Oh, now you're asking a tough question! Have you spent long in Asia? I'm afraid that this is just the way it is there. Boys and girls don't usually hang out together unless there is a romantic force underpinning their friendship. I learnt this the hard way. In any case, as a visitor to Asia it's your responsibility to adapt your way of thinking to the Chinese way, and that probably means it's best not to spend too much time with girls who you have no romantic interest in, because if you do they will undoubtedly misread the situation.

because the culture is different,we cant talk fluently,it just like a wall.u in guangzhou now ?haha ,me too.

As James said, this sort of platonic friendship is not yet culturally acceptable

It depends on how you act when you are hanging out with them.Yeah.. but true it's easy for Asian girls to be confused. The best way, I suggest, is to state clearly at the first place that you are just looking for a friendship not something romantic. Maybe they tend to believe it is leading to something romantic only coz u r too attractive.;)

Maybe the main reason is that we have diffreent cultures. After you know our culture better, you will understand it.
