What should I do if the professional code of teacher recruitment is different from my own professional code?

Ask the school to issue a certificate.

The professional code of teacher recruitment and your own professional code can be proved by the school. Undergraduate students look for the academic affairs office, and graduate students look for the graduate office to prove that their major in university meets the job requirements.

Professional code generally refers to the undergraduate professional directory of colleges and universities. The Catalogue of Undergraduate Majors in Colleges and Universities is a catalogue of undergraduate majors in colleges and universities formulated and revised by the Ministry of Education (formerly the State Education Commission), and it is one of the basic guiding documents of higher education.
