Zhāng Cìzhòng 張次仲 (1589–1676), zì Yuánhù 元岵, was a late-Míng / early-Qīng Yìjīng and Shī-classics scholar from Hǎiníng 海寧 (modern Zhèjiāng 浙江). Active across the dynastic transition, he refused to serve under the Qīng and lived as a Míng loyalist scholar in retirement; the Sìkù notice classifies him as “Guócháo” 國朝 (Qīng) by his death-date, while the catalog meta places him under 明.
His major Yì work is the Zhōuyì wàn cí kùn xué jì 周易玩辭困學記 (KR1a0114) in fifteen juàn, drafted from his early manhood in self-imposed monastery seclusion (蕭寺) and revised six or seven times over twenty-some years; the work is yìlǐ-oriented and ethically focused on practical conduct under late-Míng adversity. Zhāng explicitly refuses both xiàngshù numerology and chènwěi 讖緯 apocrypha, building his reading from the canonical wording itself with the Confucian Wings as guide. His other major works are on the Shī: Shī jīng dài yīn 詩經待印 (a Shī commentary in the Mǐnxué tradition) and Shī jīng cuò zōng 詩經錯綜.
