This book will introduce methods of prediction that people in Western civilization have almost never heard of. These methods were invented by the best wise men of ancient China. Some used these methods to save their own lives or the lives of others, some used these methods to defeat their enemies without a single soldier, and some used these methods to establish themselves as wise men and become saints.

As for you, what do you want to do with these methods? It is up to you. But if you don't realize that many things can be predicted, or even that some things can be handled in this way, then of course you will do what you have done in the past. Then of course, you will be like countless people in the past, and live a life of mediocrity.

Many people have relied on religion and made a lot of money by lying about prophecies. Why is it that false prophecies based on religion are so easy to accept, while predictions based on one's own intelligence are not well known? Perhaps it is because in Western civilization, religion has a stronger restraining power that has constrained human development in prediction. Or maybe the answer doesn't matter. Especially once you have mastered the methods offered in this book, you probably won't care!

Of course, some of the methods mentioned in this book are only applicable to ancient contexts, but there are many more examples that will allow you to expand your thinking! Let you know that there are many ways to approach a certain situation! If you don't want to be confined to your own civilized world, and you want to try to make intelligent predictions yourself, then this book is for you. Then this book will be a treasure for you, it will open a door to a new world for your mind.
