《史记·八书·平准书》
第二年，山以东地区遭受水灾，老百姓大多陷于饥饿困乏之中，于是天子派遗使者，尽出郡国仓库中的物资赈济贫民。
其明年，山东被水灾，民多饥乏，于是天子遣使者虚郡国仓廥以振贫民。
In the second year, there was a flood in the east of the mountains. Most of the people were hungry and poor, so the emperor sent envoys to use all the resources in the counties and states to help the poor.
