What punishment will they get if they don't follow the one child policy?

The one-child policy, implemented in China from 1979 to 2015, imposed various penalties on families that had more than one child. Punishments could include financial penalties, loss of employment, forced abortions, and sterilizations. Local governments often enforced these measures differently, leading to significant regional variations in how strictly the policy was applied. Since the policy has been relaxed to allow for two and later three children, such punishments are no longer applicable in the same way.
