The books you borrowed (except those borrowed from the source of new books) are not finished by the latest return date, so you can renew them once (for 30 days) within one week before the latest return date.

Method 1:

It is to renew the book at the original lending office.

Method 2:

1. Do it yourself online. You don't need to make an appointment. You can renew it yourself online. The renewal method is as follows: log on to the library homepage and log on to "My Library".

2. Enter relevant information and select "Borrow and Return Books" for reader service.

3. Find a personal borrowing record, focusing on the time of borrowing and returning books.

4. Click to enter the "book renewal" option.

5. Select the books that need to be renewed, tick in the small box in front, and then "renew".

6. After the renewal is successful, the return time of the new book will be postponed, and you can continue reading during the borrowing period.

Note: Be sure to pay attention to the time of returning the book. You can't wait until the loan expires, otherwise the renewal function will not be supported.
