title: [Analysis on the finalized date and first carving time of Wei sheng bao jian (The Precious Mirror of Hygiene)].
abstract: The Wei sheng bao jian (The Precious Mirror of Hygiene), written by Luo Tianyi should be finished in the spring of 1283. The wrong date of 1281 was a mistake coming from Yanjian's Preface, while the complete date of 1343 was a misunderstanding on "Guiwei year of the Zhiyuan reign" in Wangyun's Preface. The hypothesis that Wei sheng bao jian was first carved in 1294 or before the Tang ye ben cao (Materia Medica for Decoctions) is also groundless. The book was probably completed, carved and distributed in the same year, or no later than 1307, even if it was not carved in the same year right after its completion.
