Chestnut, there is no Chinese ethnicity. Some of the hundreds of ethnicities that exist in China are Han, Manchu, Zhuang, Yao, Bai.
You are just trying to wriggle out of the question. Whichever one they were, they grew up with two different nationalities (USA and Norway). So if 'ethnicity is an unscientific concept' are you denying their ethnicity? They were twins, they both had the same ethnicity, even though one was American and the other Norwegian in nationality.
Well, that was a farce.........
