Yes Damo, this thread is a real worry. This is the problem with China, one successful trip across it can make someone believe that there are is some kind of predictable outcome for every trip. China is an odd place, you can be beaten or even killed for being a foreigner or other times loved and treated incredibly well. The things you did had zero to do with the way you were treated, those attitudes all reside within the heads of the locals you meet, their potential behavior is unfathomable to everyone including them.

There is no logic to travelling in China, it's hard to understand from a logical western point of view. For example, if I drop sodium into water it will explode, if you do it it will explode too, if anyone else does it, the same result will occur. Travelling across China absolutely does not work like that, each trip could have a wildly outcome, like a different experiment each time.
