At first, An Lushan wanted to personally lead his troops to attack Tongguan, but when he arrived in Xin'an, he learned that something had happened in Hebei and returned. The rebel general Cai Xide led 10,000 troops from Hanoi to the north to attack Changshan.

Wushen (23rd), Rongwang Li Wan died, and Xuanzong gave him the title of Prince Jinggong.

In this year, Tubo Zanpu Qili Su Long Hunt Zan died, and his son Suo Xi Cage Hunt Zan succeeded him

In the spring, on the first day of the first lunar month, An Lushan proclaimed himself the Emperor of Dayan, changed the year name to Shengwu, and appointed Da Xi as the servant, Zhang Tongru as the Zhongshu Order, and the noble and solemn as the Zhongshu Shilang.

At this time, Li Sui arrived in Suiyang, and had tens of thousands of soldiers under his command.

Bingchen (the second day of the first month), Xuanzong appointed Li Sui as the envoy of Henan Jiedu, and Xu Yuan, the former governor of Gaoyao County, as the Taishou and defense envoy of Suiyang. Shang Heng, a native of Puyang, raised an army to attack An Lushan, appointed Wang Qiyao, a native of the same county, as the former governor of Yaqian, conquered Jiyin, and killed An Lushan's general Xing Chaoran.

Yan Gaoqing sent his son Yan Quanming, together with Jia Shen and Zhai Wande, to Beijing to present Li Qincuo's head to the imperial court and escort He Qianqian and Gao Miao.

Zhang Tongyou cried and pleaded: "My brother Zhang Tongru is a general of the rebel army, and I beg to enter Beijing with Yan Quanming to save the lives of our family." Yan Gaoqing was moved and agreed to his request.

When he arrived in Taiyuan, Zhang Tongyou wanted to be attached to Taiyuan Yin Wang Chengye, so he asked Wang Chengye to detain Yan Quanming and others, and made another statement, exaggerating his own merits and belittling Yan Gaoqing, and then sent another envoy to the imperial court.

Yan Gaoqing has only been raising troops for eight days, and has not yet prepared to guard, the rebel generals Shi Siming and Cai Xide led their troops to the city, Yan Gaoqing hurriedly asked Wang Chengye for help, Wang Chengye had already stolen his merits, and hoped that the rebels would capture Changshan, so they supported the army and did not save it.

Yan Gaoqing led his troops to fight hard day and night, and the arrows were exhausted.

On the eighth day of the first month, the rebels captured the castle of Changshan. The rebels indulged in the soldiers and killed more than 10,000 people, captured Yan Gaoqing, Yuan Luqian and others and sent them to Luoyang.

When the envoy sent by Wang Chengye arrived in Beijing, Xuanzong was very happy, and worshiped Wang Chengye as the general of Yulin, and more than 100 of his subordinates were knighted. The imperial court also recruited Yan Gaoqing as Wei Weiqing. Before the appointment arrived, the city had fallen to the rebels.

Yan Gaoqing was escorted to Luoyang, An Lushan rebuked him and said: "You were originally Fan Yang Hucao, I appointed you as a judge in the imperial court, and in a few years you were promoted to Taishou, what am I sorry for you, you actually want to raise troops against me?" ”

Yan Gaoqing scolded An Lushan angrily and said: "You were originally a shepherd Hu slave in Yingzhou, and the Son of Heaven promoted you to be the envoy of the three festivals, with deep kindness and great favor, what is there that is wrong with you, but you rebel?" I have been a courtier of the Tang Dynasty for generations, and the official positions of Lilu were all given by the Tang Dynasty, although you were appointed by the imperial court, how can I follow you to rebel! I am a traitor for the country, but I hated that I didn't kill you, how can I say that I am a rebellion? You stinky dog, why don't you kill me soon! ”

An Lushan was very angry when he heard this, tied Yan Gaoqing and Yuan Luqian to the pillars of the middle bridge, and scraped them to death with a knife. Yan Gaoqing and Yuan Luqian scolded until death. Yan Gaoqing's family was killed by An Lushan, and more than 30 people.

After the rebel generals Shi Siming, Li Lijie and Cai Xide conquered Changshan, they led their troops to attack the prefectures and counties that did not surrender, and slaughtered them in the places they passed, and Ye County, Guangping, Julu, Zhao County, Shanggu, Boling, Wen'an, Wei County, Xindu County and other counties fell into the hands of the enemy one after another.

Only Raoyang Taishou Lu Quancheng did not surrender, and Shi Siming and others led troops to surround Raoyang. Hejian Justice Li Huan led 7,000 troops, and Jingcheng Governor Shi Li sent his son Li Xi to lead 8,000 troops to rescue, but they were all defeated by Shi Siming.

Xuanzong ordered Guo Ziyi to withdraw the army that surrounded Yunzhong, return to Shuofang, and increase his troops to prepare to recover Tokyo. And another general was selected to lead a part of the army out of Jingcheng Pass and pacify Hebei.

Guo Ziyi recommended Li Guangbi.

In Guihai (the ninth day of the first month), Xuanzong appointed Li Guangbi as the envoy of Hedong Jiedu, and assigned 10,000 Shuofang soldiers to his command.

Jiazi (the tenth of the first month), Xuanzong added Ge Shuhan as the left servant and Tongping Zhangshi, and the original official position was the same.

Xuanzong set up the envoy of the Nanyang Festival, appointed Lu Jiong, the Taishou of Nanyang, to serve as this position, and led 50,000 soldiers from Lingnan, Qianzhong, and Xiangyang to be stationed in the north of Yexian County to guard against the southern invasion of An Lushan.

Lu Jiong asked Xue Yuan (Xue Yuan was the elder brother of the original crown prince Li Ying's concubine) as the Taishou and Defense History of Yingchuan, and Pang Jian (Pang Yu's great-grandson) as the deputy envoy.

On the 11th, An Lushan sent his son An Qingxu to lead an army to attack Tongguan, but was repelled by Ge Shuhan.

In February (the second day of the first month), the imperial court crowned Li Guangbi as the Taishou of Wei County and the envoy of Hebei Province.

In February, Shi Siming and other rebel generals had surrounded Raoyang City for 29 days, and had not yet taken it, Li Guangbi led more than 10,000 Fan Han infantry and cavalry, plus 3,000 Taiyuan crossbow fighters out of the Jingcheng Pass.

Jihai (15th), Li Guangbi's troops went to Changshan, and the Changshan regiment trained 3,000 soldiers to kill the rebellious Hu soldiers, and captured An Siyi out of the city to surrender.

Li Guangbi said to An Siyi: "Do you know that your sin deserves death? ”

An Siyi did not speak.

Li Guangbi said again: "You have been on the battlefield for a long time, see if these troops of mine can defeat Shi Siming?" What should I do now? If your plan is desirable, I will not kill you. ”

An Siyi said: "Your soldiers and horses are coming from afar, the soldiers are tired, and they suddenly clash with a strong enemy, I am afraid it will be difficult to resist, it is better to lead the troops into the city, prepare early, first deploy for deployment, and then send troops." Although the rebels are elite, they are difficult to last, and if they lose, they will be discouraged, and then they can be defeated. Shi Siming is now in Raoyang, less than 200 miles away from here. I sent him a letter asking for help last night, and it is estimated that the vanguard will arrive tomorrow morning, followed by a large army, so you must keep an eye out for it. ”

Li Guangbi was very happy when he heard this, so he loosened his ties for An Siyi and immediately moved his army into the city.

Shi Siming learned that Changshan was lost, and immediately lifted the siege of Raoyang to save Changshan.

Before dawn the next day, the forward troops had reached Changshan, and Shi Siming and others led a large army to follow, a total of more than 20,000 cavalry, approaching the city.

Li Guangbi sent 5,000 infantry to attack from the east gate, but the rebels desperately blocked the city gate and did not retreat.

Li Guangbi ordered 500 crossbowmen to shoot at the top of the city, and the rebels were forced to retreat.

Then Li Guangbi divided the 1,000 crossbowmen into four teams, and fired one team after another, but the rebels could not resist and retreated to the north of Dao.

Li Guangbi sent 5,000 people armed with spears and guns to form a square formation out of Daonan and lined up on both sides of the Hutuo River.

The rebels attacked with cavalry many times, but they were all repelled by Li Guangbi's crossbowmen, and most of the centaurs were shot, so they had to stop the attack and retreat to a truce to wait for the infantry. At this time, some villagers reported that the rebels' 5,000 infantry marched from Raoyang to Changshan, walking 170 miles day and night, and had reached Fengbi to the south of Jiumen, where they were probably resting.

Li Guangbi immediately sent 2,000 infantry and 2,000 cavalry, and quietly marched along the Hutuo River.

Shi Siming learned that the infantry had been wiped out and the situation was not good, so he led his troops to retreat into the Nine Gates. At that time, seven of the nine counties of Changshan County were surrendered to the official army, and only Jiumen and Gaocheng were still occupied by the rebels. Li Guangbi sent his general Zhang Fengzhang to garrison Shiyi with 500 troops, and the rest of the counties sent 300 people to guard them.
