I think the most important is when I was young, I learnt martial arts; that is my special key.

Zhang Yimou tried to use martial arts to talk about Chinese culture, Chinese people. What do they think, what do they want and what do they hope.

And lot of Asian audiences and reporters don't like me to act as a bad guy. But I think I want to become an actor, I want to try different way.

I think all actors want to change. When you do something many times, over and over, you want to do something fresh. But movie is still my business. A lot of action actors want change, but no studio wants to spend money on something that is not guaranteed; not proven. I think it is very difficult. It is hard to change.

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 stepped into the martial arts movie market when I was only 16. I think I have proved my ability in this field and it won't make sense for me to continue for another five or 10 years.

Everything too fast is not good but everything too slow is also not good. You need balance. That's why I like martial arts: it always tells you how to control your body, your mind, your heart. Balance. Balance can keep the world's peace. I think that's a very good thing.
