Lǐ Zēngbó 李曾伯 (zì Zhǎngrú 長孺, hào Kězhāi 可齋) was a grandson of the Northern Sòng chief councillor Lǐ Bāngyàn 李邦彥 (the “Wastrel Councillor”, 浪子宰相). Originally registered in Qínhuái 覃懷 (Huáizhōu 懷州, modern Jiāozuò, Hénán), the family removed south after the fall of Kāifēng and settled in Jiāxīng 嘉興 (Zhèjiāng). His floruit is firmly fixed by the dating of his three collections (1252–1265+) and by the offices recorded in the Sòngshǐ — Director of Composition (著作郎), Pacification Commissioner of Lǐngnán, Pacification Commissioner of Sìchuān (川蜀宣撫使), and finally Academician of the Hall for the Veneration of Culture (觀文殿學士). The Sìkù tíyào credits him with “outstanding practical results” on each of his many frontier postings, calling him “a famous minister of the post-Yangtze-crossing era” (南渡以後名臣). His poetry — and especially his cí — was praised for vigour but criticized for not fitting standard tonal/genre patterns. His son Lǐ Sháo 李杓 first compiled and printed the three gǎo in Jīngzhōu 荊州; later, in Xiánchún 6 gēngwǔ 庚午 (1270), a publisher’s pocket edition appeared. His extant collection is the Kězhāi zágǎo KR4d0339.
