The local folk superstition in China believes that houses facing east and west are full of vitality in geomantic omen, and the layout of the hall in the northwest will further promote this vitality and make the family's fate better. But all of the above are superstitions and have no scientific basis.
Sitting east facing west is a concept of ancient geomantic omen in China, and it is the crystallization of the wisdom of ancient working people. For people, it means looking west. For architecture: it is to open a door or window facing west. In short, it is "back to the East". Simply put: sitting east facing west is the main lighting surface of the house.
