The reason why you put the book back after reading it.

The ancient cloud book has its own golden house, and the book has its own Yan Ruyu. Now, everyone can enjoy the sea of books, find the true meaning of life in books, and explore the future road in books. At the same time, for the sustainable development of the library and for everyone to study hard all the time, we should strictly abide by the rules of borrowing books and make corresponding penalties for unfriendly behavior. I hope everyone will supervise and encourage each other and jointly safeguard the library that belongs to each of us. The books in the library room should be read open-shelf. When reading, everyone should go into battle lightly and put them back after reading.
