Monograph refers to an in-depth and systematic research, usually conducted in academic or practical fields, aiming at solving certain problems or theories, systematically collecting, analyzing and sorting out a large number of relevant materials, data and cases, and making a comprehensive and in-depth analysis and research on the studied problems or theories.

Writing monographs requires systematic thinking ability and rich knowledge reserves. The first step in writing is to determine the research topic, research objectives and ideas. On this basis, we need to read and sort out a large number of materials and documents, and integrate and analyze the known and unknown contents in order to form our own views and conclusions. In the process of writing, we also need to pay attention to the construction of literature citation and logic to make the full text more readable and convincing.
