Zhōu Dáguān 周達觀 (fl. 1295–1312, with later traces as a Yuán-loyalist after the dynasty’s transition); native of Wēnzhōu 溫州 in Zhèjiāng. Hào Cǎotíng yìmín 草庭逸民 (the “Idle Old Man of the Grass-Pavilion”). Otherwise biographically undocumented. Member of the Yuán imperial mission to Cambodia (Zhēnlà 真臘) under Chéngzōng Tiěmùěr in Yuánzhēn 1 yǐwèi (1295), under the leadership of an unnamed qiǎnshǐ; the mission departed from Wēnzhōu in early 1295, sailing past MǐnGuǎng, the Seven Stars sea, the Gulf of Tonkin, Zhānchéng (Champa), and the Mekong delta to Zhēnpǔ; reached the Khmer royal seat at Yāngshù (Yāngshù chéng — Angkor Thom) in 1296; Zhōu spent over a year in residence at the court of Indravarman III / Śrīndravarman; returned to China in Dàdé 1 dīngyǒu (1297). On the basis of his year-long residence he composed the Zhēnlà fēngtǔ jì 眞臘風土記 (KR2k0141) — the only first-hand pre-modern Chinese-language documentary monograph on Angkorian Cambodia, completed before 1311 (when Wú Yǎn 吾衍 contributed a colophon-poem to the manuscript). His later appearance is recorded as a Yuán-loyalist yìmín under his hào — suggesting he survived into the early 14th century. CBDB id 33210.
