Chén Fùzhèng 陳復正 (hào Fēixiá 飛霞 / Fēixiá dàorén 飛霞道人, fl. early-mid 18th century), Qīng-period paediatrician of Luófú mountain 羅浮山 (modern Bóluó 博羅 county, Guǎngdōng). A Daoist-monk physician of the jīndīng huǒfú xìngmìng 金鼎火符性命 (golden-cauldron-fire-talisman inner-alchemy) tradition, he turned to medical practice as a means of jìshì 濟世 (saving the world); his life-story is one of piáolì yúnyóu 瓢笠雲遊 (gourd-and-bamboo-hat wandering) through Lǐngnán. His principal work Yòuyòu jíchéng 幼幼集成 (KR3ej013) in six juǎn, completed in early 1750 (Qiánlóng 15, gēngwǔ 庚午) at the Zhǒngxìng cǎotáng 種杏草堂 of Suìyáng 澻陽, is one of the most influential Qīng paediatric treatises and the principal Qīng-period polemic against the jīngfēng 驚風 diagnostic category. He proposed substituting the term chù 搐 (convulsion) for jīng 驚 and tripartite the category into wùchù 誤搐 (mistakenly diagnosed as convulsion), lèichù 類搐 (convulsion-resembling), and fēichù 非搐 (non-convulsive). The work was prefaced by Qiú Rìxiū 裘日修 (1712–1773, jìnshì, Inner Cabinet Academician) and Liáng Yù 梁玉 (jìnshì, Lóngquán 龍泉).
