Late-Yuán / early-Míng yílǎo (loyalist survivor) of Xūjiāng 旴江 (Jiāngxī). Zì Zǐshēn 子申; also known by his collection title Kōngtóng qiáoyīn 崆峒樵音. Reconstructed from internal evidence in his poetry (the SKQS editors of KR4h0089 Yuányīn yíxiǎng provide the principal biographical reconstruction):
(1) Served as military adviser in the Fújiàn shuàimù at the end of the Yuán, alongside his yīnjiā (in-law) 劉紹. Both records report that neither “realised his ambitions” there.
(2) Was an envoy to overseas islands (dǎoyí; probably Ryūkyū 琉球 or Korea 高麗) under late Yuán: his verse states “I at that time was dǎoyí xiánmìng, went out on diplomatic mission to barbarian zhàng”. Also a zhànglìshǐ (commissioner for zhànglì — possibly pestilence-region commissioner) to “the southern wilds”.
(3) Refused the Hóngwǔ summons of 1376 (bǐngchén); was imprisoned (cf. his bǐngchén yùzhōng yuánxī poem) and finally released in 10th month of bǐngchén (departing Lóngjiāng).
(4) Late verse — “xiǎngjiàn Níjīng yōng Xíngzài” — documents his continuing loyalty to the Yuán Shùndì in northern exile (post-1368).
His verse forms the first 8 juǎn of Yuányīn yíxiǎng (also titled Kōngtóng qiáoyīn); the SKQS editors describe his style as gāogǔ bùshī HànWèi yíyīn (“lofty and ancient, not departing from the HànWèi tradition”).
