In the eyes of later generations, Zhu Yunwen inherited his father's gentle good temper, full of bookishness and gentleness, but judging from some things he did, he was not a benevolent and weak emperor.
On the contrary, after becoming an emperor, Zhu Yunwen's personality was actually quite ruthless. Just after Zhu Yuanzhang's death, he launched a reform organization to forcibly cut the vassal, and without leaving any room, he directly reduced his thinking uncle to several names, and even forced the whole family of Xiang Wang to death.
But after Zhu Di sent his son as a hostage, Zhu Yunwen still didn't weaken the efforts to cut the vassal. And Zhu Yunwen's message at that time was that I should not be accused of killing my uncle. So the point of this sentence is not that Zhu Yunwen doesn't want Zhu Di to die, but that Zhu Di's death can't affect his reputation. This shows how cruel and vicious he is.
and the reason why he was defeated by Judy in the back was that he didn't understand Zhu Yuanzhang's ability. As long as you don't do anything else, the throne will be as stable as Mount Tai, but Zhu Yunwen is too smart.
Besides cutting vassals, Zhu Yunwen also raised the status of civil servants and suppressed military commanders and ministers with citizens, which led military commanders in many places to maintain a wait-and-see attitude towards this war. And Zhu Yuanzhang also cleaned many famous soldiers at that time, which led to no one available in Zhu Yunwen.
Therefore, from these aspects, Zhu Yunwen's final defeat to Zhu Di is not only his own fatuity and incompetence, but also his arrogance and complacency, thinking that his throne can always be secure. So he shouted the hearts of many ministers, so it is very natural to lead troops to revolt.
