You know what’s longer than the Great Wall of China? Apparently, the Great Wall of China! According to the BBC, two-year government study has now found that China’s symbol of “Get out! Intruders!” actually stretches a good 3,800km more than previously thought. The newly-discovered sections of the wall were built during the Ming Dynasty (1368 to 1644) and go from Hu Mountain in Lioning province to Jiayu Pass in Gansu province. The project will continue for another 18 months, presumably in an attempt to discover more wall and give marathon runners a loooot more ground to cover.
