Please recommend some easy-to-learn books, which should be simple, detailed, illustrated, geomantic omen, divination and analysis.

You can read Li Juming's books. This man is a master of metaphysics. It is characterized by popularity and simplicity.

If you read anything like the original book of changes, including those written by the mainland, you will get bored after reading it for more than ten minutes.

These things are basically pondered by basic people, or studied by specialized scholars or students.

Regarding the mystery of the Book of Changes, Mr. Ceng Shiqiang's theory is basically Yi School, which talks about some principles of treating people with things.

If you look at Li Juming's, you will find it very interesting, that is, fortune telling and divination.

I suggest reading the introductions of Ceng Shiqiang and Li Juming.
