《北史·列传·卷七十一》
王褒曾经写有《燕歌》，描绘塞北寒冷贫苦的状况维妙维肖，元帝和诸位文士一同唱和，竞相选用凄凉悲切的言词，到现在才得到验证。
褒曾作《燕歌》，妙尽塞北寒苦之状，元帝及诸文士并和之，而竞为凄切之辞，至此方验焉。
Wang Bao once wrote "Yange", profoundly depicting the frigid, poverty-ridden conditions of the Northern Territory. Emperor Yuan and all the literati joined in singing and responding, each trying to outdo each other in using desolation and grief-stricken diction.  His accounts have now proven to be true.
