The president of Wenzhou's Cangnan County Social Welfare Institute has been suspended after photos of two orphaned children bound by chains were exposed by the media.

Huang Yitao, head of the welfare house, admitted the children were neglected after the photos sparked public outrage, according to the local civil affairs bureau.

The photos were taken by a volunteer who visited the welfare house during the Duanwu Festival from June 22 to 24. They show Guo Qun, 2, and Guo Cheng, 8, tethered to the back of a wooden chair.
