First, after getting acquainted with classmates, communicate with others more. Don't talk when you first enter the university and find that your classmates are of low quality, otherwise others will not have a good impression on you. When I get along with my classmates, I will communicate with them and give them some advice. If they care about other people's feelings, they may gradually change their behavior, but if these students are too arrogant and unreasonable, it is easy to break up with you, and it is even possible for everyone to isolate you together. This is also a relatively normal phenomenon. If this is the case, don't worry too much. There are so many classmates that they can't play with other classmates. Instead of making friends with these people, it is better to stay away from them so as not to be influenced by them.
Second, stay away from the mud and don't get dirty. If your classmates are of low quality, but don't pick up after suggestions, then you stay away from people like them and are not worth making friends with. If people around you keep pushing themselves out, you can stay out of it and don't care what they think. It's good to learn to eat alone. In such an environment, everyone can concentrate on their studies without considering some interpersonal relationships. They can also go to other departments, find some like-minded friends, do sports on the playground, and maybe meet friends with the same hobbies. In a word, we should not make ourselves uncomfortable because of environmental problems.
