《贞观政要·卷三·论择官》
杜如晦说： 西汉和东汉选择的官员，他们的美德闻名乡里，成为众人的楷模，然后他们被州郡推荐，最后才被任用，所以两汉以选拔人才出众而著称。
如晦对曰： 两汉取人，皆行著乡闾，州郡贡之，然后入用，故当时号为多士。
Du Ruhui said: The officials selected in the Western and Eastern Han Dynasties were famous for their virtues in their hometowns, and were role models for everyone. Then they were recommended by the prefecture or county, and were then appointed, so the two Han dynasties were known for their outstanding talent selection.
