Zhou Gong's regency led to the co-existence of two kings in the early Zhou Dynasty, and real situation was the separation of political power and religion power. Zhou Gong's was the leader in religion realm, yet he took over the political power in the late reign of King Wu. Zhou Gong's regency caused himself under suspicion by the King family since his governance made no clear distinction between political power and religion power. In order to solve this problem, Zhou Gong relocated the Capital to Luoyi, and devoted himself to making rituals and music with the purpose of making the separation of political power and religion power more obviously-identified. Zhou Gong's such efforts had produced an far-reaching revolution in social system and ideology and culture.
