What happened to the rural house, which is high in the west and low in the east?

A knife in the west is a taboo in geomantic omen, which is unfavorable to the hostess and even fatal. It's no problem to be higher in the east. Although we can't believe it blindly, some things can't be believed, and there are too many phenomena that science can't explain. Some things, such as China's traditional geomantic gossip, are effective only because they are some experiences or lessons summarized according to certain laws. It's not that feng shui fortune telling itself makes people get into trouble because of superstition, but because it's useless.
