Matters needing attention in joining a student union or a club:
1. Choose your favorite student union or club according to your hobbies. For example, if you like basketball, you can join the sports department or a basketball club.
It is not advisable to join more than three societies and student unions. In my opinion, a person's energy is limited. Joining too much will make him very busy, but he doesn't do all the work well.
3. Consider an interview. For example, the League branch only recruits about 10 positions every year, but there are often forty or fifty people competing, and everyone wants to join a good department. Therefore, even if you want to join a department, you should combine your own situation and registration. Of course, there is no interview in general clubs.
