"I no longer felt lonely. There were so many volunteers helping us find our children - I felt very touched by this," Jingzhi says. There was another benefit too: "I thought even if my child is not found, I can help other children find their home."
Then in 2009, the Chinese government set up a DNA database, where couples who have lost a child and children who suspect they may have been abducted can register their DNA. This was a big step forward, and has helped solve thousands of cases.
Most of the missing children Jingzhi hears about are male. The couples who buy them are childless, or have daughters but no sons, and most of them come from the countryside.
Through her work with Baby Come Home and other organisations over the past two decades, Jingzhi has helped connect 29 children with their parents. She says it's hard to describe the feelings she went through when she witnessed these reunions.
"I would ask myself: 'Why couldn't this be my son?' But when I saw the other parents hugging their child, I felt happy for them. I also felt that if they could have this day, I definitely could have this day too. I felt hopeful. Seeing their child go back to them, I had hope that one day my child would return to me," Jingzhi says.
