先前，许远于睢阳城中积蓄资粮达六万石，虢王李巨命令分其一半，给濮阳、济阴二郡，许远坚决反对，但意见未被采纳。济阴得到粮食以后，随即连城投降了叛军，而睢阳城中的积粮此时已被吃尽。
先是，许远于城中积粮至六万石，虢王巨以其半给濮阳、济阴二郡，远固争之，不能得；既而济阴得粮，遂以城叛，而睢阳城至是食尽。
Previously, Xu Yuan had accumulated 60,000 stone of money and food in Suiyang City. Li Ju, the king of Guo, ordered to distribute half of it to the two counties of Puyang and Jiyin. Xu Yuan resolutely opposed, but his opinion was not accepted. After Jiyin obtained the food, it immediately surrendered to the rebels, and the food in Suiyang City was almost eaten up at this time.
