The Chinese authorities have banned all public events marking the 30th anniversary of the start of the Great Proletariat Cultural Revolution (1966-76).
Yet the publication last month of the English-language edition of the definitive account on the 10 years of chaos by Yan Jiaqi and Gao Gao will once again focus international attention on the worst disaster in Communist Chinese history.
Turbulent Decade is more than a translation of the original Ten-Year History of China's 'Cultural Revolution'.
This is because the editor and translator, D.W.Y. Kwok, one of America's foremost authorities on Chinese history, has reworked the manuscript and given it a new relevance and scholarly stature.
Professor Kwok has also put together 81 pages of notes and bibliography.
When Ten-Year History first came out in 1986, it was tolerated by the relatively liberal administration of party chief Hu Yaobang.
