The term "Hong Kong Mafia" refers to various organized crime groups operating in Hong Kong. These groups are involved in a range of illegal activities, including drug trafficking, extortion, and illegal gambling. The most prominent among them is the Sun Yee On, which has a significant influence in both Hong Kong and mainland China. Historically, the Hong Kong Mafia has roots dating back to the early 20th century, with connections to the Triads, a broader network of Chinese criminal organizations. Over the years, these groups have adapted to changing political and economic landscapes, maintaining their power through corruption and violence while also engaging in legitimate businesses to launder money.
