In China, it is a custom for people to take their father's surname, just like a product is branded in a factory. I don't know whose son you are.

But the name should be changed to household registration book, ID card and so on.

Moreover, if you have some legal documents, certificates, bank cards, household registration cards and other things that need to be modified and used, I suggest you change your name carefully, otherwise it will be very troublesome in the future. For example, if you lose your bank card, you have to go to the police station to reissue it. Now "you" is the former "you". . .

A name is just a title. If it is not ugly, I don't think it is necessary to change it. . You haven't read too many martial arts novels, have you?
