Abstract: Literature documents, such as All Poems of the Liao and Jin Dynasties, New Compilation of All Poems in the Jin Dynasty, All Proses of the Liao and Jin Dynasties, and Biographies of Historical Figures in the Jin Dynasty, have made outstanding contributions to the literature research of the Jin Dynasty (1115-1234) as a compilation of documents of the Jin Dynasty. However, in the research involving WANG Lei (birth or death year unknown) and other six less-known writers in Jinzhong, there are still some mistakes, such as the wrong volume number in the references, omissions of references, the incorrect information related to the year the author was born or to wrong official titles, the wrong title of a poem and the wrong line in a poem. It is necessary to list and analyze the mistakes one by one, which is conducive to scientifically make the literature research in the Jin Dynasty accurate, improve the documents of the literature in Jin Dynasty as well.
