Why is the Spring and Autumn Period and the Warring States Period a period of great social change in China?

China's privatization was strengthened in the Spring and Autumn Period, and China's autocracy was strengthened in the Warring States Period.

China in the Western Zhou Dynasty was a feudal federal system, but the authority of the federal government did not nationalize with the army, legislation and administration, but depended on the hegemony of the state where the federal government was located.

After Pingdong moved eastward, Zhou's power weakened, so China began a period of breaking nationalization and strengthening privatization.

Land: With the improvement of productivity, pot rice lost its meaning, so the land reform of household contract responsibility system was carried out.

Education: schools are weak, talents flow to neighboring countries, and they begin to give lectures and spread knowledge one after another, so private schools rise and educational rights are decentralized.

Military aspect: with the expansion of the war, the mode of aristocratic war is out of date, so many civilians joined the war and gave them the opportunity to make contributions.

Politically, the concept of being an official with excellent learning is deeply rooted in the hearts of the people, and many people of insight at the lower level have begun to enter politics. The rise of the literati class.

During the Warring States period, the political and economic reform of liberating productive forces began to stop, and the autocratic reform based on military reform began.

King Wuling of Zhao rode and shot in Hu suit, which made China enter the cavalry age, the speed and rhythm of the war accelerated, and the control over the surrounding areas gradually strengthened.

Military reform is a prominent feature of warring states.

Chu took the lead in implementing the county system.

Among them, Shang Yang's political reform is the most prominent. After Shang Yang's political reform, Qin established a set of mature fascist politics, became a militaristic country, and finally eliminated other vassal States.

Ten years later, the empire perished and Chu rose.

It was not until Liu Bang established the Han Dynasty that the Spring and Autumn Period and the Warring States Period really ended.
