Alibaba-made app helps find 611 missing Chinese children
A mobile app developed by Alibaba helped Chinese authorities recover 611 missing children last year. The 'Tuanyuan' app, which means 'reunion' in Chinese, sends push notifications with photos and descriptions to users who are close to the location of a child's disappearance. The notifications are sent to users farther from the location of the disappearance till the child is found.
