One correction applied this date, old wording preserved: the body said the attribution is not footnoted to Liang's own interview, 'cited elsewhere in the paper, footnote 6, ONLY for his stated reasons Yicheng was chosen,' and that the authors write 'independently of Liang's own self-presentation.' Both overstate the independence. Qin & Wang's reference list carries Liang, Z. (2014a), Studies on China's fertility policies (Taiyuan: Shanxi People's Press), cited at footnote 23, and Liang, Z. (2014b), China population problem (Beijing: China Development Press), cited on p. 934 for the argument that Yicheng is the only appropriate site among surviving two-child pilots — so Liang appears as a cited authority three times, not once, and the paper demonstrably draws on his own published account. What survives: the attribution sentence itself carries no citation, and it does not descend from the Whyte-Wang-Cai citation chain. The title's 'independently' is now qualified in the body to that narrower meaning rather than implying the authors had not read him."

Qin & Wang (2017) write: "In the spring of 1984, Liang Zhongtang, a
demographer in the Shanxi province People's Government Economic Research
Center, proposed a restricted two-child policy that would require couples
to marry later and wait longer before having a second child. In 1985,
Liang's advocacy for this policy convinced the provincial government to
allow Yicheng, a county in Linfen prefecture city, to replace the OCP with
the two-child policy proposed by the demographer."

This is a historical/biographical claim contested within this vault's
existing cluster: [[claim-whyte-wang-cai-cite-yan-wei-li-zhang-not-liang-for-yicheng-pilot]]
documents that Whyte, Wang & Cai's own citation chain to Yicheng never
names [[entity-liang-zhongtang|Liang Zhongtang]] at all, reaching the
county only through Yan Wei & Li Zhang's re-examination. Per the sourcing
floor, a contested historical claim escalates to Tier 1–2; Qin & Wang
(2017) clears that bar as a peer-reviewed journal article, and the
attribution sentence itself carries no citation at all — not to Liang's
own 2012 *Legal Weekly* interview (cited at footnote 6, for his stated
reasons Yicheng was chosen), not to Wei & Zhang (2014) — it appears as the
paper's own stated background, treating Liang's authorship as settled fact
within the demographic literature it surveys.

What the paper is not, however, is innocent of Liang's own account. Qin &
Wang cite two of his 2014 monographs elsewhere — Liang (2014b), *China
population problem*, for the argument that Yicheng is the only appropriate
site among the surviving two-child pilots (p. 934), and Liang (2014a),
*Studies on China's fertility policies*, at footnote 23 for a
baby-boom explanation of the late-1980s fertility rise — alongside the
interview at footnote 6. So "independently" here means that the
attribution does not descend from Whyte, Wang & Cai's citation chain and is
not itself sourced to Liang; it does not mean the authors wrote without
reading him.

This does not establish that Yan Wei & Li Zhang's own 2014 article names
Liang — Qin & Wang cite that article twice, once among the prior studies
comparing Yicheng's demographics (p. 930, with Gu & Wang 2009 and Wu 2014)
and once for the policy's operational rules (p. 932), but never in the same
sentence as the authorship claim. It establishes that at least one other
scholarly team studying Yicheng treats his role as proposer/architect as
uncontested background rather than disputed attribution.
