After sorting out my double-degree thesis, I decided to choose the topic in a short time and decided to write an article on the construction of margin financing and securities lending in China. By reading a lot of information on the internet and books quickly, the topic and the first draft of the paper are compared and determined. When you encounter problems related to the content of the reading materials, you should write down the outline of the materials, the views, arguments and argumentation methods that have the most profound influence on you, and write down the little experiences that come to mind. Then, we will classify, sort out and combine all the contents obtained from reading to find out and find out the problems. Materials can be classified according to the outline, such as: systematically introducing the information about the research and development of the problem; The research situation of a problem; Information about several different views on the same issue; The latest information and achievements in studying a problem, etc. Finally, compare your own experience in research and study with the data respectively, and find out which experiences are not or partially not in the data; What experience, although the information is available, but I have different views on it; What experiences and materials are basically the same; What experiences are deepened and developed on the basis of data, and so on. After several thoughtful thinking processes, it is easy to have your own ideas. Grasping this idea in time and doing further thinking will make the paper more handy.
