Late-Míng scholar-official and polymath, 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 Nán-Ruì, 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.
