Secondly, according to the picture you drew, it should be the opening of feng shui.
Open your mouth: the door is facing the stairs or elevator. This pattern is called evil spirits, and the wealth of the main family flows out. The cracking method is to set a screen behind the door to prevent the internal air from leaking out, or to place big-leaf plants such as rich trees and cash cows in the door.
I understand that the principle of this evil is that the road or corridor is facing the door. Because people often walk around and there are many people, all kinds of gases will have adverse effects on people over time. Therefore, you can also hang a curtain on the door and paste blessings such as safe entry and exit, lucky money and treasure. I hope it helps you.
