The building is east-west, and the suites upstairs and downstairs face different directions. How is the geomantic omen oriented, the direction of the building or the direction of entering the door?

First look at the direction of the gate. Many people don't know the knowledge of this orientation, and they all take the window as the orientation. This is a great mistake. The first door that any door must enter is azimuth. If you are the owner, it means that the whole building is your own, so you should do a good job in positioning the whole building in Xiamen. If you are one of the units, there will be the first entrance of a single-layer unit as the orientation.
