"Looking for the Source of Da Liuren" is a classic work by the ancient scholar Zhang Chunzhao who systematically combed the art of Liuren. As one of the three ancient Chinese prediction systems, this book is based on the astronomical calendar, integrates the principles of yin and yang, the five elements, and the principles of the stems and branches to construct a sophisticated space-time deduction model. The "Five Essentials and Balances" system in the book summarizes the Liuren Judgment Law into core principles such as self, inside and outside, subject and object, superiority and inferiority, and time of day. It includes not only the division of subject and object of "the day is for me, the three transmissions are for things", but also the dynamic decision-making logic of "it is better to advance when passing on, and it is better to retreat when passing on".
The book is supported by a large number of empirical examples, such as inferring theft of property through hazard-related classes and analyzing personnel changes through cut-off classes, transforming abstract theories into actionable practical guidelines. Zhang Chunzhao particularly emphasized the dialectical thinking of "seeking for the strange but not for the strange", advocating that the five elements should be restrained and avoid over-reliance on the method of change, reflecting a rigorous academic attitude. Whether it is corporate strategic decision-making, personal development planning, or interpersonal relationships, readers can gain wisdom and enlightenment across time and space. As a bridge for Liuren Shu to move from palace secrets to mass application, this book can be called a classic interpretation of the idea of "harmony between man and nature" in traditional culture.
