Is it good to hide the feng shui of children in the door? How to deal with it

The "hiding" that the landlord said should be "the door stack". When opening a door hole in a thin wall, in order to facilitate the placement of the door frame and ensure the stability of the wall, the square stone that must be set at the corner of the door against the wall or at the side of the T-joint wall is the door crib. Like the beam, it is a protruding beam, generally parallel to the door. If it's vertical, it's a beam, just like a sword stabbing into the door. Of course it's good.
