What is Zhouyi?

China's ancient works. Zhouyi is not only a book of divination, but also a book of self-cultivation through divination. Every hexagram is a fork in the road of practice. People are wrong and the world is wrong. If a person is ill, his career is ruined. Zhouyi is not so much a divination as a record of various diseases of the human body. The existence of Yijing supplements the diseases of Huangdi's Neijing. If the meridians of the human body are not functioning normally, there will be disaster.
