The research on Li Ling's poems is an unsettled case in the research on the five-character poems. The intricacy lies not only in the indetermination of the poem's numbers and the complexity of its contents, but also in the particular experiences of the author Li Ling which increase the difficulty of the research in certain degrees. This paper tries to summarize the historical research on Li Ling from the angle of history, thereby deduce thc judgements of Li Ling in different periods and generalize the specific disputing situation of Li Ling's poems from the angle of literature. Through the summation of the research history of Li Ling and his poems, it is expected to find a new research angle.
