The Book of Changes is a product of ancient civilization and a philosophical work with a high degree of integration of natural science and social science in China. The Book of Changes is divided into three parts, Lianshan and Guizang in the era of Emperor Wu of the Han Dynasty, and Zhouyi in the Qin and Han Dynasties, which are collectively called "three changes" (the other said that all three books were written in ancient times). In ancient times, people set up astronomical phenomena, observed astronomical phenomena, gave time, created calendars and changed books. Civilization has begun.

Zhouyi is an ancient philosophical work of China, which demonstrates and describes the operating law of things based on the dualism of Yin and Yang. It classifies the characters of all things in the world and heavenly stems and earthly branches's Five Elements Theory, even accurate enough to predict the future development of things. Some people directly refer to the Book of Changes as the Book of Changes. There are eight diagrams in Zhouyi: Gangua, Kungua, Zhengua, Gengua, Ligua, Kangua, Dugua and Haigua.
