海瑞
The article was about a popular opera by Wu Han, who was deputy mayor of Beijing. Zhang Chunqiao and Jiang Qing feared the play could be counter-revolutionary because parallels could be drawn between the characters in the play and officials in the communist government. In the play, Hai Rui, a government official, speaks for the peasants against the imperial government, criticizing officials for hypocritically oppressing the masses while pretending to be virtuous men. Hai Rui is dismissed because of this. Yao claimed it was a coded attack on Mao for dismissing in 1959 then-minister of defense Peng Dehuai, a critic of Mao's Great Leap Forward.
