What is the relationship between the Book of Changes and divination?

There are many ways to calculate hexagrams in the Book of Changes, such as copper coin method, big hexagrams method, fire bead forest method, etc ... But at present, domestic academic circles seem to only admit that the big hexagrams method is an authentic professional method, because it is mentioned in Cohesions Biography. However, there are many controversies about Dayan Law itself. I just give you a brief introduction. If you want to know, you can go online and look at related things.

As for how to communicate with people, you have to look at hexagrams, such as "Don't use hidden dragons". For example, if you occupy this place, you have to wait for the opportunity even if you have the ability.

You have doubts now, maybe you don't know divination. However, it is still possible to calculate divination. Xunzi said, "Those who will change will not take it."
