China's existing "League Constitution" clearly stipulates that China youth can join the League only when they reach the age of 14. If 12 years old joins the league, it is against the provisions of the articles of association and should be corrected, and the handling personnel should bear the responsibility for violation of discipline. The young man's membership should be revoked.

So 12 years old, you can't open a certificate, and you can't join the league if you have a certificate. If you issue false certificates, you will be punished.

According to the time of joining the membership card, it is estimated that you are 14 years old or older. If you are not satisfied, write a certificate to the original school.

There are several ways to check the exact time of joining the League:

1, check the membership card. The membership card clearly States the time of joining the league. As long as you find your membership card, you can check your membership time immediately.

2. Ask about the membership application. When you join the league, you will fill out an application form for joining the league, and you can find out your time of joining the league on this application form.

3. Check the documents. Fill in the application form for joining the League and formally become a League member, which will be recorded in the Youth League file. Find those files and check them out.
