What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
However, the lord of the darkness is partial to the security policy, and the air makes the hero cry. In 1141, the famous Southern Song general Yue Fei marched north with the momentum of destruction and decay, approaching the town of Zhuxian, which was only 20 kilometers away from the Song Dynasty capital Kaifeng, but just when the great achievement was about to be completed, Yue Fei suddenly received an edict from Emperor Gaozong of Song to order the retreat of the troops, resulting in the failure of the Northern Expedition.

The traitorous minister Qin Ju, at the behest of Emperor Gaozong of Song, executed this famous general on trumped-up charges. However, shortly after Yue Fei's murder, there was also a case in jinguo where a minister was killed on the charge of "false accusations".
The minister who was killed was named Yuwen Xuanzhong, who was originally a Zhongshu Sheren during the reign of Emperor Huizong of Song. After Emperor Gaozong of Song succeeded to the throne, he was ordered to send an envoy to the Jin Kingdom, but he never returned, stayed in the Jin Kingdom and became a Hanlin scholar, and then added officials all the way to the knighthood, and later simply became the Jin Guoshi.
This act of Yuwen Xuanzhong was also spurned by the southern Song Dynasty ministers. However, in 1132, the Southern Song Dynasty suddenly received a secret letter from Yuwen Xuanzhong, claiming that the Jin soldiers were about to enter Sichuan from Shaanxi.
The Southern Song Dynasty felt suspicious of this rebel's letter, but for the sake of safety, the Southern Song Dynasty still strengthened the defense of Sichuan and Shu on the grounds that "although the Yuwen Is secret in the void cannot be fully trusted, but the Jin people will not arrive in Huaidian for many years, they will certainly be contained."
The next year, the Jin soldiers did raid Sichuan and Shu, but because the Song army had already taken precautions, the Jin soldiers were defeated. After that, Jin Bing wanted to go south again, but Yuwen Xuanzhong strongly advocated peace on the grounds that the southern levy was expensive and laborious. The above-mentioned behavior of Yuwen Xuanzhong also made the Southern Song Dynasty believe that he had his homeland in mind, and gave the characterization of "serving the envoys in the void for a long time and keeping the festival unyielding".
However, Jin Wushu found the strangeness of the defeat. He wrote to Jin Xizong proposing to take back Yuwen's family members from the Song Dynasty, so that both his loyalties and traitors could be contained, and Jin Xizong immediately agreed.
When Yuwen heard that Emperor Enzhun had sent all his relatives to his side for a reunion, he was very unhappy, and he sensed that Jin Wushu was suspicious of himself, so he hurriedly wrote to the Southern Song Dynasty, saying, "If the Jin people ask for my family, they will all die in the rebellion."
However, Qin Ju and Song Gaozong insisted on sending all hundreds of Yuwen Xuanzhong's entire family to the Jin Kingdom, and at the same time, Qin Ju also deliberately leaked information on Yuwen Huanzhong's loyalty to the Song Dynasty.
Yuwen Xuanzhong was immediately imprisoned for treason, but the Jin people could not find any evidence, and finally forcibly burned more than a hundred mouths of Yuwen Xuanzhong's entire family, old and young, on the false charge of "too many books".
Although Yuwen Xuzhong suffered the tragic death of his entire family because of his loyalty to the Song Dynasty, the "History of Song" had a mixed evaluation of him, on the one hand, he believed that he had the Southern Song Dynasty in his heart, but on the other hand, he believed that he had done something that surrendered and lost control after all, "although Yun died unjustly, he also took it upon himself." There is also such a sentence in the later "Ci Hai": "Yuwen Xuanzhong, Jianyan prayed for the envoy to go to Jin in the second year, that is, to surrender, and then Jin Ting suspected that he was plotting rebellion and was killed." ”
Obviously, Yuwen Xuanzhong's use of betraying the Song Dynasty and lowering gold has also become a common criticism of him in later generations. It was not until the discovery of a later copper seal that this stereotype was completely overturned. In 1997, an old farmer in Harbin Acheng presented an ancestral copper seal with the words "Yuwen Xuanzhong" written on it.
Feng Yongqian, an expert from the Liaoning Archaeological Research Institute, had many surprises after careful study, because the copper seal in yuwen's void is in the shape of a coffin, and the printing surface is also engraved with a person, wearing an official uniform but his neck is bound by a rope, and the copper seal has neither a seal nor a lift.
Experts believe that this is exactly the manifestation of Yuwen's loyal mentality in the void, although he was demoted by Song, he never really became a subject of the Jin Kingdom, and his purpose in doing so was actually to endure humiliation and burden and lurk for a long time. Therefore, Feng Yongqian wrote an article overnight entitled "Overthrowing an Unjust Case in History by the Discovery of a Seal", which is bound to redefine the hero behind Yuwen Xuanzhong.
