Whether it is the use of multimedia, the design of writing books, the production of teaching aids, or the teaching of teachers’ language, gestures and expressions, Every detail is compact and smooth, just right. Later, he was fortunate enough to listen to the lecture by teacher Xu Weibing. He compared maths classes and teaching styles in different regions.

Of course, the formation of this regional teaching style is based on different
