The area of Qilihe district has been inhabited since the
Neolithic era. In 1083, a fort was built at present A'gan Town. In the 1940 it was part of
Gaolan County, and two towns were located at the present urban centre, Huaqiao (握桥镇) in the east and Bingping (丙屏镇) in the west. In 1949, these two towns became the eighth and ninth districts of Lanzhou, which were renamed fourth and eighth district respectively in 1953. In 1955, the fourth district became Qilihe District. The name of the district is derived from a stream (hé), located seven (qī)
li from downtown Lanzhou, and between the two former towns. == Demographics ==
