First of all, the library is a place to study. When you enter, you will be prompted: Please mute your phone. Remember, don't talk loudly, don't answer the phone in the library, it will not only affect yourself, but also others.
Secondly, we should cherish public property, no matter how small it is, because it is not only for our own service.
Get along well with friends in the library, don't argue over a little dispute, take a step back.
Borrowed books should be returned regularly, especially the borrowed books should be kept well and not scribbled.
If there is a manager to manage it, whether it is right or wrong, it should not be solved by violence, but should be handled as peacefully as possible.
