Reasons for the decline of kanggan from prosperity

The reason for the prosperity of Kanggan was that it experienced a long period of war in the late Ming and early Qing dynasties, and gradually stabilized during the Kangxi period, and production began to resume development. So the prosperous time of Kanggan appeared when Kangxi Yongzheng Qianlong san huang arrived.

There are many reasons for the decline from prosperity: 1. Politically, the Qing dynasty practiced feudal autocracy and began to corrupt. In the central government, big corrupt officials, represented by gentry, have appeared, and in local areas, there is a saying that "a magistrate is clear in one year, and a hundred thousand snowflakes are silver". 2. Economically, the Qing government implemented the traditional policy of attaching importance to agriculture and restraining commerce (this policy was deeply rooted in China for more than 2,000 years), which hindered the development of capitalism in China and slowed down the development of commodity economy.

3. In terms of foreign relations, due to the needs of the Qing Dynasty. In order to prevent the contact between Chinese and foreign anti-Qing forces and the infiltration of western colonialism, the rulers of the Qing Dynasty adopted a closed-door policy. Although the closed-door policy has a certain self-defense function against the invasion of western colonists in a certain period of time, it is a passive and backward policy after all. The closed-door policy can't weaken the strength of western capitalist countries, but it hinders their own development, which makes China lose the initiative in foreign trade, and the rulers are ignorant and arrogant, which cuts off the scientific and technological exchanges between China and foreign countries, hinders the development of productive forces and social progress, widens the gap between China and the West, and creates a passive situation in modern China.

In terms of educational ideology and culture, the rulers of the Qing Dynasty implemented the backward educational system and still used the backward method of stereotyped writing to select talents. Daxing literary inquisition, strengthening ideological autocracy.

5. In other respects, during Jiaqing period, a large-scale peasant uprising-An Baili Uprising took place. Although the uprising was suppressed by quilts, the treasury of the Qing government was exhausted.

To sum up, after more than 100 years of prosperity, the Qing Dynasty began to decline.
