1259, Kublai Khan led the Eastern Route Army to attack Ezhou in the Southern Song Dynasty. Jia Sidao was very scared. He sent people to Mongolia to make peace with Kublai Khan and proposed to submit to Mongolia, with the Yangtze River as the boundary, and pay Mongolia 202,000 pieces of silver and 200,000 pieces of silk every year. Kublai Khan knew that Mongo was dead at this time, and he wanted to go back to the north to fight for Khan's position. He was very happy, so he agreed to Jia Sidao's request and led the troops back to the north. & gt& gt In April, the first year of reunification (1260), Kublai Khan sent Hao Jing to the Song Dynasty, demanding that the Southern Song Dynasty fulfill the proposal of drawing a river as the boundary and contributing 202,000 silver wires. After a year, not only did the Southern Song Dynasty not send silver silk, but even Du Jing's news was gone. Kublai Khan was furious. In July of the second year of reunification (126 1), I ordered the transfer of troops to cut the Song Dynasty, and wrote: "After I acceded to the throne, I deeply thought that I would use troops, so I sent an envoy to Zhu for peace years ago. Song people didn't care about the distant future, but waited for my little gap. They betrayed the border, plundered the east and the west, and there was no peace. When I returned to the palace this spring, my ministers invited me to recruit soldiers for Nan. I cherish the lives of both countries and wait for the messenger to return. I have a heart of peace, and those who stay but don't arrive will be righteous for half a year. Politeness in communication is abrupt, and intrusion is violent. He pretends to be a country of clothes, manners and music, right? The difference between right and wrong is obvious. Leave a legacy to. Young people and others should set foot soldiers, sharpen spears, bow and arrow, date generals, be arrogant in autumn, be tall and big, and move forward separately from land and water, thinking that they are guilty. It still depends on the spirit of the ancestral temple, which is glorious. Your Majesty and others should declare our hearts and tell the soldiers clearly that they should encourage themselves and not save our lives. " Kublai Khan exposed the crime of arbitrarily detaining messengers in the Southern Song Dynasty in his letters, saying that he would never stop until the Southern Song Dynasty was destroyed. In a rage, Kublai Khan remembered what the Mongolian three armies had said when they attacked Song, and decided not to attack Song on a large scale for the time being. & gt& gt Kublai Khan was indeed wise to stop his massive attack on the Song Dynasty. Because the situation in Mongolia at this time is not as good as when Mongolia attacked the Song Dynasty, only as bad. At that time, after Kublai Khan ascended the throne, the regime had not been fully consolidated, and Ali's struggle for Khan's status was fierce, followed by the Hou Li rebellion in the Han Dynasty. Internal affairs rectification has just begun, and economic recovery and development have not yet fully entered the track. It can be said that the situation at that time was civil strife. After some thinking, Kublai Khan decided to put up with the unreasonable detention of the emissary in the Song Dynasty for the time being, and put his main energy into pacifying civil strife and rectifying internal affairs. & gt& gt Under the situation that Kublai Khan put down civil strife, stabilized order, developed economy and prospered national strength, the Southern Song Dynasty not only failed to seize the opportunity of revitalization, but became more corrupt. Li Zong was a very fatuous emperor in the Southern Song Dynasty. After he succeeded to the throne, the traitor Shi staged a coup in Ningzong's coffin. He knew that he was put on the throne to specialize in state affairs. So, he gave all the power to Shi and became a puppet himself. It was not until six years later that Shi died of illness that he "led the government". After Li Zong's "pro-government", he once appointed Dong Huai as the prime minister, but he was quickly excluded. & gt& gt In the year of the Qing Dynasty (1259), Daquan Ding was suspended for blocking the news of Mongolian attack on the Song Dynasty, and Jia Sidao began to control the regime of the Southern Song Dynasty. & gt& gt Jia Sidao's younger sister was Li Zong's favorite imperial concubine in his early years. With the help of Jia Guifei, when she was stopped in Daquan Ding, she was promoted to the right prime minister, led the troops to help Ezhou, and made an alliance with Kublai Khan privately. It is even more arrogant to hide the truth afterwards and lie about victory. In his later years, regardless of state affairs, Jia Sidao decided to establish Zhao as Emperor Du Zong based on his personal likes and dislikes. Song Duzong is even more fatuous. Because Jia Sidao has the decision-making power, he will answer every pilgrimage and call Jia Sidao "teacher" instead of calling him by his first name. Guan Bai called him "Duke of Zhou", and Song Duzong allowed Jia Sidao to visit the DPRK once every three days, once every six days and once every ten days. Although Jia Sidao goes to court every day, he has to make a decision, and officials at all levels have to go to his house with documents to ask for instructions and sign. Even when I get to his house, I'm too lazy to do it myself. I didn't do anything. I gave them to Liao Ying, a guest of the museum, and Weng Conglong, an official of the guild hall. Jia Sidao handles political affairs, and everything is done according to his own self-interest. Officials are vying for the position of beauty. The picture shows the division, supervisor and county health. Their contributions are numerous, and they are greedy for a while. "Who is good at flattery, who can get high officials. Anyone who can't flatter and be upright will be excluded and persecuted. Liu Zheng, the envoy of Tongchuan government, and other military commanders were driven out of Nanzhu and surrendered to Mongolia because of Jia Sidao's jealousy. Wen Tianxiang, Li Fu and other upright scholar-officials were also rejected and hit. In the imperial court, only * * people in Jia Sidao. & gt& gt Jia Sidao not only made the court corrupt, but also made his personal life quite decadent. The decadent life of Jia Sidao and others is entirely based on the suffering of the people. In order to satisfy his luxurious life and solve the government's fiscal deficit, he introduced the so-called "law of commons", which nominally stipulated that every household's land exceeded a certain amount and was sold to the government as "commons", and the government paid the land price accordingly. In fact, it is a low-cost extortion, and the land price paid is used as the "official notice" and "official account" of the paper money "Huizi" technology. In this case, it is just like waste paper. Make people's wives and children separate, and the family is ruined. & gt& gt Jia Sidao also arbitrarily assessed and extorted money. In addition to increasing the "two taxes", they also used various excuses to extort money. Even if the lawsuit is unsuccessful, you have to pay a fine. If the lawsuit is successful, you have to pay happy money and suck up nothing. Jia Sidao made the decadent Song society more corrupt. & gt& gt After Kublai Khan defeated Ali Buge, put down Li's rebellion and stabilized the internal situation, he heard that Jia Sidao was in power in the Southern Song Dynasty and complained bitterly that the time was ripe to destroy the Song Dynasty, so he lost no time in launching a war to destroy the Song Dynasty. & gt& gt In March of the first year of reunification (1260), Kublai Khan sat in a big sweat position in Kaiping. At this time, Kublai Khan was willing to make peace with the Song Dynasty in order to compete with the Alibaba brothers for the position of Khan. So, according to the usual practice, he sent a mission, with a bachelor's degree in Hanlin as the ambassador, Dr. He Yuan from Hanlin, and Dr. Wei Liu from does, to report the news of Kublai Khan's accession to the throne in the Southern Song Dynasty, demanding that the Southern Song Dynasty fulfill the peace treaty signed with Jia Sidao. Who knew that Jia Sidao did it behind the court's back? Afterwards, I concealed the secret and the truth, fabricated the lie of Ezhou's victory, and said that the troops I sent were all victorious. " Hubei began to solve, Jianghan eliminated. It is a kind of rest without borders for the clan society to recover from danger. "See Jia You transformation, then promoted Jia Sidao to satrap, praise. & gt& gt When Hao Jing established the Song Dynasty, Jia Sidao was asking Liao and others to compile "An Analysis of Hua Fu" to praise his great contribution in solving the problem of Ezhou encirclement. He heard that Hao Jing and others were coming, fearing that he would secretly lie to Kublai Khan about the military situation, so he ordered Huaidong Manufacturing Company to detain Hao Jing and others in the brave military camp in Zhou Zhen (now Yizheng, Jiangsu), and the Mongolian ambassador immediately became a prisoner under the order. & gt& gt Hao Jing was detained for no reason and was at a loss. He wrote to the Song Emperor, "I am willing to attach the meaning of Lu Lian to solve problems; I don't know that frugal people and soldiers are wrong. "That is willing to contribute to the reconciliation between Mongolia and the Southern Song Dynasty. Jia Sidao ignored it. Hao Jing thought that the Southern Song Emperor was unwilling to make peace and detained him. He wrote to the emperor several times and said, "I don't know why your dynasty accepted his envoy and detained him in the border county. He was shrouded in power and refused to advance or retreat. In a room, he turned and turned, and he didn't see the sun for many years. "I hope that the Emperor of the Song Dynasty will respond to Kublai Khan's good wishes and save the people of the North and South from the scourge of killing." Hao Jing's Song Shu was detained by Jia Sidao. When Hao Jing saw no news, he asked to see Emperor Song in person, but he didn't reply.
