The Book of Changes has little to do with Taoism and Taoist thoughts, but the Book of Changes has absorbed a lot of Taoist thoughts. The connection between Zhouyi and Confucianism is not subtle, but huge and direct. First of all, the value orientation and argumentation methods of Zhouyi and Laozi are different. In the mode of cosmology, Yi Zhuan said that "Tai Chi is easy to occur, that is, two instruments give birth to four images, and four images give birth to eight diagrams". Laozi's Taoist cosmology model is "Tao gives birth to one, destiny gives birth to two, destiny gives birth to three, and everything is negative while holding Yang, and rushing to think that it is peace". Let me remind you that the previous "two instruments" refer to "yin and yang" or "heaven and earth", but this yin and yang is a concrete yin and yang; The latter refers to yin and yang, and things are both opposite and unified inside.

Secondly, in terms of value orientation, both Laozi and Zhouyi think that everything in the world is in an endless change, but Laozi thinks that "if you want to change, why should you change", while Yi Zhuan thinks that "only change is bound to change"? What do you mean? Yi Zhuan is facing the globalization of the universe and the significance of changes in the universe, and Lao Tzu is right. According to Yi Zhuan, the expansion of the universe is a process of continuous enrichment and growth from the origin of everything, which is commendable. And Lao Tzu also thinks that this is a process that is constantly plagued by contradictions and opposites, dismembered and degraded, so Lao Tzu gives priority to returning to the truth and singleness. Different theoretical bases have different value orientations. The only certainty is that the Book of Changes adopted some viewpoints of Laozi in the process of interpreting the Book of Changes. The only thing that can directly connect Taoism with Zhouyi is metaphysics in Wei and Jin Dynasties. During the Wei and Jin Dynasties, Laozi, Zhuangzi and Zhouyi were collectively called San Xuan. I don't know much about how scholars in Wei and Jin Dynasties chose Zhouyi. The only thing that is clear is the Book of Changes written by Wang Bi, whose value orientation is inconsistent with the Book of Changes and the Book of Changes. In addition to Taoism, Ye Fan said that it "takes Yin and Yang as its home", indicating that it has nothing to do with Zhouyi.
