Over the years Woodstock got glorified and romanticised and became the event that symbolised Utopia. It's the last page of our collective memory of the age of innocence. Then things turned ugly and would never be the same again.

I try to be a partygoer. But at some point I don't know why I'm doing it and fall back. I've been using repression, the struggle between behaving as a social animal. You're seeking to be honest with your free will, less conflict. I think that's an important subject with me. That's who I am, how I was brought up. I think I use that a lot. I mistrust everything I think. Things you think you can trust, believe in, or hang on to, changes. That's the essence of life.

As artists, we like night more than day sometimes.

I think a lot of people do big movies not because they are talented artists but because they can function in the circumstances.

I look at American movies, the big muscles, and try to apply that to Chinese film-making.

I took the name Green Destiny from - well there is such a sword called Green Destiny. It is green because you keep twisting it, it's an ancient skill, you keep twisting it and knocking it and twisting it until it is very elastic and light.
