话说唐朝时期，一位名叫李白的诗人，因其才华横溢，广受人们的敬仰。然而，朝廷中却有人嫉妒他的才华，对他进行诽谤，说他贪污受贿，中饱私囊。一时间，各种流言蜚语甚嚣尘上，李白的名声受到了极大的损害。李白面对这些莫须有的指控，感到非常气愤和无奈。为了澄清自己的名誉，他决定向朝廷上书申诉。他在书信中详细列举了自己多年来的清廉行径，并提供了确凿的证据，证明那些诽谤他的言论纯属虚构。朝廷经过仔细调查，最终查明了真相，为李白平反昭雪。李白的清白得以恢复，而那些诽谤他的人，则受到了应有的惩罚。

However, court officials, envious of his brilliance, spread slander, accusing him of bribery and embezzlement. Rumors swirled, greatly damaging Li Bai's reputation. Infuriated and frustrated by these false accusations, Li Bai decided to write to the court to clear his name. In his letter, he meticulously detailed his years of upright conduct, providing irrefutable evidence that the slander was entirely fabricated. After thorough investigation, the court uncovered the truth, exonerating Li Bai. His good name was restored, and his slanderers were duly punished.
