How did the titles of bachelor, master and doctor come from?

No, modern degree titles are borrowed from ancient positions and cannot be taken literally.

The first record of bachelor's degree in "Zhou Li Chun Guan" refers to those who first studied in school. After the Wei and Jin Dynasties, a bachelor refers to an official who has written skills and worships the DPRK. According to folk custom, a well-read and literary person is called a "bachelor", the most famous of which is Su Shixue by Su Dongpo. In addition, there is a big gap between bachelor's degree and university. Most bachelors are officials with little real power, but the status of university students is extraordinary. In the Tang and Song Dynasties, all those who added "big" before "bachelor" were ministers of Zaifu. In the Qing Dynasty, college students became the highest positions of civil servants, and officials were the best.

As a kind of degree title, bachelor's degree is divided into bachelor of science and bachelor of engineering. Awarded by an institution of higher learning authorized by the State Council. A bachelor's degree shall be awarded to those who have graduated from an institution of higher learning with excellent results and reached the required academic level.

The title of master originated in the Five Dynasties, and it also refers to a person with noble moral character and profound knowledge, but it was never an official position. The ancients said that a master is great. In ancient times, those who were learned were often called "masters of old age" and "masters of Confucianism", meaning similar to masters.

In ancient China, the title of doctor had several meanings. As an official name, it first appeared in the Warring States Period. From Qin dynasty to Han dynasty, the doctor's duty was mainly to manage books and be a consultant. There were 70 doctors during Qin Shihuang's reign. Doctors in the Han dynasty were too often officials, with a rank of 600 stones and as many positions as 10. Emperor Wu of the Han Dynasty adopted the suggestion of the palace and established a doctor of the Five Classics to teach classics. In the Tang Dynasty, doctors such as Guo Zi, imperial academy and Simen were established. Another doctor of law, a doctor of writing, a doctor of arithmetic, a doctor of politics and law, is a professor at the county level, not the official name of Confucian scholars in the central religion. For example, after the Wei and Jin Dynasties, Dr. Tai Chang, who was good at etiquette, had been in charge of court etiquette. Appoint Dr. Taylor, who is familiar with temperament, to be in charge of court sacrifices and enjoy banquets, songs and dances; Appoint people who are proficient in medical skills as doctors in surgery and internal medicine; Appoint people who are proficient in astronomy, ephemeris and divination as Dr. Astronomy, Dr. Missing Engraving, Dr. Calendar, Dr. Taibu, Dr. Bo, etc. Specializing in astronomy, calendar, divination, etc.
