Dōngxuān jūshì 東軒居士 (“Master of the Eastern Pavilion”), pseudonymous Southern-Sòng (pre-Xiào-zōng or contemporary, fl. before / during 1170, 南宋) author of the Wèijì bǎoshū 衛濟寶書 (KR3e0035) — a specialist surgical-medical treatise on furuncular abscesses (癰疽) in 2 juan, with 22 piān of disease-discussion and illustrations. The pseudonym is the only authorial signature; the SKQS editors note that no further identification is possible. The work was preserved in the Yǒnglè dàdiǎn (where the SKQS editors recovered it) and through the household manuscript tradition of the Wāng 汪 family of Méigēn 梅根, from which a Dǒng Lián 董璉 son-in-law obtained it; Dǒng’s preface (preserved in the Yǒnglè recovery) is dated to Qiándào geng-yín (1170) under Sòng Xiàozōng. So the Dōngxuān jūshì must antedate 1170 and is a Southern-Sòng (pre-1170) figure.
