Do people who know Feng Shui have a mirror facing the stairs at home?

The mirror faces the stairs. When you go up and down the stairs, you are usually looking at the stairs. When you walk up the stairs, you look up and see a man appear in front of you. Do you feel horrible? It's not good to put a mirror. The mirror in the bedroom can't face the bedside. In the same way, it is still terrible to get up at night and go to the toilet and turn around to see a person in a daze! ! ! So it's not good to put a mirror!
