Yuen Biu is a Hong Kong martial artist. He was first enrolled in the China Drama Academy at the age of 5 (he was the youngest there). He met Sammo Hung Kam Bo and Jackie Chan while attending the Academy. Jackie Chan took him under his wing, and they became lifelong friends. He stayed at the Academy until the age of 16, when he moved with Master Jim Yuen to America. However, two years later, he came back, citing that there were no opportunities for Chinese martial artists to star in American films.

He met his wife, Phang Sau Ha, in 1984 while working as a stunt coordinator on the film. They have two children. His daughter, Yi Bui, was born in 1986, and his son, Ming Tsak, in 1988. Edit Biography
