What about the corner between the door and the wall of the commercial housing room?

This is the knowledge of Feng Shui. According to geomantic omen, it is no problem to face the inner corner, while the outer corner is a symbol of blade and division, which leads to family discord. If you believe in Feng Shui, I suggest you find a designer to design it for you. If you believe it, you can also find a feng shui master to show you.
