What style does Du Fu's poem Shu Xiang belong to?

Du Fu's poem "Shu Xiang" belongs to the seven laws, which was written by Du Fu in pursuit of Zhuge Liang when he was wandering in the southwest. This poem is quite unique in art: first of all, it captures the characteristics of the typical environment of the ancestral temple, renders a quiet and solemn atmosphere, and truly shows the poet's nostalgia for Zhuge Liang. The second is to give a general description of Zhuge Liang's political activities and outline the image of a promising politician. The last two sentences are remembered by future generations from Zhuge Liang's unsuccessful career, expressing his praise and regret for Zhuge Liang. These two desolate and tragic sentences are famous sentences handed down through the ages.
