《礼记·檀弓下》
晋国潜伏在宋国的一个探子侦探到这种情况，就回国向晋侯报告说： 阳门的一个小小卫士死了，而子罕这样的大官亲自临吊，哭得很伤心，这种作法很得民心，恐怕宋国不是好欺负的。 
晋人之觇宋者，反报于晋侯曰： 阳门之介夫死，而子罕哭之哀，而民说，殆不可伐也。 
A spy lurking in the Song Dynasty in the Jin Dynasty found out about this situation and went back to China to report to the Marquis of Jin: A small guard in Yangmen died, and such a big official as Zichan came to mourn in person and cried very sadly. This practice is very popular, I am afraid that the Song Dynasty is not easy to bully.
