China’s policies for hiring disabled people must be very progressive.
The town of Bujia needed a bridge built, so they go get it designed, and search for a contractor to get the construction done. They end up hiring a contractor without verifying his credentials.
They later discover the contractor is blind.
The contractor took it upon himself to change the final design of the bridge, and “carried out the work only using a roughly drawn draft of the plan.” Which could mean he drew a sketch on a napkin while eating breakfast, and thought that would be good enough.
The parties involved were fortunate that when the bridge collapsed it was still in the construction stage, and the 12 casualities were injuries, not deaths.
