People usually know what the Great Wall looks like, but they might not know which section was built over water. The Jiumenkou section of the Great Wall in northeast China of Liaoning Province is famous for just that. 

This section was 1,704 meters long in total, running from southern lofty mountains to the bank of the Jiujiang River. It then spans the river and forces its way up to the northern mountains. Owing to the strategic location, many battles took place here. Join CGTN to have a look at the beautiful stretch that has been developed into a scenic area.
