Yú Tíngchūn 兪庭椿 (also written 俞庭椿; Southern Sòng, fl. 1172), zì Shòuwēng 壽翁. Native of Línchuān 臨川 (modern Línchuān, Jiāngxī). Jìnshì of the Qiándào 乾道 8 (1172) class, served as magistrate of Gǔtián 古田 (in Fújiàn).
Author of KR1d0006 Zhōulǐ fùgǔ biān 周禮復古編 — the founding text of the so-called “Dōngguān not lost” school (冬官不亡之派) of Zhōulǐ exegesis. Yú argued that each of the five surviving ministries of the Zhōulǐ originally contained exactly sixty office-titles; any office-title in excess of sixty must in fact have belonged to the lost Dōngguān and could be redistributed accordingly. He also argued that the Tiānguān shìfù 世婦 and the Chūnguān shìfù, and the Xiàguān huánrén 環人 and the Qiūguān huánrén, were each a single office mistakenly duplicated. Both arguments were rejected by the Sìkù editors as “fabricated and arbitrary,” but his framework was inherited and elaborated by Qiū Kuí 邱葵 and Wú Chéng 吳澄, becoming a major sub-tradition of Zhōulǐ scholarship that persisted to the late Míng.
CBDB id 43589, fl. 1172. Sòngshǐ j. 202 lists his work in three juan; the received text in one juan is appended to Chén Yǒurén’s 陳友仁 recension of Zhōulǐ jíshuō KR1d0013.
