According to public information, Jiangnan University is a double-class university, and it is basically the first batch of enrollment in China, so we usually think of Jiangnan University as a university. (Note: Since 20021,one batch and two batches of Jiangsu undergraduate courses have been merged into undergraduate courses)
The education department has not divided whether Jiangnan University is a middle school or two, and the diploma is only divided into undergraduate and junior college, but several books are just folk sayings. If a university enrolls students in the first batch in a province, it is usually considered as a university; if it enrolls students in the second batch, it is usually considered as two universities.
