Never look back to the past, never regret, even if there is emptiness ahead.' But I couldn't help it. Sometimes I would rather look back if it meant that I could feel something in my heart, even something sad. Sadness was better than emptiness.

There was - there still is - a big shortage of good Chinese-English literary translators. So for two years in London, I was stuck waiting, not writing, with several Chinese books I couldn't get translated. That's when I decided to write in English, since I had been living here and had decided to reconstruct my life here. Even if I wrote in broken English, it was better than getting bored and weary and bitter on the long queue of authors waiting to be translated by a stranger.

Somehow, in the novel format, I don't really like to do upfront, ideological discussion. In my heart, literature remains a poetic and ambiguous medium. On the other hand, I trained as a documentary filmmaker in film school, so my films very much reflect reality and socio-political problems. They're less subtle I would say.

I do think there will be a better understanding between the two sides - East and West. And eventually, the so-called two sides will disappear, and there will only be the conflict between those with power and those without it.

I think our literary tradition has to evolve, has to explore its form and its spirit through writers and thinkers, rather than let the lazy, easy traditional narrative - which is controlled by the publishing industry - roll all over the readers and dominate the market. I think our readers and cinemagoers have been trained to read and watch very mainstream stuff. It's like being given sleeping pills. It sends people to a non-reflective sleep state.

Self-censorship happens not only in China, or Iran or ex-Soviet places. It can happen anywhere. If an artist penetrates a certain taboo or a certain power through their work, he or she will face this problem. I'm always saying that commercial censorship is our foremost censorship globally today. Why do we still pretend we are free?
