In his lifetime, Kangxi not only achieved remarkable political achievements, but also had the highest fertility among the emperors of the Qing Dynasty, according to statistics, Kangxi had a total of 55 children, and 20 daughters. However, due to the limited medical level at that time, only eight really grew up, and among the eight princesses who grew up, the most loved by Kangxi was the third daughter, Princess Gulun Rongxian.

Through the study of the early history of the Kangxi Dynasty, it was found that the survival rate of the children born in the early days of Kangxi was particularly low, and before the birth of Princess Gulun Rongxian, concubine Zhang and Concubine Dong had already given birth to two daughters to Kangxi, but all of these two daughters died prematurely. At that time, the Qing dynasty royal family and the Mongol tribes frequently married, but Kangxi's daughters continued to die, which was very unfavorable to the Manchu-Mongolian marriage, so Kangxi took the daughter of his brother Changning to the palace to raise, and this adopted daughter was Kangxi's only adopted daughter, Princess Gulun Chunxi.
The entry of Princess Gulun Chunxi into the palace added a touch of vitality and vitality to the great Forbidden City, and subsequently, the harem was born one after another, and Princess Gulun Rongxian came to the world in this way, on the sixth day of the first month of May in the twelfth year of Kangxi, and it was Princess Rongjia who gave birth to Princess Gulun Rongxian.
Ma Jiashi was kangxi four years through the eight flags draft into the palace, after entering the palace she quickly won the favor of Kangxi, in the sixth year of Kangxi gave birth to Kangxi's first child, that is, the emperor's eldest son Chengrui, when Kangxi was only a fourteen-year-old teenager, but had already become a father, what is even more unexpected is that in the next ten years, Ma Jiashi gave birth to five more children for Kangxi, thus she became the concubine who gave birth to Kangxi the most.
Ma Jia gave birth to a total of six children for Kangxi, the only daughter being Princess Gulun Rongxian, the third daughter of the emperor. Ma Jia, who had made great contributions to the imperial family, was crowned twice in the 16th year of Kangxi and the 20th year of Kangxi, and was named Rong Concubine and Rong Concubine respectively. Under the favor of her mother, Princess Gulun Rongxian also won the favor of her father Kangxi, who in the thirtieth year of Kangxi, the 18-year-old third daughter of the emperor was named Princess Heshuo Rongxian, and then married to the Mongolian BalinBu, and the donkey was Urgun, the second son of Ozil, the king of Zasak Doro County.
To say that this Urgun is not an ordinary person, he is related to the Qing Dynasty royal family. Urgun's grandmother was Princess Gulun Shuhui (born to Empress Xiaozhuangwen), the fifth daughter of Emperor Taiji of the Qing Dynasty, and it was because of this relationship that he was able to marry the most beloved daughter of the Emperor Tianzi. After marrying Urgun, Princess Rongxian gave birth to a son and a daughter named Linbu, who later inherited the title of King of Zasak Doro County, and her daughter Borjigit married the Xian prince Yan Huang (Hauge's great-grandson, the fourth prince of Su) as Consort Fujin.
Kangxi forty-eight years, during the tour, the crown prince Yinrong behaved poorly, was deposed by his father Kangxi, for this reason Kangxi was seriously ill, when Princess Rongxian specially returned from the Ministry of Bahrain to personally take care of her father, which lasted for more than forty days, never slackened, which made Kangxi greatly moved, so he ordered Rongxian to be crowned princess of Gulun. During the Qing Dynasty, only the daughter born to the empress could be crowned princess of Gulun, and Rongxian's mother Ma Jiashi was just a concubine, which showed Kangxi's love for this daughter.
Princess Gulun Rongxian's husband Urgun was enfeoffed as king of Zasak Doro County in the 43rd year of the Kangxi Dynasty, and later led an army with the Qing army in the 58th year of the Kangxi Dynasty, and died in the army two years later. Princess Gulun Rongxian died in the sixth year of Yongzheng at the age of 56, and the princess was buried in the territory with Urgun.
More than two hundred years later, the tomb of Princess Gulun Rongxian was found in the Right Banner of Balin in Chifeng, Inner Mongolia, and what is unexpected is that Princess Rongxian was not only buried in a dragon robe, but also the body was well preserved, and the height was about 156 centimeters.
Moreover, on the south and east sides of the princess's coffin, there are also urguns and his son Linbu's urns, from which we can see that at that time, the Qing Dynasty royal family had accepted the custom of burial in the Central Plains, while cremation was still practiced in Mongolia, so we saw a strange scene.
