Liang Fei's life in the palace is not satisfactory. Kangxi once denounced Yin Gui as "the bride's humble servant", which was a disguised dislike of Liang Fei's birth. In the fifty-first year of Kangxi, Liang Fei became ill, refused medical treatment and medicine, and died the same year;

There is a record in the imperial edict of Kangxi compiled by Yong Zhengdi: "When Yunyun's mother princess was seriously ill, she left Yunyun's last words saying: Your father always blamed me for being humble. I just wish I could die. I'll get tired of you one day. Therefore, he refused to take medicine. " It can be seen that the death of Liang Fei has a lot to do with Kangxi calling her a bitch of Xin Zheku. She didn't want to implicate her son, but chose this suicide-like way to end her life.
