First of all, judging from the general environment of the ruling and opposition parties, Zhu Yunwen had just ascended the throne at that time, and Zhu Yunwen's teacher felt that the power of the vassal king at that time was too great, and wanted to take the idea of weakening the power of the vassal king and ensuring centralization. At this time, Judy's brothers were weakened by the young Zhu Yunwen early, and they were either exiled or placed under house arrest, surrendering all their military and political power. If Judy doesn't hand over the relieving here, there is only one word to die, but if he hands over the relieving. So Judy's situation at that time was whether he rebelled or not. Therefore, Judy decided to pre-empt Jun Qing.
On the other hand, from Judy's personal point of view, Judy wants to be emperor. Let's talk about following Zhu Yuanzhang to conquer the world. Zhu Yuanzhang had many sons, but only two of them can really be called good soldiers. One is Wang Ning, and the other is Judy. Wang Ning gave up the relieving early, went home, disarmed, and returned to the field, preparing for a lifetime in troubled times.
However, Judy is an ambitious person. He followed Zhu Yuanzhang to farmland and learned a lot from General Xu Da, so he was unwilling and didn't want to wronged himself. After all, Zhu Yuanzhang doted on Zhu Yunwen, not because Zhu Yunwen was talented, but because Zhu Yunwen was the son of his eldest son Zhu Biao, so Judy was already very upset. But I was afraid of my father Zhu Yuanzhang's ability, and I still knew his weight, so Zhu Yuanzhang didn't dare to rebel when he was still alive, but Zhu Yunwen was a little brother in front of him, so I decided to give it a try, and finally the rebellion succeeded.
