In 559, Yuwen Hu formally returned his authorities to Emperor Ming, and Emperor Ming began to formally rule on governmental matters, but Yuwen Hu retained the command of the military. In 560, Yuwen Hu, apprehensive of Emperor Ming's abilities, had the imperial chef Li An () poison him with sugar cookies. Emperor Ming, realizing that he was near death, designated Yuwen Yong as his successor, and after he soon died, Yuwen Yong took the throne as Emperor Wu. However, the control of the government again fell into Yuwen Hu's hands.
