Principal Yang Jinfeng's "Baijia Primary School Song"
Ho Na Ren Chao Ge Tu
"Why did something fall on the rocket when it was launched?" "The earth is round, I stand on the earth, why didn't I slide down?" This is a question raised by primary school student Fan Yize on May 12, 2021, when he gave a popular science lecture in Dalibaijia Village, Shaanxi Province, a village of Mongolian descendants.
He Naren Chaogetu, a young scientific and technological worker, would not have dreamed that there would be a village of Mongolian descendants in the eastern part of Guanzhong, and he would have a relationship with it when he grew up in the steppe of Inner Mongolia.
He Naren Chaogetu is a Mongolian ethnic group, "He" is his Han surname, and the Mongolian name "Naren Chaogetu" means sun-like enthusiasm and light, lively and sensitive, and full of vitality. As the name suggests, He Naren Chaogetu is a passionate and vigorous Mongolian youth, grew up in the Xing'an League Horqin Right Wing Front Banner, graduated from Nanjing University of Science and Technology with a master's degree, and is now engaged in scientific research of high-energy solid propellants in a research institute of aerospace chemistry in Hubei Province.
Popular Science Lecture Scenario 1
He Naren Chaogetu also had an exciting mission - as a Mongolian aerospace scientist, he was invited to the Baijia Primary School in the village of Mongolian descendants to teach a space science lesson to the children.
Communicate with Ho Na Ren Chao Ge Tu
When communicating with Ho NaRen ChaoGetu, he said: "Although I have participated in several aerospace science lectures and competitions, it is the first time to speak to primary and secondary school students. In the past, most of the audiences he talked about popular science were adults, and some of them had a certain professional background, and there was a chance to correct mistakes; to primary and secondary school students without any concept, they were still a little uneasy in their hearts, one was afraid that the children's partial questions and tricky questions were not in his professional field, and the answers could not affect the effect of the lectures; second, they were afraid that their lectures would mislead or bias the children. This kind of psychology and worry precisely reflects the good personality and scientific research literacy of Ho Na Ren Chao Getu who is rigorous and responsible and pursues perfection.
At 8:10 a.m., the science lecture officially began. Ho Naren Chaogetu broadcast a video of a news report on the Launch of the Core Module of the Tianhe by the Long March 5 carrier rocket on April 29. Taking this as a starting point, he told the children about the origin, naming and classification of the Long March rocket, which aroused great interest among the children.

He then used the example of "the feeling of weightlessness when riding a car through the arched bridge deck" to tell the children that they can fly when they are particularly fast. If you compare the earth to an arch bridge, when its speed is fast to a certain extent, it can become a satellite. The "speed" of being able to fly up , 7.9km/s , he told the children that it only takes 13 seconds to get from Baijia Elementary School to Xi'an, compared with 35 minutes by high-speed train and one and a half to two hours by bus. To reach the "speed of flight", a "rocket" is needed. As for how the "rocket" flies, he uses the analogy of "the balloon is exhausting backwards" to tell the children that the rocket also jets backwards. With the basic concepts, he explained to the child the basic structure of the rocket - boosters, core-level engines, fairings, escape towers... Wait a minute. To fly, the "rocket" needs a lot of fuel as a power, so the rocket that ordinary people see is very large, several stories high.
At the same time as "looking up at space", He Naren Chaogetu told his own growth experience: When he was in elementary school in 2003, he saw the news on TV about the landing of the "Shenzhou 5" spacecraft return module in Inner Mongolia, and he had the ideal of exploring spaceflight and dedicating himself to spaceflight. At that time, he attended only 7 students in the primary school, which was less than the students in Baijia Elementary School, and the conditions were difficult, but this did not affect his dream of spaceflight. He Naren Chaogetu told the children that with "dreams" there is hope in life, there are goals of hard work and struggle with hope, with goals, you will not feel that learning is hard, and if you pay, you will be rewarded, and it is possible to realize your dreams.
Later, He Naren Chaogetu talked about the practical significance of "spaceflight" for ordinary people: for example, navigation satellites have greatly improved the convenience and accuracy of mobile phone navigation. Whereas you used to go to unfamiliar places by asking for directions, now mobile phone navigation can easily take you to where you are looking. After that, the importance of meteorological satellites for weather forecasting was cited, the application of "fire extinguishing bombs" in high-rise building fire extinguishing, the application of "rain and hail bombs" in artificial rainfall and artificial intervention in "bad" weather, the protection of "airbags" for life safety, and the protection of "fall prevention devices" for the elderly...
One by one, the vivid examples around them stimulated the children's curiosity and curiosity, and one question after another related to spaceflight, space, earth, and satellites was raised by the children, and He Naren Chaogetu answered them one by one in a language that the children could understand.
The 45-minute course soon came to an end, the children were still unsatisfied, And Ho Na Ren ChaoGetu's "Aerospace" science popularization class sowed the seeds of "ideals" in the hearts of the children and ignited the "hope" in the hearts of the children...
Dedicated new media "Ju Da Li" Mr. Li Yuefeng
Dali Baijia Village, located in the "Shayuan" area west of the Yellow River, north of the Wei River, and south of the Luo River, accounts for more than 95% of the villagers with the surname Bai, and is a village of Mongolian descendants. The root origin of the bai surname can be traced back to the "Zima Rescue Khan" in the "History of the Yuan", Kong Wenguwa, who was recognized by Genghis Khan as "Qili" (relative), Muhua Li, who was named Zuo Wanhu and "King of Taishi" by Genghis Khan, proposed to build the capital "Youyan" (present-day Beijing) Kublai Khan's "Lianyi" Badulu, Yuan Shizu's right chancellor An Tong... The descendants of the Mongols in Baijia Village changed their surname to "Bai", which began with the second son of Emperor Yuanyingzong's right-hand man "Baizhu", Inanashuoli (given the name Dulin Tiemu'er by Emperor Wenzong of Yuanwen), dating from the early years of Ming Hongwu, taken from the first transliteration of the Mongolian name of "Baizhu". This information related to mongolian history and culture made Ho Naren Chaogetu feel that the significance of this popular science lecture was unusual.

Baijia Village is also the ancestor of the Jingchu people - the site of the fiefdom of gaoyang city, the head of the Five Emperors, professor Zhou Hongwei, doctoral supervisor of Shaanxi Normal University, the paper "New Cai Chujian and Chudu Migration Problem Re-understanding", which has professional research and interpretation, published in 2009 in the "Historiography of Peking University". When colleague He Naren Chaogetu from Jingchu Dadi learned of this news, he showed great interest, saying that he would consult Professor Zhou's research papers after he returned, and would tell more people about this news, and would come to Baijia Village at the right time to visit the "Gaoyang City Ruins" to make up for this regret.
The students who participated in this aerospace science popularization lecture were representatives of 26 students in grades 1-5 of Baijia Primary School and 30 students of Guanchi Junior High School. The activity was strongly supported by the relevant leaders of the Dali County Education Bureau, Principal Ma Weimin of Guanchi Central School, Bai Juping, Secretary of the Party Branch of Baijia Village, Village Chief Bai Juping, Deputy Village Chief Bai Xinxin, and Principal Yang Jinfeng of Baijia Primary School.
