Postgraduate graduation thesis generally requires about 30 thousand words. With formulas and charts, the text of the whole paper is generally 50 to 60 pages. If there are only a few words, formulas and charts, the number of pages will be less. In fact, the requirement of 20,000 words is not much, and the whole thesis is more than 40 pages, which is still relatively small as a master's thesis. After all, the master's thesis should reflect the workload of more than 1 year.
