#3 China
Along with being the most populated country in the world, China is also the most productive country (in terms of products, don't get me wrong here) on this globe.
The man force is driven crazily every single day in the minuscules of China. It seems as if people just love working here. Everyone is busy doing something or the other.

#2 The Bridge
Chinese workers have added another thing in the list of things they are proud of. The Sanyuan Bridge in Beijing has been rebuilt in a mind-blowing duration of 36 hours only. The genius engineers in the country made it possible.
Sanyuan Bridge is a major overpass on the northeastern stretch of the 3rd Ring Road of Beijing. The Airport Expressway, Jingshun Road (China National Highway 101) and the 3rd Ring Road are interlinked by the vital overpass.
