What's the difference between the Book of Changes and silk books?

One: Silk books are older than popular books. Two: Sixty-four hexagrams in the silk script are arranged in the order of eight classics, and the upper body and lower body overlap in a certain gossip order to form sixty-four hexagrams. The upper body is the palace divination, and the pure divination comes first. Three, the sixty-four hexagrams in the silk book Yi are different from Tong Tong's Yi, and there are two names that may be related to Gui Zang Yi. Four: Silk script is not an innate and acquired gossip preface, but a Zhongtian gossip preface, which is written for the study of Yi and has strong preconceptions, not for Confucianism. This is the most obvious difference. Of course, there are other differences, but not many people can easily read silk books, and not many researchers. Little-known mysteries need experts to uncover!
