Li Bian
In 942, when Song Qiqiu complained that he was not given sufficient authority, Li Bian put Song in charge of overseeing the executive bureau (尚書省, "Shangshu Sheng"), while having Li Jing's younger brother Li Jingsui oversee the two other bureaus of government—the legislative (中書省, "Zhongshu Sheng") and examination (門下省, "Menxia Sheng"), with Li Jing in charge of reviewing Song's and Li Jingsui's decisions. (However, this arrangement did not last long, as, later in the year, Song's associate Xia Changtu () was accused of corruption, but Song refused to execute him. Li Bian, in anger, directly ordered Xia's execution, and after this incident, Song requested retirement and was allowed to retire.)
