Shěn Shànjiān 沈善兼 (Qīng), name given in the Hǎiwài huíliú zhōngyī shànběn gǔjí cóngshū (hxwd) catalog as the author of the Hóukē xīnfǎ 喉科心法 (KR3em036). The text’s internal colophon, however, is signed by Pān Chéng 潘誠, zì Bǎozhēn 葆真 (潘誠), dated Dàoguāng dīngwèi (1847); no internal evidence supports the Shěn attribution. The catalog metadata is followed here for cross-referencing convenience but the substantive author of the Hóukē xīnfǎ is Pān Chéng. CBDB has no entry for Shěn Shànjiān; no further biographical detail located.
