《元史·列传·卷五十五》
今兴国军又遭到破坏，十分虚弱，若军民相防而不相信任，岂只担心外寇入侵，恐怕内部军民相互为敌。
今军中再经残破，单弱至此，若犹相防而不相保信，岂惟外寇可忧，第恐舟中之人皆敌国矣。
Xingguo Army has now been destroyed again, and is very weak; if the army and the common people guard against each other and do not trust one another, then there will be more than just worries about foreign enemies invading; I fear that the army and the common people within will become enemies of each other.
