Qijia culture

The Qijia culture was an early Bronze Age culture distributed around the upper Yellow River region of western Gansu and eastern Qinghai, China. Johan Gunnar Andersson discovered the initial site at ''Qijiaping'' in 1923. During the late stages of the culture, the Qijia culture retreated from the west and suffered a reduction in population size. Qijia culture produced some of the earliest bronze and copper found in China. Extensive domestication of horses are found at many Qijia sites.

The archaeological site at Lajia is associated with the Qijia culture.
