Mao Zedong attempted to fragment society by distinguishing between different sectors of society, by labeling those whose presence was a threat to Mao Zedong communist policy the Five Black Categories.
However, one part as too I'm not too sure is how did Mao Zedong act like he did towards those in the Five Black Categories. I could not find much information regarding this particular topic, as presumably most of the papers/articles discussing about this are in Chinese.
So in summary, my question is how did Mao Zedong act like he did towards those in the Five Black Categories (through the military, politically etc.). I would also really appreciate if anyone can link me research papers/articles for further reading.
