What does Zhouyi mean?

The Book of Changes is the Book of Changes. The Book of Changes uses a unique symbol system, in which three groups of Yang "-"(a long horizontal line) and Yin "-"(two short horizontal lines) overlap to form eight diagrams, and six groups overlap to form sixty-four hexagrams.

Eight diagrams symbolize heaven, earth, water, fire, wind, thunder, mountains, and the characteristics of these eight things, and with the above characteristics, we can take analogy as everything.

The arrangement order of the sixty-four hexagrams in the Book of Changes is by no means random, but symbolizes the development process of things, and the hexagrams of each hexagram also have rich meanings.
