见乡人程大，

朝代：明代，
Dynasty: Ming Dynasty

作者：任原，
Author: Ren Yuan

内容：少年策马辞乡邑，落魄天涯几秋色。
Content: As a young man, I left my hometown on horseback, and after several years of wandering, the colors of autumn have passed by.

凤池昨遇故乡人，不道姓名应不识。
Yesterday at Fengchi, I met someone from my hometown, but I didn't ask his name, so I probably don't recognize him.

布衣拂却长安尘，相看感叹念情亲。
I brush off the dust of Chang'an from my humble clothes, and when we look at each other, we sigh and think of our loved ones.

青春作客无远近，白发从军多苦辛。
In our youth, we wander far and wide, and in our old age, we endure the hardships of military service, causing our hair to turn white.

以兹失路谁相顾，我向东流子南去。
In this lost path, who can we rely on? I am heading south like a drifting boat.

归梦不离沧海云，边愁远絓青枫树。
My dreams of returning home are inseparable from the vast sea of clouds, but my worries on the border are entangled like the green maple trees.

枫树丛林隔海天，百年聚散一茫然。
Maple trees in the forest separate the sea and the sky, and over a hundred years, gatherings and partings become a haze.

簪缨故旧应谁在，萍梗江湖祇自怜。
Who remains among the old friends with their hairpins and headbands? I, a lone duckweed in the rivers and lakes, can only feel pity for myself.

临歧执袂须倾倒，明朝又别关山道。
While parting at the crossroads, we hold each other's sleeves tightly, knowing we must bid farewell to the mountain pass again in the morning.

心随征雁向斜阳，悉对离忧醉芳草。
Our hearts follow the migrating geese towards the setting sun, and we drown our sorrows in the intoxicating fragrance of the grass.

诗中枫树、沧海、青枫树等意象，通过景物的隔离和聚散来象征乡愁和离愁的无常和无奈。诗人表达了对故乡和亲人的思念之情，以及在边塞漂泊生活中的孤独和自怜。

诗的最后几句表达了诗人与故乡人在别离时的相互倾诉和执别的场景，诗人借征雁归巢和醉芳草的意象，表达了内心的离愁和对归乡的向往。

整首诗以自然景物和人物形象的描绘，展现了离乡别亲、流浪漂泊的苦楚和对故乡的思念之情。同时，通过对离别、边塞生活以及年少懵懂时期的回忆，诗人抒发了对人生离合、时光流转的感慨和对自身命运的思考。
