Although it shows that Emperor Renzong Zhu Gaozi reigned for only ten months, he was highly respected by historians and gave high praise, believing that "the year of heavenly leave, the recuperation of Han Hao, and the prosperity of Moralization, wouldn't it be better to be with Wen and Jingbi Longya."
The so-called Wen and Jing, that is, the Han Wen Emperor and the Han Jing Emperor, the wen jingzhi rule pioneered by these two emperors is known as the first prosperous era of feudal society and is admired by historians of all generations.
Zhu Gaozi only served as emperor for ten months, but he was praised by historians so much, which is enough to prove that he really did a lot of achievements in those months of his reign, so his death was so lamented and regretted by historians.

Zhu Gaozi was 47 years old when he died, and for people of that era, this age can no longer be regarded as "in prime".
His death was not so strange, and he had been in poor health.
From the perspective of modern medicine, Zhu Gaozi should be an obese patient, and his obesity has even affected his daily activities in the later stages.
A few steps can make him tired and breathless, not to mention that his legs and feet are not convenient, and he has to be supported by someone to be able to walk normally.
Because of this, Zhu Di has actually always disliked Zhu Gaozi, even if you are fat, you still have bad legs and feet, how to see there is no imperial style!
Among Zhu Di's sons, if anyone is the most like Zhu Di, then it is definitely not the second eldest Zhu Gaoxu.
Zhu Gaoxu was quite brave and good at fighting, and if he had not led thousands of elite horses to arrive in time during the Battle of Baigou River, Zhu Di might have been captured by Zhai Neng, and there would have been no later Yongle Emperor.
In the Battle of Dongchang, Zhu Di was once again defeated, and had to flee alone, but Zhu Gaoxu led him to help in time, which turned defeat into victory.
Zhu Di repeatedly wrenched himself in danger during the Battle of Jingnan and was repeatedly saved by Zhu Gaoxu, so Zhu Di was more inclined to let Zhu Gaoxu take over his class.
Zhu Gaoxu also thought that he was more suitable to be Zhu Di's heir because of his outstanding merits, so he had been openly and secretly competing with Zhu Gaoxu and wanted to compete for the position of crown prince.
Zhu Di also once thought about deposing Zhu Gaoxu and making Zhu Gaoxu crown prince, but because Zhu Gaozi was the eldest son of a concubine and did not make a mistake, whether he stayed in Beiping in the early stage or nanjing in the later period, his administrative ability was quite respected by the courtiers, so the courtiers also always opposed Zhu Di's idea.
The reason why Zhu Gaozi survived to the end, in addition to the support of his courtiers, was that he gave birth to a good son, that is, the later Ming Xuanzong Zhu Zhanji.
Before Zhu Zhanji was born, Zhu Di once had a dream, dreaming that Zhu Yuanzhang gave him a jade plate and then said to him: "The descendants of the heirs will be eternal." ”
After Zhu Zhanji's full moon, Zhu Di took a look, hey, this boy is still quite handsome, and then remembered the dream, so he sighed and said: "Erying is overflowing, Fu Wu dream." ”
Although Zhu Zhanji was a little greedy, he was really very clever, and the reason why Zhu Gaozi was able to sit firmly on the throne of the crown prince was somewhat inseparable from Zhu Di's love for Zhu Zhanji.
When Yongle was eight years old, Zhu Di also deliberately made Zhu Zhanji the emperor's grandson, which meant that Zhu Zhanji also became the heir to the imperial throne, and he was also telling Zhu Gaoxu that even if Zhu Gaoxu could not become emperor, there was still Zhu Zhanji, and it was not your turn to stand on Gaoxu, you died this heart!
This played a lot of role in Zhu Gaozi's sitting on the throne of the crown prince, at least it made more people firmly determined to stand on Zhu Gaozi's side.
Zhu Di himself often said to Zhu Gaozi, "Zhan Ji, this boy, will definitely be a Peaceful Heavenly Son in the future!" Is the hidden meaning of this statement still explicit?
Therefore, after Zhu Gaozi ascended the throne, it was also natural to make Zhu Zhanji the crown prince.
Although it is said that Zhu Gaozi had more chips in his hands after his son Zhu Zhanji was made the emperor's grandson, Zhu Gaozi still did not dare to slacken off in the face of the unpredictable Zhu Di and the ambitious Zhu Gaoxu.
Zhu Gaoxu never hid his desire to take the wife, after Yongle was crowned king of Han in the second year, he directly ran to confront Zhu Di, what crime do I have, you want to send me to Yunnan thousands of miles away? Saying that he would not go to Yunnan, Zhu Di could not do anything with him.
Later, Zhu Gaoxu went to Zhu Di again and asked Zhu Di to transfer Tiance Wei to him as a guard, the word "Tiance" was not simple, thinking that Li Shimin was a general of Tiance at that time.
Zhu Gaoxu wanted Tiance Wei, didn't he just want to be the "Li Shimin" of the Ming Dynasty?
Therefore, don't look at Zhu Gaozi, although he is the crown prince, he has always been in a highly nervous mental state, for fear that one will be accidentally abolished by Zhu Di.
It is precisely because he is in such a highly nervous mental state that Zhu Gaozi estimates that he can scare himself out of the disease without illness, coupled with various complications caused by his obesity, such as hypertension, coronary heart disease, etc., Zhu Gaozi's physical condition is not a rare thing.
From this point of view, Zhu Gaozi should also be a person with a short life.
The reason why Zhu Gaozi died suddenly within a year of becoming emperor was that in addition to his physical condition, he was a good emperor.
What does it mean to be a good emperor? It means he has to work hard and hard!
Zhu Gaozi's physical condition is the most taboo is also hard work, once overworked, it is easy to suddenly burst some fatal diseases, such as heart infarction, cerebral infarction and other diseases.
Therefore, behind Zhu Gaozi's sudden death, there is no conspiracy, and there is no need for any conspiracy.
