Houses in rural areas all face east rather than west.

In geomantic omen, the east is not connected with the west, and the west is less than one π. There are green dragons in the east and white tigers in the west. Not afraid of the blue dragon, but afraid of the white tiger probe. It means: the East is a green dragon and a lucky god. The west is a white tiger and a fierce god. The east is higher, and the west is definitely lower than the house. So everything can be answered.
