Abstract: In the late Tang Dynasty,ancient prose declined and parallel prose revived.Li Shangyin,who started with ancient prose,paid tribute to Linghu Chu,a master of parallel prose,and turned to parallel prose to help the world.However,Li Shangyin had the morality of ancient prose in his heart.His ancient prose creation is not only influenced by the essence of Han Yus ancient prose thought,but also has an independent and sober literary and moral concept and stylistic awareness.Although Li Shangyins ancient prose has few surviving articles,it involves a rich variety of styles.The texts,mainly focusing on argumentation,lyricism and human narrative,have their own characteristics.The argumentation text is sharp,the lyric text is smooth,and the human narrative writing is simple.Influenced by the concept of ancient prose,his parallel prose not only pursues the colorful stylistic essence of parallel prose in the Six Dynasties,but also integrates the elegant and positive tone of ancient prose,which is moving with emotion.Compared with the parallel prose of various schools in the late Tang Dynasty,his parallel prose is unique.

Key words: Li Shangyin, ancient prose thought, stylistic concept, parallel prose writing
