Time flies, and 2022 is drawing to a close. In many unforgettable China voices, China moments and China stories, people feel the pulse of development.

　　In this year, big countries focused on innovation and development and bravely climbed the peak. Shenzhou XV was successfully launched, and the Struggler dived 10,000 meters deep. The C919 large passenger plane numbered B-919A set sail from Shanghai Pudong International Airport to Shanghai Hongqiao Airport, marking the official delivery of the world’s first C919 large passenger plane … …

　　This year, China’s economic giant broke the waves on the high-quality development channel.

　　Accumulate thickness into potential and take advantage of it.

　　Facing the stormy international environment and arduous domestic tasks of reform, development and stability, the CPC Central Committee with the Supreme Leader as the core United and led the whole party and people of all ethnic groups to overcome difficulties, intensified macro-control, steadily improved the quality of development, made fruitful achievements in scientific and technological innovation, comprehensively deepened reform and opening up, basically stabilized employment prices, effectively guaranteed food security, energy security and people’s lives, and maintained overall economic and social stability.

　　The economy withstood the pressure and continued to recover.

　　Since the beginning of this year, China’s economy has been affected by many unexpected factors, including global epidemic, high temperature and drought, etc. Under the action of a series of stable economic policies, the economy has continued to recover despite the pressure. The data shows that, according to preliminary accounting, the GDP in the first three quarters was 870.269 billion yuan, which increased by 3.0% year-on-year at constant prices, 0.5 percentage point faster than that in the first half of the year.

　　Consumption is the ultimate demand and has a lasting driving force for the economy. With the support of the policy of stabilizing growth and promoting consumption, China’s consumer demand has generally continued to recover, and its basic role in economic development has been gradually consolidated.

　　In the first three quarters, the contribution rate of final consumption expenditure to economic growth was 41.3%, driving GDP growth by 1.2 percentage points. From January to October, the online retail sales of physical goods increased by 7.2% year-on-year, 1.1 percentage points faster than that from January to September, and its contribution to market sales steadily increased.

　　From the perspective of investment, since the beginning of this year, all parties have actively promoted the implementation of the stable investment policy, and the effect has gradually emerged. In the first 10 months, investment in fixed assets increased by 5.8% year-on-year, investment in manufacturing industry increased rapidly, investment in infrastructure continued to rise, high-tech manufacturing industry grew better, and investment in people’s livelihood such as health care continued to increase.

　　From the perspective of foreign trade, China’s series of policies and measures to stabilize foreign trade and foreign investment have increased their effectiveness, and foreign trade has shown strong development resilience, making positive contributions to stabilizing the macro-economic market. In the first three quarters, the net export of goods and services contributed 32.0% to economic growth, driving GDP growth by 1.0 percentage points.

　　Meng Wei, deputy director and spokesperson of the Policy Research Office of the National Development and Reform Commission, said that China’s economy has withstood the impact of multiple unexpected factors at home and abroad, and has continued to maintain a recovery trend, and the foundation for stability has been continuously consolidated.

　　Accelerate the construction of a new development pattern

　　In November this year, at the Fifth China International Import Expo, the "warm camel" wearing traditional Peruvian national costumes attracted many visitors to punch in.

　　Ma Yuxia, one of the founders of "Warm Camel", introduced that in 2018, the Peruvian alpaca doll brand "Warm Camel" appeared in the first China International Import Expo(CIIE), which was quickly welcomed by consumers in China. Today, "Warm Camel" has established offline sales channels in Beijing, Shanghai and other cities, and sold online on e-commerce platforms, and the number of orders has increased significantly.

　　Against the background of insufficient momentum of world economic recovery, the 5th China International Import Expo(CIIE) still achieved fruitful results: the annual intentional turnover was 73.52 billion US dollars. The grand event was held as scheduled and was widely welcomed, which became a vivid portrayal of China’s accelerated construction of a new development pattern.

　　Through the window of China International Import Expo(CIIE), exhibitors fully feel the determination of China to share market opportunities with the world, and the new opportunities provided by the high-quality development of China’s economy to the world — —

　　China has a population of more than 1.4 billion and a middle-income group of more than 400 million. The consumption structure of residents is in the stage of continuous upgrading, and the per capita GDP has exceeded 12,000 US dollars. The market scale is large and the investment space is wide. China adheres to a high level of opening to the outside world, and speeds up the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other, which will increase confidence and contribute to boosting the world economy.

　　BMW Group Shenyang Lida Factory was put into production, Novo Nordisk increased its capital and expanded its production for the eighth time in Tianjin, and Panasonic Group transferred more business segments such as cold chain equipment production and sales to China … … This year, many foreign companies cast a vote of confidence for China’s economy with practical actions.

　　"At present, the uncertainty of world economic recovery is rising, and China firmly promotes high-level opening to the outside world, which shows that it has a little strength, market potential and policy synergy, which plays an important role in boosting market confidence." Gu Xueming, dean of the International Trade and Economic Cooperation Research Institute of the Ministry of Commerce, said.

　　Long-term positive fundamentals have not changed.

　　Report to the 20th CPC National Congress of the Party pointed out that high-quality development is the primary task of building a socialist modern country in an all-round way. Development is the top priority of the party in governing and rejuvenating the country.

　　"From the next stage, although the international environment is complex and severe, and the domestic economic recovery faces many challenges, the fundamentals of China’s long-term economic improvement have not changed, and the basic characteristics of solid material foundation, vast market space, rich human resources and great development potential have not changed." Fu Linghui, spokesman of the National Bureau of Statistics, said.

　　Fu Linghui introduced that China’s economy has strong resilience, the total economic output ranks second in the world, the industrial system is complete, the supporting capacity is strong, and the advantages of super-large market scale are obvious, and it is fully capable of resisting various risk challenges. Domestic demand is expected to increase, and key industries are expected to continue to play a role. The leading role of innovation continues to emerge, and the effect of stabilizing economic policies continues to emerge. Generally speaking, external shocks are staged and will not change the general trend of China’s sustained economic development. Under the action of various policies and measures, the national economy will continue to recover.

　　2023 is the first year to fully implement the spirit of the 20th National Congress of the Communist Party of China, and it is crucial to do a good job in economic work.

　　Politburo meeting of the Chinese Communist Party, who was held recently, emphasized that we should do a good job in stabilizing growth, employment and prices, effectively prevent and resolve major risks, promote the overall improvement of economic operation, achieve effective improvement in quality and reasonable growth in quantity, and make a good start for building a socialist modern country in an all-round way.

　　Dong Yu, executive vice president of Tsinghua University China Development Planning and Research Institute, said that the current task of stabilizing growth is very important. Implementing the spirit of this meeting and better coordinating epidemic prevention and control and economic and social development will help to further release economic and social vitality; Better overall planning of development and security, effective prevention and resolution of major risks will help to create better conditions for high-quality development, and realize the effective improvement of China’s economic quality and reasonable growth in quantity.

　　With the victory of the 20th National Congress of the Communist Party of China, the new journey of building a socialist modern country in an all-round way has taken solid steps, the new development concept has been deeply rooted in people’s hearts, the new development pattern has been accelerated, and the high-quality development hoof has made steady progress. In the future, China’s economic development prospects will be brighter.

　　(Beijing, December 13 th, by reporter Liu Kun)

　　Helicobacter pylori is a common bacterium, which is mainly parasitic in human stomach and is considered to be one of the main causes of gastritis, gastric ulcer and duodenal ulcer. It is closely related to gastric cancer, gastric mucosa-associated lymphoid tissue lymphoma and other diseases.70% of gastric cancer is related to Helicobacter pylori., listed by the World Health Organization asClass 1 biological carcinogen.

　　If one person is infected, the whole family should be treated.

　　In June 2023, the White Paper "Prevention and Control of Helicobacter pylori Infection in China" issued by the Institute of Infectious Diseases Prevention and Control of China CDC pointed out that the infection rate of Helicobacter pylori among Chinese residents was nearly 50%. Many people in the family have detected Helicobacter pylori, and other family members are also infected.

　　In 2023, an epidemiological survey of Helicobacter pylori infection in 29 provinces showed that the overall family infection rate in China was 71.2%, which was significantly higher than the individual infection rate of 40.6%.

　　This is because Helicobacter pylori mainly exists in saliva, dental plaque, stomach and feces, and there are three main transmission routes:Word-of-mouth transmission, dung-mouth transmission, and common appliance transmission..

　　When a person is found to be positive for Helicobacter pylori, his family may be the first to be affected.

　　Helicobacter pylori can be detected in saliva, feces and vomit of infected people. Used tableware, dental equipment, toilets, etc., as well as contaminated food and water, may become the source of infection.

　　Helicobacter pylori is associated with many diseases.

　　one

　　Infection with helicobacter pylori

　　The risk of intestinal cancer is greatly increased.

　　Studies have confirmed that Helicobacter pylori, which can only survive in the stomach, also has a strong causal relationship with the occurrence of colorectal cancer.

　　2

　　May increase the risk of throat cancer

　　A meta-analysis of 11 studies showed that the infection rate of Helicobacter pylori in patients with throat cancer increased significantly. This is related to the toxins produced by Helicobacter pylori and toxic enzymes.

　　three

　　It not only causes cancer, but also harms the brain.

　　Recently, a study showed that Helicobacter pylori, which causes cancer, can also harm the brain. Compared with people who are not infected with Helicobacter pylori, people infected with Helicobacter pylori have an increased risk of Alzheimer’s disease by 11%, with the highest risk of infection from 7.3 to 10.8 years, and the highest risk of Alzheimer’s disease by 24%.

　　Do 5 points to prevent Helicobacter pylori infection

　　Helicobacter pylori infection is closely related to our daily living habits.Helicobacter pylori is mainly transmitted by mouth, so prevention should achieve these good habits.：

　　one

　　Choose a separate meal system at dinner.

　　Or use male chopsticks to avoid cross infection.

　　Oral transmission is the main route of Helicobacter pylori transmission from person to person.

　　2

　　Disinfect tableware regularly.

　　After washing the tableware at home, put it in the disinfection cabinet, boil it for disinfection or steam disinfection.

　　three

　　Don’t feed your child mouth to mouth.

　　By chewing food, putting a pacifier or spoon in your mouth to test the temperature, parents will spread the pathogenic bacteria in your mouth to your children.

　　four

　　Be sure to wash your hands before and after meals

　　Fecal transmission is also an important way of Helicobacter pylori transmission.

　　five

　　Avoid drinking raw water and eating raw food.

　　The weather is getting hotter, and some people often eat cold food or drink raw water. If food contains microorganisms and is not fully sterilized, it may also lead to Helicobacter pylori infection.

　　All four types of people should check for Helicobacter pylori.

　　People with risk factors include:

　　Peptic ulcer (whether active or not and whether there is a history of complications);

　　Gastric mucosa-associated lymphoid tissue lymphoma;

　　Patients with early gastric cancer underwent endoscopic submucosal dissection or subtotal gastrectomy;

　　Have a family history of stomach trouble;

　　Plan to take long-term non-steroidal anti-inflammatory drugs (including low-dose aspirin);

　　Helicobacter pylori gastritis;

　　Gastric hyperplastic polyp;

　　Helicobacter pylori-related dyspepsia;

　　Long-term use of proton pump inhibitors;

　　Primary immune thrombocytopenia;

　　Unexplained iron deficiency anemia;

　　Helicobacter pylori infection was confirmed (there was no countervailing factor for eradication treatment).

　　The detection methods of Helicobacter pylori includeNon-invasive and invasiveTwo kinds.

　　It is necessary to stop using acid inhibitors for at least 2 weeks and bismuth and antibiotics for at least 4 weeks before detection, otherwise the false negative rate will increase, that is to say, even if there is Helicobacter pylori infection, it may not be detected.

　　Non-invasive means collecting gas, stool and blood samples, usually including urea breath test, monoclonal stool antigen test and serological test.

　　Invasive methods are based on mucosal biopsy under gastroscope, usually including rapid urease test, pathological staining of gastric mucosa, Helicobacter pylori culture and polymerase chain reaction.

　　Find out whether Helicobacter pylori should be eradicated?

　　After being infected with Helicobacter pylori, patients may have symptoms such as heartburn, halitosis, burping, stomachache, nausea and vomiting, but only a small number of people will have symptoms.

　　The eradication of helicobacter pylori should be adhered to"Individualized assessment and treatment" principle. After the doctor makes a clear diagnosis and the patient has corresponding disease manifestations, it needs to be given appropriate treatment; If the patient is asymptomatic, he has reservations about eradication treatment.

　　If the infected person has peptic ulcer, Helicobacter pylori gastritis, gastric hyperplastic polyp, Helicobacter pylori-related dyspepsia, unexplained iron deficiency anemia, immune thrombocytopenia or family history of gastric cancer, it needs radical treatment.

On August 15 th, when it comes to this year’s superstar in the automobile industry, who is capable of dominating the crowd and dominating the crowd? It belongs to BYD Qin L. Thanks to the blessing of the fifth-generation DM technology, it can easily span the magnificent mileage of 2,100 km in the state of full oil and electricity. Even if the power is insufficient, the fuel consumption is only 2.9L/100km, which is a model of energy saving. But outside the spotlight, there is a dusty pearl-Roewe D7 DMH. Although its light is temporarily concealed, it is a powerful faction that cannot be underestimated. Today, let’s unveil its mystery and explore whether it can really become the best choice among the "100,000-class hybrid B-class cars". Experience it, and maybe you will find that the surprise is far more violent than you thought.

BYD Qin L and Roewe D7 DMH, each holding one end in the design language, show different aesthetic concepts. Qin L, like a flying dragon, has an upgraded "dragon face" design with complicated and agile lines. Every detail exudes a strong charm of traditional cars, especially the domineering air intake grille, which shows the pedigree of its fuel car. Roewe D7 DMH, on the other hand, is a minimalist in the new energy era. Its front face design is clean and neat, and its lines are concise and full of tension, which perfectly interprets the design philosophy of "less is more", making people feel the breath of future technology at a glance.

In appearance, they seem to be two parallel rivers. Qin L flows with the waves of tradition and strength, while Roewe D7 DMH quietly tells the story of purity and refinement. They interpret different understandings of beauty in their own unique ways.

In the arena of body design, BYD Qin L and Roewe D7 DMH each performed a double performance of speed and elegance. Qin L outlines the perfect combination of strength and beauty with a resolute waistline, while D7 DMH interprets a low-key luxury and calmness with a smooth and delicate body curve. It is worth mentioning that the D7 DMH is slightly superior in size, its length is 6 cm longer than that of Qin L, and its wheelbase is 2 cm wider, which not only gives it a more magnificent appearance, but also provides more spacious and comfortable interior space for drivers and passengers, making every trip an elegant journey.

Shuttle to the rear chapter of the car body, BYD Qin L seems to be the younger brother of the "Han" family, inheriting that extraordinary style, exquisite and elegant. Roewe D7 DMH, on the other hand, shows its class, and at the same time, it skillfully incorporates the smart design of the duckling tail, adding a touch of vitality to the whole. At the tail light of Qin L, the popular penetrating design and the strong "China element" complement each other, showing a unique visual charm. Roewe D7 DMH, on the other hand, chose the classic split taillights, which are traditional but have their own characteristics in visual presentation.

In every day’s rush, there is such a moment that we quietly cherish. Are you familiar with the "ten minutes of silence after the car stops" At that moment, we shed all the roles entrusted by society-colleagues, husbands, sons and fathers, and returned to our purest selves. For men, this short silence is a rare "private moment" and a "third living space" of their own. Here, every inch of space and atmosphere is telling the pursuit and yearning for quality life.

This is not only the end of a journey, but also the habitat of the soul. In this small world, we can temporarily pull away and find inner peace. Therefore, a private space full of style is self-evident for every man. It not only bears the daily fatigue, but also witnesses every real moment and becomes an indispensable spiritual harbor for us.

Roewe D7 DMH, in the name of "Yunsu Intelligent Cockpit", invites you to enter a journey in the cloud. Here, the comfort is beyond imagination, as if you are in the clouds, light and quiet; Intelligent technology, at your fingertips, makes every trip a pleasure.

Interior design, stretching the atmosphere, delicate touch, suede material package, so that visual and tactile double enjoyment. Qin L, though unique, has a large area of piano paint decorative board, which is beautiful but easy to reflect light and stain, and the details are a little regrettable.

Roewe D7 DMH’s seat is ingenious, made of 9-layer composite materials, with excellent sitting feeling. The largest backrest and cushion at the same level are added with 2 cm thick soft foam, which perfectly fits the human body curve. Long-distance driving can also keep your back comfortable and bid farewell to fatigue. In contrast, Qin L’s seat looks mediocre and lacks bright spots.

Roewe D7 DMH is not only a car, but also a smart residence above the cloud, inviting you to experience an unprecedented new realm of driving.

On the intelligent track, BYD’s DiLink system may not be the most dazzling star, and its chip configuration is not 8155 or 8295, but its stable performance is a bright spot, and there is almost no embarrassment of jamming, black screen or downtime. Roewe D7 DMH, on the other hand, goes a step further in intelligent technology, equipped with an upgraded zebra intelligent driving system, which is not only superior in human-computer interaction, but also richer in functionality. What’s more worth mentioning is that the car adopts the 8-core 64-bit processor of the car specification, which ensures that every operation is silky smooth and makes the driving experience more pleasant.

When it comes to the hybrid system of new energy vehicles, the technical core is undoubtedly the key. The fifth-generation DM technology equipped by Qin L and Roewe DMH system are like twin brothers, sharing the exquisite design of 1.5L engine and single-gear gearbox. In terms of hardcore indicators, whether it is the comprehensive cruising range with full oil and full electricity or the fuel consumption of 100 kilometers in the state of power loss, the performance of these two models can be called equal. However, Qin L’s 65-liter fuel tank, compared with Roewe D7 DMH’s 55-liter fuel tank, undoubtedly provides more abundant energy reserves for long-distance travel, and this difference in detail is enough to make drivers feel more comfortable driving experience.

When it comes to the performance comparison between Qin L and Roewe D7 DMH, Qin L’s 1.5L engine leads with a thermal efficiency as high as 46.06%, while Roewe D7 DMH follows closely with a thermal efficiency of 43%. Although the thermal efficiency is slightly inferior, Roewe D7 DMH shows stronger performance in terms of power and torque, which ensures that the vehicle is full of power and is not prone to power attenuation when driving at high speed or accelerating rapidly.

Another highlight of Roewe D7 DMH is its innovative P1 motor design, which abandons the traditional balanced shaft layout and adopts the structure coaxial with the engine. This design not only significantly improves the output efficiency, but also brings a smoother and quieter driving experience. What’s more worth mentioning is that the cooling efficiency of Roewe D7 DMH has increased by 30%. This improvement not only effectively improves the durability and stability of parts, but also further optimizes the overall performance of the vehicle, making every driving more secure and comfortable.

Roewe D7 DMH, a new realm of mixing. Its hybrid gearbox is compact and light, with soaring output power, jumping integration and outstanding mechanical transmission efficiency of 98.5%. In contrast, the efficiency of EHS hybrid system with the fifth generation DM technology is slightly lower, only 92%. DMH super hybrid system, equipped with powertrain brain PICU, the operation speed soared by 50%, and the dynamic response was as fast as lightning. The electronic and electrical architecture of the fifth generation DM technology, the power domain control is upgraded to seven in one, and the strategy focuses on fuel economy. Roewe D7 DMH is designed with different original intentions. BYD pursues fuel economy like Toyota in the old days, while Roewe pursues both power and economy. The design is more elegant, the interior is more luxurious, the space is more spacious, the hybrid technology is more advanced and the performance is more balanced. 100,000-class hybrid car, Roewe D7 DMH, your first choice.

　　　　[XCAR Technology Original]

　　　　I believe that card friends are no strangers to the "wind resistance coefficient". When the vehicle is driving at a low speed, the resistance mainly comes from the friction between the tire and the ground. When it reaches a certain speed, for example, when the speed exceeds 110km/h, about 70% of the resistance of the vehicle comes from the impact of airflow, which is what we often call air resistance. The magnitude of resistance is generally measured by wind resistance coefficient. The drag coefficient of our common cars is mainly between 0.28 and 0.4, so how to design the body shape and chassis to achieve the most reasonable drag coefficient has become one of the biggest problems faced by many car companies.

　　　　For family cars, low drag coefficient is particularly important, because it directly affects the fuel consumption and noise level of vehicles at high speed. Therefore, sometimes even the performance and appearance of some vehicles are sacrificed in pursuit of lower drag coefficient.

　　　　So how is the drag coefficient measured? After all, we can’t consider the data published by car companies, especially the "illusory" data like drag coefficient. To this end, we came to the Shanghai Ground Vehicle Wind Tunnel Center in Jiading Campus of Tongji University in Shanghai to reveal the whole process of this experiment. The brand-new 7-seat MPV Auchan of Changan is our test vehicle. Judging from the officially announced drag coefficient of 0.334, it is definitely at the top level in the same class, even far exceeding some joint venture brands.

　　　　Shanghai Ground Vehicle Wind Tunnel Center can be said to be the most advanced vehicle wind tunnel center in China, which cost 500 million yuan to build and has been tested by hundreds of enterprises. I have to ridicule here that it is absolutely extravagant to "blow the wind" in the experimental room. According to the staff, their charging standard is in minutes, and it takes 400 yuan RMB to blow for one minute. Under normal circumstances, it takes nearly 8 hours for a car to complete all the test processes, and the total cost is about 250,000 to 300,000 yuan. Of course, this has not calculated other additional costs such as transportation and labor. Normally, a new car needs to do three wind tunnel tests, and through the process of improvement and retest, it can reach the most perfect state.

　　　　We should know that not all car companies will choose wind tunnel test when developing new models, and some of them will use computer simulation to simulate the test process. Although the cost is relatively low, the accuracy of the measured data remains to be discussed.

　　　　Changan Automobile is not "spending money like water". They reasonably combine the two testing methods. In the early development, they used computer simulation technology to improve the design of the body and chassis as much as possible to achieve lower drag coefficient and quiet cabin space. In the final stage, the real wind tunnel test was used to improve the shortcomings of the vehicle and improve it. It can also be seen that Changan Automobile has invested heavily in this brand-new home MPV and has high expectations.

　　　　Through this reasonable development process, the drag coefficient of Auchan finally reached 0.334. Because of the demand of interior space, this MPV model can not achieve the streamlined structure like a car, so it is necessary to make up for its disadvantages as much as possible through scientific treatment of some details. Because the positioning of MPV models is completely family-oriented, who can achieve lower fuel consumption and noise while ensuring space can be more popular.

Everyone must think about their actual needs when buying a car, so as to have a more targeted choice. There are many bright spots. Today, let’s talk about how it performs in terms of power. Let’s take you to appreciate its style.

First look at the appearance of Buick GL8 plug-in hybrid. The front face of Buick GL8 plug-in hybrid looks elegant and sporty. The headlights are deep and the shape is quite avant-garde. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Come to the side of the car, the car body size is 5219MM*1878MM*1807MM, the car uses tough lines, the side feels very soft, with large-sized thick-walled tires, it looks full of movement. In the design of the rear end, the rear end looks simple, and the taillights look simple and generous, and the sense of neatness is vivid.

Coming into the car, the front face of Buick GL8 plug-in hybrid looks very fashionable and reflects the sense of design. The car’s steering wheel design is very elegant, equipped with the functions of manual steering wheel up and down+front and rear adjustment, and the feel experience is good. Take a look at the central control, with a 30-inch central control screen, which makes the interior design quite layered and looks very avant-garde personality. The dashboard and seats give people a good feeling, too. Let’s take a look. The dashboard design is remarkable and full of technology. The car uses leather seats, equipped with auxiliary seat electric adjustment, seat with memory electric adjustment, seat proportion down and other functions, and the overall comfort is acceptable.

The car is equipped with car networking, driving mode selection, remote control key, Bluetooth key, rear wiper, interior atmosphere light and other configurations, and the configuration performance is quite good, bringing drivers and passengers a comfortable car experience.

Such a car with the right price is enough to meet the daily practical needs, and it doesn’t take much thought to maintain it at ordinary times, and the cost performance is good. If you like this car, don’t hurry to learn more about it!

The leadership behind Dong Mingzhu is even more remarkable.Her strength is really unmatched.
at presentShe chose to expand her territory in the automobile field, and there must be her careful consideration behind it. The establishment of Gree Automobile has a registered capital of 20 million yuan, which is not a small number. You know, the competition in the automobile industry today is extremely fierce. Many enterprises have been rolling on this road for many years, but they have failed to find their own position. But what kind of determination does Dong Mingzhu convey behind this?

Gree’s entry point in the automobile field is not random. In fact, as early as 2016, she entered the new energy industry through the acquisition of Zhuhai Yinlong, which can be said to be a bold investment. Think about it, at that time, she joined forces with Wang Jianlin, Liu Qiangdong and other business tycoons and invested 3 billion yuan.Every step of the way is very cautious.,Not everyone dares to do this.Now, with the establishment of Gree Automobile,It seems that I want to make good use of my previous investment., further develop.

Come to think of it carefully, Dong Mingzhu and her team have really experienced a lot of ups and downs on this road of "building a car".The acquisition of Yinlong New Energy made her suffer a lot.Although it later increased its capital by 23.4 billion yuan, it was unexpectedly hit hard by the founder Wei Yincang absconding with money.it is not too much to sayThis experience is really frightening.It’s a little more overwhelming.Yinlong’s performance is like riding a roller coaster, falling all the way to a loss of 2 billion in 2022. Presumably, Sister Dong must be unhappy to see such data.

Despite these challenges, Dong Mingzhu still hasn’t given up. What she wants to build is not only a car, but also an idea! Think about it, she crossed the car circle from the home appliance circle, which is not only the investment of capital, but also the accumulation of technology and the reshaping of the brand. Gree intends to be more than just satisfied with manufacturing auto parts this time.I want to find my place in the whole industrial chain.,This idea is not simple.I really have to think about it.

Faced with such a challenge

Lei Jun is not idle either.
His "millet car" has already fired and started running.Nowadays, the two "business giants" are competing in this almost smoke-free automobile industry, which really makes people look forward to it. As a relatively young company, Xiaomi has to admit its appeal because of its strong market appeal and brand influence. Lei Jun has also made a lot of efforts in building cars in an attempt to create a more intelligent travel experience. Obviously, the chess game is becoming more and more complicated.

Why did this "war" attract so much attention? Of course, it was because of the reputation of two business leaders, but also because of the team and resources behind them. As a strong woman in the workplace, Dong Mingzhu’s mind and wisdom undoubtedly injected a shot in the arm for Gree.And Xiaomi in Lei Jun’s hands should not be underestimated., the confrontation between these two brands,Let’s not only look forward to their productsAnd look forward to their innovative ideas.

Having said that, you may think that the road of building a car is not a simple capital investment. If you want to fight hard on this increasingly congested road, the core competitiveness of the product is fundamental, whether it is technology, design or after-sales service.Nothing can be less,And this is exactly where many new energy car companies are having a headache.According to statistics, there have been countless new energy vehicles that have suddenly risen.In the end, due to the lack of core technology or financial problems., which led to the death of many car companies.

Besides Gree.

In addition to the basic equipment, Dong Mingzhu has also taken a group of excellent teams to integrate the high-level fields such as industrial internet and intelligent robot research and development. The potential behind this also makes people look forward to Gree’s future performance.
If Gree can rely on its own supply chain advantages,The combination of air conditioning technology and automobile manufacturing may not lead to a "car-making revolution"

Let’s talk about the attitude of consumers.In today’s eraConsumers’ demand for cars is no longer as simple as "being able to run and sit".More is the pursuit of intelligence, environmental friendliness and excellent cost performance.If Gree can dig out enough value in these aspects, the support of consumers will naturally become an additional driving force, and well-known people in the industry have also praised it.Think that as long as you have determination and abilityGree’s non-stop in the new energy vehicle market will not disappear in the historical trend.

Now,A new round of competition rekindled in the automobile market.Especially in the wave of intelligence and new energy,The collision between traditional giants and emerging forces is expected.Dong Mingzhu brought Gree’s strong strength and innovative spirit into the automobile circle.Such an attemptIt may bring new enlightenment to the future automobile industry.

For the opposition between Dong Mingzhu and Lei Jun,Who can laugh at the result may not be clear overnight.This business war is full of suspense,Perhaps one dayWe will see the competition between the two giants in product quality and technology, which will eventually lead the transformation and development of the whole industry.

In any case, Gree’s dream of building a car is not destined to be an easy journey. The challenges and sparks in the future deserve our attention. You can also leave your views on Dong Mingzhu’s dream of building a car in the comments section. Maybe you can become the next wise man who cares about the next seven roads!
