The origin of Jiuquan?

Jiuquan area is also one of the earliest areas where human activities appeared in China. More than 10,000 years ago, Jiuquan ancestors entered the Paleolithic Age. About 3500 years ago, Jiuquan people began to enter the Neolithic Age. In the Neolithic Age, the pre-democratic activities in Jiuquan were in Jiuquan Basin (including most of Suzhou District and Jinta County) and Dunhuang and Anxi Depression (including most of Dunhuang City, Anxi County and Yumen City).

About four or five thousand years ago, Jiuquan ancestors entered the era of human civilization. Siba culture is an important bronze culture in Hexi Corridor, with a large number of painted pottery.

After Emperor Wu of the Han Dynasty recovered Hexi area and established Jiuquan County, he set up two military passes, Yangguan and Yumenguan, in Dunhuang. After the Western Han Dynasty recovered Hexi region, four counties, Jiuquan, Zhangye, Dunhuang and Wuwei, were established successively, which were called "Hexi Four Counties" in history. In the sixth year of Ding Yuan (1 1 1), Emperor Wu of the Han Dynasty established Dunhuang County to the west of Jiuquan. In 8 AD, Wang Mang proclaimed himself emperor, following the county system and establishing Fuping County (formerly Jiuquan County) and Dunde County (formerly Dunhuang County).

Jiuquan is a prefecture-level city in Gansu Province, located between Altun Mountain, Qilian Mountain and Mazong Mountain at the western end of Hexi Corridor in the northwest of Gansu Province, with a latitude of 38 09 ′ ~ 42 48 ′ north latitude and a longitude of 92 20 ′ ~ 65 438+000 20 ′ east longitude. Except a few in the north bordering Mongolia, most of the west and south are adjacent to Alashan League and Xinjiang Uygur Autonomous Region in Inner Mongolia.

Jiuquan was one of the four counties in Hexi in Han Dynasty. Since ancient times, it has been a traffic fortress from the Central Plains to the Western Regions and an important town on the Silk Road. The terrain is high in the south and low in the north, tilting from southwest to northeast. From east to west, it is the main peak of Qilian Mountain, Taolai Mountain, Daxue Mountain, Maye Mountain, Altun Mountain, Danghe Mountain and Saishiteng Mountain, which belongs to continental arid climate.
