I was in the most restricted prison in China, the most tough. The design of the prison is modeled for internal crimes of the Communist party, so it's like a mafia family's law. It's independent to the law this nation openly applies. It's the place they take you before they give you over to the judicial system. You stay there for a year or two and they make you really suffer to confess everything.

Warhol influenced me because of his writing. If I had never read his writings and interviews, I would never have understood his work.

Warhol came from an ordinary family and he had a profound understanding about capitalism and material culture. He was probably one of the few Western artists - or artists from the United States - that could be considered a true product of his time and brought out that kind of spirit of the culture.

I'm doing quite a few things now. In one day, I will go to Kassel, Germany, for a documentary project I've been preparing for half a year. I will bring 1,001 Chinese to participate as my artwork there - any Chinese who is a Chinese passport holder and over eighteen years old could apply through my blog. I'm just bringing them to Kassel to see the art show, and pay their room and board.

The biggest obstacle in interacting with China is the difference in perspectives about basic values. These include issues such as human rights, the concept of law and constitution.

I'm not nostalgic about the old city. I don't enjoy it that much. It was just a city with one emperor and the rest of them just rats or meaningless people.

Today, we jump into this globalization of the economy and the internet age.
