万全

Wan Quan's birthplace, dates of birth and death, and other biographical details are limited in publicly available sources and cannot be confirmed. The five works held in the collection show that his writings focus on traditional medicine while also touching on literary appreciation. Representative titles include *You Ke Fa Hui* (Expounding Pediatrics), *Wan Family's Tradition of Expounding Pediatrics*, *Wan Family's Tradition of the Four Essentials of Nourishing Life*, and *Guang Si Ji Yao* (Compendium on Extending Progeny). These works chiefly address pediatric diagnosis and treatment, health preservation and regimen, and fertility, and reflect the compilation of family-transmitted medical knowledge—the phrase “family tradition” in the titles indicating an approach based on passing down clan experience. His writing is practical and clearly organized, making it easy to consult by illness pattern and regimen category, and his works are therefore often cited in the literature of Chinese pediatric medicine and health preservation. Given the limited sources, further research is needed on his specific medical career and scholarly background.
