The Song Ning sect sent people to the Jin Kingdom to beg for peace, but at this time the Jin State occupied a completely favorable situation on the battlefield, and the Song Dynasty had no more chips to bargain, and the conditions put forward by the Jin State were:
If the Song Dynasty claimed to be a vassal of Jin, the Song State became a vassal of the Jin State, and the boundary between Jianghuai and Huaihuai was taken as the middle, which was basically the border between the two sides before the war.
If the Song Dynasty calls Jin a son, the Song Dynasty is commensurate with the father and son of the Jin Dynasty, although the Song Dynasty is shorter in generations, it still has relatively independent sovereignty, so that it is bounded by the Yangtze River, and the border is pushed south for hundreds of kilometers, and the Song Dynasty will lose a large amount of land. Moreover, it was necessary to attach conditions, the Song Dynasty would kill the main battle of Han Nongxin, and add another year coin.
If the Song Dynasty chose the first article, it would lose its sovereignty, and the Song Dynasty would be completely reduced to a vassal of the Jin Dynasty, and Song Ningzong would not be able to claim the title of emperor, but could retain more land. But if you choose the second one, Song Ningzong will still be your emperor, and the land north of the Yangtze River will be lost.
Han Nongxin was furious when he learned of Jin Guo's terms of agreement and decided to reorganize the soldiers and horses to fight again. This time, Song Ningzong was still very supportive of Han Nongxu, in order to call for resistance to Jin, Song Ningzong once again used Xin Abandoning Disease, the soul figure of the main war faction, and appointed him as the Privy Council Capital, but at this time, Xin Abandoned Disease was already very ill, but when he heard that the imperial court was going to use it again, Xin Abandoned Disease still struggled to get up, his eyes were full of tears, and he said repeatedly: "We must fight until Kaifeng!" But at this time, Xin Abandoned Disease could not stand up, and died of illness at home that night, until the death of Xin Abandoned Disease did not realize his wish to recover the Central Plains.
Han Nongxu was the staunchest main battle faction in the Ningzong Dynasty, and he also made great efforts for this, but Han Nongxin's luck always seemed to be not very good, and the failure of the Northern Expedition did not make him give up his determination to continue to fight again, in fact, although the Song Dynasty suffered defeat, it did not hurt the fundamentals, if it can be well planned, the Korean and Chinese officials can concentrate on resisting the war, and perhaps there is hope of victory.
The capitulation faction in the DPRK and China did not approve of Han Nongxin's Northern Expedition, and they believed that it would be good not to provoke the Jin people, so it would be good to live in peace and stability in the south. Now that Han Nongxu's Northern Expedition had failed, and the Jin people were still invading the south, this made the surrender faction completely angry, and they concentrated their firepower on Han Nongxu. These capitulation figures included Shi Hao's son Shi Miyuan and Song Ningzong's empress Yang Shi and other heavyweights.
Empress Yang and Han Nongxu were already at odds, and coupled with the provocation of Han Ting's capitulation officials, Empress Yang hated it even more and more, and she wanted to get rid of it quickly.
How did Empress Yang end up with Han Nongxu? This matter also has to start from Han Nongxin's niece Han Shi, who had made Han empress in order to win Han Nongxin, but Empress Han died of illness in 1200. Both Yang Guifei and Cao Meiren in the harem were Concubines of Emperor Ningzong, and when choosing who would be the empress, Emperor Ningzong of Song consulted Han Nongxin, who thought that Yang was too aggressive and difficult to deal with, so he suggested to Emperor Ningzong that Cao Meiren be made empress, but Emperor Ningzong thought that Cao Meiren's status was lower, or it was more appropriate to make the noble concubine. Yang Guifei eventually became empress, and she later learned that it was Han Nongxu who was opposing her entry into the Middle Palace, and she was determined to make Han Nongxin pay the price.
Empress Yang's brother Yang Cishan was closely related to Shi Miyuan, the son of the former chancellor Shi Hao, and had a bad relationship with Han Nongxuan, and Shi Miyuan had long had the intention of replacing him. Empress Yang secretly contacted Yang Cishan and Shi Miyuan to plot to get rid of Han Nongxin.
Xia Zhen was the official affair of the former division of the palace, he was the guard responsible for the safety of Han Nongxin, Shi Miyuan found Xia Zhen in advance and showed the "royal approval" to get rid of Han Nongxin, Xia Zhen was Promoted by Han Nongxuan, after seeing the "royal approval", he did not dare not follow, at the same time, Shi Miyuan also implied that Xia Zhen had a heavy reward afterwards, and if he did not carry it out, his life would not be guaranteed.
On November 3, 1207, Han Nongxu went to court as usual, and just after walking to the bend in the palace, Xia Zhen led people to take Han Nongxin to the yujin Garden, and Xia Zhen also showed Han Nongxu the "Imperial Approval" (the Imperial Approval was actually forged by the Empress), saying that Han Nongxu had lightly opened the army, so that the country was in danger, and the law was corrected on the spot.
After Han Nongxin was killed, Empress Yang only reported to Emperor Ningzong, who heard that Han Nongxu had been killed, and although he was very angry in his heart and almost unstable, he still pretended to be relaxed and said: "I know", at this time, Emperor Ningzong found that he could not control the government at all, and the empress and Shi Miyuan and others had taken control of the military and political power.
After Han Nong's death, the surrender faction represented by Empress Yang and Shi Miyuan accepted the jin people's proposal and demands, and sent Han Nong's head in a box to the Jin kingdom, and Song Jin signed the Jiading Peace Agreement.
Regarding the fact that Han Nong's head was sent to the Jin Kingdom, the chancellor Wang Jie strongly opposed it, believing that "Han Nong's head is not a pity, but the Great Song State is a pity."
