晋文公之事是中国历史上著名的一段故事，讲述了晋国公爵因为犯了一个大错而被赶出国门，最终在谦让后重新得到了国家的信任和尊重。下面是晋文公之事的原文和翻译。

原文：

晋文公既失位，身为流亡之人，远离故土，惟有乘舟泛海，灰心丧气。一日，他在海上见到了一群鱼游泳，其中一只鱼似乎异常活跃。晋文公好奇地问船夫那是什么鱼，船夫回答说是鲲鱼。晋文公问这种鱼能变成什么，船夫说鲲鱼能变成鸟，飞上天空。晋文公听了感到非常惊奇，心中暗自想：“我作为一个人，失去了国家的信任和尊重，是否也能像这只鲲鱼一样，化身成为更高的存在呢？”

于是，晋文公决定放弃过去的荣耀和权力，开始重新审视自己的行为和思想，希望能够变得更加优秀和高尚。他开始学习农业、手工艺、医学和音乐等各种知识和技能，不断提高自己的素养和能力。最终，他的改变和进步得到了晋国的认可和赞赏，重新得到了公爵的地位和信任。

翻译：

After being deposed from his position as the Duke of Jin, Jin Wengong became a fugitive and left his homeland, feeling discouraged and despondent. One day, he saw a group of fish swimming in the sea, one of which seemed unusually active. Curious, Jin Wengong asked the boatman what kind of fish it was. The boatman replied that it was a Kun fish. When Jin Wengong asked if this fish could transform into anything, the boatman said that Kun fish could transform into birds and fly into the sky. Jin Wengong was amazed and wondered to himself, 'As a human being, having lost the trust and respect of my country, can I also transform into a higher being like this Kun fish?'

Therefore, Jin Wengong decided to give up his past glory and power, and began to re-examine his behavior and thoughts, hoping to become a better and more noble person. He started learning various knowledge and skills such as agriculture, handicrafts, medicine, and music, constantly improving his own literacy and ability. Eventually, his changes and progress were recognized and appreciated by the State of Jin, and he regained his position and trust as the Duke.
