Yu Meiren is Li Yu's masterpiece and Li Houzhu's masterpiece. According to legend, on the night of his birthday (July 7th) ("Chinese Valentine's Day"), he ordered a geisha to have fun in his apartment and sang a well-known new work "Yu Meiren". Song Taizong was furious after hearing this, so he ordered people to poison his medicinal liquor. This word shows the endless sadness of a king who has died in the country in a way that contrasts the past with the present. The whole poem uses clear, concise, beautiful and fresh language, and uses various rhetorical devices such as metaphor, comparison and questioning to highly summarize and incisively express the poet's true feelings. No wonder the predecessors praised Li Yu's words as "songs of blood and tears" and "one word and one bead".
