They say that the cuisines of different Chinese provinces arose originally to serve different kinds of constituencies. Beijing was the cuisine of officials. In Shanghai, that was the cuisine of wealthy merchants and industrialists. In Szechwan, the food of the common people. Many great Szechwan dishes originated in street stalls.

You know how someone - something - surprises you. You wake up a little bit. That's done through Chinese cuisine - for example, through dishes of artifice. That's a whole sub-tradition in Chinese cuisine. To create a dish that comes to the table looking like one thing but actually is something else.

You can't portray wartime Shanghai without writing about the Holocaust - about 25,000 Jews survived the Nazi death machine by taking refuge there.

In my own life I studied music, not creative writing; I see a novel as music - an opening as an overture, themes and subplots as lines in a fugue. The chance to write a novel about a musician boxed in by all kinds of limitations but who plays out his ultimate struggle for freedom at the piano was irresistible.
