Wu Mingche
Initially during Emperor Fei's reign, the government was controlled by, pursuant to Emperor Wen's will, the high level officials Dao Zhongju (), Kong Huan (), Emperor Wen's brother Chen Xu, Yuan Shu (), and Liu Shizhi (). However, by spring 567, two factions were developing—one led by Chen Xu and one led by Dao and Liu, as Dao, Liu, and Chen Xu took up residence in the palace and handled most of the sensitive matters. In spring 567, Liu tried to exclude Chen Xu by having the official Yin Buning () informing Chen Xu that he should leave the palace to attend to the affairs of the capital region Yang Province (), of which Chen Xu was also governor. Chen Xu consulted Mao Xi () and Wu Mingche, both of whom persuaded him not to follow Yin's message. Wu, specifically, argued that Chen Xu was in the position of the Duke of Zhou and the Duke of Shao (uncles and regents to King Cheng of Zhou) and had a responsibility to protect the state. Chen Xu therefore invited Liu to a meeting—and while the meeting was still going on, had Mao confirming with Empress Dowager Shen and Emperor Fei that it was not their order that he leave the palace. Once Mao confirmed so, Chen Xu arrested Liu and ordered him to commit suicide, while demoting Dao to a lesser position. From this point on, the administration was controlled by Chen Xu. Dao later tried to start an uprising with the general Han Zigao (), but the plot was discovered, and Chen Xu forced both of them to commit suicide.
