1. Guo Ziyi retakes Chang'an
After eight years of the Anshi Rebellion, the Tang Dynasty poured its strength into encirclement, suppression and suppression, and drove the rebels from the south to the north, from the west to the east. After years of war, the Tang Dynasty's national strength was damaged and its vitality was seriously injured. The crusade against the rebels, the western army moved to the east, the western border defense, the military strength was empty, the Tufan army, taking advantage of the void, seizing wealth and plundering land, a large area of land, lost.
In 763 AD, the Tuchu army broke through the western frontier defense line and fought all the way, with great momentum and might, directly approaching Chang'an. The local military and political chiefs and envoys were afraid of wolves and tigers, first, they were afraid of defeat on the battlefield, and second, they were afraid of being framed by traitors. Looking east, looking west, lying on the side of the bridge watching the water flow, sitting on the top of the hill watching the tiger fight, no one dared to lead the army to block the invasion of Tufan.

The eunuch Cheng Yuanzhen gave Li Yu, the emperor of the Tang Dynasty, a crooked idea: Your Majesty, let's go, the Tubo army is approaching, Chang'an is in danger, self-preservation is supreme, stay in the green mountains, and are not afraid of no firewood. Emperor Li Yu of the Tang Dynasty listened to the eunuch rumors, took the harem concubines, eunuch ministers, and guards of the forbidden army with him, walked out of the palace gate, left the capital Chang'an, and took refuge in Shaanzhou (Shaanzhou in present-day Sanmenxia City, Henan Province).
Tianzi did not even want the imperial palace, the army also quietly withdrew from Chang'an City, the capital was not defended by an army, and the Tubo army drove straight in and occupied the capital of Chang'an. In the palace, the north and south halls, the east and west four palaces, the front and back of the house, the corners of the walls, inside and outside, turned over to the sky. Antiques are all taken, treasures are packed, gold and silver are better, and items are also collected. Not only that, the people of the capital have suffered a lot, and the large families have robbed them of their property; most of the people have lost their homes; they have no choice but to flee the wilderness. Inside Kyoto, tufan is rampant, dark clouds are shrouded, and people are turning over on their horses. Closed doors and locked doors, no trace of people, Chang'an Capital City, looted.
At the critical moment, Guo Ziyi, who had been dismissed by Emperor Xian, re-entered the sight of Emperor Li Yu of the Tang Dynasty, and ordered Guo Ziyi to re-emerge from his horse and go out on a campaign to recover the capital. Guo Ziyi was ordered to be in danger, not afraid of hardships, stepped on the war horse, raised the flag, and rushed to the battlefield. Guo Ziyi is the god of war on the battlefield, the veteran is out of the horse, a top two. He led his army to lantian, 100 miles from Chang'an, and stationed it. Adopt the tactics of small and medium-sized, out of nothing, bluffing, beating drums and shaking the flag during the day; lighting fires and smoke at night to confuse the enemy. He also used the tactics of the soldiers who were not tired of deception, it was difficult to distinguish between true and false, and created a plan to create public opinion, and the soldiers sneaked back to the capital in disguise and organized the people in the city to go around and say: "Guo Linggong's relatives have led a large army to fight!"

Guo Ziyi led the army well, sent troops strangely, had strange tactics, was famous far and wide, and was mighty and powerful, and the Tubo generals were afraid of him for three points. The generals thought left and right, weighed and weighed the family's bottom, and really couldn't beat him, so they withdrew their troops. Blowing the lamp to pull the wax roll Kang mat, slipping away. Pack up your backpack, carry your bag, flee without a fight, and withdraw from Chang'an. Guo Ziyi did not use a single soldier, did not spend a single shot or arrow, and recaptured Chang'an City, which had fallen for 15 days.
The eunuch Cheng Yuanzhen had a crooked idea again, not wanting Emperor Daizong To return to Chang'an, Kyoto, knowing that the ministers were all at odds with him, gritting his teeth in hatred, returning to the imperial court without good fruit to eat, and using clever words to persuade the emperor to make Luoyang the capital. Tianzi Li Yu really agreed.
When Guo Ziyi heard the news that Emperor Daizong Li Yu would not return to Chang'an for the time being, he was uneasy in his heart and wrote a letter to the emperor saying: Chang'an has always been the capital of the Tang Dynasty, 800 miles of Qinchuan land, evergreen in all seasons; Kyoto's outer defense line, sound military facilities, and dangerous terrain. Attack can be attacked, retreat can be defended. His Majesty's eastern tour was because of the harassment of the Tubo army, and now that the Tufan foreign tribes have withdrawn from Chang'an, what reason is there not to return to the capital City of Chang'an!
Emperor Tang Dynasty held the fold in his hand, looked at the above table carefully, said it conclusively, was loyal, was deeply moved, and burst into tears. To the ministers and attendants on the left and right: Ziyi's loyalty is visible, the minister of the society, and the blessing of the imperial court. He had already made up his mind and returned to the capital as soon as possible.
Emperor Daizong obediently returned to The Capital Division, guo Ziyi led the team to meet him, prostrated himself on the ground and pleaded guilty, and the emperor stopped the carriage, stepped off the dragon, and said: "This is all the fault of Yuan, and aiqing was not activated early, so it is to this point." After that, he also gave Guo Ziyi a death-free card "iron coupon", and invited a painter to paint a portrait of him in Ling Yan Pavilion in recognition of his military achievements in recovering the capital.
Second, Guo Ziyi rode back to the silk alone
When The servant Gu Huai'en put down the rebellion of An Shi, he was a fierce general under Guo Ziyi, a loyal vassal of the Tang Dynasty, and his family, 46 people died on the battlefield, martyred for the country, full of loyal martyrs. However, some eunuchs framed him for colluding with the Hui (hé).
In 765, he did not stop doing two things, and in anger, he really colluded with Hui Qi and Tubo and launched a rebellion. He also tricked Hui hui into saying that Guo Ziyi had been assassinated by the eunuch Yu Chao'en.
Coincidentally, on the way to march into Chang'an, the servant Gu Huai'en suddenly fell ill and died. The combined Forces of Hui and Tubo continued their attack until they reached Jingyang (泾阳, in present-day Xianyang, Shaanxi Province) and pointed their swords at the capital Chang'an.
Guo Ziyi was stationed in Jingyang, but there were not many soldiers and horses under his command, and he could not fight the enemy. Spies were sent to infiltrate the enemy camp to reconnoiter the military situation, and returned to report that since the death of the servant Gu Huai'en, the two armies of Hui Andui and Tubo had fallen out of agreement.
Guo Ziyi listened and decided to implement a counter-plan. Because the Hui generals had worked with him to quell the Anshi Rebellion, the two were very familiar and friendly, so he planned to win over the Hui people and isolate the Tubo army, making him unable to fight again.
Guo Ziyi sent his troops to use Li Guangzhan (zàn) as an emissary to lobby the Hui camp. Li Guangzhen saw the Hui capital Governor Ge Luo and said, "I am an emissary of Guo Linggong, and he asked me to ask you, tang dynasty and Hui are friendly states, why did you come to attack this time?"
Yao Ge Luo was very surprised and said, "No matter who sent you, after all, you are a messenger, how can you deceive me?" Wasn't Guo Linggong already killed? ”
Li Guangzhen used the whole body solution technique, his tongue was like a spring, his mouth was dry, and Yao GeLuo just didn't believe it, so he had to go back to his home and report to Guo Ziyi. Listened to the report. Guo Ziyi decided to personally go out on horseback and persuade the Hui people.

His subordinates proposed that the marshal lead 500 elite troops, but Guo Ziyi refused, saying: "Bringing more people will be a bad thing." So, with only a few retinue guards, he stepped on his horse and set out.
Before coming to the Huiyi military camp, the entourage of guards shouted loudly, "Guo Linggong is here!" Guo Linggong is here!"
Hui Qi's general Yao GeLuo heard the shouting and walked out of the military tent to see what was going on. Looking at it carefully, the marshal riding the war horse was really Guo Ziyi, and he shouted excitedly: Wow, it is really your old man! Hurriedly led his subordinates to salute Guo Ziyi with a fist.
Guo Ziyi got off his horse and walked to Yao Geluo to give a fist bump in return, and after greeting him, he said: The Hui army has made great contributions to the Tang Dynasty, why should it rebel now? But I am mentally prepared to be killed by you, and if this is the case, my generals will not spare you, and will desperately seek you to avenge me.
Hui Qi General Yao Ge Luo immediately said: Shame, shame, you said so, we really fell for the servant Gu Huai'en, thinking that Ling Gong and the emperor are no longer alive, and zhongyuan has no master, so we followed suit. We will not meet with the Ling Gong knife and gun, fight and fight!

Subsequently, Guo Ziyi shook hands with the Uighurs for the second time, signed a pact and reconciled, and attacked the Tubo army together. When the Tubo army got the news, it found that the signs were not right, so it immediately packed up its belongings and withdrew overnight.
