SHENZHEN: Holding aloft banners and posters, more than 30 parents of missing children in Dongguan staged a march on Wednesday to draw the government's attention to their plight.

The parents, mostly migrant laborers working in the manufacturing hub of South China's Guangdong province, claimed that more than 500 boys went missing last year alone and at least 1,000 were abducted since 2007, the Guangzhou-based newspaper New Express reported.

The parents planned to appeal to the municipal government of Dongguan on Wednesday morning, seeking help with rescuing their kidnapped children.
