A volunteer in Suzhou took tens of thousands of photos in seven years to reunite 7 families. Zhang Yanguo, who is in his fifties, finally met his mother with the help of volunteers looking for relatives.

Zhu Xueming, 65, is a native of Zhenze Town, Wujiang District, Suzhou City, and once served as the deputy mayor of the town. After retiring, he loved photography and liked to shoot everywhere with his camera on his back.
