Classmate, if the book you borrowed has expired before the holiday, you will have to pay a fine after the holiday. If the book should be returned during the holiday, you should return it within two weeks of the start of school without paying a fine. In fact, the fine is nothing, and 50 cents a day is just a form, urging everyone to return it quickly after reading it. If you need to continue using it, you can renew it online for one month on the library homepage.
