《宋史·列传·卷二百二十五》
敌人围城一年多，地震二百多天，城中粮草耗尽，他暗中派人去河东路买粮，晚上运到城里。
贼围之岁余，地震二百余日，城中粮糗皆竭，潜遣人市籴河外，宵运以入。
The enemy besieged the city for over a year, and there were over 200 days of earthquakes, and the food supplies in the city ran out, so he secretly sent someone to He Dong Lu to buy grain, and it was transported into the city at night.
