Zhāng Wéishù 張惟恕 (fl. early-to-mid 16th c., Míng), literatus of Shàngcài 上蔡 in Hénán. Known principally as the postface-writer (hòuxù) to Wáng Tíngxiāng’s Shèshēng yàoyì 攝生要義 (KR3eo015), in which he identifies the pseudonymous “Hébīn zhàngrén” 河濱丈人 as Wáng Tíngxiāng (then Minister of War). The afterword carries the formula hòuxué Shàngcài Zhāng Wéishù shū 上蔡後學張惟恕書 (“Disciple of the later age, Zhāng Wéishù of Shàngcài, wrote”), signalling a younger contemporary of Wáng. No CBDB record. No other works attributed.
