A 2010 Marketplace (American Public Media) profile of
[[entity-liang-zhongtang|Liang Zhongtang]], structured as direct interview
excerpts, quotes him discussing [[entity-song-jian|Song Jian]]: "I first
met him in the 1979 Chengdu conference. He could calculate population
numbers of a hundred years within an hour. At that time, who had
computers? Even the director of family planning office of State Council
was absorbed by the demonstration."

This is Liang's own testimony, independent of the 2016 Sixth Tone profile
already cited in the vault's claim-note on his 1979 proposal (see
[[claim-liang-zhongtang-1979-two-child-proposal-and-1985-yicheng-pilot]]),
corroborating the Chengdu location from a second source. It adds two facts
new to the vault: that Liang and Song were co-present at the same
conference (not merely two figures the historiography happens to discuss
together), and that Song's computational demonstration visibly impressed
the state family-planning establishment on the spot — consistent with,
and independent of, [[entity-susan-greenhalgh|Greenhalgh]]'s account that
[[entity-li-xiuzhen|Li Xiuzhen]] "was very excited about the projections"
at the same meeting (see
[[claim-greenhalgh-2005-names-li-xiuzhen-as-excited-by-song-jians-projections-at-chengdu]]).

The quote is Liang's retrospective account, in English translation, relayed
by an unnamed staff byline three decades after the event — a weaker
provenance than a named journalist's work, hence Tier 2 rather than Tier 1,
though the historical/biographical claim it supports (that Liang and Song
met at Chengdu) is uncontested and clears the sourcing floor at either
tier.

> [!note] Seek's commentary:
> Liang telling this story in 2010 reads less like a grudge and more like
> genuine, decades-later admiration — "he could calculate population
> numbers of a hundred years within an hour" is not what you say about a
> man you think stole your policy fight, it's what you say about someone
> who dazzled a room you were trying to persuade with careful demographic
> argument. Two different kinds of rhetoric lost to the same slide rule, or
> rather its absence everywhere except at Song's table.
