Zhengzhou is a hearty working class city I'd want to compare to what.. Philadelphia or how about Hamilton in Canada or Detroit or Liverpool in the UK by this I mean the people are rough and blatant and can easily be surly if they feel like it. I dont know why young foreigners insist on going to bars at night in Zhengzhou but that is absolutely asking for fights with locals yes. Zhengzhou really does have a reputation for scam artists, schemers, rip-off artists and by the way do NOT screw around with the local muslim people. I do believe it once held a record for the most noise pollution in decibels of any city on earth (seriously not joking) and yes they tend to have no respect for foreigners. Add to all this Zhengzhou people tend to be husky. Big old husky types. And thats just the women. but like some of those hearty working class former-steel towns its also true Zhengzhou has its own certain charm and people are, at least, real and more down to earth. but nobody should really want to go there. It really is full of rude, mean, dodgy and pushy people. also extreme particle pollution.
