See you at 8 o'clock in the news, a little more insight. Meet you on time every morning at 8 o'clock in the morning and look out into the bigger world.
The first lesson of "Tiangong Classroom" was successfully concluded on the afternoon of December 9th! The students visited our "Tiangong Homeland" in the form of live broadcast and made interesting space experiments with the astronauts. What is the status of the lecture site? How are space experiments conducted?
What are the "courses" in Tiangong Classroom? According to the Ministry of Education, the teaching activities will be carried out in the interactive way of heaven and earth, with the main ground classroom set up in the China Science and Technology Museum, and the ground sub-classroom in Nanning, Guangxi, Wenchuan, Sichuan, Hong Kong and Macao. At that time, the three astronauts will introduce and display the working and living scenes of the Chinese space station in orbit, demonstrate the phenomenon of cytology experiments, object movement, liquid surface tension and other phenomena in the microgravity environment, and communicate with the ground classroom in real time to disseminate manned spaceflight knowledge and stimulate the interest of the majority of young people in science.

What is the highlight of this "Tiangong Classroom"?
Highlight 1: Secret weapon "Penguin Suit": Astronaut Zhai Zhigang said that weightlessness has an impact on our cardiovascular system, has an impact on our bones, and has an impact on our muscles. In order to prevent weightlessness from causing our muscles to atrophy, in addition to the treadmill, bicycles, and pullers, there is also a secret weapon in the space station. These are the two adjustment rings of the chest pull strap to adjust the elastic pull of the chest. Through these pull straps to bind the human body tightly, so that the muscles can maintain a certain tension for a long time, you can effectively prevent weightlessness to bring us muscle atrophy, the name of this set of clothes is called penguin suit.
Highlight 2: Buoyancy disappearance experiment: The first lesson of "Tiangong Classroom" Wang Yaping also did an experiment of buoyancy disappearance. In space, ping-pong balls do not float on the surface of the water like they do on the ground, but stay in the water. Astronaut Wang Yaping introduced that this is completely different from the phenomenon on the ground, this is because buoyancy is generated with gravity, and buoyancy almost disappears in the weightless environment of space, so ping-pong balls cannot float up like on the ground.
Highlight 3: Effervescent film experiment: In the first lesson of today's (9th) "Tiangong Classroom", space teacher Wang Yaping did such an experiment. I saw that the effervescent tablets were constantly bubbling in the water ball, but in the weightless environment, the bubbles continued to be generated, but they did not leave the water ball. As the bubbles continue to increase, the water balloon gradually becomes a "bubble ball" full of joy, and it produces a burst of aroma. Read the full >>>
What is the significance of this space lesson? Wang Yaping said that space teaching has created a new model and new method of science popularization education and primary and secondary education in our country, and it can be said that it is by far the world's widest audience, the largest scale, and the longest teaching time of a live science education live broadcast activity.
Eight years ago, Wang Yaping stood on the world's highest podium, using the special microgravity environment in space, and conducted 5 scientific experiments such as spring mass measurement, pendulum motion, gyro motion, and making water film water balloons for 40 minutes. 60 million students from 80,000 schools across the country watched the live broadcast synchronously, which played a very good role and was of great significance to young people's interest in advocating science and exploring the mysteries of space.

After 8 years to open the lecture, the famous astronaut Huang Zhicheng said that this space lecture is somewhat different from the last space lecture, the core module of the "Tiangong" space station is much larger and more modern than the Tiangong-1 target vehicle, so it can be more convenient and more exciting to demonstrate space experiments and space life. At the same time, the performance of China's measurement and control communication system has been greatly improved, relying on the broadband provided by the Tianlian-1 relay satellite constellation, which can transmit the high-definition video of space teaching back to the ground more smoothly. In addition, in terms of the content of the lecture, there are not only physics experiments, but also biological experiments, which can broaden the horizons of young people. Read the full >>>
On December 9, the Beijing Secondary School Entrance Examination Sports Reform Plan was officially announced.

Have you ever brushed up on the "Siping Police Incident"? It is the official Douyin number of the Siping Municipal Public Security Bureau in Jilin Province, and has produced 204 short videos, mostly sitcoms. Up to now, the number of fans of "Siping Police" has exceeded 16 million, and the movie starring the "Popular Law Trio" was also broadcast in October this year.
In these plots that take telecommunications fraud, drunk driving, impersonation of public servants and other illegal and criminal activities as counterexamples, auxiliary police officer Dong Zheng and his partners Zhang Hao and Wu Erwo played by the "stupid thief" fight wits and courage, using paragraphs to popularize the law, which is called "the most skinny government affairs number" by netizens.
The original "Siping Police Incident" was actually not satisfactory. In May 2018, when the "Siping Police" account was first opened, there were only 45 fans, many of whom were "begged" by Dong Zheng. Dong Zheng works in the Press and Publicity Department, and the mainstream media he originally contacted were television, radio, newspapers and WeChat public accounts, but short videos have already shown signs of invading life. Compared with the text, Dong Zheng feels that the video is more flexible and intuitive, the visual impact and interactivity are strong, and the audience is also wide. After some analysis, both Dong Zheng and Sun Xuejun, the director of the department, believed that "it can be done."
Filming a popular law short drama actually stems from dong Zheng's emotions that have been coiled up in his heart for many years. "Every year, public security police officers die in the line of duty." In 2015, there were 438 and in 2016 it was 362, "especially in those two years, an average of one a day." "For Dong Zheng, this is by no means just a number. His father, also a police officer, suffered a heart attack while on duty and died in the line of duty. At the same time, Dong Zheng found that many conflicts are temporary intentions, but also stem from some people's weak legal awareness, "If everyone's legal awareness is improved, think about the consequences before committing a crime, a knife may be indefinite, can not be committed, may dispel the idea." A crime is thus eliminated, and the police are less dangerous. ”
Looking back at the "out of the circle" road, Sun Xuejun, director of the Information and Propaganda Department of the Political Department of the Siping Municipal Public Security Bureau, said, "It is not accidental because the team really does things in a down-to-earth manner; it is accidental because 2018 is the 'first year of government affairs vibrato', and in the great trend of the times, we are fortunate to be among the forefront."

On December 8, local time, Olaf Scholz, the candidate for the german Social Democratic Party for the presidency, was officially elected as The German Chancellor. What impact will Scholz's inauguration have on Sino-German relations? Will Sino-German relations still be the same as in Merkel's time?
Scholz and Merkel belong to two political parties, and the political spectrum is not the same, and the Scholz era is certainly not the same as the Merkel era. However, from the perspective of Scholz's personal style and diplomatic stance, he is very similar to Merkel in many places, and even called the "male version of Merkel". During Merkel's 16 years in power, coalition governments were formed several times. Within the framework of the coalition government, Scholz twice entered Merkel's cabinet and held important positions.
Before Merkel's government came to power, Scholz's Social Democratic Party had been pursuing a reform plan called the 2010 Platform, including reducing pensions, reducing unemployment support, and eliminating some programs in universal health insurance, which risked social unrest. But Scholz's flexible employment policy under his presidency has allowed Germany to avoid large-scale layoffs and helped Merkel strengthen her voice in the EUROPEAN Union.
Merkel received widespread praise before leaving office, in part because of her restrained personal style. At this point, Scholz was also very similar to her. According to media reports, when Scholz was the president of the Social Democratic Party in Hamburg, he and his colleagues posted an A4 piece of paper in front of the TV set with the words "Scholz's Law", the first of which was "We never get angry, we never hysterical". Scholz himself has said that hard work is more important than rhetoric. But Scholz is also very good at taking advantage of the situation. Merkel's popularity peaked before leaving office, and Scholz always made himself her successor during the campaign.
After Scholz became Chancellor of Germany, one of the common concerns was whether Sino-German relations could remain as smooth as they were in Merkel's time. German media recently revealed that Scholz had previously sent a message to the Chinese side through EU Council President Michel, expressing the hope to continue Merkel's "pragmatic" china route. In fact, maintaining smooth Sino-German relations like the Ones in Merkel's time is not only a plus for Scholz, but also more conducive to leading the new government to solve many of the challenges facing Germany.

In December, the drama series "Wind Rises Luoyang" and the movie "Antiques Bureau Central Bureau" adapted from Ma Boyong's novel have met with the audience. Ma Boyong's name has also been frequently mentioned by the public recently. What kind of writer is he? What is his thought on the film adaptation of the novel?
Ma Boyong continued the fireworks in his novels to the latest two works, especially "The Wind Rises luoyang". For "foodie" Ma Boyong, in order to write about the fireworks of a city, field research is a must, and only by going to the field can you feel the atmosphere. Xi'an and Luoyang are both one of his favorite cities to visit, and it is also a pleasure to visit.
As a full-time writer, Ma Boyong is very self-disciplined, never stays up late, sleeps at eleven o'clock at night, gets up at 6:30 in the morning, maintains a good life schedule and creative passion, likes to go to noisy places such as bookstores and cafes to write, continuous input, reading, in his view, writers must be miscellaneous, three teachings and nine streams know a little, can not be refined, but must be Bo.
Although many of his novels have been adapted into film and television works, Ma Boyong basically did not participate in the screenwriting work, and he was very separate from the two identities of writer and screenwriter. "If you can write a novel, you don't necessarily write a screenplay, and vice versa." In the face of traffic or IP, he does not want to be wrapped up in the market, "not what is hot in the market, to follow the trend to write what, but to write what they are good at, and look forward to the recognition of others." ”
On the issue of whether the text is suitable for adaptation and film, Ma Boyong believes that the most critical reason for whether a work is suitable for adaptation and film is whether it can provide a resonance to the reader. Maybe it's the resonance of emotion, maybe it's the resonance of experience, maybe it's the resonance of feelings, and when this sense of connection is established, then whether it's a novel, a movie, a TV series, a play or an animation, it will be successful.
