I came across a video on Youtube discussing it (there are several), and Kowloon Walled City is just endlessly fascinating. A few notable videos I found on the subject were:
Kowloon Walled City: Hong Kong’s City of Darkness
Inside Hong Kong’s Kowloon Walled City
There is also a book on the city called City Of Darkness Life In Kowloon Walled City, which I found on archive.org in high resolution. It is full of photographs and detailed accounts of the comings and goings within the enclave.
Can you walk me through how you arrived at the idea that Kowloon was a product of communism, and explain when and why the Chinese decided to insert it into Hong Kong? Sorry if I’m a bit slow, but what you wrote runs counter to everything I thought I knew about the topic.
