My mother and father divorced. I want to change my surname in the new middle school and have a good outlook, but my father doesn't agree. Tell me, what should I do?

Are you afraid that because "his surname is Chen and my mother's surname is Zhang" is different from yours, your classmates will look at you differently? But you don't have to take it to heart, as long as your academic performance goes up, your classmates won't look down on you.

If you think this will really affect your study, find an opportunity to have a good talk with your biological parents and tell them that you want to change your mother's surname, so maybe they will understand what you promised. I wish you a new beginning, study hard and make progress every day!
