Why is xiren called huajieyu in A Dream of Red Mansions?

Xiren, a character in China's classic novel A Dream of Red Mansions, is the daughter of twelve women in Jinling and the first of the four beauties in Baoyu's room. Xiren's original name is Pearl (Cheng Yi's original name is Jolie). Appearance: Xiren is very picky, with a long face and a beauty. According to Mrs. Wang, although her appearance is slightly inferior to Qingwen, she is also second-class in the room. Since childhood, he was sold into Jia's family because of his poor family. He used to be Jia's mother's maid, and later served Shi Xiangyun for several years. Grandmother Jia liked Xiren's kindness and filial piety, so she married him to Baoyu. Mrs. Wang took her as a backup candidate for her aunt and gradually became the head of Baoyu's maids. Seeing that her surname was Hua, Baoyu took the meaning of Lu You's poem "Flowers smell like warmth suddenly" (A Dream of Red Mansions will suddenly be changed to Japanese) and renamed it "Xiren". As an important girl in A Dream of Red Mansions, Xiren has always been the most controversial female image in the book. She finally married the actress Jiang Yuhan.
