吳中佩蘅子 Wúzhōng Pèihéngzǐ — “The Heng-herb-wearing One of the Wu Region [Suzhou]” — is the pseudonymous author of KR4k0244 Wú Jiāng Xuě 吳江雪 (Snow on the Wu River), a 24-chapter cáizǐ jiārén 才子佳人 romance novel. The pen name identifies the author as a member of the Suzhou (Wúzhōng 吳中) literary circle. Beyond this toponymic clue, no biographical information is available. The shorter form Pèihéngzǐ 佩蘅子 appears in some secondary references. No CBDB entry has been identified. The novel’s internal evidence and linguistic style point to an early Qing, probably Kangxi-era (c. 1662–1722), authorship, though the late Ming dating advocated by Zhèng Zhènduo 鄭振鐸 has not been entirely ruled out by subsequent scholarship.
