I don't think I've ever been in a lift that's actually been filled to the stated 'maximum capacity' before - I'd always thought it impossible. Not in Shanghai. In fact, they appear to have misread it as 'required capacity'. They've not yet exceeded it though, so I'm sure I'm quite safe. It's quite difficult counting 27 heads in a lift; it would've been impossible if I hadn't been the tallest.
Casually wandering the streets of Shanghai is a bit like casually wandering the department stores at home...at 9am the day the end of year sales start...but with the sales staff shouting at you "t-shirts, watches, dvds" and everyone else shouting at each other. I was being accosted so much on the street I pretended I didn't speak English, but they then adopted that tried & true solution when speaking to anyone who doesn't speak English. Just speak louder. I have entered "shouty world".
