What are the names of many areas in the sky divided by people?

1, ancient constellation division

Western constellations originated in Babylon, one of the four ancient civilizations. In the 2nd century A.D., Ptolemy, an ancient Greek astronomer, synthesized the astronomical achievements at that time and sorted out 48 constellations. Connect the main bright stars in the constellation with imaginary lines, imagine them as images of animals or characters, and give them appropriate names in combination with fairy tales. This is the origin of the constellation name.

In order to facilitate research, people divide the starry sky into several regions, which are called constellations. China has long divided the sky into three walls and twenty-eight nights. Historical records and official records are quite detailed.

Sanyuan is the three areas around the north celestial pole, namely Ziweiyuan, Taiweiyuan and Tianshiyuan.

Twenty-eight branches are located in 28 areas near the ecliptic and the white road, namely, seven branches in the east, seven branches in the south, seven branches in the west and seven branches in the north.
