It's no big deal to join an alliance. Join the league as long as you go to school, no matter how you write the application for joining the party. If you can't get into junior high school, you can get into senior high school, senior high school and college. Anyway, the school won't let every student go. You can even go in if you don't want to. If you lose your League membership card, someone will reissue it for you. Unlike joining the party, it takes a lot of effort. China has basically popularized league members, and the penetration rate is higher than that of nine-year compulsory education. You will understand later.
