Qin: Respect the Legalist school, which is not the rule of law in our present sense, but a school centered on the will of the king. Burning books and burying Confucianism is the expression of Qin Shihuang's dissatisfaction with Confucianism. In fact, all Confucian classics were backed up in Epang Palace, which was later burned by Xiang Yu. In fact, those Confucian scholars who wanted to enfeoffment were all disgusted by Qin Shihuang, so they were killed.

Therefore, in fact, the ideological control of the Qin Dynasty was lax, and it only overemphasized the respect for the king. You can believe whatever you like and do whatever you like as long as it doesn't go against the king's will.

The influence is that Confucianism manages the country under the pretext of legalism, even if it is well managed, it will not last long. At the same time, it was also used by later kings as an excuse to strengthen ideological control.

Han: Before Emperor Wu of the Han Dynasty, the Han Dynasty ruled by doing nothing, and its ideological control was not strict. It just continues Qin's idea of governing the country, and the lower requirement is only to ask everyone not to rebel. Emperor Wu's exclusive respect for Confucianism is actually not the case, but the sage inside and the king outside. Therefore, the mainstream culture of the whole social environment respects Confucianism, but in various home schools, various ideas are still being passed down and developed.

Influence: It can only be said that the dominant position of Confucianism has been strengthened, the requirements for etiquette and law have become stricter, and the will of the monarch has been further emphasized ideologically.

Ming: The Ming Dynasty was an eight-part literati, so that all the literati in the Ming Dynasty became useless. But in fact, basically all the literati above the Jinshi, from the central government to local officials, don't believe in stereotyped writing, just as a means of Jinshi. The thought in Hongwu period of Ming Dynasty was the most harsh, which overemphasized etiquette and demanded three cardinal principles and five permanents. In addition, the literary inquisition also occurred in this period. However, after Ren Xuan, the thoughts of the Ming Dynasty became more and more open. During the period of Zhengde, Wang Yangming put forward the theory of mind to emancipate the mind. At the end of the Ming Dynasty, some philosophers put forward early democratic ideas.

Qing Dynasty: In fact, the Qing Dynasty continued the policy of Hongwu period in Ming Dynasty. The requirement of ideological death is stereotyped writing, and everything that jumps out is basically killing (note that most of the Ming Dynasty did not kill people by words). The literary inquisition was the most serious in Kanggan dynasties, so that after Jiaqing, the whole society became lifeless, and it was not until after the Opium War that China people's thoughts began to be liberated again. As for the impact, see for yourself.
