Zheng Chaolin helped found the Chinese Communist Party's European branch in Paris in 1922 and its Trotskyist Opposition in Shanghai in 1931. He held the world record in political imprisonment - seven years under Chiang Kai-shek (as a revolutionary) and 27 under Mao (as a 'counterrevolutionary'), thus beating by a year Auguste Blanqui's previous record. After joining the revolution in his teens, his commitment never wavered. Born in 1901, he died in 1998, so his life was coterminous with the century and a dramatic embodiment of its vicissitudes. This book is record of his contribution to revolutionary thought in China.
