In 1985, he made his film debut in Sammo Hung's Heart of the Dragon as one of Jackie Chan's SWAT Team buddies. He even did some doubling for superstar Chan. In 1988's Dragons Forever, Chin is seen performing the high tornado kick to Benny Urquidez in the finale. That same year, Chin replaced his brother Siu Ho in the 4th installment of Mr. Vampire. Chin has proven to be an amazing superkicker with films like Bury Me High and Operation Scorpio. After starring in The Green Hornet and Drunken Master II in 1994, he began doing non-action roles alongside action. In 1997, he directed his only film, Aces Go Places 97.
Chin once dated Lee San San, winner of the 1996 Miss Hong Kong Pageant, but they broke up. As a fan of cars and racing, he starred in a comedic short as a street racer/drifter, whether he did the driving himself, that has yet to be confirmed. However, when he took part in a 2005 TVB telethon, he performed donuts in the same 350Z as seen in the film with Lee San San standing in the center as a cone.
As of July/August 2008, the rumor is that he and Angela Tong are dating.
