The main idea of the story is: Jia Baoyu goes to visit Xue Baochai, who wants to see Baoyu's psychic Baoyu. When Yingying, Baochai's maid, looked at the words on the jade, she said that the gold lock with Baochai was only a pair, which led Baoyu to look at Baochai's gold lock and the result showed that it was a pair. See the eighth chapter of A Dream of Red Mansions. Through the plot of "psychic comparison", Baoyu saw Baochai's golden lock, which opened the prelude to the golden wedding. On the significance of the eighth chapter of A Dream of Red Mansions from Jin Ying, a psychic: Baochai and Daiyu are both semi-sour.

-Baochai said with a smile, "Japanese people say that your jade has never been carefully appreciated. I want to see it today. " As he spoke, he came closer. Baoyu also leaned down, took it off and handed it to Baochai. She held Baochai in the palm of her hand and saw it as big as a bird's egg, bright, moist and crisp, wrapped in five-color patterns. ..... After reading it, Baochai turned the front side over and examined it carefully. She said, "Don't forget, don't forget, the fairy Heng Chang." After reading it twice, he turned to Yinger and said with a smile, "Why are you still standing here staring blankly?" Yinger also smiled: "I heard these two sentences, but they seem to be a pair of words on the girl's collar." When Baoyu heard this, he quickly smiled and said, "So my sister has words on that collar, too? I also appreciate it. " Baochai said, "Don't listen to him, there's nothing to say." Baoyu said, "Good sister, what do you think of me!" Baochai couldn't stand him, because she said, "Someone gave me a few auspicious words, and I carry them with me every day. Otherwise, it will be heavy. What's the fun? " As he spoke, he unbuttoned his button and picked out the glittering golden wreath from the red coat inside. When Baoyu was busy holding the lock, he found that four words on one side and eight words on both sides made * * * two auspicious words. ..... Baoyu read it twice and read his own twice. Because of a smile, he asked, "Sister, these eight words are a pair with mine."
