What contents of Feng Shui are derived from Zhouyi? Is Zhouyi the Book of Changes? Or the relationship between tolerance and being tolerated?

Different schools of Feng Shui have different contents. Generally speaking, the orientation comes from Yi, and the five elements come from Yi. The content of other schools is different from that of Yi.

Generally speaking, I ching is not I ching. There are three books of changes, and one is handed down from generation to generation, called the Book of Changes. That is, the Book of Changes contains the Book of Changes.
