"The reason why the Walled City of Kowloon gets so frequently mentioned as a ruin is, while it was there, it was as if the people who lived in it were living their lives in the guts of some great, monstrous, maze.
"The city was a curiosity for a very long time – a strange bit of legal knotting making it Chinese and not British -- but the labyrinth didn't start to grow appreciably until after the second world war when it became a haven for... well, people without a state: refugees, squatters, thieves, drug-dealers, and much more (and much worse). Neither Great Britain nor China refused to have anything to do with the immense warren of walkways, apartments, workshops, factories, brothels, gambling dens, and opium dens.
Looking at pictures of the city today, it looks like some kind of ramshackle prison, a cyberpunk nightmare of florescent lights, spectrally flickering televisions, and mazes of perpetually damp hallways and trash-strewn alleyways. Yet, for many people living there, it was simply home."
