The achievements China has made today prove the one-child policy's effects on improving people's livelihood and speeding economic growth.

However, the implementation of the one-child policy also has its bottlenecks, though some families, such as ethnic minorities, can have more than one child, according to the policy.

Except for forced abortion, a punishment for disobeying the policy, female infanticide and under-reporting of female births are frequently seen as many Chinese families still prefer boys to girls, due to the influence of ancient patriarchal society.
