As we all know, bachelor's degree, master's degree and doctor's degree are the degrees of higher education in China. Modern universities and the degree system have only been in China for a few years, but the names of these degrees have existed since ancient times, but they were not used to be awarded to college students and graduate students, and they were not arranged in the order of bachelor, master and doctor.

The term "bachelor's degree" first appeared in the record of Zhou Li Chun Guan, which first refers to those who studied in schools. After Wei and Jin Dynasties, bachelor's degree refers to officials who were enshrined in writing skills. According to folk custom, a well-read man with literary talent is called a "bachelor", and the most famous one is Su Dongpo's "Su Xueshi". In addition, there is a big gap between the bachelor and the university. Most of the bachelors are officials with little real power, but the status of the university is extraordinary. In the Tang and Song Dynasties, all the people who added "big" before "bachelor" were Zaifu's ministers. In the Qing Dynasty, university students became civil servants, and in the Qing Dynasty, university students became the highest position of civil servants, and officials were the best, which was a real high position.

the title of master originated in the five dynasties, and it also refers to people with noble character and profound knowledge, but one is not an official position.

The doctor originated in the Warring States period, and is an official position, responsible for keeping documents and files, compiling works, imparting knowledge and cultivating talents. During the reign of Emperor Wu of the Han Dynasty, the doctor became a scholar specializing in teaching Confucian classics. Book of Changes, Book of Songs, Poems, Rites, and Spring and Autumn Annals each have a doctor, who teaches them in the way of family, and the doctor of the Five Classics of Happy Birthday.
