Dài Dé 戴德 (fl. late 1st c. BCE), zì Yánjūn 延君, traditionally distinguished as DàDài 大戴 (“Greater Dài”) from his nephew XiǎoDài 小戴 (Dài Shèng 戴聖). Native of Liáng 梁 (modern Shāngqiū, Hénán). Tutor to the Hàn Xìndū prince (Xìndūwáng tàifù 信都王太傅). The senior figure of the early-Western-Hàn ritual-school transmission going back through Mèng Qīng 孟卿 to Hòu Cāng 后蒼 to Gāotáng Shēng 高堂生 of Lǔ — the principal early-Hàn line of the Yílǐ learning. Dài Dé compiled what is now the DàDài Lǐjì 大戴禮記 KR1d0076, originally in 85 piān selected from a Western Hàn 131-piān ritual-records corpus (per the Hàn shū yìwén zhì and Zhèng Xuán’s Liùyì lùn); the parallel selection by his nephew Dài Shèng (the XiǎoDài Lǐjì, 49 piān) became canonical as the Lǐjì KR1d0052 of the Five Classics.
