Yang Su
Also in 602, Empress Dugu died. Yang Su was in charge of the funeral arrangements, and in appreciation, Emperor Wen created yet another son of Yang Su the Duke of Yikang. Upon accusations by the official Liang Pi (梁毗) that Yang Su was becoming overly powerful and abusive, Emperor Wen began to distance himself from Yang Su, although he continued to confer honors on Yang Su. The actual authority over the executive bureau was instead exercised by Su Wei and Emperor Wen's son-in-law Liu Shu (柳述).
