I shudder to think of it but when a power outtage occurs, I suppose there's no other way to get to your apartment but to walk up the steps no matter what floor you live on. Oh, my!
The best views of the seemingly unending supply of highrise housing in Shanghai, China are from the elevated highways running through the city. You certainly won't lack for photo ops from them.
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.
The 27,000,000 population figure given by city tour guides does include the expats living in Shanghai. Expats, for those not familiar with the word, are people from any other country who are living there because their job is there, they are students, they have retired there from elsewhere, etc.
