As an academic viewpoint, "the combination of men and women" was first put forward by Mr. Yu Pingbo. Geng's forty-second general comment: "Although there are two firewood, everyone is one, and this magic pen is also. More than one third of the books have been written back to thirty-eight, so the writing is back, which makes them one. If you look at what Baochai said after Daiyu's death, you will know that the rest is correct. " In The Judgments of Twelve Women in Jinling, women and women draw a picture and a poem together, which is often used as auxiliary evidence.

Like "the combination of women and wear", there is also the problem of true and false Baoyu. What is the relationship between "truth" and "falsehood" As can be seen from the book, when Zhen Baoyu was young, he was exactly like Jia Baoyu. However, when I grew up, I seemed to turn to sex, perhaps because I was persuaded by the illusion of the police, as if I had become another person; At this time, Jia Baoyu had already "pulled back from the cliff".

A Dream of Red Mansions begins with a "fantasy" that changes from "stone" to "jade". Baoyu is a waiter in Shen Ying; The psychic Baoyu he wore was originally a big stone without talent, but it was turned into a beautiful jade by "magic". Perhaps, this stone "Ying" is the fate of "beautiful stone as jade". In a sense, it is a symbol of Baoyu's life.

Geng's 22nd double-clip criticism: "Xue and Lin Ruo read, don't they lose their original intention". If Chai and Dai are the same person, then true and false may also be the same person. There is no essential difference between "the combination of women and clothes" and "the combination of truth and falsehood". Jia Baoyu and Lin Daiyu were Zhen Baoyu and Xue Baochai when they were children. The so-called death of Daiyu turned into a fake jade, which may just symbolize a change in people. The so-called "the past never forgets the future". Jia Baoyu became Zhen Baoyu's "stone" and "jade", and Daiyu became Baochai's "wood" and "gold", which are essentially the same. One is "illusion" and the other is "magic pen", both of which present a changing process of change and then change.

Therefore, the dispute between Chai and Dai embodies the contradiction between ideal and reality, individual and society, emotion and reason. These are contradictions that each of us has to face, and they are of great universal significance. "Unity of men and women" is such a contradictory community that is both antagonistic and unified. It is "idealistic" to say that it is from "Daiyu" to "Baochai", or from fake jade to real jade. But for a specific person, it is only a matter of degree. The combination of women and wear or the combination of true and false is more like a real person.
