One form of urban transport common in Chinese cities when I was working there were the little private buses-unmarked-that ran either obscure routes or picked up the extras from the municipal buses.
A good way of exploring a city is to stand at a bus stop and jump on the first bus to come along. With a standard RMB1 or RMB2 charge not a lot of mental effort is required.
I was standing at a bus stop in Zhanjiang when the first bus along turned out to be one of those small and unmarked local buses. I jumped on and away we went. The 'conductress' came up to me and it went something like:
C: Money, please.
Me: (with panic starting to set in at this unexpected development) How much?
C: Where are you going?
Me: (after a lengthy consideration of possible answers and then racking my brain for some Chinese words) I don't know.
C: (rolling her eyes as she communicated to the other passengers that she was dealing with a retarded foreigner) You don't know?
OP: (Other Passengers roar with laughter)
OP: (Other Passengers scream with laughter)
(I stand lost in thought for a moment ... a very long moment)
Me: Where are you going?
Me: Very good, Then I want to go to Chikan
OP (Other Passengers applaud)
