Will the mirror be placed by the stairs for feng shui?

Is the staircase facing the gate? Stairs are divided into internal air stairs and external air stairs. It is lucky to unload the stairs inside, but it is unlucky to open the door and see the mirror outside. Mirrors reflect wealth. If the door is not facing something dirty, it should not be facing the door. Mirrors generally have the function of blocking evil spirits, but they should not be facing the bed.
