In 763, just in this year, the Anshi Rebellion that had tormented the Tang Dynasty for eight years was finally put down, and everyone thought that the Tang Empire would return to the right track, but no one expected that in the next year, Gu Huai'en, the great hero who quelled the Anshi Rebellion, rebelled against the Tang, and the entire empire fell into turmoil again.
Although Hegu Huai'en was a member of the Tiele clan, he was loyal to the Tang Dynasty, and his family had a total of forty-six martyrs martyred for the country, and The Servant Huai'en even married two daughters to Hui Hui and his relatives, which can be said to be full of loyal martyrs, and Tang Suzong, in order to show his merits, included them in the Ling Yan Pavilion.
However, with the pacification of the Anshi Rebellion, although the world was stable, the hearts of the Tang Dynasty royal family were never stable, and they could no longer trust the military generals, especially the Hu people, as before. Emperor Suzong of Tang and Emperor Daizong of Tang were all exceptions, Guo Ziyi rose and fell many times, Li Guangbi rose and fell, and even Ming Ming was given death. The tragedy of the servant Gu Huai'en is that he is not only a military general, but also a Hu people military general, or a Hu people military general with great merit.
The lessons left by An Lushan and Shi Siming were too profound, but in 762, an even more unfavorable event occurred for the servant Huai'en. In this year, dengli khan personally led 100,000 cavalry south, and at this time Shi Chaoyi had not yet been completely pacified, so the main military forces of the Tang Dynasty could not be transferred back. The whole Tang Dynasty was very frightened, and everyone did not know what Hui Hui was going to do. Emperor Tang, who had just ascended the throne, had no choice but to send someone to contact Dengli Khan in the name of the Laojun and ask what was going on. However, Dengli Khan made a very inexplicable request, that is, he wanted to meet with his father-in-law, the servant Gu Huai'en. After all, a khan came to him with 100,000 people to kill, and then just to meet with his father-in-law and talk about home? Even if the servant Gu Huai'en believed, then the Tang Dynasty Emperor had to believe it. But there was no way to do this, the 100,000-strong army was there, and Emperor Tang Dynasty could only give the servant Huai'en an iron scroll to avoid death and express absolute belief in Aiqing's loyalty, and then let the servant Huai'en talk to his son-in-law. This Dengli Khan may really miss his father-in-law, and he withdrew after talking.
No one knows what the real purpose of Dengli Khan's visit was, and history does not record it, but Dengli Khan has made a miserable mistake for his servant Huai'en. Originally, Emperor Tang Dynasty was not at ease with the military generals, and now this happened again, although he did not say anything on the surface, but that cold eye had begun to stare at The Servant Gu Huai'en.
In 763, without any evidence, the eunuch Luo Fengxian falsely accused the servant Gu Huai'en of colluding with Hui Hui to plot rebellion. At this moment, the tight heart of the servant Gu Huai'en was suddenly cracked, because the servant Gu Huai'en knew that the Tang Dynasty Emperor Believed in eunuchs more than they trusted the military generals, and that there was no way for the servant Gu Huai'en to prove his innocence by "plotting rebellion". In the face of Pei Zunqing, who was sent by the Tang Dynasty, the servant Gu Huai'en was crying while holding his thigh, and the grievances and heartaches in his heart all turned into tears at this moment. However, although Pei Zunqing repeatedly said that "Your Majesty trusts you, and the imperial court believes in your loyalty", the rift has long been formed, and it can be eliminated with a few words. The servant Gu Huai'en did not dare to return to Beijing from then on, for fear that once he went, he would die without a place to bury, after all, there were many things in history.
There were more and more suspicions and controversies about the servant Gu Huai'en in the court, and the servant Gu Huai'en was even more afraid to return to Beijing, which fell into a strange circle, the imperial court did not trust the servant Gu Huai'en, so the servant Gu Huai'en did not dare to enter the capital to defend, and the servant Gu Huai'en did not enter the capital, which made the court more suspicious, and the rift between the two sides became deeper and deeper. In the end, gugu Huai'en sent his son to attack Xin Yunjing, who had framed him. The purpose of the servant Huai'en is very simple, Lao Tzu is so miserable by you, then you don't have to think about it. However, the son of The Servant Gu Huai'en was beheaded by the Tang Army in this military operation, and there was no room for maneuver, and the impulsive Servant Gu Huai'en decided to completely oppose the Tang.
In 765, the servant Gu Huai'en, who had been depressed for a long time, led hundreds of thousands of people, including Hui Hui and Tubo Tuguhun, to attack the Tang Dynasty, but when the army reached the halfway point, the servant Gu Huai'en died of illness in the army, and the rebel army was defeated by Guo Ziyi.
The servant Huai'en may really have all kinds of grievances and reasons to have to rebel, but rebellion is rebellion. The mother of the servant Huai'en could not accept her son becoming a rebel, so she carried a knife around to hunt down and kill the servant Huai'en, to eliminate the harm to the country. Emperor Tang dynasty believed that "Huai'en is not rebellious, and is misunderstood by the left and right", and has never regarded it as rebellion.
