Early-Yuán Daoist master of Wújùn 吳郡 (Suzhou 蘇州, Zhèjiāng 浙江), styled Léisuǒ 雷所 and hào Guǐfù dàorén 癸復道人. His active years span the immediate post-Sòng period (the Southern Sòng having fallen in 1279); CBDB (c_personid 107198) records fl. 1279, consistent with the catalog-meta window fl. 1280–1294 given for his editorial activity. He re-engraved and prefaced the Sòng Daoist-scholar Lǐ Jiāmóu’s 李嘉謀 (jìnshì 1166) commentary Yuánshǐ shuō xiāntiān dàodé jīng zhùjiě 元始說先天道德經註解 (DZ 3), supplying a substantive critical preface (c. 1280–1294) that corrects the interpretation of the prior preface-writers Xiè Túnán 謝圖南 and Lǐ Zēngbó 李曾伯 (who had wrongly identified the parent scripture’s five piān 篇 with the Língbǎo / Shénxiāo Fūluò wǔpiān 敷落五篇 talismans). In the wider Daoist editorial tradition he is often associated with the compilation or redaction of Suzhou-area ritual texts of the late thirteenth century. A different individual also named 張善淵 (CBDB c_personid 107199, 1206–1275) is a generation earlier and cannot be identified with the editor of DZ 3.
