Massive cerebral damage and abdominal bleeding in automobile accidents could be imitated within half an hour, aided by the application of suitable coloured resins. Convincing radiation burns required careful preparation, and might involve some three to four hours of makeup. Death, by contrast, was a matter of lying prone.

There were no museums or galleries in Shanghai, but I was very keen on art - I was always sketching and copying, and sometimes I think that my whole career as a writer has been the substitute work of an unfulfilled painter.

I don't think any particular painters have inspired me, except in a general sense. It was more a matter of corroboration. The visual arts, from Manet onwards, seemed far more open to change and experiment than the novel, though that's only partly the fault of the writers. There's something about the novel that resists innovation.

I only realised why I keep living in Shepperton when I returned to China. All the people who moved there had come from places just like Shepperton, and so they built and lived in houses exactly like these. I now know I was drawn here because, on an unconscious level, Shepperton reminds me of Shanghai.

Medicine was certainly intended to be a career. I wanted to become a psychiatrist, an adolescent ambition which, of course, is fulfilled by many psychiatrists. The doctor/psychiatrist figures in my writing are alter egos of a kind, what I would have been had I not become a writer - a personal fantasy that I've fed into my fiction.

I take for granted that for the imaginative writer, the exercise of the imagination is part of the basic process of coping with reality, just as actors need to act all the time to make up for some deficiency in their sense of themselves.
