After rising to fame in the 1970s and '80s for his roles in martial arts films such as Knockabout, Dreadnaught, and The Prodigal Son, Biao (known alternately as Bill Yuen and Jimmy Yuen) helped Jackie Chan choreograph the action sequences for the 2000 film Shanghai Noon.
As a child, he was a star pupil and performer at the China Drama Academy. He began his film career as a stunt performer; in the early 1970s, he doubled for Bruce Lee in the martial arts film Enter the Dragon.
He appeared with Jet Li in the 1991 film Once Upon a Time in China.
He and his seven siblings grew up in Hong Kong. His marriage to Didi Pang resulted in a son named Ming-Tsak and a daughter named Yi-Bui.
During their early years, Biao and fellow martial artists Sammo Hung and Jackie Chan were part of a famous children's performance and acrobatic troupe known as the "Seven Little Fortunes."
