Mid- to late-Qīng physician and poet of Shuāngliú 雙流 (Chéngdū prefecture, Sìchuān). A child examination-prodigy who would have continued in the examination track but for the development of a crippling jiǎojí 腳疾 (leg-disease) in 1842; cured it himself five years later by following the Sùwèn Wěibì lùn 痿躄論 chapter (Sùwèn 44) and tonifying-and-warming protocols, an experience that turned him to medicine. His earlier-career literary work Zuìyín shīcǎo 醉吟詩草 was prefaced by his teacher Sòng Xīqiáo 宋西橋. His sole extant medical work is KR3er098 Yīxué jíchéng 醫學集成 (completed Tóngzhì 12 / 1873, printed Tóngzhì 13 / 1874), a four-juǎn clinical compendium reprinted multiple times in the late Qīng and Republican periods (including a Guāngxù 12 / 1886 Yìyuántáng edition, a 1921 Liú-family Shuāngliú reprint with bronze-man diagrams, and a Yìxīn shūjú lithographic reprint under the alternate title Yīxué zhǐnán 醫學指南). Best known by his zì Qīngchén 清臣. Birth-year c. 1804 derived from his self-preface (age 70 suì in 1873). Not in CBDB. Note: the catalog metadata for KR3er098 erroneously gives the preface-writer 駱世馨 Luò Shìxīn as author; the actual author is Liú Shìlián as identified by the self-preface.
