Choose the floor according to the eight characters

You can't choose a floor with eight characters. This is a wrong idea. Combined with the specific mountain direction of the doorway of a building on your floor, you can determine Long Yuan after looking at the mountain to see if the basement is enough. After that, you can put it in the floor with a flying star. First of all, the geomantic omen in the Universiade, and then you can judge whether this building is a house of fortune by looking at the direction of the flying stars. The direction of the mountains here is not simply southeast and northwest, but is oriented by a compass.
