I am a junior high school student, but I think my hairstyle is ugly. What if my new classmates laugh at me?

It doesn't matter. What's wrong with your hairstyle? It's called character, and others haven't. Laughing at you? Is he qualified to laugh at you? He's not even your friend. What do you care about him? I'm afraid locusts will fly to your house, so I won't farm.

I'll give you two ways to handle it. The first way is to ignore them completely, because they are just boring, so you have fun.

Second, warn them of this behavior, but you must have the capital to suppress them.
