After the Manchurians entered the Central Plains, in order to stifle the national identity of the Chinese nation, they implemented the extremely brutal policy of "shaving hair and making it easy to wear".
This unreasonable and shameless act was resolutely resisted, and the Qing court was even more ruthless, ** tens of millions of innocent people, leaving a deep stain on their criminal acts. (Savage, keep your head without hair, leave your hair without your head).
There are many reasons for this. First of all, there have been examples of the extinction of the Chinese language in history.
After the Jin Dynasty fell to the Northern Song Dynasty, the Jurchen language was forcibly promoted. Many Han Chinese were forced to learn Xi Jurchen language in order to adapt to the situation. During the Southern Song Dynasty, Lu You's poems depicted the use of Hu language by children in the Eastern Capital.
Despite the efforts of the Jin rulers to promote the Jurchen language, in the end the Chinese language remained dominant, causing the Qing rulers to stay away from it.
Second, the Qing rulers were brutal and cruel, and lacked patience to promote meticulous language Xi. In contrast to simple and violent acts such as "shaving your hair and making it easy to wear", it takes patience and meticulous teaching to promote a new language.
The ruling class of the Manchurians lacked patience in this regard and therefore could not have succeeded in popularizing the Manchu language.
Again, whether the Manchurians had enough human resources to exterminate the Chinese language is a question.
The Manchu language is extremely complex and cannot be mastered by a large number of people in a short period of time. Moreover, the Manchurians had to enlist the support of Han scholars, which made it impossible for them to completely exterminate the Chinese language.
Finally, Manchu is not comparable to Chinese in terms of language level. If it is forcibly promoted, it will only cause the Han people to despise the Manchurians even more, and the dissatisfaction with the Qing court will escalate.
Today, the Manchu language has largely disappeared from the Manchurian rulers, while the Chinese language has been passed on to the Chinese nation because of its strong vitality.
