Postdoctoral students can easily misunderstand that "postdoctoral students are doctors or above"; The postdoctoral station is actually a mobile workstation. Eligible doctors can apply to be postdoctoral in the post-doctoral mobile station recognized by the state, and do corresponding research projects during the period. After the expiration, they can leave the station. In order to further improve the postdoctoral system in China, encourage the majority of postdoctoral researchers to work hard and achieve greater scientific research results, the thirteenth meeting of the National Postdoctoral Management Committee decided to issue postdoctoral certificates to postdoctoral researchers who have left the station and reached a certain standard (usually two years). Therefore, "postdoctoral" is actually a kind of work, and having a "doctorate" is a necessary condition for applying to become a "postdoctoral".

A postdoctoral fellow refers to a person who has recently obtained a doctorate. 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 generally called postdoctoral researchers, or simply "postdoctoral researchers".

Postdoctoral research is actually just an experience after getting a doctorate. It is neither a degree nor a professional title. He is another research job. In western developed countries, due to the special needs of professors there, it is generally impossible to find a job or experience this job immediately. Of course, he is very helpful to adapt to future research work. There is no fixed limit to this time period, and some topics take a long time. Professional titles are said in our country, but only in foreign countries. Not academic qualifications, but professional titles.

With the increasingly fierce competition in science and technology, the cultivation of talents, especially young and senior research talents, has attracted much attention from all countries, and the postdoctoral system has become an important way to cultivate top-notch talents in many countries.

The stage of further study in institutions of higher learning or research institutions after obtaining a doctorate. Also refers to postdoctoral researchers.
