You’ll typically find two classes of city buses in China: The cheaper “ordinary” (普通 = “poo-tohng”) buses, and the express ( 快= “kwye”) buses, which are more expensive but make fewer stops. Since bus stops are only in Chinese, figuring out which bus to take can be a challenge to say the least.
Pick up a city map, which will at least show the bus route numbers. Or better yet, look for an English bookstore to find a map in English. At a minimum, have your destination written in Chinese so you can point it out to locals while you flash the big, goofy grin used by foreigners around the world. And watch out for pickpockets.
