Sòng scholar from Chéngdū 成都, courtesy name Bóshū 伯樞. CBDB ids 13977 and 686438 attest his name and dynasty but no lifedates. The Sìkù editors note that the beginning and end of his official career cannot be verified. He is principally known as the compiler of the Liánlì zhuàn 廉吏傳 (KR2g0021) — 114 short biographies of incorruptible officials from the Spring-and-Autumn period through SuíTáng, each closing with the editor’s lùnduàn — one of the foundational Sòng instances of the moral-categorical zhuànjì·zǒnglù sub-genre. The original ten-juàn form attested in the Shūlù jiětí survives in the WYG only as a compressed two-juàn recension with the same 114 entries.
