Eight hundred years before and after the Zhou Dynasty was indeed the longest dynasty in the history of China. Saint Amethyst said that the Zhou Dynasty was "the longest 800 years". The reason why the Zhou Dynasty ruled for the longest time was that under the historical conditions at that time, the feudal system was implemented to manage the local areas, and the patriarchal clan system and the ritual and music system with the eldest son inheritance system as the core were formulated, which further consolidated the Zhou Dynasty's rule and social stability. Only with the development of the times, this system was gradually destroyed, which eventually led to the decline of the Zhou royal family until its demise. In the 13th year of King Huan of Zhou Dynasty (707 BC), the battle of Gui Ge broke out, which was a counterattack that Zheng Zhuanggong of Zheng defeated Zhou's allied forces in Gui Ge (now Changge North, Henan Province) in order to dominate the Central Plains in the early Spring and Autumn Period. It was also the beginning of the decline of the Zhou royal family and the rise of the vassal state after China entered the Eastern Zhou Dynasty. He disobeyed the emperor's orders and coveted and competed for hegemony. If the battle of Gege is the symbol, the actual power of the Zhou royal family in the world is only 339 years. Just like the Japanese emperor can be a series of generations. The longevity of the Zhou Dynasty came from the weakness of the Zhou Emperor. As a symbolic existence. At first, it was a practical operation to dress up the world and then hold the emperor to let the princes compete in the era of competition. So people are in no hurry to abandon this symbol. The Zhou Dynasty also survived for 800 years. Later centralized dynasties could not do this. Just like the Japanese emperor can be a series of generations.
