This book is a significant text on Chinese medicine tongue inspection, detailing nine categories of tongue diagnoses, totaling 149 entries. Each category begins with a general discussion outlining the diagnostic principles, followed by individual entries with illustrated tongue diagrams. These diagrams meticulously document the specific shapes, colors, and diagnostic significance of each tongue, along with treatment principles and medicinal approaches. As noted in the preface, "For minor ailments, diagnosis should consider both the tongue and pulse. However, for chronic or more severe conditions, when the pulse may not be reliable, one should rely on the tongue and not be constrained by pulse manifestations." This underscores the critical importance of tongue inspection in clinical practice.
