Legal analysis: The application for joining the Youth League does not need to be stamped by any department. It only needs to be voluntary and express one's wishes in writing, and then submit it to the class teacher or the Youth League branch of the school, or to the unit or company where you work. Just go to the head of the department and wait for the inspection and approval of the group organization. After joining the Communist Party, league members still retain their membership. If they are over 28 years old and do not hold a position in the league, they should go through the procedures for leaving the league and no longer retain their membership. If a member of the group fails to pay the tour fee for six consecutive months, fails to participate in the group's organizational life, or does not do the work assigned by the group organization for six consecutive months without any reason, he will be considered to have left the group on his own initiative. If a member leaves the group on his own initiative, the branch meeting shall decide to remove him from the group and report it to the superior committee for approval.

Legal basis: "Regulations on the Political Review of Military Recruitment" Article 12 The determination of party membership and league membership of citizens applying for recruitment shall be based on the "Joining the Party" issued by the Central Organization Department of the Central Committee of the Communist Party of China and the Central Committee of the Youth League of the Communist Party of China. "Volunteer Letter", "Volunteer Letter for Joining the League" and the relationship between the Party and League organizations shall prevail.
