Masters, can I sit on the back wall (east) of the east-west or northeast-southwest residential building and open the window separately?

If you have to be superstitious, this should also be decided according to your horoscope, not whether this direction is suitable for all people in the world, don't you think? When you just want to open the window, you can open it in any direction, but since you believe in ghosts and gods, many things depend on the eight characters. The nonsense of the constellation is that if you are an Aquarius, then Aquarius people all over the world have the same temper and personality, but they look exactly the same. In short, I don't know what benefits superstition has brought you. Take it yourself.
