The Great Wall you may not know about

Shizuishan in Northwest China's Ningxia Hui autonomous region is home to many Great Wall segments that are not widely known. 

Built during Emperor Jiajing's reign during the Ming Dynasty (1368-1644), the Great Wall section in Shizuishan's Dawukou district extends more than 43 kilometers. It has 18 smoke towers and 75 wall fragments. 

Li Zhigang, a resident of Shizuishan, noted that the wall in this area played an important role as a military bulwark against the Tartars. 

Li used drones to record a variety of views of the Great Wall section.
