Hello. After graduating from high school, the league members' files are lost, so they can go to college or reissue them. There are two ways to solve the problem: 1. Fill in the file of the old high school. 2. The files of re-joining the League members include the application form, the volunteer letter, the League member card and the League member registration form (this transfer relationship need not be taken away, as long as the information compiled by the League branch secretary is enough). It is the basis for becoming a league member and the basic information for promotion to party member in the future. Be sure to keep it safe.
