College students are grown-up students, which have two meanings: first, they are students, so they should focus on learning. College students have a lot of time of their own, unlike high school which has classes every day. You can do what you like in your spare time. Of course, most of the time should be used to cultivate your own ability, and you can indulge yourself when appropriate, but you should indulge yourself within a certain range. Second, when you grow up, it means that you are already an adult. Adults should have their own judgment. You don't need to be reminded of what to do and what not to do. I think college life is synonymous with beauty, because your youth is there, no matter where your university is or what, you will dedicate your youth to her! Why not make her so beautiful!
