The origin of Ziwei fighting

According to legend, the book of Wei Zidou was invented by Chen Tuan (Chen Xiyi), an important Taoist figure in the Northern Song Dynasty. Wei Zi Dou Shu, formerly known as "Eighteen Flying Stars", came into being a little later than the five-star technique, and was influenced by Indian astrology at the same time as Zi Ping (eight characters and four pillars). Compared with the eight characters, there are far fewer works about the number of fights in the past dynasties. Due to the lack of information, the source and inheritance of the number of fights are not clear.
