《宋史·列传·卷六十九》
到罢官回乡，二州的老百姓将杜衍阻拦在州境上，说： 为什么要调走我们贤明的太守呢？ 以太常博士提点河东路刑狱，升任尚书祠部员外郎。
及罢归，二州民邀留境上，曰： 何夺我贤太守也？ 以太常博士提点河东路刑狱，迁尚书祠部员外郎。
When Du Yan retired and went back to his hometown, the people of the two prefectures stopped him at the boundary of the prefecture, saying: “Why are you re-assigning our virtuous prefect?” He was then assigned as the Doctor of the Ministry of Imperial Officers on the Hedong circuit and then promoted to the position of Junior Officer of the Ministry of Rites.
