[[claim-whyte-wang-cai-and-liang-disagree-on-yicheng-pilot-start-date]]
records a direct, five-year conflict: Whyte, Wang & Cai's 2015 essay dates
the Yicheng, Shanxi two-child pilot to 1980 (attributing the finding to Yan
Wei and Li Zhang's 2014 re-examination), while the vault's existing Liang
Zhongtang seed note, sourced to a 2016 Sixth Tone profile of Liang himself,
dates it to July 1985. The companion note
[[claim-whyte-wang-cai-cite-yan-wei-li-zhang-not-liang-for-yicheng-pilot]]
separately records that neither of Whyte-Wang-Cai's two citations of the
Yan Wei/Li Zhang analysis names [[entity-liang-zhongtang|Liang Zhongtang]]
as the pilot's architect at all.

## Why it matters

Both conflicts are load-bearing for how the vault describes the Yicheng
pilot going forward — "a two-child alternative Liang ran from 1985" and "a
county-level program documented running from 1980" are not the same claim,
and a biographical anchor note currently rests on the weaker (Tier 3,
decades-later, self-reported) of the two dates without yet being tested
against the stronger one.

## What would answer it

- A direct read of Yan Wei and Li Zhang, "Re-examination of the Yicheng
  Two-Child Program," *The China Journal*, No. 72 (July 2014), pp. 98-120 —
  paywalled at the publisher, no accessible copy located as of 2026-10-09.
  This single article would settle both questions at once: what start date
  the county-level record actually supports, and whether the re-examination
  names Liang as the program's architect or treats it as an institutional
  record with no individual credited.
- Failing that, a second independent account of Yicheng's start date (a
  different scholar, a different venue) to triangulate against either
  existing claim.

## Candidate next moves

- Check whether Yan Wei or Li Zhang have an accessible working-paper
  version, author's-site copy, or a later paper restating the same finding.
- Check Tyrene White's *China's Longest Campaign* and Thomas Scharping's
  *Birth Control in China 1949-2000*, named in Whyte-Wang-Cai's footnote 4
  as further general sources on the pre-1980 campaign, for any independent
  mention of Yicheng or Liang Zhongtang.

## Progress log

- 2026-10-12: Question raised at promotion of
  10-inbox/raw/2026-10-09-what-genuinely-connects-liang-zhongtang-proposed-a-two.md.
  Neither candidate next move attempted yet. Still **open**.
- 2026-10-18: Partially answered, not closed. A batch session found Qin &
  Wang (2017, *Demographic Research* 37:30), a peer-reviewed, Tier-1
  econometrics paper independent of both contested parties, which (a)
  independently dates the Yicheng pilot to 1985, matching Liang's own
  account against Whyte-Wang-Cai's 1980, and (b) independently names Liang
  Zhongtang as the pilot's proposer, treating his authorship as settled
  background. Neither finding reads Yan Wei & Li Zhang's own 2014 text —
  still paywalled, still the one document that would actually settle what
  that article itself says about either the date or the authorship. Still
  **open**.
