I spent a lot of time standing on street corners [of New York City] talking to local residents. I spent time in bookstores and galleries. But most of the time, I really did not have much to do.

Now I've come to such a mixed culture: America, Europe, South America, Africa. And the politics are changing everywhere all the time and becoming even more unpredictable. There's no such thing as "fixed" culture. China is also becoming more global. Its problems are becoming international problems, becoming German problems, becoming American problems. Nothing is clear-cut. Perhaps I'll find my way - or get totally lost.

We have to give our opinion, we have to say something, or we are a part of it. As an artist I am forced to say something.

China hasn't only existed for one day. Now, the whole nation has become richer and it's become a problem. The problem is universal. The factor is big. Everybody has to rethink the balance of the world and the whole landscape.

Overturning police cars is a super-intense workout. It’s probably the only sport I enjoy.

I curated this show [Shanghai Biennale ], I was by no means trying to shock people or be controversial.

Once you've tasted freedom, it stays in your heart...
