《明史·列传·卷二百一十七》
所派遣的使臣，一定是他的亲信心腹，现在让他们在宫殿进出，对他们毫无防备。万一奸宄之徒窥探时机，使其逆谋得逞，则后悔也来不及了。
廷议从后策，令守臣拘贡使，纵数人还，赍敕晓示祸福。
The envoys he sent must be his confidants and favored retainers. If we allow them to come and go from the palace now and remain completely unguarded, if a traitor or evil individual should take advantage of the opportunity and lead them to fulfill their treasonous plot, we will regret it too late.
