I am suitable for living in houses facing north and south, and now they are all commercial houses. I want to ask my teacher.

In geomantic omen, the sitting direction of residential buildings is based on the direction of the main entrance of residential areas, and the opposite direction is the sitting side. If there are multiple doors in the community, take the door with the largest traffic of vehicles and pedestrians as the direction. The unit door and the entrance door are actually just air ports, that is, air passages. Therefore, the orientation of the house is based on the main door, not the porch and unit door.
