The 1966-76 Chinese Cultural Revolution remains one of the most catastrophic and complicated political movements of the 20th century, but strict government censorship has ensured that the era has been poorly documented. At great personal risk, journalist Li Zhensheng maintained a private archive of 20,000 photographs, 400 of which are presented here alongside Li's running diary of his experience. The images are powerful representations of a turbulent period, including photographs of unruly Red Guard rallies and Mao's rural re-education centers, as well as portraits of prominent participants in the Cultural Revolution.
