Xu Jinguo is doomed. Are the descendants of Song Qinzong free?

After Jin Aizong ascended the throne, he encouraged agricultural production and reconciled with the Southern Song Dynasty and Xixia. Establish the loyalty and filial piety army directly under the central government, and employ famous anti-Mongolians such as monk Chen to defeat Mongolians in Dachangyuan (now Taichang Township, Ning County, Gansu Province) on 1228. Then the Jin army recovered a lot of land and brought the Jin dynasty back to life. And its ally Xixia was finally destroyed by Mongolia who returned from the Western Expedition in 1227 because of the decline of national strength in previous wars. In the same year, Genghis Khan died, 1229, and he was officially succeeded to Yuan Taizong by his third son, Wokuotai.

Since then, Mongolia has once again dealt with the rulers. 1230, wokuotai Khan initiated three-way gold cutting. Wokuotai Khan led an army across the Yellow River and headed for Bianjing. Yan led the East Route Army to Jinan, and his fourth brother led the West Route Army to attack Bianjing from Hanzhong along the Hanshui River. 1232, successfully detoured to Bianjing, Jin 'ai Sect and Pu 'a led the army to stop Dengzhou. At this time, Wokuotai Khan led the army to cross the river and sent Su Butai to attack Bianjing. He Da, Hong Yan, led an army to the north to help Bianjing, and joined forces with the Mongolian army led by Tuo Lei in Sansan (now southeast of Yuzhou City, Henan Province). The elite of the 8 Jin Army was defeated, and the famous Zhang Hui, Zhang Hui, Zhang Wei, Zhang Wei and Zhang Wei were killed and captured. Mongols besieged Bianjing and forced Jin Aizong to make peace. Then Jin Ting killed the Mongolian emissary, and Mongolia besieged Bianjing again.

Jin Aizong insisted on giving up Bianjing by the end of the year, fled south to Germany (now Shangqiu City, Henan Province), and Bianjing Shoujiang Cui Li fell into Mongolian hands. When he was chased, Jin Aizong fled to Cai Zhou, and the Mongolian army and camp. 1234 in the first month, Cai Zhou was in jeopardy. Jin Aizong didn't want to be the king of national subjugation, so he passed the throne to the commander-in-chief Wan Yan Cheng Lin and became the last emperor of the rulers. At this time, the city of Caizhou fell, Jin Aizong committed suicide, the last emperor died in the disorderly army, and the ruler fell.
