On the issue of children taking their surnames.

should it be all right? How many generations have my father's grandfather been? Who will pursue so much? What's more, if the child has done nothing wrong at all, what's wrong with taking his father's surname aboveboard? I think you should not only think about how to convince the father of the child, but try to convince yourself. Just taking someone else's last name instead of your father's will attract more weird eyes, right?
