First of all, when and by whom was this empire founded? According to the existing historical records, she was founded in the fifth year of Zhenghe, Song Huizong (115), and was founded by Jin Taizu Yan Hong Akuta (Han Ming). But the question is, is this true? I should have said no.
Professor Liu Pujiang of Peking University has an article "Questioning the Truth of the Founding History of the Jin Dynasty", which raises many questions about the records of the founding history of the Jin Dynasty in existing historical materials, such as the relationship between Song and Jin Dynasties, the relationship between Liao and Jin Dynasties, and the exact establishment time. Most of the questions can only be questioned, but as for the founding time, Liu Jiaoshou clearly pointed out that the time for the Jin Empire to claim the throne with the Han system will never be five years. What year is it? He preliminarily concluded that this country may have been established in Zhenghe in 1978, and its title was "Jurchen" instead of "Jin", and it was changed to "Jin" in the fourth year of Xuanhe (1 122). As for the historical records of female tribes in the Jin history before the founding of the People's Republic of China, Liu Jiaoshou expressed a meaning in very polite language: basically nonsense. Finally, at the end of the full text, I left a sentence: "Of course, this is far from conclusive. We still need continuous efforts to completely restore the true face of the early history of the Jin Dynasty. "
Preliminary identification, possibility, possibility, or ... this is the description of the founding history of a famous and powerful empire in history by future generations. A sentence like that should be added to formal academic papers, and this country will give us a sense of nonsense as soon as it comes.
In fact, judging from the friendly relationship between Jin Taizu and Song Huizong, he probably didn't call himself emperor at all, but just established a vassal kingdom belonging to the Song Dynasty. It was his younger brother, Jin Taizong (Wu Qimai, Han), who betrayed the Song Dynasty, called himself emperor and posthumously granted him the title of Taizu. Later, due to Xu Jin's advantage in the war and diplomacy towards the Song Dynasty, he didn't want to mention the fact that the minister belonged to the Song Dynasty, and lied about the founding of Jin Taizu in order to bury some historical details of the founding of Di Chin.
