I am a sophomore girl, and I want to mix well and be a big sister. What should I do?

Two ways. The first is to throw money. Invite friends and classmates to dinner if you have nothing to do, so that they will all think you are very good and listen to you. If you have more friends, you will naturally become a big sister. The second way is to fight, specifically hitting girls, which makes you feel uncomfortable. If you win, everyone knows that you are the eldest sister and dare not provoke you. There are only two ways. Either be a monitor in the class or a powerful member in the school, otherwise you really can't be a big sister. Hope to adopt
