Hán Biāo, zì Zhòngzhǐ 仲止, hào Jiànquán 澗泉, was the son of the Northern-Sòng-recovery historian Hán Yuánjí 韓元吉 (Nánjiàn 南澗, 1118–1187) — friend of Zhū Xī, Lù Yóu, Yáng Wànlǐ, and Zhāng Shì — and a member of a senior official family with roots in Yánlíng 嚴陵 (Tónglú 桐廬, Zhèjiāng) but settled by his father’s generation in the Shàngráo 上饒 region of north-eastern Jiāngxī. Hán Biāo himself never took the jìnshì and held no substantive office, choosing instead the “recluse-poet” self-styling that the hào “Jiànquán” registered. Together with the slightly older Zhào Fān 趙蕃 (Zhāngquán 章泉, 1143–1229) he formed the centre of the regional poetic circle later known as the “Two Quán” 二泉, much admired by Fāng Huí 方回 in his Yíngkuí lǜsuí. His surviving works in the Kanripo corpus are the bǐjì Jiànquán rìjì KR3j0122 and the verse collection Jiànquán jí KR4d0342, both recovered by the Sìkù editors from the Yǒnglè dàdiǎn. CBDB (id 10187) gives lifedates 1159–1224, but 1160–1224 is the more usual figure cited in biographical handbooks and in the Kanripo catalog meta.
