When entering the library, the security guard needs to see the campus card. You can't get in without it. Even if you pass the security guard at the gate and go into the library and want to lend it out, you must swipe your campus card, and it must be your own campus card. Therefore, it is impossible for people outside Henan Normal University, who are not students, to borrow books from the school library. But teachers of Henan Normal University can certainly borrow books.
