Professor is a title in the higher education system. Most of them refer to senior teachers and researchers who teach in universities or community colleges, but there is a difference between professors and researchers. Professors have teaching tasks, but researchers don't. Professor is the highest level of university teachers' titles. The word "professor" in Chinese comes from the meaning of "preaching and teaching to solve doubts".

It is the title of academic officer used in ancient China, and this position was set up in universities in Han and Tang Dynasties. This word has nothing to do with English. Japanese and China people call teachers "professors" in universities. Professors' job is to teach courses in the fields they are good at, or to give students professional training, such as science and literature.

In addition, professors must deepen their professional disciplines and obtain business cooperation opportunities by publishing papers (including government scientific consultants or business inventions). ), train their own students to have enough ability to compete with them in the future.

Balancing teaching, training, submitting papers and seeking business cooperation depends on the additional factors of school, place (country) and time. For example, among the top universities in Europe and America, universities attach great importance to professors who specialize in a single field and often regard them as the focus of publicity.
