生二胎 have two children
Families will be allowed to have a second child if one of the parents is an only child.
如果父母一方为独生子女，则这样的家庭可以生二胎。
Allowing all couples to have two children at the present time would lead to high volatility in the infant population, putting too much pressure on public services.
目前还不能让所有的夫妻都生二胎，否则婴幼儿人口数量将会出现大幅波动，给公共服务设施带来巨大压力。
