Origin Story
西汉时期，苏武被匈奴扣留十九年，匈奴单于多次派人劝降，其中就包括投降匈奴的汉将李陵。李陵试图以苏武的两个兄弟为例子劝降苏武，但苏武不为所动，坚守节操。最终苏武归汉，李陵送行时，心中充满了羞愧难当之情，因为他背叛了国家，而苏武却始终忠贞不渝。李陵的经历成为后世忠义与背叛的典型案例，也让人们更深刻地理解了“羞愧难当”的含义。
During the Western Han Dynasty, Su Wu was detained by the Xiongnu for nineteen years. The Xiongnu repeatedly sent people to persuade him to surrender, including Li Ling, a Han general who had defected to the Xiongnu. Li Ling attempted to persuade Su Wu to surrender by citing the example of his two brothers, but Su Wu remained unmoved, upholding his integrity. Eventually, Su Wu returned to Han, and when Li Ling saw him off, he felt overwhelming shame and remorse, for he had betrayed his country, while Su Wu had remained steadfastly loyal. Li Ling's experience became a classic example of loyalty and betrayal, helping people better understand the meaning of "overwhelming shame and remorse."
