Geomantic omen generally says twenty-four mountains, but why is there a saying of eight houses geomantic omen? What is hachi?

Eight houses are four houses in the east and west, and four lives in the east and west. The method comes from Bajiajing (recorded in Sikuquanshu), and its palm is definitely a wild horse jumping over a stream.

Many people who don't delve into the eight houses say that the eight houses method is not good. In fact, the big travel method, the bamboo festival method and all kinds of exorcism methods were borrowed from many schools later.
