《元史·本纪·卷二十九》
远去烟瘴地面任职，去世后不能归葬故乡，妻子儿女流离失所者，有关主管部门出资使之返还，并按旧例著为律令。
远仕瘴地，身故不得归葬，妻子流落者，有司资给遣还，仍著为令。 
For those who go far away to the land of miasma and die there, if they can't be buried in their hometown, their wives and children will be displaced. The relevant authorities will provide funds for their return and make it a rule according to the old rules.
