First of all, the dormitory is the place where you spent the longest time in four years in college, which is equivalent to your small home, so the sanitary condition of the dormitory is actually very important. Even if you don't want to decorate like me, I suggest that the dormitory be clean and tidy and comfortable to live in. Get on well with your roommates and clean and maintain public areas together, so you won't be so tired. Of course, if my roommate doesn't cooperate like me, then I have to consider whether I can accept an unclean environment. If I could, I wouldn't have to worry about such things. If not, hold a kind of "I clean for my own happiness" mentality. In short, it is good to run the dormitory as a master, as long as it doesn't affect others, anything will do.
