Better walk fast in Shanghai on a sunny day

This past weekend was almost pleasant, weather-wise. The temperature almost hit 50F so Shanghai residents were out on the street in lounge chairs, playing card games and airing out their blankets. In fact, one neighborhood I was in was almost covered in blankets - they were stretched across overpass stairways, bushes in the parks, even on the sidewalks. I decided I had better walk a bit faster than usual least someone drape an old blanket over me.
