There are many reasons why the second university is called a college, for example, the faculty of the college is not as good as that of the university, the specialty is not as good as that of the university, and the proportion of graduate students is low. Therefore, many two schools still fail to meet the standards for evaluating universities.

Ordinary two colleges and universities (referred to as "two colleges and universities") refer to the second batch of undergraduate admissions. In the college entrance examination, the undergraduate entrance examination scores are divided into three batches according to the scores. Ordinary two universities (two) are the second batch of undergraduate entrance examinations, second only to the first batch of undergraduate courses and one (the highest ranking). Every year, the total scores of ordinary two-line and candidates are different. Ordinary two universities (hereinafter referred to as "two universities") include: two public universities and two private universities.

The Higher Education Law of People's Republic of China (PRC) stipulates that institutions of higher learning should have strong teaching and scientific research strength, high teaching and scientific research level and corresponding scale, and be able to implement undergraduate and above education. Generally speaking, the requirements of universities are higher than those of colleges. However, this does not mean that universities are necessarily superior to colleges. In some professional disciplines, the teaching and research level of some colleges may be higher than that of some universities.

Disciplines and majors in colleges and universities: colleges and universities have different requirements on the setting of major disciplines and their covered majors, the distribution of the number of students in disciplines, the number of master's degree awarding points and the total number of ordinary undergraduate majors.
