Setting fire to the palace so that everyone's bodies will not be identified is the best proof. His life was definitely not lost in that disaster, but escaped secretly. With Judy's character, if Emperor Wen Jian does not die, he will never feel at ease. During Judy's 22 years in power, she spent nearly 20 years searching for Emperor Wen Jian. According to my idea, in these 20 years, Judy must have found his emperor or known his whereabouts. Why do you say that? Below I list historical materials to verify my statement.
It is recorded in Biography of Hu Ying that since the fifth year of Yongle, Hu Ying has quietly traveled all over the country in the name of searching for immortals in Zhang Sanfeng. It was widely rumored that Wen Jian had gone to sea, so Judy sent Zheng He to South Asia seven times, but none of them were found. Hu Meng is the one who has been looking for the longest time outside. From the fifth year of Yongle to the fourteenth year of Yongle, whenever he went to a place for the first time, he told Judy the local rumors about his reign. During this period, Hu Yi's mother died, and Hu Yi wanted to go home to attend the funeral, but Judy refused.
In Yongle 17, Hu Meng went out again and didn't come back until Yongle 2 1 this time. At that time, Judy was not in Beijing, but in Fu Xuan. Hu Meng didn't stay in Beijing, but found Fu Xuan directly. Judy was sleeping when he arrived. I heard that Hu Ying has arrived. The emperor called urgently? . Hu Meng told Judy everything he knew. Miss four drums and you're out? Hu Meng talked until after 2 pm.
As can be seen from these records, Hu Ming must have the real thing to chase Fu Xuan this time. Judy's reaction is more suspicious. I was already asleep, but I got up and called for an emergency. I talked until late at night to get Hu Ying to leave. After that, Judy put aside her troubles and never looked for him again. So what news did Hu Ying bring to Judy this time? It's about his rule.
The news of death is Judy's most reassuring thing. The last time, Wen Jian had no intention of restoration. After reaching a certain place, there was no trace of it. Only in this way will Judy feel at ease.
Judy made great efforts to find Wen Jian, and even used the power of the Central Committee to send Zheng He abroad to find the whereabouts of Wen Jian. I think under such a large-scale search, as long as Emperor Wen Jian was not killed in the battle of Jingnan, it would be found by Judy. This is just my personal guess. As for the real result, only the parties themselves can understand it.
