Late-Míng scholar-official and polymath, zì Jìngjūn 敬君, of Xīān 西安 in Qúzhōu 衢州 (modern Quzhou, Zhejiang). Granted jìnshì in Wànlì xīnchǒu (1601). His career: from bùláng (Ministry of Personnel functionary), sent out as Prefect of Kāifēngfǔ; promoted Hénán tíxué qiānshì; reassigned Jīngxīdào cānyì; soon transferred to NánRuì, but died before he could take up the post. Author of more than forty works on diverse subjects. His one surviving work in the Sìkù is the Zìluán KR1j0047 in 2 juàn — a late-Míng descendant of the Pèiguī KR1j0027 tradition of confusable-graph differentiation, distinctive for the four-syllable mnemonic verses appended to each entry. CBDB carries an entry (#363487) without firm dates; precise lifedates not recoverable from the catalog meta.
