Brief introduction to the content of Heluo rational number

This book was not published at first, and there was no text. Zhu Zhen, a Yi-ology scholar in the Song Dynasty, edited the Book of Changes in Han Dynasty in Britain: "Chen Tuan planted seeds, wood shows, Li Zhicai and only then did it spread to Shao Yong." Shao Kangjie made an in-depth study on its causes and quantity, so as to carry it forward and spread it to future generations. It is this book that makes Shao Kangjie a master of Neo-Confucianism, a master of geomantic omen and the ancestor of divination.
