First: Feng Shui theory really pays attention to the "door", "master bedroom" and "hall" of our room. It is considered that the door of "master bedroom" cannot face the door of auxiliary rooms such as "kitchen" or "bathroom". This is because, in our home, the door of the master bedroom is facing the door of the "kitchen" and "bathroom", which is easily affected by some suffocation in the auxiliary room. Not good! But here is mainly about the relationship between our master bedroom and the auxiliary room door. Of course, between the master bedroom and the master bedroom, the door is not suitable. But what you said is that your master bedroom is facing the door of the study, which is not important. So the two rooms don't conflict too much! Please don't have too many psychological bad feelings!
The best and simplest way to solve this problem is not to always open two opposite doors. If the library door is open, close the bedroom door. Because, when people study in the study, they should concentrate. If we see the bed, it is easy to feel sleepy.
Secondly, if you are not at ease, you can also put a pot of green plants (not Guanyin) with big green leaves between the two doors. This can not only ward off evil spirits, but also make money, and also play a role in greening your home. Only in this way can I wish you and your family peace and happiness!
