One of the benefits of riding in China or anywhere else, is that you participate in an activity with others there and begin to get an idea how the society operates. Of course there are rules that everybody follows, just when they are different than at home it seems confusing, but you learn them and this is the fun. Basically it is a point system and who has more points has the right of the way. You get points for having green light in your direction, but these expire when there is little duration left for the green. You get negative points for red, but they gradually expire as well. The greater the number of you, the more points you get. The bigger vehicle you are, the more points you get. The longer you wait, the more points you get. The more pissed you are and the more in a hurry, the more points you get - yes, people recognize that. There are some regional variations across the country concerning details, like rank of the pedestrian or bike rider, and you get these by the ear.
