Poorly worded slogans that advocate family planning in China are undergoing a makeover as the National Population and Family Planning Commission launches an in-depth analysis of the current slogans, the People's Daily reported.

Old slogans, such as "Raise fewer babies but more piggies" and "Houses toppled, cows confiscated, if abortion demand rejected," will be replaced by new ones that convey the policy better.

The family planning policy, which took effect in 1979, requires families to have only one child. Families in ethnic groups are exempt.
