Jiuquan Satellite Launch Base was founded in June of 1958 and June of 10, located in Ejina Banner, Alxa League, Inner Mongolia. At present, the assembly launch site is located at 41.18 north latitude and 0/6 east longitude. 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 the flag, was restored to the jurisdiction of Inner Mongolia Autonomous Region.
