《元史·列传·卷四十六》
东平至朐山，运一石米要花十石的运费，而且雨后车辆往往陷于泥淖中，不能按期送到，过期判处死刑。
东平至朐山，率十石致一石，且车淖于雨，必后期，后期罪死。
From Dongping to Qushan, transporting a dan of rice would cost ten dan for transportation cost, and if it rained, the transportation would get stuck in the mud, and it would not be able to be delivered on time, and a death penalty would be imposed if it was overdue.
