The sound of snow pressing on bamboo branches in the silent night shows that the snow is increasing. The poet deliberately chose the detail of "folding bamboo" to express the word "heavy". "Folding bamboo" set off the snow from the side, with vivid image, touching twists and turns and unique feelings. The sound of "bamboo folding" sounded in the middle of the night, showing the silence of winter night, and more importantly, writing the poet's sleepless night; This is not only for the "cold pillow", but also reveals the loneliness of the poet when he lives in Jiangzhou. Because the poet reveals his unique feelings with true feelings, this poem "Snow at Night" is unique, poetic, implicit and has enduring charm.
