Passing by, in fact, this is related to the difference between domestic understanding and foreign understanding. Because Yi 'an Polytechnic is a polytechnic, I checked official website and school profile claimed to be the institute. Guang Mei, for example, was originally a college, but later it was upgraded to an undergraduate course for professional reasons. Another example is the Massachusetts Institute of Technology. Here I refer to a college, and a college refers to a school (science, engineering, technology, technology, or college). According to the academic environment of each school, translation into Chinese is different. MIT should be translated into Chinese as "MIT" according to the size of its departments and academic environment, but most people in China are used to calling it MIT. There are California Institute of Technology, Imperial College London, London, which was dissolved from University of London, and Swiss Federal Institute of Technology. These schools are all universities in level, but they are still called research institutes or colleges, that is, colleges. It is a junior college, but the diploma is much more valuable than many undergraduate courses. However, contrary to domestic understanding, foreigners think that universities are divided into junior colleges and undergraduate courses. A junior college specializes in the application of existing technologies, while an undergraduate course should focus more on research and development. Then you will find that many so-called universities in China have not developed this thing, and because there are too many universities in China, China people think that a college is not equal to a university. In fact, whether it is MIT or these schools I mentioned above, it is no suspense to explode domestic undergraduate courses. These colleges are in the top 50 in the international university rankings ~ ~ and to be honest ... are some so-called universities in China really universities? Hehe, it may not even be a college, but the real definition of polytechnic in English is (a name that applies to schools, colleges and universities specializing in science and technology, and educational institutions established to complete compulsory education and implement higher education equivalent to university level). In fact, I think it is really necessary to clarify the definitions and differences of academies, colleges, research institutes, polytechnics and universities in China. Many dictionaries are just general literal translations.
