In 2013, nine bureau-level cadres in Wuhan were investigated-corrupt officials were not far away.

Yesterday, the Wuhan Municipal Commission for Discipline Inspection held the fourth plenary (enlarged) meeting of the 12th session. It was reported at the meeting that in 2013, the discipline inspection and supervision organs at all levels in the city investigated and dealt with 9 bureau-level cadres, punished 626 party member cadres who violated discipline, and transferred them to judicial organs for handling 70 cadres.

According to statistics, from 2010 to 2013, a total of 2,112 party member cadres were put on file for investigation, including 25 bureau-level cadres and 339 department-level cadres. The trajectory of these corrupt officials is alarming and thought-provoking.

Xie Gongzhuo: There is no hope of getting promoted and getting rich.

On January 23, 2013, Xie Gongzhuo, former executive vice minister of the Propaganda Department of Wuhan Municipal Committee, just celebrated his 54th birthday. And a pair of handcuffs became his late birthday present.

In January 1997, Xie Gongzhuo was appointed as Deputy Secretary of Hannan District Committee. In the following more than 10 years, he served as the district head and secretary of the district Committee. "I haven’t been recognized by the organization for so many years. I think I should have a rest, so I am a little relaxed about myself." Xie Gongzhuo believed that his career was hopeless, and he started from "loss" to "out of control".

By contracting projects for enterprises in Hannan District, Xie Gongzhuo has received 300,000 yuan from a property management company, 50,000 dollars from a sewage treatment company, 100,000 yuan from a health care product company and 50,000 yuan from an industrial development company.

The longer Xie Gongzhuo stayed in Hannan, the more frustrated he became and the crazier he became in collecting money.

In April 2006, a real estate company acquired 200 mu of land in Hannan to build a factory. Hannan District Committee decided that the price of the expropriated land should not be less than 35,000 yuan per mu. The person in charge of the company immediately asked Xie Gongzhuo for help and asked for a price reduction. Xie Gongzhuo ignored the decision made by the district party committee. He personally came forward to coordinate, which broke the "example" of the district Committee and adjusted the land price requisitioned by this company to 25,000 yuan per mu.

Xie Gongzhuo not only can’t refuse the temptation of money, but also attaches great importance to official career. Thinking that he was "marginalized" became his increasingly heavy heart disease. In the last days when Xie Gongzhuo was in charge of Hannan, he became a "mobile phone secretary". He can’t be found in the office building, whether it’s the arrangement work or the staff asking for instructions, almost only by mobile phone.

In September 2008, Xie Gongzhuo was transferred to the position of executive deputy director of the Propaganda Department of the Municipal Party Committee "with mixed feelings". After his arrival, his mental state was even more depressed. Usually, except for the meetings attended by the four leaders in the city, other meetings that should have been attended are "done by others", and even the female boss who knows him drives him out to eat and drink in a luxury car during working hours.

His figure appears more and more in karaoke bars, dance halls, bars and sauna clubs. Due to misconduct, a boss once threatened Xie Gongzhuo in the bath center: "Your activities here have been videotaped, so you should be honest."

In October 2009, the person in charge of a company gave a banquet to Xie Gongzhuo and his wife Liu 500,000 yuan after dinner. This is the biggest bribe he has ever received. He was afraid of being investigated and dared not deposit it in the bank.

Before 2006, Xie Gongzhuo put money in the office; With the increase of the amount, he bought a suitcase and put it in his mother’s house; In the second half of 2011, I bought a small safe; At the beginning of 2012, it was replaced by a medium-sized safe. When the case handlers opened the safe, there was RMB 1.12 million in it.

On August 20, 2013, Xie Gongzhuo was accused of taking advantage of his position to accept bribes of RMB 1.67 million and USD 100,000 from 13 companies and individuals. The Municipal Intermediate People’s Court sentenced him to 10 years and 6 months’ imprisonment.

Zhang Huojin: The work notes are full of mahjong tips.

When the case handlers picked up the work notebook of Zhang Huojin, the former vice chairman of Xinzhou District CPPCC, they found that it was full of pages of mahjong secrets.

In 2006, Xinzhou District was re-elected. At that time, 43-year-old Zhang Huojin was eager to enter the leadership team of the district government, but failed to do so. Zhang Huojin feels that he is a place-level cadre in the district, and he is at the top. So I relaxed myself and gambled around.

In 2011, Zhang Huojin was promoted as the vice chairman of the District Political Consultative Conference. He was dissatisfied and thought it was a "idle job". He had a job and no right, and his heart was even more lost. He just wanted to gamble and win money.

During his tenure as director of Xinzhou District Civil Affairs Bureau and vice chairman of the District Political Consultative Conference, Zhang Huojin went to Macau to gamble privately for 17 times. In order to repay gambling debts, he used his position to misappropriate more than 2 million yuan of public funds.

Zhang Huojin also directly intervened in the construction of the social welfare home of the District Civil Affairs Bureau and the maintenance works of the office building of the District Civil Affairs Bureau. He violated the bidding regulations, contracted the unit project to Luo, and received 700,000 yuan in money and goods. Luo’s wife, Xue, not only lent Zhang Huojin "code money" in different amounts many times, but also borrowed money to repay Zhang Huojin when he embezzled public funds and could not repay it.

At present, Zhang Huojin has been transferred to the judicial organs for handling.

Hu Qinhua: Make real efforts for my aunt’s profit.

On February 14th, 2012, on Valentine’s Day, the former head of Wuchang District, Hu Qinhua, and his wife, Chen Mou, were both disciplined.

This "husband and wife file" has been collecting money together for more than ten years.

In the second half of 2000, a unit building in Wuhan was ready for renovation. Hu Qinhua’s wife, Chen Mou, asked him to come forward and hand over the project to a Shenzhen company operating in Han, because its boss is her good friend.

With a greeting, the company successfully received the renovation project with a total price of 30 million. As a token of gratitude, General Manager Wang gave Chen Mou 300,000 yuan in two installments according to 1% of the total project amount.

Hu Qinhua knew, not only did he not stop it, but said, "The market outside is all three points." Wang was helpless and had to add another 600,000 yuan in benefits.

In February 2009, Zhang, the owner of a real estate company, gave Hu Qinhua’s wife a valuable necklace, which Hu Qinhua pushed away. However, he said meaningfully that his family is still doing business, so it is ok to "take care of" it in the future. Hu Qinhua’s family refers to her aunt who runs two advertising companies.

At this time, although Zhang did not have any advertising needs, he still signed an advertising contract of 380,000 yuan with his aunt.

At the beginning of 2011, a construction site of the company needed to be fenced, and Zhang entrusted the construction unit to sign a light box and inkjet enclosure contract with Sister Hu Qinhua. And this contract worth 630 thousand yuan is only used to write a few advertising slogans on the enclosure.

A few months later, Hu Qinhua visited the company and pointed to the other side of the fence with advertising slogans, stressing: "The advertising is doing well, and it needs to be rectified there." Zhang got the message, and an advertising contract of 1.386 million yuan once again fell into the hands of Aunt Hu Qinhua.

From March 2007 to May 2011, during his tenure as the head of Qiaokou District, Hu Qinhua greeted five companies successively, and asked his aunt to undertake advertising business of 4.185 million yuan, with a profit of 1.625 million yuan.

On February 28th, 2013, Wuhan Intermediate People’s Court held a hearing on Hu Qinhua’s case. According to the prosecution’s allegations, from 2000 to 2012, when Hu Qinhua was the deputy head of Hannan District, the head of Qiaokou District and the head of Wuchang District, he personally accepted bribes totaling more than 1.22 million yuan and a large amount of foreign currency, and together with his wife Chen Mou, he took bribes of 900,000 yuan.

Four major factories in Xpeng Motors

Four major factories in Xpeng Motors

Xpeng Motors currently has four factories, namely Haima Zhengzhou No.3 Factory, Guangdong Zhaoqing Factory, Guangdong Guangzhou Factory and Hubei Wuhan Factory. Among them, the third factory in Haima Zhengzhou has stopped production, while the other three factories are all in production or under construction.

The first isHaima Zhengzhou 3 rd factoryThe factory was rebuilt by Xpeng Motors and Haima Automobile, but with the cooperation terminated on December 31st, 2021, the factory has stopped producing Xpeng Motors. The factory is located in Zhengzhou City, Henan Province.

Followed byGuangdong Zhaoqing factoryThis factory is the first self-built factory in Xpeng Motors, located at No.33 Longhu Avenue, Sihui City, Zhaoqing City, Guangdong Province. The factory started construction in 2017, and started production in May 2020 after obtaining the production qualification. At present, it is the only main production base under Xpeng Motors, mainly responsible for producing Tucki G3, P5, P7, G9 and other vehicles.

The third one isGuangdong Guangzhou factoryThis factory is the second factory in Xpeng Motors, but it is not entirely self-built. In fact, it was established in cooperation with Guangzhou Development Zone Financial Holding Group.

The initial planned production capacity is 100,000 vehicles per year, and it is expected to be put into production by the end of 2022 or the first quarter of 2023.

Creating a Higher Sense: Interpretation of Roewe MARVEL X Design

  [Design Decoding] Driven by favorable policies and future development trends, more and more enterprises have begun to enter the team of new energy vehicles. In addition to the brands we are familiar with, Weimar Automobile and so on, there are many enterprises in the embryonic stage, and these new vehicle-making enterprises not only help the rapid development of new energy, but also promote the traditional car enterprises to further develop new energy. Today, our protagonist is the high-end pure electric vehicle launched by the traditional OEM. In the future, it will cut into the market segment to meet the needs of consumers for high-end SUVs.

Home of the car

  Different from the pure electric vehicles such as ERX5 launched by Roewe before, MARVEL X is not a pure electric vehicle based on the replacement of powertrain for gasoline models, but a completely independent new model. Moreover, not only MARVEL X, but also MARVEL owned by Roewe will have a series of new energy vehicles focusing on the mid-to-high-end market in the future. From the design idea of this MARVEL X, we can see the difference between this MARVEL series and ordinary Roewe pure electric vehicles in the future.

● Appearance and coincidence 90%

SAIC MARVEL X 2018 Basic Model

  MARVEL X was designed by the SAIC design team led by Shao Jingfeng, the design director of SAIC. At present, Roewe’s flagship pure electric SUV almost completely retains the previously released concept car in design. It is understood that the appearance overlap between the production version and the concept car is as high as 90%, so the MARVEL X in front of us looks very avant-garde.

SAIC MARVEL X 2018 Basic Model

SAIC MARVEL X 2018 Basic Model

  At the beginning of MARVEL X design, the team led by Shao Jingfeng found the right direction and positioning. As the representative of Roewe brand pure electric SUV, it will enter the eyes of consumers. Different from the previously released pure electric vehicles such as ERX5 and Ei5, it will face the mid-to high-end market. The specific market demand throws them a difficult problem, and how to build a car that is more in line with this market demand is what this team needs to do. Then, after numerous brainstorming, they finally determined three key words to achieve this goal: strengthening brand recognition, emotional design and shaping a sense of high quality.

SAIC MARVEL X 2018 Basic Model

SAIC MARVEL X 2018 Basic Model

  After the evolution of RX5, RX3 and i6, the rhythm design of Roewe brand has been well received by consumers, while the overall design idea of MARVEL X continues the concept of rhythm, and we can see the familiar Roewe from the design of the front of the car. The huge wingspan grille has been preserved in this pure electric SUV, and the front grille shape has not been cancelled like other new energy vehicles. This design style seems to make the whole car more powerful. The addition of light arc lights outside the grille not only enhances the visual effect, but also further deepens the brand image. Together with the "Arrow Feather", it will have a deep impression at first glance.

SAIC MARVEL X 2018 Basic Model

  In the design of MARVEL X, there are also many similar design elements on RX5 and RX3, such as the waistline running through the car body and two arcs on the front and rear wheel arches, so that the sides will not look too rigid. The design of the rear of the car is not the same as that of the previous Roewe models. First, the license plate frame is moved down to the rear enclosure, and the rear of the car looks simpler. It also has a waist-closing design, and the lower plate looks quite solid.

SAIC MARVEL X 2018 Basic Model

SAIC MARVEL X 2018 Basic Model

  We can see that in MARVEL X’s design language, dynamic modeling occupies a key position. MARVEL X, as an SUV, has a lower body than traditional SUVs, and the identity of pure electric vehicles also gives designers more room to play. Its visual center of gravity is more backward, and the low-cut, slender body with a small proportion of the rear window creates a visual feeling of diving forward. At the same time, the exaggerated surrounding decoration of the front and rear of the car also plays a role in increasing the sense of movement. However, this MARVEL X is more than just watching sports. In order to improve performance and fuel economy, its streamlined shape and optimized low wind resistance rearview mirror, together with the hidden door handle, have reduced it to 0.29Cd.

Analysis of the chassis of SAIC Roewe RX5, not seeking success but seeking nothing.

  [Aika car SUV channel original]

  Roewe RX5′ s monthly sales of 20,000 units can be said to have earned enough profits and eyeballs for SAIC. It must be said that SAIC’s accumulation in styling design in recent years has brought exquisite appearance to RX5, and another group of young people in the same R&D center have also created many topics for RX5 human-computer interaction system with their unique ideas. What kind of world is hidden under such a car that shines brightly?

RX5 chassis analysis

  The vehicle we shot this time is Roewe RX5 20T two-wheel drive Internet Smart Edition, equipped with a 1.5L turbocharged engine and a 7-speed dual-clutch gearbox, driven by front wheel drive.

I. Overview of Chassis

RX5 chassis analysis

  Similar to the chassis structure of many compact SUVs on the market, RX5 adopts McPherson independent front suspension and E-type multi-link independent rear suspension. The chassis of RX5 has no redundant guard plate to protect the parts, from which we can also see that it focuses on the positioning of urban road conditions. However, through analysis, we can still find that RX5 is worthy of its price and people’s attention in chassis structure and materials.

RX5 chassis analysis

  RX5 adopts a frame-type front subframe, which can not only improve the overall strength of the front of the car body, but also make the force on the front of the car body more uniform.

RX5 chassis analysis

  RX5′ s two-wheel drive vehicle adopts a rear subframe similar to H-shape, and almost all the connecting rods on the rear suspension apply force to the rear subframe, thus reducing the direct impact of suspension on the vehicle body. The rear subframe of RX5 four-wheel drive vehicle is structurally different from that of two-wheel drive vehicle.

Second, the front suspension analysis

  RX5′ s McPherson independent front suspension is really nothing too surprising. Indeed, for most cars under 200,000 yuan on the market, it is too ordinary to adopt McPherson front suspension. However, the details of the RX5 front suspension still have its own special features.

RX5 chassis analysis

RX5 chassis analysis

RX5 chassis analysis

  On the whole, the front suspension adjustment of RX5 tends to be comfortable, and the damping spring can filter out most small vibrations, but for some relatively large vibrations, the response of the spring is a bit stiff. Usually, the relatively large vibration will be directly transmitted to the car, which makes people somewhat unprepared. However, thanks to this adjustment, RX5 has a good performance in controlling roll.

Third, the rear suspension analysis

  RX5 adopts E-type multi-link independent rear suspension, which is also quite common in the same class. This multi-link suspension adopts a vertical and three horizontal conventional structure, and most of the connecting rods are stamped from steel plates, and there is not much innovation in the arrangement of connecting rods.

A comprehensive analysis of Angkewei, Buick’s new medium-sized SUV in cross-level competition

speed up apply the brakes oil consumption second rice rise Rejuvenation overnight: a test of Buick Angkewei s two-wheel drive Evaluation Editor-Li Qiaochen:

After the overall rejuvenation of Buick Angkewei S, the whole car naturally becomes more lively. Compared with the cash, Angkor simply can’t see any inheritance relationship between the two. The driver-led style of the interior also shows that Buick designers just want to build a medium-sized SUV model that is no longer old-fashioned. The dynamic performance is very surprising, and the adjustment of the chassis is somewhat sporty. With sufficient power reserve, the power output can always keep up with your driving rhythm.

Evaluation editor:

Buick has gradually become younger in recent years, and this Angkor S is no exception. The shape of a medium-sized SUV can be made so low, and even the illusion of a station wagon appears, which is a change of Angkewei’s mature and stable image. Although it is mainly two-wheel drive, the driving experience in the city has little effect. The light and even slightly sensitive throttle and solid chassis will definitely make people who love driving fall in love with this SUV.

Evaluation Editor-Hong Bingqing:

As can be seen from the appearance design, this is a "non-mainstream" SUV, and it is a farewell to Buick in everyone’s inherent thinking. The exterior decoration of this sports model is in place, but it is not out of line. The interior did not stick to stereotypes, and it was very bold to play a driver-centered design. Since it is mainly a two-wheel drive model, the more sporty driving style of Angkewei S becomes reasonable. It is a medium-sized SUV, but driving it in the city will not be boring.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

[Original Truck House] can be said to be the most familiar strange truck parts for card friends. As we all know, the air filter can purify the air entering the air, so most card friends are very happy to replace the air filter in time, but the air filter is not changed as often as possible.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

What problems will the frequent replacement of air filter cause to the engine? Can the air filter be used for scrapping and then replaced? Today, we will simply discuss these issues with card friends.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

Air filtration, that is, it consists of two parts: filter element and casing. The filter element is the main accessory, which plays the role of gas filtration, and the casing is the shell that provides protection for the filter element. The main function of air filter is to filter the air entering the engine and purify the air quality.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

The air contains a lot of impurities, such as dust and sand. If it directly enters the engine chamber without purification, it will accelerate the wear of the engine and even cause the phenomenon of "cylinder pulling". The air that enters the engine after being filtered by the air filter is relatively clean and can delay the occurrence of these problems.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

As a kind of filtering device, the air filter is insignificant, but it has a light position compared with engines and other accessories. If the air filter is not filtered, natural air will directly enter the engine working room, which will lead to engine wear. If the air filter is not maintained for a long time, the filter element will be covered with dust, which will hinder air circulation and make the engine work abnormally.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

The serious blockage of air filter will increase the intake resistance, which will lead to the decrease of engine power. At the same time, because of the increase of air resistance, it will also increase the fuel consumption when the engine is working, which will worsen the engine running state and increase fuel consumption. Therefore, ordinary card friends also need to maintain the filter element of air filter.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

Since the role of air filter is so important, and if it is not maintained in time, it will also cause problems such as increased engine fuel consumption and decreased engine power, so can the filter element be replaced frequently? So that the engine can always be in the best working condition? The answer is no.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

In addition to filtering the air, the air filter is also responsible for the air intake required by the engine. Inferior filter element, in order to reduce the cost, the quality of the materials used will be poor, which will lead to too large or too small air intake, and even fail to play a filtering role, which will directly lead to abnormal wear and tear of the engine.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

So how about changing the air filter that meets the standard frequently? In order to play a good filtering role, the air filter element will have a large number of irregular gaps on the surface of its filter paper, but dust, sand, etc. are also large and small, so it is impossible to become completely pure air after being filtered by the filter element, and it will still contain some impurities.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

In order to distinguish the filtration degree of the filter element, the concept of "initial interception efficiency" is introduced, which is usually expressed by percentage (%). If the initial interception efficiency is 99.95%, it means that the filter element can filter out 99.95% impurities in the air at the initial work, but 0.05% impurities cannot be filtered out, which will enter the engine with the filtered air.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

Corresponding to the initial interception efficiency, there is also a "life cycle efficiency", which is also expressed by percentage (%). As the filter is used for a long time, the dust accumulated on the surface of the filter paper will gradually increase, which will block the gap between some filter paper fibers, which means that the pores between fibers become smaller, and the interception efficiency of the filter element will increase compared with the initial state.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

So which interception efficiency is more advantageous, the initial interception efficiency or the whole life efficiency? An experiment was conducted in Truck House. The initial interception efficiency of an air filter can reach 99.81%, while its whole life efficiency can reach 99.98%. The difference between the two filtering effects is about 9.5 times.

That is to say, if the new air filter is used to enter the air in the engine, the impurities in it will be 9.5 times more than those in the air in the old air filter. Before, we have learned what harm will be caused to the engine by more air impurities entering the engine, so this is also the reason why the air filter element cannot be replaced frequently.

If the air filter is replaced too frequently, be careful to aggravate the wear of the engine.

For the air filter, you can’t change it frequently, and you can’t always use a new air filter, and you can’t always change it, so you can’t get the filtering effect. So when is the best time to change the air filter?

Under normal circumstances, the effective service life of general air filters is about 20,000-30,000 kilometers, but the service life of air filters will be different due to the actual working conditions of the car and the engine, which will be mentioned in the maintenance manual attached to the car. Card friends can choose to maintain or replace the air filter at a suitable mileage according to their own situation.

●  Postscript

Although the air filter is unremarkable, it plays an important role. It can’t be replaced with a new filter frequently, and it can’t be replaced all the time. When the card friends maintain and replace their models, it is best to follow the manufacturer’s maintenance manual, or according to the advice of the technicians in the maintenance station, so as not to cause immeasurable damage to the start.

On May 21st, Yu Chengdong, CEO of Huawei’s consumer business, revealed:"As soon as this fall, at the latest next spring, Huawei’s own OS will probably be available.. "

In fact, the domestic mobile operating system has been tried by many manufacturers before. The giants include Baidu (BIDU.US) cloud OS and Tencent (00700)TOS, and the entrepreneurial team once had a little heart OS and Le Frog OS. And the most brilliant achievement belongs to Ali:

At the end of 2015,BABA.US) YunOS surpassed WP to become the third largest mobile operating system in China with a market share of 7.1%., second only to Android and iOS.

Now, times have changed, and Huawei HarmonyOS, burdened with the expectations of Chinese people, can make a scene like Wukong mentioned in the promotional film and fight its way out in the rivers and lakes of the mobile phone operating system?

In the short film Wukong, the little boy, obsessed with the Monkey King, is bent on going to see the Monkey King’s movie in the big city where "there is only one way to go over the back mountain and two more mountains, and it takes one night by car". He goes out alone, encounters a series of "adventures" and finally arrives at his destination in rags.

Some netizens commented that the spirit of the little boy and the spirit of Wukong are in the same strain, and the shadow can also be seen in Huawei.

Huawei officially released the film on May 23rd.

At the same time, Huawei announced that its "spare tire" had turned positive, and its self-developed Hisilicon chip and self-developed operating system "HarmonyOS" attracted much attention. This short film also triggered speculation about HarmonyOS system.

Huawei rarely makes statements to confirm or completely deny the rumors of HarmonyOS system. Ren Zhengfei, founder of Huawei, said in an interview with national business daily on May 21st:

We can do the operating system, but it is not necessarily a substitute for others.Because we also need it in artificial intelligence and the Internet of Everything, but I don’t know exactly which ones are used and which ones aren’t. "

At the same time, he did not disclose whether HarmonyOS has been used in a small scale within Huawei.

Compared with Huawei’s low profile, "HarmonyOS" system keeps making new progress. On May 24th,The website of China National Intellectual Property Administration Trademark Office shows that Huawei has applied for the "Huawei HarmonyOS" trademark.. The application date is August 24, 2018, the registration announcement date is May 14, 2019, and the exclusive permission period is from May 14, 2019 to May 13, 2029.

Then, on May 29th, it was reported that a few days ago, Huawei submitted a trademark application for "HUAWEI ARK OS" to the European Intellectual Property Office, and "ARK" means "Ark" in English.

At the beginning of June, it was reported from the media that Huawei has started to test the mobile phones that will be equipped with HarmonyOS system, and the number of mobile phones in the test stage has reached one million. At the same time, Huawei also released the interface picture of HarmonyOS system, which is very similar to the current Huawei EMUI. The function arrangement, status bar, font layout and key color matching are almost identical.

On June 3rd, Huawei told N+ Finance that "we haven’t heard of it at all, so we can’t comment" on the rumor of testing HarmonyOS system on 1 million mobile phones.

It is understood that Huawei has been planning its own operating system "HarmonyOS" since 2012, aiming to become a substitute for Google’s Android system.

As for HarmonyOS, it is reported that the operating system has been greatly optimized for Linux (open source) and has been used in Huawei mobile phones (security part).

Combined with such news, Huawei’s HarmonyOS system comes to the fore. Tim Watkins, vice president of Huawei’s Western European market, has previously confirmed to the media that Huawei has been developing an operating system and will launch it soon.

Operating system is the soul of smart phone. As far as the current market is concerned, operating systems are mainly divided into two schools.They are Apple’s iOS system and Google’s Android system, which have a market share of 99%.

Since Apple’s iOS system is only for its own use and not open to other mobile phone manufacturers, Android system has become the only choice for many mobile phone manufacturers in China. Huawei’s EMUI system, Xiaomi’s MIUI system and vivo’s Fun touch OS system are all deeply developed based on Android system.

Wei Yongming, CEO of Feiman Software, wrote an article in 2012, "Why does Huawei Alibaba have to engage in an" independent "operating system? What is the soul of the operating system? ",the article said that taking Android as an example, the operating system open source license constraint is very loose, but:

"Google has certainly accumulated a large number of patents in the process of developing Android, especially Dalvik virtual machine and Java class library, and these patents are above the copyright and license of the software. In other words, if you derive a branch from the existing Android,If you want to sell the software running this derivative version of Android on your mobile phone, Google can immediately take out a patent stick to limit you."

According to Yu Chengdong’s description of HarmonyOS system, all Huawei mobile phones will be equipped with self-developed OS system in the future.Huawei’s self-developed operating system has opened up electronic devices such as mobile phones, computers, cars and tablets, and has been able to support a new software ecosystem for Huawei.

However, at present, the operating system has been occupied by Android and iOS. In order to occupy a place in Huawei’s HarmonyOS system, the first thing to be solved is the problem of software compatibility. After all, no company will adapt software for a system that is not used by many people.

In the research report "From Operating System to Chip-Counting is still stuck in the neck field (I)" released by China Merchants Securities in August 2018, it is pointed out that compared with foreign countries, the technical development of operating system is not a difficulty, nor is it a core factor restricting the development of domestic operating systems.

"The main reason why it can’t occupy a place in the market is that the domestic operating system lacks the ecological environment for high-quality applications."

At present, there are some doubts about the expansion of Huawei’s HarmonyOS system. Before Huawei’s "HarmonyOS", other domestic manufacturers tried to develop their own operating systems, but they didn’t really grow up in the end.

For example, Alibaba Yun OS once occupied 7% of the domestic mobile phone operating system market share from 2014 to 2015, which was also the "peak moment" of the domestic mobile phone system, but then the market share declined rapidly.

Yesterday, Xiang Ligang, the founder of Feixiang.com, expressed another view to N+ Finance. In his view,Huawei has shipped 200 million mobile phones this year, and Apple also has 200 million mobile phones. "Apple’s ecology can be done. Why can’t Huawei be an ecology?"

He said that the outside world’s doubts about Huawei HarmonyOS are mainly at two levels. First, many operating systems, including Windows, have not been done; Second, many people may not develop applications for Huawei systems.

Xiang Ligang said that Windows appeared earlier than Android, and then Android overtook it. The reason why it is not done well is becauseWindows is unfriendly to developers, with poor interface experience and poor interaction ability.

"Windows also charges mobile phone manufacturers, and of course it doesn’t do well. Huawei certainly does not have the problem of charging for its own use.Huawei’s understanding of the operating system has been very profound. And made a new compiler, which is compatible with Android applications.So it’s easy to build HarmonyOS, and I don’t think there is any problem. "

"Many people may not support Huawei’s application.But if Huawei sells hundreds of millions of mobile phones a year, why not apply it?If these applications are very difficult to do, then the current applications are Android, and they can be compatible by running the compiler once. "Xiang Ligang said.

Sun yanbiao, dean of the first mobile phone research institute, believes that the operating system mainly depends on the construction of ecology, and it takes time to build ecology. It took Apple four or five years to build its own ecology, and Android also took four or five years.Under the existing operating system, it will take two to three years for HarmonyOS to do it, and this time is inevitable.

"Why should Internet APP developers develop corresponding apps? This needs to be based on a large user base. What the new ecology often lacks most is the user group. Only by having a large user group can we make a profit, which is essentially a problem of Internet effect. In addition, the ecology that Huawei HarmonyOS needs to build is not only China, but also overseas, so it takes time. "

Sun Yanbiao emphasized that Huawei’s HarmonyOS system could not build a strong ecosystem in a short time, and the construction of this ecosystem was a slow process. "At that time, when Android was going to be an ecosystem, almost all mobile phones except Apple used Android’s operating system, but even in this case, it took almost four years for Android to sprout to rival Apple’s operating system."

Xiang Ligang also told reporters that after the release of the HarmonyOS system, it will change the market structure of global operating systems. HarmonyOS system appears after Android and Windows, and its understanding of operating systems is definitely deeper than that of Android.

"Huawei itself said that if you run it with a compiler, you can improve the efficiency by 60%. Android needs a virtualizer, and it doesn’t start the compiler from the bottom at all, while the HarmonyOS system starts compiling from the bottom, and the efficiency is definitely better than Android. " Xiang Ligang said.

In addition to Huawei, new news has also come from the operating system field.

On May 25th, the media revealed that KaiOS Technologies, the manufacturer of the third largest mobile phone operating system in the world, had received a $50 million financing in Series B..

In addition, ZTE is also developing a mobile phone operating system based on independent intellectual property rights. The industry believes that the operating system may show a diversified trend and is expected to usher in a new round of competition.

The latest news is that on May 31st, it was reported that Mate 20 Pro, which was previously removed by Google, was back, and it continued to support the latest Android Q Beta.

Earlier, Google’s parent company Alphabet announced that it would stop some cooperation with Huawei and erase the name of Huawei Mate 20 Pro on the Android Q Beta page.
