After graduating from college, I got a postgraduate degree. Education in China is mainly divided into three stages: primary education, secondary education and higher education. Primary education is primary school, secondary education includes junior high school, technical secondary school, vocational school and technical secondary school, and higher education includes junior college (higher vocational and high-tech), undergraduate, master and doctor. The degree after undergraduate course is a postgraduate degree, and the degree after junior college should be a bachelor's degree. At present, the graduate degree is the highest. Undergraduate graduates and previous graduates can directly apply for postgraduate education, and junior college students can apply for postgraduate education only after obtaining two years or more of college education.
