彭真
Yao's article put Beijing Mayor Peng Zhen on the defensive. Peng, a powerful official and Wu Han's direct superior, was the head of the "Five Man Group", a committee commissioned by Mao to study the potential for a cultural revolution. Peng Zhen, aware that he would be implicated if Wu indeed wrote an "anti-Mao" play, wished to contain Yao's influence. Yao's article was initially only published in select local newspapers. Peng forbade its publication in the nationally distributed "People's Daily" and other major newspapers under his control, instructing them to write exclusively about "academic discussion," and not pay heed to Yao's petty politics. While the "literary battle" against Peng raged, Mao fired Yang Shangkun—director of the Party's General Office, an organ that controlled internal communications—on a series of unsubstantiated charges, installing in his stead staunch loyalist Wang Dongxing, head of Mao's security detail. Yang's dismissal likely emboldened Mao's allies to move against their factional rivals.
