《新唐书·列传·卷一百四十五》
这是一个办法。我赐给你国绛袍丹旗几千，装佩陈列起来。那两国见了，会认为我的军队到了，一定会退走。这是第二个办法。
我以绛袍丹帜数千赐而国，至，建以阵，二国见，谓我师至，必走，二策也。
“This is one way. I have given your country thousands of magenta robes and red flags, please display them. When the two countries see them, they will think that my army has arrived and they will surely retreat. This is the second way.”
