Why was it so hard to reopen the road to Gyirong Port?

Less than 5 meters in two hours. What made the road so difficult to reopen?

No road. Fast-flowing water. Unstable slopes. Massive rocks.

Watch how rescuers tackled one obstacle after another to reopen the route to the core area of Gyirong Port. #GyirongPort #Xizang #China #Rescue
