This poem comes from "Seventeen Poems of Autumn Pu" written by Li Bai in Tang Dynasty.
Central idea: On the surface, it means the poet's lament for entering his twilight years, and on the deep, it means expressing a kind of ambivalence that there is nothing to report but he can't stop.
Appreciation: This is a magnificent autumn night 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.
