First of all, we must admit that the military strength of Jin State is stronger than that of Southern Song Dynasty. The feudal rulers of the Southern Song Dynasty were eccentric. They just want to defend their territory in the south, but they don't want to recover lost ground. In the history of the Song Dynasty for many years, the military strength of the Song Dynasty was always weaker than that of the Jin Dynasty. Although the Northern Expedition was carried out during the period, the idea was dismissed just after encountering some difficulties and setbacks. The Southern Song Dynasty imperial court never returned to the northern region it dreamed of.
Jin Guo only occupied the northern region militarily, but they did not form a political, economic and cultural system and did not really integrate into the northern region. And with the passage of time, the advantages of the Southern Song Dynasty imperial court gradually emerged. They have a complete political system and a prosperous economy. The longer the time, the stronger the power of the Southern Song Dynasty court. The internal power struggle in the state of Jin is fierce, and the internal contradictions have reached irreconcilable levels, and the combat effectiveness has been completely lost.
The ruling car of the Southern Song Dynasty is still dreaming of its own spring and autumn in the southern region. It is an inevitable trend that the world will split for a long time, and it will split for a long time. The thought of being partial in the Southern Song Dynasty is self-indulgence, which will be eliminated by this era. The Southern Song Dynasty and the State of Jin were doomed to be unable to board the ships of the new era.
