I’ve been watching for almost a year now as China has radically changed its child control policies from the infamous one-child policy to an almost-three child policy.

Thirty-five years of forced abortions, sterilizations, hysterectomies and outright murders of any children who managed to survive these procedures have drastically affected the Chinese family and kin structures on which Chinese culture rested. The South China Morning Post said the psychological trauma to Chinese society surpasses the impacts of other calamities, such as the Great Famine of the late 1950s and the Cultural Revolution of the 1960s and ‘70s.

So … now three children?

Last fall, the Wall Street Journal laid out some hints the government was throwing around. And there is a religion connection to this, so please stay with me.

BEIJING—A government-issued postage stamp of a happy pig family—with three piglets—has raised expectations that China may loosen its family-planning policy yet again.

China Post, the national postal service, on Tuesday unveiled its Year of the Pig stamp for 2019, prompting commentators on social media to speculate that the two-child policy is on its way out.

There is precedent: The ditching of the one-child policy in 2016 was foreshadowed by a Year of the Monkey stamp showing two baby monkeys.

Yi Fuxian, a scientist at the University of Wisconsin-Madison—and longtime critic of China’s birth policy—said the government is likely to go further this time. “It’s a clear sign that they are going to abandon all birth restrictions,” Mr. Yi said.

China’s fertility rate is one of the world’s lowest and nowhere near the replacement rate of 2.1 children per woman. The country disbanded its family planning commission last year.
