Mathematics courses taught in normal universities are shallow, but they are also very practical. After all, mathematics is a subject at all stages of learning. If you are a teacher, you will have a wide range of employment. Even if you don't be a teacher, you will earn a lot by expanding your sideline to help coach junior high school mathematics/advanced mathematics/postgraduate mathematics.

In addition, different colleges and universities will add various practical courses on the basis of pure mathematics, such as algorithms (high-paying employment) and computers (equally high-paying employment), which can easily be transferred to the financial investment industry.

If you don't get a direct job and go to graduate school, you will have advantages in both studying and changing your major. Science and engineering teachers like students who are good at math, and anything related to calculation will be faster. Not to mention reading a PhD or above, even as a university teacher, advanced mathematics is something that almost every major will learn.

The picture shows the direction that some mathematics majors can take in the postgraduate entrance examination. It can be seen that the choice is very wide (to some extent, it also implies a wide range of employment).
