Gao Wei
Due to Gao Wei's young age, Emperor Wucheng continued to be in control of major decisions, despite his "retirement." Favoring another son of his and Empress Hu's, Gao Yan (note different character than Emperor Xiaozhao) the Prince of Dongping greatly, even though Gao Yan was even younger than Gao Wei, he piled many honors and titles on Gao Yan, and Gao Yan, who was considered more intelligent and resolute than Gao Wei, at times questioned why Gao Wei was the emperor. Emperor Wucheng and Empress Hu considered deposing Gao Wei and replacing him with Gao Yan, but ultimately did not do so.
