Post 169656 by marycatherine deleted for the following reason: Hey, sorry, this personal "here's my take/experiences on the subject" framing isn't the Metafilter convention. Here, posts just present the links, and then personal takes go in the comments. (It's fine to just try this again tomorrow.) Also, probably better to separate the Kowloon Walled City stuff from the Shanghai stuff; they seem like separate enough subjects to warrant their own posts. -- LobsterMitten
