Can you put a stone behind the sofa as a backer?

Hello, landlord. Excuse me, is your living room big? If there is a place to put the sofa, I suggest you make a small rockery. Keep some goldfish in it according to Feng Shui. Your arrangement is very good. There is water behind the sofa, which is called Feng Shui. The host seat at home is healthy and worry-free.
