Here's a tsunami of bicycles in Chengdu.
And here's some of the night sky in Chongqing. CQ is at least as hilly as San Fran., so there are no bicycles there. I saw a total of four bicycles in three days there. I also took a motorcycle taxi one night - no helmet of course. I'd be happy if they even bothered to use headlights at night there. That was a pure adrenaline ride.
