Online renewal needs to be handled on the self-service computer on the first floor of the library lobby. The username is your library card number, and the password used to be four zeros. Those self-service computers often break down. If it is the first time to operate, you can ask the students around you there and ask others for help. If you have any questions, you can also consult the teacher in the central office, next to the elevator in the lobby on the first floor.

In addition, the renewal should be completed before the book expires. The fee cannot be renewed after the expiration. You can only return the book as soon as possible and pay the overdue fine. When you lend your library card to others or transfer the books you borrowed to others, you must remember clearly. Otherwise, if you lose it or forget to return it, you won't know if it's your own fault or someone else's fault. You want double indemnity. If you forget to return or lose books within the time limit, you must deal with them as soon as possible. If there is a record of breach of contract on the library card before graduation, it will affect the graduation certificate and be more troublesome.

I wonder if you are satisfied with this explanation?
