Liáng Zhèng 梁正 (Táng-period, dates not preserved), Táng-period ritualist known principally as the author of an illustrated Sānlǐ compendium Sānlǐ tú 三禮圖 (KR1d0135) — one of the two principal Táng-period precursor sources for 聶崇義 Niè Chóngyì’s authoritative Sòng-period Sānlǐ tú (KR1d0017). His work is preserved only through Niè Chóngyì’s citations; no other independent transmission survives.
He has no standard biography in Jiù Táng shū or Xīn Táng shū, and his lifespan, native place, and offices are not preserved in standard sources. He is conventionally paired with the other Táng-period Sānlǐ tú author 張鎰 Zhāng Yì in Niè Chóngyì’s citation chain. No CBDB id assigned. No DILA authority record.
