After graduation, we should take doctoral research as the main development direction and decide whether to go to an enterprise or become a teacher.
1. Doctoral stage is mainly to study a certain subject in the major, and has a mature theoretical basis and research direction for this subject.
2. From the development of technology theory, doctors should complete their own research projects after graduation. If the research direction is education and teaching, it is best to be a university teacher. If you don't study education, you'd better realize its technical and economic value along the research topic.
3. Doctoral major is different from ordinary major and is the essence of major. One more step will lead the forefront of this major. So don't give up your major at will, but continue to develop along your doctoral program, and there is generally no possibility of changing careers.
