Stock Photo - PRODUCTION - 18 January 2023, Vietnam, Hanoi: Do Duy Vi, co-executive director of Blue Dragon Children's Foundation, and a member of Blue Dragon's outreach team search for homeless children in an abandoned construction site that provides partial shelter from the rain. Tens of thousands of children live on the streets of Vietnam alone - no one knows exactly how many. They are threatened by pedophiles and human traffickers. But there are helpers who have escaped homelessness themselves. In search of the forgotten children of Hanoi.
