We should use this public sphere and redefine - beyond China's borders - what a government is allowed to do, where its powers end and where the realm of a citizen's privacy begins.

In the '80s, you couldn't walk in the neighborhood without looking back to see if anyone was following you. You had your key in your hand before you got to your apartment and you'd rush in so you didn't have to stop.

Everything is art. Everything is politics.

You see so many people doing quite nice and respectful work, but nobody like Warhol. Warhol is outstanding. I think he has a value that is far from fully understood. He's very special for younger generations.

I don't believe in a sense of home.

The Internet is the best thing that ever happened to China. It turns us into individuals and also enables us to share our perceptions and feelings. It creates a culture of individualism and exchange even though the real society doesn't promote it. There isn't a single Chinese university that can invite me to give a talk. Even though I know there are many students who would like to hear what I have to say.

I also doubt a man can give really clear reasons for anything.
