> You can write more, but it's best to control it within the range of 1000 to 2000 words. The research plan, as its name implies, is the applicant's plan for the future doctoral research. In fact, it is to write down the problems you want to study and the solutions in the process of reading a PhD. < < br > > What needs to be clear is the research plan ≠ paper outline. Anyone who has written a paper knows how important an outline is. It is the basic skeleton of the paper, which determines the structure of the paper and guides the direction of the specific content of the paper. Generally speaking, if the outline of the paper can be released smoothly, the writing of the paper has actually been completed, so the difficulty of the outline can be imagined. If the research plan is the outline of the thesis, then the doctoral application is almost an impossible task, unless there are gifted academic wizards. At best, the research plan is the original low-grade version of the thesis outline. As long as in this plan, the applicant can put forward reasonable research topics and research methods and outline the main direction of research.
