Shen Deqian's Anthology of Tang Poems adopts the principle of "Taking Li Bai and Du Fu as the Tenet", distinguishing his positioning of Li Bai and Du Fu's poetry from the most representative Tang poetry anthologies of previous eras. This approach emphasizes the prominence of Li Bai and Du Fu, constructing an aesthetic ideal that prioritizes Du Fu while integrating poems of both poets under the concept of their complementarity. The selection of poems by other significant poets in the Anthology of Tang Poems revolves around this aesthetic ideal. Shen Deqian paid particular attention to exploring the poetic lineage and connections between Li Bai, Du Fu, and these poets. Clarifying the specific manifestations of Shen Deqian's principle of "Taking Li Bai and Du Fu as the Tenet" in the Anthology of Tang Poems is essential to understanding how his anthology reinstates the core value of Li Bai and Du Fu in Tang poetry.
