I live in southern california and in my dating life met a lot of mainland chinese immigrant women.

They were some of the most difficult women I've ever met. Even when they were trying to be nice, I could see how pushy and domineering they were. Chinese society trains them to be cutthroat and overly assertive like that, because everyone else in China is so pushy that if you're not pushy yourself, you'll get nothing. Some of these women were hot, but they'd nag any man to death if he showed the slightest sign of weakness.

No other asian women are like this. Japanese women are the most chill, koreans can be high strung and competitive but they're not "alpha", viet women range from nice to hot/materialistic, etc.
