Update 1: 5. An analysis of the disadvantages of the strategy of uniting Jin to destroy Liao in the late Northern Song Dynasty.

"Tai Xue Chao" occurred in the first year of Jingkang in the north (1 126) and was initiated by Xue students. The reason for the initiation was that the Prime Minister dismissed Li Gang, a hawk general, and made peace with the Jin people. During the reign of Emperor Huizong of the Northern Song Dynasty, Evonne preferred courtiers and did not participate in political affairs. However, the border incident was light, and the rulers destroyed Liao, which eventually led to the invasion of the rulers. In December of the 7th year of Xuanhe in Hui Zong (A.D. 1 125), nomadic people broke into the territory separately. Mr. Chen Dong, a former student, accused Cai Jing, Tong Guan, Wang Fu, Liang Shicheng, Li Yan and Zhu Mian of committing treason, calling them six thieves and asking the emperor to order them to be executed. The emperor ignored it. In the first year of Jingkang, Jin people forced Kaifeng. Li Bangyan, the prime minister, was afraid of nomads from the army, so he dismissed Li Gang and Zhong Shidao, the main battle generals, and decided to cede territory for peace. Chen Dong heard the news, led the Imperial College to write a letter, demanding that Li Bangyan be recalled and Li Gang be reinstated. News came out that tens of thousands of soldiers and civilians in Kaifeng, Tokyo followed Chen Dong to the streets. When Bangyan entered the DPRK, he was scolded for his crimes. Song Qinzong ordered Wu Min to preach and appease, but the crowd did not disperse. Instead, they gathered in the palace to beat drums and shout loudly. Wang Zong, the abbot of the temple, was afraid of change and asked Qin Zong to agree reluctantly. So he sent Geng Nanzhong to tell the masses: "I have got the news and outline." Zhu Gongzhi, the chamberlain, was ordered to summon Li Gang, but he was beaten to death by the crowd and killed dozens of chamberlains for delaying time. Seeing the public anger, Qin Zong ordered Li Gang to be reinstated as You Cheng as Beijing's defense envoy. The crowd gradually dispersed. Chen Dong was a patriotic student in the late Northern Song Dynasty. Chen Dong, whose real name is Shaoyang, is from Danyang, Zhenjiang. Qin Zong was born in the first year of Yuan You in northern Song Zhezong (1086) and died in the second year of Jingkang (1 127) at the age of 40. When Chen Dong was young, his family was poor, but he was famous for his integrity and daring to speak. When Song Huizong was in office, Cai Jing and Wang Nai were pragmatic, and people dared not speak, while Chen Dongze had nothing to hide and often publicly criticized current politics. Later, Chen Dong praised Imperial College London for his profound knowledge. When Qin Zong ascended the throne, he led his classmates to Fu Que to write a letter, saying, "What happened today was Cai Jing's rebellion in the front and Liang Shicheng's plot in the back. Li Yan made enemies in the northwest, Zhu Mian made enemies in the southeast, and Wang Fu and Tong Guan made enemies in Liao and Jin Dynasties, resulting in estrangement. It is right to punish the six thieves and pass them on to thank the world. In the spring of the first year of Jingkang, Chen Dongju accused Liang Shicheng of treason, and Shicheng finally died. In the first year of Jingkang, Li Bangyan, the prime minister, wanted to make peace with the Jin people, and Li Gang fought the main battle, so he ousted him on the pretext of Li Gang's defeat (in fact, it was only a small defeat) and ceded Taiyuan, Zhongshan and Hejian. Chen Dong led the crowd to Liu Bei's door and wrote, "Li Gang is a so-called minister who dares to be the first in the world. "Li Bangyan, Bai Shizhong, Zhang Bangchang, Zhao Ye, Wang Xiaodi, Cai Mao and Li Chang are all so-called traitors. Your Majesty acceded to the throne in a few days, and Chinese and foreign countries congratulated each other, which shows the power of your Majesty Ren Xian. You don't need to know that your majesty can eliminate evil. But when he was appointed as the master, he did not go, but returned to Xiang Bangyan and Xiang Bangchang, both of which were used. Why did your Majesty Ren Xian fail to leave, and he failed to put away evil? I was shocked to hear about my official business today, but I don't know why. The outline begins with ordinary officials and is the only event. Bangyan and others are enemies, fearing that they will succeed. Because of the small disadvantage of using troops, we have to take advantage of the gap and blame it on the procedure. If the husband wins, he loses, and the soldiers are always in the position. How can we use this to shake the ministers in power? I heard secretly that Bunyan and Shizhong tried their best to persuade your majesty that he was lucky. The capital is in chaos. If you don't want to advise your majesty, just follow the trend. The ancestral temple became the ruins of A Qiu, and life was ruined. Lai is clever and not confused, especially from his invitation, Yi Bangyan and others are all jealous. If your majesty listens to his words without using them, it is unknown whether the clan society can survive. Bangyan and others advocated ceding land and building Hebei into a real imperial court without three customs and four towns. If Hebei is abandoned, can the imperial court restore the capital? I wonder if after Bangyan and others cut Taiyuan, Zhongshan and Hejian to the north, can Jin people not lose contact? One advance and one retreat are very light in the outline, and the court is very heavy. Fortunately, your majesty reversed his previous life and resumed his old post, giving a lot to the breeder in order to secure the heart of China and foreign countries. If your majesty doesn't believe me, please ask people from all over the world. There are all of them, and Bunyan and others can also reprimand them. When you use your house, don't comment! There are tens of thousands of military and civilian followers in the book. Seeing the public anger, Qin Zong ordered Li Gang to continue to lead the troops. After the nomads from behind, the court intended to severely punish those who took the lead in writing and those who killed the chamberlain, forbade Fuque to write, and abolished the palace view that could be shared with the people. Jinghe even wants to put all the students in prison. Shi Yang, president of imperial academy, objected, so he reinstated Chen Dong and sent Nie Shan to imperial academy to take care of the students. * * * In order to slander, Chen Dongpai was appointed as an official position and given to the official residence. Chen Dong wrote five letters before and after, urging Cai Jing to be punished and urging him to resign. Song Gaozong acceded to the throne for five days and appointed Li Gang as Prime Minister. On the 5th, I summoned Chen Dong. Chen Dong wrote to Li Gang to recall Huang Qianshan and Wang Boyan. He also asked for personal expedition to save Huidi and Qin Emperor, and severely punished the generals who were not allowed to join the army. Song Gaozong won't accept it. At that time, another scholar, Ouyang Che, also wrote a letter. Huang Qianshan angered the emperor and said that if he was not severely punished immediately, it was inevitable that the Kaifeng student incident would happen again. The emperor then ordered the execution of Chen Dong and Ouyang Che! Under the order, Chen Dong calmly wrote a suicide note and handed it to his entourage: "I am dead, this is what I owe my relatives. Then he told the jailer that he wanted to go to the toilet. The jailer was very reluctant. He smiled and said, "I, Chen Dong, am afraid of death and dare not speak. Did I say I was willing to escape death? The official said: "I also know Gong, and I dare to force it." After Chen Dong took out the crown, he was beheaded in the city with Ouyang Che. Li You, a Siming man, felt his loyalty and privately redeemed Chen Dong's body for burial. Chen Dong and Li Gang don't know each other, only because of the talents in his country and even the sacrifices he made for Li Gang. Knowledge and ignorance are both runny noses. There were two when I was forty. Three years after Chen Dong's death, Emperor Gaozong realized this and elected Chen Dong and Ouyang Che as successors after his death. Chen Dong has no children behind him, but only a paternal relative (maybe an uncle or a cousin). Ouyang Che has a son, who is asked by the county to take care of his family. Later, he sent a guard to offer a sacrifice to Chen Dong's grave and gave him 500 yuan. Emperor Gaozong of Shaoxing for four years, and later he was added to Lang Feng and Secret Pavilion. After that, two officials gave ten hectares of land.

After Jin Taizu Akuta fought against Liao in Lailiu River, he first chose the northern part of Liaodong, which was in contact with Jurchen. Relying on the favorable terrain of holding water in the mountains, the Liao army was lured away from Beijing, Tokyo and other military towns, and moved to Ningjiang, Chuhedian, Hubugang and other places to annihilate the Liao army's effective strength. Then, seize the fighter plane, take Liao, Wu and Beijing as the strategic goals, and carry out the campaign to destroy Liao. The steps before and after the capture of the five capitals were Tokyo, Shangjing, Zhongjing, Xijing and Nanjing, and the strategic planning was thorough and proper. After the occupation of Tokyo, Liaoning Province, the soldiers' grain of fifty-four states was obtained, and the Liaodong Peninsula was connected with the former residence of Nuzhen, which greatly increased the strength of 8 Jin Army. Soon, he went west to Beijing and unplugged the place where Liao Taizu started his business, which made the Liao army frustrated. On the occasion of Jin Jun's successive victories, Liao was expected to die in the Northern Song Dynasty and wanted to seize the opportunity to recapture the sixteen states that had been occupied for a long time. So he made an appointment with Jin to attack Liao, and Jin Yun returned to the sixteen States of Song Dynasty after destroying Liao. However, in Liao War, Song Jun suffered a crushing defeat, but 8 Jin Army won Lien Chan's victory, taking the capital lightly and occupying the vast land of "thousands of miles in territory, mountains and valleys deep enough to ward off evil spirits". Liaozhongjing fell, Xijing and Nanjing lost their barriers, and were successively conquered by 8 Jin Army. After the fall of Zhongjing, Emperor Liao Tianzuo wanted to leave Xixia and was captured by Jin Jun on the way. The Liao Dynasty came to an end, and he spent three years in Jintianhui (1 125). After the demise of the Liao Dynasty, the Song Dynasty humiliated and recovered six states and sixteen counties in Nanjing looted by the Jin Army with thick coins, and its weakness was also known by Jin. After that, Jin began to invade the Song Dynasty and eventually destroyed the Northern Song Dynasty.

Jinlian and Song Dynasty destroyed Jin Taizu and Hong Yan, and Akuta fought in the Lailiu River. After fighting Liao, he first chose the main direction of attack in the northern part of Liaodong, which was in contact with Jurchen. Relying on the favorable terrain of negative mountains and holding water, the Liao army was lured away from Beijing, Tokyo and other military towns, and moved to Ningjiang, Chuhedian, Ansang and other places to annihilate the effective forces of the Liao army. Then, seize the fighter plane, take Liao, Wu and Beijing as the strategic goals, and carry out the campaign to destroy Liao. The steps before and after the capture of the five capitals were Tokyo, Shangjing, Zhongjing, Xijing and Nanjing, and the strategic planning was thorough and proper. After the occupation of Tokyo, Liaoning Province, the soldiers' grain of fifty-four states was obtained, and the Liaodong Peninsula was connected with the former residence of Nuzhen, which greatly increased the strength of 8 Jin Army. Soon, he went west to Beijing and unplugged the place where Liao Taizu started his business, which made the Liao army frustrated. On the occasion of Jin Jun's successive victories, Liao was expected to die in the Northern Song Dynasty and wanted to seize the opportunity to recapture the sixteen states that had been occupied for a long time. So he made an appointment with Jin to attack Liao, and Jin Yun returned to the sixteen States of Song Dynasty after destroying Liao. However, in Liao War, Song Jun suffered a crushing defeat, but 8 Jin Army won Lien Chan's victory, taking the capital lightly and occupying the vast land of "thousands of miles in territory, mountains and valleys deep enough to ward off evil spirits". Liaozhongjing fell, Xijing and Nanjing lost their barriers, and were successively conquered by 8 Jin Army. After the fall of Zhongjing, Emperor Liao Tianzuo wanted to leave Xixia and was captured by Jin Jun on the way. The Liao Dynasty came to an end, and he spent three years in Jintianhui (1 125). After the demise of the Liao Dynasty, the Song Dynasty humiliated and recovered six states and sixteen counties in Nanjing looted by the Jin Army with thick coins, and its weakness was also known by Jin. After that, Jin began to invade the Song Dynasty and eventually destroyed the Northern Song Dynasty. The mistake of uniting Jin to destroy Liao in the Northern Song Dynasty was a big mistake. Originally, the Song Dynasty had to rely on its own efforts to recover the lost land of Yanyun. However, Songshi didn't want to work hard, which led to the decline of North Korea and the weakness of the army. Therefore, he dreamed of "controlling foreign countries with foreign countries". At that time, compared with Jin, Liao declined and Jin flourished, while Song Junchen was short-sighted and even joined hands with Jin to destroy Liao. As a result, in the war against Liao, Song exposed his political decadence and military incompetence, and "Song obeyed his will" in many negotiations with Jin, which greatly encouraged the emerging Jin's ambition to win the Central Plains.
