She's not wrong. Due to communist China's one child policy for decades and the Chinese traditional preference for having sons (read: many, many aborted female babies), the number of men vastly outnumber the women in mainland China now.
Consequently, in the 'sexual marketplace' there, the women call the shots.
Compare this with eastern Europe, where there are many more women than men. The opposite happens.
It's nothing personal, it's all basic economics of demand and supply.
