The reason why Nanjing Library needs to make an appointment in advance is to control the number of people entering the library and ensure to provide quality services in a limited space. Making an appointment in advance can avoid crowded people, improve the efficiency of entering the library and better meet the reading needs of readers.

The library reservation method is to pay attention to the official account of Nantu WeChat (scan the QR code of the official account of Nantu WeChat below), click the "Service Center" menu at the lower left, and then select the first "Booking into the Library" function in the upper left corner. Fill in the reader information correctly as required and select the reservation date. After the reservation is successful, the "Booking QR code" can be generated. When entering the library for security check, open the official account of Nantu WeChat WeChat, the service center and "Book Entry", and you can jump out of the "Book QR Code" and scan the code to enter the library.
