The Eight Diagrams of Zhouyi was first created by the Book of Hutuluo, which was created by Fuxi Renshi. Innate gossip used the combination of yin and yang to illustrate the eight most primitive substances in heaven and earth. The acquired gossip comes from Zhou Wenwang, and its acquired gossip is just different from Fuxi's innate gossip. Its meaning remains unchanged. Until Confucius founded Confucianism, Zhou Wenwang's Book of Changes was included as a Confucian classic (that is, a Confucian textbook). In the Han Dynasty, Taoism created countless tricks from Yin and Yang, Eight Diagrams and Five Elements in the Book of Changes.
Most of Zhouyi's lectures are about the philosophy of life and the relationship between man and nature. Although the relationship between man and nature is the theme of Zhouyi's philosophy, the purpose of Zhouyi's discussion on the relationship between man and nature is to establish principles for dealing with people. Zhouyi believes that the first priority for people to get along with the world is to find their own place, and "being upright" is the first magic weapon for dealing with people. According to Zhouyi, everything in the world has its place, and people are no exception. Everyone should find his proper place in the world. If so, the world will be orderly and there will be no disasters. The same is true for a home, an enterprise and a group.
