Xiaoai students have activated about 100 million devices, woke up 8 billion times, and lived 34 million in September. Xiaomi IoT has connected 132 million devices (excluding mobile phones and laptops)-this is the latest "connection" report card given by Lei Jun at this year’s Xiaomi AIoT conference.

IoT business is an important part of Xiaomi Valuation (Tencent multiplied by Apple’s market value) ridiculed by Lei Jun on the eve of listing. During the roadshow of Xiaomi’s listing, many investors generally believed that Xiaomi’s hardware should be benchmarked against Apple, and its software should be benchmarked against Tencent, so as to calculate the value of Xiaomi. IoT not only has a lot of diversion hardware on the Xiaomi ecological chain, but also relies on this foundation for Internet services and software with strong liquidity.

However, just as there is a huge gap between monthly activity and connected devices in the published data, how to keep users’ retention and activity has always been a problem discussed by people in the industry. Fan Dian, general manager of Xiaomi IoT platform department, is no exception. Although no relevant data is given, he said in an interview with Geek Park that in the future, AI and other ways will be used to maintain user activity.

"Xiaomi also needs enough equipment activation to reduce the unit R&D cost. An analyst who did not want to be named also said that active users have another meaning for Xiaomi. Obviously, people are curious about what the next step of Xiaomi IoT will be.

Expanding the service map is the first answer given by Xiaomi. At the AIoT Developer Conference, Xiaomi announced that it will cooperate with a "mysterious" guest-IKEA from December, and all the intelligent lighting products of IKEA will be connected to the IoT platform. In the future, it will be possible to control the intelligent lighting products of IKEA through Mijia’s App and Xiao Ai’s classmates.

Not only IKEA, Xiaomi also announced that it has reached a cooperation with All Seasons Hotel, and moved the scenes such as small love speakers and intelligent lighting to the upcoming All Seasons Hotel (Shanghai Hongqiao Center Store). In addition, there is a partner who can infiltrate users’ lives from the decoration. Love space.

At this point, Xiaomi’s service targets are not only the previous intelligent hardware enterprises, intelligent hardware solutions, traditional home appliance manufacturers, voice AI platforms, but also hotels, apartments and real estate.

The importance attached to the high-frequency scene of intelligent lighting was demonstrated by Xiaomi at the first IoT Developers Conference in 2017. At that time, as a strategic partner of Xiaomi, Philips Lighting proposed that by 2020, all new lighting products would be embedded with IoT technology to achieve "interconnection".

According to statistics, in a typical user’s home, there are 17 switches on average, and a typical user performs 25,000 operations on turning on and off the lights in a year. Whether it is Philips Lighting or IKEA, intelligent lighting, as the first cooperative product, is a good decision to cultivate user stickiness.

However, analysts’ views are slightly different. An analyst who was present believed that Xiaomi cooperated with these platforms because "AI and smart home are the trends. If we only make exquisite life cost-effective products, it is actually difficult for Xiaomi and Netease YEATION to open the gap. What Xiaomi is doing now is trying to empower traditional products intelligently, which will be more cost-effective at the same price or slightly more expensive. 」

After the deployment in the past few years, Xiaomi’s smart home has achieved "a little" results. So far, Xiaomi IoT has supported 2,000 devices, covering more than 200 countries, and 132 million smart devices have been activated (excluding mobile phones and laptops).

"In the future, Xiaomi may have to think about how to connect other friendly products to his own platform as much as possible, so as to control more devices through Xiaoai students, which can promote Xiaoai students faster and more widely, but this seems a bit difficult. Some analysts have raised their concerns about the future of Xiaomi.

However, Lei Jun doesn’t seem worried. He understood the truth of "making many friends and making few enemies" a long time ago.

"Xiaomi promotes the progress of IoT equipment, on the other hand, it has also caused some misunderstandings to the industry. Is it true that I can’t connect to Xiaomi’s IoT system without joining the Xiaomi ecological chain? I repeat, no. At the meeting, Lei Jun said, "Xiaomi’s determination to open up has not changed. I hope everyone can understand this. 」

As early as 2014, Xiaomi established an ecological chain department focusing on the incubation and cultivation of intelligent hardware, and established an ecosystem composed of more than 220 companies through investment and incubation, of which more than 100 companies focused on intelligent hardware and consumer products. Last year, Lei Jun officially announced that it would open IoT capabilities to all developers and serve more third parties. This year, Lei Jun once again stressed that as long as developers access Xiaomi’s ecological agreements and specifications, they can be connected with Xiaomi.

Lei Jun said that in the next 5-10 years, AIoT will be the core strategy of Xiaomi in the future. As the name implies, Wang Peng, senior product manager of Xiaomi IoT, proposed two ways to empower future AIoT developers. The first way is AI voice empowerment, and the second way is the Internet of Everything. The most practical example is the Zigbee protocol used in smart lighting cooperation with IKEA, which will also be open to all developers next year.　 　

Some research reports pointed out that Xiaomi has now accessed hundreds of millions of intelligent hardware devices, and the entire consumer Internet of Things has begun to take shape. Other hardware devices must access Xiaomi’s IoT platform if they want to interconnect with these hundreds of millions of devices. At the same time, the use of Xiaomi platform by developers can avoid high R&D costs, greatly reduce the threshold of hardware entrepreneurship, and at the same time, there are various support such as sales channels, which is a win-win cooperation.

The research report also predicts that in the future, the IoT platform will no longer be exclusive to Xiaomi and eco-chain enterprises, but will be a huge development platform, and Xiaomi will get a lot of service fees and a lot of data.

Regardless of whether the future development direction of MIoT (Xiaomi IoT) will develop in the secondary direction, the revenue performance of IoT is indeed getting brighter and brighter. According to Xiaomi’s financial report for the third quarter of fiscal year 2018, IoT and consumer goods business contributed 10.8 billion yuan to Xiaomi, up 89.8% year-on-year. The total revenue of the business in the first three quarters of 2018 reached 28.9 billion yuan, which exceeded the total revenue of IoT and consumer goods in the whole year of last year of 23.45 billion yuan.

132 million is a number mentioned many times at the meeting. This is a smart device that Xiaomi IoT has been activated so far, which means that Xiaomi IoT has become the world’s largest consumer-grade IoT platform. In the development of IoT, the privacy policies of various countries and regions are a challenge that cannot be underestimated in front of various developers.

The EU General Data Protection Act (GDPR), which came into effect on May 25th this year, is known as the strictest user data protection act in the history of the EU. According to the provisions of GDPR, enterprises must explain to users in a way that users can understand and accept before collecting personal information, and give users the right to withdraw the license agreement at any time. Companies that violate the regulations may face a penalty of up to 20 million euros.

Xiaomi’s experience will be a valuable asset for reference. As early as 2014, Xiaomi set up the Privacy Committee, and cooperated with TRUSTe (now renamed TrustArc) in California, USA, the world’s largest privacy authentication scheme provider, to carry out privacy protection related business. By 2016, Xiaomi has obtained the privacy mark of TRUSTe.

According to Liu Kai, senior product manager of Xiaomi IoT, MIoT’s current privacy policy is configured in accordance with the highest standard GDPR, and at the same time, corresponding policy adjustments are made according to local conditions. For eco-chain partners, MIoT launched a one-stop auditing system and product privacy mechanism tools. For example, the latter provided a standardized interface to help developers realize the demand of "user withdrawal agreement".

Privacy and security are twin brothers. With Google, Apple and other technology companies, and domestic home appliance giants have seized the market in the IoT field, IoT security issues are also coming to the fore. This year, Amazon Echo broke a news story. Echo recorded a conversation between a couple living in Oregon and sent it to contacts in the address book. As Xiaomi IoT Liu Daokuan said, "IoT security is a big deal when it happens. 」　

Before "AI+IoT" became Xiaomi’s new growth engine, Liu Daokuan said that Xiaomi should first make MIoT safe. Xiaomi has a relatively complete security infrastructure and confident security protocols (Wi-Fi, BLE, Zigbee, NFC security protocols), and these successful experiences will be solidified in the form of SDK and provided to developers.

The Internet of Everything is a huge territory. Although we can’t predict the end of the arrival, fortunately, some people have started to take the lead.

The following is a record of Lei Jun’s speech:

Lei Jun: Good morning, ladies and gentlemen! The popularity of our Xiaomi developer conference is far beyond imagination. Just now, I believed that all the people were jammed on the way, and they should have felt the heat of the conference. When my colleague introduced me yesterday, he said that today there are not only many developers, but also Xiaomi’s very close partners. There are also many managers’ funds of investment companies and analysts in the securities industry. I said, why are there some analysts in the securities industry? They said that Xiaomi was listed, right? In fact, it shows that everyone is very, very concerned about IoT.

IoT, the whole industry has been doing it for more than 20 years. It is not a new concept. It has been done for so many years, and it has not made a breakthrough until the last five or six years. Why? In fact, it is very simple. The IoT for more than 20 years is based on PC. When Xiaomi started to do IoT, what was Xiaomi’s thinking? When we started to do IoT, we wanted to connect all devices with mobile phones as the core, so we stood at the forefront of this era as soon as we came up.

So when we see today, why is the IoT industry developing so fast today, much faster than before? I feel grateful to this great era, that is, the mobile Internet. After we made mobile phones, when we wanted to connect all the devices, we even thought about whether we could connect with TV well. The mobile phone becomes the remote control of the TV, and the TV becomes the display of the mobile phone. How can we seamlessly connect all the devices together? This is also the reason why most Xiaomi mobile phones are equipped with infrared remote control. So, that’s our idea.

When you have a preliminary idea, is IoT done? We still encountered many difficulties. Then, we even considered whether we can use the router as a device, because the router is a device that is turned on 24 hours a day at home, so we think of the router as a home server.

I remember that we made intelligent routers very early, in fact, in order to solve the interconnection problem of IoT. When we finish all this, will things be solved? Still not. In 2014, we set up a special department to make IoT connection module, embedded system, cloud service system and control center. When we provided the whole solution, this is a photo when we released it in 2014. At that time, we proposed to provide IoT intelligent module chips to our partners at the material price. I remember that at the beginning, a Wi-Fi connection module cost more than 60 RMB, and we soon got more than a dozen modules of IoT, which effectively promoted the intelligence of the equipment.

Of course, it is not enough to do this step. In 2014, we set up the Ecological Chain Department, which specializes in incubating and cultivating intelligent hardware. We have trained nearly 100 enterprises in the past time. Of course, today, I am very happy that many Xiaomi eco-chain enterprises have grown up or even listed, such as Huami and Yunmi this year, and they have successfully listed overseas.

Therefore, after so many years of deployment, Xiaomi’s IoT has made a little progress. Let’s take a look. Up to now, 2,000 devices have been held. By the end of the third quarter, the number of activated smart device connections was 132 million (excluding mobile phones and laptops). Maybe many people don’t have much idea about 132 million units, which have already ranked first in the world among consumer IoT devices. That is to say, whether it is Google or Apple, or the domestic appliance giants, the number of devices they have activated to connect to the Internet is actually a little far from Xiaomi.

What do I think Xiaomi has done on IoT at this moment to achieve these achievements? The most important thing is that Xiaomi attaches great importance to its partners, so we set up an ecological chain department five years ago to incubate intelligent hardware startups, and we have spent a lot of money to get to today step by step in this field. So I think today’s achievements are hard-won, and we will attach great importance to the alliance with our partners as in the past.

When IoT developed into this era, two years ago, I felt that artificial intelligence had made a huge breakthrough. After AI empowered IoT, the IoT industry showed a faster growth trend. I think there are many places where AI can empower IoT. Intelligent voice assistant is only a small link, but this link has brought a huge revolution to IoT equipment. What is the most obvious thing? It’s AI’s smart speaker.

Two years ago, Xiaomi regarded AI smart speakers as a key breakthrough in strategic commanding heights. Since its release in July last year, Xiaoai smart speakers have also ranked among the best in this field. I believe that most of you here should have used Xiaoai smart speakers. Why do I ask this question? Everyone says that there are at least forty or fifty kinds of smart speakers on the market, and many people think this thing is useless. Before July last year, we had a big internal debate. Everyone felt that the technology of artificial intelligence was not so mature. After the release of this product, perhaps the reputation was not so good. But to be honest, the response after the release far exceeded my imagination. Demand has been in short supply until May and June this year. Therefore, the whole smart speaker is well received than expected.

I communicated with Xiao Ai’s R&D department, and they even told me who is the most popular with Xiao Ai’s smart speakers? He is an empty nester and has no children at home. It is quite interesting to chat with Xiao Ai’s classmates. There is also a group of children who love to use speakers as toys at home. Of course, it is very important that the small love speaker can connect the smart devices of various IoT.

What is my own idea? I believe that control technology such as AI+IoT will be embedded in every device in the future. There may not be a special device called smart speaker, or smart speaker will become a very small device. This technology is embedded in every device. For example, I don’t need this page flipper. I just need to turn the page, and it will turn the page. I think in three to five years, every smart device may have the control module of AIoT, which will make the whole interaction very interesting. Our product department has also done a lot to embed AIoT technology into the equipment. For example, a small alarm clock released a few days ago actually has the intelligent technology of Xiao Ai’s classmates. In this case, the whole application will be wider and wider. I imagine that in a few years, the cost will be so cheap that every device will be easily connected to AIoT technology.

A month ago, I released Xiaoai’s Bluetooth speaker, which is very small, 49 yuan. Although it is small, the sound quality is actually excellent. A month ago, at the Xiaomi MIX3 conference, we released this little love Bluetooth speaker. I believe that this very easy-to-use voice interactive assistant will be embedded in every smart device in the future. Of course, I won’t talk about how AI empowers big data and other aspects. I at least think that the technology of AI smart speakers will be applied to the interaction of the whole smart device. We have embedded into these devices, which is Xiaomi Xiaoai’s smart alarm clock. More than 100 yuan can solve many problems.

Let’s take a look at what achievements Xiaomi’s Xiaoai classmate’s intelligent voice assistant has made in just over a year. A total of 100 million devices have been activated, because Xiao Ai is not only on smart speakers, but also on mobile phones, televisions and children’s story machine, and 100 million devices have been activated. Accumulated 8 billion awakens, I think this figure is relatively bullish, and the monthly activity has reached the scale of 34 million at the end of September. Therefore, everyone knows an intelligent system like Xiao Ai’s. In fact, the more you use it, the more intelligent it will become. They used to joke with me that there is as much intelligence as there are people. In fact, the more you use it, the smarter it becomes. Therefore, I believe that with such a large number of users, Xiaoai’s intelligence will become higher and higher.

So, what do I want to communicate with you today? But AI+IoT is the core strategy of Xiaomi. We have the earliest layout and the largest investment in this field, and I think our determination is also the greatest. Therefore, after five or six years of layout and five or six years of growth, we have developed to today’s scale. Looking at the next 5-10 years at this moment, it will always be the core strategy of Xiaomi.

And when it comes to core strategy, what advantages does Xiaomi have compared with other peers? It is the huge intelligent hardware ecological chain and the entire ecological environment that Xiaomi has formed. Moreover, we have an online Xiaomi Mall and a wired Xiaomi Home, and we also have a good marketing channel for IoT equipment. More importantly, we have a lot of users who highly recognize Xiaomi’s products, which will greatly improve the user experience and make the perception stronger and stronger after the whole IoT is empowered.

So, speaking of this, the most important thing for me today is to introduce the open ecology of Xiaomi’s AIoT. Throughout the open ecology, there are two Xiaomi and the relevant department heads at our conference to introduce the open ecology of AIoT. One is our IoT platform department, and the other is the head of Xiaomi’s artificial intelligence voice service department, which will give you a detailed introduction to the open ecology of AIoT.

What am I going to tell you? It is the determination of Xiaomi to cooperate. Everything is connected with wisdom. If we want to connect everything, I think the most important thing is the sincerity of cooperation. In the past five or six years, Xiaomi has come to this day because of cooperation and opening up. At today’s stage, the whole giant is extremely optimistic about the AIoT industry, and the competition is becoming more and more fierce. I think Xiaomi is more open than before.

In order to promote the opening up, we set up the Xiaomi Eco-chain Department, so that on the one hand, we promoted the progress of IoT equipment, on the other hand, it also caused some misunderstandings to the industry, saying that I can’t connect to Xiaomi’s IoT system without joining the Xiaomi Eco-chain? I think this is a big misunderstanding. We set up the Eco-chain Department to promote this matter, so that more people can effectively interconnect the equipment together. Therefore, as long as you access these protocols and specifications of Xiaomi, you can connect with Xiaomi’s equipment. Xiaomi’s investment is only to promote and strengthen this cooperation more effectively. This is what I want to explain to you today. Xiaomi’s determination to open up has not changed. I hope everyone can understand this.

Later, we will have two special reports to introduce our whole open ecology and open agreement. Thank you again for coming to our Xiaomi Developer Conference today. Thank you!

Editor-in-Chief: Sleeping Worm

Its grade represents its performance standard and quality grade, and it can reflect the key indexes such as fluidity, lubricity and cleanliness of engine oil at different temperatures. To judge the performance of engine oil, there are usually the following aspects:

Engine oil is generally divided into:, semi-synthetic oil,. The characteristics of these three oils are:

Mineral oil: low cost, although imported additives are added to mineral oil now, the service life is generally about half a year.

Semi-synthetic oil: It has good oxidation resistance, and it is a very good long-lasting engine oil, with a service life of about one year.

Synthetic oil: long service life, stable performance, but high price.

The "grade" of engine oil can be classified according to the standards of different international organizations and the attributes of engine oil.：

1. SAE (American Society of Automotive Engineers) classifies oil according to its viscosity value.

For example, SAE 5W-30, where W stands for winter, and the number before W stands for flow viscosity at low temperature. The smaller the value, the better the fluidity and the better the protection of the vehicle during cold start. The number after W represents the viscosity at 100 degrees, and the higher the number, the better the viscosity.

2，(）

According to the quality grade of engine oil, the higher the number, the higher the grade of engine oil.

A/B series: generally suitable for light-duty diesel engines.

C series: suitable for catalyst engines, C1-C4, and C3 or above are generally used for engines.

E series: heavy duty diesel engine.

3. API and ILSAC(& International Lubricating Oil Standards and Approval Committee) are classified according to the environmental protection grade of engine oil.

The series beginning with A and S represents gasoline engine oil, and the specifications are: API SA … Sn.

The series beginning with B and C represents diesel engine oil, with specifications of API CA……, CG-4, CH-4 and CI-4.

C, when S and C exist at the same time, it means that it is a universal type of gasoline and diesel.

D, the letters after S and C mean: from SA to SN. The farther back, the higher the environmental protection level. In-cylinder direct injection should be at least SN.

E, ILSAC adopts a higher engine oil quality grade evaluation standard, which requires further GF-5 specification evaluation of SN-grade engine oil passed by API. It is required to improve fuel economy, compatibility with exhaust system and prolong engine service life, so GF-5 standard is higher than SN.

Is the performance of engine oil good? How to judge?

It mainly depends on the recommendation of the vehicle manufacturer and the specific requirements of the engine. The following are some factors that are usually considered when choosing family car oil.

1. According to the user’s manual or maintenance guide of the vehicle, the engine oil type and annual grade suitable for this model are usually recommended, and it is most important to follow the manufacturer’s recommendation.

2. Different types of engines may require different types of engine oil. For example, high performance requires higher viscosity engine oil to provide better lubrication protection.

3, climatic conditions, according to the climatic conditions of your location, choose the appropriate viscosity, vehicles in cold areas need lower viscosity engine oil 0W-20, so as to be easy to start at low temperature and protect the engine. Vehicles in hot areas may need higher viscosity oils such as 10W-40 and 15W-50 to maintain lubricity at high temperatures.

4, environmental protection, some places with environmental protection requirements require the use of low-flow or low-phosphorus engine oil to reduce the environmental impact.

5, personal driving habits, often driving at high speed or heavy load, may need more advanced engine oil to provide additional protection.

6. With the increase of vehicle age, engine wear will increase. At this time, engine oil with higher viscosity or specific formula is needed to provide better protection.

Generally speaking, domestic users usually use 5W-30 or 10 or 10W-40 engine oil, but it is better to decide the appropriate engine oil according to the manufacturer’s recommendation and personal actual situation.

The above is my previous knowledge about engine oil.

———————————————–

The following are the precautions for oil change

1, be sure to buy genuine engine oil, machine filter.

2, it is not impossible to change yourself, the key is to save those wages and ignore them compared with their own safety. Except for those who like to do it.

3, don’t listen to those bloggers who make you, 20,000 kilometers of maintenance all right, according to the maintenance manual, it’s right, if they are so powerful, what do they need the factory’s auto engineers for?

4. Some fans asked whether the oil was put away or pumped well. Is it necessary to open another article on this?

5, the oil must be quantified, and it is not good to have more or less.

6, record the oil change mileage, in order to grasp the oil change time next time. Generally, there are some in the store, but some are lazy or forget, so you should remember to remind them.

　　The second "Belt and Road" international cooperation summit forum will be held in Beijing from April 25 to 27, with the theme of "jointly building the Belt and Road" and creating a better future.

　　The Belt and Road Initiative originated in China, and the opportunities and achievements belong to the world!

　　From 2013 to 2018, China enterprises directly invested more than 90 billion US dollars in countries along the route, and the turnover of foreign contracted projects in countries along the route exceeded 400 billion US dollars.

　　Central enterprises adhere to the Silk Road spirit of peaceful cooperation, openness and tolerance, mutual learning and mutual benefit, and strive to build the Belt and Road into a road of peace, prosperity, openness, green, innovation and civilization! Especially in the past two years, with the active participation of central enterprises, a number of cooperation in infrastructure fields such as transportation, energy and water resources have been promoted and implemented.

　　Xiaoxin summed up eight sentences when central enterprises participated in the construction of the "Belt and Road" initiative — —

　　Industrial Park: Building a Platform for Common Development

　　National business card: leading the international standard of the industry

　　Oil and gas cooperation: increasing the kinetic energy of economic growth

　　Scenery and fire: empowering partners to win together

　　Bridges and roads: promoting the interconnection of facilities

　　Airport and Port: Building an International Circulation Hub

　　Urban construction: building a landmark for a better life

　　People’s livelihood service: practicing the social responsibility of central enterprises

　　The Belt and Road Initiative is the largest economic platform for international cooperation provided by China to the whole world. While realizing their own development, central enterprises are also providing perfect infrastructure construction and economic and trade cooperation platforms for enterprises all over the world.

　　A typical case is Zhongbai Industrial Park.

　　Developed and operated by two central enterprises, China Merchants Group and SINOMACH, it is China’s largest overseas development area and the highest level of cooperation. With the joint efforts of China and Belarus, the park has become a landmark project of the Belt and Road Initiative. The total planned area of the park is 112.5 square kilometers. As of February 2019, the total number of enterprises entering the park has reached 43, with a total agreed investment of nearly 1.1 billion US dollars.

　　China Merchants Group has planned and constructed Djibouti Free Trade Zone.

　　Copy the domestic PPC comprehensive development model of "Qiangang-Central District-Houcheng", develop and build ports (DMP Wharf), parks (Djibouti International Free Trade Zone) and cities (commercial transformation of old port areas) in Djibouti, build a platform for China products, industries and services to "go global" and provide all-round support and services for China enterprises to "go global". At present, 40 Chinese and foreign enterprises have settled in the park, and more than 20 enterprises are registering their companies in the free trade zone.

　　China’s nuclear power and UHV are well-deserved "national business cards". In the past five years, this clean, high-energy and beautiful business card has been distributed all over the world, sending a steady stream of energy to countries and people along the "Belt and Road".

　　British nuclear power project

　　On September 29th, 2016, CGNPC signed a package agreement with the governments of electricite de france and the United Kingdom for new nuclear power projects in the UK, in which the Bradville B project will use the third-generation nuclear power technology Hualong No.1 with independent intellectual property rights in China. This is China’s largest investment project in Britain and Europe, and it is also the first time that Chinese enterprises have led the development and construction of nuclear power projects in western developed countries. It has been evaluated by the Chairman of the Supreme Leader as the flagship project to open the "golden age" between China and Britain, and will achieve a breakthrough in the export of China’s independent nuclear power technology to western developed countries.

　　Hualong No.1 also settled in Pakistan.

　　The K-2/K-3 nuclear power project in Karachi, Pakistan, undertaken by CNNC, is building two third-generation nuclear power technologies with independent intellectual property rights in China — — "Hualong No.1" reactor nuclear power unit. Quality is the life of a nuclear power plant. By the end of September, 2018, the quality control point of Jian ‘an construction witnessed a pass rate of 98%, far higher than the set target of 90%.

　　In terms of UHV and power grid construction

　　State Grid has actively promoted cross-border networking and interconnection, and built 10 cross-border transmission lines, including China, Russia, China, Mongolia and China-Kyrgyzstan, with a cumulative trading power of over 27 billion kWh. Vigorously invest and operate overseas infrastructure, and successfully invest and operate backbone energy grid companies in seven countries and regions, including the Philippines, Brazil, Portugal, Australia, Italy, Greece and Hong Kong, with an overseas investment of US$ 21 billion and total assets under management exceeding US$ 65.5 billion.

　　At present, the State Grid has completed major power grid projects such as the 800 kV HVDC transmission project of Brazil’s Meilishan Hydropower Station, the upgrade transmission project of Egypt’s EETC500 kV national backbone network, the 500 kV transmission and transformation project of Ethiopia’s GDHA, and the 500 kV DC interconnection project of Ethiopia and Kenya.

　　More importantly, we actively participated in the formulation of international standards, took the lead in establishing a complete technical standard system for UHV AC/DC and smart grid in the world, and took the lead in standards. In the future, more countries and people in the world will use the original UHV in China!

　　Oil and gas cooperation, increase the kinetic energy of economic growth

　　Oil and gas cooperation is an important part of the Belt and Road Initiative. Central enterprises’ oil and gas cooperation with foreign countries plays an important role in promoting the optimization of energy resources between countries and regions, providing sufficient power for China’s economy and promoting the common development of countries along the route.

　　China+Russian

　　Yamal Project is the first mega-energy cooperation project implemented in China after the "Belt and Road Initiative" was put forward, and China Petroleum participated in the joint development. This project is the largest LNG project in the Arctic region in the world at present, and it is known as "an energy pearl embedded in the Arctic Circle". On July 19th, 2018, the first ship of liquefied natural gas (LNG) supplied by Yamal LNG Project to China was delivered to Rudong LNG receiving station in Jiangsu under China Petroleum via the northeast Arctic waterway, and delivered to China Petroleum, which opened a new chapter for Yamal LNG Project to supply to China and brought a new gas source for clean energy supply in China.

　　China+Southeast Asia

　　The China-Myanmar crude oil pipeline was built with the participation of China Petroleum. The operation period of the project is 30 years, and the designed annual transportation capacity is 22 million tons. On April 10th, 2017, the China-Myanmar crude oil pipeline project was officially put into operation and entered China from Ruili, Yunnan.

　　China+Middle East

　　China Petrochemical Company is the largest oil refining company and the second largest chemical company in the world. In the Middle East, China Petrochemical and Saudi National Oil Company jointly established Yanbu China Petrochemical Ami Refinery Co., Ltd., which is a fuel refinery with a daily processing capacity of 400,000 barrels of Saudi heavy crude oil and China’s largest investment project in Saudi Arabia. On January 20th, 2016, the Supreme Leader of president, China and King Salman of Saudi Arabia attended the launching ceremony of the project. In 2018, the total amount of taxes (income tax, withholding tax, etc.) paid by the project to the Saudi government was nearly 57 million US dollars. At present, the joint venture company has more than 1,100 Saudi employees, accounting for 86% of the total number of employees, which is one of the enterprises with the highest proportion of Saudi employees in local enterprises.

　　China Petrochemical participated in the construction of a new refinery project in azur, Kuwait, which improved Kuwait’s refining capacity, reduced local environmental pressure, promoted local employment and promoted the development of local manufacturing industry in Kuwait. Upon completion, it will become the largest oil refinery in the Middle East.

　　The premise of economic development is sufficient energy supply. China enterprises give full play to their technological advantages, help countries along the Belt and Road to establish hydropower, thermal power and wind power projects, and empower the Belt and Road!

　　In Vietnam

　　The first phase BOT project of Yongxin coal-fired power plant built by China Southern Power Grid generates 1.358 billion kWh of electricity, and the annual power generation of about 8 billion kWh will effectively alleviate the power shortage in southern Vietnam.

　　In Laos

　　The Nantahe No.1 hydropower station project in China Southern Power Grid is expected to generate 721 million kWh of electricity, which will enable more than 2 million people to use green electricity. In addition to local power supply, the hydropower station can also provide electricity to the northern part of Thailand and the border areas between Myanmar and Laos, so as to realize the delivery of electricity from Laos.

　　In Pakistan

　　China was able to build the largest hydropower project of Pakistani Railway — — Nirum Jerum Hydropower Project, known as the "Three Gorges Project" of Pakistan Railway, can solve the power shortage problem of 15% of the population in Pakistan.

　　Two 660,000-kilowatt coal-fired power generation projects of Pakistan CLP Hubu, built by the State Power Investment Corporation and China Nengjian, can provide 9 billion kWh of electricity every year, meet the electricity demand of 4 million Pakistani families, and create nearly 10,000 jobs.

　　In Bangladesh

　　General Technology Group’s 365MW Gulashao combined cycle gas turbine power station project can meet the electricity demand of 180,000 households, greatly alleviating the power shortage in Dhaka, the capital of Bangladesh.

　　In Russia

　　The installed capacity of the Jeningskaya gas-steam combined cycle heating project in china huadian accounts for 31% of the effective installed capacity in Yaroslavl. Made up for the 68% power shortage in Yaroslavl.

　　In Argentina

　　China Power Construction is building a photovoltaic project at an altitude of 4019m, which will make "sun flowers" bloom on the Argentine plateau.

　　On the African continent

　　The Lower Kaifuxia Hydropower Project in Zambia built by China Power Company is the first large-scale hydropower project invested and developed by Zambia in 40 years, which can increase Zambia’s existing electricity by 38%. The Wangji coal-fired power station project in Zimbabwe will greatly alleviate the current situation of power shortage in Zimbabwe, effectively fill the gap between power supply and demand in Zimbabwe and improve local people’s livelihood.

　　in Europe

　　The Swedish North Pole wind power project acquired by CGNPC is the largest single onshore wind farm in Europe, which can meet the electricity demand of 400,000 households and reduce carbon dioxide emissions by 750,000 tons per year.

　　China’s hydropower, thermal power, wind power and photovoltaic are all over the world, making "China Infrastructure" a popular "source of power" for all countries.

　　Roads and Bridges: Promoting the Interconnection of Facilities

　　"Roads are accessible, and all industries are thriving", and the connectivity of transportation facilities is the basis for cooperative development. Transportation shoulders the heavy responsibility of "pioneering" and plays a leading role. Central enterprises focus on key passages, key cities and key projects, connect transportation networks, and push facilities interconnection to a new level.

　　China’s roads and bridges are mostly "first" and "records".

　　Moscow Metro in Russia — — China built the subway in Europe for the first time.

　　Russian enterprises entered the European market for the first time in this field, and led the entire industrial chain of Russian equipment, China technology, China design and China standard to break into Europe successfully, which was praised as "a new landmark of Sino-Russian friendship". China Railway Construction has created the fastest speed in Russia, which is "21 meters in 12 hours and 35 meters in a single day".

　　Ethiopia/Djibouti Yaji Railway — — China’s first "going out" railway with the whole industrial chain.

　　The Yaji Railway, with a total length of about 760 kilometers, is the first transnational electrified railway project in China that integrates "investment and financing, design, construction, main equipment and materials, supervision, locomotives and operation" with the whole industrial chain and the whole process of "China". After it was completed and opened to traffic, it has become the main channel for goods export and transportation in Ethiopia and even the hinterland of East Africa, greatly improving the transportation infrastructure status and logistics trade efficiency of Ethiopia and Djibouti, and radiating neighboring countries and inland areas of Africa, and being praised as "the new engine of African economic development" by African media.

　　Angola Benguela Railway — — China enterprises built the longest railway overseas at one time.

　　The railway runs across Angola, with a total length of 1,344 kilometers, which is equivalent to the distance from Beijing to Shanghai. It is the longest railway built overseas by China enterprises in this century. Benguela Railway will connect with Anzan Railway, Tanzan Railway and the railway networks of neighboring countries, realize the interconnection of railways in southern Africa, and form an international railway passage from the Atlantic Ocean to the Indian Ocean.

　　Turkey Anyi high-speed rail — — China’s first overseas high-speed rail.

　　The Anyi high-speed rail project is the first single high-speed rail project won by China enterprises in Europe. For the first time, China enterprises competed with their international counterparts on the same stage, successfully obtained the passport to enter the European high-speed rail construction market, and possessed the strength to participate in the international high-speed rail market competition.

　　Inner Mongolia Railway — — Kenya’s "flagship project"

　　Mombasa, Kenya, built by China Road and Bridge, which belongs to China Communications Construction — Nairobi Standard Gauge Railway (Munne Railway), with a total length of about 480 kilometers, is the initial section of the East African railway network and the "flagship project" for Kenya to realize its national development vision in 2030. The Inner Mongolia Railway not only used 56 diesel locomotives of three types of CRRC, but also established an operation system and trained technical personnel with the help of CRRC.

　　Peshawar-Lahore Expressway in Pakistan — — Batie north-south artery

　　This is the largest transportation infrastructure project of the "China-Pakistan Economic Corridor", and it is the economic artery and national defense artery connecting the north and south of Pakistan. The total length of the line is 392 kilometers, and there are five bridges over 200 meters. After completion, it will greatly improve the traffic conditions in the most economically developed and densely populated areas of Pakistan, effectively promote Pakistan’s economic and social development, and will also play a positive role in China-Pakistan interconnection.

　　Central Ma Youyi Bridge — — The first modern bridge in Maldives

　　The Ma Youyi-China Bridge in Maldives, which was built by China, is the first sea-crossing bridge in this country composed of more than 1,200 small coral islands. The total length is 2 kilometers, connecting Male Island and Airport Island. The main bridge is 760 meters long and its design service life is 100 years. It is located in the core economic circle of Male. The traffic between islands in Maldives depends entirely on ships and seaplanes, which makes it extremely inconvenient to travel. It has been the dream of the Maldivian people for many years to have a cross-sea bridge.

　　Maputo Bridge in Mozambique — — The longest suspension bridge in Africa

　　The Maputo Cross-sea Bridge in Mozambique, built by China Jiaojian, is the longest suspension bridge in Africa at present, with a total length of about 3 kilometers and a main span of 680 meters, which laid the foundation for the rapid development of southern Mozambique and even southern Africa as a whole, created 3,788 jobs for the local area and trained more than 5,000 skilled workers.

　　Central enterprises have built a large number of airports and ports along the "Belt and Road", making it so simple to "travel across oceans" and laying a good transportation foundation for international economic and trade cooperation and cultural exchanges.

　　Luanda new international airport in Angola built by aviation industry.

　　It will help Angola become an aviation hub in southwest Africa and a bridgehead connecting Africa with Asia, Europe and America.

　　Mozambique Saisai Airport aided by aviation industry

　　The annual passenger throughput is 220,000 passengers, which will not only benefit local people, but also improve the regional aviation infrastructure network and become a model for airport construction in Southeast Africa.

　　Colombo International Container Terminal, Sri Lanka

　　It is the overseas home port of China Merchants and has a key strategic position on the route from the Far East to Europe and the Maritime Silk Road. China Merchants invested in the wharf in 2009, with a coastline of 1,200 meters and an annual designed handling capacity of 2.4 million TEUs. At present, the annual profit of the terminal exceeds 50 million dollars.

　　Under the "One Belt, One Road" initiative, the overseas infrastructure forces of central enterprises have gone deep into cooperative countries and played an important role in the urban construction of the host countries. In the future, we will see a series of new urban landmarks built by central enterprises along the "Belt and Road".

　　We participated in the construction of the new capital of Egypt.

　　The new capital project of Egypt, in which China Architecture participates, is the number one key project currently being implemented by the Egyptian government. Upon completion, the new capital will become the new political center and financial center of Egypt. Among them, the highest point of the tower crown, the symbol of the central business district of Egypt’s new capital, is 385.8 meters, making it "the tallest building in Africa".

　　The main stadium in FIFA World Cup Qatar 2022 will also be "made in China".

　　In 2015, China Railway Construction successfully won the bid for the 2022 FIFA World Cup Qatar 2022 main stadium Lusel Stadium project. Lussel Stadium will be one of the venues where FIFA will hold the FIFA World Cup Qatar 2022 match in 2022, and it will be the main stadium for the opening ceremony, final and closing ceremony. The successful bid for the Lucerne Stadium project has further expanded the influence of China enterprises in the Middle East market and enhanced the international popularity of China brand. Who said that there was no China team in the World Cup?

　　Serving people’s livelihood: practicing the social responsibility of central enterprises

　　The connection between people’s hearts is the social foundation and public opinion guarantee of the "Belt and Road" construction, and improving people’s livelihood is the key to doing a good job of connecting people’s hearts. Based on social responsibility, central enterprises have implemented a lot of livelihood projects that can help the local people.

　　Food is the first necessity of the people.

　　In Ethiopia, SDIC has successively built three large modern sugar factories, namely Kense, OMO2 and OMO3, by adopting China standard, China technology and China equipment, which has greatly solved the problem of local sugar shortage.

　　The Shajiala Chemical Fertilizer Plant Project undertaken by Bangladesh was invested by SDIC.

　　It is the most advanced modern large-scale chemical fertilizer plant in Bangladesh, which has greatly promoted the development of industry and agriculture and the improvement of people’s livelihood in Bangladesh after the completion of the project. On October 14th, 2016, during his visit to Bangladesh, the Supreme Leader of president jointly unveiled the project with Prime Minister Hasina, and published a signed article entitled "Let China-Bangladesh Cooperation Harvest Golden Fruits", praising the outstanding contribution of the project to China-Bangladesh friendship.

　　Through its own efforts, China Railway has made 1.6 million people in the Lebanese capital drink tap water.

　　In Beirut, the capital of Lebanon, almost every household has several large water tanks on the roof, which residents use to store daily water. The water in the water tank is delivered to the door by a special water truck for a fee, but this kind of water is only used for daily washing, and drinking water needs extra money. The price of a box of water is as high as 25,000-50,000 Lebanese pounds (about 104-209 yuan). When there is a lot of water, you have to buy it every two to three days, and the monthly water consumption accounts for one-third of the income of ordinary residents.

　　To this end, China Railway independently designed and developed the world’s smallest diameter rock tunnel boring machine, and successfully completed the tunnel part of the great Beirut water diversion project of about 22 kilometers. Announced the official farewell of Beirut residents in Lebanon to bottled water.

　　Xiaoxin said

　　Over the past five years, the "One Belt, One Road" initiative has received positive responses from more and more countries and international organizations, attracted extensive attention from the international community, and its influence is expanding day by day.

　　In the practice of "One Belt, One Road" construction, central enterprises have effectively promoted the process of globalization through trade, factor flow and talent exchange, and have also become a new driving force for global economic recovery and global economic growth.

　　In the future, central enterprises will participate more deeply in the construction of the "Belt and Road", deepen the exchanges and cooperation between countries along the route in the fields of equipment, technology and management on the principle of mutual consultation, joint construction and sharing, strive to build a community of destiny and interests, and make greater contributions to promoting the sustainable development of the global economy!

Qiu Xiaofeng

Managing Director of CICC and Chief Analyst of Oil, Gas and Chemical Industry

Won the top two in the new wealth petrochemical industry for 12 consecutive years.

Using biological manufacturing technology instead of chemical processing will be an important way to reduce carbon emissions. How much carbon emissions can bio-manufacturing technology reduce? Which tracks are more advantageous among bio-based chemicals? What characteristics will enterprises stand out? Qiu Xiaofeng, managing director of CICC and chief analyst of oil, gas and chemical industry, explains it in detail for you.

The carbon emissions of bio-based products can be reduced by 60% to 70%, and the two major tracks have more advantages.

Qiu Xiaofeng said that products made from starch, sugar and other plants are bio-based products, and their carbon emissions can be reduced by 60% to 70% compared with petroleum-based products.

Among the many tracks of bio-based products, two tracks have more advantages: biodiesel and bio-aviation kerosene, and bio-based plastics.

Biodiesel is the best emission reduction scheme for commercial heavy trucks in the next decade, and hydrogen energy will be the final scheme.

Among bio-based products, biodiesel is the most important fuel in production and demand. In Qiu Xiaofeng’s view, at present, biodiesel technology has a high maturity and will be the best solution to reduce carbon emissions in public commercial vehicles such as heavy trucks in the next decade. Qiu Xiaofeng believes that in the longer term, with the maturity of water electrolysis hydrogen technology and the decline of photovoltaic power generation cost, the final solution will be hydrogen energy.

The market size of bio-based chemicals may reach 3 trillion yuan.

For the second category of bio-based products — — For bio-based chemicals, some analysts believe that almost all the chemicals known at present have corresponding bio-manufacturing routes, and large-scale amplification is expected. Qiu Xiaofeng said that bio-based chemicals have a wide range of applications, such as plastic bags, disposable lunch boxes, clothes, high-temperature resistant materials, etc. It is estimated that the overall market size of bio-based chemicals may reach 2 trillion to 3 trillion yuan by 2040.

Degradable plastics are expected to emerge in the "golden age"

Qiu Xiaofeng believes that in 2021, the degradable plastics industry will usher in a "golden age" in which hundreds of people compete, and PBAT and PLA polylactic acid will stand out. Due to the different technical points, the winning enterprises in their respective fields have the following characteristics:

PBAT: Controlling raw materials on a large scale and bringing them to market at a low price.

PLA polylactic acid: strong technical ability

Model: 2022 Geely Binyue Cool Engine

Car purchase time: 2022.9

Mileage: 2650

The vehicle has been used for a period of time, and it has both advantages and disadvantages. The advantages have been described in detail before, such as high face value, sufficient power, exquisite interior, rich configuration, etc. After use, some slots have naturally been found. Here, the shortcomings are mainly discussed for reference only.

1. When the appearance of the vehicle was dirty, I went to the 24-hour self-service car wash shop to wash the car manually. After washing it twice, I found that the tail of the whole vehicle was particularly easy to hide dirt and shelter people, especially the lime soil at the corner of the model was not easy to clean. In addition, the tail is also time-consuming and labor-intensive when cleaning the car. There is a gap between the bottom edge of the rear windshield and the car body, which makes it easier to store water and difficult to clean.

2. I feel that the whole vehicle is generally airtight. After washing the car, I open the door and there will be more water around the door frame.

3. The gray area below the central control screen area is not resistant to dirt. If there are black scratches or dirty things, it should be cleaned frequently.

4. The smoothness of the central control screen is average, which may be limited by cost considerations. At present, the built-in car machine system is not open enough, and there are few applications in the application market. Up to now, neither the system version nor the Gaode map version has been updated.

5. Some common driving-related functions, such as automatic parking, automatic start-stop and other common functions, have no physical buttons, and all need to be operated in the central control room, which is not very convenient, and it is impossible to control these functions with voice.

6. When the passengers in the car are talking, they will automatically trigger the voice of the car occasionally, which is annoying. If you use the car to navigate and play music at the same time, if the navigation sound is set too low, you can’t hear it clearly, and if it is loud, you always cut off the music sound.

7. How much can a glasses case cost? If it is low, it will be castrated.

8. Keyless entry function is only available in the main driver’s door, but not in the co-pilot. It is a little inconvenient to take things from the co-pilot.

9. Geely Mobile APP starts the vehicle remotely, and the air conditioner is started by default, and it must be turned off manually every time.

10. Driving mode defaults to intelligent mode, and I can’t change the default mode. I am used to comfortable mode.

11. I hollowed out the bottom of the central armrest and put the cigarette lighter there. I don’t think it makes much sense. I don’t know what can be put in that position. I usually use the adapter of cigarette lighter to charge my mobile phone, because the power can be higher, but because of the location, the charging cable can’t be fixed on it, and it always falls, so I have to bend down and pick up the charging cable every time.

The horizontal space at the 12-cup holder is slightly narrow, and the larger cups can’t be put down. The glove box space under the co-pilot is also slightly smaller.

13, the trunk space is really a little small, and the loading capacity is limited. Putting a trunk sorting box will take up 1/4 of the space.

After the mileage has passed 1000 kilometers, it is gradually found that the shift of gearbox in comfort mode is slightly delayed, and the intelligent mode will be much better, especially at low speed. When driving at a low speed in the first thousand kilometers, the speed will generally not exceed 1800 rpm, and the gear will be upshifted. The current situation is that when driving at a low speed, the speed will reach 2000-2300 rpm, and the upshift will become less active. This situation can be reduced if the oil is supplied at a constant speed.

15. After running several times at high speed, after the speed exceeds 160, the oil is accelerated, and the speed increase becomes slow. As the saying goes, it is boring, and it is still OK before 140.

16. The sound effect is not good, especially in the bass. The overall feeling of listening to music is not transparent enough, as if it were stuffy.

17. If the air conditioner is not used for a period of time, it will default to 22℃ when it is turned on again.

18. The car system is not smooth enough.

19. On the second day of driving, the 360 full shadow and reflection were not displayed when reversing, but it was better after driving for a while after the flameout. Occasionally I get stuck.

20. Some right rear door window lifters in the owner’s group have failed, which is an assembly process problem. Just plug them in again.

21. Some car owners reacted to the paint explosion on the roof.

22. Some car owners report that there are really too many minor illnesses in Binyue cool, such as the above problems.

The mainstream car has a moderate size and reasonable price, which is also a major feature of it, so it is loved and chosen by many families. Joint-venture vehicles have always been concerned, and today is one of them. Next, let’s see if its highlights can attract you with Xiaobian.

Let’s look at the appearance of sagitar first. The front face of sagitar gives people a very fashionable feeling. The air intake grille uses a trapezoidal shape, which is very sporty. Coupled with the headlights, the design is simple and fashionable. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, automatic steering, delayed closing, rain and fog mode and so on. Come to the car side, the car body size is 4791MM*1801MM*1465MM, the car uses exquisite lines, the car body looks very simple, with large-size thick-walled tires, eye-catching shape. Looking back, the overall shape of the rear of the car echoes the front of the car, and the taillights look very simple and fashionable. Overall, they are still quite domineering.

Sitting in the car, the interior looks very sporty and the whole looks very clean and refreshing. The car looks very good outside the steering wheel and is made of leather, giving a good grip experience. Let’s take a look at the central control, which is decorated with a 12-inch central control screen, which makes the interior design quite layered and very consistent with the temperament of the car. Let Xiaobian introduce the dashboard and seats. The dashboard design is remarkable and looks very delicate. The car adopts imitation leather seats, equipped with functions such as electric adjustment of auxiliary seats, electric adjustment of seats, and tilting of seats, which has good support and comfort.

Sagitar matched with dry dual clutch (DCT) gearbox has a maximum power of 118KW and a maximum torque of 250N.m, with good power performance.

The sagitar trunk has excellent overall performance and regular shape, which is convenient for people to take their luggage. At the same time, the car is equipped with fatigue warning, anti-lock braking (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), brake force distribution (EBD) main driver airbag, co-pilot airbag, knee airbag, side airbag curtain, front side airbag and other safety configurations.

The model class introduced today is the most considered class when many people buy their first car, mainly because the size of this class is moderate and the price is reasonable. If you like this car, don’t hurry to learn more about it!
