Building a house in the past will avoid this phenomenon, and the door of the house will be affected relatively, but it is really unnecessary. Especially now, sometimes we don't even see each other across the hall, so there is an intersection.

One of the reasons why feng shui is not good at home is that people have good feng shui. Since people have good feng shui and open the door to recruit boatmen, those who have bad feng shui have not entered their own homes.
This is just a matter of course, it is really unnecessary.
