Can graduate students be teachers in high schools or universities?

Full-time graduate students can choose the olympiad of high school and university teachers! But you need to pass the college entrance examination or the provincial unified examination! In second-and third-tier cities, the competition among college teachers is fierce, and most of them need to start with counselors and teaching and research assistants. Being a lecturer still needs strong enough strength to have a chance!

But if you want to be a high school teacher or a university teacher, it's hard not to go to graduate school!
