　　In the early morning of July 28th, Zheng Jichun set out with a small boat. His destination is the collection point of living materials in the town. Since 82 affected people in the village came to the resettlement site, as the principal of Gaolin Primary School in Sanbing Town, Chaohu City, Anhui Province, Zheng Jichun, an old party member, volunteered to take charge of everyone’s daily life. "The public sentiment is urgent. I have not been able to fight floods in the front line like other party member, but I hope to do my best to help the affected people eat and drink at the temporary resettlement sites." Zheng Jichun said.

　　Since the flood season, there has been continuous heavy rainfall in Hefei, and all the main rivers in Chaohu Lake basin have exceeded the police. At the same time, they are under great pressure from the flood control of the Yangtze River and Chaohu Lake and the urban flood control. In the face of severe flood, Party organizations at all levels in the city and many party member bravely took the lead and rushed to the key positions of flood control, building dams for flood control and flood fighting, guarding their homes and the safety of people’s lives and property.

　　Keep safe and branch to the front line.

　　21 temporary party branches are on duty 24 hours a day, guarding major rivers, Chaohu dams and key areas.

　　The water level in Chaohu Lake has exceeded the once-in-a-century standard for many days.

　　There are three rivers entering the lake and 10.8km Chaohu levee outside. Yicheng Street in Baohe District of Hefei City is in the front line of flood control. In order to carry out flood control and emergency rescue work in a timely and effective manner, the Party Working Committee of Yicheng Street set up a temporary party branch immediately after receiving the flood warning, and moved 17 party branches of government agencies, residential villages and urban management to the levee.

　　The temporary party branches are in charge of each section, with the branch secretary taking the lead and party member participating in it. The surrounding people saw it and took the initiative to join it. In a short time, more than 300 volunteers gathered, including more than 200 party member.

　　"The water level is rising!" When patrolling the embankment, Yang Guoqing observed that the water level in Lirong section of the road around the lake was rising, and the embankment nearly 10 meters long in front was low in terrain, which was in danger of overflowing at any time. As the leader of a flood control emergency group, Yang Guoqing made a decisive decision and quickly organized to reinforce the dam. Shovel silt, tie bags, pass sandbags and build dams. Yang Guoqing and more than 10 party member fought together for nearly 2 hours, raising the dam by 1.2 meters.

　　On the flood control dam, besides party member volunteers, there are fishermen "soil experts". Shu Congming, 68, is a native of Chaohu Lake and an old party member. He took the lead in setting up an "old fisherman’s dam guard team". The team members not only patrol the dam during the flood season, but also clean up the weeds and garbage along the lake and river on weekdays. Now, under the leadership of Shu Congming, this "old fisherman’s dam guard team" is divided into two roads, patrolling the embankment once an hour and being on duty 24 hours a day.

　　"In front of the flood, a grassroots party organization is a fighting fortress." Ge Rui, secretary of the Baohe District Party Committee of Hefei City, said that building a temporary party organization in the front line of flood control and disaster relief can transform the party’s political advantages, organizational advantages and close ties with the masses into a powerful synergy for flood control and disaster relief. Today, Baohe District has set up 32 flood control emergency duty points and 21 temporary party branches in major rivers and Chaohu dams and key sections, and implemented 24-hour lighting duty.

　　Patrol the dam, party member rushed ahead.

　　At present, more than 50,000 party member cadres have devoted themselves to flood control and emergency rescue.

　　At 6 o’clock in the morning, at first light, Li Yebing got on the electric motorcycle and rushed to the dam. When he reached the Nanfei River, he put on his raincoat, rubber shoes and shovel, and began to patrol the embankment. Party member, a 72-year-old man from Shikou Community, Changlinhe Town, Feidong County, Hefei City, has been involved in flood control since late June. "I am old, but I have much experience! It is glorious that I can still play a little residual heat before the flood. " Li Yebing introduced with a smile that there are eight people involved in his community, each of whom is responsible for inspecting the dam about 1.5 kilometers. "At first, it was a six-hour patrol, and later it became three hours. Now, it is necessary to patrol the embankment every hour."

　　It’s still raining, and the water level of Nanfeihe River is rising almost every day. Li Yebing patrolled the embankment and dared not slack off. At noon, I got a box lunch and sat on a pony. While eating, Li Yebing still kept an eye on the water. "Once it is found that the water level exceeds the safety limit or leaks, it must be rushed up at the first time. This is my responsibility as an old party member! Don’t say that I am only 72 years old. Even if I am 82 or 92 years old, I will still stick to the front line of flood control. " Li Yebing said.

　　"The flood fighting and emergency rescue is a big test for party member. They move at the command and smell ‘ Flood season ’ Attacking, regardless of gains and losses, fighting selflessly, fully embodies the responsibility and responsibility of Communist party member. " Yao Fei, county magistrate of Feidong County, said.

　　It is understood that at present, more than 50,000 party member cadres have been involved in flood control emergency rescue in Hefei, and more than 380 party member commandos, more than 260 party member rescue teams and more than 650 party member volunteer service teams have been established.

　　Anti-waterlogging, no dead angle in investigation

　　Knocking on the door from door to door, earnestly persuading them to leave, working for dozens of hours, and moving the pump truck to help drain nearly 420,000 cubic meters of water.

　　Not long ago, heavy rain poured down in Hefei. "No, there is water at the intersection of North First Ring Road and Feixi Road!" In Hefei Urban and Rural Flood Control Headquarters, he hung up the phone, and Chen Shiyong immediately called up the flood control command and dispatch system to check information, judge water level and dispatch drainage vehicles. Then, he plunged into the rain and started to rush to the scene.

　　Chen Shiyong, 45, is the district leader of the Drainage Management Office of Hefei Urban and Rural Construction Bureau. He has been a party member for 25 years. During the flood season, he is responsible for the inspection and maintenance of drainage facilities within his jurisdiction and the emergency response to flood control. The water at the intersection has exceeded the warning water level. The transferred large mobile pump truck is racing against time to pump water and discharge it. Arrange personnel to inspect the wellhead and outlet as quickly as possible.

　　The merchants along the street are about to be flooded, and there is no time to think about it. Chen Shiyong knocks on the door from door to door, earnestly persuading him to leave. The water level of Banqiao River was too high, and the water accumulated on the road surface for a long time was caused by backward flow. He took the lead in launching water for investigation and went down to block the drainage outlet. "The drainage facilities in the city are our key focus. Once a fault occurs, it is likely to cause urban waterlogging." Chen Shiyong said, "In the past, we ensured traffic. Now, we have to ensure safety."

　　Chen Shiyong led the team members to work continuously for dozens of hours, during which mobile pump trucks were dispatched to help drain more than 30 times, helping to drain nearly 420,000 cubic meters of water. It’s still raining, but the accumulated water has gradually receded.

　　In order to prevent urban waterlogging and flood season, Hefei Urban and Rural Flood Control Headquarters strictly implemented the 24-hour duty system and the leadership shift system in flood season. On the one hand, strengthen the inspectors who are on duty under the bridge and at the flood-prone points to ensure that the personnel are on the job and carry out emergency response at the first time; On the other hand, ensure that "the accumulated water is as little as possible and the accumulated water time is as short as possible".

　　China news agency, Washington, February 17 th: The giant panda "Baby" in the United States is about to return to China, and the American people are reluctant to send their blessings.

　　China News Service reporter Diao Haiyang

　　In less than four days, the giant panda "Bao Bao" in the United States will soon embark on a trip back to China. In the past few days, many Americans have gone to the National Zoo in Washington to bid farewell to their beloved "baby" and send their best wishes.

　　Baby, a female giant panda, was born at the National Zoo in Washington on August 23rd, 2013. Her parents are Tian Tian and Mei Xiang, giant pandas living in the United States. Rui Thompson, a biologist and deputy director of the Panda Pavilion at the Washington National Zoo, said that Mei Xiang didn’t give birth to a second cub until 2012 after giving birth to the male giant panda "Taishan" in 2005, but it only survived for a week. Therefore, the birth of a "baby" is simply a miracle.

　　"Baby" has attracted the attention of the United States since its birth. Its first public appearance made the whole Washington National Zoo very lively, and some fans drove for 9 hours just to see its budding state.

　　On February 16, local time, many Americans came to the National Zoo in Washington to bid farewell to the giant panda "Baby" in the United States. "Baby" will leave for home on the 21st of this month. China News Service reporter Yan Haiyang photo

　　The name "Baby" comes from an online voting activity jointly sponsored by the Washington National Zoo, the China Embassy in the United States and the US Embassy in China. On its centenary, the wives of the heads of state of China and the United States each sent blessings to it through a video. When it was one year old, the zoo also held a special "grab the week" ceremony.

　　In a blink of an eye, "Baby" has grown from a cute pink cub to a giant panda weighing 188 pounds (about 85 kilograms). According to the agreement between China and the United States, the "baby" needs to return to China before he is 4 years old.

　　The Washington National Zoo announced on the 6th of this month that Baby will leave for China on the 21st of this month, and the zoo will hold a six-day "Farewell to Baby" special event from the 16th.

　　On the first day of the event, a large number of fans and media reporters went to the panda hall of the zoo to bid farewell to the "baby". People raised their mobile phones and cameras to record its last week in Washington.

　　On February 16, local time, many Americans came to the National Zoo in Washington to bid farewell to the giant panda "Baby" in the United States. "Baby" will leave for home on the 21st of this month. After that, the number of giant pandas in the Washington Zoo will be reduced to three, namely, the parents "Tian Tian" and "Mei Xiang" and the younger brother "Beibei".

　　In order to let people fully express their thoughts and wishes for the "baby", the zoo has prepared exquisite postcards. People can write messages on it and post them in the "mailbox". According to Allen Starbuck, a zoo worker, these postcards will go to China with the baby.

　　Stephanie Smith, who lives near the zoo, told China News Service that "Baby" is like her neighbor. She often walks to the Panda Pavilion to see it. She said that she likes "Baby" so much that it is hard to imagine what she will feel when she comes to the Panda Pavilion after it leaves. In order to see the "baby" more, she decided to come to the zoo to see it every day from the 16th.

　　Debbie Davis, a volunteer at the zoo, said that she witnessed the birth, growth and departure of Mount Tai, and now the same thing will happen to the baby. She said that in more than three years, she went to the Panda Pavilion countless times to see the "baby", but when it finally left, it was still very sad.

　　On the zoo website, the keepers of "Baby" wrote down the details of getting along with it day and night. Jenny Spoton wrote, "This is the first giant panda I have come into contact with since I worked. I watched it grow from the size of a butter stick to today. During this period, I have gained too many things. "

　　Stacy Taipola Rio wrote, "Sometimes it looks introverted, sometimes it looks active. At night, it will jump up and down, throw its toys around and have a good time. "

　　On the morning of 21st of this month, "Baby" will depart from Washington National Zoo and go to Washington Dulles International Airport. Later, it will fly to Chengdu, China on a cargo plane of FedEx.

　　The breeder Marty Dilry said that recently, they have been helping the "baby" adapt to its aviation box. He said with a smile, "Baby" has performed very well and may have fallen in love with its aviation box.

　　"Baby" is a crystallization of the cooperation between China and the United States in the field of giant panda research and protection, and it is also the messenger of Sino-US friendship. Netizen Heather Heckel left a message on the Facebook page of "Baby" on the 16th, saying, "Dear ‘ Baby ’ Thank you for letting us watch you grow up, for giving us hope for protecting endangered species, and for bringing the people of the United States and China closer together.

    University, here we come!

    On August 24th, more than 4,000 freshmen from all over the world became "Dongda people". Photo by Li Liu

    Since August 23, many universities in Jiangsu have ushered in the "Meng Xin" in 2024. The old campus with rich background and the new campus with new appearance are full of vitality. When the freshmen step into the campus with their bags and longings, at this moment, it is both a dream come true and a new beginning.

    Go to your alma mater together, and strive for youth to meet here.

    What’s it like to be alumni with mom and dad? At the scene, some new students visited the campus with their parents who had studied and lived in the same school.

    "My father is more familiar with the Gulou Campus than I am. I live in Room 2 of Taoyuan, and he lived in Room 12 of Nanyuan." On the morning of 24th, in the Gulou Campus of Nanjing University, Ruiqi Luo from Korla, Xinjiang, took a walk with his father on campus as soon as he cleaned up his dormitory. "My father is a Nantah native. He has been telling me about Nantah since he was in primary school. Since then, I have had the desire to apply for NTU. " When volunteering, Ruiqi Luo chose NTU Intelligent System Integration Experimental Class without hesitation. In 1990, after graduating from the School of Earth Science and Engineering of Nanjing University, Luo Dad chose to return to Xinjiang to join the construction of the western region. After returning to his alma mater many years later, Mr. Luo and his son "searched for roots" in the Gulou campus. "I am in the northwest and my heart is in Nantah. I hope that children can study hard in Nantah and become pillars of society! "

    "This is Dongda Auditorium, which is the former Institute of Technology. We used to study in the evening here …" On the 24th, Hu Yonghua, who returned to her alma mater, introduced her daughter Hu Xiaoyu incessantly. He and his wife Zhu Ping are both alumni of Southeast University, and their daughter was admitted to the "English+Information Engineering" double-degree major this year. Coincidentally, Xu Jingheng, who studied in Nanjing No.29 Middle School with Hu Xiaoyu, was also admitted to this major, while Jamlom’s parents were alumni of Southeast University majoring in management science and engineering and regional economics in 2002.

    Returning to the campus with the children again, Xu Jingheng’s parents also recalled the lush years of that year. "At that time, I lived in Room 9, Wenchang, Sipailou Campus, and my wife’s dormitory was behind Liuyuan Hotel. At that time, I rode my bike from east to west with egg cakes to bring her breakfast every day …" Xu Dad said, smiling hard on his face. Xu Jingheng, who grew up listening to the "omelet story", designated Dongda as an ideal university in his freshman year of high school and kept fighting for it. "What touches me most is the unique cultural atmosphere of Dongda University. I hope to make more friends here and become a better self." Xu Jingheng said.

    Go back to the old campus to "seek roots" and go to the new campus to dream.

    Since Nanjing University started its "root-seeking school" in 2022, all the freshmen in the school have stayed in Gulou Campus. In Southeast University, 2,340 freshmen moved into the Sipailou campus this year, which is the first time in recent years that more than half of the freshmen reported to the campus.

    "Walking into the campus of Dongda University, walking into Wutong Avenue, what comes to my face is the profound cultural heritage!" "Have long heard of Neusoft Meian, finally saw it today. I hope that in the future, I can also’ chew the roots and do great things’. " During the welcome period, Southeast University opened the school history museum, Mei ‘an and Wu Jianxiong Memorial Hall, and carried out campus visits to let freshmen feel the cultural atmosphere of the 120 universities in the process of searching for the source. In front of Yongquanchi, the landmark building auditorium of Dongda University, the school also organized the activity of "Freshmen Parents Say". At the scene, freshmen and parents took the stage to express their wishes and hopes and cheer for a better future together. During the activity, freshmen also wrote a wish card "to themselves after four years" and sealed it for graduation.

    "Root-seeking" and "dream" are the key words on the day of registration. "We have noticed that many freshmen have special feelings for the Gulou Campus of Nantah. For example, Yang Zehao of Kaijia College, the first thing he did after reporting for the freshman training camp on August 19, was to punch in again with his photo taken with Peking University Building when he was 9 years old, thanking him for his fate with Nantah." Shi Jiahuan, deputy secretary of the Party Committee of NTU Freshmen College, told the reporter that the first year of college is a crucial period for freshmen to know the university, enter the discipline and start the future. Nanjing University has launched micro-resources for freshmen’s adaptive education, so that students can better integrate into the university, the city and the times. "Freshmen will set up their growth goals, understand the charm of the subject and find the right direction of their interests through the study of topics such as’ University and Mr. Da’,’ Adaptive Education for Freshmen’ and’ Yuhua Hong-the Power of Faith’." Shi Jiahuan said.

    In the brand-new Jiangnan University Jiangyin Xiakewan Campus, the first batch of 455 "Meng Xin" settled in. Simple architectural style and water landscape with Jiangnan flavor are in the same strain as those of Jiangnan University Headquarters and Yixing Graduate School, and various banners and signs welcoming new students can be seen everywhere. Freshmen of the School of Digital Technology and Creative Design also got many "small surprises"-from brand-new visual image design and visual expression based on college English abbreviations, to specially customized canvas bags and card sets, hand-drawn maps of Xiakewan Campus in Jiangyin, and to white paper fans that can be stamped, all of which reflect the sincerity and ingenuity of the college. "This university’ meeting ceremony’ is so interesting. I will study hard and hope to have my own design works in the future." Ding Wei, a freshman majoring in digital media art, said.

    Start new courses for new majors and cultivate new talents.

    The reporter learned that most of the freshmen in 2024 were born in 2006, and Southeast University welcomed the post-10 students.

    At the welcome scene of Dongda University, a 13-member "Xueba Group" attracted much attention. Tan Ruiqi from Fushun No.2 Middle School in Liaoning Province was the youngest of them. After three years in elementary school, two years in junior high school and two years in senior high school, Tan Ruiqi, who is only 14 years old, is the first post-10 s student in the history of Dongda University. "Learning itself is a very interesting thing. I enjoy every process of exploring the unknown, so I chose to take the college entrance examination in my second year of high school and want to invest the saved time in more creative university study." Tan Ruiqi said that when I was in primary school, portraits of scientists Qian Sanqiang and Li Siguang hung in the classroom, and I was moved after learning about their deeds. "I hope I can serve my country like them and be a useful person."

    When I first entered the campus, the dream of serving the country through science and technology was already in my heart. Just entering the Intelligent Manufacturing College of Jiangnan University (Junyuan College), freshman Song Zihan saw the robot that greeted them. "I liked robots very much when I was a child, and now I am very interested in new terms such as drones and autonomous driving. The Yangtze River Delta has a strong science and technology atmosphere, and I hope that I can also participate in the production of advanced robots in the future. "

    In order to cultivate future-oriented talents with new quality, many colleges and universities have implemented new training plans in the new semester. This autumn semester, the core course of artificial intelligence general education in Nanjing University, which has received much attention, officially set sail. The course is oriented to all freshmen, and through the knowledge system and training mode of deep integration of AI and various disciplines, AI literacy education is integrated into the training of top-notch innovative talents to help cultivate and develop new quality productivity. Southeast University has also created an action plan of "Artificial Intelligence+Education" for freshmen. Led by the Institute of Artificial Intelligence, the course of "Introduction to General Studies of Artificial Intelligence" has been built according to the categories of science, engineering, medicine and humanities, and an interdisciplinary virtual teaching and research section has been set up to serve the whole school’s "Artificial Intelligence +X" education, with 105 pilot projects.

    In Jiangnan University, the first four colleges that settled in Jiangyin Xiakewan Campus were officially unveiled on June 7 this year, further connecting industrial transformation and local economic development. Cao Ming, dean of the School of Digital Technology and Creative Design of the school, said that in order to meet the new needs of the industry, the design discipline of the school is being adjusted around intelligent technology and intelligent interaction. "For example, the curriculum design of digital media art majors is more inclined to interactive media and virtual interaction. Fashion design majors integrate smart wearable devices into teaching. In the overall curriculum system, the college will also join artificial intelligence courses for freshmen. " (Yang Pinping, Xie Shihan, Ye Zhen)

BYD’s DM-i hybrid technology is now a household name. Why can it stand out among the hybrid technologies of a large number of automobile brands? As we all know, BYD’s hybrid cars have a history of more than ten years, and as early as 2008, a plug-in version of F3 was introduced. So why does today’s DM-i make BYD’s sales increase greatly, and what is the difference from the early hybrid technology? Let’s analyze it in detail from three aspects: motor, internal combustion engine and hybrid mode.

16,000 rpm motor and blade battery

DM-i is the abbreviation of Dual Mode-Intelligente dual-mode intelligence. Compared with the previous hybrid technology, it pays more attention to the use of motor, which is a hybrid technology of "electricity-oriented", with high-power motor drive, large-capacity battery power supply and internal combustion engine as the supplement, subverting the traditional hybrid "oil-oriented" design, which is a concept that really makes the fuel vehicle transition to new energy. In the past, the plug-in hybrid model was a fuel vehicle because the battery life was too short, and most people rarely charged when driving.

While BYD’s DM-i pays more attention to electrification. The maximum speed of the motor it carries is 16,000 rpm, with the highest efficiency of 97.5%, and the high-efficiency interval with efficiency exceeding 90% reaches 90.3%. Compared with the thermal efficiency of the fuel vehicle of about 40%, the energy utilization rate of the motor is higher. Because the instantaneous torque of BYD’s single permanent magnet synchronous motor exceeds 310Nm, it can completely replace the internal combustion engine, such as Song PLUS DM-i, which accelerates 100 kilometers.

The motor is equipped with a blade motor that has been safely verified in BYD’s pure tram. Combining the thermal stability advantage of lithium iron phosphate battery core, the blade structure makes up for the shortcoming of low energy density in Ferrous lithium phosphate, which achieves ternary lithium energy density and is safer. At present, the blade battery of DM-i has two capacities, of which the 8.3-degree version brings a cruising range of 51 kilometers; The 18.3-degree version brings 110 kilometers of battery life, of which 110 kilometers of battery life is close to Hongguang MINI EV, and commuters in urban areas can drive in pure electric mode.

1.5L hybrid engine with 43% thermal efficiency

After electrification, BYD developed Xiaoyun plug-in hybrid engine specially for hybrid vehicles. Taking the 1.5L self-priming version as an example, the braking thermal efficiency (BTE) is as high as 43%, which is the key to fuel economy. In order to achieve a record thermal efficiency, the engine has several core technologies.

First of all, compared with turbocharging, naturally aspirated air has a lower intake temperature, which can increase the compression ratio of the engine. By using pistons and connecting rods with higher strength, the compression ratio of Xiaoyun engine is as high as 15.5:1, which exceeds Mazda’s famous 14:1 (European version) Chuangchi Blue Sky engine. In the process of supercharging and compression ratio, in order to prevent knocking, the intake valve is opened in advance in the compression process through the variable timing mechanism of intake and exhaust valves, so as to solve the problem of cylinder pressure, make the expansion ratio greater than the compression ratio, and the larger expansion ratio converts more energy from heat to useful mechanical energy, thereby increasing the thermal efficiency.

This fuel-saving method brings the problem of low power density. The torque at low speed is very low. The torque of a turbine engine with the same displacement can reach 300Nm, while the peak torque of this engine is only 135Nm, and it needs to reach 4,500 rpm to explode. It is obviously not enough to drive the whole vehicle alone, but when it is used in a hybrid vehicle, the low speed is completely driven by a motor, so there is no problem of low starting torque.

Another advantage of blending is that the engine parts are electrified, and the traditional front engine parts drive system, such as air conditioning compressor, mechanical vacuum pump and mechanical water pump, is cancelled, which further reduces wear and improves efficiency. Cooperate with variable displacement oil pump to reduce oil resistance during cold start.

Xiaoyun hybrid is the first time BYD has installed split cooling for the engine. By measuring the temperature of cylinder head and cylinder block on demand, accurate cooling effect can be provided to achieve the optimal operating temperature of the engine, especially in winter, which can reduce heat loss, shorten the engine preheating time after cold start by 20% and reduce the fuel consumption of hot cars.

Four completely different driving modes

DM-i is mainly powered by electricity. When the power is sufficient, it is driven by pure electricity in urban areas, especially in traffic jams. The starting torque of the motor is large and it is easy to change lanes and overtake.

In the second case, the power is insufficient, the driving computer automatically switches the HEV series mode, Xiaoyun internal combustion engine enters the power generation mode, and the motor is still responsible for driving.

In the third case, if you are driving on a mountain road or want to experience the abundant hybrid power, you will enter the HEV parallel motion mode at medium and high speed (above 60km/h), and the motor and internal combustion engine will drive the car at the same time.

The fourth is high-speed cruise driving, which is directly driven by a 1.5L internal combustion engine. This is the stage with the highest engine efficiency, just like the 90km/h high-end and low-speed of an ordinary fuel vehicle. Although driving at high speed, the fuel consumption is low.

Car detective’s point of viewByd changed the early hybrid internal combustion engine, and then added the "chicken ribs" of the motor. DM-i started from three aspects: hybrid internal combustion engine, blade battery and high-efficiency motor, and developed a hybrid car from zero, forming a pure electric drive form, without endurance anxiety. Even if the power is fed, the fuel consumption per 100 kilometers is only 4-5L, which really reduces the car cost. What do you think of BYD DM-I technology? Praise, comment and attention are our greatest encouragement, thank you!

In recent years, China Mobile Guangdong Company has accelerated the construction of Gigabit broadband, and has built more than 54 million optical ports in the province, with more than 23 million home broadband users, including nearly 5 million Gigabit broadband users, and launched a 2000M ultra-high-speed broadband service.

It is understood that there is a saying in the communication industry that "Gigabit is easy to enter the house, but 100 Mbps is difficult to enter the house", which means that although Gigabit broadband fttp has been realized, the WiFi signal in some areas of the house is weak due to unreasonable router placement, wall blocking signals and other reasons, which affects the online experience, and some users even mistakenly think that there is a problem with broadband quality. In order to solve the "last ten meters" network perception bottleneck of gigabit home, Guangdong Mobile and Huawei jointly launched FTTR all-optical WiFi networking service, which was launched commercially in Shantou in September 2020, and promoted the upgrade of "fttp" to "fiber-to-room". Up to now, more than 150,000 mobile broadband users in the province have used this service.

According to the relevant person in charge of Guangdong Mobile, the all-optical networking adopts the "1-N mode", that is, one optical gateway plus n optical routes, and each room is equipped with an optical route, and each optical route is directly connected with the optical fiber, truly realizing the whole house WiFi without dead ends. With the help of WiFi seamless roaming technology, when users go to different rooms, the network automatically switches without feeling. The peak download rate of 2000M broadband can reach 250MB/s, and a high-definition movie can be downloaded in ten seconds. Multi-terminals can watch 4K/8K ultra-high-definition videos online, play large-scale online games and even VR/AR games at the same time, and there will be no jam.

"With the support of ultra-high-speed broadband, new applications such as cloud computers and cloud games will develop rapidly." The relevant person in charge said that the cloud computer has no hardware such as CPU, memory and hard disk. Compared with purchasing a physical computer, the cost is lower, and users can access the data stored in the cloud and use various applications by accessing the network. Cloud games put operations, rendering, storage and other links in the cloud server, and the game screen is transmitted to the local screen in real time. With the ultra-high-speed broadband guarantee, large-scale games can be played smoothly with low-configuration terminals.

In addition, the 2000M+FTTR all-optical WiFi networking supports the parallel access of more than 200 smart devices, which not only meets the Internet demand of computers, tablets and mobile phones, but also provides sufficient space for the increasing access of smart home appliances, smart security, smart pension and other devices in the digital home scene.

It is reported that Guangdong Mobile is making efforts to build a professional team of intelligent engineers to provide users with convenient and efficient networking services. For users who choose FTTR all-optical WiFi networking, engineers come to the door to tailor the solution according to the actual situation, such as laying invisible optical fibers to the room, and will make every effort to install and repair the same day.

While vigorously promoting the upgrade of home broadband, Guangdong Mobile has also launched Zhenzhi e enterprise networking service for small and medium-sized enterprises to support thousands of businesses to improve quality and efficiency. FTTR-B networking services include professional engineers’ door-to-door, networking scheme design, personalized application customization, WiFi coverage optimization, intranet rectification and optimization, integrated wiring construction, equipment installation and debugging, network inspection and operation, worry-free after-sales and other whole-process integrated services, covering an area of 3,000 square meters, providing applications such as Gigabit broadband, Gigabit WiFi and cloud computers for small and medium-sized enterprises, and deeply meeting the needs of corporate office and cloud access.

　　"During the battle (referring to special military operations), any grievances should be put aside, and now the fate of the Russian nation is facing a choice." Russian President Vladimir Putin stressed in a televised speech on the 24th that the Russian armed forces have received the necessary orders to eliminate those who organized armed riots.

　　The day before, the Russian Federal Security Service announced that it had initiated a criminal investigation against Prigozhin, the founder of the Russian private armed "Wagner" mercenary group, on the grounds that Prigozhin "called for an armed rebellion". Subsequently, the Russian General Prosecutor’s Office also said that Prigozhin had been prosecuted for armed rebellion, which could be sentenced to 12 to 20 years’ imprisonment.

　　Prigozhin denied that his action was a "military coup" and called it a "just war", and refuted Putin’s accusation of "treason", saying that their purpose was to save Russia from corruption and other phenomena. Earlier, news spread on social networks in the name of Prigozhin accused Russian Defense Ministry troops of attacking Wagner’s mercenary camp, saying that Wagner soldiers suffered "great losses" and promised to respond. The Russian Defense Ministry denied these accusations, calling them untrue and an "information provocation".

　　At present, the Russian capital Moscow and other places have stepped up their vigilance and are strengthening their anti-terrorism measures. On the other hand, Wagner mercenaries announced their entry into Rostov region in southern Russia on the 24th, and entered Voronezh region in southern Russia on the same day, claiming to control a number of military facilities in the region. The British "Guardian" pointed out that the situation in Rostov, the southern part of Russia, is in jeopardy, and the turmoil in an area of strategic significance to Moscow may have a far-reaching impact on the Ukrainian crisis.

　　In fact, since the conflict between Russia and Ukraine, Wagner mercenary group has been fighting side by side with the Russian army on the battlefield in Ukraine, and is regarded as a key force of the Russian army on the battlefield. Why did the founder of Wagner choose to stab the Russian army in the back at this time? Where did the rift between Wagner and the Russian army come from?

　　From Putin’s Chef to Wagner’s Founder

　　Wagner Group calls itself a "private military company", while more countries call it a mercenary organization. Its business covers operational staff, military consultants, training guidance, intelligence reconnaissance and so on. The organization is controlled by Russian oligarch yevgeny Prigozhin, who is the owner of a luxury restaurant in Russia. As a catering service contractor with close ties with many Russian political and military units, he once hosted a Russian state banquet, so he was called "Putin’s chef".

　　Wagner Group opened its new headquarters in St. Peter’s, Russia last November, and it first entered the public eye in 2014. According to the British Broadcasting Corporation (BBC), in 2014, Wagner supported the pro-Russian forces in eastern Ukraine and participated in Russia’s actions in Crimea.

　　In the west, Wagner has direct contact with the Russian government and should be regarded as an agency, but the Russian government denies Wagner’s participation in official military operations. According to the Reference News, on the surface, Wagner has no direct relationship with the Russian regular army and has not been officially registered, but has participated in Russian military operations in Syria and Ukraine. According to the British military intelligence department, Wagner was the backbone of the war between Soledad and Bachmut.

　　Before the outbreak of the conflict between Russia and Ukraine, Wagner also operated in southeastern Ukraine, Syria, Libya, Sudan, Central African Republic, Mali and Mozambique. According to previous reports, Wagner armed forces have the most advanced weapons and their own artillery. Most of its original members are veterans, and some even participated in the war in Afghanistan. They are well-trained and can perform the most complicated tasks, and are known for their efficient and fast actions.

　　Prigozhin once claimed on the social platform Telegram that Wagner’s actions in Africa were "honest and fair" and only aimed at "defending African people, including those oppressed by bandits, terrorists and others". However, Gomoti, director of Sadeq Institute, a Libyan think tank, pointed out in an interview with the media that the intervention of Wagner Group in Libya led to the division and paralysis of the whole country.

　　Wagner is famous for his fierce fighting style. Kolesnikov, a senior researcher at the Carnegie Endowment for International Peace, once said in the Russian independent media Novaya Gazeta that "exaggerated cruelty" is the characteristic of Prigozhin. Marat Gabidulin, a former member of Wagner Group, said in his memoir that Prigozhin’s "totalitarian" decision-making style often leads to misjudgment and casualties. "Because he firmly believes that he is always right, he is a genius and often overestimates his ability."

　　The "frontline hero" in the conflict between Russia and Ukraine

　　After Russia launched "special military action" in Ukraine, the confrontation between Russia and Ukraine gradually evolved into a long-term conflict, and Russia launched some military mobilization. In this context, Wagner became an auxiliary supplementary force of Russian troops in Ukraine.

　　In January this year, the British Ministry of Defence said: "It is almost certain that Wagner now commands 50,000 soldiers in Ukraine and has become a key part of the Ukrainian campaign." The US Department of National Security also holds the same view that Wagner’s 50,000 people in Uzbekistan are mainly composed of 40,000 prisoners from Russian prisons and 10,000 contractors.

　　From the outside world, Wagner’s influence expanded in the conflict between Russia and Ukraine, especially in January this year, Wagner claimed to occupy the important town of Leidal in Donetsk. According to Reuters, Russia occupied the Ukrainian city of Bakhmut in May, which was regarded as the biggest victory of Russia in the past 10 months, and Wagner was the biggest "hero" of this victory.

　　Prigozhin claimed that 20,000 of his soldiers were killed in the battle for Bakhmut, and about half of them were Russian prisoners. They were promised that they would be free after fighting in Ukraine for six months. US National Security Council spokesman John Kirby said at a news conference in May that Wagner’s death toll may exceed 100,000 since he joined the Ukrainian battlefield.

　　Wagner claimed in May that he had established a "defensive front" in Bakhmut, which was denied by the Ukrainian army. According to the Guardian, after winning Bakhmut’s victory, Prigozhin made a speech to the people in Russia together with former arms dealer viktor bout and other hardliners, propagating his image of toughness, populism and anti-elitism, and attacking the "incompetence" of the Russian Ministry of Defense, which resonated with Russians who were dissatisfied with the progress at the front.

　　"Wagner" and the escalation of high-level contradictions in the Russian army

　　Although Wagner’s troops have been fighting side by side with the Russian regular army, Prigozhin often criticizes the top of the Russian Defense Ministry. He claimed that Moscow did not provide enough ammunition for Wagner’s troops, and even questioned Putin’s special military action in an interview with Russian political activist Konstantin Dolgov in May, saying that the initial goal was to "demilitarize" Ukraine, but the action backfired and made the Ukrainian army stronger.

　　Over the past few months, Prigozhin has repeatedly accused Russian Defense Minister shoigu of being "incompetent". Recently, the contradiction has gradually escalated. At the beginning of June, Prigozhin claimed that shoigu deliberately made Wagner under-supplied, and the ammunition shortage rate was as high as 70%, so Wagner would leave Bakhmut and hand over the front to the Ministry of National Defense. This move is regarded as a threat to the Russian Ministry of Defense. In addition, Prigozhin has repeatedly denied the "victory" announced by the Russian Ministry of Defense, saying that the Ministry of Defense tried to "steal" Wagner’s glory.

　　According to the Guardian, in early June, Wagner also detained Lt Col Roman Venevitin, a Russian military officer, and the Prigozhin Press Office posted a video questioning the officer on the social platform Telegram. Roman Venevittin opened fire on Wagner’s vehicle after drunkenness, accusing Wagner of stealing weapons, forcing mobilized soldiers to sign contracts with the organization, and trying to extort weapons from the Russian Ministry of Defense to incite "anarchy" on the Russian front. This incident once again exposed the rift between Wagner and the Russian army.

　　As the war progressed, the rift between the two sides expanded into a wider gap. The Russian Defense Ministry said on June 10th that the "volunteer troops" in Ukraine must sign contracts with them before July 1st. This is considered to be an attempt by the Russian government to gain more control over these organizations. Prigozhin has refused to sign the contract and attacked the "inefficiency" of the command of the Ministry of National Defense.

　　On June 13th, Putin expressed his support for shoigu’s initiative to put informal groups under central control. Putin believes that this can provide mercenaries with the same benefits as soldiers: "This is the only way to ensure social security, because if there is no contract with the state and no contract with the Ministry of National Defense, then the state’s social security has no legal basis." "We need to do this and do it as soon as possible." Other pro-Russian groups fighting in Ukraine, such as Kadyrov of Chechnya, have signed contracts with the Russian Defense Ministry.

　　This actually shows that Putin supports the Ministry of National Defense led by shoigu in the dispute between Prigozhin and shoigu. Analysts believe that perhaps it is for this reason that Prigozhin, unwilling to lose control of Wagner, chose to "fight to the death" when the deadline came.

All-powerful and crazy all his life, but he didn’t expect that in the end Huang…

Who can save Xu Jiayin?

He must be too eager for freedom and the fresh air of this colorful world, but in the face of the truth, he had to pay a heavy price for his past savagery.

After Xu Jiayin was arrested, Zhao Changlong became the chairperson of Evergrande Real Estate Group. Many people had guessed the outcome and were betting on Zhao Changlong’s timely delivery. Unfortunately, as expected, Zhao Changlong came and went in a hurry.

On November 30, Hengda Real Estate Group Co., Ltd. changed its industrial and commercial information. Zhao Changlong stepped down as chairperson and was replaced by Liang Weikang!

What medicine is sold in the gourd?

I think you understand very well,

Today’s Evergrande, wanting to make a comeback against the wind, requires not loud slogans and beliefs, but financial support. If slogans and beliefs can bring Evergrande back to life, how could Xu Jiayin be reduced to imprisonment?

To put it more bluntly, the things that Xu Jiayin couldn’t solve, Zhao Changlong took office and moved forward with a heavy load. If he could hold on for a while, if he couldn’t hold on, this scene would naturally appear. Xu Jiayin became a lesson from the past, and no one in the future could do anything because of powerlessness. Eventually, he was sent to the bars.

Xu Jiayin has shouted all the inspiring slogans, and has also lent all the banks that can lend money. Of course, the down payment delivered by the people is also used by him to make up for the west wall. At this time, no matter who is appointed as the leader of Evergrande, it seems to be in a state of helplessness, because no one can believe it anymore. Real money, even if thrown in, is like sinking into the sea….

Unless there is a possibility, that is

"The power of capital!"

At this time, if the blood of capital is channeled, Hengda Real Estate Group may still be able to thrive, but it should be noted that the capital channeling of small funds is of no avail. A few capitalists are willing to bet on Hengda’s hand. I think no one dares to gamble easily.

Three or two billion yuan of funds is just the tip of the iceberg for trillion debts. No one can risk their lives to push themselves into the abyss. At the moment when Zhao Changlong became the new chairperson, he knew in his heart how capable he was

His departure was not sudden, but had long been fixed.

If there is no strong backing, no matter who takes over Evergrande now, they dare not swear

"It’s inevitable",

I can only put it mildly

"We strive, we will work hard, we believe…"

No one dared to say what DingTalk said on the board. After all, no one is Xu Jiayin, and there is no courage that Xu Jiayin once had.

In the year before Xu Jiayin was arrested, knowing that Evergrande, which was heavily indebted to foreign countries, was still overwhelmed, he still filled thousands of home buyers with ecstasy soup. The slogans of guaranteeing the building turned into a big lie again and again, just like feeding the home buyers with reassurance. In fact, it is a cure for the symptoms rather than the root cause.

Zhao Changlong has been the new chairperson of Evergrande Real Estate Group for several months, and he has never dared to say too much. He has thought about his retreat, and some things are seen by the masses.

It is the key to make a comeback with what, not who will lay it out….

Since Zhao Changlong has stepped down, who will be the most disappointed person? I think everyone has already guessed, that is Xu Jiayin, who can save him? If Evergrande goes against the wind and turns everything around, if Evergrande continues to change generals, it will only let thousands of people see the crisis and test that Evergrande is facing, and Xu Jiayin’s return to the rivers and lakes is even more distant.

As for Liang Weikang, the new chairperson of Evergrande Real Estate Group, I don’t know how long he can stay in this position. The most worrying thing is that the buyers have transferred their trust in Xu Jiayin to Zhao Changlong, and from Zhao Changlong to Liang Weikang!

Responsible editor:

2024 is almost halfway through, and NIO recently released its 2024 Quarter 1 earnings report and delivery data for May. At present, NIO’s overall market performance cannot be said to be much worse, but it is not particularly good.

First of all, NIO’s revenue declined slightly. The financial report shows that Quarter 1 revenue is 9.91 billion yuan, which is down 7.2% year-on-year compared with 10.676 billion yuan in the same period of 2023, and 42.1% month-on-month. At the same time, NIO’s vehicle gross margin fell from 11.9% in the fourth quarter of last year to 9.2%, and the loss further expanded to 5.185 billion yuan, an increase of 9.4% year-on-year. The situation is not good.

It is said that NIO has been burning money. In terms of R & D expenditure, NIO Quarter 1 invested 2.86 billion yuan, which narrowed a lot compared with 3.97 billion yuan in the fourth quarter of last year. It is already 2024, and some new car-making forces have turned losses into profits. NIO still has not been able to achieve profitability, which is obviously not conducive to development. Even if NIO still has 45.30 billion yuan in cash reserves, it is not a good way to burn money like this.

NIO’s sales performance is indeed tepid now. Quarter 1 delivered a total of 3,053 new cars, a decrease of 3.2% year-on-year and a decrease of 39.9% month-on-month. Compared with the previously expected target of 31,000 to 33,000 vehicles, it is still a little bit short. However, in late March, NIO made a little adjustment to Quarter 1’s delivery forecast, lowering it to about 30,000 vehicles, which is considered a "clever" target.

In fact, NIO’s recent sales performance is still a little improved, May delivery of 20,544 vehicles, in April delivered 15,620 new cars, all achieved year-on-year growth. According to the second quarter delivery guidance given by NIO, it is expected to deliver 54,000 to 56,000 vehicles, as long as the June delivery of 17,000 to 19,000 new cars, basically can achieve the goal.

However, NIO had previously set a goal of delivering 230,000 vehicles in 2024 with great ambition, and the reality did not seem to be so smooth. From January to May this year, a total of 66217 new cars were delivered, only 28.79% of the overall goal was completed. In the remaining half a year, it is not small to catch up with the remaining progress.

Next, I am afraid that NIO can only pin its hopes on Ledao Automobile. The existence value of this second brand of NIO is originally to take volume, and it can also relieve the pressure on NIO’s operation to a certain extent. Li Bin once revealed that the operating goal of the Ledao brand is to maintain a gross profit margin of more than 15%. From the perspective of break-even, Ledao can achieve break-even when it reaches a monthly sales volume of 20,000-30,000 vehicles.

However, NIO wants to achieve a turnaround in a short period of time, it is obviously more difficult, after all, Ledao Automobile wants to achieve 20,000 – 30,000 monthly sales results, not to say that it can do things, with the current market competition intensity, can break through 10,000 cars are already very good.

Car Online ReviewWhat is it?NIO, which focuses on the mid-to-high-end market, has been bound by its own brand positioning from the very beginning. It is undeniable that relying on its high-end image, NIO has indeed made a name for itself, but down-to-earth products are often more marketable. Now that NIO has begun to put down its position to make money, this step will have to be taken sooner or later. As for whether this step can go well, this is the most concerned thing in the entire industry and NIO’s large and small shareholders.
