Late Northern Sòng court painter active in the Xuānhé 宣和 imperial painting academy; zì Chúnquán 純全, hào Qíntáng 琴堂, a man of Nányáng 南陽. According to Zhāng Huái’s Xuānhé 3 (1121) colophon to the KR3h0027 Shānshuǐ chúnquán jí, Hán went to the capital in the Shàoshèng 紹聖 era (1094–97), presented his art, was favoured by Dūwèi Wáng Jìnqīng 王晉卿, who recommended him to the Duānwáng (Huīzōng before accession); when Huīzōng came to the throne, Hán was given the rank of Hànlín shūyìjú jīhòu 翰林書藝局祇候 and rose through Zhícháng mìshū dàizhào to Zhōngxùnláng 忠訓郎. Specialised in landscape and rock-clusters. Author of KR3h0027 Shānshuǐ chúnquán jí (1121), the most systematic surviving academy-side landscape painting treatise of the late Northern Sòng. Possibly to be identified with Hán Ruòzhuō 韓若拙 of Luòyáng named in Dèng Chūn’s KR3h0030 Huàjì; the Sìkù editors flag the question as unresolved.
