Already a veteran of the Peking Opera, he starred in countless black and white costume dramas before son Woo-Ping Yuen cast him in _Snake in Eagle's Shadow_ , the film which launched Jackie Chan's career. He then went on to feature alongside Chan and Jeong-lee Hwang(_Snake in Eagle's Shadow_'s main villain and the villain again in this film) in the sequel _Drunken Master_. These two films saw his stock rising and on the production of one film, he had to change hotels every night to avoid producers with dubious connections. He died during the filming of the Sammo Hung picture _The Magnificent Butcher_, meaning his scenes had to be re-filmed. This film was also directed by his son, who directed his last completed film _The Buddhist Fist_.
