《元史·本纪·卷二十九》
还说 ：凡事预防于小时就容易，制止于大时就很难。你们应把我的话明告于众，使人知其所应谨慎之处。 
又曰： 凡事防之于小则易，救之于大则难，尔其以朕言明告于众，俾知所慎。 
He also said: It is easy to prevent all things when they are small, but it is difficult to stop them when they are big. You should make my words known to all so that people will know what they should be careful about.
