 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.
