Changan Automobile used IoTDB to build a 150 million time series vehicle condition data processing scheme, and the query was stable to achieve millisecond return.

This article was interviewed from:Chang’anautomobile

1. Changan Automobile Business Scenario

Chongqing Changan Automobile Co., Ltd. is one of the four groups of China Automobile. It is an automobile company that develops, manufactures and sells a full range of passenger cars and commercial vehicles. Its main products include a full range of passenger cars, small commercial vehicles, light trucks, minivans and large and medium-sized buses, and a full range of engines. Changan Automobile always takes "leading automobile civilization and benefiting human life" as its mission, takes customers as its center and products as its main line, continuously provides high-quality products and services, and strives to promote the third venture-innovative business plan, transform itself into an intelligent low-carbon travel technology company, and strive to achieve world-renowned automobile enterprises.

At present, digital technology has deeply reconstructed the automobile. The automobile has gradually evolved from a mechanical product equipped with electronic functions to an electronic product equipped with mechanical functions. The integration of cloud data and AI technology has gradually turned the automobile into a large intelligent mobile terminal, data acquisition carrier, energy storage unit and a mobile multifunctional space. Generally speaking, the smart car has gradually transformed into a wheeled mobile robot with multi-functional space. In this context, the national policy strongly encourages the development of intelligent vehicles and self-driving driven by Industry-University-Research, and the domestic head and new power OEMs gradually take intelligent networked vehicles or self-driving direction as their core business.

Changan Automobile focuses on the development of intelligent vehicles, and its application panorama includes intelligent vehicle control (remote control analysis), intelligent cockpit (vehicle burial point, vehicle user behavior analysis),IoT Data access (access detection, vehicle activation monitoring) and IoT vehicle condition management (vehicle condition monitoring, power research, vehicle networking big screen), realizing business display including eye-catching system, vehicle remote diagnosis and remote early warning system, remote debugging system, etc.

In order to realize the construction of intelligent vehicles, Changan Automobile has built an intelligent vehicle data platform. This big data processing platform is divided into five layers: data access layer, data storage layer, resource scheduling layer, computing engine layer and business presentation layer. now IoTDB It is mainly used in the data storage layer to cope with the massive Internet of Vehicles.time series dataManagement.

The industrial scene of realizing intelligent automobile direction involves a large number of time series data acquisition of vehicle equipment and sensor layer, which is very important for time seriesData solutionThe perfection and efficiency of the system pose a great challenge. Changan Automobile’s current time series data solution has obvious limitations, so we hope to find a better solution for writing, storing, querying and analyzing the time series data in the field of intelligent automobiles.

Based on the characteristics and advantages of IoTDB time series database, Changan Automobile chose IoTDB as the time series data processing scheme of mass intelligent networked vehicles, which realized flexible expansion of mass data writing and storage, effectively improved query performance and reduced equipment and operation and maintenance costs.

2. Pain points of business requirements

210 million data measuring points, with over 10 million new data points per second.

Changan Automobile, as one of the four major automobile groups in China, has a huge business volume, and it needs to deal with a large number of vehicles and data. At present, Changan Automobile’s networked vehicle mass vehicle condition time series data management system has collected about 570,000 vehicles on the network, with a total of 150 million data measuring points and more than 10 million data points added every second. Therefore, Changan Automobile has high requirements for real-time writing, compression and storage of time series database under this data volume.

2.2 High-speed signal acquisition frequency is high

The vehicle acquisition signals of Changan Automobile can be divided into high-speed signals and conventional signals. High-speed signals need to be acquired in milliseconds, and conventional signals need to be acquired in 3-4 seconds. Changan Automobile’s time series data solution should be able to support these two different acquisition frequencies at the same time, and ensure the continuous operation of real-time low-delay acquisition of high-speed signals.

2.3 Low latency data query

The vehicle data query scenario of Changan Automobile mainly includes the effective query of multiple time series of bicycles and the query of the newest point of the full time series of bicycles, that is, the classic real-time and off-line vehicle condition/historical vehicle condition query scenario in the vehicle networking scenario. Changan Automobile’s time series data solution needs to effectively support real-time real-time query and query with a large amount of stored historical data with low delay.

Based on the previous time series data solution of Changan Automobile, a vehicle condition data entered HBase If you want to do analysis later, you need to completely unload the incremental data from HBase, and this batch of range reading process takes a long time. For example, if HBase wants to do offline processing of yesterday’s data, it needs to unload the operational data and put it into Hadoop for analysis this morning. In addition, with the increase of business volume, it takes longer and longer to use HBase for batch reading, which is not suitable for the rapidly expanding data volume scene.

2.4 High cost and maintenance difficulty

Changan Automobile initially adopted HBase as the solution of time series data management, but faced with tens of millions of data measuring points per second, HBase’s cluster data writing was undertaken by 25 data nodes, so many data nodes directly led to the high maintenance difficulty and cost of the system.

3. reasons for selecting IoTDB

3.1 The data structure ensures high scalability, low cost and high stability.

In view of the huge existing data volume and new data volume processing requirements of Changan Automobile, IoTDB’s exclusive native time series model of the Internet of Things stores time series data in layers of devices, measuring points/sensors. With the continuous increase of data volume, it only needs to directly expand the hardware equipment of the query node without interrupting the normal operation of the system, which can achieve second-level expansion and effectively reduce the management and operation costs.

3.2 to achieve tens of millions of writing speed

In view of Changan Automobile’s demand for frequent writing of time series data, IoTDB can write tens of millions of data points per second and handle multi-device billion-level data points, and the writing rate does not decrease with the increase of data volume, maintaining a stable high-speed level.

3.3 Support valid details and latest value query.

Changan Automobile will use IoTDB for detailed query of massive networked vehicle condition data in the scene of vehicle fault alarm. IoTDB adopts a storage architecture that combines the time stamps of data points from below the root node with multi-level storage paths, so that the time series data of different dimensions can be effectively classified and stored, and then the time series data in IoTDB can be determined quickly and uniquely during the query, so that the query efficiency can still be maintained under the condition of using detailed query.

3.4 Improve the batch reading rate and achieve real-time analysis.

In order to meet the demand of Changan Automobile for fast batch reading of data before data analysis, IoTDB can directly synchronize the underlying data files of IoTDB because of its time index, and use the seamless integration of IoTDB and other big data systems to directly analyze the stored file TsFile in real time with Spark engine, which reduces the number of exported copies required for data analysis and improves the analysis and calculation efficiency compared with the original scheme.

3.5 Timely operation and maintenance, and active verification

Changan Automobile Project believes that when the business scenario brings new challenges to the time series data solution, the efficiency and thinking of dealing with the problem is very important. The team behind an excellent time series data solution needs to be able to solve the problem quickly and make the database cover the performance improvement and rich functions required by the business scenario. When Changan Automobile encounters problems in the production environment, the R&D team of IoTDB will quickly coordinate with relevant R&D resources to help. As a team with more than ten years’ experience in researching and serving industrial users, the team members are particularly willing to use IoTDB to verify the ecological environment in the industrial Internet scene, so that the success of the project and the maturity of the product can achieve mutual benefit and win-win. Changan automobile project expressed its gratitude to the IoTDB development team.

It can be seen that the technical advantages of IoTDB can effectively solve the business pain point of Changan Automobile’s current management of time series data, so Changan Automobile chose IoTDB to build the data storage layer of Changan Smart Car Data Platform. This paper introduces and analyzes the solution architecture, time series model structure setting and query performance effect of large-scale time series data management built by Changan Automobile based on IoTDB.

4. Solution architecture

The Internet of Vehicles is a typical Internet of Things scenario. The main data of the Internet of Things scene is time series data, and the whole life cycle of time series data is divided into six stages: collection, caching, processing, storage, query analysis and visualization application.

In the scene of car networking in Chang ‘an, devices and sensors such as Tbox and THU are used to collect car networking data (such as EFI data of engines, rotational speed, vehicle speed, etc.). After the data goes to the cloud, the message is ingested based on the private TCP protocol of Changan Automobile and the gateway written based on Netty. After entering the TU-GW application of K8s through CLB, the message is parsed. The message is parsed and sent to the message queue, and the time sequence messages required by different services are distributed to different storage terminals. After being written into the storage engine, Changan Automobile TSP business system and APP will query the time series data according to the latest data and historical vehicle conditions.

At present, the architecture of large-scale time series data management of Changan Automobile is divided into 1.0 and 2.0 versions. In version 1.0, the time series storage engine mainly used for car condition scenes is HBase, which realizes the writing of historical car condition data. Due to the huge volume of historical data, 25 HBase data nodes need to write cluster data. At the same time, version 1.0 of HBase cluster is configured with 10 Region Server. Because the storage architecture of HBase cannot independently support the latest vehicle condition query, the latest vehicle condition query needs to be implemented based on Redis.

The architecture of version 2.0 adopts the architecture of writing data into IoTDB through Kafka. The test scenario adopts a single machine with high IO, that is, a cluster configuration with large memory (about 384 g) and full SSD (about 50 T). After the good data schema design of IoTDB, one IoTDB machine replaced the writing function of 25 HBase nodes, and successfully maintained high stability for more than one year. At present, the test data volume is about 1.5 million pieces of data per second, and one time series data involves 16-17 measuring points on average, which stably supports the overall writing data volume of about ten thousand levels.

At the same time, the powerful data query capability of IoTDB enables the version 2.0 based on IoTDB to realize a set of scenarios in which the engine supports the query of bicycle time range (real-time query) and the query of the newest point of bicycle full time series (latest vehicle condition query), and can stably achieve the millisecond return of the results of the two types of queries.

With the improvement of writing and querying ability, the time series data management architecture based on IoTDB greatly reduces the complexity of the original HBase+Redis scheme, and increases the volume of devices and data accessible to IoTDB. At present, Changan Automobile uses about 570,000 IoTDB stand-alone access devices, and the custody time series is about 150 million.

5. Time series model and query application

At present, in the design of the four-level node timing model of the root node, service name, equipment layer and sensor layer of IoTDB, the equipment layer of Changan Automobile adopts the TUID of TBOX, that is, the equipment ID as the third-level node; In the sensor/measuring point layer, except for the signal name, the CANID is connected with an underline as the fourth level node. The reason for the design of this storage structure is that it is convenient to use the select last * from root.CANID command supported by IoTDB to query all the data values of bicycles under a certain CANID, so that IoTDB can simultaneously realize the main query scenario of Changan Automobile: the combined query of real-time vehicle condition and historical vehicle condition.

With the support of this data structure, Changan Automobile uses the following statements to run common query scenarios:

1. Query the time range of a single device

The SQL statement is as follows:

Select canid _ signal from root. can _ condition. tuid where time > t1 and time6. Future prospect.

Since 2020, Changan Automobile and IoTDB have cooperated stably for 2 years, and a stable and effective intelligent networked vehicle remote monitoring system has been built. Because the intelligent networked automobile business is in the initial stage of explosion, it is foreseeable that the number and density of vehicles collected in the vehicle networking scene will greatly expand in the future, and the amount of time series data will also increase exponentially. Big source data is still the main problem that the vehicle networking system will face.

` In the future, Changan Automobile and IoTDB will work together to further expand the volume of vehicle data access, enrich the related applications and functions of IoTDB in vehicle networking scenarios, and realize effective management of more vehicle networking business time series data.

　　(Huang Sheng)

Be 100% good! ＂My Extraordinary Parents＂ Kara Wai was affirmed.

Special feature of 1905 film network　After 60 years old, I didn’t have a rest, but I was busier. My Extraordinary Parents and Look at a BridgeMe through the darknessI love you! "Save the suspect"… … One new play after another.

Among them, "My Extraordinary Parents" was first released, and Kara Wai played a blind mother in the film. In order to play the role well, she "experienced" it from the inside out.

After the film was released, many viewers praised Kara Wai’s good acting skills. The affirmation of the best actress in the three Hong Kong film awards has already proved Kara Wai’s strength. She has never slackened her efforts in every performance and always strives for perfection.In Kara Wai’s words, every role should be 100% dedicated, and every shot should be 100% good.

01.Play the blind, and make great efforts for both spirit and form.

My Extraordinary Parents, adapted from the director’s true story, tells the family story of a pair of blind parents raising their daughter with normal vision.

Kara Wai, who plays the blind mother, has made great efforts in shaping her appearance and manner.She keeps training to control her eyes, imitating the state that the eyes of the blind keep turning and their eyes are distracted. "I have practiced it, and I can go out and enter. Every time I shoot, I adjust my eyes to certain positions and spend a lot of hard work."

In addition to shaping the appearance, Kara Wai also asked an ophthalmologist to take a pair of copper contact lenses, put them on and carefully ponder the mentality of the blind. "It’s really the same as a blind person. When all the light is completely blocked, you lose your way, and then you can really play a blind person. What is her heart and what kind of dark fear she faces?"

Kara Wai said that every time she knows a role in advance, she will do all her homework well, and when she starts work, she will soon be able to enter the role.

In the movie, the emotional entanglement between mother and daughter also made Kara Wai feel the same way. Kara Wai has replaced many experiences and understanding of the relationship between her and her mother in the past. "When my daughter is rebellious, she can’t get along with her point of view, but they can’t be separated from each other and need each other, but this need sometimes hurts each other. This is the way I used when I played with Qianyu."

"I have to be 100% good in every shot until now." Kara Wai said that the principle of her acting is that if she gets paid, she must do it well, and at the same time, she must respect the actor’s profession. "Every shot should stay forever. If I don’t shoot a shot well, I will miss it for a long time."

02."I’m so strong, I’m afraid Jiang Lang will run out of talent."

Kara Wai, who was born as an action actor, got up from the bottom and struggled all the way to this day in fighting with blood and injuries again and again, and achieved many achievements.

Kara Wai had a hard childhood. At the age of three or four, he peddled with his family in the streets of Wan Chai. As a teenager, he worked as a dancer in a nightclub. Later, he was dug up by the director and made the film Legend of the Condor Heroes as Mu Nianci. Since then, he has entered the film industry and changed his life.

Kara Wai has the personality of a wild child since she was a child, and she has the experience of dancing on the stage, so she was not timid when she made a movie for the first time.

The first scene of The Legend of the Condor Heroes was a contest to get married, and Kara Wai was taught to play opera directly on the spot. The confidence and elan of the newborn calf that was not afraid of tigers made the hero alexander fu mistakenly think that she had been filming for several years.

The movie dream was planted when Kara Wai was young. Like many children at that time, she often sneaked into the cinema to watch movies. The first movie she saw was yes, and her awe of movies and performances was born from then on.

Mu Nianci became famous in World War I, and Kara Wai successfully entered Shaw Pictures as a martial arts actor and studied under the direction. At the age of 22, she won the Best Actress Award in the first Hong Kong Film Awards. In her view, the first Golden Awards trophy was won entirely by fighting and relying on life and health.

"You ask me how many injuries, I don’t know. You ask me where I am not injured, and I can tell you that I am not. " When Shaw made a martial arts film, Kara Wai was viciously punched in the stomach by an opposite actor for more than 40 times. At that time, she had only one thought: "If you didn’t kill me, I would have a chance in the future. I want to cover you up in this scene today. "

Therefore, when Kara Wai won the prize for the first time, all she thought about was bitterness. "I play every day and get hurt every day. Even if I have surgery, the thread has not been removed a few days later, and I still have to shoot with my stomach covered." Even if she became more and more popular later, she would feel a little unbalanced when she saw other actors shooting fashion shows, beautiful and comfortable.

But Kara Wai is an indomitable person by nature. "When you are chosen for the role of martial arts and you need it again, you can only do it best. I must stand in the first place to survive. "

Kara Wai’s perseverance, also have been crushed. At the end of 1990s, with the decline of martial arts films and the change of movie environment from generation to generation, Kara Wai’s career fell into a trough, and she suffered from depression. In the worst case, she even swallowed sleeping pills and gave up herself. Fortunately, with the help of relatives and friends, she rallied.

In 2010, 50-year-old Kara Wai won the Best Actress Award at the Hong Kong Film Awards for the second time for "Devil". I have experienced all kinds of twists and turns from being a popular female star to being neglected and making a comeback. The arrival of this award is of great significance to her and has the deepest feelings.

Kara Wai recalled, "I hold this award, and I said that nothing can be changed, because it was because I suffered a lot of grievances, paid a lot of efforts, and had a chance given to me by many friends and God, so this award is more important than anything."

Later, Kara Wai won the Golden Award for Best Actress for the third time. She plays an elderly person who lives alone with Alzheimer’s disease. Kara Wai’s mother died because of this disease. She wants to use this film to commemorate her mother and make more people pay attention to Alzheimer’s disease.

Kara Wai cares about the disadvantaged groups, and this time he took on My Extraordinary Parents, hoping to use this positive film to appeal to the public to respect and care for the visually impaired.

Kara Wai doesn’t act in action movies now, and she will also worry about her bad state and poor performance when acting in literary plays. "The more I am so strong, the less I can perform, the less I let others know, the more I force myself, and I really can’t perform. The director is sorry to give me two minutes, and I will walk away again. The whole mood will be adjusted. It is psychological pressure to throw away all the feeling of smoking and come back."

Nowadays, Kara Wai likes to cooperate with new directors, trying her best to support young talents, and even working with them at a reduced salary. This is the case with My Extraordinary Parents, and the sincerity of the director made her determined to take over.

Every time acting, Kara Wai wants to find a new way to perform. "How can I act when I have met several bottlenecks?"? I can’t find it. I can only play it in the old way, so I can’t open it. The new directors have new ideas, and they can bring me many new things and new ways of interpretation. "

"I am afraid that people will see that I am exhausted in Jiang Lang." Kara Wai didn’t stop, she was still fighting and rushing.

Another wave of end-of-year coupons came to the local area, focusing on these consumption areas in the fourth quarter.

　　Near the end of the year, another batch of coupons began to be distributed intensively.

　　Recently, Sichuan, Jiangxi, Beijing, Sanya, Wuhan and other provinces and cities have successively issued coupons for cultural tourism or automobile appliances, and some provinces and cities have also announced that they will issue coupons in the near future. Not only that, these places have also introduced various policies and measures to boost and expand consumption.

　　Intensive distribution of consumer vouchers

　　On November 27th, Sanya issued the third tax-free coupons for tourists from all over the country, with a maximum reduction of 1,600 yuan. Previously, the Sanya Municipal Bureau of Commerce issued "Several Measures to Further Promote Consumption Growth in Sanya in 2023", demanding that tax-free promotion be vigorously carried out, tax-free coupons be issued, and tax-free business entities be encouraged and guided to hold tax-free promotion activities.

　　In recent days, Sichuan, Guangdong, Jiangxi, Wuhan, Beijing and other provinces and cities have also intensively issued coupons or announced that they will issue coupons in the near future. These coupons are basically based on cultural tourism consumption and automobile household appliances consumption.

　　For example, Guangdong will issue 100 million yuan coupons for cultural tours to residents and tourists who spend money in Guangdong, provide 1 million discount tickets for scenic spots, distribute 1 million special discount air tickets and launch 10,000 discount rooms.

　　On December 1st, Jiangxi will begin to issue the "2023 Jiangxi Provincial Automobile Voucher" with a total amount of 19.53 million yuan to the whole province. There are 6,510 car coupons for this activity, and the amount of each car coupon is set to 3,000 yuan regardless of the car purchase price.

　　The 2023 "Shu Li An Yi, Warm Winter and Enjoy" coupons issued by Sichuan Province are mainly aimed at supermarkets, home appliances, restaurants and other key areas of consumption. Among them, the provincial finance contributed 100 million yuan, the supporting funds of each issuing platform are expected to exceed 300 million yuan, the merchants discounted and promoted 100 million yuan, and the expected profit-making amount exceeded 500 million yuan.

　　Zeng Junlin, deputy director of the Sichuan Provincial Bureau of Statistics, said that the consumer market in Sichuan performed well in the first three quarters, but there was still a gap from normal growth. The total retail sales of social consumer goods only increased by 4.4% on average in two years, which was 5.9 percentage points lower than the same period in 2019. Traditional retail sales are under pressure, the retail sales of convenience stores only increased by 1.5%, and the retail sales of supermarkets decreased by 0.1%.

　　Chang Yang, chief analyst of Zhongtai Securities Research Institute, told CBN that from the CPI data of 31 provinces recently released by the National Bureau of Statistics, we can observe the differentiation among different provinces. Judging from the data of chain growth rate, 17 of the 31 provinces saw a decline in chain growth rate in October, reflecting that demand in most provinces was weak compared with supply in the short term.

　　With the continuous efforts of this year’s consumption promotion policy and the National Day Golden Week, the consumption data in October this year showed an accelerated recovery. In October, the total retail sales of consumer goods nationwide reached 4,333.3 billion yuan, up 7.6% year-on-year, and the growth rate was 2.1 percentage points faster than that in September. After deducting the price factor, the total retail sales of social consumer goods actually increased by 8.4%, 2.3 percentage points faster than that in September.

　　However, Fu Jiaqi, a statistician of the Department of Trade and Economics of the National Bureau of Statistics, interpreted the data of the consumer market in October and thought that although the consumer market maintained a good recovery momentum, we should also see that the acceleration of the growth rate of total retail sales of social consumer goods in October was due to the low base in the same period of last year. At present, the consumption power and willingness of residents still need to be improved, the recovery of residential goods is lagging behind, and the operating pressure of some commercial enterprises is still relatively high.

　　Sprint in the fourth quarter to achieve the annual goal

　　In fact, in comparison, the recovery of consumption, especially contact consumption, is more obvious and has become the main driving force for economic growth. Especially from November to December last year, under the serious influence of the epidemic, consumption declined, so there was a low cardinal utility. Stimulating consumption in the last two months of this year will be of great help to promote economic growth and accomplish this year’s goals and tasks.

　　The data shows that in November 2022, the total retail sales of social consumer goods was 3,861.5 billion yuan, down 5.9% year-on-year. Among them, the retail sales of consumer goods other than automobiles reached 3,482.8 billion yuan, down 6.1%. In December 2022, the total retail sales of social consumer goods was 4,054.2 billion yuan, down 1.8% year-on-year. Among them, the retail sales of consumer goods other than automobiles reached 3,543.8 billion yuan, down 2.6%.

　　On October 27th, Sichuan Province held a teleconference on the province’s economic operation scheduling in the fourth quarter of 2023. In response to the sprint in the last two months of this year, the meeting requested that in terms of scheduling strategy, precise policies should be made by industry, agriculture should make up the gap as much as possible and tie the country, industry should overcome difficulties and consolidate the momentum of recovery, and service industry should carry a heavier burden and gallop.

　　Since the beginning of this year, due to the influence of multiple factors, the downward pressure on some local economies has continued to increase. Therefore, it is necessary to make up for the shortcomings and make the consumption and service industries "pick a heavier list" and "Dora Run" become a breakthrough for local shocks in the fourth quarter.

　　On November 24th, the website of Guangdong Provincial Government published "Several Measures to Further Boost and Expand Consumption in Guangdong Province", which put forward 27 specific measures from eight aspects, including stabilizing automobile consumption, promoting household appliances and electronic products consumption, stabilizing housing consumption, and promoting the expansion and upgrading of service consumption.

　　Before the meeting in Sichuan Province mentioned above, in order to further take effective measures to stimulate market vitality, sprint this year’s objectives and tasks, promote a good start next year, and promote the sustained improvement of economic operation, the General Office of the Sichuan Provincial Government issued a number of policies and measures on further stimulating market vitality and promoting the sustained improvement of current economic operation.

　　Among them, the boosting policy includes not only issuing consumer vouchers, but also implementing measures such as financial discount on consumer credit, with real money to support it. During the period from September 1, 2023 to March 31, 2024, the banking institutions issued one-year and above off-line consumer loans to residents in the province, which were used for four categories of goods, such as automobile purchase, electronic products, housing decoration, household appliances, furniture and durable goods. The financial department gave the residents a one-year one-time discount at an annualized interest rate of 1.5% with a single amount not exceeding 3,000 yuan.

　　In addition, Sichuan has also implemented measures such as subsidies for new flight routes in winter, incentives for travel agencies to attract customers into Sichuan, and reduction of tolls for small passenger cars from outside Sichuan. During the "Winter Tour in Sichuan Consumption Season", travel agencies that organize tourism teams to come to Sichuan will be rewarded according to each person’s trip to 30 yuan; In addition to the existing ETC preferential policies, a 50% discount will be given to the tolls of small passenger cars (Class I passenger cars) with license plates outside the province.

The class teacher drew a super cute pinyin table, but half the students in the class had finished learning pinyin in advance.

　　The summer vacation is about to return to zero. These days, not only students who have not finished their homework, but also novice teachers who are about to take over the first batch of students in their lives are in a state of intense preparation. For the new semester that will start soon, their hearts are both looking forward to and uneasy.

　　Jiang Li, a teacher at Dinglan No.2 Primary School in Hangzhou, went to Qianbao reporter to tell her recent distress. Because Mr. Ding found that the "opening gift" that he started preparing for freshmen early may not be used.

　　It is a difficult problem for freshmen to learn pinyin.

　　She racked her brains to think of a way.

　　Teacher Jiang is a post-1995, who just joined this year. After the new semester begins, she will be the Chinese teacher and head teacher of Class 1 (5) in the school.

　　Because he is a novice, this summer vacation, Mr. Jiang has almost no rest and has been preparing for the new semester. Nowadays, all primary schools advocate zero-based admission, regardless of pinyin or literacy, they begin to learn after entering primary school. Therefore, when preparing lessons, Mr. Jiang thought a lot of countermeasures for the problems that zero-based students often encounter when they are beginners.

　　"For children in grade one, pinyin is very difficult to learn. Because letters are too abstract for them, it is difficult to establish a connection between letters and pronunciations, and many letters with similar shapes and sounds are easily confused. " Teacher Jiang said.

　　This summer vacation, she has been thinking about pinyin. How can we help children learn pinyin effectively?

　　Not long ago, when practicing the standard writing of pinyin, Teacher Jiang had an epiphany and came up with a way — — Hand-drawn cartoon pinyin table.

　　"In math textbooks, in order to let children remember the writing of numbers, each number will be integrated into cartoon pictures. Pinyin and numbers are abstract symbols. If pinyin letters are also integrated into cartoon patterns, they may have the same effect. " Teacher Jiang explained.

　　After having an idea, she immediately started to work and spent an hour to finish the preliminary drawing of the cartoon pinyin table. On this pinyin table, some common animals or articles are painted, and one or two pinyin letters are "inlaid" in each pattern. "Now this is just a sketch. I’m going to ask the art teacher for help to further beautify and simplify the pattern, and then use it as a teaching tool for students to consolidate their knowledge and expand their thinking." Teacher Jiang said that she also considered letting students draw together, and the "mosaic" way of patterns and letters was designed by the students themselves.

　　I have to say that this is a very creative idea. Adding vivid teaching methods such as pictures, jingles and finger dancing to the classroom can help junior children enjoy the class more quickly and develop their imagination.

　　However, Mr. Jiang soon found that his "opening ceremony" carefully prepared for the students was probably not used.

　　More than half the students in the class.

　　I finished learning pinyin in advance.

　　"I know that some students will definitely learn Pinyin in advance during the summer vacation, but the proportion should not be too large, and even if they want to learn, they will not learn it systematically." Teacher Jiang said.

　　These two days, she made a home visit to the students in her class, and this idea was completely subverted. "I found that more than half of the students in the class have almost finished learning Pinyin in advance." During her home visit, she specially brought her textbooks to check on the spot. Many students who have studied pinyin have mastered the most difficult polysyllabic pinyin and can basically spell it freely.

　　"I can understand the anxiety of parents who are afraid that their children can’t keep up with the start of school, but every teacher will prepare lessons according to the progress of the class before class. Such advanced learning will disrupt the teacher’s teaching plan." Teacher Jiang said helplessly. In her opinion, such advanced learning is not necessarily good for children.

　　"In class, I will abide by the barrel principle and take students who have not mastered pinyin as the standard. I will not give up those who have not learned because most people have learned it." Teacher Jiang said. Moreover, during her home visit, she found that many students’ pronunciation was not standard when they were receiving off-campus training because the teacher didn’t teach them seriously. After all, Pinyin is the most basic thing in Chinese learning. If there are mistakes at the beginning, it will be more difficult to correct them later, which will also have a negative impact on children’s future study.

　　After discovering this problem, Mr. Jiang was busy again, and the lesson plans that had been prepared for more than half a month needed to be readjusted.

　　"In the past, preparing lessons was based on zero-based children. Now we need to redesign the way of class according to the differences in students’ learning level." Teacher Jiang said. In the future teaching, she will pay more attention to students with zero starting point and cultivate their interest in learning as soon as possible. For those children who have learned pinyin, she will pay attention to their learning methods and spelling methods, and get rid of some incorrect places, so that they can apply pinyin to Chinese learning as soon as possible.

　　"You can also let the children who have learned Pinyin study with other children to form a good learning atmosphere." Teacher Jiang said. (Reporter Jianwei Liang correspondent Chen Hongcheng)

Tengshi N9 declaration information exposure vehicle length is over 5m 2 and wheelbase is over 3m 1.

After the flagship of MPV and sedan, the flagship of brand SUV is coming. After many spy photos were exposed, Tengshi N9 boarded the latest new car declaration catalogue of the Ministry of Industry and Information Technology.

As can be seen from the declaration, the overall design of Tengshi N9 is still very imposing, and the closed front face is not monotonous. There are C-shaped decorations on both sides of the front of the car, and a trapezoidal air inlet with a small area is left at the bottom of the front bumper. The side lines of the car body are relatively straight, but there is a curve that fits the wheel arch before and after, which makes the huge car body more harmonious. The rear part of the car is designed to be relatively full, and the taillights and high-position brake lights are designed in long strips, but they are not connected through.

Of course, there are different opinions about the appearance of Tengshi N9, but as a flagship model, it is not a bad thing to be more mature and stable. Moreover, the electronic exterior rearview mirror and the lidar on the roof highlight the scientific and technological attributes.

In addition, the detailed body dimensions are provided in the application information. The length, width and height of Tengshi N9 are 5258mm/2030mm/1830mm respectively, and the wheelbase reaches 3125mm, which is at the same level as that of Hehe.

In terms of power, Tengshi N9 will be equipped with a hybrid system consisting of 2.0T engine and 3 motors, in which the maximum power of the engine is 152kW, the maximum power of the front motor is 200kW, and the maximum power of the two rear motors is 240kW respectively. Therefore, although Tengshi N9 has a huge body, its dynamic performance is also very strong, and its maximum speed can reach 230 km/h. In addition, Tengshi N9 will be equipped with a group of 46.992kWh, with a pure battery life of 165km.

Zhao Changjiang, general manager of Tengshi Sales Division, once said on social media that Tengshi N9 will be an SUV that peers can’t catch up with in five years. Therefore, in addition to the oversized body size and easy three-way technology, Tengshi N9 may have more functions and configurations worth looking forward to.

In the past year, under the leadership of Chairman of the Supreme Leader, China has made all-round progress in economy, politics, culture, society and ecological civilization, and its development achievements are remarkable. The "Belt and Road" construction has achieved fruitful results, and countries along the route have benefited a lot, and China’s international status has been continuously improved. Overseas Chinese feel the same way about every progress made in China, and sincerely hope that China will continue to make new and greater achievements.

Under the correct leadership of the Supreme Leader, China is developing with each passing day. Overseas Chinese are full of confidence in the future of their ancestral home country, and sincerely hope that the road of China’s development will be wider and wider!

　　The "One Belt, One Road" initiative put forward by the Chairman of the Supreme Leader is conducive to promoting the common development of Southeast Asian countries and jointly building a community of human destiny. The rise of China has shown the image of a great country to the whole world and provided a rare opportunity for the development of neighboring countries. Since the second half of last year, the relationship between the Philippines and China has achieved a "gorgeous turn" and the cooperation between the two countries has become increasingly close. I hope that the Philippines can take the "Belt and Road" development express train in time and become an important partner along the route to realize its rapid development.

I have worked hard in Egypt for many years, and I have personally felt the increasing pragmatic cooperation between China and Egypt in various fields, and I have also felt that China is becoming stronger and richer. On the occasion of the arrival of the Spring Festival, I wish the people of the whole country a happy New Year, and wish China prosperity and new achievements in the great journey of building a well-off society in an all-round way.

As President Xi said, we will roll up our sleeves and make more contributions to building a well-off society in an all-round way in the new year. Overseas Chinese in South Africa will continue to safeguard the overall situation of China-South Africa friendship and cooperation. In 2016, the global economy is sluggish, and the locomotive role of China’s economy is becoming more and more obvious, which is true for the South African economy and more important for overseas Chinese in South Africa.

The development of the motherland has given us great confidence and enthusiasm. More and more Russian friends let their children and grandchildren learn Chinese, shop on Taobao and travel to China.

　　This year, I helped the Russian Ministry of Education and Science to organize summer camps for young people of the two countries. The exchanges between young people of the two countries ignited the desire of the younger generation in Russia to learn more about China and planted seeds for the deepening of friendship between the two countries. I hope to continue to contribute to the development of bilateral relations in the new year. I wish the people of the motherland a happy New Year, the country is prosperous and the people are happy and healthy!

　　Chairman Supreme Leader met with overseas Chinese representatives during his state visit to Germany in 2014, and I had the honor to attend. In his speech, President Xi encouraged overseas Chinese living in Germany to cherish their motherland and integrate into the local area. For more than two years, we have consciously paid more attention to the two-way nature of public diplomacy in our activities, and listened to others’ voices while making our own "voices".

　　This year marks the 45th anniversary of the establishment of diplomatic relations between China and Germany. China will usher in the 19th National Congress of the Communist Party of China, and Germany will host the G20 Summit, and a series of high-level visits will be conducted between the two countries.

　　The most exciting moment for me in 2016 is to welcome the Chairman of the Supreme Leader to visit Serbia. President Xi is affable and earnest, which adds strength to us overseas Chinese who start businesses in foreign countries. The Belt and Road Initiative proposed by President Xi has paved the way for boosting the world economy. Many countries in Europe and Asia have actively responded to the "Belt and Road Initiative" and set off a new round of "China fever" from the official to the private sector, and the friendly and cooperative relations with China have rapidly warmed up.

　　As a post-1970s generation, I witnessed the great changes in China from weak to strong and from poor to rich after the reform and opening up. As an old overseas Chinese who has been wandering overseas for more than 20 years, I personally feel the great glory that China’s prosperity has brought to overseas travelers. On the occasion of the Spring Festival, I sincerely wish China prosperity and the people of all ethnic groups in China happiness and well-being!
