It is really an unpopular major. I am a graduate student in the School of Electrical Engineering of Southwest Jiaotong University this year. No one applied for the major of magnetic levitation at all, and the people who were admitted were basically transferred. Don't apply if you are considering employment, but if you are interested in this aspect, it is another matter. I can't find a job anyway. In the third year, I heard what they said and told me never to change this major.
