Yú Wénbào 俞文豹 (fl. 1240–1250; CBDB id 43551), a late-Southern-Sòng bǐjì writer. Career details unknown. He composed the Chuī jiàn lù 吹劍錄 (“Records of Sword-Polishing-Through-Whistling”) — apparently in three sequential parts — of which only the Chuī jiàn lù wài jí 吹劍錄外集 in 1 juàn (KR3j0129) survives in the Sìkù; the Sìkù editors note that his preface to the wài jí dated Chúnyòu gēngxū (1250) says he “continued from three to four [editions],” meaning two intervening volumes existed and are now lost. The Chuī jiàn lù itself has uneven argument and is faulted by the Sìkù editors as piān bó (lopsided and incoherent); the wài jí is his late-life closing-brush work and is much more sober, including a substantial historiographic essay on the dàoxué dǎngjìn (the proscription of Lǐxué) and an evenhanded assessment of Yīchuān Chéng Yí and Huìān Zhū Xī.
