John Ching Tung (Chinese: 程東) is a Hong Kong film actor and producer. He is perhaps best known for playing Cyclops in the God of Gamblers franchise as well as appearing in many Stephen Chow movies. He once told reporters, "Although I am not afraid of acting as a bad guy, there are still two roles he refuses to play. One is a rapist and the other is Japanese. I am afraid that my daughter will not understand that. I'm also afraid it will cause controversy and will be stereotyped".
