China's foremost investigative journalist Liu Binyan looks back on a century of extraordinary change. From feudalism to socialist revolution and burgeoning capitalism, China has been rocked by dramatic social and political movements, in which intellectuals were often the first victims. Talking to Isabel Hilton , Liu uses the story of his own life to examine puritanism and self-sacrifice in the Chinese psyche; Mao's manipulation of people and party; and China's place in the world.
