While on one of the latter general's campaigns, Yuan was asked to compose an official document. While leaning against his horse, he managed to complete seven pages, which led to the chengyuyǐmǎkědài (traditional Chinese: 倚馬可待; simplified Chinese: 倚马可待).[2]
Yuan is best known for his literary works, especially the Annals of the Later Han, which served as the basis for the more famous Book of Later Han by Fan Ye. An original collection of works by him, in thirty volumes, is no longer extant. Around twenty poems and essays have been preserved.
