It's maybe true.
My co-workers (洋人) and I went to Foxconn in China many times. They couldn't remember the Chinese girl faces there at all. More than ten times, my co-workers said to me, "these girls must be from one family. they all look same". I just smiled at my co-workers because I know my co-workers got confused again.
Feelings are strongly-related with cultures, which are strongly-related with history.
hence i feel hard to agree any 中外 marriage. No background even both educated..
I had a teacher who is a Chinese American, who is short, not rich, nobody in China would think he is a handsome man, married a Tall beautiful white woman, they have 3 children, they have a very happy family for sure.
