Shanghai Etiquette 4

At times Shanghai sounds a bit like entertainment from the late 70s early 80s, in particular Bob Carolgees and Spit the Dog.

There is a good reason for this… Internal moisture harbours all sorts of germs. So in China feel free to spit out any moisture phlegm and anything else you can to keep your insides clear and the germs in the outside world where they can run free.
