The entrance door is the air outlet of the Feng Shui aura of the house. If it is facing the bathroom, it will receive the aura of the bathroom. The bathroom is a place with only yin and turbid water. It is unlucky to hit the door. You can ask the Five Elements and Bagua blessings to be pasted on the back of the door or the bathroom door to decrypt it.
