Jízhāi Jūshì 亟齋居士 (“The Lay-master of the Studio of Anxious Concern”), pseudonymous author of the Dáshēng biān 達生編 (KR3ei055) of 1715, one of the most widely-circulated and dōngāted popular obstetrical handbooks of the Qīng. Hinrichs & Barnes (2013), drawing on Yi-Li Wu (2010), describe the author as “a lower-level literatus who identified himself only as ‘Lay Buddhist Jizhai’.” The studio-name 亟齋 alludes to the Yìjīng hexagram gé 革 (“urgent”) and to the Buddhist preoccupation with the urgency of human life. The author’s true identity is not securely established; the work circulated explicitly under the pseudonym in conformity with the merit-accumulation (gōngdé) ethic of Buddhist charity-printing. Not in CBDB; not in any standard biographical reference.
