《锦瑟》是李商隐极负盛名的一首诗，也是最难索解的一首诗。诗家素有“一篇《锦瑟》解人难”的慨叹。本诗属于一首晚年回忆之作，虽然有些朦胧，却历来为人传诵。

《锦瑟》 李商隐

锦瑟无端五十弦，
一弦一柱思华年。
庄生晓梦迷蝴蝶，
望帝春心托杜鹃。
沧海月明珠有泪，
蓝田日暖玉生烟。
此情可待成追忆，
只是当时已惘然。

The Sad Zither
Li Shangyin

Why should the sad zither have fifty strings?
Each string, each strain evokes but vanished springs:
Dim morning dream to be a butterfly;
Amorous heart poured out in cuckoo’s cry.
In moonlit pearls see tears in mermaid’s eyes;
From sunburnt jade in Blue Field let smoke rise.
Such feeling cannot be recalled again:
It seemed lost even when it was felt then.
