白雪歌送武判官归京

Song of White Snow in Farewell to Secretary Wu Returning to the Capital

岑参

Cen Shen

边塞frontier fortress 送别farewell 写景scenery description

北风卷地白草折，胡天八月即飞雪。
忽如一夜春风来，千树万树梨花开。
散入珠帘湿罗幕，狐裘不暖锦衾薄。
将军角弓不得控，都护铁衣冷难着。
瀚海阑干百丈冰，愁云惨淡万里凝。
中军置酒饮归客，胡琴琵琶与羌笛。
纷纷暮雪下辕门，风掣红旗冻不翻。
轮台东门送君去，去时雪满天山路。
山回路转不见君，雪上空留马行处。

Snapping the white grass, the northern wind whirls low;
In the eighth moon the Tartar sky is filled with snow.
As if the vernal breeze had come back overnight,
Adorning thousands of pear trees with blossoms white.
Snowflakes enter pearled curtains and wet the silken screen;
No warmth from furs of fox can warm us, nor quilt prove green.
The general cannot draw his rigid bow with ease;
E'en the commissioner in coat of mail would freeze.
A hundred leagues of ice spreads over frozen desert;
A thousand li of sad clouds hang o'er it in concert.
In the headquarters wine is drunk to bid adieu;
The Tartar lutes, pipas and Qiang flutes are played, anew.
At dusk heavy snow falls on camp gate with a dust;
The frozen red banner in the wind cannot flap nor rust.
At eastern gate of Luntai we bid goodbye;
On the road to Heaven's Mountain snow lies high.
I watch his horse go past a bend and, lost to sight,
His track on snow leaves me alone with heavy heart.

Meaning

The poem describes a heavy snowfall in the frontier in the eighth month, and the farewell to a colleague returning to the capital. It moves from the sudden snow and bitter cold, to the farewell feast in the camp, and finally to seeing off the traveler at Luntai's east gate, leaving only horse tracks in the snow. The scene shifts with emotion, presenting a magnificent yet desolate frontier farewell picture.

北风卷地而来，把白草生生吹折，胡地的天空才八月便已飞雪漫天。忽然像一夜春风吹过，千树万树绽开梨花般的雪白。雪花飘入珠帘打湿了罗幕，狐裘不暖，锦被也觉单薄；将军冻得角弓拉不开，都护的铁衣冰冷难穿。浩瀚沙海横亘着百丈坚冰，惨淡愁云万里凝聚不散。中军帐里摆酒为归客饯行，胡琴、琵琶与羌笛声声凄婉。黄昏大雪纷纷落满辕门，寒风扯着红旗却冻得翻不动。在轮台东门送你归去，离去时大雪铺满了天山之路。山路盘旋转过弯去再不见你的身影，雪地上只空留一行马蹄的印迹。

Appreciation

The most striking line is 'As if the vernal breeze had come back overnight, Adorning thousands of pear trees with blossoms white,' which compares winter snow to spring pear blossoms, turning bitter cold into warm beauty. 'The frozen red banner in the wind cannot flap nor rust' uses the word 'frozen' to depict extreme cold. The poem interweaves awe of frontier scenery with reluctance at parting, heroic yet tender.

【白话串讲】塞外的八月就下起大雪，岑参却把它写成“千树万树梨花开”——把苦寒写成仙境，这是边塞诗人最浪漫的想象力。诗的最后，雪还在下，送别的人却已经走远。【意象与手法】全诗以雪为线，景情相生。起笔「北风卷地」「八月飞雪」突兀奇警；「忽如」二句以浪漫想象将飞雪化作梨花，刚健中见柔美；中幅铺陈「角弓」「铁衣」「百丈冰」的酷寒，极写体感之烈；结以「雪上空留马行处」的空镜头，以景结情，余味不尽。章法上由景入事、由事入情，开阖自如。【情感与主旨】岑参两度出塞，先后任安西、北庭节度判官，长期客居西域，对边塞的奇寒与壮景体会极深。此诗于饯别席上写雪景与别情，于奇寒中见豪情，于壮景中寓深情，是盛唐边塞送别诗的气象之最。【名句点睛】常考边塞雪景送别与「忽如一夜春风来，千树万树梨花开」的奇喻——以春花喻冬雪，化凛冽为明媚，是咏雪千古名句，愁中见壮。

Background

Cen Shen twice served as a military judge in the Anxi and Beiting protectorates, experiencing frontier life deeply. This poem was written around 754 at Luntai (now Xinjiang) at a farewell banquet for Secretary Wu returning to Chang'an. It is one of the most magnificent and touching farewell poems among High Tang frontier poetry.

岑参两度出塞，先后任安西、北庭节度判官，长期客居西域，对边塞的奇寒与壮景体会极深。此诗约作于天宝十三载（754）的轮台（今新疆），是送同僚武判官归返长安的饯别席上所作，为盛唐边塞诗中气象最壮阔、情致最动人的送别之作。天宝年间，唐王朝在西域设安西、北庭两大都护府，边庭幕府文士云集，判官任满或奉命归朝者不绝于途，饯别成了幕府生活的常景。岑参天宝八载、十三载两度出塞，前后在西域度过约六年，亲历「胡天八月即飞雪」的酷寒，也亲见「风掣红旗冻不翻」的军营奇景，故能于送别之际信手拈来，将边地苦寒与壮阔风光熔铸进一席别情之中。武判官其人史传无考，当为北庭幕府同僚，岑参另有《白雪歌》系联章之作，此首独以奇喻与深情传世。全诗凡十八句，以雪起、以雪结，雪是贯穿全篇的景物主线，也是离情的底色。中唐殷璠《河岳英灵集》选岑参诗，称其「语奇体峻，意亦造奇」；清代方东树评此诗「奇峭」而有「英分绝域」之概。诗中「忽如一夜春风来，千树万树梨花开」一联，以春花喻冬雪，化凛冽为明媚，想象奇绝，遂成千古咏雪绝唱，足见盛唐人面对苦寒边塞时那种气吞山河的豪情与审美的从容。

Art

The poem uses snow as a thread, interweaving scene and feeling. It opens abruptly with the north wind and August snow; the 'spring breeze' couplet uses romantic imagination to turn snow into flowers, blending strength with grace. The middle section vividly depicts extreme cold through details like the bow and iron armor. The ending uses a blank-shot of horse tracks in the snow, lingeringly suggestive. Structurally, it moves from scene to event to emotion, freely opening and closing.

全诗以雪为线，景情相生，章法上由景入事、由事入情，开阖自如，可作盛唐歌行结构之范本。起笔「北风卷地白草折，胡天八月即飞雪」突兀奇警：「卷」「折」写风之烈，「即」字写塞北早寒来得猝然，十四个字先立起一片苦寒天地。次联「忽如一夜春风来，千树万树梨花开」是全诗最惊心动魄的转折，以浪漫想象将飞雪化作梨花，由至冷直转至美，刚健中见柔媚，愁苦中见豪迈，此即岑参诗「意亦造奇」之所在。中幅连用「散入珠帘湿罗幕」「狐裘不暖锦衾薄」「将军角弓不得控」「都护铁衣冷难着」四联，从帐内写到帐外、从衣被写到弓甲，层层铺陈酷寒，极写体感之烈；至「瀚海阑干百丈冰，愁云惨淡万里凝」，以「愁云」二字移情于景，将纯然写景转入别情的酝酿，是全篇由景入情的枢纽。后半转入饯行正题：「中军置酒饮归客」点明送别，「纷纷暮雪下辕门，风掣红旗冻不翻」以红白相映、动静相生的画面写寒极之境——旗欲翻而不得翻，正是留客之情与归客之意的写照；结以「轮台东门送君去，去时雪满天山路」「山回路转不见君，雪上空留马行处」，由送行写到望断，以「空留」的空镜头收束，景尽而情不尽，余味悠长。全诗十八句，雪景、军容、宴饮、别情四者交织，层层推宕，首尾环合，是岑参边塞歌行章法之典范。

Allusions

'In the eighth moon the Tartar sky is filled with snow' is a realistic depiction of early cold in the north. 'Adorning thousands of pear trees with blossoms white' is an original metaphor, not an allusion. 'Desert' (瀚海) originally refers to vast desert, here describing the breadth of ice. The military terms like 'headquarters' and 'camp gate' are realistic. Although lacking classical allusions, the 'pear blossom' metaphor became a model for later snow poetry.

「胡天八月即飞雪」写塞北早寒的实景，是纪实而非用典；「忽如一夜春风来，千树万树梨花开」以梨花喻雪，是化实为虚的独创巧喻，并非出于典故，却一经出手便成后世咏雪范式——中唐韩愈「白雪却嫌春色晚，故穿庭树作飞花」，晚唐温庭筠咏雪多用「盐、絮」诸喻，宋人咏雪更以「琼树」「瑶英」入句，皆从此「春雪」想象化出。「瀚海」本指浩瀚沙漠（《史记》谓霍去病封狼居胥、登临瀚海），此诗却写「百丈冰」，是将沙漠之广与冰河之坚叠合为一，以空间写奇寒；「阑干」本义纵横交错，此处写冰凌横斜之状，与李白「玉阶空伫立，宿鸟归飞急」之「阑干」用法相近，皆状纵横貌。「中军」指主帅帐幕，语出《左传》军制「三军」之制；「辕门」本指军营以车辕相向为门，此处写军营门口，皆军中实语。「胡琴琵琶与羌笛」三种乐器皆西域所出——琵琶经丝绸之路传入中原，羌笛为羌人乐器，胡琴即西域之琴，岑参罗列三种胡乐写边地宴乐，兼有《凉州词》「葡萄美酒夜光杯」式的异域色彩。全诗用典极淡，以直写、白描、奇喻胜，唯「梨花开」一喻以熟见之景写至寒之境，翻空出奇，遂成中国诗歌史上咏雪之冠。

Commentary

Yin Fan's Collection of Esteemed Poets praised Cen Shen's poetry as 'strange in language and bold in style, extraordinary in conception.' Fang Dongshu from the Qing dynasty commented this poem as 'strangely precipitous' with 'heroic and unique' quality. The 'pear blossom' metaphor became a timeless masterpiece, majestic yet tender, worthy of being the crown of High Tang frontier poetry.

殷璠《河岳英灵集》称岑参诗「语奇体峻，意亦造奇」，此诗正是「语奇」与「意奇」兼备之作；清代方东树《昭昧詹言》评其「奇峭」而有「英分绝域」之概，谓其英气横绝于绝域边庭。「忽如一夜春风来，千树万树梨花开」一联，以春花喻冬雪，一洗咏雪诗之寒苦，化凛冽为明媚，气势磅礴而情致宛转，历来选本必录，考场必考，已成「咏雪奇喻」的文化符号。全诗兼有歌行之流转与七言之整饬，转韵自如而气脉不断，是岑参边塞歌行的代表作，也是盛唐气象在边塞诗中最壮阔的一次展现。与前此高适「莫愁前路无知己，天下谁人不识君」以豪语宽慰写别不同，岑参此诗以奇寒雪景、壮阔军容写别，别情藏于雪景之中，愈写景愈见情之深，故沈德潜《唐诗别裁》谓岑参诗「于奇峭之中见雄浑」。此诗影响深远：中唐李益、晚唐卢纶写边塞雪景，皆承其奇喻一脉；宋人咏雪更以「梨花」为常语。就文学史意义而言，此诗与《走马川行》《轮台歌》并称岑参「边塞三歌」，而与高适《燕歌行》、王昌龄《出塞》共同构成盛唐边塞诗的最高峰，足称盛唐边塞之冠。

Reading note The song-style poem does not avoid rhyme changes or entering-tone rhymes. It interweaves snow description and farewell narrative, a typical structure of Cen Shen's frontier songs.此诗为七言歌行，属乐府旧题之外的新制歌行体，体制上与近体律绝迥异：不追求平仄严整与对仗工稳，而以「转韵」为章法枢纽，随情换韵、随韵换境，凡数换韵，声情与辞情高度统一。全诗以雪为脉，从起笔的屑韵入声（折、雪）写苦寒之促迫，转灰韵（来、开）写梨花奇喻之明快，再转药韵入声（薄、着）写寒侵衣甲之重，至蒸韵（冰、凝）写愁云之郁结，终以元韵（门、翻）、御韵（去、路、处）写送别之悠长，入声韵与平声韵交替，仄韵处声调短促，正合奇寒、凝愁之情；平韵处声调舒长，正合雪景、别情之旷。歌行体不避转韵，也不避以口语虚词入句，「忽如」「纷纷」「去时」等词穿插其间，如歌如叹，破板滞而生波折。这种以韵分段、以雪为经的结构，继承了汉魏乐府的转韵传统，又开了盛唐歌行（如李白《将进酒》、杜甫《兵车行》）之先声，是岑参边塞歌行章法之典范，最宜诵读。

Line by line

北风卷地白草折，胡天八月即飞雪。

The northern wind whirls low, snapping the white grass; in the Tartar sky, snow flies already in the eighth month. The verbs 'rolls' and 'snaps' emphasize the wind's ferocity; 'already' highlights the sudden extreme cold of the frontier.

北风卷地吹折白草，胡地八月便已飞雪漫天。

The north wind rolls across the ground and snaps the white grass; in the barbarian sky, snow flies already in the eighth month.

首联即写风与雪，是全诗奇寒总纲。「卷地」写风势之狂暴，自地面横扫而过；「折」写白草被生生吹断，以草之折见风之烈；「八月」点出塞北之秋而飞雪已至，一个「即」字写早寒来得猝然无备，比「早」「已」更见惊愕之态。「白草」为西域特有之草，干后色白，岑参以之写边地风物，已暗伏异域色彩。两句十字，风、雪、草、天四象并举，先声夺人，为全篇铺开一片苦寒天地的背景，亦为后文梨花奇喻蓄势——唯其写得极冷，才衬得后文写得极美。起笔即见奇寒异景，正是岑参「语奇体峻」的起手式。

The opening couplet writes at once the wind and snow, the general outline of the whole's strange cold. The words rolls across the ground write the wind's ferocity, sweeping the ground; snaps writes the white grass broken off by the blast, the grass's breaking showing the wind's fierceness; the eighth month points to the northern autumn with snow already come, and the word already writes the early cold's sudden onset, the astonishment more than early or already. The white grass is the peculiar grass of the Western Regions, white when dry; Cen Shen uses it to write the border flora, secretly laying the exotic color. The ten characters of the two lines set forth wind, snow, grass, and sky together, carrying the reader by storm, spreading a background of bitter cold, and gathering force for the later pear-blossom meta-phor - precisely because it is written so cold, the later beauty the more set off. The opening at once showing the strange cold and exotic scene is exactly Cen Shen's opening of strange words and stern form.

忽如一夜春风来，千树万树梨花开。

Suddenly, as if the spring breeze had come overnight, thousands of pear trees burst into bloom. This famous couplet uses spring blossoms to describe winter snow, turning harsh cold into radiant beauty, showing imaginative brilliance.

忽然像一夜春风吹过，千树万树绽开梨花般的雪白。

As if overnight the spring breeze had come, and on a thousand, ten thousand trees, pear blossoms opened.

这是中国诗歌史上最著名的雪喻，也是全诗诗眼。其妙有三：一在联想之奇，由雪之白、之繁、之骤，联想到梨花之白、之盛、之骤开，将寒冬飞雪转化为春风花发，化凛冽为明媚，化苦寒为壮美；二在句式之活，「忽如」二字写雪来之骤、想象之奇，如奇峰突起，「千树万树」叠用数量词，极写雪挂枝头之繁盛，仿佛一夜之间万木皆花；三在情感之壮，别人咏雪多写其寒其苦，岑参却于极寒之中看出极美，愁中见壮、苦中见豪，正是盛唐人直面苦寒而气吞山河的精神写照。此联一出，梨花遂成咏雪常语，而此联本身则成为不可复制的独创之喻，千载之下犹为绝唱。

This is the most famous snow meta-phor in Chinese poetry, and the poem's eye. Its beauty is threefold: first, the strangeness of association, from the whiteness, abundance, and suddenness of snow to the whiteness, abundance, and sudden opening of pear blossoms, turning the bleak winter snow into spring wind and flowers, the biting into the bright, the bitter cold into the magnificent; second, the life of the phrasing, the words as if overnight writing the snow's sudden coming and the strange imagination, like a peak rising abruptly, and the reduplicated thousand, ten thousand writing the snow on the boughs in abundance, as if overnight all trees flowered; third, the grandeur of feeling - others singing snow write its cold and hardship, yet Cen Shen sees the utmost beauty within the utmost cold, seeing grandeur in grief and boldness in hardship, exactly the High Tang spirit facing the bitter cold with a world-swallowing breath. Once this couplet appeared, the pear blossom became the common phrase of snow-singing, and the couplet itself the inimitable original meta-phor, still an unmatched song after a thousand ages.

散入珠帘湿罗幕，狐裘不暖锦衾薄。

It drifts through the pearl curtains and wets the silk tent; the fox fur is not warm, the bro quilt too thin.

雪花飘入珠帘打湿罗幕，狐裘不暖，锦被也觉单薄。

It drifts through the pearl curtains and wets the silk tent; the fox fur is not warm, the bro quilt too thin.

此联由室外全景转入帐内近景，写雪之细与寒之透。「散入」写雪花轻盈纷飞、随风钻入帘幕的细态，「湿」写雪化成水、沾湿罗幕的实感，一「散」一「湿」，体物入微，见岑参观察之细。下句由物写人：狐裘本为极暖之衣，却「不暖」；锦衾本为极厚之被，却觉「薄」——以贵重的狐裘锦衾尚且难御其寒，反衬塞外奇寒之甚，是加倍写法。两句一写视觉、一写体感，由外而内，由物而人，把「八月飞雪」的奇寒写得具体可触，同时帐内的温暖细物与帐外的漫天风雪形成对照，隐隐透出戍边将士的艰苦，为后文军中之景作铺垫。

This couplet turns from the outer panorama to the inner tent close-up, writing the snow's fineness and the cold's penetration. The word drifts writes the snowflakes lightly flying, threading the curtain on the wind; wets writes the snow melting and dampening the silk tent, one drift one wetness, observing things to the minute, showing Cen Shen's fine observation. The lower line turns from things to man: the fox fur, the warmest garment, yet not warm; the bro quilt, the thickest cover, yet felt thin - using the precious fox fur and bro quilt still unable to fend off the cold to set off the border's strange cold, the doubled writing. The two lines, one writing sight, one writing bodily feeling, from without to within, from things to man, writing the strange cold of the eighth-month snow concretely palpable; at the same time the tent's warm fine things and the outer sky-filling snow form a contrast, faintly revealing the hardship of the border soldiers, laying a ground for the later camp scene.

瀚海阑干百丈冰，愁云惨淡万里凝。

A hundred leagues of ice stretches across the vast desert; gloomy clouds condense for ten thousand miles. The 'gloomy clouds' project emotion onto the scene, shifting from snow description to the melancholy of farewell.

沙海横亘百丈坚冰，惨淡愁云万里凝聚不散。

The desert is crisscrossed with ice a hundred fathoms thick; gloomy, anxious clouds congeal across ten thousand li.

此联将视角再度拉远，写天地间的旷远奇寒，是全诗由景入情的枢纽。「瀚海」指浩瀚沙海，「阑干」写冰凌纵横交错之状，「百丈」极言冰层之厚，三词连用，以沙漠之广写冰封之巨，空间感极强；下句「愁云惨淡」写阴云低垂、惨淡无光，「万里凝」写愁云绵延万里、凝聚不散，时间上似已凝滞。值得玩味的是「愁云」二字：云本无情，着一「愁」字，便将天地间的惨淡气象与诗人送别的惆怅悄然接通，由纯然写景转入别情的酝酿，章法上承上启下。以天地之惨淡预衬别情，正是此联的高妙处——先写极寒之景，再点极浓之愁，景与情至此合流。

This couplet pulls the view far again, writing the vast strange cold of heaven and earth, the hinge of the whole's turning from scenery to feeling. The desert means the vast sand sea; crisscrossed writes the ice's crossing; a hundred fathoms writes the ice's thickness, the three words together using the desert's breadth to write the ice's enormity, the sense of space extreme. The lower line, gloomy, anxious clouds congeal writes the lowering dark clouds, and across ten thousand li writes the anxious clouds stretching ten thousand li, congealed, time as if frozen. What is to enjoy is the word anxious: clouds are originally passionless, yet the single word anxious quietly connects the desolate air of heaven and earth with the poet's parting melancholy, turning from pure scenery to the brewing of parting feeling, the structure carrying on above and opening below. Using the desolation of heaven and earth to preset the parting feeling is exactly the couplet's high art - first writing the utmost cold scenery, then pointing the utmost thick grief, scenery and feeling here merging.

纷纷暮雪下辕门，风掣红旗冻不翻。

At dusk, heavy snow falls on the camp gate; the wind tugs at the red flag, but it is frozen solid and cannot flutter. 'Tugs' shows the wind's force, while 'frozen' captures the extreme cold; red and white contrast vividly, creating a still-life image.

黄昏大雪落满辕门，寒风扯着红旗却冻得翻不动。

At dusk the snow falls thick at the camp gate; the wind drags the red flag, frozen past fluttering.

此联写饯别之际的军营晚景，是全诗最见炼字功力的一联。「纷纷」写暮雪密集而下，「暮」字点明黄昏时分，酒席将散、送别在即，时间的推移暗示离情的渐浓；「辕门」点出饯别之地，军营门前的画面自带边塞特有的肃穆。下句是全诗炼字之冠：「掣」字写风力拉扯之状，如生拽硬扯；「冻不翻」三字以欲动而不得动的静态写寒之至极——红旗本应猎猎翻飞，却被冻得僵直如铁。红与白相映成色，动与静相激成趣，画面如雕如刻，既见军中气象之壮，又暗合留客之意：旗欲翻而不得翻，正如归客欲留而不能留，景物之中寓情，是「不言别而别意已深」的典范。

This couplet writes the camp's dusk scene at the farewell feast, the couplet most showing the craft of refined words. The words thick write the dense falling dusk snow; the word dusk points to the evening, the feast ending and the parting at hand, the time's passing hinting the growing parting feeling; the camp gate points to the farewell place, the gate of the military camp carrying the border's peculiar solemnity. The lower line is the crown of the whole's word craft: the word drags writes the wind's pulling, as if hauling hard; frozen past fluttering writes the extreme cold through the static of wishing to move and unable - the red flag should be streaming, yet frozen stiff as iron. Red and white set off in color, motion and stillness stimulating each other in interest, the picture as if carved, at once showing the camp's grandeur and secretly matching the wish to keep the guest: the flag wishing to flutter and unable, exactly the returning guest wishing to stay and unable, feeling lodged within scenery, the model of not speaking parting yet the parting feeling already deep.

山回路转不见君，雪上空留马行处。

The mountain road twists and turns, and I no longer see you; only your horse's tracks remain in the snow. 'Only' uses the scene to convey emotion, leaving a lingering sense of loss in the empty tracks.

山路回转再不见你的身影，雪地上只空留一行马蹄印迹。

The road winds, the hills turn, and you are gone; on the snow, only the hoofprints remain.

末联以空镜头收束全篇，是唐诗写别最含蓄隽永的结尾之一。「山回路转」写归客渐行渐远，山路蜿蜒，人影转过山弯便再也望不见；「不见君」三字直写目送之久的怅惘，与王维「唯见长江天际流」同一机杼，皆以「不见」写深情。最妙在结句「雪上空留马行处」：人已不见，唯余雪地上的一行马蹄印迹，「空留」二字写人去迹存、怅然若失，以景语收情，将千言万语的别情凝于一个静默的画面之中。马蹄印终将被新雪覆盖，正如离人终将远去，惟此一瞬的凝望被诗人定格为永恒。由「送君去」到「不见君」再到「空留马行处」，三层递进，把送别之情写到极处而无一句直说，含蓄蕴藉，余味悠长。

The closing couplet closes the whole in an empty shot, one of the most reserved and lasting endings of Tang parting poetry. The road winds, the hills turn writes the returning guest going farther, the road winding, the figure passing the bend and seen no more; the words you are gone directly write the long gaze's wistfulness, the same hand as Wang Wei's I see only the Yangtze flowing to the sky, both writing deep feeling through not seeing. The finest is the closing on the snow, only the hoofprints remain: the man gone, only the line of hoofprints on the snow, the words only remain writing the man gone and the trace left, the loss, closing feeling in scenery, condensing ten thousand words of parting into a silent picture. The hoofprints will at last be covered by new snow, as the parting man will at last go far; only this instant's gaze the poet fixes as eternity. From seeing you off to you are gone to only the hoofprints remain, three layers advancing, writing the parting feeling to the utmost without a word of direct speech, reserved and stocked, the aftertone long.

Study

Word focus

忽如 'Suddenly like' – describes the abruptness of the snow and the wonder of the imagination, instantly turning bitter snow into bright spring blossoms. It is the poetic eye of the whole poem. 「忽如一夜春风来」之「忽如」二字，是全诗由实景转入奇想的枢机，亦是诗眼所在。「忽」写雪来之势骤、想象之来猝不及防；「如」字则轻轻一转，将北风飞雪的实景虚化为春风梨花的幻境。二字连用，极写联想发生之快、转折之妙：前一句还是「八月飞雪」的苦寒，下一瞬已化作千树万树的春色，其间没有任何过渡，全凭一个「忽如」横空接引，仿佛诗人面对漫天飞雪时灵光乍现、脱口而出。这个虚词以四两拨千斤之力，把至冷与至美两个极端焊接在一起，正是「意亦造奇」的枢机所在；若去此二字，则奇喻无从立足，全诗神采顿失。

掣 'Pull/tug' – depicts the wind violently pulling the red flag, but the flag is so frozen it cannot move. This word vividly conveys the extreme cold through resisted motion. 「风掣红旗冻不翻」之「掣」字，炼字如画，是盛唐边塞诗中著名的炼字之例。「掣」本义为牵引、拉拽，多用于拉车、掣肘，岑参移以写风，把无形的寒风写成有形之力，仿佛有一双巨手在生硬地拉扯红旗；而旗却被冻得僵直，任风拉扯也翻卷不动。一个「掣」字，写出了风与旗的角力：风欲动之，寒欲凝之，欲动而不得动，正见寒之至极。若换「吹」字则平，「卷」字则泛，唯「掣」字兼有力量感与受阻感，与下句「冻不翻」相激相成，动静之间，画面如雕如刻。此字一出，后世写边塞红旗者多有仿效，然终不及岑参此句的浑成。

空留 'Only remain' – the word 'only' in 'only your horse's tracks remain' expresses the emptiness after departure, using the scene to conclude the emotion with lingering resonance. 「雪上空留马行处」之「空留」二字，是全诗情感的收束点，也是中国诗歌「以景结情」技法的经典用例。「空」字写人去迹存、怅然若失：送别之际，目送友人远去，山路回转，人影已没，唯余雪地上那一行马蹄的印迹；「留」字则写这印迹是唯一残留的凭证，是这场离别在天地间留下的最后痕迹。二字合观，「空」写心理的空落，「留」写景象的残余，以有形的马蹄印写无形的失落感，把千言万语的别情凝于一个静默的镜头。马蹄印终将被风雪掩埋，正如离人终将远去天涯，惟此一瞬的凝望被诗人定格。不着一「愁」字而愁自深，不着一「别」字而别自远，含蓄蕴藉，余味悠长，正是盛唐送别诗「以景结情」的至高境界。

即 A key expression in the poem. Read it as an image, mood, or grammar point in context. 「胡天八月即飞雪」之「即」字，是全诗起笔处最见锤炼的字眼。「即」有「立即、就」之义，写八月这个本应秋高气爽的时节，塞北却已飞雪漫天，一个「即」字把边地苦寒来得猝然、毫无过渡的惊愕写得力透纸背——若是用「早」字则只写时间之提前，用「已」字则只写状态之达成，皆不及「即」字所蕴含的「不合时宜」的错愕感：八月而雪，天时乖常，人无备御，正见边塞之地的气候之异、环境之酷。「即」字又与下句「忽如」遥相呼应，一写雪之骤至，一写想象之骤转，起笔处即见岑参炼字之精、造句之奇，为全篇奇寒的基调定下第一块基石。
