The Origin and Development of the Book of Changes

Zhouyi: It is not the Book of Changes, but is composed of the Book of Changes and the Book of Changes. The Book of Changes consists of three parts: First, Fuxi began with gossip, and there were no words at that time, so gossip. Second, Zhou Wenwang and his son inherited Fuxi's Eight Diagrams, and eighty-eight overlapping gave birth to sixty-four hexagrams. Zhou Wenwang and his son believed that the sixty-four hexagrams contained everything in the universe, and each hexagram had its own writing.
