also moving out. Many enterprises are saying that they will use robots instead of manpower to cut costs, while some enterprises have already replaced machines on the assembly line. At this time, the United States shouted that the manufacturing industry was returning, and Foxconn moved its factory to the United States. In fact, it was a warning to China’s manufacturing industry.

We know that China’s manufacturing industry and the real economy are abnormal in the current environment. It is not that the United States naturally develops to the top and then naturally expands globally to Zhang Zhilu. Instead, when the industrial base and scientific and technological development level of manufacturing industry are still in the development stage, capital, labor and talents are accelerating away from manufacturing industry, and then flow to real estate, Internet industry, financial industry and other fields where money is fast coming, and there is a lack of real respect and attention to the real economy and manufacturing industry.

On the one hand, the United States is vigorously promoting measures to attract outstanding global manufacturing enterprises, while at home, including Samsung, Toshiba, Panasonic and Sony, they are all considering reducing their capital in China and focusing on countries with lower costs.

If the manufacturing industry is marching towards the era of Industry 4.0, but the soil, cost, atmosphere and technical level of China’s manufacturing industry are still not enough to support the development and cost-effective advantages of high-end manufacturing industry, then in the future, more and more outstanding manufacturing entities will run to countries with more dividends. Of course, many international high-end manufacturing entities will not completely abandon China’s manufacturing industry at present, but more and more will tend to focus on both hands and put their eggs in multiple baskets.

Today, with the gradual loss of demographic dividend, the competitive advantage of domestic manufacturing industry and its attraction to foreign investment cannot still rely on lower-cost labor resources. Therefore, what the current manufacturing industry leaves us is not only reflection, but also crisis.

　

　　Land Rover from Britain has always occupied a place in the recreational vehicle market in Europe. However, as the "Rolls-Royce in SUV", there is no doubt that Land Rover pays attention to its interior design. This time, the top models of Land Rover Range Rover will come to report with greater motivation, which is the protagonist of this article, Range Rover Supercharged.

　　

　　Regardless of whether the Land Rover Range Rover in the past was off-road oriented or the later Land Rover Range Rover was luxury oriented, after retaining two fine traditions, since it is called "Land Rover Range Rover Supercharged", this time it must be an SUV with the ultimate performance orientation.

　　The Land Rover Range Rover Supercharged is a 4.2-liter supercharged V8 engine developed by Jaguar Car Factory, which can output 390 horsepower and the maximum torque of 550Nm. Driven by the brand-new ZF six-speed automatic transmission, the Range Rover Supercharged can accelerate from 0 to 100 km/h in about 6 seconds, and the top speed is 225 km/h. Of course, the conversion function of this ZF gearbox can also let the owner experience the shifting pleasure of the handcrafted car. In addition, when encountering the terrain that must be heavily off-road, the automatic slow driving mode can also make the Range Rover Supercharged get out safely.

　

Land Rover Range Rover waded through mountains and rivers.

　　Since we talked about getting out safely, of course, we have to talk about the maneuverability of Range Rover Supercharged. The car body structure design of Range Rover Supercharged is taken from Discovery 3/LR3, another car model owned by Land Rover. Although the wheelbase has been reduced by as much as six inches, the front and rear independent double wishbone suspension with pneumatic suspension has really improved the car body shaking. In addition, through the dynamic feedback system, the car owner can really grasp the road conditions. Therefore, Range Rover Supercharged can not only conquer difficult off-road terrain, but also become a beast that devours the road. However, in order to find out the best setting, the Land Rover team also put Range Rover Supercharged on the famous Nürburgring track for testing. After completing this work, Land Rover also put Range Rover Supercharged on 20-inch shoes, which were equipped with Brembo front brakes with four-point calipers to ensure the braking performance of Range Rover Supercharged.

　

　　As for the interior part, Land Rover certainly didn’t ignore the compliment of "Rolls-Royce in SUV". In order to present the luxurious car room of Range Rover, Land Rover uses a large number of high-grade leather, wooden decorative plates and aluminum alloy as the main materials for interior decoration. The moderate support and softness of the seat bring great comfort to passengers. The button configuration on the center console is also quite neat, and the multi-function steering wheel allows the owner. In addition, the fixed-speed navigation system reduces the burden of long-distance driving, and the use of xenon headlights keeps Range Rover Supercharged in blazing with anger.

On August 2 nd, the second model of Jiyue Automobile was officially unveiled. According to previous reports, the ultra-Yue 07 positioning pure electric medium-sized car is the first car of ultra-Yue Automobile, and it is planned to be listed in the second half of the year. Previously, it has been listed, and the car is positioned as a medium and large SUV with a guide price range of 219,900-309,900 yuan.

In terms of appearance, the Extreme Yue 07 adopts a family-style design style, the front face adopts a closed air intake grille, and the light groups on both sides are connected by U-shaped daytime running lights. The front face of the whole vehicle also has good recognition, and the newly unveiled green appearance color scheme looks very sporty. In addition, the dual lidar is located inside the light groups on both sides of the front bumper. The official said that the new car is equipped with intelligent AI pixel headlights and voice functions inside and outside the car, and it is also equipped with pure visual high-order intelligent driving technology. Extreme Yue 07 designs blue-green high-performance indicator lights in the front, back, left and right directions of the vehicle, which can show the breathing effect when the vehicle is charging and display the charging state of the vehicle externally.

On the side of the car body, the Extreme Yue 07 adopts a sliding back coupe design, and the waistline is straight and sharp and extends to the taillights on both sides. The hatchback coupe body with strong sense of movement creates a feeling of being ready to go. It is worth noting that the rim with low wind resistance is equipped with a small-sized exterior rearview mirror and a hidden door handle, all of which are making efforts to optimize wind resistance. The vehicle has hidden sensors and wipers such as the camera and ultrasonic radar outside the vehicle, and the equipped intelligent induction electric door is designed without a door handle. The door can be opened/closed not only by intelligent induction, voice inside/outside the vehicle, Bluetooth and physical buttons outside the vehicle, but also by stepping on the brake pedal.

In the rear part, the slender through taillights make the rear of the new car have a good sense of science and technology, and the taillights are Y-shaped on both sides to echo the headlight group, and the overall recognition is also relatively high. The tail is equipped with a lifting tail, and the automatic lifting tail will automatically rise when the vehicle speed is above 95 km/h, helping the vehicle to enhance the downforce. The automatic lifting tail will automatically lift when the vehicle is unlocked and retract when the vehicle is locked, and it can also be controlled manually.

In terms of size, the length, width and height of the polar cross 07 are 4963/1989/1475mm and the wheelbase is 3013mm, respectively. In contrast, the length, width and height of Krypton 007 of the same class are 4865/1900/1450mm, and the wheelbase is 2928 mm. The overall size of Krypton 007 is larger.

As for the interior, the Extreme Yue 07 adopts the family-style design style and is equipped with a 35.6-inch 6K penetrating large screen, in which all the entertainment functions such as dashboard, central control and co-pilot are integrated in the screen, which can be displayed in dual-screen, triple-screen and full-screen. At the same time, the Extreme Yue 07 is also equipped with a U-shaped half-width steering wheel, so the physical keys are simplified to the greatest extent, and the traditional left and right levers are cancelled, which is consistent with the new model. The sub-instrument panel of Extreme Yue 07 is connected. There are two wireless charging panels for mobile phones in the front row, which support active ventilation and heat dissipation. There is a shift button below, and a cup holder with a cover plate and storage space are also provided. In addition, the two sides of the Extreme Yue 07 center console are also equipped with a lifting sound system, a panoramic canopy, a control screen in the back row, an air conditioning outlet, and a central armrest.

As for the power, refer to the application information. The Extreme Yue 07 is built on the vast structure of Geely SEA, equipped with motors provided by Weirui Electric Vehicle Technology (Ningbo) Co., Ltd., with dual motors for high-end models and single motors for standard models, with a peak power of 200 kW. In terms of batteries, the Extreme Yue 07 is equipped with 71.4 kWh and 100 kWh battery packs, of which the 71.4 kWh battery model has a pure electric cruising range of 660 kilometers, and the 100 kWh battery model has a pure electric cruising range of 770 kilometers (four-wheel drive) and 880 kilometers (rear drive).

Jiyue Automobile, formerly known as Jidu Automobile, was jointly established by Baidu and Geely. In January 2021, Baidu announced that it would build a car, saying that it would formally set up a smart car company to enter the automobile industry as a vehicle manufacturer, and Geely was the strategic partner of the new company. Two months later, Jidu Automobile, initiated by Baidu and strategically invested by Geely, was officially born. With the help of Geely, the speed of Jidu automobile is extremely fast. In June 2022, Jidu ROBO-01 concept car came out.

Regarding the sales target of Jidu Automobile, Xia Yiping, CEO of Jidu Automobile, once said: "My goal is to sell 10,000 units every month. There is really no need to worry about building a car now, but it doesn’t mean that you can sell it if you build it. " In addition, Xia Yiping also revealed that "in 2028, Jiji will have the ability to deliver 800,000 car robots throughout the year". However, the reality is very skinny. Due to the lack of production qualification, Jidu Automobile cannot directly entrust Geely to produce it. In the end, Baidu and Geely officially announced the brand of "Extreme Yue Automobile" in August 2023, and the first model was named "Extreme Yue 01". At this time, Baidu had to hand over the leading power and choose to participate in the car building as a technical solution provider to ensure that the ultra-Yue car can be mass-produced smoothly, and the ultra-Yue car has officially become a sub-brand of Geely. In October 2023, Extreme Yue 01 was officially listed at a price of 249,900-339,900 yuan. In November, 2023, the official price of Chaoyue 01 was reduced by 30,000 yuan, and the price range after the price reduction was 219,900-309,900 yuan.

Although it is backed by Geely and Baidu, the sales of Extreme Yue cars are very poor. In the first half of the year, the sales volume of Extreme Yue cars was only 2,700, and the monthly sales volume was less than 500. The sales volume was so bad that it could not be described as "depressed".

Extreme Yue 07 is the first car owned by Extreme Yue Automobile and the second model owned by Extreme Yue Automobile. It was officially named in December 2023, and it was also declared in the Ministry of Industry and Information Technology, but it has not yet been listed. As a pure electric medium-sized car, the competitors of Extreme Yue 07 will aim at Tesla Model 3, Extreme Krypton 007, Extreme Krypton 007, Extreme Yue 007, Extreme Yue 07, and Lingke Z01. In the first half of the year, the best-selling pure electric medium-sized car was Tesla Model 3, with 70,500 cars, Xiaomi SU7 with 30,000 cars, and Extreme Krypton 007 with 27,200 cars. Referring to the market positioning and competing products, it is estimated that the market price of Extreme Yue 07 should be in the early 200,000 yuan.

Many friends know that the engine oil needs to be changed when the vehicle is maintained, but many people don’t know what the function of engine oil is and how to choose engine oil. Today, Xiao Jia will introduce you to the knowledge about engine oil!

Automobile lubricating oil can be generally divided into three types because of its different functions: engine oil, gearbox and differential oil, and grease (butter). The most common thing in vehicle maintenance is to change the engine oil.

Engine oil has five functions.

Lubrication function: the function of engine oil is to fill and lubricate the surfaces of moving parts and reduce the friction between moving parts. Its working principle is: the engine oil is pressurized by the oil pump and transported between the rotating parts, and an oil film is formed on the two friction surfaces to separate them, thus reducing the contact surface between moving parts, thus reducing wear and prolonging the service life of parts. There is surface friction between piston and cylinder, crank-connecting rod mechanism, cam valve train, gear rotating mechanism, etc., which must be lubricated by engine oil to ensure normal working conditions.

Cooling function: engine oil can bring back part of the heat generated between the rotating parts of the engine to the oil pan, and achieve the cooling effect through the oil pan wall. Some engines are also equipped with special engine oil radiators to achieve better cooling effect, so as to ensure the normal temperature between the rotating parts of the engine and keep the engine in normal working condition for a long time.

Sealing function: The engine oil also has a sealing function. For example, the engine piston ring and the cylinder wall are filled with engine oil, so that the contact surface and the gap have both a lubricating function and a sealing function, so that the piston can reduce air leakage when inhaling and compressing, and ensure the normal working compression ratio. If the piston ring and cylinder wall are worn, the sealing effect of engine oil can be improved by adjusting the viscosity of engine oil or adding engine oil additives, thus improving the working condition of the engine.

Cleaning function: The engine oil is pressurized by the oil pump and transported between the rotating parts of various parts for lubrication and heat dissipation. At the same time, it can also wash and clean the rotating working surface of the parts, bring the dust particles entering the engine and the garbage generated by the work to the oil pan, and keep the engine parts, rotating working surface and oil passage clean and smooth through the oil collection net and oil filter, thus ensuring the normal operation of the engine.

Rust-proof function: The working environment of the engine is complicated, and the climate change in spring, summer, autumn and winter will easily cause the metal parts to rust and deform, which will affect the normal operation of the engine and shorten its service life. The oil is pressurized by the oil pump and supplied to all parts and metal surfaces through the oil passage to form an oil film to isolate the air, which can prevent the metal surface from oxidation and rust and improve the service life of the engine.

If the engine is likened to the heart of a car, then the engine oil is the blood of the engine, which is a necessary condition to ensure the normal operation of the engine. Understanding the knowledge of engine oil, correctly selecting and using engine oil, and regularly replacing and maintaining it are very important to ensure the normal operation of the engine and prolong its service life.

　　[Global Times Comprehensive Report] German Chancellor Angela Scholz visited the White House on the 3rd local time to hold talks with US President Biden. The visit was not accompanied by any media, business delegations and cabinet ministers, and no joint press conference was held after the talks between the two sides. The media have questioned what is hidden behind this "mysterious visit". Some analysts believe that Germany and Germany are full of contradictions on issues such as aid to Ukrainian tanks, the explosion of the "Beixi" natural gas pipeline and the US Inflation Reduction Act, which is full of protectionism. However, as the "younger brother" of the United States, German leaders can do nothing about it. Germany’s "Star" magazine recently published a cover article saying that "Big Brother is back". The cover cartoon shows Biden holding Scholz, who is only half as tall, while the latter looks up at Big Brother.

　　Leave it to the public for only four minutes

　　"Mysterious visit", DPA said on the 4th that Scholz held talks with Biden at the White House on Friday, but this meeting only gave the public four minutes to observe. In his public appearance before the talks, Scholz said in English, "I really appreciate the good cooperation between us" and the transatlantic partnership is "in a very good state". Biden praised Scholz’s "strong leadership" and support for Ukraine, and said that the two countries would "help Ukraine with Qi Xin" and "keep pace in all aspects".

　　Then the two began to talk behind closed doors. The report questioned that the talks were "too mysterious". There were no consultants and recordings for the talks between the two sides, and there was no joint press conference after the talks. The report also complained that Biden ignored Berlin in his previous "trip to Europe". Biden visited Ukraine and Poland a few days ago and only made a short stop at Ramstein Air Force Base in Germany. On the contrary, this is Scholz’s second visit to Washington since he took office.

　　The Associated Press quoted people familiar with the matter as saying that the meeting between Biden and Scholz lasted for more than an hour, and the focus of the discussion was to continue to promote "global assistance to Ukraine". However, even Scholz’s senior advisers were not allowed to attend the talks. When their talks ended, Biden said half jokingly that they "solved all the problems in the world". However, the official statement issued by the two countries after the meeting hardly provided more details of the talks, and did not disclose any possible agreements or plans.

　　The secret visit and talks angered the German opposition. German CDU leader Mertz questioned in an interview with "German Editorial Network" on the 4th: "No one in our parliament and the German public knows the contents of this visit." He accused Scholz of keeping his Washington trip secret, which was "unconventional".

　　The New York Times said that there is growing opposition in the United States and Germany to aid Ukraine, and Scholz and Biden are also facing the upcoming general election (German parliamentary elections will be held in 2025). Jens, a senior researcher at the German Marshall Foundation, said that in terms of the long-term sustainability of political support, both of them face great resistance. For domestic political purposes, they need each other.

　　German-American relations are frequently questioned.

　　Although Biden called virtue "in step with all aspects", many analysts believe that there are many practical contradictions between virtues on many issues. CNN said that in the two countries, the voice against providing military assistance to Kiev is becoming louder and louder. Therefore, although the two sides announced that they would provide main battle tanks to Ukraine, they still shirked the relevant details. Not long ago, Sullivan, Assistant to the President of the United States for National Security Affairs, claimed that the United States agreed to deliver M1 main battle tanks to Ukraine under the "hard pressure" of Germany. The American statement angered Germany. The german government immediately refuted the us statement. At the Munich security conference not long ago, German Defense Minister pistorius complained without name that "some countries prefer to hide behind Germany" when it comes to tank aid.

　　The explosion of the Russian-European "Beixi" natural gas pipeline in September last year is another point of disagreement between the United States and Germany. Before Scholz’s visit to the United States, a number of German lawmakers demanded that Scholz should take tough words against the United States when meeting Biden. However, judging from the public information, the talks did not mention the "Beixi" incident. "Russia Today" TV station said that the German government remained silent half a year after the incident. "The vassal position of the United States does not allow Berlin to talk about who is behind the scenes, and Germany’s foreign policy is completely locked in the track of Washington", which will make "Germany’s future into a dead end".

　　In addition, Biden signed the "Inflation Reduction Act" last year, and its protectionist provisions dealt a serious blow to the automobile industry in Germany and other European countries. Agence France-Presse said that Germany-US relations are relatively close (closer than France-US relations) because of its heavy dependence on NATO and US military protection. But in fact, relations between the two countries have fluctuated recently. For example, the US Inflation Reduction Act heavily subsidized the green industry, which triggered a strong rebound in Germany, but was ignored by Washington.

　　Before the talks, White House officials said that the China issue was also one of the topics of the talks. However, during this visit, Scholz avoided the topic of China. "Deutsche Welle" said that Germany is still waiting to see that China is Germany’s most important trading partner, and the idea of losing business in China will "cause German manufacturers to worry about their survival".

　　"Big Brother is back."

　　Tsargrad TV station in Russia said that at present, the political and military prestige of the West is in jeopardy, and the Western people are increasingly dissatisfied with the government’s practice of arching fire. Due to lack of confidence in France, Britain’s economic situation is difficult and it is no longer a member of the European Union. The United States hopes that Germany will play a key role in mobilizing the European Union against Russia and China. According to the report, judging from the brief press release issued by the two sides after the talks, Scholz showed its "loyalty to Washington as a vassal country. Americans know how to treat weak politicians and obedient countries. "

　　"Big Brother is back", the cover article of the latest issue of German "Star" magazine reported on this topic. For Scholz, "Fortunately, there is Biden — — We can count on the United States again in the conflicts with Russia and China. ".

　　Volodin, chairman of the Russian State Duma (lower house of parliament), wrote on social media on the same day, according to a report by RIA Novosti on the 5th: "The United States once again shows that its basic policy principle is to use other countries to realize its own interests. The United States forced European countries to support the Kiev regime at the expense of their citizens’ welfare, but their own expenses were much less than those of other countries. " He said that the United States spent only 0.37% of its GDP on supporting Ukraine, while Poland spent 2.1% of its GDP. In addition, EU countries have paid an extra price for anti-Russian sanctions, which has affected the national economy. The loss of energy in European countries is about 570 billion euros, and the loss in Germany accounts for 7.2% of GDP.

　　In recent years, "big data" has gradually moved from academic concept to industrial application, and has become the "window" for the Internet industry to compete for each other. However, although there are endless ideas, research and plans about big data in the industry, most companies have not actually enjoyed the change dividend brought by big data.

　　Nowadays, with the maturity of face recognition, artificial intelligence, cloud computing and other technologies, big data applications have also landed and begun to reshape existing business models.

　　Fashion can also be customized.

　　The favorite color of young people born after 1995 in China is "unsaturated black" with RGB value of 22/20/24. When buying clothes, the colors they most often match with black are "red, yellow and blue". The favorite clothing materials are cotton, wool and leather, and the favorite colors are printing, graffiti and letters … …

　　The above conclusions come from the "China Post-90s Fashion Color Report" jointly released by Tencent and e-commerce platform Vipshop. Relying on Tencent’s AI (artificial intelligence) face recognition and image processing technology, based on Tencent’s QQ space 2 trillion social media photos and Vipshop’s 100 million e-commerce users’ sales data, the two companies jointly "calculated" China’s "post-1995" dressing preferences.

　　It is not easy to extract the "fashion factor" from 2 trillion photos and 100 million e-commerce user data. According to Liang Zhu, vice president of Tencent Group and head of Youtu Lab, finding these popular colors needs to overcome many technical difficulties. For example, the photos uploaded by users in QQ space are mainly life photos, and the background and colors are very complicated. In order to achieve accurate color acquisition, its technical team uses many artificial intelligence algorithms, including human body detection and clothes segmentation, to separate the human body and clothes in the photos from the background, and its pixel segmentation accuracy reaches 95%.

　　It is understood that the two companies jointly invited designers to design fashion clothes based on the calculation results, and plan to sell them online on the Vipshop e-commerce platform this fall.

　　"Face recognition and image processing technology based on machine learning has always been a hot technology in the future, and its application range is very wide. At present, Tencent Youtu’s AI image recognition technology is very mature and can be applied in different scenarios. " Beam-column representation.

　　No longer "looking at the number and sighing"

　　In the past, big data applications were mostly confined to the marketing level. Its essence was to use the advantages of "big data" to analyze market factors such as user behavior by traditional computing methods, which was not a real big data application. In the face of massive and precious data, it is often impossible to really use it, and it can only be "sighing and sighing".

　　Nowadays, the application of big data has broken through the limitations of data capture and statistical methods in the past, and has begun to penetrate into all aspects of the industrial chain, becoming a "closed-loop ecology" that runs through big data.

　　In the retail field, following the concept of "new retail" put forward by Alibaba last year, at the beginning of the new year, Alibaba Group signed a comprehensive strategic cooperation agreement with Bailian Group, announcing the joint efforts to explore and develop a new retail model. According to Ali, based on big data and Internet technology, the two sides will cooperate in six areas: all-format integration and innovation, new retail technology research and development, supply chain integration, member system interoperability, payment financial interconnection and logistics system coordination.

　　"The new retail is to use the Internet and big data to ‘ People, goods and fields ’ And other traditional business elements, including the reconstruction of production processes, the reconstruction of the relationship between merchants and consumers, and the reconstruction of consumer experience. In the future, business will no longer be divided into online and offline, and there will be no difference between virtual entities. " Zhang Yong, CEO of Alibaba Group said.

　　In the field of household appliances, according to the newly released White Paper on Smart Air Conditioning Market in China in 2016, the domestic smart air conditioning industry has been improved in manufacturing, channels, services, resources and application level of new technologies in 2016, especially the introduction and resource sharing of cloud and big data technology, which has laid a solid foundation for resource sharing and service innovation in related industries.

　　Take Haier, a home appliance company, as an example. Relying on big data, the air conditioners produced by Haier not only built an intelligent energy-saving system, but also applied big data to the fields of heating and power supply. In Jiangsu, Haier’s air-conditioning cloud data has been effectively connected with the State Grid, so as to adjust the peak power load of residents, reduce the peak-valley difference of the grid by 18.47%, and greatly ease the operating pressure of the grid.

　　Realize "personalized mass production"

　　In fact, the continuous application of big data is solving the contradiction between "personalization" and "mass production" in the past, which has brought about changes in business models.

　　In the past, mass-produced products could hardly meet the individual needs of customers. Even with massive data as the marketing basis, we could only subdivide the needs of users as much as possible, and then mass-produce in each subdivision. With the penetration of Internet, big data, cloud planning and other technologies, it is possible to meet personalized and customized needs, and personalized mass production is being tried and explored. According to Chen Feifei, senior director of Vipshop, it is a bold cross-border innovation to apply big data to the fashion industry and conduct e-commerce operation. "Let photo big data, sales big data, artificial intelligence collide with fashion trends, connect data with art, and provide more inspiration and possibilities for creation in the fashion field." Chen Feifei said.

　　This attempt has brought obvious changes to the production mode of fashion industry, that is, from the former designer-led mode to the user-centered personalized mass production mode. Consumption data will become the most valuable resource in the fashion industry ecological chain. Whoever has more accurate user data will have more market opportunities.

　　Similarly, in the field of household appliances, Haier air conditioning can simulate 30 body parts, 20 metabolic modes, 162 neuron sensors and 17 warm and cold environments through joint research and development of intelligent bionic human technology. At the same time, relying on bionic people, we have developed original technologies and products such as natural wind, self-cleaning and ion air supply to realize personalized energy saving for thousands of people and make every air conditioner produced in batches "different".

　　In the field of medical and health care, because of the different disease history and genetic composition of each person, the standardized treatment scheme for diseases in the past is more like a "stopgap measure" under technical restrictions. Nowadays, with the breakthrough of medical sensors, monitors and diagnostic technologies, patient data has become complete and detailed. On this basis, the artificial intelligence system can comb the medical records, genome sequences and other health behavior data of millions of patients, so as to match the personalized treatment plan.

　　Various trends show that this change in business model is rapidly infiltrating into various industries. The universal landing of "personalized mass production" will also be possible with the support of big data.
