When you borrow books from the library of Polytechnic University, just don't take your bag with you. Newspapers, magazines and documents in the library of Western College are not lent out, but can only be read in it. If you want to know what books to put on the floor, go to the stairs. There are signs on each floor. It is necessary to swipe your card, and photos will be displayed on the computer, but it doesn't matter if it's not you. Usually you don't ask. If you ask, just say it belongs to your classmate, no problem. The library of China Normal University is not very clear, and it has never been killed. . . . . .
