The number of words in graduation thesis is 30 thousand to 50 thousand. The number of words refers to the corrected number of words, that is, the first chapter to the last chapter, excluding abstracts, tables of contents, thanks, references, appendices, etc. And it refers to the number of words rather than the number of characters. For example, a 30,000-word graduation thesis is a 30,000-word Chinese character, excluding punctuation and spaces. Master's thesis requires not only the number of words, but also the number of pages, which can be between 60 and 80 pages. This also refers to the main body of the thesis, and does not include abstract, table of contents, thanks, references and appendices. There should be no less than 40 references, including no less than 20 references in foreign languages, and no less than one third of the total references in the last five years, and the references in the last two years should be used, and the references should be cited in the paper.
