Triads currently engage in a variety of crimes from extortion and money laundering to trafficking and prostitution. They also are involved in smuggling and counterfeiting goods such as music, video, and software as well as more tangible goods such as clothes, watches, and money. Counterfeiting Triads have been engaging in counterfeiting since the 1880s. Between the 1960s and 1970s, triads were involved in counterfeiting Chinese currency, often of the Hong Kong 50-cent piece. In the same decade, the gangs were also involved in copying books, usually expensive ones, and selling them in the black market.
