Jimmy Tsui is a former member of Tung On in New York City's Chinatown and of the Sun Yee On triad in Hong Kong. In 1985 in New York, he was arrested and charged with robbery and homicide, with a $1.5 million-dollar bail. The case was later dismissed. This led to his transition into Sun Yee On, where he became a "426 general" in 1988. He traveled back and forth between Hong Kong and New York City and was involved in karaoke bars, gambling houses, and various scams. In 1992, he was shot five times
