Zhāng Zhìyuǎn 張致遠 (fl. mid-late 13th c.). Late-Southern-Sòng official posted to Guǎngxī. Co-author with 李璆 of the Lǐngnán wèishēng fāng 嶺南衛生方 (KR3ed031). His historical record outside this work is sparse; not in CBDB. Sòng prefectural records mention a Zhāng Zhìyuǎn as official at the Guǎngxī xuānfǔshǐsī 廣西宣撫使司 in the late Sòng, consistent with the Lǐngnán wèishēng fāng attribution.
