This is mainly because the Song Dynasty had a lesson from the past and was afraid that its kingship would be destroyed by these princes, so it was very secure to sit on its own throne. So these princes were abolished in the Song Dynasty. Because in the early Song Dynasty, people in the Song Dynasty were not stable at that time, so Zhao Kuangyin chose to employ people around him as a way to stabilize the morale of the army from the beginning, so at this time Zhao Kuangyin handed over an important task to his children and let them hold very important positions.

However, although Zhao Kuangyin did this, it ushered in a bad result, that is, after Zhao Kuangyin's death, his younger brother usurped power and seized power. After that, the Song Dynasty began to re-formulate the personnel handling plan within the royal family. After that, the Song Dynasty was very strict with their royal children, whether it was monitoring or supervision. After that, the princes of the royal family in the Song Dynasty not only had no military power, but also had no actual duties. The best they can do is to use fiefs to ensure that you have enough food and clothes, and your reputation sounds good. And although many of them have the name of king, they actually have no real power, just like exile.

From the beginning, Zhu Yuanzhang of the Ming Dynasty imitated the previous people, and wanted to make the children of his imperial clan an important part of the country, enfeoffment them as vassals, and guard their respective vassal States, and everyone gave them certain military power. However, the consequence of this is that the historical events of warlord melee have begun again. Therefore, after the registration of Emperor Wen Jian, he also made certain arrangements for himself to deal with the children of the royal family internally.

But this time, although Wen Jian said it had been dealt with, it didn't work, and was finally defeated by Judy, the prince. When Judy became emperor, she also realized the seriousness of this matter, so she began to use her iron wrist to abolish the military power of Wang Zong.
