What traditional ideas did A Dream of Red Mansions break?

Cao Xueqin wrote A Dream of Red Mansions to break the feudal ideology and traditional consciousness at that time, because the politics was decadent and the society was dark. This book describes the historical changes of four big families from prosperity to decline. At the same time, it also implied that the Qing Dynasty would eventually decline, so this book was banned at that time. There are many places in the book that break the traditional thinking. For example, Lin Daiyu and Jia Baoyu read The West Chamber under a tree. She will not support Jia Baoyu to pursue fame and gain, and love him silently in her own way. As far as her characters are concerned, Lin Daiyu is also beyond that era. She is different from ordinary women. She is brilliant and has her own ideas and opinions. She is sentimental and pities the petals' love for natural things, which shows her loveliness and naivety. From her every move, I feel that she is different from that world. Needless to say, Jia Baoyu was born with jade and loved being with women, saying that his daughter was made of water and his man was made of mud. Seeing his daughter makes him feel refreshed, but seeing a man makes him feel sick. In fact, Baoyu is only in contact with women in the Grand View Garden. But these women are all representatives of realistic women, which shows the uniqueness of Baoyu. It is also said in the book that they are vermilion grass and god waiters in the sky, so they are definitely not in line with reality. They are carefully portrayed by Mr. Cao to express their resistance to reality, but the tragic ending of the story also shows Mr. Cao's helplessness to reality.
