Big cities have this way of resembling beehives, busy, constantly moving. Most of these urban centers are jarring, fast, harsh, noisy, and unforgiving to all that is slow. Not Shanghai. Shanghai has a gentle flow about it, where people just glide by on their bicycles, slow enough to examine life around them and nod with recognition at friends in their neighborhood. A bicycle and tricycle culture, so much is moved around on wheels. As long as tradition lasts, this will be (at least to me) the greatest charm of Shanghai.
