Choosing a department in a university is a topic that is often discussed. It can be said that there are different opinions about which department is more promising or easier to find a job. Recently, "the way out for the department of mathematics" has sparked a discussion. In response to this problem, Chen Yixin, a "legislator" of Fu Jen Catholic University, pointed out that he studied mathematics for three years and finally became a "legislator" based on his own experience, which seems to be rare in politics.

Chen Yixin wrote, what can he do for the Department of Mathematics? This theme is super emotional. Because you may not know, I studied in the Department of Mathematics of Duff University for three years.

Chen Yixin also said, look at my classmates who graduated from the Department of Mathematics. They seem to know nothing, but they seem to know everything. Many teachers are professors, and many have changed their studies to information, electronics and electrical engineering to get doctoral degrees. In fact, learning mathematical logic will become better, and the social achievements in the future will be good!

Chen Yixin also talked about his views on mathematics. I didn't know the benefits of learning mathematics at first, but later it brought great help to my life. I am studying in the UK with a master's degree in development and a doctor's degree in economics. Generally, people who study for a doctorate in economics must have at least a master's degree or a bachelor's degree in economics, but I don't, so I directly study for a doctorate in economics. In addition, this paper is also engaged in quantitative analysis, which is the most mathematical part of economics.
