It's easy to do. Librarians need to sort out and code more books and put them on the shelves for readers' convenience. At ordinary times, we should also do a good job in library borrowing, book maintenance and book registration. Although the work is trivial, librarians can read more books more conveniently than other occupations. You can also further improve your knowledge and ability and enrich your life experience. It is a good job without too much pressure.
