City Of Darkness Life In Kowloon Walled City 1993pdfl New -

Kowloon Walled City had a strict social hierarchy, with different groups vying for power and influence. The Triads, organized crime syndicates, controlled much of the city's illicit activities, while the city's own "sang-chu" ( literally "grass head") – a mix of gangsters, thugs, and fixers – kept the peace and collected protection money.
