《汉书·传·萧望之传》
只有圣明的君主亲自治理国家万事，选拔同姓，举用贤才，将他们当作心腹之人，与他们谋划政事，命令公卿大臣上朝向皇帝汇报情况，明白地说出自己的责任，来考察他们的功劳才干。
唯明主躬万机，选同姓，举贤材，以为腹心，与参政谋，令公卿大臣朝见奏事，明陈其职，以考功能。
Only the most enlightened rulers can govern the myriad affairs of the country in person, appoint members of the same family, employ men of talent, treat them as their confidants, discuss affairs of state with them, command state ministers and court officials to report to them, clearly state their responsibilities, and assess the merits of their achievements.
