A university is called a university because it only has the qualifications of the first batch of candidates. However, since the first batch of students can be admitted, it shows that the teaching quality and strength of the school are still relatively good. Universities in China are also divided into many levels, including a batch of undergraduates, a batch of undergraduates, a batch of specialists and a batch of specialists. A school that can become a university itself has a very high reputation. If there is any difference between the two, it is the strength and popularity of the school. Generally speaking, the reputation of key universities is higher than that of universities, and the reputation of key universities may be better than that of universities.
