What does it mean that all religions belong to the world?

When Fuxi painted heaven and earth, this painting was Tai Chi, which also contained Yin and Yang. Fuxi painted the combination of yin and yang, forming the eight diagrams.

Eight diagrams symbolize eight natural phenomena: heaven, earth, thunder, wind, water, fire, mountains, so as to infer the changes of nature and society. It is believed that the interaction of Yin and Yang is the root of all things, and Gankun divination plays a particularly important role in the Eight Diagrams.
