Five volumes. Written by Wang Shi-xiong (Meng Ying) and published in the second year of the Xianfeng era (1852). Wang came from a family of physicians and began practicing medicine in the tenth year of the Daoguang era (1830). He had profound clinical insights into warm diseases. This book takes "the texts of Xuanyuan, Qibo, and Zhang Zhongjing as the warp, and the theories of Ye (Tian Shi), Xue (Sheng Bai), and others as the weft," distinguishing between latent-qi warm disease and externally contracted warm diseases, hence the title "Jing Wei" (Warp and Weft). Volume 1 excerpts the Neijing on the etiology, symptoms, diagnosis, and treatment of warm febrile diseases; Volume 2 collects and annotates discussions on warm febrile diseases from Zhang Zhongjing's works, establishing principles for pattern identification and treatment; Volume 3 includes Ye Tian-shi's "Treatise on Externally Contracted Warm Heat" and "Treatise on Latent-Qi Warm Disease and Externally Contracted Diseases in Three Seasons"; Volume 4 compiles discussions on warm diseases, damp-heat diseases, and pestilence by Chen Ping-bo, Xue Sheng-bai, Yu Shi-yu, and others, extensively citing original works by Hua Xiu-yun, Wu Ju-tong, Zhang Xu-gu, and other renowned scholars for interpretation; Volume 5, "Formulas and Discussions," selects 113 formulas.

The entire book can be considered a comprehensive summary of warm disease theories in the Qing dynasty. However, Wang held different academic views from his predecessors on theories such as "yang pathogens cause heat, yin pathogens cause summerheat" and "summerheat must be accompanied by dampness." His annotations, combined with his personal clinical experience, are highly insightful and have, to some extent, advanced the development of warm disease theory. The existing editions include the original print, various Qing dynasty prints, and over 40 modern editions.
