People will feel happy, the environment can affect people's mood, and a good environment can naturally bring happy mood. A happy mood can also improve your study efficiency and make you feel that you are in good order. During my college years, the sanitary problems in the dormitory were never too bad. Everyone is responsible for his own hygiene. They buy trash cans and garbage bags. There is no rubbish on the floor, and they can even take off their shoes. They can walk around the dormitory barefoot without feeling dirty. I clean the dormitory every week. When I say cleaning here, I mean cleaning the whole dormitory, that is, dust and the like. Of course, sometimes when I am busy, I will clean it once every two weeks. I can't be picky about the dormitory environment, and I can sleep, study and live in a comfortable environment every day. In the latest popular online language, it means "Hey, I feel my life has reached its peak". Yes, that's the feeling. That's great.
