Into the slave society-about 2 1 century BC, the Xia dynasty was established.

Entering the era of enfeoffment (so-called feudal society in foreign countries)-about 1 1 century BC, the king of Wu destroyed Yin, and the Western Zhou Dynasty began.

Slave society began to disintegrate, and the county system (feudal society mentioned in primary and secondary schools) was being established. -In 770 BC, Zhou Pingwang moved the capital to Luoyi, which began in the Spring and Autumn Period of the Eastern Zhou Dynasty. Especially in the first 403 years, the state of Jin began to be chaotic, and the three-point incident of the state of Jin marked the beginning of the Warring States period. China is undergoing drastic changes, and China soon entered the feudal society.

Officially entered the era of county system (feudal society)-22 1 year BC, the king of Qin was renamed the first emperor and established the county system.

Confucianism officially became the thought of governing the country (in fact, it was overseas Confucianism, which was impacted by Confucianism and Buddhism during the Wei, Jin, Southern and Northern Dynasties, but Confucianism, as the thought of founding the country, passed on for thousands of years until the May 4th Movement)-In BC 134, Emperor Wu of the Han Dynasty issued a letter to seek a general plan for governing the country. Dong Zhongshu, a Confucian scholar, systematically put forward the theory of "the unity of heaven and man" and "the unification of the world" and the proposition of "ousting a hundred schools of thought and respecting Confucianism alone" in his famous "Countermeasures for Giving Virtue".

Finally got rid of the monarchy and entered the era of bourgeois republic. Nominally, the citizens of the Republic of China were the masters of the country-1911year, Wuchang Uprising, the Qing emperor abdicated the following year, and the Republic of China was founded.

Before that, it was a centralized feudal dynasty, and the Republic of China was nominally a Republic, but actually a dictatorship.

1949, entered the new China period, a people's democratic Republic.
