My upstairs door faces downstairs, okay?
The entrance door is facing the corridor and going down the stairs, which is the worst, because the airflow is the most unstable, and it leads to the loss of yang and the exuberance of yin, especially at night. In this very bad situation, five emperors' money is the most suitable, but ordinary five emperors' money can cope with the situation that the door faces the corridor or stairs at most, and if it goes down, you have to choose five emperors' money with particularly strong evil spirits. This kind of money contains Taoist artifacts and its structure is asymmetric. The stronger the dark evil spirits are, the more feng shui effect they can have. This is the layout of my previous decorator.
