A six-year-old Chinese boy who had his eyes gouged out does not know he has been blinded and asks his family why the sun has yet to rise, state media reports.

The boy, surnamed Guo, was found covered in blood in the northern province of Shanxi after he went missing while playing outside, Chinese media reported previously.

His eyes, gouged out by an attacker, were recovered nearby, a police officer in Fenxi county who declined to be named.

The boy was being treated at an eye hospital and was not yet aware he has been left blind for life, the Beijing Youth Daily said on Wednesday.
