But Zhou Wuwang, who was over eighty years old, was still uneasy at this time, so he asked his brothers to spy on Wu Geng. These three brothers are Guan Shu, Cai Shu and Huo Shu, and they also have a nice name called "Three Supervisors".
After Zhou Wuwang's death, he advocated passing the throne to the son of King Wu, who later became king, and assisting him himself. This incident made me very unhappy, because as far as the inheritance of brothers and sisters is concerned, of course, the next top spot has to be done, but now he has been sent to Yin as a spy. So along the way, Guan Shu and the Duke of Zhou had bad blood, which eventually led to a fratricidal battle.
Guan Shu and Cai Shu joined forces with the staff of the Shang Dynasty to attack the Zhou Dynasty. On the side of the Zhou Dynasty, the Duke of Zhou personally went into battle, which lasted for three years. After the three-year war, the Duke of Zhou breathed a sigh of relief. This is a great event for the Yin people. It cannot be suppressed by force alone. We must fundamentally put an end to the troubles of the Yin people.
There are several main measures:
1. Create a dual capital system. Duke Zhou actively built Luoyi, the eastern capital, and moved some die-hards with strong nationality to the eastern capital, centralized management and political repression.
2. Let the Yin people be scattered and isolated.
3. I sealed my son Bochin to the most stubborn area in Shandong to deter him. And take other big countries (such as Qi, Yan and Jin) and small countries (such as Sui, Shen, Cai) as barriers.
What's more, when Zhou Wuwang was in office, he and Duke Zhou were golden partners, and the most awesome move was to create a feudal system of divide and rule and establish a country. It is worth mentioning that this is the real feudal system, and China entered the real feudal society at this time.
