Is it consistent for Huanghua Middle School to recruit teachers to ask graduate students to master this major?

No need. According to the inquiry of official website in Huanghua Middle School, the recruitment of teachers in Huanghua Middle School does not require graduate students to major in the same field. Postgraduates are different from undergraduates, and candidates with the same major as those applying for the post can apply for the exam according to the undergraduate major, but they are regarded as previous graduates, and their household registration is limited.
