Late-Southern-Sòng / early-Yuán Daoist editor and eulogist (sòngzàn 頌贊 writer), hào Jìngmíng dàozǐ 靜明道子 — a hào identifying him as an adherent of the Jìngmíng 淨明 school (the late-Sòng / Yuán Daoist movement centred on Xǔ Xùn 許遜 and its Jìngmíng zhōngxiào dào 淨明忠孝道 derivative). Known from his editorial eulogies in Yuánshǐ wúliàng dùrén shàngpǐn miàojīng zhù 元始無量度人上品妙經註 (DZ 88), where he serves as editor and commentator alongside the primary commentator Dōnghǎi Qīngyuán zhēnrén and the secondary figure Qīnghé lǎorén. Guō’s editorial remarks are marked by frequent reference to xìngmìng 性命 (1.3a, 16a, 3.44b), to Confucian texts (1.3a, 16b), and especially to Buddhist texts (most of juan 2). He explicitly states (2.35a) that while Qīngyuán insists on inner work (nèigōng 内功) and outer practice (wàixíng 外行), he himself is primarily interested in comparing Daoist and Buddhist texts. He uses DZ 318, DZ 141, and the Jìngmíng scripture DZ 563 directly (1.28a ff. = DZ 563 1.17b ff.). No CBDB record exists. The postface of DZ 88 — containing five efficacy-tales dated between 1174 and 1204 — is presumably his work.
