《虞美人·春花秋月何时了》是五代十国时期南唐后主李煜的词作。此词为作者绝笔，是一曲生命的哀歌，作者通过对自然永恒与人生无常的尖锐矛盾的对比，抒发了亡国后顿感生命落空的悲哀。全词语言明净、凝练、优美、清新，以问起，以答结，由问天、问人而到自问，通过凄楚中不无激越的音调和曲折回旋、流走自如的艺术结构，使作者沛然莫御的愁思贯穿始终，形成沁人心脾的美感效应。
The Beautiful Lady Yu : When Will the Spring Flowers and Autumn Moon End" is a poem by Li Yu, the last ruler of the Southern Tang Dynasty during the Five Dynasties and Ten Kingdoms period. This poem is the author's last work and a lament for life. The author expresses the sadness of feeling that life is empty after the country's fall through the sharp contrast between the eternity of nature and the impermanence of life. The language of the whole poem is clear, concise, beautiful and fresh. It starts with a question and ends with an answer, from asking the sky and asking people to ask oneself. Through the sad and exciting tones and the tortuous and flowing artistic structure, the author's overwhelming sorrow runs through the whole poem, forming a refreshing aesthetic effect.
