Seven Techniques of Yin Talismans in This Classic

"The Seven Skills of Yin Fu" is said to have been written by Gui Guzi, the originator of political strategists during the Warring States Period. It is a book about the art of war and philosophy about maneuvering, moral cultivation, and wisdom in life. The book uses concise and mysterious language to explain the seven core skills of observing the weather and personnel, controlling changes, and defeating enemies. It emphasizes conforming to the laws of nature, discerning changes in people's hearts, and skillfully using strategies to achieve goals. The text is deep and obscure, and rich in meaning. It is not only a guide for cultivating the way of life, but also one of the important sources of political maneuvering and political strategy. It has been widely praised and studied by later generations of military strategists, politicians, and strategists.
