Wang Kunlun is a famous person in the field of special mathematics education and training in China. He initiated the great mathematics era of Khan Academy in China, and was invited as a special lecturer of Wang Fang's "first training camp". Since I was a student, I have been devoted to studying the methods of learning mathematics and constantly exploring in the first-line mathematics teaching.
