Generally, you can hang words and mirrors, hang something and stick something. There are requirements that are not terrible and complicated. This is what feng shui says. If you don't point at people, you won't scare them, and it's not easy to see them carelessly. Sometimes at night, there will be a terrible hint that the subconscious mind can't remember anything, which will make you have a heart attack. Secondly, words can reflect people's character and sentiment and should be placed in the living room. The bedroom is private, so it should be hung less and posted more in the cupboard. Be warm, there is a harbor when you are tired. To put it bluntly, I think all pornographic things are better than words. . .
