Cheng Meng Yan land to control the world, Zu Xing China Daming Qiang, Zhu Teng Dragon Pulse marched to the north of the desert, Andi Qijing was difficult to raise from the eagle.
During the feudal dynasty period, in order to spread the branches and leaves, the imperial family created three palaces, six courtyards and seventy-two concubines for the emperor of the dynasty to ensure that the emperor's family's children and grandchildren were full of halls and incense.
Taking a step back, even if these children do not become emperors, they can defend their country. Therefore, there are many emperors in history who have many children after ascending the throne.

It is worth mentioning that Zhu Di, as a famous monarch in The history of our country, did not give birth to a son and a half daughter in his 22-year imperial career, which made the world very confused.
What is the reason for this? For this matter, there is a palace maid who told the secret behind it before being executed by Zhu Di, which may refresh your understanding of Zhu Di.
In 1360, during the great battle between Chen Youyu and Zhu Yuanzhang, Zhu Di was born. Because Zhu Yuanzhang had been paying attention to the war on the front line, he did not pay much attention to the child until 7 years later, when he officially named his son "Zhu Di".
From a young age, Zhu Di was very intelligent, especially his military ability was very prominent, and he was a rare general. In those years, he also continued to follow his uncles and uncles to the south and the north, combining theory and practice well.
At the age of 17, with his excellent performance, Zhu Di was appreciated by Zhu Yuanzhang and was sent to a foreign country as the king of the domain. At first, Zhu Di's place of office was in Fengyang, but later he went to Beijing to guard the frontier for the Ming Dynasty.
During that period, Zhu Di was ordered to participate in the task of rebelling against the Northern Yuan many times, and made great achievements. At the same time, he also took advantage of this opportunity to establish his own forces in Beiping, laying the groundwork for the later Battle of Jingnan.
Originally, according to normal circumstances, the throne of the Ming Dynasty was inherited by Zhu Biao. Unfortunately, Zhu Biaoying died young, and the emperor's throne fell into the hands of his son Zhu Yunjiao.
In 1398, The Hongwu Emperor died, and a year later Zhu Yunjiao succeeded to the throne. At that time, at the instigation of Qi Tai, Huang Zicheng and others, Zhu Yunjiao ordered the cutting of the domain with tough means.
As a result, the power of the kings of Zhou, Dai, Min, and Qi was successively stripped away, and during this period, "the King of Xiang set himself on fire, and Yu was deposed as a Shuren", and under layers of persecution, Zhu Di decided to launch the Battle of Jingnan and replace him.
It is said that during Zhu Yuanzhang's reign, due to the wanton massacre of military generals, which directly led to the lack of major generals available to Zhu Yunjiao in the early stages, coupled with the departure of the children of the Ming Dynasty royal family and Zhu Yunjiao, Zhu Di's Battle of Jingnan achieved great success.
After 3-4 years of struggle, Zhu Di finally entered the city of Nanjing, and Zhu Yunjiao's whereabouts are unknown. Since then, Zhu Di has taken his place as the third emperor of the Ming Dynasty, known in history as the "Yongle Emperor".
In later life, Zhu Di opened up the territory to the outside world, cultivated politics for the inner Ming Dynasty, and built the Ming Dynasty into a world top power, a prestigious and famous lord.
It is worth mentioning that throughout the second half of Zhu Di's life, since he ascended the throne and became emperor, no child was born until his death, which is very puzzling.
Chronologically, Zhu Di's last child was born in 1392 AD and was named Zhu Gaomu. After that, Zhu Di fought against the Northern Yuan and launched the Battle of Jingnan, which is understandable if there is no time to have children.
However, the year 1402 AD– 1424 AD – was the reign of Zhu Di. As we all know, the emperor has three palaces, six courtyards and seventy-two concubines, coupled with the ancient concept of "many children and many blessings", Zhu Di should have more children.
At the same time, Zhu Di was only about 42 years old at that time, and his physical condition still had the opportunity to have children. If this is the case, why is there such a "contradiction" as mentioned above?
In this regard, there are many rumors in the folk, which roughly means that Zhu Di's imperial origin is not correct, and he was cursed by "cutting off his children and grandchildren", so he never had children after he ascended the throne, which is the punishment of heaven for him.
If we lived in ancient times, because of the limitations of our vision, we would have believed in this kind of "god and ghost words", but from the current scientific point of view, the so-called "curse" is not credible at all.
Even more, if we push forward ten years, that is, in 1392, Zhu Di has not given birth to a child for 32 years, and you must know that 32 years old is the most energetic time for men.
For this question, many years later, a palace maid gave the answer before dying, and this answer was also surprising, enough to refresh many people's three views of Zhu Di.
In the Korean "Records of the Lee Dynasty", there is a record of Zhu Di, roughly stating the reason for his inability to have children, and the information recorded in the book is roughly as follows:
After becoming emperor, Zhu Di married a Korean woman as a concubine (Kwon Concubine) and was very fond of her. However, this concubine died at the same time, and Zhu Di was furious about it.
Coincidentally, another of Zhu Di's concubines said that Concubine Quan was poisoned by Lü Shi, and in a fit of rage, Zhu Di killed many people. Perhaps in retaliation, at this time someone reported that "another concubine" had an affair with the eunuch.
As the emperor of a country, Zhu Di was actually given a green hat by his concubine, and in his anger, he killed a large number of palace people to vent his anger, and a palace maid said such a sentence before she died.
She said: "My own family is in decline, so the private young temple people, what a blame!" The general meaning of this sentence is that Zhu Di's physical condition is not good, and he cannot meet the seventy-two concubines of the Three Palaces and Six Courts.
In this case, as a female palace maid and concubine, what is the sin of finding other men? After all, everyone has their own physiological needs, and you can't meet them.
It can be seen from such a sentence that Zhu Di's inability to have children is not a folk "curse", but a problem with his body, especially his ability to procreate.
From this, we can infer that perhaps during the Battle of Zhu Dijing, he was injured because of the fierce war, so he lost his fertility before ascending the throne, so that no child was born in the 22 years of his reign.
Even earlier, such as during the battle against the Northern Yuan, Zhu Di lost his reproductive function, so that he had no children since 1392.
For such a thing, many men are now difficult to talk about, Zhu Di as the emperor of a country, he can not say this matter, to his own face to smear, so the history books of the Ming Dynasty also do not have this record.
It can be imagined that when the palace lady exposed this secret of Zhu Di, it undoubtedly touched the dragon's reverse scales, and her fate could not be imagined to be very good.
As the third emperor of the Ming Dynasty, as a well-known "Yongle Emperor" in China's history, there was such an unspeakable "physiological problem" in the later years of his life, and it is estimated that Zhu Di himself was somewhat sad.
