《史记·三十世家·晋世家》
孔子读史看到关于文公的这段记载，说： 诸侯无权召见周王。 我之所以要在《春秋》上将这件事写成 周天子在河阳打猎 ，是对此事隐讳的说法。 
孔子读史记至文公，曰： 诸侯无召王， 王狩河阳 者，《春秋》讳之也。 
Confucius read this passage about Duke Wen in history and said: The feudal lords have no right to summon the King of Zhou. The reason why I want to write this event as "The King of Heaven Zhou hunts in Heyang" in "Spring and Autumn" is to conceal it euphemistically.
