The biggest one has been deflating their property bubble. It still remains woefully unaffordable but they have stalled the relentless rise in housing costs and have started to even bring them down in some cities. Their "housing is for living, not speculation" policy along with 3 red lines and directives to deleverage developer firms are all taking effect.

They banned for-profit tutoring to bring down the cost of raising children (but also ensure children have time to be children). These services are now offered by or in-cooperation with the state school system and no-longer teach the same subjects as are taught during normal school hours. i.e they basically converted it into educational after-school day-care that is strictly non-profit.

1 child policy was replaced by 2 child policy, then 3 and finally abolished. Ironically this was only ever applied to Han Chinese, minorities like Ughyrs have always had uncapped family sizes (another massively misunderstood fact about China but getting into it would just lead to downvote brigade by people that have never even been to China).

So yeah the plan is to reduce cost of living, drive down costs of having children in particular, allow people to have as many children as they want and soon I imagine we will see direct incentives to have children.
