1, Zhang Yu: Be humorous. Teaching is like telling a story. It sounds effortless. If you are not interested in mathematics, the teacher's class will stimulate your enthusiasm for mathematics, attach importance to the understanding of concepts, visualize abstract problems and simplify complex problems. Students with less training and good foundation are suitable to find teacher Zhang Yu, so as to understand the concept of high numbers more deeply.

2. Li Yongle: Jianghu people call him the king of the next generation, and Li Yongle can be said to be the leader in the postgraduate entrance examination field. One of his lectures on Li Yongle's linear algebra is a magic book for postgraduate entrance examination. The questions and methods are extremely refined, which is very suitable for the pace of postgraduate entrance examination. I suggest you not to spend too much time on online substitute books in the early stage. With a little foundation, we should immediately watch Li Yongle's enhanced video of line generation, watch it twice, take notes and absorb it.

3. Tang Jiafeng: Listening to Mr. Tang's course gives people the feeling that it is full of dry goods. Teacher Tang's courses pay great attention to mastering the basics, especially the first four chapters of the first volume of advanced mathematics. Teacher Tang gives a very detailed lecture, much more detailed than other teachers. It is very pragmatic. If the foundation is weak, follow the guidance of Teacher Tang carefully, and you will lay a good foundation. However, there are also shortcomings, that is, the class pays too much attention to the amount of questions, but the conceptual theory is not in-depth, and students need to do questions to understand them deeply.
