Zhào Fǎng 趙汸 (1319–1369), zì Zǐcháng 子常, was a late-Yuán / early-Míng Confucian scholar from Xiūníng 休寧 (Huīzhōu 徽州, modern Ānhuī 安徽). He studied under Huáng Zé 黃澤, receiving from him the lines of Yìjīng symbol-and-line analysis and Chūnqiū 春秋 exegesis. He withdrew into private scholarship and built a residence called the East Mountain Studio (Dōngshān jīngshè 東山精舍) for the support of his mother. At the founding of the Míng (Hóngwǔ 2 = 1369) he was summoned to assist with the compilation of the Yuán shǐ 元史 but did not wish to take office; he asked permission to return home and died not long after — at the age of fifty.
The catalog meta gives his lifedates as 1319–1469, but this is a typographical error: CBDB and the standard biographical sources unanimously give 1319–1369, which is consistent with his summons to the Yuán shǐ project in Hóngwǔ 2 (1369). The corrected dates are followed here.
His main scholarly investment was in the Chūnqiū, on which he wrote the Chūnqiū jí zhuàn 春秋集傳, Chūnqiū shì lì 春秋師說, Chūnqiū jīn shū 春秋金鑰, and others; the Sìkù notice on his Zhōuyì wénquán 周易文詮 (KR1a0090) explicitly states that his Yì-writing did not approach the depth of his Chūnqiū corpus, but is nonetheless a competent supplement to the ChéngZhū tradition.
