Solution:
Method 1: Nail four advertisement nail on the four corners of the bedroom door. This is to use the stainless steel plane in the advertisement nail to reflect the so-called bad brake gas in the bathroom through the stainless steel mirror, so as to achieve the so-called evil effect.
Method 2: Hanging potted plants in the bathroom can purify the air and reduce the smell of the bathroom.
Method 3: Change the position of the door and the orientation of the bathroom door. This method is more difficult, usually before renovation, some buildings can't move at all, so it has great limitations. If you can, you'd better change it directly.
Method 4: Hang a bead curtain on the sleeping door. This is all reflection, strictly speaking, it should be diffuse reflection. You should try to shine a flashlight on the bead curtain. The reflected light is weak, and the bead curtain can not only solve the relative problem of doors and windows, but also be more beautiful.
Method 5: Plant tall plants on the vertical line between the bathroom door and the sleeping door. This is to avoid the hedge between the door and the door, so as to avoid the perceptual conflict between the two.
