Origin Story
话说东晋时期，权倾朝野的大司马桓温，在南征北战中建立了不少功勋，但他野心勃勃，一心想名垂青史。一日，他躺在床上沉思，对身边亲信说道："人生在世，总不能默默无闻吧？"亲信们噤若寒蝉。桓温又说道："一个人就算不能流芳百世，也要遗臭万年啊！"这句话后来便成了成语，用来形容那些即使死后也要留下恶名的人。桓温晚年骄横跋扈，最终不得善终。他的一生，正如他所说，虽未流芳百世，但也确实遗臭万年了。
During the Eastern Jin Dynasty, the Grand Marshal Huan Wen held immense political power. Through his military campaigns, he achieved significant victories. Despite striving to solidify his legacy, Huan Wen's ruthless ambition undermined his moral and ethical integrity, which tarnished his reputation irrevocably. His infamous words: "Even if one cannot be honored throughout the ages, one must surely be condemned forever." reflected his strong desire for fame during his lifetime and his thirst for power irrespective of the cost.
