What kind of mysterious Feng Shui book is suitable for self-study?

Some geomantic omen in the market cannot be people-oriented, which is obviously wrong.

Now there are some geomantic omen, such as four lives in the east and west and flying stars in the sky. They simply divide people into several categories to regulate geomantic omen, which seems very simple and easy to learn, but in fact they still fail to take people as the foundation.

Feng Shui is people-oriented, and Feng Shui is only for people. To learn feng shui well, you must learn the four pillars first, so I recommend that you look at the four pillars to predict the true way, which is suitable for self-study, and books are the foundation.
