China has indeed made great progress and promotion in technical mathematics. All our students are better at basic computing than American students. Although it is not as exaggerated as uploaded online, it is definitely better than their overall level. But we are only in the field of elementary mathematics, and our understanding of advanced mathematics, such as calculus, is much worse. Now many of our college students don't know what calculus is. After four years in college, they didn't know calculus, but they studied mathematics for three years.
A big mathematical country does not mean a strong mathematical country. We need to do more research in the field of advanced mathematics, which is limited by history. This is true, because advanced mathematics originated in the west, and Newton was the founder of calculus. He can be said to be the founder of the earliest classic limit. Although he later optimized the concept of the basic limit of calculus, the optimization was still in the west because we had nothing to do with it. When Newton studied the motion state of objects, he found that the existing mathematical system could not satisfy him.
Even if you are not a math major in college, some subjects of economic management will study advanced mathematics. Although it is not as deep as mathematics major, the basic calculus deformation is involved in finding the original function, definite integral and indefinite integral, but many students don't know what calculus is after graduation, and you don't know how to calculate indefinite integral. This is the limitation of our mathematics, because we regard advanced mathematics as particularly difficult, and we regard it as mathematics. We need to put more energy into the research of advanced mathematics, because elementary mathematics can now be replaced by computers to a certain extent, and we must do something that computers can't replace if we want to make progress.
