Before Qianlong succeeded to the throne, he already had three daughters, but only one of these three daughters survived, she was the third daughter of the emperor, Princess Gulun and Jing, princess Gulun and Jing were actually the eldest daughters of Qianlong, because her mother was Qianlong's original Empress Xiaoxian, so she was also Qianlong's only surviving concubine.
On May 24, 9th year of Yongzheng, Princess Gulun and Jing were born in the Western Second House of the Forbidden City, and since her father Hongli was the heir of Yongzheng King, Yongzheng also attached great importance to this imperial granddaughter and ordered her to be raised in the palace, and the person responsible for taking care of Princess Gulun and Jing was Princess Qin of Ningshou Palace, that is, Concubine Chunyu Qin of Kangxi.
Princess Gulun and Jing can be said to have been born with a golden key, and in the year when she was four years old, her father Hongli inherited the throne of the Qing Dynasty as the Qianlong Emperor. After Qianlong succeeded to the throne, he broke the custom of the imperial daughter being crowned princess only when she was about to marry, and when she was about to be crowned princess of Gulun, throughout the entire history of the Qing Dynasty, only Gulun and Jing princesses could enjoy this treatment.
Moreover, when Hejing was very young, Qianlong began to look for her objects, and the final choice fell on a young prince of the Mongolian Korqin tribe named Sebuteng Balejul. What is the origin of this Sebutem-Balejul? It turned out that he was the grandson of the first Prince of Darhan, Manzhu Xili (the fourth brother of Empress Xiaozhuang), and the grandson of Princess Gulun Duanmin of Shunzhi, so he and Princess Gulun and Jing could be said to be the right person, and they were close to each other.
When Sebuteng Balejul was nine years old, Qianlong made him the Duke of Fuguo and took him to the palace to raise him, so that Sebuteng Balejul studied with the crown prince. In March of the twelfth year of Qianlong, the 16-year-old Princess Gulun and Jing married Sebuteng Balejul, generally speaking, the duke who married the prince of the Mongol tribe returned to live in the territory, but Qianlong and Empress Xiaoxian were reluctant to love their daughters away from themselves, so they made an exception and let Princess Gulun and Jing stay in the capital and built a princess mansion of the Gulun rank for them.
Princess Gulun and Jing were also very affectionate with Princess Gulun and Princess Buteng Balejul, and after their marriage, they gave birth to at least five children, including three daughters, namely Dagege, Sangege and Sigege, of which Dagege married Qianlong's grandson Miande (son of Yong huang) as Concubine Fujin, and Sigege married Qianlong's grandson Fengsheng Jilun (son of Princess Heshuo and Jia). In addition, Princess Gulun and Jing also gave birth to a son, and Qianlong was very fond of this grandson and personally gave him the name: Erzhetmur Erkebabai.
However, Princess Hejing lost her mother (Empress Xiaoxian) only one year after she was married, and since then, as the only concubine, she has been with her father Qianlong, and Qianlong also hopes that this only concubine can live in peace, and in the year when Princess Hejing was 24 years old, Qianlong specially rewarded her with a treasure house (Liuhejing-), and gave her daughter 5240 gems and jade amulets, which shows qianlong's attention to this concubine.
On June 28, 1957, Princess Gulun and Jing, who had accompanied his father for 61 years, died of illness at the age of 62 , and Qianlong ordered him to be buried with his entourage , Butten Balejul , on the eastern outskirts of Beijing.
However, according to the regulations, Princess Hejing needed to bury her crown back to the territory, and Qianlong gave her the name Princess Mausoleum.
In ancient society, only the emperor's mausoleum can be called a mausoleum, Qianlong actually called his daughter's tomb a mausoleum, which shows the status of Hejing in his father's heart, and later the princess mausoleum was renamed Gongzhuling, and Princess Hejing was called the only princess used to name the city in the Qing Dynasty.
