What do you mean, those who know the easy don't take advantage, and those who know the easy don't predict?

Those who know the I ching do not take it, and those who are good at it do not anticipate it. The meaning of this sentence is that people who really understand the Book of Changes will not divine for themselves or others, because the Book of Changes is not a book of divination, it is all-encompassing, and it talks about the basic laws and principles of the world. Knowing these laws and principles, I naturally won't do things like divination. This sentence tells us that it is very important to learn and understand the basic laws and principles of things, because only by truly understanding these laws and principles can we better cope with various situations in life and make more wise decisions. At the same time, it also reminds us not to be overly superstitious about divination and prediction, but to seek solutions to problems in practical actions.
