Matters needing attention

It is not difficult to write a summary paper. The general principle of writing is to describe the content of the article in as concise a language as possible, not in general terms. The title of the article should fully reflect the innovation and value of the article, that is to say, the most valuable content and views of the article should be reflected in the title as much as possible.

The range of topics is wide, and the topics can be big or small, as big as a field, a discipline, as small as a method and a theory, which can be determined according to their own needs. When writing a literature review for the first time, the topic should be smaller, so there are fewer documents to consult and it is easy to summarize and sort out when writing. Otherwise, the selected topic is too big, and it takes too much time to consult the literature, so it is difficult to summarize and sort it out, so that all the final conclusions are big topics or irrelevant words.
