In the seventh year of Xuanhe in the Northern Song Dynasty (the third year of Jin Tianhui, 1125), the Jin army divided into east and west routes and went south to attack the Song Dynasty. Wanyan Zongwang led the army from the east to attack Yanjing. Wanyan Zonghan led the army from the west to attack Taiyuan. On the east route, the Jin soldiers defeated Yanjing, crossed the Yellow River, and headed south to Bianjing (now Kaifeng, Henan). Seeing that the situation was in danger, Emperor Huizong of the Song Dynasty moved to the throne of Prince Zhao Huan and became the Emperor Qinzong of the Song Dynasty. In the first month of the first year of Jingkang (the fourth year of Jin Tianhui, 1126), Wanyan Zonghan led the Jin army to the east of Bianjing City, forcing the Song Dynasty to withdraw after negotiating peace. The Jin people demanded 5 million taels of gold and 50 million taels of silver coins, and ceded the three towns of Zhongshan, Hejian and Taiyuan. In August of the same year, the Jin army attacked the Song Dynasty in two ways; in the leap November, the two armies of the Jin army joined forces and captured Bianjing. Song Qinzong personally went to the Jin army camp to discuss peace and was detained by the Jin people. In addition to the two emperors Huiqin, a large number of Zhao family members, concubines, nobles, and court officials, a total of more than 3,000 people, went north to the Jin Kingdom. The public and private savings in Tokyo were wiped out. The Jingkang Incident led to the demise of the Northern Song Dynasty.
