Write down your experience, such as what position you have held and what activities you have participated in. If you just want to enter the discipline inspection department, then you should focus on your experience in this field. As long as you enter the student union, it doesn't matter how much you write. You can even ask the old members of the student union who want to join and leave a good impression on them. In fact, the resume is nothing, just write it carefully, and the places where students will eliminate people are mainly probation period and interview. You should be a freshman. Let me say a few words: professional knowledge is always more important than student union. You should know how to make better use of your time, because students will waste a lot of your time doing unnecessary things. Don't learn the wrong direction when you go in. The key is to learn a good habit and attitude, instead of imitating official flattery, pandering and drinking.
