Human personality is always very complicated, such as the Jianwen Emperor Zhu Yunjiao, who is recorded in history not only as a benevolent and kind young talent, but also as a very filial and good son and grandson. It is precisely because his personality is full of many positive energy that he stands out from Zhu Biao's many sons and becomes emperor.
When Zhu Yuanzhang was alive, he asked Zhu Yunjiao more than once how to deal with his uncles who were kings of the clan if they had different intentions, and Zhu Yunzhang replied very firmly: "With virtue and respect, with etiquette, we must not cut their land, and we must not change their people, and even raise troops to cut them." Zhu Yuanzhang was very satisfied with Zhu Yunjiao's answer, but it can also be understood that Zhu Yunjiao's loyal appearance deceived Zhu Yuanzhang.

Emperor Jianwen Zhu Yunjiao
Zhu Yuanzhang trusted this gentle grandson very much, but he did not believe that his sons were all good people who kept to themselves, especially Zhu Di, the King of Yan. Therefore, in order to prevent Zhu Di from rebelling in the future, he quietly left Zhu Yunjiao a secret message and handed it over to his most trusted eunuch for safekeeping.
If one day Zhu Di rebelled and ordered him to present the secret will to Zhu Yunjiao, if Zhu Yunjiao had the help of this person, Zhu Di would undoubtedly be defeated. If Zhu Di had not plotted a rebellion, then this secret decree would never have seen the light of day. Facts have proved that Zhu Yuanzhang expected well, but it was not Zhu Di who took the initiative to rebel, but the good grandson he was convinced of forcing Zhu Di to rebel.
We can understand that Huang Zicheng and Qi Tai and others instigated Zhu Yunjiao to cut the domain, but this is ultimately a family affair of the Zhu family, and if Zhu Yuncheng is resolutely opposed, it is useless for anyone to fool him. Therefore, it can only be said that under Zhu Yunjiao's kind and loyal appearance, there is a cold and ruthless face.
If it is a talented emperor, this is called the art of imperial power; if there is no talent, it can only be called a mediocre king. Zhu Yuanzhang left Zhu Yunzhang with a million elite soldiers, and the generals who led the troops were also luxurious, but they lost to the 100,000 soldiers and horses that Zhu Didong had cobbled together. But if Zhu Yunjiao has a little wisdom and strategy, he will not be defeated.
In 1402, after four years of the Battle of Jingnan, it finally ended with Zhu Di's great victory. When Zhu Yuanzhang's most trusted eunuch handed a treasure box to Zhu Yunjiao, he learned that Zhu Yuanzhang had already built a secret passage in the imperial palace. Zhu Yunjiao escaped from the city of Nanjing with this secret passage, and was eventually able to save his life.
However, when he escaped from Nanjing and looked through the box carefully, he found that there was a secret message pressed under the jade seal. After Reading the Secret Instruction, Zhu Yunjiao couldn't help but cry bitterly: "Or The Emperor Grandpa is smart, since there is such a desperate plan, why didn't you say it earlier?" Unfortunately, I was confused at the crucial time?! If he had known this, Zhu Di, the King of Yan, would undoubtedly be defeated! Zhu Yunjiao's words are by no means self-consolation after failure, if there is really the help of this person, Zhu Di has no possibility of success.
This person was Zhu Yuanzhang's fifteenth son, Zhu Zhi, the King of Liao. There are not too many records of Zhu Zhi in the history books, but if he was only a mediocre person, he would not have become one of the nine kings of the town guarding the border. The most crucial thing was that Zhu Yuanzhang knew that Zhu Zhi was very obedient and had the best relationship with the crown prince Zhu Biao, so he finally gave Zhu Zhi the title of King of Liao.
Geographically, the Liao king's fief was in the northeast of Beiping (the palace was in Guangning, now Beizhen, Liaoning), which was tantamount to inserting a sharp sword behind Zhu Di. Because Zhu Di's army was difficult to fight south, if Zhu Zhifa's troops occupied Zhu Di's base area of Beiping, and then attacked the Yan army with the southern army, would Zhu Di still have a chance of winning?
This secret decree should have been kept and disposed of separately, and once Zhu Di raised an army, it should be immediately seen by Zhu Yunjiao. However, it is a pity that Zhu Yuanzhang was probably old and confused, so he put this secret seal and the jade seal and the drawings of the secret passage of the palace together and handed it to the eunuch who was close to him, and only presented it to Zhu Yunjiao when the city of Nanjing was destroyed.
Or maybe Zhu Yuanzhang couldn't imagine that Zhu Yunjiao would be so confused, from a geographical point of view, if Zhu Di sent troops, the biggest threat would come from Zhu Zhi, the King of Liao. However, Zhu Yunjiao, fearing that the Liao and Yan kings' fiefs were approaching, summoned Zhu Zhi to the capital and cut off his guards.
Since Zhu Yuanzhang had left Zhu Yunjiao a secret edict, he would inevitably also leave a secret edict to King Zhu Zhiqin. Unfortunately, Zhu Yunjiao was not only confused, but also a big fool, when he cut off Zhu Zhi's guards, Zhu Zhi not only cooled his heart, but also saw that Zhu Yunjiao was definitely not a benevolent And righteous Mingjun, even if he had the ability to help, he would definitely not help. Simply close the door to see the hilarity, and whoever wins I will listen to whomever I want.
