There is a Feng Shui character "福" above the door on the west side of the corridor of the corporate office building (as shown in the picture). I want to design another character above the door on the opposite side. What character should correspond to it?

For reference:

You can design the word "linmen" corresponding to the word "福" above the door on the opposite side. Everyone knows the meaning, and you are the door maker.

People who see it for the first time will naturally pay attention to the word "Linmen" because it is rare. Then they will also naturally correspond to the word "福" and may even recite "Fu Linmen" once.
