201. Untitled (Hard Was Our Meeting) | Li Shangyin

颔联的伟大在于把誓言翻译成了两个生产过程：春蚕吐丝，丝（思）尽于死——爱是分泌，终身产出，至死停止；蜡炬成灰，泪（烛油）干于灰——爱是燃烧，照亮别人的同时耗尽自己。两个意象都不是修辞发明，而是唐代最常见的两种实物（养蚕与燃烛），李商隐的贡献是给它们装上了双关的引信。宋元以来，凡写至死不渝的爱情几乎都要从这一联绕行或致敬；连反对者（钱锺书嫌其「透底」）也承认它把爱情的承诺说得无路可退。一句诗成为誓言的语言上限，文学史无第二例。

The couplet's greatness is to translate a vow into two production processes: the silkworm spins its silk — longing (sī) — and stops only at death; the candle burns its tears — wax — and dries only at ash. Neither image is an invented figure; both are the commonest objects of Tang life (silk-rearing, candle-burning), and Li Shangyin's gift is the fuse of the puns. From Song to Yuan and after, every poem of love till death has had to detour past this couplet or salute it; even its critics (Qian Zhongshu thought it said too much to the bottom) concede it leaves the promise of love no retreat. For one line to become the upper limit of the language of vows — literary history offers no second case.

颈联的视角转换是这首诗最温柔的部分：诗人不在场，只能推想——她早晨对镜（愁的是鬓发改：衰老与憔悴），夜里吟诗（应觉月光寒：孤独的体感）。但愁与应觉两个词都标明这是想象：他把自己的感受安装到她身上。这种「替她过一天」的写法在技术上是移情诗的极限：不是「我想你」，而是「此刻你的镜子、你的月光我都替你承担一遍」。两句的时间（晓、夜）恰好拼成一整天——他缺席的每一天，都被这样在想象中过了一遍。

The third couplet's shift of viewpoint is the poem's tenderness: the poet absent, he can only infer — she at her morning mirror (grieving that the cloud of hair must change: age and strain), she at midnight chant (the moonlight must feel cold: the texture of solitude). But will grieve and must feel both mark the inference: he installs his own feeling into her. This living of a day on her behalf is empathy's technical limit: not I miss you but this hour's mirror, this night's moonlight, I bear them through for you. The two times, morning and night, assemble into a whole day — every day of his absence, thus lived once through in imagination.

按全诗的逻辑，结尾应该更绝望——前六句已经写到至死方休。但尾联忽然转向：蓬山此去无多路，青鸟殷勤为探看。蓬山是仙境（前一首无题里它还「一万重」远），这里却「无多路」——同一座山，两副距离。这个矛盾只能读作虚构：他明知没有路，才派一只神话里的鸟去。青鸟是西王母的信使，不必通过人间的驿站——结尾的所有希望都寄存在神话里，与现实的地理无关。这种「在虚构里修路」的写法让绝望的诗有了出口，出口通向哪儿不重要，重要的是修路这个动作本身。

By the poem's own logic the ending should darken further — six lines have already reached till death. Instead the close turns: the hills of Penglai are not so far; let the bluebird enquire for me. Penglai is fairyland (in the other Untitled poem it lay ten thousand ranges off), and here not so far — one mountain, two distances. The contradiction reads as fiction: knowing there is no road, he dispatches a bird of myth. The bluebird is the Queen Mother of the West's messenger, needing no postal relay of the human world — every hope of the ending is banked in mythology, irrelevant to real geography. This road-building inside fiction gives the despairing poem an exit; where the exit leads matters less than the act of building.
