7. Get ready to get pushed around.

It's no secret that China has a lot of people. Whenever you're in a public place, especially if it's during a holiday (which, by the way, happens frequently. I swear we have a holiday here every other week), know that it will be crowded. You might get shoved around a little (or a lot). Oh, and even if you've gotten a spot in line, don't be surprised if people cut in front of you or completely ignore the idea of a line altogether.
