Say what you say plainly, and then take responsibility for it.

The idea to use backpacks came from my visit to Sichuan after the earthquake in May 2008. During the earthquake many schools collapsed. Thousands of young students lost their lives, and you could see bags and study material everywhere. Then you realize individual life, media, and the lives of the students are serving very different purposes. The lives of the students disappeared within the state propaganda, and very soon everybody will forget everything.

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.

Widespread state control over art and culture has left no room for freedom of expression in the country. For more than 60 years, anyone with a dissenting opinion has been suppressed. Chinese art is merely a product: it avoids any meaningful engagement. There is no larger context. Its only purpose is to charm viewers with its ambiguity.

Maybe [success] is because I'm in China and I'm more open. Maybe it's my independent behavior, or because I participated in certain projects. I have no idea.

The fantasy we had with pearls was always so luxurious and unique with a kind of rareness.

I always thought that in modern history Chinese people are like a dish of sand, never really close together. But I think a dish of sand is a good metaphor because we have the Internet. We don't have to be physically united. You can be an individual and have your own set of values but join others in certain struggles. There is nothing more powerful than that.
