"During the Cultural Revolution, people were “rebelling,” whereas before that people were "making revolution." However, after the end of the Cultural Revolution, people avoided talking about rebelling, or simply forgot that part of history. Everyone has become a victim of that great catastrophe known as the Cultural Revolution and has forgotten that before disaster fell upon their own heads, they, too, were to some extent the assailants. The history of the Cultural Revolution is thus being continually revised. It is best that you do not try to write a history, but only to look back upon your own experiences."
