The Great Wall relic of Han Dynasty (Chinese: 漢代長城遺址) is located 5 kilometers west of Yumenguan (玉門關), Dunhuang (敦煌), Gansu (甘肅) Province, China. The relic has almost 2,000 years of history but is still well preserved.
After Han Emperor Wu (漢武帝; 141BC - 87BC) occupied the Hexi Corridor (河西走廊), he gave orders for the construction of the Great Wall so as to consolidate the safety of Gansu.
The wall is around 402 meters long, and the remaining ramparts have a height of almost 4 meters, a bottom width of 3 meters, and a top width of 1.5 meters.
Due to natural erosion, the coating of the wall has long been peeled out, so you can see the structure of the wall clearly. Sand and plants were added by putting one on top of another, tough as steel and concrete.
Gobi Desert (Mongolian: ᠭᠣᠪᠢ) is a large desert or brushland region in East Asia. It covers parts of Northern and Northeastern China and of Southern Mongolia.
Gobi Desert is bounded by the Hexi Corridor and Tibetan Plateau to the southwest, it is notable in history as the location of several important cities along the Silk Road.
