What led to the end of the Soviet Union? There are many reasons for this, which cannot be simply attributed to a certain reason or a person’s mistake.

　　　 First of all, Russia has a 370-year tradition of czar absolutism, and it lacks the practice of capitalist democratic constitutionalism. The tradition of czar’s autocracy permeates every corner of society, which has an impact on the people and communist party. This is an objective reason. Secondly, the problem of how communist party led the Soviet Union was not solved. During Lenin’s period, there was inner-party democracy, Soviet democracy was not enough, and multi-party cooperative democracy no longer existed after 1920. If inner-party democracy, Soviet democracy and multi-party cooperation democracy can be developed, it should be said that the Soviet Union will not perish. Finally, the personal characteristics of leaders also play a role. If Lenin could live 20 years longer, the Soviet system would certainly not be deformed or declined. Lenin graduated from the Faculty of Law of Petersburg University, lived in capitalist democratic countries in Western Europe for 15 years, and founded socialist democracy in Russia.

　　　 If the Soviet Union implements a democratic and Republican political system, and if the Soviet Union is the highest organ of state power with real power, then it can correct the wrong line of the ruling party. Stalin did not practice the unity of the general leadership positions of the party and government, but pioneered the personal centralization system, the tenure system and the designated succession system, which combined the three powers of the party, government and army, thus turning the Soviet Union into a rubber stamp. Therefore, in the end, the Soviet Union could neither correct Stalin’s "Left" line error, which had been pursued for a long time since 1929, nor correct Gorbachev’s right line error.

　　　 Therefore, the first lesson we should learn from the drastic changes in the Soviet Union is to speed up the reform of the political system with excessive concentration of power and to develop and expand socialist democracy and freedom. With democracy and freedom and the guidance of scientific theory, a correct political line can be formed; With science and democracy and freedom, even if the political line is wrong, it can be corrected in time.

　　From the current market point of view, at least one or two mobile phone brands in China will build their own self-developed systems and chips in the future.

　　Because the ultimate goal of terminal products is to build their own systems, chips and ecology. As long as these are done, they will get rid of more constraints.

　　However, Huawei’s advantages in the field of multi-device interaction are obvious to all, and many systems of major manufacturers have begun to integrate this capability.

　　It’s just that whether we can learn from Huawei to build an independent system in the future depends on the determination of each family. After all, ecology is difficult and it takes time to accumulate.

　　However, in terms of system ecology, Huawei’s mobile phone has started to take the lead, especially after the release of Huawei HarmonyOS OS4.0, which has brought many surprises.

　　For example, the Ark engine is brought, and even the old model will be greatly improved in fluency after being updated to the new version after being added to the mobile phone.

　　The key point is that the increase in popularity is also very exaggerated. Even the glory old models have been upgraded and pushed, which shows how sincere they are.

　　The key point is that with the passage of time, I found that Huawei HarmonyOS OS5.0 has been confirmed again, and it should be completely separated from Android, so I feel that there will be no constraints.

　　It is reported that HarmonyOS industrial chain sources revealed that HarmonyOS version 5.0 will no longer be compatible with Android, HarmonyOS is HarmonyOS, and Android is Android.

　　Moreover, according to Huawei’s release habit from generation to generation, HarmonyOS 5.0 is expected to be officially released in the second half of next year, which means that it is not far away to say goodbye to Android.

　　The key point is that according to previous reports, Huawei insiders said that in the future, HarmonyOS will form a’ hard fork’ with Android, and Android, iOS and HarmonyOS will be three completely independent operating systems.

　　This also means that it is certain that HarmonyOS OS will leave Android in the future, and there is even great hope to spoil the whole mobile phone market.

　　In addition, HarmonyOS OS system has also made crazy efforts for the pure native ecological environment. For example, the first batch of Internet manufacturers announced their participation in the development of native applications in HarmonyOS.

　　Moreover, some developers said that Internet companies are developing HarmonyOS-specific apps one after another, which is necessary because HarmonyOS and Android systems are no longer compatible in the future.

　　Moreover, Huawei’s current market volume is still very large. I believe that every company will not give up and may even become the mainstream of the next domestic market.

　　However, Huawei recently said that there is no plan to use HarmonyOS for overseas mobile phones at present, and overseas consumers can continue to use Android applications with confidence through Huawei mobile phones equipped with EMUI version.

　　Simply put, Huawei’s HarmonyOS OS system is still in the process of development. If Harmony OS can’t provide a mature application ecosystem, it will be difficult to meet users’ daily use.

　　Therefore, it is normal to continue to use EMUI overseas, while it is an inevitable choice to use Android system as the bottom layer and improve it based on OpenHarmony in China.

　　However, there are still many problems that Huawei mobile phones need to face next, such as weak willingness to develop, lack of developers, unfamiliar development environment and many other problems.

　　So, if you really want to make Huawei’s HarmonyOS OS system rise, you still need real efforts. Otherwise, the market pressure will be really great.

　　Of course, once the HarmonyOS OS5.0 version is released and brings a series of powerful features, the future development pressure will be very small.

　　Because today’s HarmonyOS OS4.0 version has brought excellent experience, and its functions and features are far ahead of those of friendly models.

　　In addition, the strength of Huawei’s mobile phone is not weak, especially the attack of Kirin 9000s processor, which brings a very good experience.

　　Thus, as long as the development speed of Huawei’s HarmonyOS OS system is surprising enough, it will greatly improve the overall development of Huawei.

　　Finally, I want to say that the self-developed system itself is not difficult, but it is difficult to build a complete and positive cycle of application ecology.

　　Then the question is coming. Do you think HarmonyOS OS system is divided into three parts, or is it a middle way collapse? Welcome to reply to the discussion.

Changan is a compact car owned by Changan Automobile. Its competing models include Geely, Arrizo GS and Hehe, and it is the key model of Changan Automobile’s compact platform. With its high cost performance, it has gained a share in the compact market. So how about Changan Yidong is worth buying? Let Xiaobian take you to analyze the advantages and disadvantages of Changan Yidong from word of mouth.

First of all, let’s look at its advantages:

1. High fuel economy. Changan Yidong has been praised by many car owners for its fuel consumption performance. When driving or running at high speed, the fuel consumption is generally 6L-7L/100KM, and it will not exceed 8L/100KM in the case of traffic jams in urban areas. This fuel consumption level is almost equal to that of some Japanese cars that are fuel-efficient.

2, the seat is comfortable. In terms of comfort, it can be seen that Chang ‘an Yi Yi has spent a lot of time. No matter the softness of the seat or the angle of the backrest, it is more ergonomic. No matter the front and rear rows, there will be no discomfort during long-distance driving. It is quite good to achieve this level at this price.

3. Rich configuration. It’s hard to imagine that Changan Yidong has equipped you with many practical configurations such as remote start, cruise control, automatic air conditioning and keyless entry. On the other hand, there is no such configuration for a joint venture car of the same level. I think Changan Yidong has invested several streets in configuration.

Let’s talk about the shortcomings of Chang’ an Yidong:

1. Poor sound insulation. Many car owners spit out Changan Yidong, especially when running at high speed, the wind noise and tire noise are particularly obvious, but I think that among the rival models of the same level, how many sound insulation are excellent? Fortunately, the noise is relatively less after the owner changed the silent tire.

2, low speed frustration. Its seven-speed wet powershift can feel obvious frustration when driving at low speed, and it will be more serious when following the car at low speed in urban congested sections. After all, if a family car has obvious frustration, it will always feel that something is wrong.

3. The chassis has poor texture. Although the comfort of the seat is excellent, its texture is relatively thin, and it is not very good for some vibrations. When passing through the continuous potholes, there is still a sense of bumps in the car, which may be unfriendly to most friends who drive on unpaved roads.

Summary: After reading the advantages of Changan Yidong and combining with its disadvantages, you will find that almost all the disadvantages are covered by the advantages. In the same class, its advantages are often brighter than its disadvantages. If you only have a budget of 100,000 yuan, then Changan Yidong is worth buying.

Why did the tire pressure drop when the car stopped for a few days? How much is normal for a tire to leak in a month?

After the car stopped for a few days, it may be that there is jogging gas, which may be caused by the following situations:

1. Unreasonable driving habits lead to side wear. For example, if you cut the road teeth, it will increase the wear of the tires after many times, and jogging gas will appear after a long time.

2, tire aging, due to long-term use of tires, there will be problems such as aging and cracking, which will also lead to the phenomenon of slow deflation of tires. Jogging gas in this situation is difficult to find, and it can be detected by making the gas sufficient or exceeding the normal pressure properly.

3. The wheel hub is deformed. Under normal circumstances, there will be no jogging gas when the outer edge of the tire is closely connected. However, if the wheel hub is deformed, the tightness between the wheel hub and the tire will be poor, which will further lead to tire leakage.

Under normal circumstances, it is normal for the tire to leak about 0.02bar a month. In the cold state, the front tire pressure of the vehicle is 2.2-2.3 and the rear tire pressure is 2.4-2.5, which is within the normal range, but some of them are 2.4-2.5 and 2.2-2.3, depending on the tire pressure marked on the vehicle. According to the principle of thermal expansion and cold contraction, the tire pressure in summer can be lowered by 0.1-0.2 compared with the normal value, while the tire pressure in winter can be raised by 0.1-0.2 compared with the normal value.

Tire pressure is an important content in our tire maintenance. We should keep the tire pressure within the normal range. Too high and too low tire pressure will affect our driving and even increase the safety hazard. When the tire pressure is too low, it may make the steering wheel sink and run off, and it will also increase the degree of tire wear and shorten its service life, so we should pay more attention to the situation of tires.

　　The situation in Idlib province in northwestern Syria, which is heavily besieged, has turned for the better because of the latest talks between Russian and Turkish leaders.

　　According to a report by CNN)9 on September 18th, after the previous day’s talks in Sochi, Russian and Turkish leaders agreed to set up a non-military buffer zone in Idlib province, Syria, in order to separate the Syrian government forces from the local rebels.

　　According to the agreement, the non-military buffer zone in Idlib province is about 15 to 20 kilometers wide, including tanks, rocket launching systems, mortar launchers and other heavy weapons and "extremist militants" will be evacuated from this area. After the non-military buffer zone came into effect on October 15th, Russian troops supporting the Syrian government and Turkish troops supporting some anti-government forces will organize patrols in the local area.

　　Within a few days, the situation in Idlib changed suddenly, which seemed unexpected, but it was reasonable.

　　Within 10 days, the situation changed suddenly.

　　Idlib province, located in the northwest of Syria, is the last important territory held by the rebels in the country. In the past few weeks, Syria has insisted on "recovering every inch of territory" and joined forces with Russian troops to attack around Idlib. War is on the verge.

　　However, around this "last battle", the international community criticized everywhere.

　　Turkey, many western countries and the United Nations have repeatedly warned that if the Idlib war starts, it will cause a huge humanitarian crisis.

　　According to media statistics, there are still nearly 3 million people living in Idlib province, including 1 million children. The recent escalation of tensions has led to the displacement of more than 30,000 people.

　　At the summit of Russia, Iran and Turkey held on September 7th, the differences between Turkey and Russia were highlighted around Idlib "to fight or not to fight".

　　After the summit, Russia and Syria continued their air strikes in Idlib, while Turkey, under the pressure of public opinion, stepped up its efforts to dispatch troops and arm pro-Turkish rebels in Idlib.

　　But only 10 days later, Russia and Turkey reached an agreement.

　　"Through this agreement, I believe that we will prevent a serious humanitarian crisis in Idlib." Turkish President Erdogan stressed the value of the above agreement to reporters in Sochi, Russia on the 17th.

　　According to the Russian media Tass news agency, the Russian Defense Minister confirmed that no new military operations will be carried out in Idlib province.

　　Russia and Turkey have their own problems.

　　Behind the rapid agreement between Turkey and Russia is their own unspeakable secrets.

　　On the one hand, Turkey, which lacks support, is unable to confront the Russian-Syrian army head-on.

　　Wei Min, a researcher at the Institute of West Asia and North Africa of China Academy of Social Sciences, told The Paper (www.thepaper.cn) during the 6th International Forum on Asia and the Middle East sponsored by the Middle East Institute of Shanghai International Studies University that under the current situation, the United States has no intention to support the rebels in Syria on a large scale, and Turkey, which is deeply mired in the Lira crisis, may not have the energy to deeply participate in the military operations in Idlib.

　　On the European side, "in the context of Brexit, building economic relations with various regions of the world is an important concern for Britain at present, and Britain will have no intention of deeply intervening in Syrian military operations." Eugene Rogan, director of the Middle East Center of Oxford University in the UK, added to The Paper at the 6th Asia and Middle East International Forum that French action in Middle East affairs is also limited.

　　On the other hand, Russia, which seems to be winning, is also worried. Russia, which has twice announced its withdrawal from Syria, has suffered a lot in the Syrian battlefield in the past three years. Later in the day when the agreement was reached, a Russian Il -20 military plane was accidentally hit and crashed by a Syrian S-200 defense system intended to intercept Israeli missiles, killing all 15 people on board.

　　"For Russia, the best solution is that the opposition armed forces in Idlib have surrendered under heavy pressure and then been reorganized into a part of the Syrian government forces." Gong Zheng, assistant researcher of Middle East Institute of China Institute of Contemporary International Relations, told The Paper that the current new Russian-Turkish agreement is not far from Russia’s best plan on the whole, and it is a better way to safeguard Russia’s interests.

　　In addition, according to analysts quoted by The New York Times, by suspending military operations in Idlib, Russia also hopes to take this opportunity to give the Syrian government a more favorable opportunity in the upcoming political consultation process and avoid a more negative impact on the Syrian government due to a war that caused a huge humanitarian disaster.

　　Can setting a non-military buffer zone bring peace?

　　Although Turkey and Russia have not yet determined the specific details of establishing a non-military buffer zone, and Russia still needs to negotiate and coordinate with the Syrian government, the tense situation has eased with the conclusion of the Russian-Turkish agreement.

　　Robert Ashley, director of the US Defense Intelligence Agency, optimistically predicted that the talks between Russian and Turkish leaders on the situation in Idlib province in Syria brought hope for reconciliation.

　　"Russia and Turkey agree that the planned steps and actual implementation of the two countries will provide new impetus to the process of political settlement of the Syrian conflict, and may stimulate the efforts of the Geneva peace talks, thus contributing to the restoration of peace in Syria." Russian President Vladimir Putin believes that the new agreement may eventually end Syria’s long and devastating civil war.

　　However, the mixed dilemma in Idlib seems to be difficult to be solved by the conclusion of the new agreement.

　　At present, there are dozens of anti-government armed factions in Idlib province, including the extremist organization "Conquest Front". However, tens of thousands of extremists and anti-government armed men called moderate opposition by western countries are mixed with each other, which has become the crux of the complicated situation in Idlib.

　　The British Broadcasting Corporation (BBC) reported that although Russia and Turkey have reached a non-military buffer zone agreement, which leaves room for further diplomatic actions, in the long run, it is difficult for the agreement to accurately solve the above practical problems.

　　"The mutual compromise between Russia and Turkey is of positive significance, which shows that Russia, Turkey and Iraq can resolve their differences through negotiations, effectively quell conflicts on the ground battlefield and avoid mass deaths of civilians." Gong Zheng also stressed that the establishment of the non-military buffer zone can only partially ease the conflict. "This does not mean that peace will come quickly."

　　The above-mentioned extremist organization "Conquest Front" will be excluded from the Russian-Turkish ceasefire, and air strikes by all parties around the fight against terrorism are expected to continue.

　　Moreover, Gong Zheng pointed out that the Kurdish armed forces supported by the United States still control the northeast of Syria, while a small opposition force still occupies the Tanf area in the southeast, and the United States itself has more than 2,000 soldiers deployed in the Syrian battlefield. At the same time, Turkey’s "Olive Branch Military Operation" in Syria continues, taking control of several towns in the north. Israel has long carried out air strikes in southwestern Syria to combat pro-Iranian forces in Syria.

　　In this complex background, for the Syrian government, which vowed to "recover every inch of territory", the "military plan" still seems hard to give up.

　　China news agency, Washington, June 6-US President Biden published a signed article in Washington post on June 6, looking forward to his first overseas visit agenda. He said that this trip to Europe is to show the "renewed commitment" of the United States to its allies.

　　According to the schedule released by the White House, Biden will leave for Europe on the 9th Eastern Time, starting his first visit during his term of office. After meeting with British Prime Minister Johnson on the 10th, Biden will attend the G-7 summit in Britain from 11th to 13th, and attend the NATO summit and the US-EU summit in Brussels from 14th to 15th. On the 16th, Biden will travel to Geneva, Switzerland to hold a bilateral meeting with Russian President Vladimir Putin.

　　At the beginning of the article, Biden said that at this moment of global uncertainty, the world is still struggling with the Covid-19 pandemic. "This visit is to show the renewed commitment of the United States to its allies and partners.".

　　Biden highlighted the G-7 summit, the NATO summit and the meeting between US and Russian leaders in his article. He said that "the United States must lead the world in a strong position" whether to end the COVID-19 epidemic worldwide or to cope with the growing climate crisis.

　　Biden pointed out that the leaders of the G-7 countries have not met face to face for two years due to the COVID-19 epidemic. "Ending this virus pandemic, improving public health security in all countries and promoting a strong and inclusive global economic recovery will be our top priority."

　　For the NATO summit, Biden said that he will reaffirm the firm commitment of the United States to NATO’s common defense and ensure that NATO remains strong in the face of every challenge, including threats such as cyber attacks against the key infrastructure of NATO member States.

　　When talking about the meeting between the leaders of the United States and Russia, Biden particularly emphasized that the meeting was "conducted after high-level discussions with friends, partners and allies." He said that the United States and Europe will unite to deal with Russia’s challenges to European security, starting with the Ukrainian issue.

　　Biden said that in his previous call with Putin, his attitude was "clear and direct". The United States does not seek conflict, but wants stable and predictable bilateral relations between the United States and Russia, so as to cooperate with Russia on strategic stability and arms control.

　　Since the Biden administration came to power, the United States and Russia have made progress in extending the validity of the New Strategic Arms Reduction Treaty, but the confrontation on Ukraine, cyber security, human rights, election intervention and other issues has intensified.

　　In April this year, the US government imposed large-scale sanctions on Russia and expelled 10 Russian diplomats on the grounds of malicious activities such as cyber attacks and interference in US elections. Russia then took a reciprocal response and expelled 10 American diplomats in Russia.

　　Biden said in an article on the 6th that he had taken a "meaningful response" to the violation of US sovereignty. "President Putin knows that I will not hesitate to respond to harmful activities in the future." He also said that when meeting with Putin, he will once again emphasize the positions of the United States and Europe on related issues.

　　For Biden’s first foreign visit, the White House said in a statement on the 3rd that the purpose of this visit is to emphasize that the United States is committed to restoring relations with its allies, reviving the transatlantic partnership, and responding to global challenges through close cooperation, so as to better safeguard the interests of the United States.

　　"You need to change this air filter."　

　　-Technicians often remind you to change the air filter.

　　But can you really tell the difference between two kinds of "air filtration"?

　　Both air filter and air conditioner filter filter air. What’s the difference between them? Today, Xiaobian will give you a detailed explanation.

　　First of all, focus! Remember clearly:Air filter is to filter the air entering the engine, while air conditioner filter is to filter the air entering the cab.

　　A protective engine,

　　A protector!

　　Although they have different positions, different functions and different replacement cycles,But they are equally important.

　　Location:　Open the front hood of the vehicle, usually around the engine (different models and different directions). Just open the fixing screw on the air filter box with a screwdriver and you can see the air filter element.

　　Function:　The air entering the engine cylinder is carefully filtered to ensure that sufficient and clean air enters the cylinder. Whether it can be kept clean and unobstructed is related to the life of the engine.

　　Replacement cycle:　Under normal circumstances, the vehicle should be replaced once every 10,000 kilometers or about half a year, and it is best to replace it once every three months when the fog or catkins are serious.

　　Harm of not replacing in time:　If the replacement cycle is exceeded, the filtering performance of the air filter element will deteriorate, and the particulate pollutants in the air will directly enter the cylinder, which will easily produce carbon deposition, leading to a decrease in power and an increase in fuel consumption, which will shorten the life of the engine for a long time.

　　Location:　Open the storage box of the co-pilot of the vehicle and take off the baffle to find the air conditioning filter. (except for a few models. )

　　Function:　Filtering the air that enters the interior of the carriage from the outside can improve the cleanliness of the air (filtered substances refer to impurities contained in the air, such as tiny particles, pollen, bacteria, industrial waste gas and dust, etc.), which can provide a good air environment for people in the car and protect their health.

　　Replacement cycle:　Under normal circumstances, it is recommended to replace it once every six months, or it can be decided according to the external environment of driving. When air conditioners are often used in winter and summer or during the period of high smog, the replacement cycle can be shortened appropriately.

　　Harm of not replacing in time:　If the replacement cycle is exceeded, the air conditioning filter element will lose its filtering effect if it absorbs a large amount of impurities, which will lead to the breeding and reproduction of bacteria over time, seriously affecting the health of passengers in the car.

　　Seeing this, riders should be able to easily distinguish between air filter and air conditioning filter! Of course, they are so important that their maintenance or purchase can not be ignored.

　　At present, air pollution in many cities in China is serious, and air filters and air-conditioning filters are prone to blockage, which is harmful to health, so we must pay attention to cleaning or replacing them in time.

　　How to judge whether the air filter should be changed?

　　1. First of all, we must observe and carefully look at the air filter itself, whether it is dark or black. If the air filter is obviously black, then at this time, this air filter should be replaced.

　　2. Generally, the air filter that is about to break will be deflated. If it is found, it needs to be replaced.

　　3. The third point is maintenance. If there is a lot of dust around the air filter, then we need to clean it at this time. If the effect of the filter is still not good after cleaning, please replace it in time.

　　How to judge whether the air conditioning filter should be replaced?

　　1. If the air conditioner has been turned on to the maximum gear, but the air output for cooling or heating is still very small, if the air conditioning system is normal, the reason may be that the air conditioning filter used has poor ventilation effect, or the air conditioning filter has been used for too long, so it should be replaced in time;

　　2. If the air blown by the air conditioner is smelly, the reason may be that the air conditioning system has not been used for a long time, and the internal system and air conditioning filter are caused by damp and mildew. It is recommended to clean the air conditioning system and replace the air conditioning filter.

● 新车介绍

　　外观方面，传祺M8宗师系列的设计可以说已经达到了很高的水准，E9就是在这个基础上打造，不过它采用了新的 “鲲鹏展翼”设计主题，横向的布局加上羽翼式大灯，确实有展翼的气势。细节上，前脸横向六条格栅，两条上下方的饰件，再加一条灯带横贯灯组，竖向单侧五条灯带，“横九竖五”就是九五之尊。然后这样的横条辐有点无边界设计的感觉，没有那种具象的大嘴，就更有新能源的气质。

　　来到侧面，也基本是M8宗师系列的轮廓造型，侧裙的包围有细节变化，然后比较明显的变化则是车窗上沿的镀铬饰条，E9在后部做了造型，并且没有像向下转折，所以视觉上就完全是悬浮车顶的造型，整个车窗感觉就像一整块过来的。车尾与M8保持一致，相信每个人看到这个“时空之门”尾灯都会被它的霸气震慑一下，变化的小地方也样是下包围，会更简洁利落。

　　内饰方面，四平八稳且端庄大气的布局，材质搭配也够丰富，然后E9也同样提供多种风格色彩搭配，“云山珠水”的雅致，“歌剧殿堂”的浪漫。传祺E9前排就有三块屏幕，12.3英寸组合驾控仪表+14.6英寸超大悬浮式中控屏+12.3英寸副驾娱乐屏。在ADiGO系统和雅马哈音响的组合下，有丰富的应用，也有悦耳的音质。

　　对于最重要的第二排，屏幕也得安排，拥有15.6英寸独立影音系统，然后MPV最尊贵提醒则是座椅，半苯胺高级真皮面料，各种电动调节，“一键SPA”模式的按摩功能，还有头枕音响，享受就对了。

　　传祺E9作为广汽传祺MPV家族全新插电式混动产品，搭载自研2.0TM混动专用发动机，GMC 400混合动力专用变速箱和25kW·h电池包，WLTC工况综合续航超1000km，WLTC馈电百公里油耗6.05L，0-100km/h加速时间8.8秒。

　　The 2.0T plug-in hybrid engine has a maximum power of 140kW, a maximum torque of 330N · m, and a maximum thermal efficiency of 40.23%. It also has many advanced technologies. In fact, compared with many plug-in mixers based on 1.5T, 2.0T is obviously more fierce. Then the GMC 400 hybrid special gearbox adopts the second-generation GMC (P1 + 2AT + P3) scheme, and the two-speed DHT can also better balance low-speed and high-speed operating conditions. Power and energy consumption are also better.

　　Then the battery part, GAC’s magazine battery is safe enough, 25kW · h pure electric battery life under WLTC conditions is 106KM, of course, this battery life is fair, but the electrical function is comprehensive, supporting fast charging, slow charging, external discharge function, so the use of electrical equipment, outdoor power scenarios can satisfy you.

Editorial opinion

　　Looking at the current MPV market, the Trumpchi M8 family has seven or eight thousand units per month, which is not a big problem, while the sales volume of the D9 has exceeded 10,000, so there is actually a lot of room to go up and go to new energy. This is the purpose of the official Trumpchi E9. Based on the good strength of the M8 Grandmaster series, coupled with the latest generation of intelligent electric technology of GAC Trumpchi, the plug-in hybrid version E9 should have a good performance.
