In college, why do some dormitory people like to buy wallpaper? Although I don't know what wallpaper is, I don't think it is necessary to buy it.
Wallpaper, this is love. Well, some people just like to decorate their rooms. For example, if you buy a house, you have to decorate it, right? The reason is the same. Even if you decorate, you will be in a good mood when you like to live. Wallpaper is not very expensive, there are various prices.
