How scientific was the ancient conscription system, and the whole people became soldiers at least earlier than the west 1000?

Every country has a strong army. In ancient times, the army consisted of civilians and slaves. Since the Han Dynasty, the system that all the people are soldiers has been implemented, so it is at least earlier than the west 1000 years.

From the Shang dynasty, the integration of military and agriculture was implemented. They usually farm and go to the army during the war. There are 18 people, and they are combat units. In the Western Zhou Dynasty, the army became a team, and joining the army was called enlistment. Later, in the Spring and Autumn Period, savages also went to military service, and more and more soldiers were serving. Savages are generally responsible for logistics work, while compatriots and ancestors are responsible for completing first-line combat tasks. During the Warring States period, the conscription system was implemented, mainly among young people, supplemented by women's infirmity. As long as a man reaches the age of 17 or is 5 feet tall, he will go to military service and can go home after the expiration of military service.

The Qin dynasty followed the conscription system in the Warring States period, and they also attached great importance to combat skills. The military system of the Han Dynasty was universal, at least earlier than that of the West 1000 years. At that time, as long as men were over 23 years old, they had to start military service. There are three types of military service, including the central army, border guards and militia. These three types are services in turn.

Later, it developed to the Yuan Dynasty, which was the most powerful time for martial arts. It is closely related to the military service system in which all people are soldiers. The reason is that there are Mongols, Han Chinese and Semu people. Mongolians have served for 55 years, but they can bring their families when they go out.
