The key part of the sentence "Hanging in the Jade Belt Forest" in Daiyu's judgment lies in the three words "Jade Belt Forest". Its real connotation has several aspects:
First of all, these three words The character turned upside down became "Lin Daiyu", which is naturally a name homophonic to "Lin Daiyu". Cao Xueqin used this homophonic naming method a lot. This is the superficial meaning.
The second is its deep meaning, which is its original appearance "Jade Belt Forest". It means that the appearance of Lin Daiyu is due to the appearance of Jia Baoyu, that is, Fairy Jiangzhu came down to earth because of her benefactor, the attendant of Shenying, in order to repay the kindness of nectar, so she was passively "brought" down by him. I speculate that in the order of naming, Cao Xueqin didn't come up with "Lin Daiyu" first, and then figured out a homonym of "Lin Daiyu" and the meaning of "Jade Dailin". On the contrary, what Cao Xueqin first thought of was the rich and far-reaching myth of the Shenying Waiter and the Tears of Jiangzhu Xiaocao. Cao Xueqin only came up with the idea after confirming the meaning of "Jade" "bringing" "Lin" down to earth. "Yudai Lin", "Lin Daiyu" and "Lin Daiyu". In other words, the latter is a homophony of the former, rather than what we usually think of: "Lin Daiyu" first, then "Lin Daiyu" and "Yudai Lin". From a creative point of view, the design of this name is not an ordinary symbol. It reflects Cao Xueqin's overall concept, character relationships, fateful ending and profound meaning. These are the most important. Perhaps the girl whom Jia Baoyu loved in Cao Xueqin's original conception was not named Lin Daiyu at all, and he changed it when designing this myth of repaying tears.
So what does "hanging" mean? "Gua" has two meanings: one is "gua" and "depend", that is, Daiyu's parents died, and she lived in her uncle Jia Zheng's house and lived on her uncle; the other is "Jia" is a polyphonic and polysemous word. One represents business, pronounced ɡǔ, which generally refers to business and business people. The pronunciation of "Gua" in some Wu dialects is similar to the sound of "ɡuo", which is similar to the sound of "Jia" for merchants. Another main meaning of "Jia" is as a surname. Therefore, the meaning of "Gua" here has changed from the homophonic "Jia (ɡu)" to the surname "Jia (jiɑ)", which also means that after "Jade Belt (Zhu) Lin" descended to earth, "Lin" lived in the "middle" of Jia's mansion.
Noting the cultural gene of "Jade Belt Forest" will help us further interpret the artistic image of Lin Daiyu, because this "Jade Belt Forest" phenomenon continues to exist in Lin Daiyu. In other words, in the first eighty chapters, "Jade" continues to play the role of "leading" "Lin". This kind of driving situation can be seen almost everywhere. The most obvious thing is that in Chapter 23, two people read "The Romance of the West Chamber" together. It was Jia Baoyu who got the books from outside through Mingyan, including "The Romance of the West Chamber" and "The Peony Pavilion". Daiyu read it so enchantedly that she couldn't put it down. As a result, when Grandma Liu entered the Rongguo Mansion for the second time to drink, she couldn't help but laugh. He opened his mouth carefully and said, "I made a mistake," and was discovered by Xue Baochai on the spot. Afterwards, Baochai gave Daiyu "patient and meticulous ideological education" based on his own personal experience and the combination of reality and reality. If Daiyu had not read it, she would not have made this "mistake". So the root cause is that Baoyu got these books and influenced Daiyu. The reason why Daiyu never said "bastard words" to Baoyu was not only because she understood him, but also because she was influenced and infected by Baoyu's progressive ideas, so she didn't say anything, so she could gain Baoyu's "deep respect".
The same goes for Baochai. "The golden hairpin is buried in the snow", which means there is a gold hairpin in the snow, that is, Xue Baochai.
As for Baoyu, he was born with Baoyu in his mouth, hence his name
