Do librarians in Shenzhen need to be certified?

No need. Librarians need to organize, code, and put books on the shelves to facilitate readers' access. There are no hard technical requirements and no verification is required. Librarians can be promoted to heads of their departments, or transferred to departments such as the librarian's office or business committee. Through extensive knowledge acquisition in the library, you can move to secretarial, book publishing, book editing and other related industries.
