Huangshi Qi Zilin Yong
Lin Yong, born in the 31st year of Qianlong, is the youngest son of Qianlong. It is said that Lin Yong is very lazy and idles about all day. Ganlong doesn't like him. Lin Yong died in the 25th year of Jiaqing at the age of 55.
Princess Gulen and Huang's seventh daughter Jing.
The seventh daughter of the emperor, born in the 21st year of Qianlong, had no chance to be named Princess Gulen, but she was named Princess Gulen and Princess Jing because the emperor found her a good husband and because of the relationship between her husband and the family. But after five years of marriage, she died at the age of twenty.
Huang Jiunv Heshuo Princess Heke
Huang Jiu's daughter was born in the 23rd year of Qianlong, and her mother, Wei Jiashi, married Zalantai in the 36th year of Qianlong, and died at the age of 23.
The princess was greatly favored and gave birth to six children for Qianlong, but she was not made queen before her death. However, after being abolished, Qianlong appointed Wei Jiashi as the agent of the imperial concubine, just like the queen, but without the title of queen. As for why she was not named Queen, it was probably for the safety of Wei Jiashi and the prince, so I just didn't protect them in this way.
