《资治通鉴·唐纪·唐纪二十九》
如今如果将司农寺的租米全部运到东都，再从东都转水路运到关中，就可以使关中稍微充实一点，假如关中有几年的储备粮，那么就不用为旱涝灾害担忧了。
今若使司农租米悉输东都，自都转漕，稍实关中，苟关中有数年之储，则不忧水旱矣。
If we now transport all the grain rent from the Ministry of Agriculture to Dongdu, and then transport it from Dongdu to Guanzhong by water, we can make Guanzhong a little more sufficient. If Guanzhong has a few years of grain reserves, then we will not have to worry about drought and flood.
