Give the fact that, at least since the 1840s, Shanghai was the hub for Western businesses that had a branch in China, most of the city is cosmopolitan if not futuristic in appearance. The prime are is The Bund, which is the western shore of the Huangpu river, bordered mostly by 1930s art deco edifices. Across the river, ultra modern sky scrapers define the Pudong cityscape.
Very inconvenient to be in the Shanghai metro during the rush hour!
