It's possible. At that time, it should still be possible. Let me throw a brick to attract jade. I can't remember a lot of information.

I remember that the national strength of the Southern Song Dynasty was good, with money, grain and soldiers. There is sound in China, and the main battle is available. At that time, the Jin Dynasty was in a period of indigestion, the outbreak period had passed, domestic resources could not keep up, and it was useless to effectively transform land into national strength. The domestic uprising is still going on. Lack of integration between ethnic groups. Lack of logistics, etc.

At that time, the Song Dynasty won two more wars. It is estimated that the Jin Dynasty will collapse because his country is too complicated. We can't suppress the surrender of Liao and Song. However, it is a pity that history has no ifs.
