Pseudonym of the author of KR4k0274 Yīngsù Huā 罌粟花. The pen name identifies the author as a native of Yuanhe County 元和縣 (part of present-day Suzhou 蘇州, Jiangsu), whose studio name was Guanqiuzhai 观秋斋 (“Studio for Viewing Autumn”). No further biographical information has been established; the name does not appear in CBDB or standard Qing biographical dictionaries. The studio name’s autumnal melancholy is consistent with the patriotic lament that suffuses the novel.
