The Shen-song Poems in Chinese literature history were not the final design of L?shi as previously thought. It took time for the L?shi structure to mature, with earlier contributors shaping its development. Shen and Song focused on refining the metrical patterns and adding lyrical essence to their poems. They also wrote gutishi to express their emotions. The value of Shen-song Poems lies not only in their form but also in their emotional depth.
