If your daughter is dating a Chinese man, it’s probably because he’s a good, kind and smart person. If this man makes your daughter happy, isn’t that the most important thing? As for mixed-race grandchildren, no matter what their ethnic makeup, they’ll still be your grandchildren, still your blood. They will deserve and need your love. You shouldn’t love them less because they’ll be half-Chinese. I hope you will support your daughter in whatever descision she makes, and encourage her to seek her own happiness.
