Chéng Chōng 程充 (mid-Míng physician-editor, fl. Chénghuà era 1465–1487), Xiūníng 休寧 (Hīzhōu, Ānhuī) physician who in Chénghuà 17 (1481) produced the standard recension of 朱震亨 Zhū Dānxī’s Dānxī xīnfǎ 丹溪心法 (KR3er018) — five juǎn organised by disease-category, with Dānxī’s clinical àn 案 interleaved. The Chéng 1481 recension became the textual basis for all subsequent Míng and Qīng editions of the Dānxī xīnfǎ and is the textual basis of the present hxwd transmission. Chéng’s biographical detail is otherwise sparse; he was active in the Hīzhōu Dānxī-lineage circle that produced both Chéng’s recension and 方廣 Fāng Guǎng’s later (1536) Dānxī xīnfǎ fùyú (KR3er019). No CBDB record under this name and zì; the conventional Chinese-medicine reference dating follows the Chénghuà 17 (1481) self-imprint.
