The males rarely, if ever, marry outside their nationality. It’s one thing for the sister to have ‘funny looking’ kids, those kids don’t have the family name.
I’ve known and worked with dozens of Chinese descent men and women. This was THEIR explanation, btw.
I’ve known exactly one male who married outside his nationality. He softened up his parents by telling them he was gay. And about 6m later introducing his white girlfriend and stating she’d cured him. His brother was doubly pressured to marry Chinese at that point.
My experience is different.
I believe the Japanese are very nationalist but not the Chinese. I work for a Chinese company and all the Chinese guys here tell me to come back to China with them and they will hook me up because all the girls there want a western boyfriend. In fact, one guy at work recently introduced me to his sister in law and we have just started dating and previously another Chinese Girl I worked with set me up with her friend (It didn’t work out).
Asian guys generally have a had time dating outside their race because they are generally short and/or thin and aren’t good looking (Not to mention the stereotype of them being very small you know where).
But yes it is true when it comes to other races, Asians are very racist against Blacks, Hispanics and Indians and such.
