Much depends on the scope of your medical practice. Being a teacher directly can't make this shell with a little influence. If your major is plastic surgery, you can do it, so as long as you can apply for a medical practitioner, you can apply for that major as long as you are approved. Another way is that you choose to see a doctor. You can change the scope of practice because of your high academic qualifications, or you can go to a hospital above the provincial level. According to the provisions of the Law on Medical Practitioners, well, you can change after a period of training.
