I was on a taxi journey in Shanghai with a very intelligent young Chinese student, who was helping me with interviews and interpreting. She was shortly to study for her doctorate at a top American university. She casually mentioned that some Chinese students who went to the US ended up marrying Americans.
I told her that I had recently seen such a mixed couple in Hong Kong, a Chinese woman with a black American. This was clearly not what she had in mind. Her reaction was a look of revulsion. I was shocked. Why did she react that way to someone black, but not someone white? This was over a decade ago, but I doubt much has changed. What does her response tell us – if anything – about Chinese attitudes towards ethnicity?
