There are many clubs. I suggest you join the Youth League. Personally, I think this is more meaningful. There are often volunteer activities.

Anything else? . I won't think about it.

Don't join too many clubs. I suggest two. Two is enough. If you add more, you will be too busy. .

It seems that joining a club will not help much in the future, but there will be a comprehensive evaluation every semester, and club participation will account for one of them, with a full score of 1 plus a 0.5 point (so both can be done, that is why).

Go to the school post bar or official website to have a look. There is still a lot of useful information in it.
