《旧唐书·列传·卷一百二十》
 臣听说，西汉时汲黯在朝廷，逆臣淮南王不敢谋反；战国时段干木居魏国，各诸侯不敢兴兵侵犯。
臣闻汲黯在朝，淮南不敢谋叛；干木处魏，诸侯不敢加兵。
I heard that in the Western Han Dynasty, when Ji Ang was in the court, the rebellious minister King of Huainan did not dare to rebel; in the Warring States Period, when Duan Ganmu lived in Wei, other feudal states did not dare to invade.
