Society is polarized, so there is a small society in the university. No matter in study, economic conditions, or interpersonal relationships. Take learning as an example. Some people attach great importance to learning. Even if there is no compulsory self-study every day, they still study consciously and get scholarships every year. However, some people don't go to class, stay in the dormitory all day, order takeout and play games, which ruined their four-year life. This is a very sharp contrast.
