Nanjing is not one of the biggest cities in China. Despite a population of over 7 million, it has a modesty about it. The traffic though congested, flows along in a civilized way, a sort of ballet between cars, bikes, scooters and pedestrians. There are flashy shopping areas, but they aren’t enormous. Most everything is on a reasonable level, a human scale. Anything edgy or provocative is kept under wraps.
