It is a masterpiece of fortune-telling theory in the Southern Song Dynasty. Its characteristics are: "gathering the theories of dozens of schools, analyzing each chapter and sentence, testing the pros and cons, and evaluating the depth." Wherever heaven, earth, and people are tangible, they are numbered, and the numbers are limited to the five elements. Therefore, those who are good at divination can predict and predict, and there are people who live among them, and there are obvious things that can be deduced. It is said that life and death have destiny, and wealth and honor are in heaven. Is this just the conjecture of a magician? Covering the five elements, there is constantness and change. It is often easy to deduce, and it is a trace; it is difficult to deduce, and it is a reason. If you don't have a clear understanding of your heart and mind, you won't be able to accomplish this. In ancient times, the person who was said to be good at what he did was none other than Li Xuzhong. Scholars will pass on their methods, and if they understand the principles from the book, they will be like Yao Ji's shot, which will hit a hundred hits.
