Postgraduates are divided into professional masters and academic masters. The former has a two-year academic system and the latter has a three-year academic system, but generally they can graduate two and a half years earlier. These two types of graduate students study classroom theory in the first year of graduate students. The former will go to the base unit for an internship for one year in the second year, while the latter will generally write graduation thesis in the school from the second year to graduation, and may participate in the tutor's project.
