Is the open recruitment examination for teachers unified nationwide (preparation)

At present, except for the unified recruitment of teachers in Anhui and Jiangxi provinces, the examinations of educational theory and professional courses in other provinces are not unified. Under normal circumstances, cities or counties around the country organize their own examinations and examination contents. Some areas take an education theory course, some take an education theory plus basic knowledge, some take an education theory plus professional courses, some only take professional courses, and some take basic knowledge plus professional courses. At present, it is more common to test educational theory. As for professional courses and basic knowledge of public education, some areas take the exam, and some don't. It doesn't matter where the test paper is, because the theoretical knowledge of education is universal.
