The Spring and Autumn Period and the Warring States Period!

In 771 BC, the Western Zhou Dynasty fell. King Zhou You played with the princes in order to win praises from Si, and was eventually captured by the Dog Rong army. He died and the country was destroyed. Prince Yijiu succeeded to the throne with the support of Shenhou, Jinwenhou and other princes, and became King Ping of Zhou. The following year, King Ping of Zhou moved the capital to Luoyi to avoid the intrusion of dogs and soldiers. This was known as the Eastern Zhou Dynasty in history, and the Spring and Autumn Period and the Warring States Period began. This period lasted for more than 500 years, from the decline of the Zhou royal family and the struggle for hegemony among the princes, to the coexistence of the seven heroes and the reform and strengthening, and finally ended with the unification of the six kingdoms by Qin Shihuang. It witnessed China's dramatic transformation from a slave society to a feudal society, and also gave birth to ideas and culture that have influenced subsequent generations for thousands of years. In the early Spring and Autumn Period, after King Ping of Zhou moved eastward, the authority of the Zhou royal family plummeted. The era of "conquest of rituals and music came from the emperor" was gone forever, and was replaced by the turbulent situation of "conquest of rituals and music came from the princes". The patriarchal system gradually collapsed, and chaos such as "merger, direct lineage, two governments, and coupling of countries" occurred frequently. Internal strife continued in the Zhou royal family. King Huan of Zhou abolished the direct line and established a concubine, which caused the royal family to split. King Zhou Xiang's uncle colluded with the Quanrong rebellion, further weakening the royal family's ruling foundation. The various vassal states no longer obeyed the orders of the Emperor of Zhou, and instead conquered each other and annexed small states. The weak vassals were annexed by the big states one after another, gradually forming a pattern of Qi, Jin, Chu, Qin and other great states competing for hegemony. Qi was the first to rise. In 685 BC, Qi Gongzi Xiaobai ascended the throne as Qi Huangong after a battle for the throne. Regardless of past grudges, he appointed Guan Zhong as prime minister and implemented a series of profound reforms. Economically, Guan Zhong reformed the land tax system and levied taxes according to the quality of the land to prevent public land from becoming desolate. At the same time, he promoted the occupational hereditary system.
