杨贵妃
In novel "Dream of the Red Chamber", the two ladies beside the main character Jia Baoyu, Lin Daiyu and Xue Baochai had the images of Xi Shi and Yang Guifei. Both Lin and Xi Shi are sick and weak, Xue and Yang are plump and healthy. In chapter 30, Xue got angry because Jia said she is like Yang and she is chubby. The real reason is that Xue does not have a brother like Yang Guozhong.
