1. Airflow collision between the front door and the bedroom door.
There are two kinds of qi mentioned in geomantic omen, one is the terrestrial qi, and the other is the good or bad luck of flying stars. The way of gas entry is mainly through doors and windows. The air in the front door comes in through the road outside the door, and the air in the bedroom comes in through the hall, which should be the place where the air is gathered. If the air from the front door can't gather in the hall, the consequence is that the house will fail.
The bedroom is a very private place.
If the bedroom door faces south, it is not good for women aged 15 to 30, especially those with evil peach blossoms. To resolve this evil, put a screen between the door and the bedroom door.
The master bedroom has high privacy. If the window is too low, it will become a privacy leak, causing tension between husband and wife. Curtains can be used to cover one of the windows.
From the health point of view: ventilation at home can easily lead to diseases such as colds or strokes.
