What are the feng shui taboos on the corridor background wall?

The background wall can't be placed on the financial position. The owner of the financial position is quiet and stable, while the TV set is noisy. In addition, the background wall should not face the window, nor should it be on the wall where the window is opened. The living room is in the east, and the background wall should be dominated by yellow; The background wall of the living room facing south should be mainly white; The background wall of the living room facing west should be mainly green; The background wall of the living room facing north should be mainly red. In addition, the southeast direction should be dominated by yellow; The main color in the southwest direction should be blue; The main color of the northwest living room should be green; The main color of the northeast living room should be blue. The shape of the background wall should avoid sharp corners and prominent design. Try not to divide the background wall into meaningless clutter. I hope my answer is useful to you.
