Origin Story
唐朝诗人李贺，自幼聪颖，文思敏捷，但却怀才不遇。他出身于一个被贬谪的皇族，为了避免因出身受到排挤，他隐瞒了自己的身份，参加科考，做过小官。但他始终没有放弃对诗歌的热爱。他常常披星戴月，呕心沥血地创作诗歌，每一首诗都倾注了他全部的心血。他曾说：‘诗是吾之魂魄’，他把诗歌看作是自己生命的一部分。为了追求诗歌的完美，他夜以继日地读书，苦思冥想，甚至常常废寝忘食。他创作的诗歌，风格独特，想象奇特，充满浪漫主义色彩，至今仍被人们传诵。虽然他的生命短暂，但却留下了大量优秀的诗歌作品，成为中国诗歌史上的瑰宝，正是他呕心沥血的成果。
Li He, a poet of the Tang Dynasty, was intelligent and quick-witted from a young age, yet he was unlucky in his career. Born into a demoted imperial family, he concealed his identity to avoid ostracism and took the imperial examinations, eventually becoming a minor official. However, he never gave up his love for poetry. He often worked tirelessly, pouring his heart and soul into his creations, each poem imbued with his complete dedication. He once said, 'Poetry is my soul', demonstrating his deep connection to his art. In pursuit of poetic perfection, he read day and night, immersed in deep thought, often neglecting food and sleep. His poems, with their unique style, vivid imagination, and romanticism, are still admired today. Though his life was short, he left behind a rich legacy of exceptional poetry, a treasure of Chinese literary history; a testament to his relentless dedication.
