Da Zi Baos, were very common in China during the cultural revolution. They were a form of propaganda that Mao's followers used to humiliate "anti-revolutionaries" or to promote Mao. Da Zi Baos were often used in school environments. Ji-Li Jiang, the author of
The Red Scarf Girl had to write them when she was in school in China. For a while, all classes were canceled and the students had to write Da Zi Baos all day. Many of them were about their teachers and how they had been wronged by them. Da Zi Baos were just another way to create a division between the revolutionaries, and the citizens with a bad class status.
