Knock on a door between the two bedrooms in the east-west direction and seal the door of the master bedroom, will you?

No, sealing the bedroom door is very unlucky for feng shui of the bedroom door. The entrance of the door and the bedroom door are the energy switches for the bedroom owner to hide wind and gather gas. They are most afraid of mouth-to-mouth opposition. Feng shui believes that mouth-to-mouth is easy to offend, so it can be seen that the bedroom door is not good for feng shui. This situation is called "mutual scolding" in Feng Shui. In a house, if the door of one bedroom is opposite to the door of another bedroom, it is easy to quarrel at home, which will lead to emotional disharmony among family members. You scold me, I will scold you. It's difficult to get along with. The simplest solution is to change the door of a bedroom to the opposite position. I hope I can help you.
