As we all know, the library is a public place to learn English. So we shouldn't break the rules. There are some rules. First of all, don't talk or laugh loudly. Because if you talk or laugh loudly, you will affect others. Then, don't run in the library. Finally, we should keep the library clean. So we will have a better learning environment. If we follow these rules, our library will be cleaner and more beautiful! Let's create a better learning environment!
