While gang wars are not unusual in San Francisco, perhaps the longest running ones involve tongs, which are societies or organizations within a Chinese-American community.
In the 1880s, Fung Jing Toy, nicknamed "Little Pete," created his own tong and soon gained control over Chinatown, thanks to an alliance with "Blind" Buckley, the Democrat who controlled City Hall. But after a decade in power, rival tongs banded together and offered the extravagant amount of $3,000 for Little Pete's death. On January 23, 1897, two men went into the barbershop in Little Pete's building. The tong boss was sitting in the barbershop chair, with a towel over his face, and was shot five times.
