Late-Southern-Sòng / early-Yuán Daoist known only from his hymns (sòng 頌) and undated preface to Yuánshǐ wúliàng dùrén shàngpǐn miàojīng zhù 元始無量度人上品妙經註 (DZ 88), styled “Elder of Qīnghé” — Qīnghé 清河 being a district created around 1270 within Huáiān prefecture 淮安府 (Jiāngsū 江蘇), near Dōnghǎi 東海, the locality of his master Dōnghǎi Qīngyuán zhēnrén. His preface announces the publication of Qīngyuán’s commentary as a “breakthrough” in Dùrénjīng understanding. No CBDB record exists. His hào also appears in the text at 1.16a and 2.17a, where his phrasing is noted for the vernacular demonstrative zhègè 這箇 — a Sòng-era colloquial diagnostic that, together with the Qīnghé toponym, anchors the text to the late thirteenth century.
