白居易作为中唐诗坛的重要一员，有着“诗魔”的称号，江州之贬作为标志白居易创作转变的分水岭，具有显著影响。遭遇贬谪前，白居易在儒家入世精神的影响下，形成了“兼济”天下的宏愿，这在政治上表现为强烈的参政意识。他创作了大量风格激切的讽喻诗以揭示当时社会现状，为民发声， 并实现自己的政治抱负。此时白居易虽然也创作了一定数量的闲适诗，但其主旨更多是官宦生涯中的暂时休整。江州之贬后，白居易的政治生涯受挫， 尽管“兼济”思想没有彻底淡出白居易的人生，但“独善”思想逐渐成形， 并在贬谪之后成为主导思想。呈现在白居易笔下的则是与往昔截然不同的创作主题和风格格局，这时白居易的讽喻诗数量减少，风格也趋向平淡含蓄。 同时，历经种种磨难后的白居易更加深刻地理解了人生的奥义，他寄情于自然，创作出众多歌颂“知足保和，吟玩性情”的作品，从激切的讽喻转向悠然的闲适。另外，贬谪还让白居易感伤于自己的经历与人生，因此有了“感伤诗”的出现。

As an influential poet in mid-Tang, Bai Juyi, known as the "Poet of Madness," underwent a creative shift after his demotion to Jiangzhou. Initially, under Confucian influence, he aspired to "benefit all" and created incisive satirical poems to reveal societal issues. Post-demotion, his political aspirations were curbed, and though not fully abandoned, the idea of "self-perfection" emerged. His works shifted to a more subdued style, celebrating nature and the pursuit of harmony. His experiences also led to the emergence of "sentimental poems".
