6. Why do I recommend all the books for the postgraduate entrance examination? Because, in the final analysis, it is still necessary to take the postgraduate entrance examination. It is better to look at other materials directly, rather than reviewing the materials for postgraduate entrance examination, so that the path will not be biased. These materials are classics, which are worth studying again and again, especially Li Yongle's Book Review, a classic among classics. Of course, I suggest you know the after-class questions first. Memorize the knowledge points in the textbook, master the source of each principle and how to push it.
