In theory, there are no professional restrictions, so many candidates take advantage of the postgraduate entrance examination to change majors. Many major majors have no professional restrictions in practice. For example, many students from other majors take master's degree in economics every year. However, there are indeed some schools that do not recruit professional candidates, but generally do not publicly express it. But when the second interview, you will give a very low retest score, or simply brush it off when the second interview, you know. This depends on the personal preference of the admissions teacher. Of course, if you are confident that your professional score can be high (at least after the initial test line) and your expressive force is not bad, then you can try. It is suggested to check whether there are any successful cases of changing majors in related majors in schools in the last two years.
