Here's the thing. I can't get a wife, so I have to drop in. But the woman said that the child should take his grandfather's surname. This makes me feel that the wind and water have turned around.

Don't care too much about the child's surname. It's not bad to come to the door. At least you can get rid of poverty, have a wife and a family, and be harmonious and beautiful. Children can take their father's surname or their mother's surname. If you answer the door, follow her and you'll be fine. You can also have two children, one with the mother's surname and the other with the father's surname. This is not the best of both worlds.

Fate is not to be missed. After this village, there is no such shop. Take care of yourself!
