This book recounts two deaths, the murder of Mr. Wang Jin by 31 Red Guards in the Nanjing Foreign Language School, where the senior author was a young student at the time; and the earlier murder of Mrs. Bian Zhongyun of the Girls School affiliated with the Beijing Normal University in 1966. The book is a history of two small incidents in a massive social injustice and also an attempt to understand the Cultural Revolution (CR) within the framework of modern social movement theory. The book elaborates on the sources of violence in the CR, and the definition and periodization of the CR (that is, what was it, and when did it begin and end?).
