Does the son live in the master's room?

"Master bedroom" and "second bedroom" have not been clearly explained. Is the "master bedroom" the bedroom of the "master"? Or the "master" bedroom? As you said, the real estate license is your name, and the "master bedroom" should be the "master's" bedroom. So which room does the "master" live in? This is the "master bedroom"! It is not the size of the room that distinguishes the master bedroom from the second bedroom. So no matter which room you live in and which room your son lives in, it is normal and will not affect Feng Shui.
