Our defense begins with a three-minute self-introduction, that is, a brief introduction of ourselves, and then your paper. We basically said it according to the summary. After the self-report, the teacher asks questions and you answer them. The teacher's questions are all based on your paper. When defending, the teacher didn't have time to look carefully. Usually he will ask questions according to your catalogue. You should study your catalogue carefully first. With your topic, if it is a simple question, you may mention the reasons why Koreans study in China, and why do you want to study this.
