The development of human body should follow certain natural laws. Men only enter the stage of sexual maturity at the age of 20, and their physical functions develop well, which is the basis of longevity.
However, the private lives of the princes and grandchildren of the Ming Dynasty were very disorderly. Many experienced personnel when they were twelve or thirteen years old, and their physical development was not perfect. Premature sexual experience will destroy their physical function. When you are young, you can't see anything in the world. Once you pass 30, you can clearly show it.
The descendants of the Yellow Emperor were born earlier. Some princes became fathers at the age of 12 or 13. They didn't live long, and the children were born with birth defects. After a round of harem, this small lattice was basically hollowed out. Longevity is very difficult.
The emperors of the Ming Dynasty were not particularly diligent. Emperor Wanli did not go to court for 20 years, which is a wonderful work among emperors. However, the political system of the Ming Dynasty allowed this huge country to maintain its basic operation, so there would be no serious consequences. Therefore, the emperor was tired of reading the throne, which was obviously not suitable for the emperor of the Ming Dynasty.
In fact, the most industrious dynasty of the emperor should be the Qing Dynasty. The emperor really got up early and went to bed late. He had no freedom and was very strict in the management of the harem. This may be because he learned a lesson from the Ming Dynasty, so the emperor of the Qing Dynasty broke the short-lived spell and most of them could die. However, in the late Qing Dynasty, the average life expectancy of the royal family was greatly reduced, so it was corrupt to let them follow the old path of the Ming Dynasty.
The private lives of the nobles in the Ming Dynasty were extremely decadent. Three wives and four concubines are just a common phenomenon, and there are more women outside the establishment of concubines. Princes live better than others, and the ladies around them are antagonistic and ruined their lives under the influence of wine and color.
In fact, it is not only the Ming dynasty, but also the emperors of all dynasties. However, this problem was more prominent in the Ming dynasty, which may be related to Zhu Yuanzhang's humble origin, lack of aristocratic background and excessive indulgence of future generations.
The ancients thought that it was lucky to have many children and grandchildren, especially in the Ming Dynasty, the number of direct royal families was always relatively small. Therefore, they also encourage premature sex, hoping to strengthen the royal family. However, this wish will eventually fail. Without scientific guidance, family talents will wither.
