Lí Zé 黎崱 (Vietnamese: Lê Tắc), zì Jǐnggāo 景高, hào Dōngshān 東山, fl. 1284–1340. Born in Áizhōu 愛州 (the Trần-period province of Thanh-hóa in north-central modern Vietnam) into a family of Chinese descent — they traced their ancestry to the Eastern-Jìn Jiāozhōu cìshǐ 交州刺史 Ruǎn Fū 阮敷, generations resident at Áizhōu. As a child he was adopted by the Lí 黎 (Lê) family and took the surname Lí. He passed the Tóngkē 童科 (juvenile examination) at nine, and rose under the Trần dynasty of Đại Việt to shìláng 侍郎; he then transferred to the staff of 陳鍵 Trần Kiện, Jìnghǎijūn jiēdùshǐ 靜海軍節度使. In Zhìyuán 至元 24 (1287), during Khúp̌ilai 忽必烈’s second invasion of Annam, Trần Kiện led Lí Zé and others to surrender to the Yuán expedition. Annamese resistance forces intercepted the surrendering party; Trần Kiện died of his wounds. Lí Zé survived and made his way to the Yuán court, which awarded him the rank of Fèngyìtàifū 奉議大夫 and settled him at Hànyáng 漢陽 (modern Wǔhàn). He lived out his life in Yuán exile, dedicating himself to historical and scholarly work. His magnum opus is the Ānnán Zhìlüè 安南志略 KR2i0020 in 20 juàn (the Sìkù recension transmits 19) — the earliest surviving systematic Chinese-language gazetteer of Đại Việt — composed in part to vindicate the name of his patron Trần Kiện, with prefaces by the senior Yuán scholars Yuán Míngshàn 元明善, Xǔ Yǒurén 許有壬, and Ōuyáng Xuán 歐陽玄 dated to the 1330s and 1340. CBDB id 111996 gives fl. 1284. The catalog meta of fl. 1300–1339 captures the productive years of his Yuán residence.
