This is interesting, there seems to be a growing industry in China in helping men pick up women. Its not really a mystery as to how this came about. China is a society who's generation-Y grew up in a much more liberal society than their parents. Marriage was often arranged and happened early. Dating was not a typical part of the process. Todays generation of Chinese men didn't learn how to socialize with women from their fathers or the media, and so were left sometimes clueless on how to meet women.
So to supplement for a lack of a role model, Chinese can now attend classes on how to socialize with the opposite sex for a nominal fee of a few hundred US dollars. Keep in mind there are more men than women in China, so pickings are limited.
