This book is about Gu Zhun, a Chinese economist, historian and philosopher. Gu Zhun was the first person to put forward the theory of China's socialist market economy, which became a key concept in the Reform era, helping to justify the use of markets in a socialist system. He also devoted himself to the study of politics, history and philosophy, translating several foreign classic works on economics and democracy and writing a large number of articles. Due to his independent thinking and dissent, he suffered repeated political persecution, including during the Anti-Rightist Campaign and the Cultural Revolution (for more information on Gu Zhun, see his biographical entry). As he personally experienced the Anti-Rightist Campaign, the Great Famine, and the Cultural Revolution, his diary is also considered a valuable source of information on these historical events. By documenting and analyzing his life, thoughts, and the eras in which he lived, Wang's book shows how Gu Zhun persisted in his "pursuit and search for the freedom and equal rights that are inherent to all human beings " (author's preface) in an era when independent thinking was suppressed. This book was published in 2015 by the Great Mountain Culture Publishing House in Hong Kong.
