In 237, Consort Guo was involved an incident that led to the death of Cao Rui's first empress (and second wife), Empress Mao. Once, when Cao Rui was attending a feast hosted by Consort Guo, Consort Guo requested that Empress Mao be invited to join as well, but Cao Rui refused and further ordered that no news about the feast was to be given to Empess Mao. However, the news leaked, and Empress Mao talked about the feast with him anyway. He became exceedingly angry, killed a number of his attendants whom he suspected of leaking the news to Empress Mao, and, inexplicably, ordered Empress Mao to commit suicide.
