There is absolutely no need to hang calligraphy and painting. No matter how big your beauty salon is, you will eventually feel that there is not enough space. You should hang up the product information or materials of your beauty salon, and also make some friendly or popular projects you have here. It would be better if you hung up the rules and regulations of your store. In addition, you should leave a place to take a group photo and set up an honor wall (the honor wall shows the comparison of your customers before and after, so you must choose the best and most convincing one). Plan it yourself. Do you still have room to hang calligraphy and painting?
