On Thursday, during the launch ceremony for the fourth updated version of Tuanyuan, the food-delivery website Eleme Waimai announced that the company and its 3 million delivery workers are joining the system.

Tuanyuan, an official online platform named after the Chinese word for reunion, releases information about missing children and was developed for the authorities by e-commerce giant Alibaba.

The Eleme app has connected with Tuanyuan, providing alerts about missing children to its delivery workers. Those workers within the scope of 100 kilometers of a disappearance will receive notifications the first time around, and then the information will be spread step by step to as far as 500 kilometers.

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.
