Answer:
The one-child per family policy
Explanation:
To contain its surging population which rose to over a billion, the Chinese government issued the one-child per family policy in 1979. This policy required that every Chinese family would apply for a family planning certificate once the wife became pregnant for the first child.
This policy was effective in curbing the overgrowing population, however, this resulted in a labor force that lacked youths and a population that had more of aged people. In 2016, the Chinese government revoked this policy, thus allowing families to have up to two children.
Authors might have something else in mind for what they are writing about.
