Emperor Wucheng, persuaded, entrusted the civil service system to Zhao Yanshen (趙彥深), financial matters to Gao Wenyao (高文遙), the civilian administration over military affairs to Tang Yong (唐邕), and the education of Crown Prince Wei to Empress Hu's brother-in-law Feng Zicong (馮子琮) and cousin Hu Changcan (胡長璨). He himself only attended meetings with his ministers every three to four days, and he would often make short appearances and make several quick approvals and then end the meeting. When Gao Cheng's son Gao Xiaoyu (高孝瑜) tried to get him to look into He Shikai's relationship with Empress Hu, He Shikai and Gao Rui (高叡) the Prince of Zhao Commandery (Emperor Wucheng's cousin) -- whom Gao Xiaoyu had also advised Emperor Wucheng to distance himself from since Gao Rui's father Gao Chen (高琛) had died from Gao Huan's caning after he had an affair with Gao Huan's concubine Lady Erzhu—jointly accused Gao Xiaoyu falsely of plotting rebellion. In summer 563, when Emperor Wucheng received report that Gao Xiaoyu had a secret conversation with Emperor Wucheng's concubine Consort Erzhu, he poisoned Gao Xiaoyu to death.
