The soldiers of Wuchuan Legion, on which Yu Wentai divided Guanlong, were mainly composed of the People's Insurgents of all ethnic groups in Guanlong. Plus the Liu Fang Xianbei soldiers who later entered the customs with Emperor Wei Xiaowu, the total strength of the Western Wei Dynasty was at least 40,000 to 50,000. However, with the continuous war with the Eastern Wei Dynasty, it became more and more difficult for the Western Wei Dynasty to replenish its troops, and the number of Xianbei people living in Guanlong was also small. Therefore, Guan Long's close friends, the dependent population of the Han people, were recruited as soldiers, led by local prestigious family figures. In order to coordinate the relationship between Hu and Han, keep close contact between commanders and soldiers, improve the soldiers' sense of identity and enhance the combat effectiveness of the army, Yu Wentai implemented the system of officers and men in the sixteenth year of the Western Wei Dynasty (550). The system of government soldiers took the form of tribal soldiers in the early Tuoba period. "After thirty-six generals with high merit and ninety-nine with low merit, their soldiers also changed their surnames." In other words, regardless of Han people or other nationalities, all the commanders and fighters were given the old surname of Xianbei tribe, and their commanders and fighters were renamed by the head coach. And modeled after Tuoba's early eight-part system, he set up an eight-pillar general. Prior to this, Yu Wentai was the general of the Eight Pillars State. He was the commander-in-chief of Chinese and foreign armies and had been in charge of the army. Yuan Xin, another general of the imperial clan in the Northern Wei Dynasty, only hung in name and had no real power, so the actual officers who led the troops were Liuzhuguo, each with an army, which was the Sixth Army. Under the Six Pillars State, there are two generals in each pillar state, a total of twelve generals; Under each general, there are two government offices, a total of 24 government offices, which serve the 24 th army; There are two instruments under each government, a total of 48 instruments; There are also leading officers such as viceroy, handsome viceroy and viceroy. The troops of government soldiers are each equipped with 1000, so there are 2,000 government troops, 4,000 general troops and 8,000 general troops in Zhu Guo, with a total strength of nearly 50,000. Government troops are still under the command of President Yu Wentai. The early government soldiers included Xianbei soldiers and Guanlong military households, while the township soldiers led by Guanlong Haoyou had no ordinary civilian households. Government soldiers belong to the army, are not included in the people's register, and do not bear taxes. Generally, they stay in the hospital for half a month. Half a month of training. Take turns serving and going out in wartime. During the period of Emperor Wu of the Northern Zhou Dynasty, in order to expand the source of soldiers, the target of recruiting officers and men was expanded to first-class civilian households. Later, it expanded to ordinary families. Because government soldiers can be exempted from taxes, they have been gathering people. Therefore, it is said in history that "people (Han people) in the late Xia Dynasty were all semi-soldiers." The number of government troops rose sharply, and by the time the Northern Zhou Dynasty destroyed Qi, there were 200,000 government troops. During the Western Wei Dynasty, the power of government soldiers was in the hands of Prime Minister Yu Wentai. Therefore, although the government forces appeared as "no trips" at that time, the leadership was not in the hands of the emperor.
During the period of Emperor Wu of the Northern Zhou Dynasty, the name of the sergeant of the government soldiers was changed to "Guan Shi", and the leadership was returned to the emperor, making the government soldiers a veritable guard.
The main body of the military system in the Western Wei and Northern Zhou Dynasties was the officers and men system, but officers and men were not the only army at that time. In addition to the government soldiers, there are also troops such as the palace guards, the town guards and the state and county soldiers.
