During the Qing Dynasty, only one man could be buried in the imperial tomb, even if he was a prince of the Heavenly Emperor, he could not be buried in the imperial tomb after death, and could be buried near the imperial tomb by the emperor's special will. However, in the history of the Qing Dynasty, there was really a prince who was buried in the imperial tomb after his death, and he was the eighteenth son of Kangxi, Yin Yuan.
In the forty years of the Kangxi Dynasty of the Qing Dynasty, Yin Yuan was born in the Forbidden City, and his birth mother was Princess Wang of Shunyi. Wang Shi was originally a Han woman in Jiangnan, and her cousin was Kangxi Fa Xiao Li Xu, during the southern tour, Li Xu, who was then a weaver in Suzhou, introduced his cousin Wang Shi to Kangxi, and Kangxi smiled and accepted it, and summoned Wang Shi to the harem.
Although the Wang clan was from a humble origin, it was quite favored by Kangxi at that time, and the Wang clan successively gave birth to three princes to Kangxi, namely the fifteenth son of the emperor, Yin Lu, the sixteenth son of the emperor, and the eighteenth son of the emperor, Yin. Kangxi was very fond of these three younger sons, and often took them on tour, especially the eighteenth son of the emperor, Yin Yuan, who accompanied his father at the age of 7.
In July of the forty-seventh year of Kangxi, Kangxi went out of the siege, and the eighteenth son of the emperor, Yin Yuan, was also in the list of accompanying princes, however, unexpectedly, on the way, Yin Gong contracted an illness, and his condition was once very serious. At that time, both Kangxi and the accompanying ministers were very worried, but the crown prince Yinrong was very indifferent to this and had no brotherly feelings, and Kangxi began to dislike the prince and even reprimanded him.
The reprimanded crown prince YinRong, instead of relenting, peeked into Kangxi's tent at night, an act that was exposed by the emperor's eldest son, Yin Zhen. At this time, Kangxi finally couldn't bear it, and immediately summoned the accompanying ministers to depose the crown prince Yinrong in front of everyone, and on the same day that Kangxi was deposed, the eighteenth son of the emperor, Yin, unfortunately passed away, only eight years old.
The eldest son was not filial piety, and the younger son died prematurely, which made Kangxi seriously ill, and Kangxi realized that he had neglected to discipline the prince for many years.
After Yin Yuan's death, Kangxi ordered him to be buried in Jingling Concubine Yamen, which was the place where many of Kangxi's concubines were buried, so why did Kangxi bury his son inside? Is it because he loves Yin Yuan the most?
Of course not, Kangxi's favorite should be the eldest son of the original Empress Xiaochengren, Chenghu, followed by the crown prince Yinrong, how can not take Yin's turn. Is it because Kangxi's favorite concubine Shunyi is yin's birth mother? Of course not, Kangxi's favorite was the fourth concubine of Hui yi de Rong. As for what the real reason was, I am afraid that only Kangxi himself knew it, no matter what, Yin Gong became the only prince buried in the imperial tomb.
Although Yin Gong died early, Princess Shunyi still had two sons, and the outcome of these two sons was still very good. The fifteenth son of the Emperor Yin yu was made the Prince of Yue by Yongzheng, and the sixteenth son of the Emperor Yin Lu received the weight of the emperors of the Yongzheng and Qianlong dynasties, and it is especially important to note that Yongzheng ordered Yin Lu to inherit the title of Prince Zhuang.
This Prince Zhuang originated from The fifth son of Emperor Taiji of the Qing Dynasty, Shuo Sai, who was originally called Prince Chengze and later renamed Prince Zhuang, because Shuo Sai's son Bo Guoduo had no sons to inherit the title, and Yongzheng ordered Yin Lu to inherit the title, and this prince was still hereditary, that is, we often call the Iron Hat King.
