First of all, during the Three Kingdoms period, Wei, Shu and Wu, as the rulers of the Han nationality, always maintained a strong military advantage over ethnic minorities. Needless to say, Wei, the strongest country, and Wu, the weaker country, also hit Hainan, and Shu won more than lost against that barbarian, so the cultural melting at this stage is the initial integration of Chinese culture.

Then the Jin Dynasty. The weakness and corruption of the Western Jin Dynasty gave the northern Hu people the opportunity to invade. After the Eight Kings Rebellion, the conference semifinals came to dispatch troops one after another, which was called "China in the Five Wild Areas" in history. A large number of Hu people invaded the northern land, burned and looted, and the Han people were displaced and fled to Liaodong, Liangzhou and Jiangnan areas, which gradually prospered these areas. Later, the former Qin briefly unified the north, but it was defeated when it invaded the Eastern Jin Dynasty, and the north split again until the Northern Wei Dynasty unified North China and entered the Southern and Northern Dynasties. The cultural integration in this period was dominated by Hu culture in the north and Han culture in the south.

Then in the Northern and Southern Dynasties, Emperor Xiaowen of the Northern Wei Dynasty vigorously promoted the localization of Hu people, and it was not until the Northern Zhou Emperor gave way to Emperor Wendi that the Hu culture of the Northern Han Dynasty really began to merge. The Southern Dynasties basically continued the state of the Three Kingdoms and the Eastern Jin Dynasty, and the Manchu and Chinese cultures were also in a state of mutual integration. During this period, due to the mutual attack of the Northern and Southern Dynasties, Han, Hu and Man could not get the upper hand, so cultural integration was the most prosperous period in the Northern and Southern Dynasties.

Then came the Sui Dynasty, which began with the abdication of the Northern Zhou Emperor in 58 1 year and ended in 589. Nanling was pacified in 5 10/year, and the north and south were unified. During the 37 years after the collapse of the Sui Dynasty on June18, cultural integration was in a relatively gentle period due to the short time. It is worth mentioning that the completion of the Beijing-Hangzhou Grand Canal has made the communication between the North and the South easier than before, and the cultures of Han, Hu and Man have really merged.

Then came the Tang Dynasty, during which China's national strength reached its peak. In the first half of the Tang Dynasty, the social economy was on the rise and the culture was advanced. Historically, China exported its culture and technology to neighboring countries, and the inclusive social atmosphere also provided an unprecedented exchange and integration environment for all ethnic groups living in Serbia since the five lakes and sixteen countries. The rulers also learned a lot from foreign civilizations. The Silk Road in the early Tang Dynasty also made it possible for cultural exchanges and integration between the Central Plains and the Western Regions. Until the Anshi Rebellion in the middle Tang Dynasty, it was the heyday of the integration of Chinese and Western cultures formed by Han, Hu and Man. However, after the Anshi Rebellion, the Tang Dynasty never wavered, and its national strength weakened, which slowed down the pace of cultural integration. In the late Song and Ming Dynasties, there was basically no prosperous period of cultural integration in China.

Off-topic, why didn't China culture merge on a large scale before Wei, Jin, Southern and Northern Dynasties and after Tang Dynasty?

The Han Dynasty, the predecessor of the Three Kingdoms, was stronger than the prosperous Tang Dynasty, and basically kept a high pressure on Hu Man. In addition, the rulers of the Han Dynasty believed in orthodoxy and looked down on Hu Man, so the culture of China in this period followed the culture of the Spring and Autumn Period and the Warring States Period, which was the real culture of China.

However, Song Ming Song, the cultural successor of China after the Tang Dynasty, was strong and weak, and the border was in a state of war for a long time, lacking a relatively long-term stable period, so there was less communication between China culture and the outside world, so there was no large-scale integration; By the end of the Song Dynasty, the inheritors of Chinese culture in the north were almost slaughtered, while the south was still struggling under the four-class division policy of Mongolian rulers, and there was no chance of integration at all. During the period of Yuan Renzong and Yuan Yingzong in the middle Yuan Dynasty, due to the implementation of the national policy of governing the country with Confucianism, Chinese culture and Mongolian culture had a brief integration, but this short integration was once again suppressed by the new rulers after the change of Nanpo.

In the Ming Dynasty, due to the hatred of Mongolian Yuan, the emperors of the Ming Dynasty maintained a state of relative resistance to the cultures of the northern minorities, and at the same time, the strengthened Great Wall became the dividing line between agricultural areas and nomadic areas, and between Han culture and nomadic culture. As a result, the Ming dynasty, which inherited most of Chinese culture, turned its attention to the world and spread Chinese culture to the world. This period can be said to be a period of initial integration of China culture and world culture;

For the Manchu Dynasty, this was not a fusion, but even a destruction of China culture. No dynasty has ever been so shameless as Manchu. Even when Mengyuan occupied China, there was a short period of cultural integration, while Manchu was completely destroyed. The process of destroying China culture in Qing Dynasty can be roughly divided into the following means: First, slaughter. All the rebels were slaughtered, and all those who spread China culture privately were killed. Only Yangzhou 10th, Jiading 3rd Butcher, Suzhou Butcher, Nanchang Butcher, Ganzhou Butcher, Jiangyin 81st, Changshu, Shazhen, Nanjing, Wuxi, Kunshan, Jiaxing, Haining, Jinan, Jinhua, Xiamen and Xiamen butchers are recorded in history. The massacres in Taigu, Qinzhou, Zezhou, Shuozhou, Guangzhou and Sichuan. And not only kill the Han people, but even slaughter ethnic minorities, such as Hui and Miao. Second, change history. Destroy all historical records that are not conducive to the rule of the Qing dynasty, and try to discredit the Ming dynasty and so on; Third, ban books. All books that are not conducive to the rule of the Qing Dynasty are listed as banned books for destruction. Here's a contrast. The Yongle Dadian compiled in the Ming Dynasty collected 7,000 or 8,000 kinds of ancient and modern books, while the Sikuquanshu compiled in the Qing Dynasty only had more than 3,500 kinds, which shows that the Qing Dynasty kept a strict check on China culture. The Manchu Dynasty consolidated its rule through these means, while China culture was in a state of semi-destruction, so that everything that has been passed down to this day was basically tampered with by the Manchu Dynasty, and the real China culture no longer existed.

I wonder how long this answer will last. After all, Baidu is TG's running dog, so be optimistic and cherish it. )
