Dr Andrew Kwong fled famine and persecution as a child. He was a proud Maoist, singing revolutionary songs at the top of his voice at school, but then he witnessed an execution, his father was arrested, and famine struck. His family knew their only hope was to smuggle 12-year-old Andrew abroad, though it would mean years of separation. Andrew has written a book about his experience called One Bright Moon.
