I don't think it's Korean. What can I say? Now Korean refers to the language used by Koreans, including many foreign words directly translated from English. But Korean majors should teach Korean. That is, the language used by both North Korea and North Korea. But you don't have to worry. Because Chinese subjects are all the same. When you learn it well, you can use it, plus Korean intonation and vocabulary, and you can become a perfect Korean. Good luck with your studies!
