Empress Cao
Empress Cao was respected by state officials, who did not oppose her to assist the Emperor in governing the state during his illnesses, and attended to state affairs by his side. In 1048, an uprising of the Imperial guards took place in her personal palace against the Emperor, and Cao was credited in saving his life. The Emperor initially blamed Cao for the uprising because it had taken place in her palace. However, he accepted the result of the following investigation, which concluded that the rumor that Cao had been behind the uprising was slander.
