The adverbial phrase in the last sentence of the poem is shifted into an object.
"The human face does not know where to go, but the peach blossoms still smile in the spring breeze." "Spring Breeze" is an adverbial, which can be understood as "the peach blossoms still smile in the spring breeze." If it is really expressed in this way, it is not only that the melody is not beautiful, The meaning of poetry will also be suddenly reduced and even boring.
Using "spring breeze" as the object of "laughing" seems to be able to imagine the infatuation and ignorance of spring breeze, which seems to be better able to convey a feeling of loss about things and people. The confusion of words within a sentence goes far beyond the above-mentioned situation, because there are no preset fixed sentence patterns to choose from in poetry creation. Many smart and charming poems are temporarily generated in specific contexts.
