Zhū Shūzhēn 朱淑眞 (CBDB and the Sìkù catalog meta both give c. 1095–c. 1131; many modern scholars place her later, c. 1135–c. 1180), self-styled Yōuqī jūshì 幽棲居士 (“Retired Layman of the Quiet Perch”), of Hǎiníng 海寧 in LiǎngZhè (modern Zhèjiāng). One of the two most famous women poets of the Sòng (the other being Lǐ Qīngzhào 李清照). The biographical jìlüè 紀畧 prefixed to her surviving collection claims her as a niece of Zhū Xī 朱熹 (Wéngōng 文公), but the Sìkù editors rightly note that Zhū Xī’s family was HuīzhōuMǐn, with no recorded sibling registered at Hǎiníng — the kinship claim is almost certainly a later puff. Her Duàncháng shījí 斷腸詩集 in ten juǎn (recorded by Shūlù jiětí) and the Duàncháng cí KR4j0058 in one juǎn take their title from the standard story that her “match did not accord with her ideal, and so she could not follow her true wishes; she composed the Duàncháng collection in ten juǎn to assuage herself” — i.e. a poetics of conjugal grief. The collected biography by Wáng Tángzuǒ 王唐佐 of Línān further frames her life story. The relation between her name and the corpus has been chronically unstable: Yáng Shèn’s Cípǐn attributed to her the famous Shēngzhāzǐ 生查子 line Yuèshàng liǔshāo tóu, rén yuē huánghūn hòu 月上柳梢頭，人約黄昏後 (“The moon climbs above the willow’s tip; a tryst at twilight”) — a piece that is in fact by Ōuyáng Xiū 歐陽修 (preserved in his Liúlíng jí), erroneously attributed to her in the late-Míng Cǎotáng shīyú line, and so blamed on her by Máo Jìn. The Sìkù editors expressly correct this and refuse to entertain the moral slur Yáng Shèn made of it. CBDB 39816 has 1095–1131; if the conventional later dating is correct her CBDB entry is too early by roughly a generation.
