唐宋八大家之一韩愈在《杂说四》中说到用人之名句:“世有伯乐,然后有千里马。千里马常有,而伯乐不常有。”伯乐,秦穆公时人,姓孙名阳,善相马之人。人称:“伯乐,一过冀北之野,而马群遂空。”意即良马都被选走,而且是“伯乐一顾,价增三倍”。这说明伯乐真是一个识货的人。 Han Yu, one of the eight Tang and Song dynasties, said in Quarrel Four: “There are horses in the world, and then there are Maxima. Maxima often, and Bole is not often.” “Bole, Qin Mu public man, surnamed Sun Ming Yang , Good people horse. People say: ”Bole, a field of northern Hebei, and the horses are empty.“ That means all the good horses have been chosen to go, and is ”Bole look, price increase three times." This shows that Bole is really a man of knowledge.
