梨花谢后谁识春衫袖
[lí huā xiè hòu shéi shī chūn shān xiù]
Refers to the fading beauty of life, where 'pear blossoms' represent the fleeting nature of youth or love. After they wither ('xiè'), who would remember those delicate times ('chun shan xiu'—literally the sleeve of a spring garment)? It speaks of lost beauty and remembrance.
