Before leaving for the Liao State, Liu Chen and Lu Dazhong consulted the documents and drawings of the Song and Liao sides on the land boundary and found that the Song side did not invade the Liao territory, so they reported the situation to Zhao Xu, the Song Shenzong, and said that they would fight on the basis of reason.

Unexpectedly, Song Shenzong Zhao Ji didn't want to fall out with the Great Liao State because of the land of projectiles, so he said to Liu Chen: "After the Liao people are exhausted, they will take extreme actions, so you can just promise to give them some land." ”

What is extremist action? It was worried that the Liao State would launch a war of aggression against the Song Dynasty, and the Song Dynasty was in full swing with the Western Xia at that time, and he really didn't want to provoke the Liao State again.

Of course, what Song Shenzong didn't know was that Yelu Hongji, the emperor of Liao at the time, also had doubts about whether to use troops against the Song Dynasty. Although the Song and Xia battles are a good opportunity to win chestnuts in the Great Liao, how can they be suddenly resolved when the soldiers are exchanged? In the end, the Song Dynasty was a big country, if the wall was strong and clear, dragging the Liao State into the quagmire of war, and the land occupied could not scrape out the wealth, but it cut off the annual annual currency income, it was really a bit more than worth the loss!

For this reason, Yelu Hongji specifically asked his trusted minister Yao Jingxing.

Yao Jingxing's ancestor was originally a general of the Later Zhou Dynasty, and he was sent to the Great Liao during the reign of Yelujing of Liao Muzong, but was detained in the Liao State and became a slave. Yao Jingxing was born in the Liao Shengzong Yelu Longxu Dynasty, and in the Liao Xingzong Yelu Zong Zhen Dynasty to get the Jinshi, because of his erudition, he served as Yelu Hongji's teacher, and later served as Lin Ya (Lin Ya in the Khitan official system, that is, the Hanlin Bachelor of the Song Dynasty), the privy deputy envoy, after Yelu Hongji ascended the throne, Yao Jingxing was promoted to participate in political affairs, and soon he was promoted to the prime minister of Beifu, and later resigned due to affairs.

When Yelu Chongyuan's father and son betrayed Yelu Hongji, Yao Jingxing was on his way home, and after hearing the military situation of Yelu Chongyuan's father and son's rebellion, he immediately rushed to Luanhe Palace Qinwang, and by the time he arrived at Luanhe Palace, the rebellion had been quelled. Yelu Hongji felt that Yao Jingxing was loyal, so he appointed him as the envoy of the Wuding Army, and after Yelu Yixin squeezed Yelu Ren out of the court, Yao Jingxing returned to the court to replace Yelu Yixin (at this time, Yelu Yixin had been promoted by Yelu Hongji to the privy envoy of the Northern Court) as the privy envoy of the Southern Court.

Yao Jingxing was deeply trusted by Yelu Hongji, and whenever he encountered something that he was not sure about, he asked Yao Jingxing more. Yao Jingxing was opposed to Yelu Hongji's dispatch of troops to the Song Dynasty: "Since Emperor Shengzong (Yelu Zhenxu) signed the alliance with the Song, the Song has been paying tribute to the Liao every year for nearly 70 years, and if the Song is used, I am afraid that the treaty signed between the first emperor (Yelu Longxu) and the Song will be broken." ”

Yelu Hongji listened to Yao Jingxing's words and felt that it made sense, subverting the political achievements of his ancestors, that is, not to show his descendants, although this face is not valuable, he still has to ask for it when he should want it. Therefore, Yelu Hongji dismissed the idea of using troops in the Song Dynasty, but put forward a request for land from the Song Dynasty.

The Liao State did not send troops, but only used important land to contain the Song Dynasty's attack on the Western Xia, leaving the Western Xia as the sick block of the Song Dynasty, which was Yelu Hongji's strategic deployment.

However, Song Shenzong didn't know that the emperor of Liao was also afraid of the wolf in his heart, and in the face of the threat of the clay-footed giant, his waist and spine became the girl's waist cotton bag, which was so soft that it was lovely.

Fortunately, although Song Shenzong wanted to cede the land to calm the people, the bones of the envoys of Liao, Liu Chen and Lu Dazhong, were very hard. After arriving in Liao, the two of them did not follow the will of Song Shenzong to bend the knee to the emperor of Liao, but argued on the basis of facts.

The Song envoy was tough, and Yelu Hongji had no idea. In the end, the Song and Liao sides jointly sent officials to the border to discuss the issue of demarcation of the territory.

Xiao Su, the representative of the Liao side, waved his hand, and naturally the lion opened his mouth widely, and he was angry and swallowed 100,000 heavenly soldiers, and the more land he rowed, the better; And Liu Chen and Lu Dazhong of the Song side were justified and dismissed one by one. The two sides were at loggerheads, so they had no choice but to settle down.

In September of that year, the persevering Yelu Hongji sent Xiao Xi to the Song Dynasty again to discuss land boundary matters.

In the face of the important land of Liao, Zhao Ji of Song Shenzong still made up his mind to treat others with condescension, so he found Liu Chen, Lu Dazhong and the relevant ruling ministers to discuss, and was ready to agree to give Liao some more land.

Lu Dazhong was furious: "They only sent one envoy to give them five hundred li of land, if they send a prince to ask for the land of the ten counties in Guannan, will they also give it to them?" ”

The ten counties of Guannan are talking about the old things of Yelu Hongji's father, Liaoxingzong Yelu Zongzhen - Yelu Zongzhen also took advantage of the war between the Song Dynasty and the Western Xia Dynasty to ask the Song Dynasty for the ten counties of Guannan. The Song Dynasty took Fu Bi as the negotiating envoy, and the ten counties in Guannan naturally refused to give it, but in order to avoid fighting on the two fronts of the Western Xia of the Liao State, the Song Dynasty could only stop the attack on the Western Xia, and had to hemorrhage profusely - in the future, the annual coin of the Liao State would be increased by 200,000 yuan - Liao Xingzong was not only gracious to the Western Xia, but also received the special treatment of the Song Dynasty, which can be described as killing two birds with one stone.

Today, Yelu Hongji also came to ask for land, and it turned out that he was just picking up his father's remnants.

Liu Chen, like Lu Dazhong, also insisted on not giving Liao land.

At this time, Wang Anshi, who was relied on by Zhao Ji as the minister of the society, had been demoted from the court because the new law was difficult to implement and offended many people. Song Shenzong, who had lost his right-hand man, was not angry in his heart, and when he saw that Liu Chen and Lu Dazhong violated his will everywhere, he couldn't help but lose his temper, so he pushed Liu Chen and Lu Dazhong's official positions to the end, and then ignored the important land in Hedong.

He ignored it, and couldn't stop Yelu Hongji from thinking about it. In March 1075, Yelu Hongji again sent Xiao Xi as an envoy to the Song Dynasty to urge the demarcation of the border, and the two sides were naturally in dispute. Song Shenzong Zhao Ji had no choice but to send Shen Kuo as an envoy to Liao, in order to solve the problem of the boundary between the two sides.

Shen Kuo is the almighty god who wrote "Mengxi Writings", and he is a high-grade character with the Eastern Evil Huang Yaoshi in terms of talent, and even Huang Yaoshi is slightly inferior - because Shen Kuo was also a famous geographical expert at that time. Before leaving, he found out the documents and drawings for the demarcation of the Song and Liao sides in recent years from the Privy Council, and said to Xiao Xi after straightening it out: "The boundary between the two sides was originally on the first line of the ancient Great Wall, but now the disputed location is more than 30 miles within the ancient Great Wall, what else is there to dispute?" This time, Xiao Xi looked at the documents and drawings and was speechless.

After the envoys of the Song Dynasty arrived in Liao, Shen Kuo took out the documents and drawings on the demarcation of the border between the two sides in recent years and explained them one by one. Under the old shame and anger, Yang Zun tried to see the dagger, showing the hideous face of the foreign strong and the middle cadre: "You can't bear to give up a few miles of land, do you want to lightly cut off the friendly relations between the two countries?" ”

Shen Kuo-for-tat: "If you are famous, you are reasonable, and if you are unknown, you will be defeated." Now that your Liao State has discarded the great faith and righteousness of the emperor of the previous dynasty and provoked trouble at will, is this harmful to our country? ”

The two sides quarreled again, and after six rounds of negotiations, the Liao side was still unable to make Shen Kuo submit, so he gave up the original boundary he wanted to demarcate and proposed a new boundary, and Shen Kuo promised to return to China and make a decision again.

On the way back to China, Shen Kuo painted the mountains, rivers and other terrain along the Liao Kingdom into the "Khitan Map" and presented it to Zhao Ji of the Song Dynasty.

After the Liao State was weakened by Shen Kuo, the new land boundary proposed was less than the original land demand, and Song Shenzong agreed to the Liao side's request and sent people to demarcate the land boundary. However, when the boundaries were demarcated, the Liaoning deputies again demanded more demarcation, and the true nature of the scoundrels was exposed, and the two sides once again quarreled.

So, Song Shenzong Zhao Ji asked Wang Anshi's opinion. Wang Anshi offended the powerful people in the court because of the change of law, and because the new law was difficult to implement smoothly, he was removed from the post of prime minister in 1074 AD. Wang Anshi said to Song Shenzong Zhao Ji: "If you want to get it, you must give the other party some benefits in advance. After speaking, with a stroke of the pen, he drew a sketch according to the original boundary proposed by the Liao side and handed it to Zhao Ji of Song Shenzong.

Song Shenzong Zhao Ji saw that Wang Anshi coincided with his own intentions, and his heart was happy. As a result, this map of the land boundary drawn by Wang Anshi and approved by Emperor Shenzong of the Song Dynasty was handed over to the representatives of the Liao State, and all the land originally claimed by the Liao side was ceded to the Liao State, totaling more than 700 li.

Among the ministers of the Song Dynasty present, some could only shake their heads and sigh: "From now on, Song has no danger to Liao!" ”

Subsequently, when Song Liao specifically demarcated the border line, the Liao State ate the marrow and knew the taste, and added some additional land to add to it. All right! As a result, the Song-Liao border area extended southward to the Yanmen Pass.

The dispute between the Liao and Song Hedong boundaries lasted three years, ending with the Liao State gaining more land, and the Song Dynasty also had to reorganize its troops to the north because of the dispute over the Hedong boundary provoked by the Liao State, so it could no longer take large-scale military action against the Western Xia - the Song general Wang Shao at that time had already appeased and conquered many Tubo tribes in the Xihe region, and built the Xihe Road in Xizhou, leading all the land in the six prefectures of Xixi, He, Tao, Min, Die, and Tang, forming an encirclement of the Western Xia - such a good strategic situation was destroyed because of the extraneous branches of the Liao State, It's a pity.

Ximen Qing read the history here, and he sighed for a long time, and today, he wants to use the shame of losing the land in Hedong in the past to achieve his strategy.

There are many reasons for the ministers of the Liao State to oppose the Yanyun Concession, the most important one is that the territory of the Sixteen Prefectures of Yanyun is far beyond the Daimyo Mansion, and after the two countries established the concession, the Song Dynasty gained more land and the Liao State got less land, which was too cost-effective, so it can be seen that the Southern Dynasty was not sincere.

But now Cheng Wanli's proposal to increase land is to put the ten counties of Guannan that Liaoxingzong Yelu Zong really claimed as a bargaining chip on the negotiating table - the ten counties of Guannan that Liaoxingzong Yeluzong Zhenjun and his ministers did not get their hands on back then, this time they were made into a concession of Liao by Yelu Yanxi's monarchs! This kind of feat that surpasses the ancestors, the effect of political propaganda is immeasurable!

The next day, the Liao lord set up a dynasty, and as soon as the proposal to exchange the Yanyun Concession of the Liao State for the Daimyo Concession of the Chinese Federation and the Guannan Concession came out, there was a sudden silence in the court! This is exactly what it is:

Row out the nets to catch the tigers, and sprinkle incense bait to catch the golden turtles. But I don't know what will happen next, and listen to the next breakdown.
