Xuē Yú 薛嵎 (b. 1211, alive into the early Yuán), zì Zhòngzhǐ 仲止 (a variant Zhòngyǐng 仲頴 is also attested in CBDB), alt. zì Bīnrì 賔日, hào Yúnquán 雲泉 (“Cloud-Spring”), was a late-Sòng poet of Yǒngjiā 永嘉 in Wēnzhōu 溫州 (Zhèjiāng). Native of the Tīyún 梯雲 lane in Yǒngjiā town (CBDB běnguàn 溫州永嘉縣在城梯雲坊). He passed the jìnshì examination in Bǎoyòu 4 (1256) — placed in the wǔjiǎ 五甲, position 38 (Bǎoyòu sìnián dēngkēlù 寶祐四年登科錄, 78b) — and served as Recorder (zhǔbù 主簿) of Chángxī 長溪 county in Fúzhōu 福州.
Xuē was a second-generation inheritor of the Yǒngjiā Sìlíng 永嘉四靈 (Yǒngjiā Four Spirits: Xú Zhào 徐照, Xú Jǐ 徐璣, Wēng Juàn 翁卷, Zhào Shīxiù 趙師秀) — the late-12th / early-13th-century Yǒngjiā poets who, with the moral and editorial support of their townsman Yè Shì 葉適, promoted the late-Táng plain manner of Yáo Hé 姚合 of Wǔgōng 武功 against the prevailing Jiāngxī school’s denser, allusive style. The Sìkù tíyào presents Xuē as the initial (good) phase of the Yǒngjiā lineage, distinguishing him from the late (decadent) phase that would feed into the late-Sòng Jiānghú school. The exact date of his death is not recorded; he is presumed to have survived into the early Yuán. Compiled works in the Kanripo corpus: KR4d0378 Yúnquán shī 雲泉詩 — a one-juàn selection reconstructed by the Sìkù editors from the Yǒnglè dàdiǎn.
