When using Superstar duplicate checking system, the contents of literature review are usually not included in the scope of duplicate checking. This is because literature review is to sort out, summarize and analyze the existing research literature, and it does not involve original research, nor does it require data collection and analysis such as experiments and surveys. Therefore, it does not belong to the main part of the research paper and will not be included in the duplicate checking results of the research paper.
