雲間嗤嗤道人 Yúnjiān Chīchī Dàorén — “The Chuckling Daoist of Yúnjiān [Songjiang]” — is the pseudonymous author of KR4k0246 Wǔ Fèng Yín 五鳳吟 (Song of the Five Phoenixes), a 20-chapter cáizǐ jiārén 才子佳人 romance novel. The toponym Yúnjiān 雲間 (literally “amid the clouds”) is the classic literary sobriquet for Sōngjiāng 松江 prefecture (present-day Shanghai area), giving the author a Songjiang cultural affiliation. The pen name also appears in variant form as 雲陽嗤嗤道人 Yúnyáng Chīchī Dàorén in some later editions and bibliographic sources; the Kanripo source file uses 雲間嗤嗤道人. Whether these two pen names refer to the same person or to two different authors is uncertain; the Kanripo corpus also preserves KR4k0158 under a person note for 雲陽嗤嗤道人, which may represent a distinct author. The Chīchī 嗤嗤 (“snickering,” “chuckling”) element is characteristic of Qing popular fiction pseudonyms signaling satirical intent. No biographical information beyond the pen name is available. No CBDB entry identified.
Note on disambiguation: The related pen name 雲陽嗤嗤道人 (Yúnyáng, not Yúnjiān) appears in the Cǎoxiántáng 草閑堂 block-print edition of Wǔ Fèng Yín and is used in several modern reprints. Given the different toponym element (陽 vs. 間), these may be two distinct pen names adopted by the same author for different editions, or they may represent two different authors; the question cannot be resolved from available evidence.
