Boyi should refer to the first year of doctoral study, not academic qualifications. Just like the first year of undergraduate course is referred to as freshman, there is senior one in high school and junior one in junior high school, and the first year of doctor is referred to as Boyi. Academic qualifications refer to people's learning experience of receiving scientific and cultural education and skills training in educational institutions. According to the education law and other laws and regulations and the relevant provisions of the state, academic education includes the following forms: primary school, junior high school, senior high school, junior college education, undergraduate education, graduate education and so on.
