Qiupu, in the west of Guichi County, Anhui Province, was one of the producing areas of silver and copper in the Tang Dynasty. Around 753 A.D. (the 12th year of Tianbao), Li Bai wandered around here and wrote a set of poems "Song of Autumn Pu". This article is the fourteenth of them. This is a poem that describes and praises smelting workers positively. It is rare among the vast classical poems in China, so it is precious. As soon as the poem begins, it presents a smelting scene with bright colors and warm atmosphere: flaming fire, red star splashing, purple smoke transpiration, and the vast world is illuminated by red flames. The poet used two seemingly ordinary words, "Zhao" and "Luan", but once refined into poetry, it made Yejing stand out. Through this vivid scene, it is not difficult to feel the novelty, excitement and wonder of the poet. Then two sentences, "Lang night, Song moving cold Sichuan", turned to describe the image of smelting workers. With rough lines and a little outline, the poet's majestic and sturdy image of the smelter is vividly displayed on the paper. The word "Lang Lang" is novel and intriguing. "rhyme" originally refers to blushing because of shyness; Here refers to the fire reflecting the red face. From the word "Lang Lang", we can think of their strong physique and industrious, simple, enthusiastic, bold and optimistic personality. The end of the sentence "Song Dong Han Chuan" closed the characterization of the previous sentence. Smelters sing while working, and the loud singing makes the cold river ripple. What songs they sing, the poet did not specify, readers can make various supplements and associations. Song stirred up Hanchuan, of course not. This is just the poet's unique feeling, an exaggerated stroke, but extremely vivid. If the sentence "Lang Lang" only depicts the faces of smelting workers under the bright moon and fire, then this sentence reveals their inner world, their rich emotions and beautiful sentiments, and the lines are full of poets' admiration and praise. This is a magnificent autumn night smelting map. Under the poet's ingenious pen, light, heat, sound and color are intertwined, and bright and dark, cold and hot, dynamic and static are in harmony, vividly showing the fiery labor scene and vividly shaping the image of ancient smelting workers. It is indeed an artistic treasure that radiates extraordinary splendour in the treasure house of ancient poetry. [2]
