《北史·列传·卷七十》
熊安生说： 武王讨伐商纣，把纣王之首悬挂在白旗杆上，陛下平定齐国，不战而获胜利，以我的愚见，陛下的谋略为优。 
安生曰： 武王伐纣，悬首白旗；陛下平齐，兵不血刃，愚谓圣略为优。 
Xiong Ansheng said: "King Wu attacked King Zhou of Shang and hung King Zhou's head on a white flagpole. Your Majesty pacified the Qi state and won the victory without fighting. In my humble opinion, Your Majesty's strategy is better."
