Is there a law in China that children must be given a surname?

Children can take their father's surname or their mother's surname.

However, the law does not prohibit you from taking his surname, as long as it is not too unusual, hehe. Too uncommon words, sometimes the computer can't get them out, which has an impact on the establishment of personal files! In short, how to choose a name is a personal act, and the law does not interfere!
