The variants of references in dictionary reflect many characteristics of particular regions and era. These variants are also the key points to the research of characters’ dissemination and application. This paper based on the Access of xinzidian, reorganized all the references to Liji, and then made a comparison between the references and Liji. As a result, we found 100 variants, and summarized them as five types.　Then on this basis, we attempt to discuss the features and laws of Korea’s characters.
