This difference can be understood as: medical practitioners have the right to carry out medical examination, disease investigation, medical treatment and issue corresponding medical certificates within the registered scope of practice, which is what we call prescription right. Assistant practicing physician is a necessary condition for medical students in technical secondary schools and junior colleges to obtain the qualification certificate of practicing physician. That is to say, secondary school or college education can not directly test medical practitioners, and you need to pass the examination of assistant medical practitioners to apply for medical practitioners.
