Why did the Jin Dynasty call itself "Han Chinese" but the Southern Song Dynasty "barbarian"?

The Han nationality is the main ethnic group in China, a descendant of the ancient Huangdi and Yan Di tribes, and a descendant of the Chinese nation. "Han" originally refers to Tianhe and cosmic galaxies. But before the introduction of modern national consciousness from the west, few Han people in China called themselves Han people. Huaxia people, Zhongyuan people, China people, Qin people, Han people, Tang people and China people have different names in different historical periods.

In the history of our country, the Jin Dynasty claimed to be Han Chinese and called the Southern Song Dynasty "barbarian". The Jin Dynasty occupied the Yellow River valley, with its capital in Beijing. There are many Han people in the ruling area. Culturally, the Jin Dynasty completely absorbed the Han culture, and its national strength was strong and its economy developed. It just pretended to be authentic.

From the late Tang Dynasty to the establishment of the Yuan Dynasty, China was actually divided during the three or four hundred years. During this period, those who win the Central Plains may not win the world, but those who win the Central Plains should also declare orthodoxy.

The ethnic composition of people living in this land is already very complicated, but this place will get used to being called the land of Han people, and people living here will call it Han people.

Under the circumstances at that time, Jurchen established the Jin Dynasty, destroyed the Liao State, and then breached the capital of the Northern Song Dynasty, plundered the two emperors of the Northern Song Dynasty, and carved up the territory of the Northern Song Dynasty and the Jin Dynasty through negotiations. In this case, although the ruler was stronger than the Southern Song Dynasty, he could not win the Southern Song Dynasty. The Southern Song Dynasty had no choice but to pay tribute to the ruler.

Like any ethnic minority who occupied the Central Plains before, the Jin Dynasty initiated the sinicization mode of culture, and the ethnic integration was greatly accelerated.

Since then, the rulers have called themselves "Han people", and in the south, the Southern Song Dynasty, which was called the land of barbarians by the Central Plains people in ancient times, will naturally be called "barbarians".
