In the Ming Dynasty, every vassal had grain, stones and military orders. In Wang Fu, there is a prince guard command post, which is in charge of three military guards, ranging from 3,000 people to 6,543.8+0.9 million guards. The Nine Kings (Liao, Ning, Yan, Gu, Dai, Jin, Qin, Qing and Su) shoulder the heavy responsibility of defending against the intrusion of Mongolian nobles, so they have many guards. Wang Yan Judy, the fourth son of Peiping, supported 65,438+million troops, and Wang Ning Zhu Quan, the seventeenth son of Daning, "took 80,000 armour and 6,000 wagons". They are responsible for building cities and wasteland, training ordinary soldiers, patrolling key points and supervising the construction of military equipment in frontier fortress. The king of Jin and the prince of Yan went out of the village many times and defeated the remnants of Meng Yuan, which was especially important. The generals in the army are all under their control, and even the two kings are specially ordered to report small things to the court. Especially the prince of Yan, because of his outstanding achievements, Zhu Yuanzhang ordered him to "control the frontier horse" and occupied a unique position.
The expansion of vassal power will inevitably pose a threat to the central government. When Zhu Yuanzhang sealed the kings, a minister named Ye Boju pointed out that the influence of the princes was too heavy, and it would be too great to lose them after several generations. At that time, it was likely to lead to the tragedy of the "Seven Kingdoms Rebellion" in the Han Dynasty and the "Eight Kings Rebellion" in the Western Jin Dynasty, reminding Zhu Yuanzhang to "reduce the capital system, reduce guards and limit the territory." Zhu Yuanzhang not only refused to listen to advice, but put him in prison and died.
In the process of enfeoffment, he stipulated that all the blocked kings must leave the capital and become vassals when they arrive at the fief. Princes are not allowed to communicate with each other. Even if you enter the DPRK, you cannot come at the same time. One king must leave Beijing before another king leaves. The purpose of Zhu Yuanzhang's move was to prevent the kings from connecting with each other in series against the central authorities. Therefore, kings are vassals, which can be said to be "where will they go?" However, Zhu Yuanzhang's good intentions did not receive the expected consequences.
