1. Baoyu thought that Xiren betrayed him. Because Baoyu liked her, and Xiren didn't want to be the second aunt Zhao, she chose to marry Jiang Yuhan. So to say that Xiren betrayed Baoyu is to injustice Xiren.
2. It turned out that Xi Ren was Jia Mu's servant girl. He once served Shi Xiangyun and finally Baoyu. In the eyes of many readers, Xi Ren is the "murderer" who broke up the "Wood Stone Front Alliance" and killed Qing Wen and others. Admittedly, Xi Ren has always been aiming to become Bao Yu's aunt, and he is very good at finding help to remove the obstacles on his way one by one. However, all the calculations turned out to be futile, and she finally married Jiang Yuhan.
3. In the last 40 chapters of Gao E's sequel, Xi Ren was forced to marry Jiang Yuhan after Baoyu became a monk. Mrs. Wang and others thought that although she enjoyed the treatment of her aunt, she did not cross the Minglu Road, so she was not suitable to guard for Baoyu. In Gao E's continuation, Xi Ren even thought of committing suicide several times because he could not keep watch for Bao Yu. Finally, I saw the scarf exchanged between Baoyu and Jiang Yuhan before, and then I gave up the idea.
4. However, in the 87 version of Dream of Red Mansions, the process of Xiren's marriage was not described in detail. But after Baoyu came out of prison, he met Xiren by accident, who had married Jiang Yuhan at that time. When Xi Ren was grooming Baoyu, he said that she knew that Baoyu hated her. It's strange why Baoyu attacked people.
5. After Jia's house was copied, the women's wives either died or were sold, and the slaves were no exception. But the assassin did not seem to be implicated. According to the research of many scholars, it is believed that the real outcome of the assassin should be that he was afraid of being implicated or left for other reasons before the Jia Family accident. Later, the accident in Jia's house was believed to serve Baoyu and Baochai with her husband.
6. So Xiren said in the play that Baoyu hated her, probably because she betrayed the Jia family. Or because she used to be a person of Baoyu, and she had a very important position in Baoyu's heart, but she married someone else, and Xiren thought Baoyu could not accept it.
