Performing Arts in Contemporary China [PDF ebook] 

First published in 1981.The overthrow of the 'gang of four’ in October 1976 had profound effects in all areas of Chinese society, and probably nowhere can this be more clearly seen than in the performing arts. Jiang Qing, Mao Zedong’s widow, was strongly interested in the performing arts and exercised great influence over them. This book describes her influence and the effects its removal had on the arts. Although the period covered is mainly that since the death of Mao, there is also considerable reference to the years following the Cultural Revolution.
