Dai Huen Jai
The Chinese Triads are remarkable for their ability to thrive even under a Communist regime, hiding in plain sight in normal society while pulling all kinds of illegal acts. One of the most notorious of the triads is the Dai Huen Jai, also known as the “Big Circle Gang.” Like many of the gangs on this list, the group got its start in the military. After Mao died, many members of his “Red Guards” were sent to re-education camps. Naturally, after being betrayed by the same government they served, these guys were pretty pissed off, and they escaped to Hong Kong to lay the groundwork for a global criminal organization. Because the Dai Huen Jai operates in small, loosely-connected cells, it’s difficult to get an accurate picture of their size. We do know that they have extensive drug smuggling and human trafficking operations all over the world.
