SòngYuán 宋-元 Daoist scholar, author of the [[KR5c0148|Tài shàng xuán líng Běi dǒu běn mìng yán shēng jīng zhù]] (DZ 752) — one of three Daozang commentaries on the Dipper longevity-scripture.
Name. “Fù Dòng zhēn” 傅洞真 — the combination of surname (傅 Fù) with the Daoist-register given name Dòng zhēn 洞真 (“Cavern-Perfection”, a classical Daoist technical term for the highest scriptural category) suggests a Daoist hào rather than a secular personal name.
Activity. The commentary is undated but preceded DZ 750 (1334, Xú Dàolíng) which cites DZ 752’s talismans. Therefore active before 1334, most plausibly in the Southern Sòng (1127–1279) or early Yuán period (1280s–1320s). No precise lifedates.
Contribution. DZ 752 preserves the authoritative canonical set of talismans for the Dipper-deity cult — widely cited in subsequent Daoist iconographic and liturgical literature.
