《文心雕龙·议对》
唐尧时期洪水造成灾难，帝尧曾向管理四方诸侯的四岳提出询问；帝舜为了举出能任百揆等官的人选，曾向群臣征求意见，确定了禹、稷、契、皋陶、伯益等五人；夏、商、周三代办事，征询意见直到打柴草的人。
洪水之难，尧咨四岳，宅揆之举，舜畴五人；三代所兴，询及刍荛。
During the reign of Emperor Yao of the Tang Dynasty, there was a flood disaster. Emperor Yao once asked the four leaders of the feudal lords, the Four Peaks, for advice. Emperor Shun, in order to select candidates for some positions such as Baigui, sought opinions from officials and decided on five people, including Yu, Ji, Qi, Gaoyao, and Boyi. During the Xia, Shang, and Zhou Dynasties, opinions were solicited even from people involved in cutting down firewood.
