The library card of Shenzhen Library is common in the member libraries of Shenzhen "Library City". That is, member libraries that have participated in the "unified service", such as district libraries. If it is not a membership library, you should ask the service desk whether the library has opened the "borrow-and-return" service with Shenzhen Library.

Library:

A library is an institution that collects, sorts out and collects books and materials for people to read and refer to. As early as 3000 BC, libraries appeared. Library has the functions of preserving human cultural heritage, developing information resources and participating in social education. Library is the external storage and selective transmission mechanism of social memory (usually expressed in written records). In other words, the library is the memory device and diffusion device of social knowledge, information and culture.
