Suppose The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. Several walls were being built from as early as the 7th century BC, with some sections later joined together by Qin Shi Huang between 220 and 206 BC.
Can we infer that "The Great Wall of China is located in the southern borders of China."? Yes, no, or maybe?
