How to deal with the accent being laughed at at at school?

We should correct our mentality, respect our hometown, be proud of our hometown, and not feel inferior because of our accent. This is from our hometown mother. We should cherish it, and at the same time, we should practice our Mandarin. After all, I still have to work in the future. Many places need standard Mandarin. People who laugh at you will admire you as soon as they speak Mandarin.
