Fāng Guǎng 方廣 (zì Yuēbǐng 約竚, hào Gūshí shānrén 古石山人, fl. Jiājìng era), Míng physician of Xiūníng 休寧 (Hīzhōu, Ānhuī). His principal work, the Dānxī xīnfǎ fùyú 丹溪心法附餘 (KR3er019, dated Jiājìng 15 = 1536), is a twenty-four-juǎn expanded recension of KR3er018 Dānxī xīnfǎ incorporating extensive supplementary clinical material from Dài Sīgōng’s Zhèngzhì yàojué 證治要訣, Wáng Lún’s 王綸 Míngyī zázhù 明醫雜著, and other Míng Dān-xī-lineage works. The work circulated continuously through the Míng and Qīng and was particularly influential in Korea, where it was a standard reference in the Dōngyī bǎojiàn 東醫寶鑑 (Hŏ Chun, 1613). The Sìkù quánshū zǒngmù accepts the FāngJiājìng attribution. No CBDB record under this zì. Not to be confused with the homonymous modern Buddhist-text scholar 方廣錩 Fāng Guǎngchāng (b. 1948), Dūnhuáng manuscript specialist, who has a separate person note.
