Grass on the Ancient Plain: A Farewell

I. Formal Poetic Architecture & Meter

This poem is written in the regulated five-character quatrain form (wuyan lvshi), specifically structured here as an eight-line regulated verse (wuyan paidai or wuyan lushi). It adheres strictly to the tonal meter and parallel constraints of High-to-Mid-Tang regulated verse. The rhyme scheme is level tone (pingyun), utilizing the rhyme group for 'qing' (qing, sheng, cheng, qing), creating a continuous, resonant sonic cadence that reinforces the elegiac mood of departure. The architectural spatial movement shifts smoothly from the microscopic immediacy of the grassy plain to a widening macroscopic horizon, before drawing back intimately to the immediate scene of parting.

II. Historical Chronology & Existential Impulse

Composed circa 787 during Bai Juyi's early years in Chang'an, this poem was famously written as a literary examination exercise (fu de) when the young poet was only sixteen years old. Presented to examining officials to demonstrate his command of both prosody and classical allusion, the piece instantly established his prodigious talent. Beyond its academic origin, the poem reflects the existential resilience of nature juxtaposed with the poignant fragility of human partings, a timeless theme in Tang dynasty frontier and farewell poetry.

III. Line-by-Line Exegesis & Allusion Decoding

• Lines 1-2 (Opening Couplet): The poem opens with the lush imagery of thick, luxuriant grasses stretching across the ancient plain, subject to the cyclical turning of a single year's wither and flourish. This sets a cosmic rhythm of mortality and regeneration.
• Lines 3-4 (Second Couplet): The famous pivot of the poem asserts that wild fires cannot completely consume the roots, as the vernal breezes of spring inevitably coax them back to life. This serves as a brilliant metaphor for indomitable vitality.
• Lines 5-6 (Third Couplet): The spatial perspective broadens as distant fragrances encroach upon ancient pathways, and the bright, clear verdure connects seamlessly with a desolate, ruined city wall, blending historical decay with perpetual natural renewal.
• Lines 7-8 (Closing Couplet): The concluding couplet ties the natural scene directly to human emotion, echoing the classic Chu Ci motif of sending off the noble traveler (Wangsun), while the thick, luxuriant grasses visually manifest the boundless sorrow of parting.

IV. Aesthetic Synthesis & Poetic Aftertaste

Bai Juyi achieves an extraordinary synthesis of simplicity and profound emotional resonance in this early masterpiece. By grounding the universal human pain of separation in the unyielding life force of the plain's grass, the poet elevates a conventional farewell poem into a profound meditation on endurance and renewal. The lingering aftertaste is one of bittersweet melancholy, where sorrow is tempered by the quiet certainty of cyclical rebirth.
