Huán Kuān 桓寬 (fl. ca. 73–49 BCE), zì Cìgōng 次公, was a native of Rǔnán 汝南 (modern Hénán). Recommended as Gentleman (láng 郎) under Xuāndì 宣帝 (r. 73–49 BCE), he rose to Adjutant to the Grand Administrator of Lújiāng 廬江太守丞. He has no full biography in either Hàn shū but is briefly noticed in Hàn shū yìwén zhì. He compiled the Yántiě lùn 鹽鐵論 (KR3a0006) — the dialogue-form record of the great Salt-and-Iron court debate of Shǐyuán 6 (81 BCE) under Zhāodì 昭帝 — long after the event itself, expanding the official transcript into sixty 篇 of polemic and counter-polemic between the xiánliáng / wénxué 賢良文學 of the empire and Yùshǐ dàfū Sāng Hóngyáng 桑弘羊 (taboo-form 桑宏羊 in SKQS). The standard scholarly view is that the Yántiě lùn is Huán’s literary recreation rather than verbatim record, intended as a Confucian indictment of the Wǔdì-period state-monopoly economy, even though by his own time the wine monopoly had been rescinded and only the salt and iron monopolies remained. CBDB does not contain him.
