Chéng Bì, zì Huáigǔ 懷古, was a Southern Sòng official from Xiūníng 休寧 (in modern Huīzhōu, Ānhuī). His clan claimed descent from a Northern Sòng line that had migrated south from Míngzhōu 洺州 in Héběi, on which account he styled himself “Survivor of Míngshuǐ” (Míngshuǐ yímín 洺水遺民). He took the jìnshì in 1190 (Shàoxī 1) under chief examiner Zhào Rǔyú 趙汝愚, and rose through provincial and court appointments to Minister of Rites and Hànlín Academician of the Duānmíng Hall (Duānmíngdiàn xuéshì 端明殿學士). The Míng-period Hóngjiǎn lù by Shào Jīngbāng accused him of having joined Shǐ Mǐyuǎn 史彌遠 in forging the edict that enthroned Lǐzōng in 1224, but the Sìkù editors of his collected works observe that surviving memorials in KR4d0302 criticise Shǐ’s policies and conclude that the slander is unfounded. He was honoured with the posthumous title Junior Preceptor (shǎoshī 少師). His writings survive as the Míngshuǐ jí KR4d0302, originally in sixty juàn but transmitted only in a thirty-juàn reduction edited in 1629 by his descendant Chéng Zhìyuǎn 程至遠. CBDB id 10755 gives lifedates 1164–1242.
