China is completely lacking in self-awareness and as someone who has stepped outside that society, I have a responsibility to write about it as I see it.
I have to live within my memories, within my private universe, and continually return to China, the land where my thoughts are locked. This is a very painful kind of existence, this feeling of nowhereness.
It is vitally important for me, both personally and for my writing, to be able to return to China freely, so being barred entry has caused me deep concern and distress.
The Chinese have made a faustian pact with the government, agreeing to forsake demands for political and intellectual freedom in exchange for more material comfort. They live prosperous lives in which any expression of pain is forbidden.
'Three Kingdoms' gives you a panoply of different routes; everyone can find their own path. It shows that sometimes the route to fulfilment or success is not the obvious one. You must take twists and turns to achieve a goal.
Whatever China I'd been born into, I would probably still have become a painter - I loved sketching portraits as a child, and began art classes at the age 7. But if China hadn't been under Maoist rule, I might never have become a writer.
While I was writing 'Stick Out Your Tongue' in Beijing, the police began knocking on my door again. As soon as I finished the book, I moved to Hong Kong so that I could work undisturbed on my next novel.
In 1989, I was on Tiananmen Square with the students, living in their makeshift tents and joining their jubilant singing of the Internationale. In the two decades since, each time that I have gone back, visions from those days seem to return with increasing persistence.
The Chinese people have been forced to forget the Tiananmen massacre. There has been no public debate about the event, no official apology. The media aren't allowed to mention it. Still today people are being persecuted and imprisoned for disseminating information about it.
