He had direct contact with Jia's family, but did not include Dai Yu and Xue Pan, teachers who sheltered and killed people. Mainly because the stone idiot owed Guan Yin, he took him to the yamen, sold his fortune, copied his collection of ancient fans to honor Jia She, and began to walk around Jia Fu more and climb Jia Fu's big trees.

The main characters in A Dream of Red Mansions and the development of some important plots are all related to the appearance of this character. According to the myth, Jia Baoyu was born in the world of mortals with a monk, but his formal meeting with readers came from Leng Zixing's mouth: "I don't want to have another son in the future, which is even more strange. As soon as I was born, I had a colorful jade in my mouth with a lot of handwriting on it, so I was named Baoyu. " However, the first person who made an unusual understanding of Jia Baoyu was Jia Yucun's theory of "two houses" of good and evil. Then, just the other two protagonists, Lin Daiyu and Xue Baochai, came to Jiafu, which was related to Jia Yucun. Not to mention Xue Pan, a lawless idiot. Like a devil's shadow, he always follows Jia's footsteps. He appears and disappears from time to time, but in his prosperity, it always brings bad luck to some people. No matter for Jia Baoyu or the whole Jia family, he will always be like a disaster, which makes people hurriedly escape. For Jia Baoyu, he became the touchstone to distinguish between trade-offs, while Lin Daiyu never said anything to make him close to Jia Yucun, but regarded him as a confidant. For Jia Jia, it became a cold mirror of the world. Jia Sheshi, a fool, buried the trouble of Jia Fu, which contributed to the corruption of Jia Fu. When Jia Fu copied it, he gave him a good kick, which made him feel like a real philistine. This is the villain Jia Yucun described to us by the author. Since then, Jia Yucun has become synonymous with equivalence, treachery, greed, snobbery, forgetting profit and biting the hand that feeds you. Of course, Jia Yucun's image is complicated, and he doesn't look so bad at first, so it is meaningful for someone to discuss the process of this character's ideological change, but at the same time, the author has carefully designed the thread of such a book.
