Maybe every man has a different answer to this question. In other words, this is a controversial topic.
Mainly depends on the man's personality, his family background and personal ability.
I think of a novel by Yu Hua, Alive.
Friends who have read this novel should know that Xu Fugui, the man in the movie, was originally a landlord family, but later he was frustrated in the casino and gambled away all his possessions. At the beginning, Fu Gui and his father-in-law were a match made in heaven. Later, Fu Gui's family was ruined and his wife was taken away by his father-in-law. His wife was pregnant with a second child. After birth, the Fu Gui family paid more attention to their son's surname. Is the child still a surname? Xu? After hearing the news, Fu Gui and his old mother laughed for a long time. Visible, since ancient times? Children take their father's surname? This is the traditional concept of China people.
If it were me, I would have a hard time accepting it. Personally, I am more traditional. Even if the woman doesn't want a bride price, I can't stand it if she makes me take my mother's surname. That's because I have enough independent financial conditions to afford the bride price, and I am an only child, so it is difficult for me to adopt, let alone let the child take the mother's surname. So, on the whole, I don't think I need to find such a wife at all.
Of course, not all men are like me. There are many men who can't help themselves. Some men come from special families, either their parents divorced or their biological mothers died young. The broken family originally made his dream of starting a family very extravagant. At this time, let alone let him buy a house and a car, even if it is a basic bride price, it is estimated that he can't bear it. If such a man, in order to give in to life and give himself a home, even if he is adopted by his wife or his child takes his mother's surname, I think it is acceptable and understandable. So-called? People have to bow their heads under the eaves? That's the truth. Since it was adopted by her mother-in-law, it is up to her parents-in-law to change her surname in the future. Why not?
There are many examples of letting children take their mother's surname. Even if there is no adoption, the man has financial conditions. For example, I have a friend who gave her child a surname after she got married, because her husband loves her so much that he doesn't care who the child's surname is. Why can't a son-in-law who wants to be loved by her parents-in-law make sacrifices?
Since the country implemented the second child, the number of families with second children has increased. At this point, one of the two children can take the mother's surname. Especially now, many treasure moms and dads are only-child families. For the sake of the woman, it is understandable to let one of them take his mother's surname.
In fact, if the man doesn't care, the child has the same surname as anyone else. As long as the husband and wife live a happy life and the children grow up healthily, what is the name of the children? What is there to argue about?
