Zhū Qiánzhāi 朱潛齋, early-Republican county magistrate (xiànzhǎng 縣長) of Yúshān 榆山 in Hénán. Named in the 1914 postface to KR3eq093 Chǔnzǐ yī as the official who recommended that Lóng Huìtáng’s manuscript be prepared for publication. No standard biographical record located. Not confidently disambiguated from other Qiánzhāi-styled persons (which include the more famous late-Qīng Wēnbìng physician Wáng Mèngyīng, hào Qiánzhāi 潛齋; this Zhū is a separate, early-Republican figure).
