After studying in Japan for five years, Mr. Chen Zungui returned to China on 1926, and successively served as a professor in Beijing Higher Women's Normal School, Department of Mathematics of National Beijing Normal University and Baoding Hebei Provincial Agricultural College. At the same time, he also works part-time at the Central Observatory, responsible for compiling almanac. 1928, the Institute of Astronomy of the National Academia Sinica was established in Zijinshan, Nanjing. Mr. Chen Zungui was hired as a full-time researcher of the institute and concurrently served as the director of mathematics discipline of the institute. So he officially entered the field of astronomy in China, and began his astronomical career for more than 60 years. 1955, Zhu Kezhen and Wu, two vice presidents of China Academy of Sciences, invited Mr. Chen Zungui from Nanjing to Beijing and entrusted him with the task of creating the first planetarium in China. The name "Planetarium" was put forward by Chen Zungui. In foreign countries, the unit with planetarium is called "Planetarium", which only plays a single role as an astronomical cinema. Considering the national conditions of China, Chen Zun said that astronomical science is relatively backward and people have little astronomical knowledge. Therefore, the planetarium should become a research and popularization unit, focusing on cultivating talents. The comrades of the planetarium construction group unanimously agreed with Chen Zungui. Therefore, the newly established "Beijing Planetarium" is centered on the Planetarium, equipped with astronomical observation stations, weather stations, astronomical exhibition halls and lecture halls, and has no physics laboratory and optical workshop (to prepare for the manufacture of astronomical teaching AIDS and telescopes in the past). After more than two years of construction, on September 29th, 1957, the first planetarium in New China, the Beijing Planetarium, was officially opened.
The establishment of Beijing Planetarium became a big news at home and abroad at that time, attracting thousands of tourists. Party and state leaders Liu Shaoqi, Zhou Enlai, Zhu De, Chen Yi, He Long, Guo Moruo and Zhu Kezhen visited the museum successively. Premier Zhou of president and the State Council gave important instructions to the development of the Planetarium, which greatly encouraged curator Chen Zungui and all the staff of the museum. At the end of 1956, Chen Zun led an astronomical delegation from China to visit the Soviet Planetarium in Moscow, Leningrad and Kiev. After the catastrophe of the Cultural Revolution, Mr. Chen Zungui's eye disease worsened and he became blind. However, he never lost his ambition. From the age of 70, he re-collected information and compiled the History of Astronomical Literature in China. In order to be accurate, after each manuscript is completed, it will be sent to Shanghai to ask Mr. Wang Quchang, a master of Chinese studies, to proofread ancient books, and the title of the book will also be ghostwritten by Mr. Wang Quchang. 1980 Mr. Chen Zungui is 79 years old. The first volume of the history of Chinese astronomy was published by Shanghai People's Publishing House. Then for nearly ten years, I stumbled, and it was not until the end of 1989 that four volumes were published. The book has 2300 pages and 1.7 thousand words, which is a masterpiece. The History of Astronomical Literature in China is a rare research masterpiece at home and abroad, and it is also a precious material in the cultural library of the motherland.
Mr. Chen Zungui is honest, cheerful and enthusiastic. Especially concerned about the development of young scientific and technological workers, concerned about the growth of young astronomy enthusiasts. His family often has guests, many of whom are graduate students and middle school students. He is also willing to accept people's advice and business guidance. Even if you are over eighty, it is not convenient to walk, but you always send your guests to the gate. The approachability, enthusiasm and courtesy of the older generation of scientists left a deep impression on the visitors. 1982, 82-year-old Chen Zungui applied to join the China Producers' Party and realized his lifelong dream. He said that in his lifetime, he must set a standard for himself to truly produce party member, and strive to make more contributions to the construction of the motherland. He feels that he has a lot of things to do. Write memoirs; Compile an astronomical dictionary; I have to write some research papers. Only by working hard day and night can we finish it. At the same time, he often went to the Beijing Planetarium, cared about the construction of the planetarium and taught young astronomers astronomical knowledge and work experience until his death.
