Spring in Ma ‘an Village

Xinhua News Agency, Guangzhou, February 27th (Reporter Wang Ruiping) When the Sanhua plum beside the village road blooms a little bud, Ma ‘an Village is also ushered in spring with more than 30,000 mu of bamboo forests around it.
Ma ‘an Village, Pingtang Town, Xinyi City, Guangdong Province, located in the depths of Yunkai Mountain, is more than 800 meters above sea level and more than 1,000 meters above sea level. The mountains are high and the valleys are deep, and the land is barren. The villagers once used "nothing but steep slopes" to describe their remoteness and poverty.
"I have to walk on the dirt road hanging on the ridge for more than an hour every day when I go to school. I bring my own rice and leftovers. At noon, I use three bricks to build a stove to cook." Zhou Qinglian, born in 2002, recalled that her childhood journey to school was full of bitterness. Today, although her face looks immature, she has been working for almost two years after graduating from college and is a reserve cadre of Ma ‘an Village Committee.
Zhang Yujiao also chose to go back to the village for employment. In 2023, she graduated from Guangdong Ocean University majoring in economics and joined the Ma ‘an village tourism development and operation enterprise, becoming the "new generation" of local rural revitalization. "I used to study hard to get out of this mountain, but I didn’t expect to return to my hometown after graduation." Zhang Yujiao, dressed in fashionable clothes, wore Chinese hairpins and a horse-faced skirt, while receiving tourists, told reporters the story of employment at home.
It depends on the earth-shaking changes in Ma ‘an Village to attract college students to return to their hometowns for employment. In June, 2021, Yunmao Expressway was officially opened to traffic, which ended the history of no expressway passing through the eastern mountainous area of Xinyi City, narrowed the time and space distance between the mountainous area of western Guangdong and Guangdong-Hong Kong-Macao Greater Bay Area, and Ma ‘an Village also ushered in a new life.
The new look of Ma ‘an village (photo taken on February 12, drone photo). Xinhua News Agency reporter Wang Ruiping photo
More than 30,000 mu of bamboo forest around Ma ‘an Village is the biggest local feature. In August 2022, the rural revitalization project of "Ma ‘an Zhuhai" officially started construction. As an important node in the "Demonstration Zone of Rural Revitalization along Yunmao Expressway" carefully built by the local government, the project is jointly invested by the government and enterprises with a proportion of 250 million yuan, and the construction and management are not lower than the national 4A-level tourist attractions.
"The first exit of Yunmao Expressway in Xinyi is our Pingtang Town. We have the largest bamboo forest in western Guangdong, with alpine meadows, lakes, clouds and patches of virgin forests."
Xiao Yingbei, secretary of the Party branch of Ma ‘an Village, took the reporter across the rest pavilion hanging with "cooking tea around the stove" from the entrance of the renovated village Committee, along the asphalt road, through the hydrophilic platform with flowing water, climbed up the hotel and homestay in the middle of the mountain, and went around to Zhuhai Square in the middle of the village. As he walked, he introduced that Pingtang Town used to be the "leftover material" of Xinyi City, and Ma ‘an Village was the "leftover material" of Pingtang Town. Now the traffic is good.

"Just after the Spring Festival, several friends from other places wanted to visit our village and asked me if there was a traffic jam." Yang Xiangwen is usually engaged in logistics and distribution work in Baiyun District of Guangzhou. After dinner with friends, he walked to Zhuhai Square. He took the reporter’s hand and said, "Now I am very proud to tell others about our village. There are many videos of our village on my mobile phone, which others envy!"
Tourists took a group photo in Ma ‘an Village (photo taken on February 12). Xinhua News Agency reporter Wang Ruiping photo
In the reception room of Ma ‘an Village Committee, the wall is a new panoramic photo of Ma ‘an Village. Xiao Yingbei broke his fingers and analyzed the situation of the scenic spot after it was opened to reporters. In 2022, the collective income of our village was only about 170,000 yuan, and it has increased to 963,000 yuan in 2023. "Ticket income, house rental, parking fees, operating share of hotels and homestays, plus homestays run by villagers, restaurants and canteens can all increase villagers’ income."
According to the planning of Ma ‘an Village, after the "Ma ‘an Zhuhai" scenic spot is opened normally this year, the per capita annual equity dividend of villagers can reach 2,000 yuan, providing 200 jobs, and more villagers will also find jobs at their doorsteps.
"In the past, the village was a winding mud road, but now it has expanded into a 5.5-meter two-way lane." Zhou Qinglian said that every time the hometown road is widened, the life of the villagers will become better.
Driving from the top of the mountain to Yunmao Expressway, the clouds spread over the bamboo sea from the valley, and countless bamboo shoots were buried in the soil at this time, calling for spring rain. When the spring thunder rings, these spring shoots will bring different spring to Ma ‘an village.

[Network China Festival] Lantern Festival: Regaining the breath of life and waiting for the reunion of thousands of families.

  The stars and the moon are burning in the sky, and there are two yuanxiao on earth. Every year, it’s Lantern Festival again.

  Lantern Festival, also known as "Shangyuan Festival". In this festival, in addition to eating dumplings, enjoying lanterns and solve riddles on the lanterns, there are also countless literati who have left many poetic poems. These poems, or trigger the resonance of missing, or contain similar warmth, as well as countless inner attachments. These beautiful images hidden in ancient poems have amazed the time and the soul.

[Network China Festival] Lantern Festival: Regaining the breath of life and waiting for the reunion of thousands of families.

  Today, let’s walk in poetry and feel the Lantern Festival in poetry.

  Ouyang Xiu wrote in the Northern Song Dynasty: "On the Lantern Festival last year, the flower market was lit like a day. The moon rose above the willow tree, At dusk he had a tryst with me. The lantern festival on the fifteenth day of the first month of this year, the moonlight and the lights are still the same as last year. I didn’t see last year, and my tears wet my spring shirt sleeves. " Just a few crosses create a hazy, quiet, graceful and soft artistic conception, which makes people feel the charm of China’s traditional poems.

  "Jin Li Fang Yan, Lan Hongyan in his early years. The color is far away, and the light is far away. After the Chinese suspect that the stars are falling, the building is like a moon hanging. Don’t have a thousand gold smiles, come and reflect the nine branches. " Lu Zhaolin, one of the four outstanding figures in the early Tang Dynasty, wrote a poem "Watching Lights at Fifteen Nights", which made the colorful Lantern Festival lights unique and brought people into the enchanted fairyland.

  The poet Su Weidao wrote in the poem "The fifteenth night of the first month": "The fire tree and silver flowers are combined, and the star bridge is locked. The crowd surged, the dust float in the sky under the hoofs of the horses; Moonlight all over every corner, where people can see the moon overhead. Prostitutes are all ruined, and songs are all ruined. Jin Wu can’t help but stay up at night, and the jade leaks. " The poem describes the scene of lights scattered and crowds surging on the Lantern Festival night in Chang ‘an, and people still don’t want to leave at midnight. Read it carefully, and you will have a wonderful feeling of being in the capital of Datang and sleepwalking in the sea of people and lights.

[Network China Festival] Lantern Festival: Regaining the breath of life and waiting for the reunion of thousands of families.

  Yuan midnight snack, between the lights. "Find him thousands of baidu in the crowd. Suddenly looking back, the man was there, and the lights were dim. " Xin Qiji, a poet in the Southern Song Dynasty, is well-known for this word in "Qing Yu An Yuan Xi". In fact, in ancient times, Lantern Festival was also a romantic festival. Lantern Festival provides an opportunity for unmarried men and women to get to know each other, and it is also a good opportunity for young men and women to meet their lovers.

  In the Song Dynasty, the anonymous poet "Partridge Sky Shang Yuan" said: "At dusk, we welcome the auspicious to the Royal Return, and the palace flowers carry the brocade in piles. The whip sounded by the bridge in Tianjin, and the shadow was opened in front of Xuande Building. Play Shun music, enter the Yao Cup, and announce that the car will go to Tianjie immediately. The king likes to have fun with the people, and he comes with shock on all sides. " It describes the grand occasion of the Lantern Festival in the capital city of Song Huizong, where the emperor enjoyed the fun with the people, the officials and petty officials swarmed around, and the people flocked to it. Everyone wore all kinds of flowers on his head, and all the way, it was colorful and dazzling, as if it were a sea of flowers.

  Tang Bohu, a cynical and talented six-legged layman, also wrote a beautiful work "Yuanxiao". "A moon without lights is not entertaining, and a moon without lights is not spring. Towards everywhere spring comes as seen here with lady fair, Over bright moonlit night flashing lanterns set off the moon as pure silver. All over the street, Zhu Cui swims around the village girls, singing and competing with the social gods. If you don’t show your respect and smile, how can you get rid of this good time? " The Lantern Festival written by him is not only beautiful in artistic conception, but also lively and touching. The lights and the moon are shining, the songs are everywhere, and even the village girls wear red and green to travel. The scene is very spectacular and moving.

  The beauty of poetry lies in its rich flavor of the times and life. The romance of poetry lies in its engraving of human experience and customs changes. Therefore, it can cross the long river of time and let us regain the memory of culture. No matter how time and space change, Lantern Festival is still a spiritual symbol that we can’t give up, and people are still used to reunion in festivals.

  "At the Lantern Festival last year, the flower market lights were as bright as day. On the first night of this year, only the moon remains. " On this day, which should be a family reunion, too many people can’t do so because of the unexpected visitor "COVID-19 epidemic". This sudden epidemic has disrupted the rhythm of everyone’s reunion and disturbed our pace of going home. At this moment, on the Lantern Festival, let’s say a word to the "soldiers" who are fighting against the epidemic: take care and be safe! Say a word to all my family and compatriots: Happy holidays!

  The fight against the epidemic has entered the stage of Armageddon, and we look forward to the early dispersal of the epidemic and the family reunion as soon as possible! (Guangming. com reporter Yuan Qing)

Another first time in 34 years: the Chaozhou opera "Watching Lights" made its debut at the CCTV Lantern Festival.

  CCTV’s 2019 Lantern Festival Gala will be held soon. Southern Reporter learned that Chaozhou Opera, one of the four famous dramas in Guangdong, will be on CCTV Lantern Festival Gala, and Zhang Yihuang, winner of China drama "Plum Blossom Award", and others will show the charm of Chaozhou Opera "Watching the Lights". The famous artists who appeared in this performance are Zhang Yihuang, Lin Chufa, Ant yan dan and Zhang Shutong. Like the Spring Festival Gala, the CCTV Lantern Festival Gala has also attracted much attention. This is another famous Guangdong drama on CCTV Lantern Festival Gala after Guangdong Cantonese Opera on CCTV Spring Festival Gala.

  Chaozhou Opera, one of the four famous operas in Guangdong (Cantonese Opera, Chaozhou Opera, Han Opera and Lei Ju), was named after its formation in Chaoshan area of Guangdong, commonly known as "Chaodiao", "Chaoyin Opera" and "Baizizi Opera". It was widely circulated in Zhao ‘an, Yunxiao, Pinghe, Dongshan, Zhangpu and Nanjing in southern Fujian in the late Ming Dynasty, and was closely related to Liyuan Opera. In 2006, it was selected into the first batch of national intangible cultural heritage list. Known as "southern flowers".

  "Watching Lights" Dressed Rehearsal

  Plays: Meet a beautiful woman under the Lantern Festival, and a beautiful marriage is made by a mirror.

  The performance program is "Watching Lights" from the classic drama "Li Jing Ji" of Chaozhou Opera.

  Li Jing Ji originated from Chaozhou and Quanzhou in southern Fujian, mainly in the form of Qupai (script), and was performed by drama. The Chaozhou opera Li Jing Ji, also known as Chen San Wu Niang, is written in Chaozhou dialect and Quanzhou dialect, which is the earliest publication in Minnan language and the most representative traditional repertoire of Chaozhou opera.

  The story tells that Chen San, a native of Quanzhou, Fujian Province in the Ming Dynasty, sent his brother and sister-in-law to Guangnan to take office. On the Lantern Festival, he passed through Chaozhou, Guangdong Province, and met Huang Wuniang, a rich daughter, at the Lantern Festival. They fell in love at first sight and loved each other. Huang’s father was greedy for money and love power, and allowed Wu Niang to marry Lin Da, a rich man. Wu Niang was dissatisfied and depressed. Chen San came to Chaozhou again and passed by Wuniang Xiulou, where Wuniang threw lychees and handkerchiefs to show her love. Chen San disguised himself as a mirror grinder and entered Fu Huang. When Chen San was grinding the mirror, he deliberately broke the mirror and sold himself into slavery on the pretext of losing the mirror. After twists and turns, Yichun tactfully helped pull strings, and Chen San and Wu Niang finally escaped and eloped back to Quanzhou. This drama has a distinctive color of rebelling against feudal ethics, eulogizing the free marriage of men and women, and breaking the vulgar marriage arrangement of men and women in feudal society. The whole drama has strong local cultural characteristics and has been performed for a long time. Watching Lights, Collecting Books, Keeping an Umbrella and Contracting in the drama have become immortal classics of Chaozhou Opera.

  Fang Zhanrong, a national representative inheritor of Chaozhou Opera and former head of the 2nd Troupe of Guangdong Chaozhou Theatre, introduced that the performance of "Li Jing Ji" and "Watching Lights" at the CCTV Lantern Festival was a brilliant scene and a classic fragment, among which, four professions representing Chaozhou Opera will be presented to the national audience one by one. Fang Zhanrong is a famous and ugly Chaozhou Opera. He devoted himself to its promotion all his life. He said that Chaozhou Opera is more difficult to promote than other local operas because it is performed in dialects. "But this is also our ambition. As an ancient opera, it is great that local operas in languages that are not easy to learn can be put on the CCTV Lantern Festival." Fang Zhanrong introduced that Chaozhou Opera has also been put on the central opera channel many times. He said that CCTV Lantern Festival Gala is a national event.

There’s a reason for playing billiards too badly. The exclusive cheats teach you how to clear the table with one shot.

"Source: Institute of Physics, Chinese Academy of Sciences"
Whether table tennis is good or not depends on fate, and some people believe in "making great efforts to make miracles".
Some people think that through constant practice, they can naturally master those wonderful hitting angles and achieve perfection.
Do you know how hard I work?
But in fact, the way of hitting the ball and the trajectory of the table tennis game contain rich knowledge of mathematics and physics. This knowledge controls the trend of table tennis, and you can also become a master of table tennis by mastering these theoretical knowledge.
Essential knowledge 1: sine theorem
If we regard point A as a white ball, point B as a target ball and point C as a hole, how can we achieve the goal?
At this time, understanding the sine theorem can help you find the best goal plan. The formula of sine theorem is as follows:
In this formula, r is the radius of the circumscribed circle of the plane triangle ABC.
Essential knowledge 2: cosine theorem
Similarly, in any triangle in the above picture, the rational use of cosine theorem formula can also help you find the best scheme to hit the ball B into the hole C with the white ball A.
The cosine theorem is as follows:
Essential knowledge 3: reflection theorem
As shown in the above figure, red is the initial motion line of the ball, blue is the reflection line of the ball, the gray rectangle can be regarded as the edge library of the table, and the purple midline is the normal vector in the middle of the interface, so the following hypothetical figure can be obtained:
Through this reflection pattern hypothesis, we can better imagine the trajectory of the ball after hitting the library.
Essential knowledge 4: collision principle
① Frontal collision (completely elastic)
After the collision of two objects, the kinetic energy and momentum of the system are conserved, and there is no additional energy conversion.
The conclusion is:When the two balls have the same mass, the speed of the two balls will be exchanged after a completely elastic ideal frontal collision.
② frontal collision (totally inelastic)
Inelastic collision means that a part of the kinetic energy of objects is converted into internal energy before and after collision, while completely inelastic refers to converting kinetic energy into internal energy as much as possible, that is, two objects move at the same speed together.
③ Actual collision
The actual collision is a mixture of completely elastic and completely inelastic collision. If the velocity of the two balls is defined as V1,1, V2, 1 after a complete elastic collision; Before the collision, the speed of the two balls was V1,0, V2,0, and the recovery coefficient of the resin material used in billiards was k (the recovery coefficient of good materials was k≈1), so there were:
When k=0, it is completely inelastic collision, and when k=1, it is completely elastic collision. For an actual collision problem, the transformation of velocity and internal energy after two balls collide can be expressed by k, which is specifically expressed as:
In addition, it includes image vector decomposition; General situation and special situation of two-dimensional collision; Rigid body dynamics; Rotational inertia and rotational energy: rotational inertia of homogeneous sphere, law of rotation; Friction: a series of necessary knowledge points such as static friction, sliding friction and rolling friction …
Aiming technique
After a long and boring basic theoretical knowledge, you must be a patient and persevering table tennis enthusiast, and you also have the theoretical basis for learning more skills. Then if you want to master the secret of how to hit the ball in actual combat, aiming technology is the main content to be learned next.
I believe everyone understands a truth. When we observe an object, the closer it is to us, the bigger it will look. If it is farther away from us, it will look smaller. In fact, the actual size of the object has not changed. This is the so-called visual effect.
The visual effect will affect our judgment on the size of the cue ball, thus affecting our aiming angle.
So when we aim at close range, we will subjectively think that the ball looks big, while it looks small at a distance.
Then there are two problems that need to be discussed: first, the influence of the cue ball getting bigger on the thickness of the shot; Secondly, how much will the distance between the center of the cue ball and the goal point and the center of the target ball make the cue ball look bigger?
First of all, we will explain the impact of hitting thickness after the cue ball becomes bigger as shown in the above figure, which shows the maximum overlapping thickness of the two balls, the big gray circle is the size of the cue ball after it becomes bigger, the radius is, the small circle is the original size of the cue ball, the red ball is the size of the target ball, the radius is, and the maximum overlapping radius of the small gray circle and the red circle is, so there are:
The second question has the following explanation about the distance between the cue ball and each ball center. As shown in the above figure, D represents the distance between the cue ball and the goal point, and the distance D0 between the cue ball center and the target ball center, and the angles α and β, then the relationship between the variables can be obtained as follows:
Walking technique
Finally, let’s talk about the topic that everyone is most interested in, which is also the advanced skill of table tennis game-walking technique. Walking technology is to control the motion track of the cue ball by hitting different positions of the cue ball.
0:Center pole/fixed pole, ideally, the cue ball will only slide without any rotation.
1:High/heel/topspin, cue ball rotates forward, which has following effect after collision.
2:Low shot/shrinking shot/backspin ball, cue ball rotates backward and travels backward after collision.
3&4:Side plugs, 3 and 4 represent the left and right respectively, and the cue ball rotates to the right and left respectively after the shot, which can change the rebound angle of the cue ball after hitting the library.
5:Left plug, the effect is the superposition of high pole and left plug.
6:Upper right plug, the effect is the superposition of high pole and right plug.
7:Left lower plug, the effect is the superposition of low rod and left plug.
8:Lower right plug, the effect is the superposition of low rod and right plug.
A:Stearns followed, and the distance followed after the cue ball hit the target was shorter than that followed by the high pole.
C:Stern retreats, and the distance that the cue ball retreats after hitting the target is shorter than that of the low pole.
B&D:Stensey, the cue ball changes direction after hitting the target.
By hitting the above position of the cue ball, the corresponding cue ball movement effect can be achieved.
After learning so many high-end knowledge and formulas, let’s get rid of the old concept of "making great efforts to make miracles". Many people always keep the same strength to hit the ball, which is not desirable. The strength of hitting the ball should be changed at any time with different situations. This requires long-term practice to accurately grasp the strength of the shot that should be adopted at different angles.
The above is the explanation of the formula and technology related to this table tennis game. Dear table tennis lovers, remember the formula and practice hard. "Clear the table with one shot" is not a dream!

Let outsiders see jokes, no! Making this big country’s heavy weapon is to fight for making it in China.

  CCTV News:There are representative major projects and major projects in each era, and those super projects have become the symbolic symbols of the times, which embodies the hard work and creativity of the people of China and also witness the road of China’s revival and rise.

  Shield machine is a necessary equipment for tunneling, and it is also a high-end equipment focused on "Made in China 2025". At one time, the technology and overseas market of super-large diameter shield machine have been monopolized by western countries for more than a century. In May this year, the super-large diameter shield machine independently developed by China will go abroad for the first time and become a new "national business card" for China.

  In May, this super-large diameter shield machine with a diameter of 12.12 meters and a weight of 2,200 tons is about to leave for Bangladesh. Although it is the weekend, the manufacturing team is still making the final confirmation of the export shipment plan.

  For Zhang Boyang, the person in charge of this shield machine, it is not the first time that there is no weekend. The shield machine exported this time is not the most difficult project he took over. At the same location, they once manufactured the first super-large diameter shield machine with independent intellectual property rights in China — — "Tianhe", with a diameter of 15.03 meters and a weight of 6,500 tons, was used to excavate the Yangtze River tunnel in Nanjing at that time.

  Zhang Boyang, head of CCCC shield machine project: "This was the most difficult geology in the world at that time. It was soft on the top and hard on the bottom. If it was all hard, it would be easy and even."

  Zhang Boyang is the commander of Nanjing Yangtze River Tunnel Project. At that time, only one foreign company in the world had experience in manufacturing shield machines with similar conditions, and the construction party planned to order two shield machines from this company.

  Zhang Boyang, head of CCCC shield machine project: "700 million one, two 1.4 billion, no price reduction. You can’t rely on others to import all the time. Once they wean you from food, you will die, so we are determined to make it ourselves. "

  It’s better to throw off your arms and do it yourself than to cry your head off and beg for help. A big country’s heavy weapon must be in its own hands. As an engineer of this project, Zhou Jun was mainly responsible for research and development.

  Zhou Jun, Chief Engineer of CCCC Shield Machine Project: "The pressure is enormous. Everyone thinks it is incredible, and there are doubts outside."

  In the process of research and development, many technical problems appear for the first time, so we can only cross the river by feeling the stones. The research and development of core components has made everyone think hard.

  Zhou Jun, Chief Engineer of CCCC Shield Machine ProjectThe cylinder is the core component of the shield machine, and the shield machine moves forward by the thrust generated by the cylinder. Before that, they were all imported from abroad. Our super-large diameter shield cylinder is a luxury car, 500,000 yuan each. "

  Tianhe needs about 50 such cylinders. In order to realize the localization of core components, the R&D team made great efforts and made up their minds to gnaw this hard bone.

  Zhou Jun, Chief Engineer of CCCC Shield Machine ProjectWe employees are the earliest to get off work at 11 pm. I basically go to work after 7 o’clock in the morning and get off work around 1 o’clock, every day. Through four to five months of experiments, we have come up with a set of manufacturing inspection standards for large-diameter shield cylinders. "

  After nearly half a year of technical research, the domestic shield cylinder finally came out, and the cost of one cylinder was 300 thousand yuan cheaper than that of imported cylinders. A super-large diameter shield machine consists of tens of thousands of parts of different sizes. Behind every domestic part is hard work. The research and development of Tianhe has been designed, modified, tested and revised thousands of times. There are more than 7,000 drawings confirmed in the final design of the whole equipment, which are more than one person high when stacked together.

  Zhou Jun, Chief Engineer of CCCC Shield Machine Project: "Everyone thought the same thing as me at that time, that is, we built these two machines. At that time, China should be said to be the shield machine with the most advanced technology, the largest diameter and the highest difficulty. Everyone had this sense of accomplishment at that time, that is, this kind of glory for the country, this kind of courage, including this spirit, that is to say, since I have done this, I must do it well. "

  After 14 months of hard work, in July 2012, China’s first super-large diameter shield machine "Tianhe" was officially put into use, and the two shield machines saved nearly 800 million yuan for the country. However, can this shield stand the test of super engineering?

  Zhang Boyang, head of CCCC shield machine project: "The most painful thing was in 2013, when the cutter head got stuck. Just a few days before the Spring Festival, I didn’t leave the construction site for half a step, and I stayed in the shield machine for observation and analysis every day. "

  The cutter head suddenly stopped turning during the excavation of the Yangtze River tunnel, and these 59 days were the most difficult days for everyone.

  Zhang Boyang, head of CCCC shield machine project"This is not only an enterprise, but also the pressure from China people. You let foreigners see Chinese jokes. This pressure is really huge, even if you cut my meat. "

  After a long period of hard thinking, Zhang Boyang made a bold suggestion.

  Zhang Boyang, head of CCCC shield machine project: "I retreated the cutter head and shield body of this integral shield machine, which is technical and has never been seen before. But I also evaluate and analyze what risks it has, how to retreat, and how much strength it needs. I use the telescopic mechanism and oil cylinder of the cutter head, and every time I retreat 10 mm, 10 mm, that’s all. "

  After two months of persistence, the cutter head finally turned again. In July, 2015, after three years, Tianhe came out of the hole at the bottom of the river and saw the light again. Many people present cried with joy.

  Zhang Boyang, head of CCCC shield machine project: "Without responsibility, there is no innovative spirit. You dare not take responsibility, do you dare to innovate? We are not willing to do this. How can China’s manufacturing industry develop? "

  Tianhe has achieved 50% localization rate, and the localization rate of shield machines to be exported to Bangladesh has increased to 95%. It will be used in China’s largest overseas shield road tunnel project, and help the country’s "Belt and Road Initiative".

Go to the grassroots in the Spring Festival and stick to it for a better reunion —— A note on the New Year’s Eve run of Shenzhen Express Takeaway Brother

  Xinhua News Agency, Shenzhen, January 22nd Title: Stick to it for a better reunion — — Shenzhen Express Takeaway Brother’s New Year’s Eve Running List

  Xinhua News Agency reporter Zhao Ruixi

  In the early morning of New Year’s Eve, Yang Lei went out on his electric car and was busy collecting and dispatching parts in several communities in Shenzhen Nanshan Science and Technology Park. This is his 17th year as a courier. He can’t remember how many times he received the delivery on New Year’s Eve. "After working as a courier, he didn’t go back to his hometown for the New Year."

  On the morning of January 21st, at the gate of the residential area to be delivered, Yang Lei moved the boxes of express delivery out of the car. (Photo by Xinhua News Agency reporter Liang Xushe)

  "My wife and two children are in Shenzhen. Many younger brothers’ families are not around, giving them the opportunity to go home. " Yang Lei said, "The company will also give rewards for going to work during the Spring Festival, and give compensatory time off after the holiday. My wife works in a supermarket and also works during the Spring Festival. Both children are in junior high school, they can understand us, and they can also heat their own meals and take care of themselves. "

  This year, SF Express, where Yang Lei is located, set up a special incentive package and warm-hearted care activities for the Spring Festival totaling more than 400 million yuan to encourage employees to stick to their posts.

  Yang Lei told reporters that the peak of receiving and dispatching parts is before the Spring Festival, and the workload during the Spring Festival is not too heavy. He, who is usually responsible for receiving and dispatching office buildings, went to support the receiving and dispatching work of residential quarters during the Spring Festival. In the four hours in the morning of New Year’s Eve, he received more than 80 tickets. "Under the superposition of various incentives, the Spring Festival can earn more than 10,000 yuan this month."

  On the morning of January 21st, Yang Lei (former) was busy sorting express delivery. (Photo by Xinhua News Agency reporter Liang Xushe)

  Near noon, Yang Lei was almost busy with the delivery task in the morning. At this time, Shen Jinfeng, a takeaway rider in Longhua District, got busy and rode his electric car between the restaurant and the community.

  In 2021, Shen Jinfeng joined the US Mission and became a full-time takeaway in Longhua Minzhi District. He said: "Takeaway is an industry with more work and more rewards. As long as you are willing to pay, you will get a reward." In order to earn more money, he has chosen to stay alone in Shenzhen to deliver meals during the Spring Festival for two consecutive years.

  Meituan has invested more than 500 million yuan this year as a subsidy for riders to stabilize their posts during the Spring Festival, including the subsidy for staying in the post, the red envelope for starting the Spring Festival, the red envelope for duty, and the subsidy for stepping back to work.

  On New Year’s Eve, there were not many take-away orders. Until 1 pm, Shen Jinfeng sent out a total of 10 takeaways. "Although there are not many orders, the delivery fee per order is much higher than usual. I earned more than 9000 yuan in the Spring Festival last year. This year’s Spring Festival will get all kinds of rushing rewards, and you can earn more than 10,000 yuan. " Shen Jinfeng said, "earn more money and go back to your hometown in Anhui on the fifteenth day of the first month to reunite with your family."

  In addition to strengthening the incentive mechanism for enterprises, the government has also taken action. Years ago, the relevant departments in Shenzhen made it clear that the express delivery and take-out during the Spring Festival would be subsidized by the municipal finance for each order in 1 yuan. Front-line workers in construction, tourism, sanitation, manufacturing and other industries can also receive corresponding government subsidies.

  "Although the Spring Festival is not around my family, I am very happy to deliver the meal to the guests in time so that they can have a hot meal and have a happy year." Shen Jinfeng said.

  Yang Lei said that nowadays, the society generally recognizes the courier brother more. During the Spring Festival, it is still relatively happy to ensure that residents receive the needed items in time and have a good year. "A package sent every day conveys a love." He said.

  They are the epitome of tens of thousands of little brothers who stay deep in the post during the Spring Festival, contributing to the better reunion of others and working hard for their own better reunion. Shen Jinfeng said: "I believe that the good days are still behind!"

How do senior three students prepare for the exam when the countdown to the college entrance examination is less than 100 days?

  This year, the number of college entrance examination candidates in China is expected to exceed 10 million. Weng Tiehui, Vice Minister of Education, said at the press conference of the joint prevention and control mechanism in the State Council on February 28th that the Ministry of Education will carefully study the implementation plan of this year’s college entrance examination, and relevant work arrangements will be announced to the public in time. The reporter found out that since the resumption of the college entrance examination, the college entrance examination has never been rescheduled for any reason. Even during the SARS period, the original plan was still implemented, one month ahead of the previous year, and it was carried out normally. According to the usual arrangement, the 2020 college entrance examination will officially enter the 100-day countdown on February 28th. How to stay in the sprint stage and get rid of the adverse effects caused by the epidemic has also become a challenge that this year’s senior three students must go all out to face.

  Recording and broadcasting lectures, live answering questions, opening the "online teaching" mode in the third grade of senior high school.

  Wang Yi, director of the third grade of Wuchang Experimental Middle School in Hubei Province, told the reporter that the "online preparation" model carried out by the school has been going on for more than a month due to the epidemic.

  Wang Yi said: "We started our holiday on January 20th. We originally planned to start classes on February 1st, the eighth day of the first month, and the winter vacation lasted for 10 days. Due to the sudden outbreak, online teaching has become a routine mode. Before that, to be honest, most of our teachers, including myself, taught online ‘ Zero foundation ’ . I thought at that time, I would take advantage of the winter vacation to explore. I had a holiday on January 21st, and I started to broadcast live on the Internet on the 22nd … …”

  With the development of the epidemic situation, in late January, the Ministry of Education announced that schools all over the country should "close classes without stopping studying", integrate online learning resources according to their own reality, enrich learning content, and provide suitable home learning methods for candidates.

  Wang Yi led the team to take action formally. He introduced: "On the fifth and sixth day of junior high school, I suggested to the school to hold a video conference through QQ group to let the teachers get familiar with the operation. After four or five meetings, everyone gradually became proficient, brainstorming and communicating with each other, and this kind of teaching channel was gradually established. "

  Designated e-mail to send and receive grading homework, mobile phone applet to conduct quizzes, and online simulation exam to test learning results … … After two weeks of exploration, the online teaching feedback mode in this special period has been continuously enriched and improved.

  Li Huisuo, secretary of the Party Committee and president of Hebei Hengshui School, introduced in an interview with CCTV News 1+1 that Hengshui School has taken three measures to help senior three students prepare for the exam: 1. All the students participate in student management: a teacher subcontracts several students for video home visits and individual counseling to keep abreast of their situation; 2. Expand the content of education in an all-round way: the cultural class adopts the way of combining recording and broadcasting teaching with live answering questions; Physical education class arranged gymnastics suitable for family exercise; Carry out labor education classes and let students do some housework. 3. Highlight inspirational education in the whole process: record inspirational theme class meetings and inspirational micro-videos to keep students energetic.

  Parents of online exams and home exams turned into "invigilators"

  From January 30 to February 11, the teaching and research staff of senior three in Wuhan began to develop and revise the February research examination questions in Wuhan online, and completed the online and offline versions of 9 sets of papers. On February 26th, relying on the Wuhan Education Cloud Platform, the city’s senior high schools were organized to carry out the online quality testing of senior three English subjects, and the feasibility of online quality testing of senior three English subjects was studied and analyzed, which also provided a practical basis for the online quality testing of senior three English subjects in Wuhan in the future.

  Su Min, the educational director of Wuhan No.11 Middle School, said: "We have designed an online exam, which is called the heart-taking exam, to make students transition from the loose state of holidays to the tense state of study as soon as possible. There is a weekly test once a week to test the learning state of the week. There is a monthly exam once a month to understand the learning status of the whole month. Teachers can fully understand students’ learning situation through testing and adjust their own teaching. Students can also check for gaps and make timely adjustments, and at the same time, they can also conduct sufficient exercises to hone their skills, speed and mentality. "

The cloud system invigilation of Guangqumen Middle School in Beijing

  On March 3rd, the first adaptive test of Beijing New College Entrance Examination was held. Affected by the epidemic, more than 50,000 candidates took the "home exam" for four consecutive days.

  According to the different conditions of each school, the test papers reach the candidates by flash mail, on-site collection by parents, and self-printing by mailbox extraction. Because this test needs candidates to be conducted at home, parents become "invigilators". In order to ensure the effectiveness of the test, schools let parents receive "cloud" training before invigilation through online counseling and "A Letter to Parents" before the test. 15 minutes before each exam, parents remind students to empty their desks, prepare school supplies, mute electronic products such as mobile phones, prepare test papers, answer sheets and barcodes for the subject, and issue instructions such as "The exam is about to begin, please confirm that electronic products such as mobile phones are mute". After the exam is completed, submit the answer sheet by mail or sending pictures according to the requirements of middle school.

  Psychological micro-courses and expert lectures relieve stress and boost morale.

  In the past, the "countdown to the college entrance examination" hanging above the blackboard in the classroom can only "move into" the class groups of online platforms such as QQ and WeChat. Without the teacher around, the pressure and anxiety of many students have increased.

  Xi Huisuo, secretary of the Party Committee and president of Hebei Hengshui School, said that the college entrance examination is a big competition of comprehensive strength, which not only tests knowledge and ability, but also tests students’ psychological quality, will quality, behavior habits and physical health. In a special period, children are prone to anxiety at home, and even have some problems with their parents. At this time, psychological counseling becomes very important. To this end, Hengshui has arranged a special psychological teacher to record psychological micro-courses, and students can watch them on demand according to their own wishes.

The first place in Jiangsu liberal arts missed Qingbei. Do you understand the admission rules of the new college entrance examination?

  [Editor’s note] The candidates with the highest score in Jiangsu liberal arts are not allowed to go to Qingbei Nanda because their history subject level is B+. Many people said that they could not understand the current college entrance examination. In fact, in Jiangsu’s current "3+2" recruitment model, Tsinghua of Peking University has been asking for double A or above for many years. But this will be the last year for Jiangsu to use the old model. Jiangsu will implement the new college entrance examination plan next year. 澎湃 Mathematics course took Zhejiang, the first batch of reforms, as an example last year, sorting out the long examination course and 35 subject choices of the new college entrance examination. In a blink of an eye, Zhejiang sent out four new college entrance examination students. With minor adjustments and small patches, local reforms were rolled out one after another, and the reform ideas disassembled in this paper were basically continued.

  In our second and third year of high school, we may have experienced many exams and model exams, but the college entrance examination is only in June of the third year of high school, so it is also called "one exam will set you for life". However, in today’s high schools in Zhejiang, students of Grade Two begin to prepare for the academic proficiency test early, which may become the first record that affects college admission.

  The second year of high school started the college entrance examination, and it took two years to pass the "test"

  Du Yiming, 19, is a senior three student in a first-class key middle school in Zhejiang Province. In addition to the number of words, Du Yiming chose physics, chemistry and biology as college entrance examination subjects. His college entrance examination began in November of the last semester of Senior Two.There are more key exams, and "every time matters, you can’t relax every time".

  Du Yiming took part in the "first college entrance examination" of four subjects: biochemistry and foreign languages in November last year. On the first weekend of April this year, he will take part in the "second college entrance examination" for selected subjects. The results of the materialized students in these two exams will be included in the total score of the college entrance examination according to the grade assignment. By the time of the national college entrance examination in June, Du Yiming will face an exam beyond the number of languages. There is only one chance to get Chinese and math scores, and the foreign language scores will be included in the total score according to the actual test scores, based on the foreign language test results in November last year.

  When the national candidates finished the college entrance examination in early June, Du Yiming was greeted by the "Trinity" exam of Zhejiang University. For Zhejiang candidates, if they want to sprint to some top universities in China, such as Peking University and Tsinghua, it is best to take the "Trinity" exam which is put forward by these universities in mid-June. In the end, the results of this exam will be combined with the scores of six subjects in the college entrance examination and the scores of earlier academic level exams to form the admission transcripts in proportion. Such a "trinity" admission quota may account for more than 80% of the admission channels of these colleges and universities; If candidates intend to enter the above-mentioned colleges and universities solely by the results of the college entrance examination, it is not impossible, but it also means giving up many opportunities automatically.

  Du Yiming’s tense preparation schedule is not an isolated case. Compared with the traditional college entrance examination mode of "one exam determines life", the new college entrance examination reform in Zhejiang has undergone tremendous changes.

  To sum up, there are probably three new features:

  1. Cancel the division of arts and sciences, and use the new rule of "three subjects must be tested except the number of languages, and the other subjects should be selected from 7";

  2. Foreign languages and elective subjects are provided with 2 examination opportunities, and the highest score is included in the total score of the college entrance examination, and the elective subjects are graded according to the ranking;

  3. Not limited to the unified entrance examination, the "Trinity" enrollment scale of universities directly under the Ministry of Education in and outside the province has expanded.

  The road to the new college entrance examination is full of choices besides hard work.

  Option 1: Customize your own exam schedule.

  Every candidate has a dense examination schedule in his hand. Different from the traditional "one exam for life" model, each exam in the above table may affect the final admission.

  Do you want to participate in the "Trinity" enrollment? How many times do you need to take the exam? How many courses do you take each time? For these questions, candidates need to customize their own examination schedule according to their own situations and goals.

  If we take the recruitment path of the general college entrance examination, it will affect the admission of two rounds of elective examinations and the college entrance examination of three subjects other than languages. As for the academic examination, as long as we "pass the exam", it will do.

  If you take the "trinity" recruitment path, all the above exams will affect the admission: you need to get as many As possible A’s (accounting into the "trinity" total score) in the academic exam, take two rounds of elective exams and the college entrance examination outside the language number, as well as the "trinity" in-school test of your favorite university.

  At present, there are 57 colleges and universities participating in the "Trinity" enrollment in Zhejiang, including 49 colleges and universities in the province and 8 colleges and universities directly under the Ministry of Education. Tsinghua University, Peking University, Shanghai Jiaotong University, Fudan University, Zhejiang University and China University of Science and Technology all participate in the "Trinity" enrollment.

  According to the information released by Zhejiang Education Examinations Institute, there are 8,690 "Trinity" enrollment plans for colleges and universities in Zhejiang Province this year, and the "Trinity" enrollment brochures for colleges and universities outside the province and directly under the Ministry of Education have not yet been released, with 1,664 students last year. Since the enrollment plan for the general college entrance examination in 2019 has not been announced, if we refer to the 231,000 college entrance examination enrollment in 2018, the ratio of the two enrollment numbers is about 1:23, and the proportion of the "Trinity" in all enrollment can not be underestimated; It is even more important to occupy more than 80% of the enrollment in some colleges and universities.

  Option 2: 35 combinations of courses, which three subjects to take?

  After the reform of Zhejiang College Entrance Examination, seven subjects were arranged and combined, and 35 different ways of selecting subjects were derived.

  The Paper (www.thepaper.cn) found a general administrative class of "Chemistry+Biology" graduated from a first-class key middle school in Zhejiang Province in June 2018, and recorded the decision of 57 students in this class to choose subjects.

  By comparing the ranking of each student in six large-scale exams in high school for three years, we find that it is very reasonable.Students should first consider the dominant subjects when choosing subjects.. Hao Chenfei, a teacher of the school, said: "Even if there is more room for some subjects in the future, students still choose subjects with their own advantages."

  In this class, we found that eight students chose three subjects with the best grades in Grade One.

  Such new rules may help some candidates to "overtake in corners".

  We find out two all-round academic tyrants and two partial scientific tyrants in our class for comparison. The results of all-round academic tyrants in every subject in Grade One of Senior High School are in the top 20% of the year, and the total scores of seven subjects rank the highest. The scores of the subjects selected by the partial science tyrants are all in the first 20% of the year, but the other subjects are relatively backward.

  Let’s look back at the distribution of the scores of the all-round academic tyrants and the partial scientific tyrants in the first year of high school. The scores of these four students in the selected subjects are relatively close, but judging from the total scores of seven subjects, the all-round academic tyrants are completely ahead of the partial scientific tyrants:

  By choosing subjects, the partial science master got rid of the inferior subjects, narrowed the distance with the all-round learning master, and even surpassed the all-round learning master in the final ranking. According to the grading method, we convert the ranking percentage of the above four students in the six large-scale exams from Grade One to Grade Three into grading, and illustrate the performance curves of these students. If you only look at the two exams in senior three, you can’t even judge who is the all-round academic tyrant and who is the partial scientific tyrant.

  In this class, there are also students who do not choose the dominant subjects completely according to their personal rankings.

  The reason for this phenomenon may be that candidates consider choosing a major in the future. Li Zirui, a senior three student in this school, became interested in computer programming in his freshman year. In order to further his studies in computer science in the future, he "chose physics almost without hesitation when choosing a subject".

  Option 3: How to foster strengths and avoid weaknesses under the customized rules of colleges and universities?

  The new college entrance examination rules also provide colleges and universities withMore recruitment autonomy.

  On the one hand, unlike in the past when there were only two types of students in arts and sciences, there are more targeted requirements for students to choose examination subjects when enrolling students in various majors in colleges and universities. For example, Peking University’s astronomy and psychology majors require candidates to choose subjects that contain physics; The majors of finance and finance in Renmin University of China require candidates to choose subjects containing history or physics; Zhejiang University’s humanities experimental class is not limited to elective subjects.

  According to Zhejiang Education Examinations Institute, in 2019, 6.8% of the subjects required for the examination were one, 8.8% were two, 23.3% were three and 61.1% were unlimited. Compared with 2017, in 2019, some colleges and universities put forward more explicit requirements for the selected subjects for majors with clear training requirements and high correlation with the subjects studied in middle schools, while those with broader basic literacy requirements appropriately relaxed the scope of the selected subjects.

  On the other hand, the "Trinity" comprehensive evaluation enrollment channel has been widened. Colleges and universities can organize on-campus tests more independently, screen students and select the best candidates through written tests, interviews and physical tests.

  Take eight universities outside Zhejiang Province and universities directly under the Ministry of Education in 2018 as an example. The total number of students enrolled by these top universities in Zhejiang through the college entrance examination is 1,696 (including 1,618 from Zhejiang University), while the number of students enrolled through the "Trinity" is 1,664, which is close to 1:1 in overall scale.

  If Zhejiang University is stripped off, the number of people recruited by other top universities in China through the "trinity" comprehensive evaluation has far exceeded the enrollment of the college entrance examination. In other words, if you are a fresh graduate and want to be admitted to the above seven top universities, the safest plan is to participate in the "trinity" comprehensive evaluation enrollment of these schools; Otherwise, when the college entrance examination is filed, even if there is a very good college entrance examination result, the enrollment places of these top college entrance examinations are few and far between. Take last year’s enrollment plan as an example.Tsinghua University enrolled 8 students in Zhejiang through the college entrance examination and 105 students in Zhejiang through the Trinity. Peking University enrolled 23 students in Zhejiang through the college entrance examination and 85 students in Zhejiang through the Trinity.

  In addition to broadening the enrollment channels, colleges and universities also have greater initiative in the on-campus testing stage, and can screen candidates in multiple dimensions such as written test, interview and physical fitness test.

  Taking the written test as an example, in the "Trinity" comprehensive evaluation test of top universities in China, physics, as a "sharp weapon" for screening candidates, has become a compulsory subject for most candidates. Even if the candidate’s college entrance examination subject is not physics, he may be examined in the written test on campus. According to Tsinghua University’s "Trinity" Comprehensive Evaluation Admissions Guide for Zhejiang Province in 2018, in the on-campus test, 77.1% of the candidates were examined in physics during the written test.

  Peking University’s "Trinity" comprehensive evaluation is similar. Regarding the written test content of college tests, Peking University’s 2018 Zhejiang "Trinity" comprehensive evaluation enrollment brochure stipulates that there are five written test subjects, of which three subjects are required to be tested, and two are selected from the four subjects of "physics, history, chemistry and politics", requiring "physics".

  In 2014, Du Yubo, then Vice Minister of Education, used four "most" words to describe the reform of the new college entrance examination: "This examination enrollment system reform is the most comprehensive and systematic reform since the resumption of the college entrance examination, and it is the most important and complicated reform in the comprehensive education reform".

  In a blink of an eye, Zhejiang New College Entrance Examination has sent out two students. In 2019, senior high school students are about to sprint the college entrance examination in June and become the third graduates of the new college entrance examination. In the process of implementation, minor adjustments are still taking place in Zhejiang.

  No matter the front-line teachers and students or the education reform experts, there is no agreement on how to deal with this zero-sum game. In a broader sense, it remains to be seen where the college entrance examination reform in China will go.

  At the request of the interviewee, the teachers and students in this article are all pseudonyms.

[Network rumors] Beidaihe network rumors into the lottery station

In order to further improve the masses’ ability to identify rumors, consciously resist online rumors, and jointly safeguard the clearness of cyberspace, recently, the Network Information Office of Beidaihe District Committee entered the lottery station to carry out online rumor propaganda activities.

By distributing leaflets, answering questions on the spot, etc., the activity publicized the contents such as online rumors and online reports, and sent a "big meal" for the majority of lottery players, and encouraged lottery players to actively participate in reporting harmful information, resist online rumors, and consciously surf the Internet according to law, in a civilized way and rationally.
