I had the chance to go to Shanghai when I lived in Beijing, never did, kick myself in the butt for not going! Theres a fair amount of the old city left right? I think they preserved them with city ordinances, at least thats what I remember reading like 1o years ago. Beijing was destroying a lot of their ancient city, really a shame, although historic preservation is starting to catch on there as well, but a little too late for a lot of the city.
“A photographer went to a socialite party in New York. As he entered the front door, the host said ‘I love your pictures – they’re wonderful; you must have a fantastic camera.’ He said nothing until dinner was finished, then: ‘That was a wonderful dinner; you must have a terrific stove.” -Sam Haskins
