Describe that the toilet door in the room is perforated (the toilet also faces the bed).
Good or bad luck leads to inexplicable diseases.
The solution can be solved by setting an opaque screen. Or hang a long opaque curtain on the door and place a group of white jade gourds and five emperors' ancient money at the threshold. The size of the door curtain is 30 cm from the ground, covering the toilet seat, while keeping the toilet clean and closing the toilet door frequently.
