三皇五帝
In the Three Sovereigns and Five Emperors period (五帝时期), about 2800BC, many tribes settled at Wuchuan. These included the Yunzhou (荤粥), Shefang (舌方), Tufang (土方) and Guifang (鬼方). The Yellow Emperor's war against Yunzhou was recorded in the Records of the Grand Historian by Sima Qian. During the Shang and Zhou Dynasties, King Wu of Zhou (武王) fought against the Guifang tribe many times, finally winning the battle after 3 years; an event which is recorded in the I Ching.
