In the school stage, life mainly comes from the family, and the parents in the family are older. The library is the document information center of the school and an academic institution serving the teaching and scientific research of the school. The reason for applying for the work-study program in the library is that it is in the learning stage, and life mainly comes from the family, where parents are older and family sources are relatively single. Considering parents' life and family expenses, they can bear more family economic responsibilities on the premise of ensuring their studies.
