Which mean these guys don't have this. Something is missing within their personality, that is why they are coming to China. Chinese women beside being "quite beautiful with fantastic figures and lovely skin" as you said, are also smart and can smell a loser miles away. Guys realize you are not fooling nobody but yourself.
btw, by using a name like "Dimwit" you sound like someone with little self esteem.
