This book is a pediatric work, and the author is unknown. The History of Song: Biographies of Fangji and Bibliographical Treatise first recorded Shiwu Luxin Jing. It is generally believed that the book was a work attributed to Shiwu by people from the late Tang to early Song periods. It was lost after the Ming Dynasty. The currently seen Luxin Jing mostly takes the version compiled during the Qing Dynasty from the Yongle Encyclopedia as the original source. The existing versions mainly include the Siku Quanshu compilation in 2 volumes, and a photolithographic edition published by the People's Medical Publishing House in 1959.

The book is divided into two volumes. The first volume discusses pediatric pulse methods, syndromes, treatments, and special diagnostic and differential methods for children's diseases, with detailed discussions on syndromes such as convulsions, epilepsy, madness, malnutrition, dysentery, and erysipelas. The second volume contains 15 manifestations of erysipelas, with treatments mostly involving secret formulas, totaling 16 syndromes and 19 formulas. The book's Zhuyou methods preserve the content of early medical texts.
