《后汉书·列传·皇甫张段列传》
张奂忧愁恐惧，上书段赹说： 小人愚昧无知，得罪州将，千里托命，以情相见，您仁爱笃实，看我辛苦，我打发去您那儿的人还没有回来，又接了您的信，恩诏很清楚，前已写明。
奂忧惧，奏记谢颎曰：小人不明，得过州将，千里委命，以情相归。足下仁笃，照其辛苦，使人未反，复获邮书。
Zhang Huan was worried and fearful, and wrote to Duan Qiu, saying: "The villain is ignorant and has offended the state general. I have traveled thousands of miles to entrust my life to you and see you with my feelings. You are benevolent and honest, and you see my hard work. I haven't sent the people I sent to you yet, but I have received your letter. The imperial edict is very clear and has already been written in the front.
