Tóng Yuèxuān 童月軒 (fl. late 19th–early 20th c.) was a literatus-collector of Húnán Xiāngxī 湘西, scion of a hereditary household, who assembled over decades a manuscript collection of more than 200 “tested” family formulas from kin and acquaintances. This manuscript collection was published in 1923 by his friend Cài Lùqiū 蔡鹿秋 as the Lìyàn zàishòu biān 歷驗再壽編 (KR3ed065), distributed through provincial and county-level charitable halls and benevolent societies. Tóng’s collecting activity falls late-Qīng but the work as printed is Republican-era; the catalog meta assigns a Qīng dynasty marker on the basis of the underlying material. No CBDB entry.
