okay, if you are going to china, like legit, then here's some tips as I've been there too.
-don't drink tap water, either boil it or drink water bottles. The water is not that clean, except for Hong Kong which isn't China.
-look both ways and cross the street carefully, don't get run over, I almost got ran over...
-food there is cheap, if your bringing money, bring a lot and buy stuff. electronics are a different thing. for food, it's really cheap, electronics in general are expensive, sometimes more expensive than here in North America.
-you won't get shot, no one has guns, only the military, either way to find a gun dealer on the streets is almost impossible (just sayin)
-when you take a taxi, they will floor it. Just pay what you need to pay, dont tip because they just scared the stuffing outa you when they swerved and passed 10 cars three times the speed of what everyone else is going.
