The most important thing is that you must have a Korean proficiency certificate TOPIK (Advanced). In other words, if you don't have a basic knowledge of Korean, you must start studying at the Language Institute until the advanced level before you can apply for admission.
Language tuition is about 8000 RMB per semester (3 months). A year is divided into four semesters. After entering the university, if you can get a scholarship to reduce your tuition by 50%, it will be 12000 yuan/semester.
Living expenses: The living expenses in Seoul are slightly higher than those in local cities in Korea, and it costs about 50,000 yuan a year (including living expenses and accommodation). These are the basic expenses, because the consumption level varies from person to person.
I hope it helps you!
