How did China people know the ancient astronomical phenomena?

The ancient Chinese nation also created its own star division system. In order to know the stars and observe the sky, people give each group of stars a name. Such a group of stars are called star officials.

Each star officer contains a number of stars ranging from one to dozens, and the scope of the sky area is also different. According to preliminary statistics, there are about 38 star officials recorded in ancient books in pre-Qin period.

In order to know the stars and study celestial bodies, ancient people artificially divided the starry sky into several regions long ago. China called it the Star Officer and the West called it the Constellation. In ancient China, the sky was divided into three walls and twenty-eight lodgings, and the earliest complete written record can be found in Historical Records Tianguanshu.

Gan De, Shi Shen and Wu Xian in the Spring and Autumn Period and the Warring States Period. Each has established its own star officer system. When he arrived in the Three Kingdoms, Master Wu ordered Chen Zhuo to compile a catalogue of 1464 for 283 officials and draw a star map.

During the Jin, Sui and Tang Dynasties, China's star division system became mature. Since then, it has been used for thousands of years, and the most important star officials are Sanyuan and Erbasu.
