The area from Bo to the Xia capital was flat, almost without any hills or rivers to stop them.
A tribe named Ge, which was geographically near to the Shang clan, did not worship their ancestors on a regular basis.
They ate the cattle and sheep which Tang had given them for sacrifices, and killed the children who sent the animals.
[1] When a few tribes started rebelling against Xia, Tang of Shang decided that the time had come.
Upon hearing of Tang's rebellion, Jie sent troops from the smaller territories of Gu, Wei, and Kuenwu.
Yi advised Tang to put off the fight for a year, then conquered Gu and Wei, and defeated Kuenwu.
Tang gave a speech, known historically as 'Tang's pledge',[3] before the two armies met in Mingtiao (present-day Xia County, North Anyi, Xiyun) around 1600 BC.
After conquering Kuenwu, Tang of Shang forced Jie into exile in Nanchao (present day Chao, Anhui).
