With the reform of higher education in China, more and more colleges and universities attach importance to the cultivation of students' ability. Therefore, elective courses can not only provide excellent academic performance of actors, but also the average level of students. Of course, students have different reasons to choose their own elective courses. Some people think that practical skills are the essence of university education, so computer science, marketing courses and finance are high priority. On the other hand, some may hold free education and elective courses on literature. Take myself for example: free education is a disciple, I stand on the concept of University, that is, not the place of survival skills, but the palace of critical knowledge and reasoning.
