When in China, please play it smart, and dun act like you have a lot of money. The gals won't be impressed, they'll just think, ho sey leow, another Robert.
And please don't listen to that kuku who tell people to act garang, you are a foreigner, they take one look at you, straight away they can tell, act garang and you may end up on the wrong side of a parang.
Sure, unless you have 关系 with the 公安 or some 干部，and you have some guys in your room packing heat, sure go ahead and be garang...
