1. If you already have good Korean ability, you can get a certificate of TOPIK3 level 3 or recommended level 4 or above in China. At this time, you have a better chance to apply for a Korean undergraduate course in China, but the enrollment of Korean undergraduate courses is different from that of graduate students, and more needs to be interviewed in Korea. Graduate students pass the material review, or get in touch with the professional tutor, and then pass the recommendation letter from the professor, in addition to telephone interviews.

If you are a 0-based student, I suggest you learn Korean language first, which will be faster than you are also a 0-based student in China, and this is not dumb Korean, because you will come into contact with authentic Korean in your daily life, which will also be of great help to your undergraduate course in the future.

2. Language courses in slightly better universities in South Korea, although accepting applications from China students, must be sponsored by Koreans, must be Korean nationals and have proper work certificates. If you can find such a relationship, it is willing to make such a guarantee for you. You can apply for it yourself. But there is also the risk that the visa will not pass.
