They schedule their children’s days in 15-minute increments. They scour online forums and swap tips on the most exclusive tutors and best sports coaches. Some even buy second homes next to the best public schools. Forget Tiger moms. These are China’s jiwa or “chicken” parents, who are known for their attentive — some say obsessive — parenting style. The term is used to describe aggressive helicopter parenting, and comes from an unproven Chinese medicine treatment dating back to the 1950s, in which someone is injected with fresh chicken blood to stimulate energy. Jiwa parenting culture, a relatively new phenomenon, is now in the crosshairs of Chinese authorities. At a time when the government wants to see families having more children and raising more future workers, it fears that hyper-competitive parenting pressures — combined with the meteoric growth of China’s private education sector, now worth billions — are deepening inequality and discouraging couples from having larger families, a priority of the country’s new three-child policy. As more parents complain about the burnout brought on by jiwa culture, there’s concern that the financial and emotional toll is making many reluctant to have a second, much less a third, child.
