是一首题画咏物诗。“雪衣公子”指“白鹭”。整首诗描绘了白鹭洁白美好、心存高洁但又孤独寂寞、无人理解的形象。首句，以“芳草”、“垂杨”、“碧流”组合成一幅春意盎然的画面，有声有色，动静结合，以优美的背景烘托白鹭美好的形象。次句，作者托物言志，通过描写白鹭的孤独、高洁的情操来表现诗人内心的孤单寂寞以及不被人理解的情感。末句，“独”、“叹”两字直抒悲、愁之情。“斜阳”以景衬情。
《一鹭图》 刘羽
芳草垂杨荫碧流，雪衣公子立芳洲。
一生清意无人识，独向斜阳叹白头。
Portrait of an Egret
Liu Yu
Through verdure among hanging willows flows shaded water,
A snow-clad prince stands at the scenic end of the river.
His lifetime purity has been recognized by no one,
He sighs over his gray hair alone in the setting son.
