Early-mid-Míng hereditary Yúnnán garrison commander and literary patron. CBDB id 127492. Third son of Mù Yīng 沐英 (1345–1392), Hóng-wǔ-era foster-son of Zhū Yuánzhāng and founding Xīpínghóu who pacified Yúnnán; brother of Mù Chūn 沐春. Mù Áng inherited family rank as Qiánguógōng and served as Yúnnán zǒngbīng (Commander-in-Chief of Yúnnán) for two decades in the Xuāndé and Zhèngtǒng periods, until his death in Zhèngtǒng 10 (1445).
In his later years he gathered a salon of literati at his Kūnmíng administrative seat (the Mùfǔ 沐府) and compiled the KR4h0099 Cānghǎi yízhū 滄海遺珠 (4 juǎn) — an anthology of contemporary Yún-nán-region poetry from his administrative-staff mùbīn and from local literati — the principal Míng documentary witness for early-Míng Yúnnán literary culture.
