Excuse me, how to solve the feng shui problem from the office door to the bathroom door?

Toilets have been filthy since ancient times, and it is not good for the office door to face the toilet door in the sense of geomantic omen. However, if it is facing the toilet door, don't worry. We can solve it in some ways. We can put a barrier between the office and the toilet to resist some dirty air, or put some feng shui potted plants at the door of the toilet to absorb some dirty air and purify it.
