嵩云秦树久离居，双鲤迢迢一纸书。
现代汉语译文
你在嵩山一带，我在秦地，我们长久地分隔两地；你从远方寄来书信，只有薄薄的一纸。
“嵩云秦树”以两地景物代指相隔的双方，也化用杜甫“渭北春天树，江东日暮云”的怀人语意。“久离居”写分别之久。“双鲤”指书信，出自汉乐府“客从远方来，遗我双鲤鱼”的典故；“迢迢”写路途遥远，“一纸书”写所寄之薄，含珍重与自谦。（“一纸书”一作“一纸笔”，今从“书”，与“双鲤”所喻的书信相合。）

休问梁园旧宾客，茂陵秋雨病相如。
现代汉语译文
不必再问当年梁园里的旧日宾客了；如今的他，就像茂陵秋雨中卧病在床的司马相如。
“梁园”是汉梁孝王的园囿，司马相如曾为座上宾客；“旧宾客”是诗人自指，暗说自己昔日也曾受令狐家礼遇。“休问”有自嘲、也有不愿多说的落寞。“茂陵”是司马相如晚年病居之地；“病相如”以相如自比，写自己多病、失意、无人过问的处境。

一封信里的旧情与近况 · Old Ties and Present Straits in One Letter
前两句回应来信：我们分隔已久，多谢你远远寄来一纸。后两句说自己的近况：不要打听我这个“旧宾客”了，我如今像茂陵秋雨里的病相如。诗人用典把自己的落魄裹起来，既谢对方念旧，又不肯直陈潦倒，分寸恰在其间。
The opening couplet answers the letter: we have long been apart, and I thank you for sending a sheet from so far. The closing couplet tells of his own state: ask no more about this old guest, for he is now the sick Xiangru in the Maoling rain. Through allusion the poet wraps up his decline—he thanks the other for remembering old ties while refusing to lay out his poverty plainly, and the balance falls exactly there.
两个典故，一层身世 · Two Allusions, One Life Story
司马相如既做过梁园宾客，又终于茂陵卧病——正好对应李商隐与令狐家的关系：早年受恩、后来疏远、如今多病失意。他不直说自己被冷落、仕途不顺，只借相如的口吻点一点。典用得贴切，怨与谢便都不必说尽。
Sima Xiangru was both a guest of the Liang Garden and a sick man at Maoling at the end—exactly matching Li Shangyin's relation to the Linghu family: favored early, estranged later, now ill and disappointed. He does not say outright that he has been neglected or that his career has stalled; he merely hints through Xiangru's voice. The allusion fits so well that neither complaint nor thanks must be spelled out.
