In December of the seventh year of Xuanhe, the gold lord Wu Beg bought the order to finish Yan Zonghan's advance into Taiyuan, and Yan Zongwang to advance into Yanjing, and the two roads would meet with Fenjing. The Jin army went all the way south, and the Song army fled in the wind. Emperor Huizong of Song was horrified and quickly issued an edict to his son Zhao Huan, who himself fled to Nanjing with 20,000 soldiers and horses.
The lords and factions in the court urged Emperor Qinzong to flee, but Li Gang tried his best to stop it, and Zhao Huan had no choice but to make a decision to defend it. Emperor Qinzong prepared the conditions for peace, appointed Li Gang as an envoy to the camp, and arranged all matters of city defense alone, and many lords and officials watched coldly, not obstructing or assisting. When the Jin army ascended the city, Li Gang led the army and the people to kill the enemy bravely, thwarted the Jin army's vigor, the Jin army could not break through the city, and the Song and Jin sides were in a state of confrontation.
The Soldiers and Horses of the Song Army arrived one after another. Fan Qiong led 10,000 troops, and the seed master Dao led Yao Pingzhong into the aid, claiming to be a million. The Golden Man was afraid and did not dare to plunder everywhere. Yao Pingzhong was ordered by Li Gang to attack the Jin camp at night and was defeated. Seed Master Dao said: This time it is defeated, tonight it is advisable to attack again at night, maybe it will be successful." Tomorrow night, a few thousand more people will be sent to attack at night, so that for ten days, the Jin people will be exhausted and will naturally retreat. Zhao Huan did not dare to use the Seed Master Dao, but instead blamed Li Gang and seed master Dao for the crime of defeating the army, and dismissed Li Gang and Seed Master Dao on the same day, expressing his apology to the Jin people. Ren Cai Mao defended the city on behalf of Li Gang. As soon as Cai Mao took office, he ordered the soldiers and civilians defending the city not to send a single arrow or stone to the Jin soldiers, so as not to anger the Jin people. The military and civilians were extremely angry. Chen Dong, a student of the Tai Dynasty, led tens of thousands of people to petition in front of the palace gate, requesting the removal of Cai Mao and the reinstatement of Li Gang and the Taoist priest. Emperor Qinzong had no choice but to summon the two back.
Li Gang and Seed Master Dao made a comeback, and the military and the people were overjoyed. The Jin army saw that the Song army was growing stronger, and had no choice but to return to the north. Seed Master Dao please take advantage of the Jin people's half-crossing attack on the half-crossing, but Emperor Qinzong will not allow it. Li Gang asked to send Jin Shi to escort Jin Shi away. Emperor Qinzong allowed it. Li Gang secretly ordered the Song army to follow and attack the Jin army, and the generals enthusiastically accepted the order. The chancellor Li Bangyan scolded Li Gang for not ordering the Song army to attack the Jin army, and ordered the Song army to return, and the Song army was indignant. Lü Hao asked for the enemy equipment in case the Jin army came again, but Qinzong did not listen.
Jin Junbei also returned, Song Junchen thought that there was nothing wrong in the world, Song Huizong Zhao Also returned from Nanjing, manchu Wenwu no one reflected, or put on a song and dance to level the world, without the slightest regret of the past. Li Gang wrote to him to strengthen his vigilance in case the Jin army returned. Zhao Huan did not accept. Ren Li Gang acted as an envoy to Hedong and drove Li Gang out of the imperial court to prevent him from obstructing his eyes. Zhao Huan ordered the disbandment of the Qin Wang army, and all other outspoken and outspoken officials who were in charge of the battle were driven out of the capital.
After Yan Zonghan attacked taiyuan city in September, the prefect Zhang Xiaochun and the deputy governor Wang Yu were killed. After Yan Zonghan and Yan Zongwang continued to divide into two large armies and go south. Zhao Huan was terrified and helpless, and Sun Fu, the head of the army, recommended the demon Guo Jingzhen to guard, saying that Guo Jing could perform the Liujia Method (demon technique) to capture the Second Marshal of the Jin Army. Zhao Huan died as a live horse doctor and appointed Guo Jing to guard the city. When the Jin army arrived at Kaifeng City, Emperor Qinzong ordered Guo Jing to fight, and Guo Jing shirked that he could not fight until the critical moment. The Jin army besieged the city, Guo Jing fled, and the Song Hundred Officials and civilians collapsed. Qinzong cried: "I regret not having to plant the Master's Tao, I can't regret it!"
Emperor Huizong of Song and Emperor Qinzong of Song were captured. The jin lord Wu Begmai made Zhao Tuo the Duke of Xiade and Zhao Huan the Marquis of Zhongxiao.
