《荀子·君道》
天子配备太师、太傅、太保三公，诸侯配备一个相，大夫独掌某一官职，士谨守自己的职责，无不按照法令制度而秉公办事，这就是用来治理人的方法。
天子三公，诸侯一相，大夫擅官，士保职，莫不法度而公：是所以班治之也。
The Son of Heaven appoints the Three Dukes as Grand Preceptor, Grand Tutor, and Grand Guardian, while feudal lords appoint a single minister, high-ranking officials each oversee a single office, and scholars carefully adhere to their duties, all acting in accordance with the law and order while impartially carrying out their affairs: that is the means of governing the people.
