The domestic shield machine is new again!

On September 27th, the "Jinghua" extra-large diameter shield machine rolled off the assembly line in Changsha. This shield machine is 150 meters long, with a total weight of 4,300 tons and a maximum excavation diameter of 16.07 meters. This is the largest diameter shield machine developed in China so far, and it will participate in the reconstruction project of Beijing East Sixth Ring Road after leaving the factory.

The equipment was jointly developed by China Railway Construction Heavy Industry Group and China Railway 14th Bureau Group, and it was the first time that Chinese enterprises successfully realized the industrial manufacture of 16m-class super-large diameter shield machine. The reporter saw at the scene that the equipment was huge, like a steel giant lying workshop, with a height of more than 5 floors. The cutter head painting extracted visual elements from Peking Opera masks, and took the red masks representing loyalty, courage and righteousness in Peking Opera as the design prototype. The appearance was bright and eye-catching, highlighting the regional cultural characteristics of Beijing.

Many netizens saw it and called this Facebook "absolutely"!

In fact, the painting of Beijing Opera theme of "Jinghua" is not the first case.

China shield machine has excellent performance, and its "skin" is also very distinctive.

China exports Russian money ("Victory"):

Behind every "new skin" is the story of China people’s struggle to break the blockade and monopoly.

Shield machine, also known as tunnel boring machine, was invented and used in foreign countries as early as 1825.

Due to the difficulty in manufacturing, the shield machine market has been occupied by Germany, the United States and Japan for a long time.

Developed countries monopolize technology and market, and buyers have no bargaining power.

"Spending money depends on your face", and China at that time was no exception.

In 1997, when China was building the Qinling Tunnel of Xikang Railway, the first tunneling equipment was introduced from Wilt Company of Germany.

When I bought two machines, that was 700 million.

It was 700 million yuan in the 1990s, and people’s attitude was like that: Love buy buy, don’t buy it.

Tan Shunhui of China Railway Engineering Equipment Group recalled this past event and said that at that time, the right to speak about the price was in the hands of foreigners. He said that the money was as much as he wanted. If you want to make any changes, you should add the price first.

Because foreign countries have occupied the highest point in technology, their arrogance of looking down at people is the most unacceptable and uncomfortable.

The "after-sales service" of foreign experts is also very expensive, with an hourly salary of 600 to 800 euros.

Besides, when to repair it depends on people’s work schedule and mood.

In this way, foreign experts have to set up a cordon to prevent China people from watching.

In 2001, the foreign side proposed that an old shield machine should be sold at the price of a new shield, and the accessories should be increased by 100%.

In their view, China people can’t make it themselves, and they will accept the harsh conditions.

Generations of China people are fighting in their hearts: "We must use our own equipment in the future."

No matter how hard and bitter it is, we must build our machine!

Starting from the design drawings, China began to explore his own shield machine under the background of inexperience.

Really, start from scratch.

Follow suit, the shape is there, but it is still far from "domestic".

Li Jianbin of China Railway Industry said: "If you really do it yourself, you will know how difficult it is to manufacture the key components."

For example, knives, how many knives are arranged? What is the height? What is the spacing between knives? What is the opening rate of the cutter head?

China people don’t know these things, so they have to start from scratch and conduct theoretical research.

In actual work, the machine may encounter granite and limestone; May face hard soil, soft soil, silt, silty clay … These all need different tools according to different geology to make the best design.

It took China nearly five years to figure out the problem of cutting tools.

Under such difficulty, China people just chewed this bone down.

In 2008, China’s first shield machine with independent intellectual property rights was successfully rolled off the assembly line.

In 2013, the "Big Brother" German Wilt Company was acquired by China Railway Equipment.

Nowadays, the domestic shield machine has broken the monopoly of foreign technology and market, and lowered the price of similar products by 40%.

Domestic shield machines have also reached the top in many fields, with innovations: the world’s first horseshoe shield, the world’s largest rectangular shield, the world’s first inclined shaft dual-mode TBM, and the world’s first permanent magnet motor-driven shield machine …

Being "stuck in the neck" Sorry, now it’s: "No one has me, and everyone has me."

Not only the technology is good, but also many styles, large output and low price.

"There is a Shenzhou in the sky, a dragon in the sea, and a shield in the ground", and "a great country’s weapon" is both a starting point and a monument.

Like for Hunan manufacturing!

Whether it is a pure oil vehicle or a new energy vehicle, "cost performance" is always the three words that users often say. Unlike pure oil vehicles, many users pay more attention to cruising range, intelligence, functional configuration and, of course, price when choosing new energy vehicles! Jiyue Automobile is a car brand jointly created by Geely and Baidu. Geely is responsible for manufacturing and chassis control and adjustment. Baidu, as an Internet company, is naturally responsible for the intelligent section. The division of labor is clear, and the cars jointly manufactured will naturally not be bad. It is the first car product of Jiyue brand, with a price of 199,900, which is attractive. Without further ado, in this issue, we will interpret the configuration of Extreme Yue 07 to see why it is cost-effective.

Since it is a new energy pure electric vehicle, intelligence is the natural focus! Different from other brand models, Extreme Yue 07 comes standard with ASD Apollo high-order intelligent driving based on Baidu Apollo L4 autopilot from the beginning of the entry-level model, and comes standard with high-precision maps and navigation assistance functions on high-speed sections. After setting the driving route, automatic driving can be started, which reduces the driving difficulty to some extent. In terms of hardware, the Extreme Yue 07 comes standard with two NVIDIA Orin-X chips and 34 sensing hardware, which makes the vehicle behave more calmly in the face of complex road conditions.

In terms of power, Extreme Yue 07 has two power versions: single motor and double motor.Standard editionandLong battery life versionThe maximum power of the rear single motor is 200kW(272Ps) and the maximum torque is 343N·m, which is enough to compare with the mainstream models. The standard version provides 71.4kWh, and CLTC has a pure battery life of 660km；; The long battery life version provides 100kWh, and the CLTC pure electric cruising range is 880km. Both the standard version and the long-life version support 400V high-voltage fast charging, effectively shortening the recharge time. Of course, if performance is more important, you can consider starting.Performance editionModel, the combined maximum power of front and rear dual motors is 530kW(721Ps), the maximum torque is 653N·m, plus the four-wheel drive system, the official nominal acceleration time is 0-100 km/h.3.5 seconds. In addition, the power battery used in the performance model is 93.4kWh from Contemporary Amperex Technology Co., Limited, which supports800VHigh-voltage fast charging, CLTC pure electric cruising range of 770km. The power batteries used in the standard version, long-life version and performance version all provide unlimited mileage/life warranty, which reduces the worries of car owners.

In terms of chassis, the Extreme Yue 07 uses the front double wishbone/rear structure, and is also equipped with CDC dynamic chassis adjustment, which gives the chassis a high integrity and will not make the passengers in the car feel loose when taking bad roads. When cornering at a faster speed, the suspension can give better support to the car body, effectively restrain the rolling action of the vehicle and give the driver confidence. Through the camera outside the vehicle, the visual field around the vehicle can be displayed on the dashboard, which brings convenience to driving in rainy days and can give the driver a clearer visual field.

Why do you say that Extreme Vietnam 07 is cost-effective? In my opinion, this Extreme Yue 07 is equipped with more high-end functions. The whole system comes standard with ASD Apollo high-order intelligent driving based on Baidu Apollo L4 autopilot, equipped with high-precision maps, and supports high-voltage fast charging. These functional configurations may only be available on competing models of the same level and price, but the Extreme Yue 07 is all made as standard, and users don’t need to spend extra money on matching. In addition, the power battery provides unlimited years/mileage warranty. For a pure electric new energy vehicle, the power battery is the core part, which will make users feel more at ease in the future use process. Powerful functional configuration and reasonable price make the price/performance ratio naturally high! What else do friends in front of the screen want to ask about this ultra-crossover 07? Please leave us a message in the comment area.

　　Municipal social governance is an important part of national governance. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has attached great importance to the work of regional social governance, and has held a series of important meetings, such as the Central Urbanization Work Conference and the Central Urban Work Conference, to put forward clear requirements and make strategic arrangements for related work. After the Fourth Plenary Session of the 19th CPC Central Committee proposed "accelerating the modernization of regional social governance", the Fifth Plenary Session of the 19th CPC Central Committee further proposed "strengthening and innovating regional social governance and promoting the modernization of regional social governance", which highlighted the importance and urgency of the modernization of regional governance. Effective regional social governance will sink all kinds of resources to the grassroots level, which will not only provide better accurate and refined services for urban residents, but also discover all kinds of potential risks in time and solve contradictions at the grassroots level. To promote the modernization of regional social governance, we can focus on the following four aspects.

　　Constructing party building to lead a new pattern.The Communist Party of China (CPC)’s leadership is the most essential feature of Socialism with Chinese characteristics and the greatest advantage of the Socialism with Chinese characteristics system. Urban grass-roots party organizations are the leaders of the regional social governance system and the practitioners of improving the regional social governance capacity. To promote the modernization of regional social governance, we must build a new pattern of party building leading. With the rapid development of economy and society, the relationship between social interests is becoming more and more complicated, the social class structure is divided, social contradictions and problems are intertwined, and the situation and environment faced by social governance are more complicated. This urgently requires urban grassroots party organizations to effectively coordinate the interests of different departments, industries and groups, improve the level of urban construction, management and service, and constantly strengthen and innovate social governance. To lead the city’s social governance, Party building must first highlight political guidance, effectively integrate the party and government organs, enterprises and institutions, non-public economic organizations and social organizations within its jurisdiction, mobilize all kinds of forces and resources to participate in social governance to the maximum extent, and give full play to the party’s core role of commanding the overall situation and coordinating all parties. In addition, the party building should constantly improve the working mechanism to lead the municipal social governance, and ensure the effective operation of the governance model of up-and-down linkage and co-construction from the system. Under the leadership of the Party organization, regional governance, departmental governance, industry governance and unit governance are organically combined through institutional innovation, and the synergy of government, market and society in social governance is brought into play, forming a multi-participation, interactive and complementary social governance synergy.

　　Adhere to the people as the center.People’s cities are built by the people and people’s cities are for the people. To promote the modernization of regional social governance, we must implement the people-centered development concept. The core of the city is people, which determines that the social governance of the city should start from meeting the needs of people’s better life. As Socialism with Chinese characteristics enters a new era, urban residents need a better life more and more urgently, which not only puts forward higher requirements for material and cultural life, but also sets higher and higher standards for democracy, rule of law, security and environment, which poses new tasks and challenges for social governance. Municipal social governance should concentrate on doing a good job in people’s livelihood, do practical things, do good things and solve difficult problems for the people with greater efforts, and effectively enhance the sense of acquisition, happiness and security of urban residents. The people are the most active and energetic factors in social governance. Municipal social governance is not a "one-man show" by the party and the government, but it is necessary to give full play to the autonomy, enthusiasm and creativity of urban residents, and rely on the wisdom and strength of the broad masses of the people to build a social governance community that everyone is responsible, everyone is responsible and everyone enjoys. In the final analysis, the effect of urban social governance depends on the satisfaction of urban residents. At present, there are still many shortcomings and weaknesses in social governance. Whether these problems can be solved well is related to the attractiveness, creativity and competitiveness of the city. This requires grass-roots party organizations to play a good role as battle bastions, make good use of resources and strength in all aspects, and constantly improve the level of service and management, so that the effectiveness of social governance can benefit urban residents more, better and more fairly.

　　Strengthen systematic thinking.Adhering to the concept of system is a principle that must be followed in the economic and social development during the 14 th Five-Year Plan period. Urban social governance is a comprehensive systematic project, and it is also necessary to strengthen systematic thinking, scientifically grasp the laws and characteristics of social governance, pay attention to starting from the whole and the overall situation, and improve overall planning ability. Specifically, it is necessary to comprehensively and accurately understand the connotation and extension of regional social governance, plan regional social governance in the big chess game of national governance, and at the same time pay attention to the mutual cooperation and joint efforts with provincial governance and county governance to truly form the integrated effect of regional social governance. From the perspective of governance subjects, municipal social governance is the cooperative governance of multiple social subjects within the city, that is, under the leadership of the party, the benign interaction of the government, social organizations, citizens and all parties, in order to promote the coordinated operation of society. From the perspective of governance objectives, the goal of regional social governance is to prevent risks, resolve contradictions and solve problems, and ultimately promote the harmonious development of regional society and ensure social stability and order. From the perspective of governance mechanism, municipal social governance should organically integrate the social governance system of party Committee leadership, government responsibility, democratic consultation, social coordination, public participation, legal protection and scientific and technological support, form a municipal social governance mechanism of joint governance of problems, joint work and joint creation of peace, and create a "systematic" governance model. Strengthening systematic thinking in regional social governance is to organically unify governance subjects, governance objectives and governance mechanisms, so that multiple social subjects can do their best and develop their strengths.Stimulate social creativity to the greatest extent, thus forming the overall synergy of social governance.

　　Promote technology empowerment.The vigorous development of various new technologies, represented by new information technologies, provides new opportunities and new kinetic energy for innovative social governance. On the one hand, the use of modern technology and information technology such as big data, cloud computing, artificial intelligence and blockchain can make the process of social governance more intelligent and scientific, which not only improves the operational efficiency of urban governance, but also provides technical support and support for regional social governance. On the other hand, promoting information infrastructure connectivity, network smoothness, platform connectivity and data integration can enhance the scientific decision-making of regional social governance and improve the accuracy of forecasting and early warning and risk prevention and control. Promoting technology-enabled social governance is conducive to deepening the understanding of the regularity of social operation in the city. By creating modern, networked, information-based and professional social governance, science and technology can better serve the better life of urban residents in the process of realizing the "14 th Five-Year Plan" and the long-term goal in 2035.

　　Let’s talk about something that was heatedly debated by "people with a heart" last week: On August 3, 2016, Latin-NCAP, a Latin American testing center, announced the latest automobile test results, and the models of companies such as,,, and were on the list.

　　

Latin-NCAP "sporadic" models over the years

　　The test was nothing, but the problem is that this time, the "sporadic" models were released, and a small one made a lot of noise because of "no problem".

　　This car doesn’t have it?

　　Seeing this, are you as shocked as Xiaobian? Safety has always been the priority, but this time, it’s against the world to produce this kind of car without it. What is it?

　　Here is a key word: "national conditions", not the national conditions of our country, but the national conditions of Latin America. Due to the differences in economic development in Latin America, the requirements for vehicles will be different according to the degree of economic development, especially in economically underdeveloped areas, and affordable models are the people’s dishes. After all, not everyone runs like everyone in our country. After comprehensively considering economic and consumption factors, governments in Latin America naturally have different market access standards. Except for more developed economies such as Brazil and Chile, the automobile industry in other Latin American countries can be said to be quite backward, and for most Latin American countries, automobiles are not included in the necessary vehicle configuration.

　　

　　This is a very normal thing. If I still don’t understand it, let me explain it from another angle: For example, in India, due to the narrow land and large population, in order to minimize the area occupied by cars, cars in India can even have no rearview mirror, even if some are installed by Indian owners themselves; Also, P is a mandatory standard configuration in the EU, but in our country? Only hehe.

　　

Indian cars without rearview mirrors

　　Therefore, it is not surprising that Latin-NCAP in Latin America has no or sporadic results, not to mention that in Latin America, many other well-known foreign automobile brands, such as,,,,,, etc., have also introduced models without equipment according to local demand, and many of these models have only sporadic results. In fact, it is a product developed to meet such market demand. Moreover, Latin-NCAP’s testing organization specially purchased the lowest-equipped vehicles in a Latin American country, and then conducted tests to draw sporadic conclusions.

　　

　　Is it safe by China standards?

　　Of course, a lot has been said before, and it is always based on other people’s laws and regulations. Apart from being deliberately publicized by some "people with a will", it has almost no reference value. After all, an area with a backward economy than our country, why should we agree with your laws and regulations? It is better to look back at the models in our country, at least more convincing than the tests in Latin America.

　　As I said at the beginning of the article, it’s a brand that I’ve always paid attention to, and I don’t even need to prove it deliberately. Baidu’s search is full of "high-speed crashes, but the owners are unscathed."

The highway is interspersed with guardrails, and the owner is unscathed.

　　It is not a fluke to have this level of strength. As early as 2004, it invested 200 million yuan to set up a laboratory, making it one of the few in China that has the ability to test and evaluate various laws and regulations in China, Europe, the United States and other countries and regions. In 2013, it was awarded the 2013 "Best Laboratory of the Year" award by AI (International Journal of Automotive Testing Technology), which defeated well-known companies such as American companies, IAV Gifhorn of Germany and Thatcham of Britain.

　　Won the "Best Laboratory of the Year" award in 2013.

　　

　　The investment of huge expenses is in exchange for a substantial increase in strength. On December 29, 2011, it was awarded a safety rating, breaking the history that China did not have; On September 7, 2013, it won the safety evaluation with a high score of 56.5, and set a new record of 56.3 for its own brand. On June 29, 2015, it won the safety certification with an excellent score of 57 points, surpassing the same batch of tests and becoming the highest safety in China; On July 1st, 2016, Adison scored 58.0 points (out of 61 points, it must be greater than or equal to 54 points), surpassing the joint venture models such as this batch,, and the last batch.

　　

　　Let’s talk about a very realistic thing. Over the years, we have been developing different products according to the needs of local markets, and the reputation of national brands overseas is also quite loud. In 2013, it has been brought to Brazil, and a bus factory has been established there. More importantly, the official partner of the Brazilian Olympic Games, Brazil Post, adopted the pure electric logistics vehicle T3 in its postal logistics business. Up to now, the footprint of pure electric buses has spread to more than 20 cities in Brazil. In addition to the electric bus factory, the solar energy factory in Brazil will also be put into operation in the near future. In other words, if the safety performance is really as bad as Latin-NCAP said, then why can we achieve such excellent results overseas? Foreigners are not stupid ~

　　If you like cars, want to, or have any questions, please pay attention to the WeChat WeChat official account: kuaichebao of Express.

　　We will push fresh and interesting comments on WeChat every day for everyone to read, so that your car-loving heart can’t stop.

In 2017, Volvo brought S90 and XC60 products, which have been the main sales force of Volvo for five years. Although it is often necessary to attract users with huge discounts, in terms of sales volume, relying on these two main models, Volvo’s performance in the past five years can be described as brilliant. However, as the product strength became more and more old, Volvo’s sales began to decline, and it was time for Volvo to innovate.

Looking forward to the stars and the moon, Volvo finally released a flagship pure electric SUV—— some time ago. However, in its report, it was impressively written: "It is planned to be produced and sold in the United States in 2023 and localized in China in 2024." In other words, Volvo, whose current main force has already appeared tired, has released new electric products, but it will take two years to meet consumers. Some insiders believe that the pace of Volvo is still so slow in the new energy era, and it is afraid of being abandoned by the market.

At present, if we only look at the sales data of Volvo, there is something gratifying, because in this market where the epidemic situation is repeated and traditional luxury cars and fuel vehicles are eroded by new energy sources as a whole, compared with those friends who are prone to decline by more than ten or twenty points, the cumulative sales of Volvo in the first 11 months of this year has declined by 7.4%.

But Volvo’s real pain lies not in its sales volume, but in its price and brand image: as early as two or three years ago, Mercedes-Benz and Lexus were still increasing their prices, but XC60 was already in a state of "fracture price", with an average discount of 60,000 to 70,000 yuan, and S90 in some areas could even be discounted by 100,000 yuan. On the surface, Volvo’s guide price can still keep up with the first-line luxury, but in fact its price system has almost slipped to the point of competing with joint ventures for the market.

Judging from the financial report, as early as 2019, Volvo’s operating profit in the first half of the year fell by 30%; In the second half of the year, the growth rate of 0.8% was barely maintained through layoffs and other means. In the first half of this year, Volvo’s revenue alone fell by 14.1%; The net income has been completely negative, with a negative growth of SEK 1.171 billion, which dropped by 134.5%. During this period, although Volvo has set foot in PHEV, the actual performance of T8 power is not inferior to that of BBA, but Volvo’s popularity in the hybrid world is not as high as its "Raytheon Hammer" headlights. At this point, Volvo is in urgent need of an innovation.

Fortunately, in the era of electrification, BBA and Lexus, the top four traditional luxury markets, have not come up with strong gestures and products, and consumers no longer give face to their brands and popularity. This can be said to be an excellent opportunity for other so-called "second-line luxury" to break through.

Volvo’s attitude of transforming into electrification is also quite firm: first, it transferred the main shares of Aurobay to Geely, and at the same time announced that it would stop production of pure fuel vehicles in 2025, which announced that it officially withdrew from the research and development of internal combustion engines and focused on electrification. However, the flagship electric technology exhibited by EX90, as well as the latest design, technology and concept, cannot help worrying about Volvo’s future.

First of all, this car was built on the SPA2 platform. Although this is an upgraded platform of SPA, SPA is an oil-electricity sharing platform that has never exploded and has never had a well-known black technology. Even the initiator of Volvo’s big price reduction came from this platform. The upgraded SPA2 is also not surprising: the maximum battery life of the EX90 is only 600 kilometers, and the minimum is only 467 kilometers (competing products can generally be 50-100 kilometers higher); The 8155 chip (which is the mainstream now, and will certainly be compared in two years) used for car engines, and the driving assistance computing power is 250TOPS (now many domestic flagships have a computing power of over 1,000, and most high-end models are in the range of 407Ps, 770N·m, 503Ps and 910N·m), but this is also compared with other traditional luxury brands.

In addition to the book parameters, the face value of EX90 also gives people a feeling of "XC90 pure electric version" (of course, this is indeed shared by oil and electricity platforms). Not only is the appearance lacking freshness, but the simple interior is also difficult to remind people of the word luxury. In addition to these most important information, EX90 is left with some "flowers": for example, its seat is made of environmentally friendly materials made of PET plastic bottles and resin; For example, the car will be equipped with sensors to detect whether children or pets are left behind; It can even charge in reverse, and use its cruising range of up to 600 kilometers to "feed back" the power grid or other vehicles.

As for the product strength of EX90, to be honest, even if it goes on the market at the end of 2022 and sets a price similar to that of XC90 (starting at 500,000), compared with its competitors, it is in a state where there are basically no advantages but many shortcomings. Compared with the new cars produced in recent years, the disadvantage of EX90 is even greater.

To give a few simple examples, the 11.4 million version of Aouita can have a battery life of 680 kilometers, and the entry version has a horsepower of 578Ps; Tucki G9 not only reached 700+, but also gave 508TOPS computing power; And those extended-range players who have broken thousands of battery life are even more annoying. In addition, technologies such as in-car life detection and reverse charging have already been seen in the domestic camp. The strength of EX90, which is average in book and not new in technology, is dangerous even in the 400,000-level market. But EX90 not only has a high probability that the price will be higher than XC90, but also will not be made in China until two years later … Such a performance certainly makes people uninterested.

More importantly, as a flagship, EX90 not only has low expectations, but also makes people’s thoughts on Volvo’s new products drop to freezing point. Is the future Volvo electric car the appearance of this current model after changing from oil to electricity, with a simple vertical screen interior? Compared with the extreme krypton that has blossomed in the high-end market, is Volvo’s future performance and battery life just like this? For the increasingly important intelligent travel, is Volvo such a mentality of running behind others? If so, in the new energy era, let alone Volvo’s luxury status, it will lack characteristics and competitiveness even if it is downgraded to an ordinary brand.

It must be said that Volvo, which is slow in electrification and weak in strength, not only faces being abandoned by the market, but also seems to be at arm’s length with Geely Group. Two years ago, the two companies announced that they would really merge into a group company, but the result after that was not only that the merger failed, but also that their cooperation in the power field came to an end. During this period, not only did Krypton successfully rush into the mid-to-high-end electric vehicle market of 300,000-400,000 grades, but also the geometric new energy, which is the main entry-level market, became the enemy of Ai ‘an. Geely even used the vast structure of SEA to help smart jump from the 100,000-grade fuel market to the 200,000-grade pure electric vehicle market, and the monthly sales volume of 1,000+was also higher than before.

On the other hand, Volvo is determined to realize electrification as soon as possible, but its real strength is still in the stage of plug-in+oil-for-electricity exchange. No matter whether SPA2 compares with the vast architecture of SEA or EX90 competes with Krypton 001, Geely can’t pretend to be a "teacher" when it comes to electrification, but it needs to ask this "senior" some difficult problems about the China market. The reason why the merger of the two companies broke down is probably because Volvo, whose car business was only $1.8 billion at the beginning, has an IPO valuation of nearly $30 billion after ten years of growth, which makes it have the idea of going solo, and perhaps makes it offer a price that even Geely, a "diamond VIP" in the acquisition industry, can’t bear in the merger negotiation.

In fact, Volvo needs Geely more now than it did 12 years ago. Not only because of the huge capital investment required by electrification technology, but also because of Geely’s achievements and strength in this field. For example, in the embarrassing period when Volvo’s sales and profits are both declining, Geely’s vast SEA architecture can help it tide over the difficulties.

However, these two brands in the same group began to "play their own games" in the field of electrification, which needs to concentrate on doing big things: they are extremely separated and independent; Volvo has never been able to use the vast structure of SEA. After 12 years, the couple finally began to sleep in separate rooms. Judging from the situation, Volvo’s soaring valuation is only temporary, and Geely, which has already taken off geometrically, has grasped the future. If we really want to part ways, Volvo may be the one abandoned by superior resources.

Summary:Among many luxury brands, Volvo never shows its edge, and rarely shows its ambition to surpass anyone. From the cost performance of products to the main concepts of safety and environmental protection, it even has many unique places. But after these years, Volvo’s main ideas have not been further recognized by domestic consumers. The slow pace of updating has led to a brand that cannot catch up with the high-end market at the price level and must be discounted in the main market. Faced with this situation, Volvo’s determination to cross the rubicon and "fully and quickly" electrify is worthy of recognition, but its achievements are obviously difficult to reverse the current decline. What’s more, the localization time of EX90 has been set in 2024, and it and Geely have begun to "drift away" in technology … So, Volvo may once again usher in a cold winter.
