This metaphor, which takes the sky as the noumenon and sapphire as the metaphor, compares the sky to an overwhelming sapphire, polished by the autumn wind, and fully shows the characteristic phenomenon of Ming Che in crisp autumn. The so-called crisp autumn, that's all.
Anthropomorphic sentence: I don't know if the maple leaves in the valley are drunk or if they show infinite enthusiasm for autumn. Otherwise, why are they as red as flames?
This anthropomorphic sentence imitates the maple leaf as a person, like the face of a drunk person, or blushes with enthusiasm. It is not so much "enthusiasm" and "drunkenness" as maple leaves, such as the author himself, which expresses the author's thoughts and feelings of loving autumn and being drunk in autumn.
