Lù Wénguī 陸文圭 (1252–1336; catalog meta gives 1340 as death year, CBDB 1336), zì Zǐfāng 子方, hào Qiángdōng 牆東 (“Eastern Wall”), native of Jiāngyīn 江陰 (Chángzhōu, Jiāngsū). A child-prodigy who passed the Sòng Xiánchún 1 (1265) xiāngshì in Chūnqiū at age 13 or 14. After the Sòng’s fall in 1276 withdrew to private teaching at Jiāngyīn; in Yányòu 1 (1314, age 62), under the renewed Yuán kējǔ, passed the xiāngshì a second time; declined court summons on age and illness. Broadly learned in jīng, shǐ, astronomy, geography, lǜxiàng (acoustical-and-calendrical), medicine, and suànshù (mathematics); specially adept in geography. Lived through the entire Yuán dynasty up to its later Zhìzhèng era, dying at the age of 84 — the longest-lived of the Yuán Hàn-Confucian biéjí authors. The Yuánshǐ j. 189 (Rúxué zhuàn) biography characterizes his prose as “rónghuì jīngzhuàn, zònghéng biànhuà” (fusing the Classics and traditions, vertically-horizontally transformed). His twenty-juàn collected works survive as the Yǒnglè dàdiǎn-reconstructed Qiángdōng lèigǎo KR4d0434. CBDB person 28416. Yuánshǐ j. 189.
