Meaning

The Master of the National Academy enters the Grand School at dawn and instructs his students: learning prospers through diligence and is wasted through play; conduct is achieved through reflection and ruined through compliance. He then declares that in this age sage rulers and worthy ministers are matched, all laws are in force, the wicked are removed and the able promoted.

国子先生早晨走进太学，召集学生们站立在学馆之下，教导他们说：学业由于勤奋而精进，由于嬉游而荒废；德行由于思考而成就，由于因循而败坏。如今圣明的君主与贤能的臣子相逢，国家的各种法令制度全都得以施行。除去凶恶奸邪的小人，进用推举才智优良的贤士。

Appreciation

A famed exhortation to learning, the piece opens with the Master's lesson 'learning thrives through diligence… conduct is accomplished through reflection,' then extols the age of 'sage and worthy meeting' and 'clear governance.' In art it blends parallel and loose prose: narration in plain sentences, the four learning maxims in antithetical pairs ('diligence–play,' 'reflection–compliance'), and the praise in crisp four-character couplets. Its emotional core is double—on the surface a teacher's exhortation, underneath Han Yu, demoted to a low post, speaks through another's mouth, coupling flattered praise of the court with hidden grievance and self-assurance, typical of the 'explication' form's 'serious words that are really ironic.' The maxim 'learning thrives through diligence…' is a perennial aphorism of study.

【白话串讲】韩愈写《进学解》：他借学生的嘴自嘲。“业精于勤，荒于嬉；行成于思，毁于随”——学业靠勤奋精进，被嬉戏荒废；德行靠思考养成，被因循毁掉——千古名言。【意象与手法】文体属“解”，源于《答客难》式的主客问答，以设问答辩展开议论。节选先叙事（晨入太学、招诸生立馆下），次发议论（业精于勤四句），再铺陈盛世（方今圣贤相逢四句），由近及远、由己及人；语言骈散相济，“业精于勤，荒于嬉；行成于思，毁于随”以“勤—嬉”“思—随”的正反对照立论，言简意赅、掷地有声。【情感与主旨】韩愈古文运动的代表作，也是“解”体文的压卷之作，以骈散相济的语言、明褒暗讽的章法，“业精于勤”成为中华劝学文化的核心格言。【名句点睛】常考“业精于勤，荒于嬉；行成于思，毁于随”以“勤—嬉”“思—随”的正反对照立论，是千古劝学格言。

Background

Han Yu (768–824), styled Tuizhi, from Heyang (present Mengzhou, Henan), known as Han of Changli, was the leader of the Tang classical-prose movement, with Liu Zongyuan called 'Han and Liu,' first of the 'Eight Great Prose Masters of the Tang and Song'; Su Shi praised him for 'reviving prose declined for eight generations, and saving the world's drowning Way.' 'Explication on the Advancement of Learning' was written during the Yuanhe era when Han Yu served as Erudite of the National Academy (c. 813); having been demoted from Secretariat clerk to this low, cold post, he modeled the piece on the question-and-answer form of Dongfang Shuo's 'Reply to a Guest's Difficulties' and Yang Xiong's 'Dispelling Ridicule,' feigning the Master instructing students, students rebutting, the Master explaining—speaking of his own grievance through another's mouth. This excerpt is the opening, stating the way of learning and describing the age's flourishing, a product of his classical revival entangled with personal circumstance: showing his zeal to lift the scholar's spirit through Confucianism, yet暗含 a jab at 'the authorities' blindness and unfairness'—grievance lodged in solemn words, self-mockery that is really self-confidence, a representative of his 'explication' prose.

韩愈（768—824），字退之，河南河阳（今河南孟州）人，郡望昌黎，世称韩昌黎，唐代古文运动的领袖，与柳宗元并称「韩柳」，列「唐宋八大家」之首，苏轼评其「文起八代之衰，道济天下之溺」。《进学解》作于唐宪宗元和年间韩愈任国子博士时（约813年），时他自职方员外郎被贬为国子博士，掌国子学，官卑位冷，郁郁不得志，遂仿东方朔《答客难》、扬雄《解嘲》的设问答辩体，假托国子先生训诲诸生、诸生反诘、先生自解，借他人之口为自己鸣不平。本文即节选国子先生晨入太学训诲诸生的开头一段，提出「业精于勤，荒于嬉；行成于思，毁于随」的为学之道，并述当世「圣贤相逢，治具毕张」的盛世景象。中唐时期，佛老盛行、骈文积弊，韩愈力倡儒学道统与古文运动，此文正是其复古主张与个人际遇交织的产物：既见其以儒学提振士风的热忱，又暗藏对「有司之不明、不公」的讥刺，牢骚寓于庄语，自嘲而实自负，是韩愈散文中「解」体文的代表作。

Art

The form belongs to the 'explication'—an ancient argumentative genre derived from the host-guest question-and-answer, unfolding argument through posed questions. Though this excerpt is only the opening lesson, it already shows full craft: first narrate (dawn entry, summon students), then argue (the four learning lines), then describe the age (sage and worthy meeting), from near to far, from self to others, orderly. In language it blends parallel and loose: the opening narrates in plain sentences; 'learning thrives through diligence…' is a neat antithesis, 'diligence–play' and 'reflection–compliance' setting the framework by contrast, terse yet weighty; from 'now sage and worthy meet' the sentences grow regular, 'the wicked rooted out, the able raised' an eight-character couplet, crisp in sound. It uses parallelism without losing the loose vigor—practice of Han Yu's 'easy and fluent' ideal and a specimen of the mid-Tang classical movement's 'turning parallel into loose, commanding words with vital energy.' As an 'explication,' its subtlety is 'open praise, hidden satire': every line flatters the sage court, every word boasts his own talent, planting the seed for the later students' challenge and the Master's reply—wanting to raise then suppress, want to suppress then raise, a circular craft worthy of a short chapter showing a great structure.

本文文体属「解」——古代的一种论说文，源于《答客难》式的主客问答，以设问答辩展开议论。节选部分虽只是开篇训辞，已尽显章法之妙：先叙事（晨入太学、招诸生立馆下），次发议论（业精于勤四句），再铺陈盛世（方今圣贤相逢四句），由近及远、由己及人，层次井然。语言上骈散相济：前段以散句叙事，明白如话；「业精于勤，荒于嬉；行成于思，毁于随」四句则骈偶工整，两两相对，以「勤—嬉」「思—随」的正反对照立论，言简意赅，掷地有声；「方今圣贤相逢，治具毕张」以下，句式渐趋整饬，「拔去凶邪，登崇畯良」八字对偶，音节铿锵。全文善用排偶而不失散行之气，是韩愈「文从字顺」主张的实践，也是中唐古文运动「变骈为散、以气驭辞」的标本。作为「解」体文，其妙还在「明褒暗讽」：句句称颂圣朝，字字自许才学，为后文诸生之诘、先生之解预埋伏笔，欲扬先抑、欲抑先扬，章法回环往复，堪称以短章见大结构。

Allusions

The 'explication' of the title derives from the 'set-argument' form since the Han—Dongfang Shuo's 'Reply to a Guest's Difficulties,' Yang Xiong's 'Dispelling Ridicule,' Ban Gu's 'Reply to a Guest's Jest' all use host-guest dialogue to voice personal feeling; Han Yu's piece is the revival of this form, its cultural lineage reaching back to the Han fu's questioning tradition. The four lines 'learning thrives through diligence…' draw on the 'Book of Documents' ('great the achievement from resolve, broad the enterprise from diligence') and the 'Analects' ('learning without thought is blindness, thought without learning is peril'), fusing pre-Qin Confucian exhortation into antithetical maxims that became perennial. 'Now sage and worthy meet, all instruments fully deployed' adapts the 'Li Ji' ideal of 'the sage taking order of the world as his task,' painting the Zhongxing atmosphere of the Zhenyuan–Yuanhe years; 'the wicked rooted out, the able raised' looks to the 'Canon of Yao' ('the worthy are in office'), 'able and good' for men of talent, describing the court's clear governance. These allusions are seamless, melting classical vocabulary into the prose—typical of Han Yu's 'tasting the finest, spilling the vast.' Culturally, the four characters 'diligence, play, reflection, compliance' sum up not only a method of study but a general Chinese philosophy of life: diligence and deep thought accomplish, play and compliance ruin—a consensus on learning and self-cultivation that transcends the age.

「进学解」之「解」，源于汉代以来的「设论」体——东方朔《答客难》、扬雄《解嘲》、班固《答宾戏》皆以主客问答自抒怀抱，韩愈此篇正是这一文体的中兴之作，故其文化血脉可上溯两汉辞赋之设问传统。「业精于勤，荒于嬉」四句，义本《尚书》「功崇惟志，业广惟勤」与《论语》「学而不思则罔，思而不学则殆」，将先秦儒家的劝学精义熔铸为对偶格言，遂成千古传诵之语。「方今圣贤相逢，治具毕张」，化用《礼记》「圣人以治天下为事」之旨，铺陈贞元、元和之际的中兴气象；「拔去凶邪，登崇畯良」，以《尚书·尧典》「俊乂在官」为远源，「畯良」犹「俊良」，指才智之士，写朝廷除邪进贤的清明政治。这些用典不露痕迹，融化经史语汇于行文之中，正是韩愈「含英咀华」「闳中肆外」的典型。从文化内涵看，「勤」「嬉」「思」「随」四字概括的，不仅是求学之法，更是中国人「业精于勤」的普遍人生哲学：勤奋与深思成就事业，嬉游与因循荒废人生，这一训辞超越时代，成为华夏文明中关于进学修身的基本共识。

Commentary

'Explication on the Advancement of Learning' is a masterpiece of Han Yu's classical movement and the finest of the 'explication' form, praised by critics since its birth. Li Han's preface to the Han collections said Han's prose 'breaks and clears like warfare'—this piece is proof of his breaking parallel ornament and clearing the style. The Qing scholar Liu Xizai's 'Artistic Outline' noted it 'imitates Reply to a Guest's Difficulties yet its literary energy is greater,' pointing to its surpassing the Han fu form. In literary history, with its parallel-loose language and praise-satire craft, it set a model for later argumentative prose; the Song writers Ouyang Xiu and Su Shi inherited its 'fit words from full energy.' In intellectual history, 'learning thrives through diligence…' became the core aphorism of Chinese exhortation culture, inspiring countless students, its influence reaching far beyond literature into educational ethics. In personal terms, it is Han Yu's self-consolation in official frustration, solemn words with hidden grievance, a model for later literati's 'crying out when wronged.' As a classic text, this excerpt compresses the whole essence of the classical movement: the调和 of parallel and loose, the melting of allusion, the circular craft, the forging of maxims—the best entry to Han Yu's style and the Tang classical movement.

《进学解》是韩愈古文运动的代表作，也是「解」体文的压卷之作，自问世以来，历代评家称赏不绝。唐人李汉《昌黎先生集序》谓韩文「摧陷廓清，比于武事」，此篇正是其摧陷骈俪、廓清文风的实证；清人刘熙载《艺概》评其「《进学解》仿《答客难》而文气更盛」，指出其对汉赋设论体的超越。从文学史看，此文以骈散相济的语言、明褒暗讽的章法，为后世论学之文确立了范式，宋代欧阳修、苏轼的议论文章，皆得其「气盛言宜」之传。从思想史看，「业精于勤，荒于嬉；行成于思，毁于随」成为中华劝学文化的核心格言，激励无数寒窗之士，其影响远超文学而深入教育伦理。从个人际遇看，此文是韩愈官场失意时的自解自嘲，以庄语写牢骚，以颂圣寓讥刺，为后世文人「不平则鸣」的书写提供了范本。作为经典课文，此节以极短的篇幅浓缩了古文运动的全部精华：骈散的调和、用典的融化、章法的回环、格言的铸造，历来是理解韩愈文风与唐代古文运动的最佳入口。

Prosody

Form Argumentative prose (the 'explication' form, imitating Han fu set-argument)论说散文（「解」体文，仿汉赋设论）

Rhyme The piece is in loose prose, unrhymed, yet strongly rhythmic, its music mainly from the repetition of parallel structures and the leading of function words. The opening narrates in loose sentences, calm in tone; 'learning thrives through diligence…' is two paired antitheses, level and oblique alternating, read crisp and ringing like metal and jade striking; 'now sage and worthy meet' and 'the wicked rooted out' advance in four-character couplets, the sound tightening, the feeling rising. Parallel and loose alternating, long and short balancing, fits Han Yu's claim that 'when energy is full, the short-long and high-low of words are all fitting.'本文为散体，不押韵，然节奏感极强，主要靠骈偶句式的复沓与虚词的领起形成声律。开篇叙事以散句行文，语气从容；「业精于勤，荒于嬉；行成于思，毁于随」四句，两两对偶、平仄相间，读来铿锵上口，如金玉相击；「方今圣贤相逢，治具毕张」「拔去凶邪，登崇畯良」再以四字对句推进，音节愈促，声情愈扬。骈散交替、长短相济，正合韩愈「气盛则言之短长与声之高下者皆宜」的主张。

Tone pattern The sentence patterns mix four-character couplets with loose sentences: narration in loose ('enters the Grand School at dawn'), argument in couplets (the four learning lines), praise also in couplets ('the wicked rooted out, the able raised'), the energy rising from calm to fervent, from teaching to praising, clearly layered. The whole opens with 'and instructs them,' the word 'instructs' setting a solemn tone befitting the Master's role.句式以四言对偶与散句交错为主：叙事处用散句（晨入太学、招诸生立馆下），议论处用对句（业精于勤四句），颂扬处亦用对句（拔去凶邪，登崇畯良），语势由平缓渐趋昂奋，由教诲转至颂扬，层次分明。全段以「诲之曰」领起训辞，一「曰」字定下庄重的语调，正与国子先生训导诸生的身份相合。

Reading note As the opening of an 'explication,' the musical beauty of this excerpt lies in the rhythm of blending parallel and loose. Han Yu, while opposing the ornate parallel of the Six Dynasties and advocating 'easy and fluent, each word in its place,' fully absorbed the sound-laws of parallelism, giving the prose music amid its varied lengths: the first three sentences are all loose, like daily narration, plain and natural; then it turns to four-character antithetical maxims, the sound suddenly bright—'learning thrives through diligence, lies waste through play; conduct is accomplished through reflection, ruined through compliance,' sixteen characters in paired antitheses, roughly level-oblique, read like beating time; then 'now,' 'rooted out,' 'raised' lead four-character clauses, the groups regular, the feeling soaring like the drumbeat of a盛世 hymn. This 'loose opening—parallel middle—regular close' layout gives the short lesson both the warmth of speech and the dignity of maxim—an early voice of Han Yu's 'prose as poetry' and a model of the classical movement's 'turning parallel into loose without abandoning sound.'作为「解」体文的开篇，《进学解》节选部分的音韵之美，集中体现在骈散相济的节奏经营上。韩愈一面力反六朝骈文的浮靡，主张「文从字顺各识职」，一面又充分吸收骈偶的声律之长，使散文在长短错落中获得音乐性：开篇三句全用散语，如日常叙事，平实自然；随即转入四字对偶的格言，音节陡亮，「业精于勤，荒于嬉；行成于思，毁于随」十六字两两相对，平仄大致相谐，读来如击节而歌；再以「方今」「拔去」「登崇」等词领起四字句，句群整齐，声情昂扬，如盛世颂歌的鼓点。这种「散起—偶承—整收」的节奏布局，使短短一段训辞既有说话的亲切，又有格言的庄严，正是韩愈「以文为诗」的先声，也是古文运动「变骈入散」而不废声律之美的典型示范。诵读此节，宜于对偶处放慢、顿挫分明，方能体会其音节与义理相得益彰之妙。

Line by line

国子先生晨入太学，招诸生立馆下，诲之曰：业精于勤，荒于嬉；行成于思，毁于随。

The Master of the National Academy enters the Grand School at dawn, summons the students to stand below the hall, and instructs them: 'Learning thrives through diligence, lies waste through play; conduct is accomplished through reflection, ruined through compliance.' (The thesis of the whole and a perennial exhortation maxim. The opening narrates the Master's diligence and authority; 'and instructs them' leads to the lesson on learning and conduct. The four clauses pair antithetically: 'learning thrives through diligence, lies waste through play' on study, 'conduct is accomplished through reflection, ruined through compliance' on conduct. The words 'thrive–waste' and 'accomplish–ruin' state the outcomes uncompromisingly—the root cause of success or failure lies in the subject's diligence or play, reflection or compliance, the very spirit of Confucian self-strengthening.)

国子先生早晨走进太学，召集学生们站立在学馆之下，教导他们说：学业由于勤奋而精进，由于嬉游而荒废；德行由于思考而成就，由于因循而败坏。

The Master of the National Academy enters the Academy at dawn, summons the students below the hall, and exhorts them: learning is perfected by diligence, neglected by play; conduct is formed by reflection, ruined by conformity.

这是全篇立论的总纲，也是千古传诵的劝学格言。开笔先叙事——「晨入太学」写国子先生的勤谨，「招诸生立馆下」写师道尊严，一晨一立之间，师者的形象已然立起；继以「诲之曰」引出训辞，由教者之「诲」带出学者之「业」与「行」。训辞四句两两相对：「业精于勤，荒于嬉」论学业，以「勤」与「嬉」对举，一正一反；「行成于思，毁于随」论德行，以「思」与「随」对举，一进一退。用「精—荒」「成—毁」四字，把进学退学的两种结局说得斩钉截铁，无一句空泛说教，全是对人生经验的凝练。妙在「嬉」「随」二字的深意：荒废学业的不是天资不足，而是嬉游放纵；败坏德行的不是环境险恶，而是随波逐流——把成败的根因归于主体的勤惰思随，正是儒家「自强不息」精神的体现，也正因如此，这四句才能超越一时一地，成为永恒的学习箴言。

This is the essay's thesis, and the famous maxim of encouragement, quoted for ages. The opening narrates — 'enters the Academy at dawn' the master's diligence, 'summons the students below the hall' the dignity of teaching, and between the dawn and the standing, the teacher's figure is already raised; then 'exhorts them' leads to the precept, the teacher's speech giving rise to the students' 'learning' and 'conduct'. The precept's four lines are paired: 'learning is perfected by diligence, neglected by play' on study, 'diligence' against 'play'; 'conduct is formed by reflection, ruined by conformity' on conduct, 'reflection' against 'conformity'. With 'perfected'—'neglected', 'formed'—'ruined', the two ends of advance and decline are stated decisively, not one word of empty sermon, all distilled from life's experience. The beauty lies in the deep meaning of 'play' and 'conformity': it is not dull wits that ruin learning, but dissolute play; not a vicious age that ruins conduct, but drifting with the tide — laying the cause of success and failure on the agent's diligence and thought, the very spirit of Confucian self-improvement, which is why these four lines outlive their time to become eternal precepts.

方今圣贤相逢，治具毕张。

Now sage and worthy meet in harmony, and all instruments of governance are fully deployed. (These two lines turn from 'instruct' to 'praise,' placing personal exhortation in the light of the age. 'Sage and worthy meet' hints at the worthy ruler and ministers; 'all instruments fully deployed' paints the political climate of the Zhenyuan–Yuanhe years. Its subtlety is 'using the age to pressure': since the age is so clear, the students have no excuse for failing, only their own want of diligence—surface praise of the age, really preparing the later warning. Against Han Yu's own demotion, the lines also hide irony: a court so clear, yet talent 'trusted by none in public, helped by none in private'—the satire lodges within the praise.)

如今圣明的君主与贤能的臣子相逢，国家的各种法令制度全都得以施行。

Now, sage ruler and able ministers meet; every institution is set in order.

这两句由「诲」转入「颂」，把个人的劝学放进时代的光照之中。「圣贤相逢」指圣君贤臣遇合，暗颂当朝天子与执政诸公；「治具毕张」写法令制度全面施行，勾勒出中唐贞元、元和之际百废俱兴的政治气象。其深意在「以时代压人」：既然圣贤相逢、治具毕张，则诸生学业不成、德行不修，便再无推诿的借口，只能归咎于自己的不勤不思——表面是颂扬盛世，实则是为下文「诸生业患不能精，无患有司之不明」的告诫张本。而结合韩愈其时被贬国子博士的处境，这两句又暗含反讽：圣朝既如此清明，贤才却「公不见信于人，私不见助于友」，言外之讥藏于颂扬之内。短短八字，既见儒家士人颂圣的传统，又见韩愈「寓庄于谐」「明褒暗讽」的章法匠心，是理解全篇「解」字深意的关键。

These two lines turn from 'exhorting' to 'praising', placing the individual's study in the light of the age. 'Sage ruler and able ministers meet' the meeting of wise sovereign and capable statesmen, discreetly praising the present court; 'every institution is set in order' the laws and measures all in force, sketching the mid-Tang air of restoration. The depth is 'pressing through the age': since sage and able meet and institutions stand, the students' imperfect learning can no longer be excused, and must be laid to their own want of diligence and thought — on the surface praise of a golden age, really preparing the ground for the later warning. And read against Han Yu's own station as a demoted professor, the lines hold a hidden irony: if the court is so clear, why are the talented 'trusted by none, helped by no friends'? The praise conceals the satire within.

拔去凶邪，登崇畯良。

The wicked and crooked are rooted out; the able and good are raised and honored. (An eight-character couplet writing the court's removal of evil and promotion of worth, the peak of the passage's praise and the seed of later satire. 'Rooted out' and 'raised' oppose, 'wicked' and 'able' contrast, crisp and ringing. It draws on the 'Canon of Yao' ('the worthy in office') and Mencius' 'promote the worthy'; 'jun' (able) is ancient-elegant for men of talent. Read with the whole, this is the height of praise—yet Han Yu himself, talented, was demoted; the fuller the praise, the deeper the satire, the celebratory surface and the cold subtext forming a huge tension. The 'Spring-Autumn brush' in Han Yu becomes 'irony spoken as praise'—these eight characters are the key to the explication's wit.)

除去凶恶奸邪的小人，进用推举才智优良的贤士。

The fierce and evil are rooted out; the worthy and excellent are raised high.

「拔去凶邪，登崇畯良」八字对偶，写朝廷的除邪进贤，是全段颂扬的收束，也是后文讥刺的伏笔。「拔去」与「登崇」对举，一除一进，一破一立；「凶邪」与「畯良」相对，一恶一善，界限分明，音节铿锵，掷地有声。其用典上承《尚书·尧典》「俊乂在官」、《孟子》「进贤」之义，「畯」通「俊」，指才智超群之士，保留古雅之词而意旨显豁。从全篇看，此句是「颂」的顶点：既然朝廷拔凶崇良、网罗贤才，那么「占小善者率以录，名一艺者无不庸」，诸生若仍不见用，只能自省不精不成；然而韩愈本人恰以才高而见黜，颂得越满，讽得越深，字面之盛与言外之冷形成巨大张力。「春秋笔法」在韩愈笔下化为「反话正说」，此八字正是读解这篇「解」体文机锋的钥匙。

'The fierce and evil are rooted out; the worthy and excellent are raised high' — eight characters in couplet, writing the court's removal of the bad and advancement of the good, the close of the praise and the seed of the satire. 'Rooted out' against 'raised high', one removal one advancement, one undoing one establishment; 'fierce and evil' against 'worthy and excellent', one bad one good, the line clear, the rhythm sonorous. The allusion carries the Book of Documents' 'the able and wise in office' and Mencius' 'advancing the worthy'; 'excellent' is the old word for the gifted. Within the essay, this is the peak of praise: since the court roots out the fierce and exalts the worthy, if the students are still unused they must blame themselves; yet Han Yu himself was cast out for high gifts — the fuller the praise, the deeper the satire, the surface splendor against the cold beneath the words. The Spring-and-Autumn method, here turned into 'saying the opposite for effect', these eight words the key to the essay's 'explanation'.

Study

Word focus

勤 Diligence. The first key word of the essay's exhortation, concentrating all of Confucianism's demands on learning attitude. 'Diligence' means labor, effort; here set against 'play,' it is the mediating variable between 'thrive' and 'waste': whether learning prospers depends not on talent but on diligence or laziness. Its scholarly root is deep: the 'Documents' ('great achievement from resolve, broad enterprise from diligence'), the 'Analects' ('learn as if you could not reach it, as if fearing to lose it'), Xunzi's 'On Learning' ('if you keep carving, even metal and stone can be opened') all take diligence as the root of advancement; Han Yu fused them into a maxim. 'Diligence' is precisely chosen: it means persistent effort, not a moment's work, contrasting with 'play' (pleasure, indulgence) on the time dimension—diligence is cumulative, play a moment's lapse. Its weight lies in condensing the plain belief 'heaven rewards diligence' into a practicable rule, hence ever-new across a thousand years. 「业精于勤」之「勤」，是全文劝学思想的第一关键词，凝聚了儒家对学习态度的全部要求。「勤」本义为辛劳、努力，此处与「嬉」对举，构成「精—荒」两极的中介变量：学业之精进与否，不系于天资高下，而系于勤惰之分。这一论断有其深远的学理渊源：《尚书》「功崇惟志，业广惟勤」、《论语》「学如不及，犹恐失之」、《荀子·劝学》「锲而不舍，金石可镂」，皆以勤勉为进学之本；韩愈以四字对偶将其熔铸为格言，遂成千古定论。从修辞看，「勤」字选得极准：它不指一时的用功，而指持久的精进，与「荒于嬉」的「嬉」（嬉游、纵乐）形成时间维度上的对照——勤是日积月累的功夫，嬉是一朝一夕的懈怠。此字之重，正在于把「天道酬勤」的朴素信念凝练成可践行的准则，故能历千年而常新。

思 Reflection. Set against 'compliance,' it is the pivotal word on conduct cultivation. 'Reflection' means thought, self-examination; here specifically the deliberate choice after reflection; 'compliance' means drifting with the crowd, parroting others. Han Yu asserts: conduct is accomplished through reflective, conscious choice, and ruined through unthinking following. This directly inherits Confucius' 'think thrice before acting' and the 'Doctrine of the Mean's' 'careful thought and clear discrimination,' raising 'reflection' from a method of knowing to the root of virtue—a literary expression of the Confucian 'unity of knowledge and action.' The contrast 'reflection–compliance' marks the line between gentleman and commoner. Later ages took 'think thrice before acting' and 'conduct accomplished through reflection' as life maxims—and Han Yu himself 'spoke frankly, fearing nothing,' a negative footnote to 'conduct accomplished through reflection': he reflected too deeply and spoke too plainly, hence this self-mocking 'Explication.' 「行成于思」之「思」，与「随」对举，是全文关于德行修养的枢纽字。「思」本义为思考、省察，此处特指对言行出处的一番深思熟虑；「随」则指随波逐流、人云亦云。韩愈断言：德行之成，在于经过思考的自觉选择；德行之毁，在于不加思索的盲目跟随。这一命题直承孔子「三思而后行」、《中庸》「慎思明辨」的传统，而把「思」从求知的方法提升为立德的根基，是儒学「知行合一」观念的文学表达。妙在「思」与「随」的对照：思是主体的、主动的，随是被动的、盲从的，一字之间，划出了君子与庸众的分界。后世以「三思而行」「行成于思」为处世箴言，可见此字影响之深远；而韩愈本人一生「发言真率，无所畏避」，正可视为「行成于思」的反面注脚——他思考得太深、说得太直，故有此《进学解》的自嘲之作。

毕张 Fully deployed. The eye of the passage's court-praise. 'Instruments of governance' refers to the laws and institutions (from Zhuangzi's 'tools for ordering the world'); 'deployed' (zhang) originally means drawing a bowstring, extended to 'put into effect, flourish'; 'fully' means all, entirely. Together they paint the thriving age where laws are spread without omission—short and forceful, echoing the dignity of 'sage and worthy meet.' Its subtlety is the word 'full': the fuller the praise, the emptier the subtext. When Han Yu wrote this he was demoted to a low post, 'trusted by none in public'—the flourishing-age description sharply contrasts his plight, praise hiding satire, exactly the 'explication' form's 'serious words that are really ironic.' In language, 'fully deployed' is ancient and terse, turning an abstract political concept into the concrete image of a drawn bowstring—showing Han Yu's craft: two characters carrying sound, sense, and feeling at once. 「治具毕张」之「毕张」，是全段颂圣文字的点睛之笔。「治具」指治国的法令制度，源出《庄子·天道》「治天下之具」；「张」本义为张开弓弦，引申为施行、振兴；「毕」表全部、尽。三字组合，写尽法令制度全面铺开、无有遗漏的盛世图景，音节短促有力，与「圣贤相逢」的雍容形成节奏上的呼应。其深意在「满」字：颂得越满，越见言外之虚。韩愈作此文时，正值自己被贬国子博士、位卑言轻之际，「治具毕张」的盛世描述与个人「公不见信于人」的窘境形成尖锐对照，颂扬之中暗含讥刺，这正是「解」体文「正言若反」的机锋所在。从语言看，「毕张」二字古雅凝练，化抽象的政治概念为具象的弓弦之象，足见韩愈炼字之工——以二字而兼声、义、情三者，非古文大家不能办。
