Zhāng Dàchāng 張大昌 (zì Wéijìng 為靖; 1926–1995) was a Héběi physician, grandson of 張偓南, who inherited the manuscript scroll of the Fǔxíng jué zàngfǔ yòngyào fǎyào (KR3eh001). After the original was destroyed in 1966 he reconstructed the text from memory; a separate transcript made by a disciple also survived. In 1974 he forwarded his reconstruction to the Zhōngguó Zhōngyī yánjiū yuàn 中國中醫研究院, where 馬繼興 and others vetted it.
