I've never been to Hong Kong. I have been to Shanghai, but not long enough (at least one month) to get much farther on foot than Old City recommended restaurants. At that time, planners were still working out how to promote colonial charms of the neighborhood. But if I had, I suppose I would have wandered into a "quarter" that looked a lot more like Kowloon -- The ruins of a slum within an "enclave."

Kowloon photos immediately reminded me of locations in the film Push. Yes, and there it is.
