Those not speaking/reading Chinese fluently might be well advised not to plan on driving themselves around in a rental car. The traffic here moves very fast and those signs - well, I can't read them either. As an aside, all the photos in this series of housing, skyscrapers, etc. were taken through the window of a bus. Just a tip so you can think about taking your own photos right from the bus for you'll get good shots if you remember to shoot at a forward diagonal angle and not directly straight out from the window.
In China, Shanghai's architecture is certainly exciting visually during the day but just wait until night and it's even more so then. The lights on commercial skyscrapers throughout the central business area of downtown and the area of Pudong are incredible and a must-see for visitors.
