《宋史·列传·卷七十》
不久元昊让野利旺荣修书一封，这时仁宗正厌恶战争，于是对元昊进行招安安抚，派遣庞籍回报书信，叫旺荣为太尉。
既而元昊又以旺荣书来，会帝厌兵，因招怀之，遣籍报书，使呼旺荣为太尉。
Soon after, Yuanhao wrote a letter to Yeli Wangrong. At this time, Renzong was disgusted with the war, so he recruited and appeased Yuanhao, sent Pang Ji to return the letter, and asked Wang Rong to be the prime minister.
