The ignorance by the people just walking past a injured child is simply horribleThe footage showed the van hitting the little girl, pausing briefly while she was under the vehicle and then driving off, running over her legs.
It then showed about a dozen passers-by, including cyclists, a motorcyclist and a woman and child, noticing the little girl lying injured in the street but walking on.
The child, Yue Yue, was taken to hospital for emergency surgery but pronounced brain dead on Sunday, the China Daily reported. http://www.bbc.co.uk/news/world-asia-pacific-15331773

I am pretty sure that helping out the girl and calling an ambulance would have not taken so much time from them

Kudos to the rubbish collector for helping her, but I guess it was too late.
