Gao Wei
Gao Wei was considered a young man of weak personality, and while Gao Wei was emperor, Emperor Wucheng and Retired Empress Hu both greatly favored his younger brother, Gao Yan the Prince of Dongping, honoring Gao Yan with many high offices and making sure that Gao Yan received all of the same supplies as his emperor brother did. Gao Yan was considered intelligent and decisive, and he once asked Emperor Wucheng, "My brother is weak in personality. How can he lead the empire?" Both Emperor Wucheng and Retired Empress Hu considered deposing Gao Wei and making Gao Yan emperor, but did not actually do so.
