Asians generally do better in mathematics than westerners, which is based on school scores, but most of the top mathematicians are westerners, because Asian (East Asian) countries have taught more things since primary school, so their grades are better than westerners. But many people may not be interested in math, so their math scores will be mediocre in the future, especially after the college entrance examination. Mathematics was taught very simply before universities in western developed countries. After college, mathematics-related majors began to be taught more and more deeply, and students were interested in learning, so most of the top mathematicians later were westerners.
