What are the primary sources of income for the Triads?

The Triads, a well-known organized crime syndicate originating from China, primarily generate income through gambling and prostitution. This is especially true in regions where they maintain significant operations, such as Hong Kong and other parts of Asia. Gambling has a longstanding cultural significance, and the Triads often control illegal gambling operations, including underground casinos and betting rings, which can yield large profits.

Prostitution is another key income stream for the Triads, who may run or manage brothels and other sex work operations. They often exert control over these enterprises by using intimidation tactics and violence to manage competition and ensure their operations remain profitable.

While the other options do represent activities associated with various organized crime groups, gambling and prostitution distinctly outline the core economic activities historically linked to the Triads. Thus, the combination of these two activities forms a substantial foundation for their financial operations and influence.
