The year of the Ox is approaching its end, and a heavy snowfall is falling in Yuezhong like it does in Youji. The frozen clouds have been lingering for ten days without any sign of dissipation, as they haphazardly pour down in a slanting manner, showing their immense momentum. The towering mountains are painted white with exquisite brilliance like fine pieces of pure jade and gemstones. There is no difference in color across thousands of worlds. The towering pine trees with broken branches lean over against the gorge, and the ground is covered with dead locusts hiding the ugly creatures. The world has changed direction from north to south, but there is still harmony within the cold winter weather. The white-haired elders gather to marvel at the sight, as it's truly strange and rare to see such a sight in a hundred years. Rumors say that the city is covered by snow up to three feet deep, and the narrow alleys are deeper, making it difficult to clean with a broom. Fishermen wear their bamboo-woven cloaks and get lost in their late-night return home, while children are so fascinated by the snow that they forget to sleep while reading books. Although I am cold and struggling, I feel proud and expansive as I climb up a storey and gaze at the snowy scene. I will not refuse a drink and take a sip of alcohol with my comrades, nor will I learn from Yuan An who stays indoors and stays closed off. As I am drunk and reclining on the ground, composing poems, suddenly a poem comes to me from the office of imperial secretaries. Mr. Zuo Si is both literate and martial, holding an important position in our country. His pure spirit radiates like a cold river, and he scatters these snowflakes across the earth. The evil influences of war are completely washed away by the snow, even the deepest mountains and valleys are slowly being covered by it. Therefore, we know that this is a sign of good luck from heaven, and next year will be abundant and prosperous as we remember this moment.
《次韵孙都事越中大雪歌》是一首描绘越中地区大雪盛景并寓含深意的佳作，字里行间流露出作者对自然奇观的赞叹以及对未来的美好憧憬。
开篇“庚子之岁云暮矣，越中大雪若幽蓟”，以时间背景切入，将越中的雪景与北方幽州、蓟州相比肩，瞬间将读者带入一个银装素裹的广阔世界。紧接着，“冻云十日拨不开，乱洒斜飞势容裔”，通过“冻云”与“乱洒斜飞”的描写，展现了连续多日大雪纷飞的壮观景象，雪花之态跃然纸上，既有力度又不失柔美。
“山川高下烂琼瑶，世界三千色无二”，此句将大雪覆盖下的山川比作璀璨美玉，整个世界被统一成无瑕的白色，描绘出一幅宁静而神圣的画面，让人心生敬畏。“倚壑高松折巨枝，入地遗蝗藏丑类”，一方面体现了自然之力的威猛，高松折枝；另一方面也隐含了对害虫藏匿、世间污浊被雪覆盖的净化之意。
“乾坤已回北作南，凝冱阴中有和气”，此句富含哲理，暗示着极端寒冷中孕育着生机与和谐，自然界的变化中蕴含着平衡与希望。“白头父老为咨嗟，百年睹此真奇异”，通过老人们的惊叹，反映出这场大雪的罕见与给人们心灵带来的震撼。
随后，诗人笔锋一转，从宏观转向微观：“仄闻城市三尺馀，陋巷益深难拥彗。渔翁披蓑迷晚归，童子映书忘夜寐。”这些细腻的描写，展现了大雪给日常生活带来的不便，却也勾勒出渔翁、童子等不同人物在雪中的生活剪影，平添了几分生活情趣与人文关怀。
“我虽寒苦兴自豪，一上层楼豁胸次。”诗人以自我感受入手，即便身处严寒，内心却因这壮丽雪景而豪情万丈，登高望远，心胸豁然开朗。接下来的“岂无党进酒浅斟，不学袁安户深闭”，表达了诗人不避世、乐观向上的生活态度，不愿如袁安般闭门不出，而是选择与友共饮，享受人生。
“醉酣箕踞正长吟，忽有诗从凤池至。”在醉意中吟诗正酣，意外收到来自高官的诗作，此处“凤池”象征朝廷，预示着诗文的交流超越了个人，具有了更广泛的意义。“左司先生文武兼，统制吾邦居重位。”对左司先生的赞美，不仅因其文武双全，更因其对地方的治理有着重要贡献。
“凛然清气逼银河，散此六花飞大地。”以清气比喻左司先生的高洁，而他如同天上来客，将吉祥之雪洒向人间。“兵尘沴戾尽洗空，穷谷深山亦渐被。”此句象征着大雪不仅净化了自然界的尘埃，也寓意着战乱与灾厄的平息，即便是偏远之地也能感受到这份祥和。
结尾“因知天意兆祯祥，明年大有公当记。”诗人将这场大雪视为吉祥之兆，预示着来年的丰收与国家的昌盛，同时也表达了对左司先生功绩将会被历史铭记的信心与期待。
整首诗通过对越中大雪的细腻描绘，巧妙融合了自然景观、人文关怀、哲理思考以及对未来的美好愿景，展现了诗人深邃的思想境界与高超的艺术表现力。
