Looking at the map of the Southern Song Dynasty, it is only a corner of the south of the Yangtze River, and it is indeed not as large as the territory of Jin. However, in the official history, it is said that the Tang, Song, Yuan, Ming and Qing dynasties, and no one says the Tang, Jin, Yuan, Ming and Qing dynasties. Why? Because although the territory of gold is large, the positive trace of culture and civilization is not in gold. We know Sansu, Lu You, Liu Yong, Xin Qiji, how many do you know of the Jin Dynasty? And how much culture has been handed down?
Jin is the most successful dynasty of Sinicization. However, when the most successful imitations are put together with the real thing, people will still choose the real thing. The anti-Yuan and Song Dynasty of the Red Turban Army, and the Tang poems and Song poems summarized by the literati, all show everyone's recognition of the Song Dynasty.
Instead of arguing, trust authority. Even Emperor Qingchun, who considered himself a descendant of the Jurchens, said that the Song was orthodox, so what else was there to argue.
Beg to differ. As I said above, orthodoxy follows cultural civilization, not nation. Otherwise, how could Yuan and Qing be considered orthodox?
There is nothing to argue, orthodoxy is not up to you, nor is it for me to have the final say, but history has the final say.
Whether orthodoxy is orthodox or not depends on who has the right to speak. In the final analysis, it is the position of cultural people. History will always be cleared from the roots. The Yuan Dynasty once listed the Song, Liao, and Jin capitals as orthodox, but a few hundred years later, the Liaojin capitals became local forces. Just like now, some people boast that Kangxi Qianlong is the Holy Lord Mingjun. Hundreds of years later, when the boasters are gone, everyone will remember the Ten Days in Yangzhou, the Three Massacres in Jiading, the Literary Prison, the Treaty of Nanjing, the Treaty of Maguan, and the "Measure of China's material resources, and the joy of the country".
There has never been regionalism, the Yuan came to become a Mongol, and the invited became a Manchu. Even if Japan does come, it will end up being just a multi-Japanese clan. The main ethnic group of this land has not changed for thousands of years.
If Dajin can be like Yuan Qing, dominate the world and block the mouths of all readers, it may also become orthodox. It's a pity they didn't.
That's really the legacy. The three veins are also very clear. But orthodoxy is fighting for culture, not the national system.
The Jin Dynasty, and later the Yuan and Qing dynasties, were like what is now Israel. They can win countless times, but if they fail once, they will never recover. This is the innate inadequacy of a small number of people trying to dominate a large number of peoples.
To tell the truth, if it is only a Southern Song Dynasty, it is really reluctant to be orthodox. But there is also the Northern Song Dynasty with it. Together, they are counted as the Song, a prosperous and wealthy Great Song. Just like after the Anshi Rebellion of the Tang Dynasty, the emperor mastered the palm-sized place near Chang'an, isn't it still the Tang Dynasty?
The Eastern Jin Dynasty never faced a strong and complete northern regime, which is why no one questioned it.
The Jin State never regarded the Song people in the territory as ordinary people, but only as the object of looting. Therefore, the Song people in the north resisted continuously. In fact, the Yuan Dynasty was the same, except that he eliminated all the Han regimes.
I think whether it is orthodox or not, the two most important points are either you occupy the whole of China, or you have cultural inheritance and have the right to speak.
