According to the "Instructions for Candidates of National Medical and Health Professional and Technical Qualification Examination" issued by China Medical Qualification Examination Admissions Examination Management Center, doctors who have obtained the certificate of advanced study can engage in clinical, teaching and scientific research work for advanced study in the departments set up by their medical institutions, but they are not allowed to set up jobs. In addition, all medical practitioners must pass the national medical qualification examination and obtain the medical qualification certificate before they can legally engage in relevant clinical practice. If you want to engage in related clinical practice, you need to take and pass the national doctor qualification examination, and at the same time, you need to improve the relevant procedures such as title selection and doctor's practice certificate before you can engage in related practice.
