No idea what the narrator is saying at all but the visuals act as an excellent guide through the Walled City. A completely functioning and self governing city that now no longer exists, it used to be the most densely populated place on Earth. With 33,000 people living inside it's walls it was roughly 1 person to a sq. meter. Don't quote me on the math though.. I suck at it and this is what the internet said. Although these conditions would clearly qualify as "slum" conditions, aside from Triad gangs, prostitution rings, and opium networks, it seems most residents were not involved in criminal activities. I've been to a couple places in my life, but nothing compares to the tiny apartments in Hong Kong even today. The Walled City was just another example of what people can do with so little. A truly fascinating and complicated piece of Hong Kong history.
