Since Mongolia is the main fighting force, how can we shout the slogan of recovering Beijing?
Of course, the psychological thought must be "ready to turn against each other at any time", and even forming an alliance with Mongolia to destroy gold itself is a false proposition. The court of the Southern Song Dynasty never thought about this alliance, but was very wary of Mongolia, thinking that "this is the jurchen of that year." Preparations for the conflict between the Song Dynasty and Mongolia began very early-which also explains why the army of the Southern Song Dynasty was very tenacious in the face of Mongolia and fought for more than 40 years. In the battle of Fishing City, Mongo died, which directly led to the division of the Mongolian empire.
Unfortunately, Jurchen thought that the only way to get rid of the fate of national subjugation and extinction was to occupy the Southern Song Dynasty, which forced the Southern Song Dynasty to fight with all its might. In fact, the situation of unifying Mongolia and destroying gold was formed, which led to such a Covenant-after one year of alliance, the state of Jin perished.
In addition, for the powerful Mongolian empire, the attitude towards the Song-Mongolian alliance is hard to say. In a word, the Song-Meng alliance is a very short-lived interest alliance.
