Zhōu Shìmí 周士禰 (occasionally written Zhōu Shìchēng 周士稱 in the Japanese reception, an apparent graphical confusion between 禰 and 稱) is a Qīng-period paediatrician identified by the preface to the Yīngér lùn 嬰兒論 (KR3ej009) as a Qīngrén 清人. His lifedates and native place are not securely recorded; the work survives principally through a Japanese-printed edition (寬政丁巳 = Kansei 9 = 1797) published in Nagasaki by Yoshimura Masataka 吉村正隆 (zì Shìxìng 士興) on the basis of a manuscript copy brought from China by Hirokawa-shi of Heian 平安廣川子 (a Japanese physician active in Kyoto/Heian-kyō). Internal evidence and the work’s exclusive preservation in Japan suggest a mid-Qīng (early-to-mid eighteenth century) date, before the Japanese acquisition in the 1790s. The Yīngér lùn is structured in Shānghánlùn parallel-clause syntax (xíngzhèng bìng zhì dì N 行證並治第N) rather than the more conventional Qiánshì paediatric zàngfǔ idiom — a stylistic distinctiveness that may explain the work’s appeal to kobō-ha 古方派 (Classical Formulas School) physicians in Edo-period Japan.
