Spit

If you walk around long enough here in China, you happen have to notice the spitting. Chinese people spit much more than people in Europe or America. I am not casting judgement, I am simply making an observation. Someone once explained to me that it is because Chinese people, like people in Europe or America, suffer from respiratory congestion at times. When there is a clog in the chest or throat, a Chinese person does not swallow it down to try to create room in the passages. Instead, they spit it out onto the pavement.

When you consider it from a health perspective, it makes a good deal of sense. Aestetically, however, its pretty gross.
