Pú Shòuchéng 蒲壽宬 (lifedates uncertain; fl. through 1272 per internal evidence in his Méiyáng rénshēn shàonóng poem), hào Xīnquán 心泉, a member of the ethnic-Persian / ethnic-Arab Quánzhōu 泉州 maritime-trade lineage and elder brother of the notorious Pú Shòugēng 蒲壽庚 — the Quánzhōu Shìbó (maritime-trade commissioner) who in 1276 refused entry to the fleeing Sòng Yìwáng and Guǎngwáng and surrendered the city to the Yuán, receiving the Píngzhāng office in reward. The historical record on Pú Shòuchéng diverges sharply: the Wànxìng tǒngpǔ preserves him as a model magistrate of Méizhōu 梅州 (modern Jiāyīngzhōu 嘉應州, Guǎngdōng) from Xiánchún 7 (1271), with a popular song commemorating his frugal-and-honest administration; the BāMǐn tōngzhì preserves him as the secret architect of the family’s 1276 surrender, who pretended to retreat to the Fǎshí Shān as a Daoist chǔshì while privately ordering his brother’s submission to the Yuán. The Sìkù editors decline to adjudicate. His poetic collection survives as the Xīnquán xuéshī gǎo KR4d0415 in six juàn. The name is written variously 蒲壽宬, 蒲壽晟, 蒲壽&KR0882; in different transmissions; the Sìkù editors prefer 宬 on the strength of Yǒnglè dàdiǎn attestations. CBDB person 14501.
