Senior Chinese Communist Party leader and economic planner (1905–1995), one
of the so-called "Eight Elders" of the post-Mao era and a chief architect
of China's planned-economy reforms, who — per Susan Greenhalgh's account —
proposed in late spring 1979 "the formulation of a law limiting couples to
one child."

Matters to this vault as a second, independently named political-will data
point: alongside [[entity-deng-xiaoping|Deng Xiaoping]]'s March 1979
birth-planning directive, Chen's proposal places top CCP leadership behind
one-child restriction before [[entity-song-jian|Song Jian]]'s cybernetics-
derived population projections reached policymakers in 1980 — part of the
evidentiary basis for Greenhalgh's own claim that the leadership was
already of one mind on the question.
