This book is divided into Version A and Version B, with essentially the same content. Version A is transcribed after the Zubi Shiyimai Jiujing, comprising 37 lines; Version B has more missing text compared to Version A, but its beginning and end are relatively complete, totaling 18 lines. Apart from the separate records of the names of the eleven meridians, the book lacks chapter titles. There are slight differences in the sequence of describing the meridians between the two versions. The format of the Yinyang Shiyimai Jiujing is very similar to that of the Zubi Shiyimai Jiujing. For each meridian, it records the name, the course of circulation, the main diseases and symptoms, and moxibustion. Its discussion is more detailed than that of the Zubi Shiyimai Jiujing. Among the eleven meridians in this book, nine run from the extremities of the limbs towards the torso, i.e., centripetal; two run from the head to the hand or from the lower abdomen to the foot, i.e., the shoulder meridian (hand taiyang small intestine) runs from the head to the hand, and the foot taiyin runs from the lower abdomen to the ankle, which are centrifugal. The book mainly focuses on meridian diseases and distinguishes between "diseases of movement" and "diseases of production," which is very similar to the Lingshu?meridian, with some identical texts. This indicates that it is closer to the Lingshu?meridian and is included in the Wushi'er Bingfang published by the Cultural Relics Publishing House in 1979.
