First of all, you should have a clear theme, and then list the framework or outline. Otherwise, it's easy to get off topic, and then look for relevant literature within the outline and find more relevant articles through snowball citation. Another personal idea is to input keywords (Chinese) into Baidu to find several Chinese articles related to the theme of the review, quickly find information related to the theme, and directly find its references (foreign languages), which can save time. In addition, it is best to use your own words and add your own ideas to the useful information in the references. Earlier, my brother told me that I might be very clear about the logical relationship of the documents I wrote, but the key is to make others understand them, so I can give others reference and put forward pertinent opinions after writing them.
