Mèng Zhèn 孟震, Northern-Sòng official-scholar of the late Yuánfēng to Yuányòu era (ca. 1080s–1090s), preface-writer for 董汲 (Dǒng Jí)‘s Lǚshě bèiyào fāng 旅舍備要方 (KR3ed111). The preface places him as a colleague or senior acquaintance of Dǒng Jí, also literate in the medical classics and apparently in officialdom alongside Dǒng. No further biographical record is securely identifiable; the homonym 孟震 is reasonably common in Sòng-period records and disambiguation requires more contextual data than the preface gives.
