Abstract: Among the poets in the Song Dynasty, SU Shi was one of the most outstanding poets writing "new poems" in their works. His "new poems" were often not isolated, but had a close connection with a poet group and the certain creation mechanism. This kind of exchange of poets promoted a new writing mechanism and literary situation. His "new poems" often appears together with his "old friends", constructing vibrant poetic expression and literary scenes, and conveying the aesthetic feeling of firmness as time went by. SU Shi often mentioned "new poems" in his large number of serial versifying, forming the structure of poems in poems, which is different from the poems talking about poetry. This single or combination of several types of "new poems" made the reception and answer of serial versifying form a vivid literary ecology, and it made a deep connection between each other. Compared with other poets in the Song Dynasty, SU Shi's poetic skills were more diverse and his aesthetic style was also representative. The description of "new poems" was certainly closely related to the writing the poets he received, but also in line with the mechanism of serial versifying. "New poems" were not only general praises, but also embodies his literary ideal. In addition, "new poems" and "fresh poems" can sometimes be replaced by each other, forming a mutual text.
