All the characters in the Water Margin have a constellation, such as Tian Fangxing. Is this an ancient constellation in China? Seek an explanation

Dude, it's not a constellation, it's a star. The earliest statement originated from Taoism. In the Romance of Gods and Demons written by Xu in the Ming Dynasty, the old gentleman systematically sorted out and perfected it, and formed a complete immortal appellation system. One * * *, there are 365 positive gods, including 36 highest days and 72 lowest nights in Shuihu, which belong to the highest day system or the highest night system, and there are also 28. There are historical or legendary figures corresponding to it. Although there are corresponding figures or legends in the constellation, the stars do not have the function of dividing people. In fact, the role of the constellation is similar to that of the zodiac.
