Can other people's used mirrors be bought back and put in the shop? Is there any feng shui stress?

First of all, I want to emphasize that no faith or superstition can bring any change to our wealth and family situation. We should treat everything scientifically and rationally.

Mirrors are used to reflect objects and increase light and vision. Feng shui, which has a bad influence on social atmosphere, refers to the situation of residential bases and cemeteries.

So it doesn't make any sense to buy someone else's used mirror and put it in the store.
