In the 549 poems from the seven poetry collections, the ten-line poetry has reached 77.6%. This ratio is quite high in Siao-siao's works. The characteristics of his short poetry reveal the style of concise aesthetics. The study aims to analyze and generalize her works and points out the method of this kind of concise aesthetics. The poet often takes the exterior visual form and interior imagery as the base of the poem, i.e. the dual concision. He will use the extremely brief imagery to condense the focus of the poem in order to show the rich rhyme and beauty of the poetry. He will also remove the form of imagery or even use no imagery at all in the poem, but blend the rhyme into the abstract sensation and brief poem. As a result, the mature concise aesthetics is unfolded.
