The reason why the bedside is not suitable for facing the door is because it is unlucky to face the door, because it will lead to a decline in one's health and career; So it should be avoided as much as possible. There are two ways to avoid it: 1. First, move the bed away to avoid the head being in line with the door, so as to avoid the head being washed straight by the outside air. 2. If the bed can't move, you can sleep at the other end, which is also a flexible and feasible method. This way, the bedside can avoid being washed away by the air outside the door.
