The Zhou Dynasty was a hereditary feudal dynasty in Chinese history after the Shang Dynasty, which was divided into two periods: the "Western Zhou" (1046-771 BC) and the "Eastern Zhou" (770-256 BC). The Western Zhou Dynasty was founded by Ji Fa, the king of Zhou Wu, with the capital of Haojing and Fengjing, and Luoyi was built during the Chengwang period; In the year of the Western Zhou Dynasty, after Ji Yijiu, the king of Zhou Ping, moved to Luoyi from the east of Haojing, it was known as the Eastern Zhou Dynasty in history. The Middle Eastern Zhou period is also known as the "Spring and Autumn Period and the Warring States Period", which is divided into two parts: "Spring and Autumn" and "Warring States". The Zhou Dynasty existed from about the 11th century BC to 256 BC, with a total of 37 kings in 30 generations, and a total of about 791 years. The Western Zhou Dynasty was the third and last hereditary slave dynasty in China, after which the Qin and Han dynasties began to become a unified state with a unified government from the central to the local level. Historical books often refer to the Western Zhou and Eastern Zhou as two weeks together.
