1. Normal colleges: There are more girls than boys in these colleges, and there are basically only one or two boys in some majors, such as Chinese and English.

2. Art colleges: Needless to say, there are many girls, and they are all beautiful women.

3. Nursing major of medical university: This major is basically female.

4. other liberal arts majors: such as law, Chinese, foreign languages, accounting, etc. There are more girls than boys in these majors.

5. Financial institutions: there are relatively few boys and more girls.

As for the above ratio, it's hard to say. Generally speaking, the ratio of male to female in normal universities is estimated to be 37, 1:9 for some majors such as foreign languages, 3: 7 for other arts and 4: 5 for other majors.

Colleges with more boys are mainly engineering colleges. Some engineering colleges, some majors have a class without even a woman. They are all monk classes, hehe.
