The Noun Explanation of Pan Geng's Moving Yin

The earliest capital of Shang Tang is Bo. During these 300 years, due to the royal civil strife, foreign invasion, the Yellow River flood and other factors, the capital moved several times.

In BC 1300, the 20th king of Shang Tang, Pan Geng, ascended the throne. In order to change the unstable social situation, he moved to Yin in BC 1298, which eased social contradictions, got rid of political difficulties and made the Shang Dynasty prosperous.
