To the Han Chinese even a half Han Chinese kid is lesser. And I am not talking about a half Han Chinese and half some flavor of European or some flavor of African. I mean half Han Chinese and half Tibetan or Korean or, especially, Japanese.
I have a Chinese friend, a medical professional, whose last name is also a common Korean last name. His office is near Koreatown, but he has no Korean patients. He has no animosity toward Koreans but says that when Koreans call him to inquire about his services, they hang up when they find out that he’s Chinese.
