李德裕歷史上宰相以辭賦書寫展開陶潛巡禮的首要案例，並以歸園書寫及其陶潛對話，展開南楚罷相期間的心靈顯影及其情志見證，不僅為唐代史學有關他此一初次罷相時期的情志脈動，提供彌補空闕的書寫扉頁；另一方面就唐代文學史或田園書寫史而言，亦提供一則別具參考價值的辭賦案例，從而映現唐代賦學與史學互涉的深層文化意蘊。

Li De Yu, as a Prime Minister, was the pioneer in the history who started to write in the form of “Ci Fu” to savor the mind of “Tao Qian.” With the writing of returning and the conversation with Tao Qian, Li De Yu reflected his mind and emotion with Tao Qian during the recall. His emotional writing during the recall did not only enrich the Historiography of Tang Dynasty, but also provide the Literary History of the Tang Dynasty and the writing history of pastoral with a “Ci Fu” case of reference value. It mirrors the deep culture meaning of intertextuality of “Fu Xue”of Tang Dynasty and Historiography.
