The professional classification applicable to civil servant recruitment is not uniform. Some provinces tentatively give some professional classification catalogues of civil servant examinations in their own provinces. Some provinces refer to the standards of the Ministry of Education for their explanations, and some do not mention majors directly.
However, you can also refer to the professional catalogue published by the Ministry of Education and the undergraduate professional catalogue of ordinary colleges and universities (20 12) 202 1 national civil service examination professional classification 202 1 national civil service examination majors are divided into philosophy, economics, law, education, literature, history, science, engineering, agriculture, medicine, management and art.
There are professional restrictions when applying for different positions. Just look at the job list and you can get a general idea of the scope of your application. Every year, before the civil service exam, a job list will be released, which can be found online.
I believe that the civil service examination can be defeated by choosing a suitable post and through your own efforts! I hope my answer will help.
