Wan Wei Mathematics is a book that I have been writing recently. This book has not been published for a long time and is not very famous in Wuhan, because one of the authors is my friend. He gave me a copy, and I took it back and read it carefully.

The characteristic of this book is that it is difficult. Generally speaking, the topics in it are all difficult. Basically, it is for students who are interested in learning to master, or for children who are interested in learning to master. The difference between it and the new observation training is that although it is difficult, this set of books classifies the problems in a particularly detailed way, and each problem should be refined and concise. After reading it, I feel that this book should be of great value to students with good grades.
