Last week, some kids in the Ningxia city of Yongning were spotted getting some fresh air by playing on the roof of their 11-story apartment block.
Footage from a neighbor shows a pair of girls walking around on a ledge on the roof where a false step would see them fall to their deaths. One of the girls looks to be very young.
The property owner told reporters that the door to the roof had been left open in May following a fire safety inspection.
He added that a protective fence had now been installed around the roof to prevent this kind of thing from happening again.
