politics
After the Qing army entered the customs, the Qing government once put forward the slogan of "Man and Han families take care of each other", so a large number of Han people were hired as officials. Beijing officials are equally divided between Han and Manchu, and foreign officials are more Han than Manchu. However, most of the real power positions are in the hands of Manchu nobles, and Han people are in a subordinate position in the ruling class. All Han people have to pay for Manchu. Therefore, after the Qing army entered the customs, the vast majority of Han people were essentially enslaved by Manchu nobles. After entering the customs, after accepting the political system of the Central Plains Dynasty (mainly the Ming Dynasty), the Qing Dynasty strengthened its imperial power. The establishment of Yong Zhengdi Military Department marks the peak of China's absolute monarchy. This made the imperial power, which was relatively weakened in the middle and late Ming Dynasty, expand again, which was another great strengthening of China's autocratic centralization after the early Ming Dynasty, with the deepest degree, the longest duration and the worst influence on later generations.
economy
During the Qing army's entry into the customs, the Qing army carried out bloody repression in various parts of China, which brought great pain to the people of China, led to a sharp drop in the population of China, and also caused great damage to China's social economy and social productivity, seriously destroying the budding capitalism in the middle and late Ming Dynasty. China's economy didn't basically recover until the Kangxi period. After the Qing army entered the customs, Manchuria was still in the stage of slave society. The productivity and mode of production are backward, so the Manchu people vigorously promoted the enclosure movement in the Gyeonggi area of China, and a large number of Han people became slaves (that is, slaves), and China society even had a tendency to regress to a slave society. However, after the Qing army entered the customs, the Qing rulers ordered to stop enclosure and vigorously develop agricultural production. Therefore, China's economic base has not changed in essence, and its social form is still a feudal society. But this has seriously hindered the development of capitalism in China, which is a retrogression. Manchu asked Han people to shave their heads with "suncus murinus tail".
culture
After the Qing army entered the customs, the Manchu government violently carried out a series of ethnic oppression policies, such as shaving hair and changing clothes, and forced Han people (especially men) to shave into Manchu's "suncus murinus tail" style (which later became semi-bald and semi-braided), instead of wearing Hanfu, which lasted for thousands of years, to wear nomadic clothes. Later, in order to maintain their alien rule, China ancient books were deleted at will. "There's really no place in Wenyuan that won't be ravaged" [14], which has caused great disaster to China culture.
think
After the Qing army entered the customs, the Manchu rulers set up a literary inquisition to suppress the resistance and progressive thoughts of the Han people and beheaded the brilliant enlightenment thoughts since the end of the Ming Dynasty.
According to this, some people think that the entry of the Qing army is the most important reason why modern China lags behind the world.
