Dai Sheng (traditional Chinese: 戴聖; simplified Chinese: 戴圣; pinyin: Dài Shèng), also known as Xiao Dai, (simplified Chinese: 小戴; literally: "Little Dai"), birth and death unknown, was the Scholar of Rituals to Emperor Xuan of the Former Han Dynasty. He was the son of Dai Ren (戴仁) and the younger brother of Dai De. He was a native of Liang (now Shangqiu, Henan) and a founder of the Former Han Dynasty Jinwen Jingxue (今文经学, School of Confucianism).
He helped compile the Book of Rites (礼记), whittling the 85 books of Dai De's version down to 46. To this were added three books, giving the 49 that have come down to us today.[1] Dai Sheng's version is also known as 小戴礼记.
