"The most obvious result of the Cultural Revolution, and perforce the starting point for any evaluation of the upheaval and its consequences, is that it took a fearsome toll of human lives. Of the number killed, no official count was taken at the time. Such official figures as have emerged from the post-Mao regime are fragmentary at best. The estimates of outside observers vary greatly; depending on the political proclivities of the observer. But even official statistics, however incomplete and scattered, suggest killings on a massive scale."
