Literature review is a writing style different from graduation thesis. Based on extensive reading and understanding of the literature in the research field involved in the topic selection, it comprehensively analyzes, summarizes and comments the research status, new level, new trends, new technologies, new discoveries and development prospects in this research field, and puts forward its own opinions and research ideas.

It requires the author not only to comprehensively sort out and state the main points of the materials he has consulted, but also to make a more professional, comprehensive, in-depth and systematic discussion and corresponding evaluation of the comprehensively sorted documents according to his own understanding and understanding, rather than just "piling up" academic research in related fields.
