Girl group 4Minute participated in a child abuse elimination campaign.

On Feb. 16, 4Minute members posted on their group social media accounts a picture along with the message, "#donthitjusthug 'Don't Hit Just Hug' campaign. Don't Hit. Just Hug. Child abuse prevention campaign." 

In the picture, the words "Don't hit and just hug" are written. The campaign is a project launched by the city of Busan, South Korea's second-largest.

The 4Minute members decided to join forces with the campaign to spread awareness of the serious social issue.

Internet users who saw this commented, "So kind of them," "Such beautiful hearts," and "Let's all hug."
