Does a door without a door frame count as a door? Is feng shui particular?

Well, a door without a doorframe is extremely bad in geomantic omen. If you buy a door without a door frame, or later install a door frame, it is an act of revealing evil in geomantic omen, so if you press the door, you must choose a door with a door frame, just like a man without clothes or an animal without fur. In this case, feng shui is not particularly good in the sense of survival, so when installing the door, you must press the door frame. This is the place where Feng Shui pays special attention, and it is also the place where Feng Shui pays special attention to its significance.
