The South Great Wall is the abbreviation of the South Great Wall of China. It is named for the only Great Wall in the South of China. It is located in Xiangxi Autonomous Prefecture of Hunan Province, so it is also called the Miaojiang Great Wall. The Great Wall of Miaojiang is situated in Fenghuang County. It is 190 kilometers long. It starts from Magpie Camp in Guzhang County, western Hunan Province in the north and goes south to Tingziguan in Tongren County, Guizhou Province, mostly on steep ridges. The purpose of the Great Wall of Miaojiang is not to resist the invasion of nomadic people, but to isolate the seedlings (Miao people who did not obey the court) and the mature seedlings (Miao people who obeyed the court) in order to prevent the emergence of seedlings. The Great Wall was built during the Wanli Period of the Ming Dynasty and was built with 42,000 silver appropriated by the court. In the late Ming Dynasty, the Miao people razed the side walls to the ground. The Qing government rebuilt a new wall on the old site of the side wall. The South Great Wall, with a top width of three feet, a bottom width of five feet, a height of about eight feet and a total length of more than 400 miles, was built in the 33rd year of Jiajing in the Ming Dynasty, that is, 1554 A.D. and has a history of more than 400 years.
