Who the hell is Chen Zhuo?

What period does it refer to?

If it is ancient, there are two.

1. Historical figures (Three Kingdoms)

Wu people in the Three Kingdoms period. Born in the 1930s; Died in the 1920s. Astronomers. When Chen Zhuo was young and middle-aged, he was appointed Taishiling of the State of Wu. He is good at astrology and proficient in astronomical astrology. He and Wang Fan, an astronomer of the State of Wu, wrote Huntian Shuo at the same time or later, and began to collect and summarize three popular astrologers at that time, Gan, Shi and Hsien Wu. After the destruction of Wu in 280 AD, Chen Zhuo entered Luoyang from Wudu Jianye (now Nanjing) and served as the official of the State of Jin. During this period, he drew an all-sky star map, covering three star officials, and wrote two parts: Zhan and Zan. He also wrote Tian Wen Zhan Ji 10, Fang Si Su Zhan, Wu Xing Zhan 1 0, Shiwan Jing 7 and Tian Guan Xing Zhan 10. At the beginning of the 4th century, Chen Zhuo had left the position of Taishiling, but he still took part in the occupation of the Royal Planetarium. In 3 16 AD, the Western Jin Dynasty perished and Chen Zhuo returned to Jiangdong. In 3 17, Jiankang (now Nanjing), the capital of the Eastern Jin Dynasty, participated in the establishment of Si Marui in Yuan Di and changed its name to Taishiling. Since then, there has been no record of other activities in the historical records. The most important work of Chen Zhuo's life is to synthesize the star officials determined by the three astronomical schools of Gan, Shi and Wu Xian, which originated in the Warring States or Qin and Han Dynasties, and form a relatively complete all-star official system, with 283 officials and 1464 stars. As the original work has been lost, Chen Zhuo's works are mainly based on the works of later generations, mainly including the Dunhuang manuscripts "Three Star Classics" and "Xuanxiang Poems", the book of Jin "Tianwenzhi" and "Kaiyuan Zhan Jing", and Sui Shu in Tang Dynasty. According to the analysis of these materials, in the all-star official system set up in Chen Zhuo, there are 93 Chinese and foreign officials in history, 627 stars, Gan officials 1 18, 5 immortals1,44 immortals, and 65434 stars in 28 nights. (Because of the different original data, the number of stars listed by each researcher is slightly different. The research shows that the general steps of Chen Zhuo's three stars in the Catalogue are: first, based on Twenty-eight Nights, then removing the repetition of the three stars of Shi, Gan and Wu, and adding their differences, the repetition of the three stars of Shi, Gan and Wu basically adopts the principle of stone first, twenty second and Wu second. The number of all-star official names summed up by Chen Zhuo has always been the standard for future generations to make star maps and images. According to records, Qian Lezhi of Liu and Song Dynasties cast Hunxiang twice in the 13th year of Yuanjia (A.D. 436) and 17th year of Yuanjia (A.D. 440), both of which used the figure set by Chen Zhuo to distinguish three stars with three different colors. Yu Jicai and others in Sui Dynasty took this image as the basis and drew a cover map with reference to various star maps. At the end of the 7th century and the beginning of the 8th century, another scholar in the Tang Dynasty, Wang Ximing, wrote the Song of Ascending to Heaven, which introduced the 283 official stars and 1464 stars summarized by Chen Zhuo in seven words and one sentence, and creatively divided the whole sky into 3 1 region, that is, the zoning method of three walls and 28 nights spread from later generations. This zoning method has been the basis of China's observation of the stars until modern times. Chen Zhuo's all-star official system has been used for 1000 years.
