I can tell you that Zhou is just a title! Like the emperor, I won't go into details upstairs. Gou Jian's contemporaries were Zhou Yuanwang! Give you some information:
Zhou Yuanwang's name is Renji (BC? ~ 469 years ago). Zhou wangjing. The king's right to inherit after death. After seven years in power, he died of illness. The burial place is unknown.
In the year when King Jirentai of Joo Won? succeeded to the throne (475 BC), the history of China entered the Warring States Period. However, some scholars regard the division of Jin by the three schools as the beginning of the Warring States Period.
During Renji's reign, after Gou Jian, the King of Yue, attacked and destroyed the State of Wu, he led an army to cross the Huaihe River in the north and formed an alliance with the congresses of Qi, Jin, Lu and Song in Xu (now south of tengxian, Shandong). After the alliance, Renji was sent a tribute, and Renji also returned Gou Jian's meat for ancestor worship. He was named Bo, and he was recognized as the leader of the princes, and Gou Jian became the overlord for a while.
