He was arrested on robbery charges in 1978, paroled in 1985, but quickly returned to crime and was sent back to prison.

Chow testified in the 2002 trial of Peter “Uncle” Chong that he was Chong’s right-hand man when Chong was head of the Wo Hop To criminal organization after Chow’s Hop Sing Tong gang merged with Chong’s to take over Chinatown’s criminal activity in 1990.

Chow is rumored to have some role in the 2006 San Francisco execution-style murder of Allen Leung , the head of Chinatown fraternal organization, a murder which remains unsolved.
