Even if this is true all over, how does this make Chinese men more palatable? It does not. But I know from experience across the US, and I have dated and had relationships with women across the color and ethnic spectrum,
given the option between a Chinese man and a white American, the Viet gal will take the white man over the Chinese man %99.999 of the time. Even in Viet Nam, the only Viet girls who will marry a Chinese man will be the poor and uneducated farm girls. Think you can score in downtown Sai Gon?
