Extended data

In ancient times, astronomy and astrology were a family:

Observing the sky and stars, the ancients not only hoped to know the alternation and change of seasons to determine the date of sowing, but also hoped to predict human floods, droughts, storms and military events by divining the stars.

At this time, "calendar" and "astrology" are mixed together and cannot be completely separated. For a long time in human history, astronomers and astrologers were once the same person, whether in the East or the West.

Gander, an astronomer in China during the Warring States Period, wrote a book Astronomical Astrology, and Zhang Heng and Li and his party in the history of China were also big stars. Ptolemy, Tycho, Kepler and other great astronomers in ancient western countries were also great astrologers. At that time, there was no boundary between astronomy and astrology.
