Since its launch in May 2016, the platform has helped solve the disappearances of 2,980 children.
The delivery workers cover a much wider range than common people in their activities, which gives them more chances to find missing children.
According to Eleme, their delivery workers have helped many families find missing children and elderly relatives in the past years.
