《魏书·帝纪·卷九》
二月十四日，皇帝下诏说： 关陇一带遭遇敌寇祸难，燕、赵一带的逆贼欺凌百姓，苍生流离，农耕失时，加上转运，劳役已经很多，州中仓库储积，不应不动，如不开出运输粮食的赏格，怎能停息漕运的烦劳。
二月丁酉，诏曰： 关陇遭罹寇难，燕赵贼逆凭陵，苍生波流，耕农靡业，加诸转运，劳役已甚，州仓储实，无宜悬匮。自非开输赏之格，何以息漕运之烦？
On February 14th, the emperor issued an edict saying: "Guanlong area has suffered misfortunes caused by the enemy, and the rebels in Yan and Zhao areas bully the people, making the common people displaced and farming out of season. In addition, transportation and labor have been too much, and the warehouses in the state should not be left idle. How can we stop the troubles of漕运 without offering rewards for transporting grain?"
