Reading literature is very helpful for writing papers. First of all, it can help you understand the latest progress and research trends in the research field. By reading relevant literature, we can understand the research results, methods and viewpoints of other researchers in this field, thus providing reference for our own research.

This will help you choose a valuable and innovative research direction.
