Postdoctoral degree is the highest. Postdoctoral students refer to some people who have recently obtained doctoral degrees. Before becoming full-time researchers, they obtained subsidies from relevant departments through competition and engaged in research work in high-level research institutions to gain scientific research experience.
These people are postdoctoral researchers, referred to as "postdoctoral". Postdoctoral research is actually just an experience after getting a doctorate. It is neither a degree nor a professional title.
Postgraduate education includes master's degree and doctor's degree. In other words, only a master's degree or a doctor's degree can be considered a master's degree or a doctor's degree. A master is a doctor, so the level of a doctor is one level higher than that of a master, and only a master can study for a doctor.
Extended data
The names of bachelor, master and doctor have existed in China since ancient times. But it doesn't mean that China had a degree system in ancient times. Doctor, an ancient official title, is engaged in compiling works or teaching students and cultivating talents.
Doctor ranking is not tasteful. Bachelor, at first, only refers to the disciples who are studying. After Wei and Jin Dynasties, he became a literate official who worshipped the imperial court, and his taste was not high.
Emperor Taizong set up a literary museum, and the status of a bachelor was greatly improved. From the Song Dynasty to the Qing Dynasty, bachelors always had high taste. In Qing dynasty, the rank of college students was the first among civil servants.
