Raymond "Shrimp Boy" Chow is a survivor in the gangland of San Francisco's Chinatown. In 1976, the 16-year-old moved to San Francisco with his family and quickly joined the Hop Sing Boys gang. On September 4, 1977, he was at the Golden Dragon restaurant when 3 Joe Boys gang members killed 5 innocent patrons after storming the popular restaurant looking for revenge against their rivals, the Wah Ching. The attack made international news and forever changed the landscape of Chinatown's underworld. In the ensuing years, and after two stays in California's prisons, Chow's power and influence was on the rise. In 1989, he partnered with Peter Chong, a leader of the Wo Hop To triad, to first consolidate all the gangs in San Francisco's Chinatown and then expand their criminal empire nationally. Although federal and local law enforcement would bring the group down, Chow would eventually end up back on the streets of San Francisco after testifying against his former friend and partner. Raymond Chow says he is now a changed man, but only time will tell if he's given up the life of a gangster.
