Whether it is useful or not is a matter of opinion. If you think it's useful, join the party. If it's useless, don't join the party. This is a question of motivation and belief. You have your freedom! That depends. If you are at school, you should pay attention to your behavior, because at school, party member's every move will have an impact on other students! Of course, you should pay attention to your image even if you don't join the party, shouldn't you?

If you want to take the civil service exam in the future and join the grass-roots work of village officials, joining the party has many advantages, so I won't say much!

In short, everything has advantages and disadvantages, it depends on how you weigh it!
