In my mind, martial arts movies are martial arts movies and action is action. It's quite different, because martial arts doesn't just have physical form; you have a philosophy, internal and external. A lot of it involves your life. How you see the world. An action film I think is just about the movement. I think it's different.

I knew nothing about martial arts. The coach told me I was talented with learning martial arts, and put me in a school. Three years later I got my first championship in China.

In martial arts, the biggest enemy is self. Inside you struggle because you want to prove something.

Working on a film, the setup for an action sequence takes a long time, and we need to shoot the scene many times to get different angles.

There is no pure success. I am action actor. I have broken almost every piece of my body.

Hero shows you how to solve the problem - yourself.

I do some of my stunts for the things I have learned. But if it is for something I have never learned, then I use a double.
