That's incredible.
China was, strangely, quite aggressive in the two big cities. They didn't accept tips because it loses them face but they didn't mind arguing in the street and violence seemed ready to explode at any given moment. First night I was in Shanghai, there was an incident involving some triads at a club which I have yet to figure out. Basically, every foreigner in there (which was pretty much myself, two mates and a couple of girls) was escorted through the kitchens, out the back door and into taxis because it was about to go off massively.
Saw a bloke take a nunchuk to the head in thailand because he didn't have the right bus ticket as well. 😆
