What is the mystery in the Book of Changes?

Fuxi, the legendary creator of gossip, has been deified. "Taiping Yulan" quoted "The Emperor's Genealogy" as saying that "Fuxi has a head and a snake body." The Book of Changes says that gossip is "river drawing, Luo writing, sage writing." This artificially adds a mysterious color to the Book of Changes.

I ching has the ability to predict the future.

The Book of Changes was originally produced and developed for people to predict their fate. "On the Cohesion of Yi" says, "Sages set up divination to observe images, and the connectors are vague, but the good and bad are clear." It also introduces the primitive and mysterious complicated way of calculating divination with yarrow. Perhaps not many people knew this divination method at that time, so it is necessary to introduce it. People always hope to be able to predict their future, but they can't do anything about it, so they pin their hopes on the mysterious God, and thus create the Book of Changes, which can tell people the confusion of the world and God's prophecy. The future is unknowable, and the prediction of the unknowable future beyond human power is of course mysterious. This is the fundamental reason for the mystery of the Book of Changes.

3. The Book of Changes has its own specific symbol system.

The mystery of the Book of Changes is that symbols are the main body of information transmission. Although people have endowed these symbols and their combinations with meaning, symbols can only be highly abstract, so the meaning of symbols must be vague. Vague and uncertain, when people look at it with reverence, they will feel unfathomable and mysterious. Mystery is an inevitable attribute of simple symbol system as a tool to convey complex information.
