Xià Dǐng 夏鼎 (b. 1647, zì Yǔzhù 禹鑄, hào Shàochén 紹臣), Qīng-period paediatrician active during the early Kāngxī era, native of the Chǔ-Wǎn 楚皖 (Húběi-Ānhuī) border region. He inherited a two-generation family paediatric practice from his grandfather and father. His principal work Yòukē tiějìng 幼科鐵鏡 (KR3ej011), completed in 1695, is one of the most original Qīng-period paediatric treatises, distinguished by its substantial expansion of paediatric tuīná 推拿 (massage) therapy — including the famous Tuīná dàiyào fù 推拿代藥賦 (Rhapsody on Massage as Replacement for Medicine) — and its emphasis on facial visual diagnosis. He criticised the conventional sānguān zhǐwén 三關指紋 (three-pass finger-vein) diagnostic method as yījiā yìjiào 醫家異教 (heterodox teaching among physicians) and devoted a polemical section to repudiating the conventional jīngfēng 驚風 diagnostic nomenclature. The work circulated widely in the Chǔ-Wǎn region during the Kāngxī–Qiánlóng era and spread to north China in the late Qīng.
