Incredible footage taken moments after the collision shows dazed passengers walking from the wreckage of the bus with the roof sliced off.
The 47-seater coach was traveling along a road in Hohhot city, China when the driver decided to take a shorter route by entering the low underpass.
Glass and debris were scattered all over the road after the incident. The metal roof of the bus was left hanging at the end of the vehicle after being peeled off like a lid of a tin can during the crash.
Miraculously none of 27 passengers or the driver were killed although two people were taken to hospital.
