You don't have to make it complicated. I once knew a guy who invited a girl to watch t.v.- and after that they were a couple. He was not looking for a relationship. You just need to be exotic or have money, those are my observations.
The one about don't talk about politics or religion really took the cake. I don't know too many Chinese who know much about this stuff or care enough to talk about it. The only thing remotely political I ever heard here was about the Pescadores Islands.
It seems this stuff works more on western girls than Chinese ones.
