Shèng Rúzǐ 盛如梓 (d. c. 1302; CBDB id 10763), self-styled Shùzhāi 庶齋, was a Yuán bǐjì writer of Qúzhōu 衢州 (Zhèjiāng). He served as Chóngmíngxiàn pànguān 崇明縣判官. His one surviving work is the Shùzhāi lǎo xué cóng tán 庶齋老學叢談 (KR3j0142) in 3 juàn (the second juàn further split into a sub-juàn, effectively 4), a bǐjì of classical-historical debate, poetic criticism, and court-and-society yì shì (omitted-affairs). He met with elder Yuán-period literati (the Sìkù editors note that he “reached the early-Yuán elders’ acquaintance — hence his record carries much elders’ lingering discussion”), giving the book primary-source value for the Yuán-period transmission of late-Sòng / Jīn literary memory.
