Shanghai is one of the busiest cities in the world, but that didn’t stop one mail courier from traipsing through the downtown area with massive wooden counts. The messenger is weaving through traffic like a pro as he transports box after box after box. It’s quite a sight to see–and also induces some cringes.

There are too many boxes to count, but obscured vision doesn’t seem to faze the delivery driver. It takes a lot of bravery to trudge through Shanghai with partial vision, but it seems to be the norm among couriers.

This past July, a video of a female courier piling over 200 boxes on her tricycle also went viral.
