On the website of the Central Academy of Fine Arts, there are various enrollment brochures for advanced classes. You can apply according to your own conditions. Note that you have to apply for the exam, which means you have to pass the exam. It is said that national enrollment, undergraduate graduates can take the exam, and graduates who have worked in related fields for more than two years can also take the exam. However, most of the people admitted over the years are college teachers or people who have made certain achievements in the professional field. And the cost of further study for one year will not be less than 5w RMB (tuition plus room and board). I suggest you go to the Central American website to download some enrollment brochures from previous years, and you will know something about it.
