Two independent Tier-1 primaries give the author of the vault's 'Li Xiuzhen' article the surname 栗 (Lì), not 李 (Lǐ) — a plausible transliteration conflation

Both the PDF of the 1980 Renkou Yanjiu article and the journal's own citation-metadata page — including the citation_authors HTML meta tag, a machine-readable field unlikely to carry a simple display typo — give the author's name as 栗秀真, surname 栗 (Lì): "栗秀真. 当前计划生育工作的形势和任务 ——在第二次全国人口理论科学讨论会闭幕会上的讲话[J]. 人口研究, 1980, 4(1): 3-5." This is not 李秀珍 (Lǐ Xiùzhēn), the spelling in Susan Greenhalgh's citations and in the vault's own entity-li-xiuzhen page.

Liang Zhongtang's 2009 essay independently names the same official, in the same role, at the same December 1979 Chengdu symposium: "當時，坐在大會主席台的國務院計劃生育領導小組副組長兼辦公室主任栗秀珍 用一種欣喜的表情傾聽和關注李廣元的發言" ("At that time, the Deputy Head of the State Council Family Planning Leading Group and Director of its Office, 栗秀珍, sat on the conference's main platform, listening to and watching Li Guangyuan's remarks with a delighted expression") — also with the surname 栗, though with a different given-name character (珍 vs. the journal's 真; both read zhēn, plausibly an OCR or typesetting variant of one name rather than two different people, given the matching title and Leading Group role). Two independent sources — the journal itself and Liang's essay, neither citing the other — agree on 栗, disagreeing only with Greenhalgh's (and the vault's) 李. Since 李 (Lǐ) and 栗 (Lì) romanize identically as "Li" without tone marks, this reads as a plausible transliteration conflation in Western secondary literature rather than two different officials.
