Eat indiscriminately. The library is a place to study, but some people always bring some snacks or food to the library to eat, but you are convenient for your own time, but have you noticed the feelings of others? The sound of eating and the smell of food have a great influence on others' study, so you should pay attention to it in the future.
Noisy people. The first element of a library is to keep quiet and not disturb others' study. However, many students are accustomed to their own way of life and ignore the feelings of others. Often when they are in the library, they will unconsciously raise their volume and make a loud noise, which is easy to be thrown out by others.
Show love. A strange phenomenon in many libraries is that many couples choose to date in the library because they think the atmosphere in the library is much better than that in other places. But as a couple, it's no problem for two people to study together, but it's disgusting if you come to show your love instead of studying.
