Why is the name Baoyu related to the names of Xue Baochai and Lin Daiyu?

Jia Baoyu was born with a piece of jade in his mouth, so the Jia family named him Baoyu. This jade has never left Baoyu's body. Many times, when Baoyu got angry, he said that he would smash the jade, but others stopped him, because everyone thought that the jade was magical and was used for protection. The golden lock worn by Xue Baochai is also called the winding in A Dream of Red Mansions. There are two versions about the origin of this golden lock in Cao Gong's works: the first version, in the eighth episode of A Dream of Red Mansions, is the first time that this golden lock appeared on the stage. The reason is that Xue Baochai wants to see Baoyu's psychic jade through the screen name, and Baoyu wants to see Baochai's golden lock after reading it. Baoyu read it and said that the eight characters on Baochai's lock were "a pair" with those on her psychic jade. At this moment, Yingying, Baochai's maid, said with a smile, "It's from the donkey-headed monk. He said it must be wrapped in gold. . . "。 Attention, everyone. Yingying is talking about the eight words on Baochai's golden lock, not the golden lock. Because if you want to stick it on gold, it should not be a golden lock (it is gold itself, why should you stick it on gold? Moreover, before Baoyu looked at the golden lock, Baochai herself said, "It was also a man who gave me a few auspicious words and told me to take them with me every day, otherwise it would be boring!" Second Edition: In the 28th episode of A Dream of Red Mansions, in which Xue Baochai was ashamed of the red musk deer string, Baochai mentioned to Mrs. Wang and others that "the golden lock was given by a monk, and only jade can be married in the future." Why are there two versions of the origin of the same golden lock? This involves the different psychology of Xue's mother and daughter in different periods. First of all, when this first edition came out, it was the season when Baochai and other draft girls came out. Although the Jia family is also a noble family with great wealth and power, how can it be compared with the royal honor? Therefore, the origin of the golden lock at this time is the most real, because Baochai is very likely to be selected at this time (or Aunt Xue and others very much hope that she can choose to enter the palace successfully), and there is no need to fabricate a lie like "marriage needs jade". Who knows if the emperor has jade? Ha ha. If you are elected, you will laugh at yourself. When Aunt Xue's second edition came out, the situation was very different. First of all, Xue Baochai had no choice (as can be seen from the gift that Yuan Chun gave her like Baoyu, if she chose, Yuan Chun would have the courage to make do with the emperor's future concubine and her brother). Second, Yuan Chun rose from an ordinary female official to a virtuous princess (according to the ancient system, this is already one of the four concubines). Since Xue Baochai can't be an imperial concubine, she will not lose as the future head of the Jia family. Third, Yuan Chundeng's reward-of course, this may also be mutually causal, that is, first Aunt Xue and others boasted about the magical origin of Baochai's lock in front of Mrs. Wang, and it was a perfect match with Baoyu's jade, and then let Mrs. Wang tell it to her, and then showed her attitude: an agreement was reached through holiday rewards. The support attitude virtually gave Xue mother and daughter confidence.
