Why did Zhou people "move their capital to Luoyi"?

Zhou people first lived in the west. After controlling the whole country, in order to rule the vast eastern region, the political center of the Zhou Dynasty needed to move eastward. In this regard, politicians at the beginning of this week have begun to consider. When they were still in Zhou Wuwang, they considered building a new capital in Luoyi, but due to the instability of the new Zhou Dynasty and regime, this plan was too late to be implemented.

When Duke Zhou was in power, King Wu's wish came true. In May of the fifth year of Wang, the election ended and the country was stable. After the Duke of Zhou and Wang Cheng returned from the East, they began to "move their capital to Luoyi".
