Today's society is more tolerant. For many people, they have their own freedom to dress, but they are often provoked by some people with a heart and think that they should be conservative as girls. It was many years ago. In my opinion, I think we should do things according to our own preferences. No one can interfere with your wishes. What you like to wear is your freedom. So don't always refuse a girl's pursuit of beauty because she shouldn't do it, which is unfair to girls.
Moreover, as a teacher, you should set an example instead of attacking girls' behavior for no reason because of some traditional old ideas. Don't you know that the psychological damage caused by your behavior to girls is indelible?
So I still hope that girls can choose their favorite clothes at will in the future, and bloom freely like the most beautiful flowers, and don't affect their happy mood because of some practices of others.
