Personally, I prefer contemporary films, but the market calls for more period choices, especially since China opened up a cinema market in Hong Kong. There's a lot of restriction for contemporary films simply because of subject matter.

My action follows my characters. If a character is a cop, you cannot be posing all the time, you cannot fly off the roof because it doesn't make any sense - it's not practical.

Doing a movie is a stressful thing. You spend months of you life focusing into that one project, and I want to make sure I do something I really like or I'm really passionate about.

Action choreographer is like talking. When you talk, you have a rhythm. When you act, you have a rhythm. When you're moving your body, you have a rhythm. So as an actor, as a choreographer, the objective is trying to blend everything in - into - ultimately back into that character.

As an action director I always try to bring something fresh and new.

I don't make comparisons between any movies. I compare characters. All my actions, performances, all my films, they are driven by the characteristic. If I'm playing a cop, then I give him a particular style - I may not know that style, but as an actor I have to be responsible to do your homework and do your research and training and stuff like that.

I act according to the requirements of the character, and if I try to play the role, then I play it truthfully. In my daily life, I'm a laid-back, peaceful guy. I'm just doing my job to act.
