Oh, you can go to the secretariat of the Federation of College Students' Associations or the Association Center and ask which association you want to join. You can tell them that the office is in Block B, Wu Hui, and you should not have finished your membership card. You can go to the club center of the Federation of College Students' Associations and ask what clubs there are. You can meet the person in charge of the relevant club at 9: 00 pm, or you can ask the contact information of the person in charge of the club and contact them in the secretariat. This is not a big problem. It is neither troublesome nor strict for the club to recruit members.
