Northern-Sòng recluse-scholar of Hénán 河南, zì Míngyì 明逸. A disciple of 陳摶 Chén Tuán, Chōng Fàng is one of the principal hinges in the transmission of the early-Sòng Yìtú 易圖 (“Yì-chart”) and xiàngshù 象數 traditions. He retired to Mount Zhōngnán 終南 (Zhōngnánshān), where he lived as a recluse, and was repeatedly invited to court by Tàizōng and Zhēnzōng; he eventually accepted office as Yòu jiànyì dàfū 右諫議大夫 under Zhēnzōng.
His doctrinal importance is as the transmitter between Chén Tuán and the next generation: through Mù Xiū 穆修 and Lǐ Zhīcái 李之才 his line reaches Shào Yōng 邵雍; through Lǐ Gài 李漑 → Xǔ Jiān 許堅 → Fàn Èchāng 范諤昌 it reaches Liú Mù 劉牧. The whole Sòng túshū lineage as canonized in Zhū Zhèn 朱震’s Hànshàng Yìzhuàn biǎo therefore descends from Chōng Fàng.
