What is the standard of geomantic omen in residential quarters?

If you are looking at feng shui, you should take the entrance of your house as the sitting direction of the whole house.

If you only have one house, the entrance door of this house shall prevail; If you are the owner of the whole building, the entrance door of this building shall prevail.

The door is the air inlet of the whole room. People who come in and out every day will open it and air will enter. The window is the air outlet of the room. Windows can't be used as a standard for sitting, but the buyer's direction is the direction of lighting, which is not a concept with Feng Shui.

I hope it helps you.
