Sòng Xǔ 宋詡 (fl. late 15th c.), zì Jiǔfū 久夫; native of Huátíng 華亭 (Sōngjiāng prefecture, modern Shànghǎi). A gentry-family head who composed three of the five sections of the family work Zhú yǔ shān fáng zá bù 竹嶼山房雜部 (KR3j0171): Yǎngshēng bù (Nurturing Life, 6 juàn), Yànxián bù (Leisured Quiet, 2 juàn), and Shùxù bù (Trees and Livestock, 4 juàn). His son 宋公望 (Sòng Gōngwàng) added the remaining two sections; his grandson 宋懋澄 (Sòng Màochéng) compiled the whole. The Huáng Yújì Qiānqǐngtáng shūmù records a different recension that additionally includes Jiāyào, Zōngyí, and Jiāguī in the Sòng-family corpus, but the WYG copy preserves only the five sections grouped by Sòng Màochéng. No further biographical record survives.
