What are the contents of Sanhe Feng Shui?

Kong Xuan is easy to spread secrets, as well as folk geomantic omen. I have read such books in our family, such as Sitting at a Simple Table, Fifty Sections of Geography and Feng Shui Po.

I'm not sure about ancient books, because the Three Rivers Feng Shui comes from the ancient traditional school of Feng Shui, and the knowledge of Three Rivers Feng Shui is very extensive, and it also involves strange things. The ancient books are incomplete and the mysterious house is full of secrets.
