A bit unrelated, but since people with Hong Kong knowledge may be reading: How are the Chungking Mansions doing? The atmosphere there was sometimes compared to Kowloon Walled City, and I remember when my roommate stayed there in the 90s he reported that from his window that faced the inner courtyard he could not see the ground, just darkness. Also, it was reported to have rats as big as cats and cockroaches as big as rats (I hope jokingly).
How is it doing now? Still as dystopian?
