This time, the two countries are tired of war. First of all, neither country wants to fight. At that time, the Southern Song Dynasty had an advantage in the war. Yue Fei fought many battles and won many victories. It is said that Song Gaozong recalled Yue Fei with 12 gold medals in succession, and then made peace with Xu Jin. The Southern Song Dynasty reached a peace agreement with the State of Jin. The Southern Song Dynasty surrendered to the State of Jin and offered sacrifices to the State of Jin every year.
Why did the Southern Song Dynasty take the initiative to demand submission and peace when it had its own advantages? It depends on the political environment of Song Dynasty and Song Gaozong.
First of all, Song Taizu Zhao Kuangyin is a military commander, so he is very wary of military commanders. The Emperor of the Song Dynasty thought that civil servants wasted more money at most, and once military commanders did not obey, they might overthrow their rule, so the restrictions on military commanders in the Song Dynasty were relatively large. At that time, Yue Fei lost his gold and was on a roll, which made Song Gaozong a little worried. Secondly, Song Gaozong really didn't want to welcome Huidi and Qin Shihuang back. Emperor Gaozong's throne is ill-gotten wealth. At that time, Hui Zong had died of old age, but Qinzong was still alive. Once he was welcomed back to Song Qinzong, Song Gaozong's throne might be threatened. Therefore, for Song Gaozong, "shame, welcome back to the second emperor" is just a slogan, not his original intention.
Song Gaozong has been fighting since he acceded to the throne. According to legend, he was too scared to have children. In his mind, he hoped to live a quiet life for a few days, and with the replacement of the throne in Xu Jinguo at that time, it was possible to achieve peace. If there was no reconciliation at that time, even if the Song Dynasty had a military advantage and Yue Fei was brave and resourceful, the Song Dynasty could not have destroyed the State of Jin, and the cavalry of the State of Jin was useless in Jiangnan, and it was difficult for the State of Jin to destroy the State of Song.
As for how to evaluate it, I don't know, but reconciliation is at least beneficial to the people at that time!
