Dànjū Kǎigōng 澹居鎧公
Late-Míng Chán abbot of Jìngshān 徑山 in Zhèjiāng, named in 德清 Hānshān Déqīng’s preface to Xìngxiàng tōngshuō (KR6n0102) as the figure whose request prompted Hānshān to compose that text at Jìngshān. The form “鎧公” — “Master Kǎi” — is a respectful sobriquet; the personal name 澹居 may be his studio-name. No further biographical details located.
