Tiānxiūzǐ 天休子 (“Heaven’s-favor Master”; alternate sobriquet 乾一先生 Qiányī xiānshēng, “Master Qián One”), a Dào-guāng-era (1820s–1840s) yǎngshēng author of unrecovered true name. The sole transmitted attribution is to the Xiū Kūnlún zhèngyàn 修崑崙證驗 (KR3eo003), self-dated in 1846 and prefaced in 1847 by Hóu Tóng 侯桐 of Wúxī. The internal evidence places the author in a Jiāngnán literate milieu (Hóu Tóng’s circle), but no further biographical data are recoverable. No CBDB record.
