Yú Wànchūn 俞萬春 (1794–1849), zì Zhònghuá 仲華, was a Qīng novelist from Shàoxīng 紹興, Zhèjiāng. CBDB (id 85057) gives his dates as Qiánlóng 59 (1794) to Dàoguāng 29 (1849), consistent with the prefaces to his novel. He was the second of seven brothers. His father served as a local official in Guǎngdōng and Húnán, and the family’s direct experience of popular uprisings inspired by Shuǐhǔ Zhuàn 水滸傳 was the spur for Yú’s lifelong project, the Dàng Kòu Zhì 蕩寇志 KR4k0092. Yú began the novel around 1826–28 and worked on it for over twenty years, producing three successive drafts; he died before seeing it to print. The novel was published posthumously in Xiánfēng 1–2 (1851–52) by his son Lóngguāng 龍光, with Qián Xiāng providing financial backing. No other works by Yú Wànchūn are recorded.
