The general paper you are talking about is an academic paper, and its content is mainly your academic opinion on the selected topic. Literature review is mainly to summarize other people's academic views on the topic, including your evaluation of other people's academic views. Literature review is also an academic paper, but the focus is different from the general paper.

It refers to a paper written by the author aiming at a certain topic and summarizing, analyzing and refining a large number of data, materials and main viewpoints in the original research papers in a certain period. The review is three documents, with strong topic, small scope, certain depth and timeliness, which can reflect the historical background, research status and development trend of this topic.

When writing a summary, we must pay attention to some important issues:

First, the literature should be as comprehensive, cutting-edge and representative as possible. Literature review is literature, and it is a lot of literature. The reviewed literature is basically completed without literature review.

Second, to sum up and sort out, it is best to extract opinions and have an overall understanding and analysis of the topic. Literature review should not only be comprehensive, but also include comments and own opinions, not just the accumulation of literature. Review must have the author's own synthesis and induction.

Third, when writing literature review, we should pay attention to the source of quotation, and it is best to quote the original text directly to avoid indirectly quoting inappropriate documents of others and taking them out of context.
