Why is it called princess grave?

Gongzhufen, this place used to have the tombs of two princesses of Renzong Jiaqing in Qing Dynasty. The cultural relics department conducted an archaeological excavation of the princess's tomb and made textual research with reference to historical materials, confirming that it was named after the two princesses of Emperor Renzong Jiaqing of the Qing Dynasty who were buried that year.

Princess Zhuang Jing and Master are buried in the east. She is the third daughter of Princess He Yugui, born in December of forty-six years in Qianlong. In November of the sixth year of Jiaqing, she married the Mongolian prince Sotnamuduobuji. Jiaqing died in March of 16th year, aged 3 1 year.

Princess Jing Gulun, the four daughters of Jiaqing, was buried in the west. She was born by Empress Xiao Shurui and was born in the forty-ninth year of Qianlong. In the seventh year of Jiaqing, she married the king of Mani Badala County in Tumote, Mongolia. Jiaqing died in May of 16th year, at the age of 28.

Due to the ancestral system of the Qing Dynasty, when a princess got married, she was not allowed to enter the imperial tomb or the in-laws cemetery after her death, and she had to build another grave. So there are many princess tombs in the suburbs of Beijing. Princess Heshuo and Princess Gulen died in the same year, only two months apart, so they were buried in one place.

Extended data:

1965, the planned line of subway 1 was completed, passing through the princess grave. At that time, there was no shield machine to build the subway, so it could only be opened from underground, and the tomb should also be excavated as a cultural relic. Although the tomb was stolen, many funerary objects were unearthed at that time, including weapons, Mongolian knives and silk jewelry, but there was no epitaph.

After investigating these funerary objects and the descendants of the tomb owner, historians finally found out that the princesses buried in the tomb were two princesses of the Jiaqing Emperor of the Qing Dynasty, ranking third and fourth respectively.

Later, a station (Gongzhufen Station) was also set up in the former site of Gongzhufen. Later, with the extension of West Chang 'an Avenue, it became a wide road. The original princess tomb has been submerged in the expansion of the city.
