New Discussion on the Form and Essence of "Shen-song Poems

In Chinese literature history, Shen-song Poems have been regarded as a sign that the design of L?shi was finalized, which isn't accurate. It took a long time for the L?shi of the Tang Dynasty to be ripe and fall into its pattern,during which four outstanding persons, who were born earlier than Shen and Song, made the greatest contribution and four literary friends of their time also played an important role. Shen and Song tried to make the L?shi structure develop in an all-round way and the metrical patterns be more precise in their writing .At the same time, the value of Shen-song Poems lies more in the lyric essence besides their form. Furthermore, in addition to L?shi, they wrote a great number of gutishi , in which their rich emotion were also expressed.
