Now compare the employment situation of basic mathematics and subject mathematics. As far as I'm concerned, it's best for them to find a job, whether to go to a key high school or math education, and pay attention to the direction of math education below basic math. But it doesn't mean that subject mathematics is not easy to find. To put it bluntly, the top teachers in the country are easy to find. As long as you pass the exam, I have hardly heard of any job that is hard to find. In addition, subject mathematics is now highly recognized, and I have hardly heard of any school that does not recognize subject mathematics.
