After the fall of Goguryeo and the establishment of the Andong Protectorate, the old Goguryeo region was governed by a policy of local feudal rule similar to that of regional ethnic autonomy in later generations. Pen, fun, pavilion www. biquge。 There is a fundamental difference between the local administrative institutions established after Emperor Wu of the Han Dynasty destroyed the Manchu Dynasty.

The Goguryeo city, which was surrendered without being captured by the Tang army, was still entrusted with the original position of its city lord Datang, but the official name of Datang was changed. All the cities captured by the Tang army were served as the chief officials of a city by the Goguryeo magnates who had contributed to the Tang Dynasty.

The four-level administrative rule policy of the Andong Metropolitan Protectorate established by the Tang Dynasty over Goguryeo: Metropolitan Protectorate-Metropolitan Governor's Office-Prefecture-County, except for all the officials of the Metropolitan Protectorate were all Han Chinese, the chief officials of the other three-level administrative institutions were all Goguryeo, supplemented by Han officials to assist in governing the locality.

The Anton Prefecture had the power to appoint officials, levy taxes, and military authority over the entire Andong region. Most of the officials of the current Andong cities are the first protector Xue Rengui, according to the policy of the imperial court, to appoint Goguryeo people who have contributed to the Tang Dynasty, and those cities that surrendered are not among them.

In the early days, the Tang Dynasty garrisoned 20,000 troops in Andong, and these 20,000 troops were Tang troops transferred from the mainland, excluding the original defenders of the cities. The defenders of Andong Fortress were controlled by the Goguryeo who served as the governor and assassin, and the Metropolitan Protectorate had the right to requisition.

When Xue Rengui was transferred to Longyou to defend Tibet, he transferred most of Andong's garrison, which gave Silla and Goguryeo the opportunity to restore the country and set off wave after wave of restoration.

Most of the Goguryeo governors, assassins, and county commanders who had contributed to the Tang Dynasty were unreliable when the Silla general Sha Luo, the old Goguryeo general Gao Yanwu, and other anti-Tang Goguryeo rebels came to attack.

The Silla Goguryeo coalition army marched to the interior of Liaodong in two ways, and the partial division set off from the domestic city defended by Gao Yeonwu, who had surrendered to Silla and opposed the Tang Dynasty, and the main force crossed the Yalu River and lightly captured the cities of Bozhuo, Wugu, and Daxing.

After the Xingao coalition army entered Liaodong, eleven states in the eastern Liaodong region opposed the Tang Dynasty and surrendered to Silla, and the military and political officials of seven states fled without a fight in the face of the anti-Tang Goryeo army.

As a result, the main force of the Silla army was still in Wugucheng, and all the eastern Liaodong regions fell except for the prefectures in western Liaoning, the Fuyu Prefecture in northern Liaoning, and southern Liaoning.

The Goguryeo army on the north road attacked Yanjin Prefecture, and the south road even hit Shicheng in southern Liaoning. If it weren't for Li Yu's coincidental arrival, the cities captured by the Goguryeo rebels had not yet been consolidated, and the anti-Tang cities and the Silla army had not gained full trust. The communication between them was not smooth, and the calculation of the arrival time of the Tang army was inaccurate, and Li Yu was not calculated to arrive in Liaodong in the critical March of their uprising.

As soon as they arrived in Anshi, the Goguryeo army that had not been long before Zhan'an City was wiped out, and the Goguryeo rebels who came from other roads to Liaoxi immediately shrank back after hearing about it, and many anti-Tang cities started to sit on the mountain and watch the tiger fight. After all, the news of their anti-Tang Dynasty did not spread except for the Silla people and Gao Yanwu in the Black Bone City.

They thought that the Tang Dynasty was unaware of their anti-Tang actions, and after Li Shangdan and Xue Ne raided the Black Bone City at night, Sha Yu fled in embarrassment, and then searched for the surrender table of these people to Silla from the City Lord's Mansion of the Black Bone City.

Li Yu sneered after getting these tables, these things that eat inside and out, and those cowards who run away without a fight.

In the northeastern part of Liao, all the cities from Fufeng City to the domestic city, which runs from northwest to southeast, are either the former governors and assassins who rebelled against the Tang Dynasty or were occupied by the Goguryeo rebels.

Due to the lack of troops, Li Yu did not send troops to this place to recruit and suppress them, and only after resting for a period of time after the Battle of Wugu to consolidate the line from Anshi to Bozhuocheng did he send troops south to exterminate several Goguryeo rebels.

Recaptured the rebels captured and abandoned by the original assassin Shi Chengcheng, Mianyue, Yayue, Houhuang, Jilizhou, and Yincheng, and opened the passage to Beisha City and Qingnipu in southern Liaoning.

Due to Li Yu's four victories in four battles, Shicheng in southern Liaoning and Yanjin Prefecture in northwest Liao, which connected Xincheng Prefecture and Northern Buyeo Prefecture, were not occupied by the Goguryeo army as historically.

After four great victories, it is time to resolve the chaos in Liaodong after gaining a foothold in Liaodong. If the hidden dangers of Liaodong were not solved, Li Yu would not be able to transfer troops south to pacify the two of Jianmu, Cen and Anshun, and defeat the Silla people.

The so-called easy first and then difficult, now most of the cities in southern Liaoning except for Beisha, Shicheng, and Jian'an are in the hands of Li Yu. However, Maigu and Xinyue, the two states that had secretly surrendered to Silla before, had not yet been resolved, and they thought that they had not been discovered by Li Yu for their anti-Tang actions, and after Li Yu achieved the great victory of Da'anshan, they sent envoys to congratulate Li Yu like other governors and assassins.

After the two hidden dangers in southern Liaoning are resolved, troops can be sent north in June to solve the problems in northern Liaoning, and then they can go south to the Korean Peninsula.

It's a pity that the Jian'an Governor's Mansion is still in the hands of the Goguryeo people, and the current Governor Gao Xuan is also loyal to the Tang Dynasty, but Li Yu still has a stalk in his heart, after all, even the Goguryeo people are not his cronies.

Even Li Yu's current wartime Andong Zhisuo Anshi was a state under the jurisdiction of the Jian'an Prefecture Governor's Office, and the county governors and county orders in Liaonan Prefecture such as Beisha and Shicheng were native Han people, which made Li Yu quite recent.

When Li Yu usually discussed the situation in Andong with the generals, he complained more than once about the imperial court's original arrangement for the local administration to appoint those Goguryeo people as the governors of the first capital, the governors of the prefectures, and the governors of the prefectures. Moreover, from the governor to the county order, it is still hereditary, commanding the soldiers and horses of the city under his control.

The result? When the remnants of Goguryeo rebelled everywhere, as soon as the Silla army came, half of the Goguryeo people were ordered to surrender to the enemy, a quarter of the officials became deserters, and the other quarter guarded the cities in Liaoxi and Liaonan that were captured by the Tang Dynasty in the early years.

What Li Yu didn't know was that after the great rebellion of Goguryeo in history, Li Zhi did not think to learn a lesson, and even abolished all the Han officials arranged in the cities in the Andong area, and delegated all military and political jurisdiction to the Goguryeo people in exchange for no more rebellion.

The rebellion is no longer a large-scale rebellion, but this move caused the Tang Dynasty to last for decades, countless dead soldiers, and countless money and food, if the Great Andong region did not get any benefits, it was easily out of the control of the Tang Dynasty, and became an independent small kingdom in Liaodong, and was finally annexed by the Bohai State.

Now Li Yu wants to use his strong soldiers and horses, and the power of the capital protector of the Andong Metropolitan Protectorate appointed by the imperial court to reverse the evil consequences of Liaodong caused by the wishful thinking of his father and the princes of the imperial court. Those officials who fled without a fight were swept to the end, and the prefectures and counties under their original jurisdiction were replaced by their own people.

After Li Yu recaptured the city they had abandoned, these Goguryeo cowards shamelessly ran to Anshi with the letter of appointment from the Tang Dynasty and asked Li Yu to send someone to escort them back to continue their original positions.

Because it was covered with the seals of the three provinces of the Tang Dynasty and the Ministry of Officials, the word hereditary was written on the document, which made Li Yu hate it and scolded a bunch of pigs in the court.
