University is a place that gives you unlimited freedom and unlimited cruelty. There are too many depravities and too many temptations. In high school, even if my eyelids were fighting, I would look at the classmates next to me who were still working hard, and no matter how tired I was, I would still have to do a few sets of questions. Because others were working so hard, you would be embarrassed not to study. But now, when I feel that I am not working hard, I will look around and see that I am not working hard, and I am even more degenerate. Then I feel that I am embarrassed because I have worked too hard. So many people are eroded in this way, slowly transforming, unknowingly.
