Too many people ?
One thing I will absolutely never will understand about China is their utter disregard for the man-on-the-street !! Despite being exposed to extreme traffic conditions in India – I am surprised. While crossing the road on a zebra crossing with a green light on for pedestrian crossing, I have got into habit of looking at "ALL" directions for an approaching vehicle. There is a right of way for vehicles turning from right even in the conditions stated above. Then there are cycles. Cycle traffic seems to be governed by a very thin rule book – probably written in English (that means a typical local cannot fathom a bit of it) - essentially they come onto you from anywhere, anytime. I have narrowly missed getting hurt / collided couple of times.
