Wanyan Yong's father, Wanyan Zongyao (first name Zongfu), is the third son of Wanyan Aguta. Wanyan Zongyao is more intelligent, and when Wanyan Agu beats the sons to lead the troops to the battle, Wanyan Zongyao often strategizes in the battle. He advocated the use of the Han system against the Han people, which was somewhat different from the killing policy pursued by Wanyan Zonghan and others.

In the thirteenth year of Tianhui (1135), Wanyan Zongyao died, when Wanyan Yong was only 12 years old. His mother, Li Hongyuan, was born in the Bohai clan of Liaoyang and was smart and capable. When he was young, Kim Sejong was mainly raised by his mother. According to the custom of Kim, after the death of her husband, the wife should marry someone from the clan. Li was unwilling to accept this backward custom, so he became a nun in Liaoyang.

Wan Yanyong looks very burly, has a quiet and wise personality, and is good at riding and shooting. When he was young, every time he went hunting, many old people followed him to see it, praising his riding and archery skills, "the Chinese people pushed it first". He was a generous man, and often accompanied his uncles to fight everywhere, and the soldiers respected him very much. During the reign of Emperor Jin Xizong, Wanyan Yong was awarded the Guanglu doctor by the son of the clan, and he was crowned the king of Ge and the secretary of the military department.

In the later period of Jin Xizong's reign, he often drank heavily and killed his relatives and ministers, but it was better for Wan Yanyong. When Yan Zongyao conquered the Song Dynasty, he got a white jade belt used by the emperor of the Song Dynasty as a family heirloom. Wan Yanyong cherishes it very much. Wan Yan Yong's wife, Wu Linda, said to him: "This jade belt is not what the palace should have, but should be dedicated to the Son of Heaven." Wan Yan Yong felt that her words were reasonable, so he dedicated the white jade belt to Wan Yan Yong, won the favor of Wan Yan Yong's Mourning Queen, and also won the trust of Xizong.

At the beginning of the reign of King Wanyan Liang of Hailing, Wanyan Yong sentenced Huining (now south of Acheng County, Heilongjiang) to pasture, and soon, he sentenced the main matter to Tokyo (now Liaoyang, Liaoning) to stay, and later changed to Yanjing (now Beijing) to stay behind, Jinan Mansion Yin, Xijing (now Datong, Shanxi) to stay and other positions. Wanyan Yongneng is capable of literature and martial arts, and has a high prestige among the Jurchen nobles, and King Hailing is very uneasy about him, and often transfers his official position. After the Wulin Jing clan persuaded Yan Yongduo to offer treasures to King Hailing, in order to dispel his suspicions and avoid being punished. Wan Yan Yongzhao took his wife's words, and gave treasures such as the Liao Gu Rhinoceros Pei Ma and the Tuhu Liangyu Tea Vessel to Wan Yan Liang. Wan Yan Liang thought that Wan Yan Yong was afraid of him, and he was very deferential to him, and his suspicion was slightly relieved.

Later, Wan Yan Yong was appointed to stay in Tokyo, Wan Yan Liang let the Wu Lin Da clan enter Beijing as a hostage, knowing that Wan Yan Liang's lustful Wu Lin Da clan had to enter Beijing, and committed suicide when he was 70 miles away from the central capital. Before his death, the Wulinda clan left a desperate suicide note to Wan Yanyong, which is known as the "Book of the Ancestors of the Last World". affectionately begged her husband not to grieve because of her death and "be a child", to "lie down and taste the courage", and to "cultivate morality, discipline, recruit heroes, and please the people", and wait for the opportunity to "seize the throne and calm the world in anger." ”

Wan Yan Yong endured humiliation and humiliation for his beloved wife who died for him, cut his love to hide his grief, and did not show his resentment towards Wan Yan Liang. did not go to the place where the Wulinda clan died, and personally handled the aftermath, but just asked the subordinates to bury the matter on the spot, and hid the deep hatred of taking his wife to death in his heart, causing Wan Yan Liang to let Wan Yan Yong go, but he still sent his henchman Gao Cunfu to stay in Tokyo to monitor him.

In the sixth year of Zhenglong (1161), Wanyan Liang mobilized a large number of troops, material and financial resources to invade the Song Dynasty in the south, so that "the people were trapped, food and clothing were not given", "the people were unbearable, and thieves swarmed". The Khitans were unwilling to serve as soldiers, killed the officials of the Jin Dynasty, seized 3,000 pairs of armor, and staged an uprising. Wan Yanliang's reign was even more unstable.

Wanyan Yong's uncle Li Shi persuaded him to accumulate strength and seize the supreme ruling power of the Jin Dynasty, and they also actively built military armor. Gao Cunfu knew about this matter, and secretly sent someone to tell Wan Yanliang; At the same time, he also conspired with the official Li Yanlong to kill Wan Yanyong. Fortunately, Gao Cunfu's family told Wan Yanyong the secret. Wan Yan Liang learned that he sent Mou Lianghu to kill the clan brothers. When Wan Yanyong heard this, he was very frightened, and Li Shi advised him to take the throne as soon as possible.

After some deliberation, it was decided to summon the Tokyo officials to a meeting at the Sei'an Temple, where his mother was a monk, under the pretext of discussing the matter of preparing for the "thief". Gao Cunfu didn't dare to come, Wan Yanyong sent people to summon him many times, and he came. Wan Yanyong arrested Gao Cunfu and Li Yanlong on the spot. On the third day of October, Wanyan Fushou and others led 20,000 Jin troops from Shandong, and Wanyan Mouyan led more than 5,000 troops from Chang'an (now northeast of Shenyang, Liaoning).

On October 7, various armies entered the city and jointly killed Gao Cunfu and others. The next day, the officers and their subordinates came to Wanyan Yong's mansion to ask for a meeting. Wan Yanyong had just walked out, and all the officers and subordinates shouted long live in the court. Wan Yan Yong pushed and gave in, and the generals and officials repeatedly persuaded him to advance. So, Wan Yan Yong personally went to the Taimiao to pay tribute to his ancestors, and then came to the Xuanzheng Hall to ascend the throne of the emperor, which was for Jin Shizong. After Yan Yong ascended the throne, he changed the Yuan Dading and issued an edict to abolish Wan Yan Liang. Thus began his 29-year reign.

At this time, Wan Yan Liang, who was on the north bank of the Yangtze River, had already learned that Wan Yan Yong had an army in Liaoyang and was called the emperor, and he also wanted to stop the war against the Song Dynasty and lead his troops north to encircle and suppress the Dading regime. However, Wan Yanliang mistakenly listened to the advice of Li Tong, a close confidant around him, that is, after crossing the Yangtze River first, until Lin'an (now Hangzhou) in Kyoto of the Southern Song Dynasty, destroyed the Southern Song Dynasty, and then returned to attack Jin Shizong, and won both victories. In the end, it turned out that Wan Yanliang completely miscalculated. Wan Yanliang led his troops to the north bank of the Yangtze River, that is, he selected the riverside town of Quarry Town on the border of Anhui Province to launch the war of attacking the Song River and crossing the river, but the result was a quick failure with heavy casualties.

At this time, the Jin soldiers who conquered the Song Dynasty in the south also learned that Wan Yan Yong had established the Dading regime in Liaoyang and raised the banner to rebel against Wan Yan Liang, the king of Hailing, so the Jin soldiers on the front line felt that there was a way out for their lives. The soldiers began to plot to be led by Yelu Yuanyi, the Khitan commander, and then led by his son Yelu Wangxiang, to launch a mutiny of the Jin army on the front line. In the middle of the night on November 27, the mutinous Jin soldiers rushed into the Guishan Temple in Guazhoudu, the big tent of the Chinese army ——— Wanyanliang, and shot Wanyanliang, the king of Hailing, to death. The regime of King Hailing fell immediately. The army of the Jin Dynasty, which conquered the Song Dynasty in the south, was also defeated and retreated from the battlefield like a tide and fled to the north, so that the war against the Song launched by Wanyan Liang ended in complete defeat.

On December 19, Jin Shizong led his troops all the way to Yanjing Zhongdu, seized the central power of Jin, and began Jin Shizong's imperial career of completing Yan Yong's generation. Wan Yan Yong's ability to successfully ascend to the emperor's throne is not accidental. As far as he himself is concerned, since he became an official, he has been "in charge of other counties for a long time, and he knows the gains and losses of the rule of officials because of the chaos and troubles", and he has rich practical experience in governance. Therefore, whether among the Jurchen nobles or the Bohai clan, he was very prestigious. From the perspective of Emperor Hailing, the supreme ruler of the Jin Dynasty at that time, he was far away from the ruling center of the Jin Dynasty because he commanded the war of the Southern Expedition to the Song Dynasty, which brought favorable conditions for Wan Yanyong's accession to the throne. What's more, Hailing's war against the Song Dynasty was extremely unpopular, and the Jin Dynasty opposed this war from top to bottom. This provides conditions for the accession of Yan Yong.

Although Wan Yanyong successfully ascended the throne, the political situation of the Jin Dynasty after his accession to the throne was troubled internally and externally, with the Jin Dynasty nobles vying for power and profit, and the uprisings of the people of all ethnic groups outside. Therefore, the first task facing Yan Yong after his ascension to the throne is how to stabilize the political situation.

Wan Yan Yong opposed Wan Yan Kang and Wan Yan Liang's indiscriminate killing of the opposition of the clan nobles, and as soon as he ascended the throne, he expressed his defense of the clan nobles and adopted a policy of tolerance and generosity towards the high-ranking officials under Hailing. After the edict counted dozens of sins such as Yan Liang killing the Empress Dowager, Jin Taizong, Zong Han and Zong Bi, destroying Shangjing, etc., and demoted him to King Yang; Then Wan Yan got rid of the title of King of Dongdu, restored his reputation, added the name Xizong, and was buried in Siling; He also repaired the palace of Huining Mansion that was destroyed by Hailing, and restored the title of Shangjing. He also issued several edicts to restore the status of those who had innocently killed the families of ministers and those who had been reduced to slavery;

For the bones of those ministers, they sent people to visit everywhere, and when they got them, they were collected and buried by the government; Those officials who were cut or demoted by Hailing without reason were given corrections and hired only according to their qualifications. These measures all played a role in appeasing and entrapping the nobles of the Jurchen clan. For those who had been against him and had talents. Wan Yan Yong is not afraid of previous grievances, and still reuses.

When Yan Liang finished Yan Liang's Shangshu Zuo Cheng, the right leading army governor Shi Lie Zhining, was very talented, and before Yan Yong ascended the throne, he and the general Bai Yanjing and others were ready to attack Yan Yong. After Yan Yong ascended the throne, he sent envoys to win them over, but Su Shi Lie Zhining not only refused to submit, but also killed nine envoys successively. After Wan Yan Yong conquered Fushi Lie Zhining by force, not only did he not blame him, but also entrusted him with a heavy responsibility.

Zhang Xuansu, who was the transfer envoy of Tokyo Road at the time of Wan Yanyong, was also very talented. He had sued Wan Yan Yong in front of Wan Yan Liang. After Yan Yong's accession to the throne, Zhang Xuansu went to see him, and Sejong "didn't ask about everything" about the past, but appointed him as the head of the household. Zhang Hao, who was the prime minister and stayed in Nanjing, was an old minister of the Jin Dynasty. Wanyan Yong worshiped him as the Taishi, Shang Shuling, named the king of Nanyang County, let him enter the court without worshipping, and also set up a special seat for him in the east of the main hall, which respected him very much. Wanyan Yong's policy of appointing people without jealousy of previous grievances caused the Jurchen nobles and officials under Hailing to come to defect one after another, and the supreme ruling group was soon stabilized.

The great uprising of the herdsmen of all ethnic groups, especially the herdsmen's uprising led by the Khitan people to move to the nest, seriously threatened the rule of the Jin Dynasty. Therefore, after he ascended the throne, he immediately used both appeasement and suppression to deal with the rebels. He first sent Zha Ba to recruit the rebel army, but Zha Ba saw that Wo was prosperous, and instead joined the rebel army. At the end of the sixth year of Zhenglong (1611), he was called emperor.

Wan Yan Yong hurriedly sent troops to suppress it, and the soldiers sent were all defeated by the Wo Hu rebel army. In the first month of the seventh year of Zhenglong (1612), Wanyan Yong sent the right deputy marshal Wanyan Mouyan and other commanders to suppress it, and promised generous conditions to those who surrendered, and also carried out rebellion activities in the uprising. In this way, one person is isolated. In the autumn of that year, Wo Hu was betrayed, captured and killed, and the uprising failed. A part of the rebel army defected to the Southern Song Dynasty. Jin Shizong's suppression of the leader of the uprising was very cruel, not only beheading the nest in the city, but also cutting off his hands and feet and hanging them in various capitals. Then he sent people to appease the Xi and Khitan tribes. In order to prevent the Khitan people from resisting, Wan Yanyong incorporated the Khitan people who participated in the uprising into the Jurchen Meng'an Moke tribes, so that they could be mixed and easy to rule. In this way, the territory of the Jin Dynasty temporarily achieved a relatively stable situation.

Wan Yanyong focused his main energies on the rectification of internal affairs and social and economic development. He made some additions and detriments to the system of the previous generation, and the prime minister added two Pingzhang political affairs, which further strengthened the imperial rule.

In terms of ruling policy, Wan Yanyong implemented a policy of resting with the people. In the second year of Dading (1162), he sent all the infantry troops from the Central Plains to participate in the southern expedition home; At the same time, officials were sent to Shandong, where the Han uprisings were intensive, to appease the peasants who had taken risks due to the harsh military service and labor during the Zhenglong period, and as long as they returned to the peasants in time, they would all be pardoned. In the third year of Dading, for the Jurchen households who moved to the Central Plains, all those whose fathers, brothers and children were in the army, they were also sent to return home to farm. In the sixth year of Dading, as soon as the war against the Song Dynasty ended, only 60,000 soldiers were left, and the rest of the soldiers were also released.

Wan Yanyong also partially adjusted class relations. After the Jin Dynasty destroyed the Liao, in order to meet the needs of the Jurchen slavery, the Liao Dynasty turned the Liao Dynasty's second-tax households with their own economy and monasteries into slaves. In the second year of Dading (1162), Wan Yanyong not only exempted more than 600 people from the two tax households who had indeed been exempted as good citizens, but also issued an edict that all slave expulsors and palace prisoners who returned from the rebel army in the relocation of the nest were also exempted. In the third year of Dading (1163), he ordered that those whose wives were sold due to war and famine in Zhongdu and other places should be redeemed by the government. In the twenty-second year of Dading (1182), the Jin Dynasty stipulated: Anyone who is limited to the release of good slaves, and marries a good man within the limit, the children born are good people. Similar to the official purchase of good citizens and the partial emancipation of slaves, it played a certain positive role in easing class contradictions. Economically, Wan Yanyong actively resumed and developed agricultural production, lightened the burden on peasants, recruited exiles, and reclaimed land. In order to restore and develop the social economy, he was thrifty, not luxurious, strict with himself, and disciplined the princes and ministers.

When the kings asked the court for additional rewards, Wan Yan Yong said to them: "Why are you people so greedy, don't you know that the property in the state treasury is the property of the people, and I am just keeping it for the people, how dare you spend it in vain?" It is precisely because Jin Shizong was able to correctly understand the relationship between the ruler and the common people, and did not use the treasury assets casually, that during his reign, the tax was less than tithe, and "except for the two taxes, there was no cross-winding." Within a few years, the treasury was full, and the people were rich, "so that the peace of Dading was thirty years." When Wan Yanyong ascended the throne, the country's population was only about 3 million, and 20 years later it increased to more than 6.7 million. During the Dading period, the political situation was stable and the finances were sufficient, so Wanyan Yong enjoyed the name of "Xiao Yao Shun".

On the second day of the first month of the twenty-ninth year of Dading (1189), Wanyan Yong died of illness in the Fu'an Hall in the Zhongdu Palace at the age of sixty-seven. Many people wept bitterly, and their voices of grief were everywhere. Due to the early death of the crown prince Wanyan Yungong, Yungong's son Wanyan Jing ascended the throne as Jin Zhangzong.

The name is Emperor Ming Renxiao, the emperor of Guangtian Xingyun, Wende and martial arts, and the temple number is Sejong, who is buried in the Xingling Tomb of Dafang Mountain.
