After returning to Chang'an, Li Xin took a short rest for two days before he began to go to the court to deal with political affairs. Since the Chinese New Year is coming up in two days, unless it is a particularly urgent matter, everyone will put aside the general matter for the time being, and prepare to wait until the New Year to deal with it.

In this way, time came all the way to the sixth year of Tianding, the first month of 365 AD!

Last year was a year worth recording for both Datang and the world, because in this year, the trend of the world has undergone earth-shaking changes. Datang jumped to second place in one fell swoop, squeezing the original second Yanguo down.

But the second place in Datang is not the same as the second place that Yan Guo won before, because after taking the Central Plains, Datang's strength is actually faintly on a par with Jiang Zuo.

After all, in addition to early development and fertile and flat land, it was also the center of gravity of the Central Plains Dynasty. This time, the land of the two states was taken, and the population alone increased the number of people in Datang by millions of people.

As long as the dividends of these demographics are brought into full play, then it is very likely that the strength of the entire Datang will soon jump to the first place.

Therefore, what Li Xin wanted to do at this time was to vigorously restore the economy of the Central Plains, and for this reason, he mobilized the strength of the entire Tang Dynasty and tried his best to support the construction of Youji and Hebei.

With the stability of the Central Plains, more and more people from the south and north began to return to the two states. After all, during the previous war, many of the people in these two places went to Pingzhou, Saiwai, Qingzhou and Jiangzuo.

It's hard to leave your homeland, and life in other places is not easy, if it's not because of helplessness, who wants to leave your homeland? Now that I have this opportunity, it is naturally better to return to my hometown.

At this time, on the land of the Central Plains, the Tang Dynasty government began to divide the fields and land, reduce taxes and give seeds and cattle, which in the eyes of ordinary people, but they all have a huge temptation ~ temptation.

Who doesn't want to have a good life, so many people are trying their best to move back.

At this point, the border of the Tang Dynasty extends to the Qinling Mountains, Funiu Mountains and the Yellow River in the south, the coast of the sea in the east, the Yanshan Mountains in the north and the grassland desert outside the Saiwai, and the eastern edge of the Qilian Mountains, Helan Mountains and the Qinghai-Tibet Plateau in the west.

Such a vast border can be said to encompass thousands of miles, and almost the entire north has been unified. Now there is only one place left, Pingzhou, and the westernmost Liangzhou boundary. As long as these two places are taken, it means that the entire north of the Yellow River will be completely unified.

But it is obvious that this is not the time to do this, so Li Xin is not in a hurry to do this.

However, Yan Guo was beaten to a cripple, which caused some different effects. The first one is Liangzhou, originally they were ministers to Jiangzuo, but they were also scared at this time, so Zhang Xuanliang sent envoys to Chang'an, and at the same time paid tribute to Chang'an.

In the same way as them, there is also the Qiu Chi State in the west, they also regard themselves as Jiang Zuo's courtiers, and at this time, in order to protect themselves, they can only send people to surrender to Li Xin.

Although this practice of marrying one daughter and two women seems a bit shameless, neither Jiang Zuo nor Li Xin has bothered with them so much at this time.

At least, after the nominal submission and submission, there will be no more trouble in Liangzhou and Qiuchi, which is a very beneficial thing for Li Xin's current plan.

On the first day of work after the New Year, Li Xin listened to the report of Wang Meng and others, and concluded the war situation of the previous year. Since the territory of Datang has greatly increased now, some things are set up like before, which is not very appropriate.

Therefore, Li Xin decided to adjust the administrative division, so that Datang gradually became a normal country and built a complete system.

The biggest adjustment is to divide the land of Datang into ten prefectures, including Yong, Qin, And, Si, You, Hebei, Dai, Shuofang, Ling, and Liang!

Among them, Lingzhou refers to the area of Helan Mountain and Ningxia, and the original counties such as Xuanjuan, Yuanwei, and Sanshui have been adjusted. Its approximate location is in the east and west areas of Helan Mountain, and several counties were divided from the original Shuofang land to Lingzhou.

As for Liangzhou, it is not the Liangzhou in the Western Regions, but refers to Jincheng, Xiping County, as well as Anyuan County, Xihai and other places are counted as Liangzhou. Moreover, the land of Youzhou has been slightly expanded, making the original land of Jizhou a little smaller.

As for the land of Sizhou, it refers to the areas of Hedong, Hanoi, Henan and Xingyang, as well as Shangluo. The scope of this place was originally very large, and this time Li Xin adjusted it and included some of it in the territory of Yongzhou.

In general, when the entire administrative division is divided in this way, it becomes much more reasonable.

Subsequently, each state appointed assassins, generals, and envoys, which were considered to have held the power of government, military affairs, and justice, respectively. These three officials were the highest-ranking leaders in a state, and they were the real feudal officials, and they had to be appointed by Li Xin himself.

The generals of each state are responsible for commanding the soldiers and horses of the whole state, and are ordered by the governors of the five armies and the military department. In addition, in the border areas, where the enemy country is in contact with, in the event of war, special personnel are often assigned to control it.

From this point of view, while ensuring the stability of the states to the greatest extent, it also minimizes the risk of the development of local forces and the self-respect of officials.

It just so happens that after the end of this war, a large number of meritorious people need to be rewarded, and a large number of these people will be promoted to suitable positions.

For example, generals such as Shao Zisong, Lu Guang, Pang Hui, Yao Chang, Shi Yue, etc., have contributed a lot in this war, so they will all be reused. Before, there was only one Daizhou general in the entire Tang Dynasty, and that was Yu Song.

In fact, at that time, Li Xin already had the idea of this kind of setting, but the timing was not right at that time, and now the time is just ripe.

Some of the original Taishou, or some of the servants of various departments, also got the opportunity to be transferred to other places at this time. For example, Ren Tong, because he did a good job in supporting the front line before, was promoted to the history of the state assassin this time.

Shao Zisong was appointed as the general of Jizhou, Shi Yue was appointed as the general of Youzhou, and Chen Kang was also appointed as the general of Sizhou. Basically, after the personnel arrangements in various places were gradually put in place, the follow-up to the war gradually came to an end.
