Sòng Zōngzhēn 宋宗真 (fl. Hóngwǔ era, late 14th c.) was an early-Ming Zhèngyī 正一 Daoist priest who served at the court of the founding Míng emperor Zhū Yuánzhāng 朱元璋 (Tàizǔ 太祖). On Hóngwǔ 7.xi.23 (= 26 Dec 1374) he was commissioned by imperial edict, together with Zhào Yǔnzhōng 趙允中, Fù Tóngxū 傅同虛, Dèng Zhòngxiū 鄓仲修, and Zhōu Xuánzhēn 周玄真, to reform the Daoist zhāijiào liturgy into a single concise standardised form. The resulting work is KR5b0151 Dàmíng xuánjiào lìchéng zhāijiào yífàn 大明玄教立成齋醮儀范. The emperor’s own Yùzhì preface to that work — a forceful critique of the over-elaborate and ineffective rituals of Buddhist and Daoist clergy in the late Yuán — is the principal external context for the commission. The biographical information on Sòng beyond this commission is scant; he held the rank of Daoist court-priest and was associated with the early-Míng standardisation effort, but did not become a prominent independent author.
