Jiuquan Satellite Launch Center (also known as Dongfeng Aerospace City) is built on an oasis in the Gobi Desert, with mountains in the west and rivers in the east. This is a treasure trove of geomantic omen personally selected by Marshal Nie Chuan. Jiuquan Dongfeng Aerospace City, built on June 20th, 1958, is the earliest and largest comprehensive rocket and satellite launch center in China. It is located at the northwest edge of the uninhabited Ejina Badain Jaran Desert, with a linear distance of more than 400 kilometers from the nearest Jiuquan City. At that time, it was named "Jiuquan" because missile satellite launch sites in various countries avoided using real addresses at that time, and because the launch site was located in the desert Gobi, it was difficult to choose a well-known place name, and Jiuquan was the closest to the launch center and was a famous city in history. In addition, in 1969, Alxa League broke away from the jurisdiction of Inner Mongolia Autonomous Region, and Ejina Banner was placed under the jurisdiction of Jiuquan City, Gansu Province. By 1979, Alxa League, including Ejina Banner, was restored to the jurisdiction of Inner Mongolia Autonomous Region.
