Since the 1950s, China's middle school mathematics syllabus has been revised many times, but all of them have the same guiding ideology, that is, to do well the three basics. It is emphasized that a correct understanding of mathematical concepts is the premise of mastering the basic knowledge of mathematics. At present, the outstanding problem in China's mathematics teaching is to ignore the correct understanding of the mathematical foundation, that is, the mathematical concept.

On the one hand, textbooks underestimate students' understanding ability, and in order to "reduce the burden", they dilute or even avoid some difficult basic concepts. On the other hand, the exam-oriented strategy of "sea tactics" makes teachers have insufficient time and energy to study how to make students deeply understand basic mathematical concepts. It is said that the burden is reduced, but in fact the pressure on teachers and students has increased.
