In principle, we can't, because after all, the library is a place where our own school provides books and learning for teachers and students. Therefore, the school library implements the credit card mode, and it is generally impossible to get in without a library card. But if you really want to study in the library without a card, you can try to apply for a temporary library card in the lobby on the first floor. It seems to be green, but I'm not sure exactly. Good luck. . .
