Zhu Yuanzhang was the first emperor of the Ming Dynasty. He was born poor and a beggar, so he was tolerant of the poor and strict with his own army. The health center system is actually a system he invented to support his own army. He once said, "I can raise millions of soldiers without spending people's money." This shows how proud he is.

What is a health center system? The officers and men of the health center are called military households, which are passed down from generation to generation, meaning that if the ancestors were soldiers, they would be officers and men of the health center from generation to generation. Before the Yuan Dynasty, some military households were established, which were accepted by the Ming Dynasty. Later, Zhu Yuanzhang ordered the official determination of domestic military households with the Yellow Book.

These military families own their own land. They don't need to eat people's food, but rely on their own efforts. These military households have their own land and regular food every month. Military households in charge of land reclamation should hand in rations on time every month and provide them to the garrison and local officials. Using this method, the Ming dynasty also maintained a strong military force at the local level and successfully reclaimed a large number of wasteland, which can be regarded as the welfare of the country.

Another purpose of Zhu Yuanzhang's adoption of this system was to disperse people's resistance. There were still many remnants in the Yuan Dynasty, so the government still faced many challenges if it wanted to stabilize the country. Zhu Yuanzhang's method was to emigrate in large numbers, and when he moved those people to other places, he lost the capital to make trouble, and he used the garrison to further disperse the people's power.

This system established by Zhu Yuanzhang is of great help to maintaining the stability of the country. First of all, the domestic army can be self-sufficient and will not bring great burden to the government. In addition, the strength of local troops in many health centers all over the country is still very strong, which ensures the local garrison, and it is difficult for foreign enemies to threaten the Ming Dynasty.
