In 《红楼梦》, Jia Mu&;s feelings for Lin Daiyu are not unchangeable, but rather complicated, which can be divided into three stages: missing period, intimacy period and boredom period. The first stage, the distant missing period. It is a traditional habit and a manifestation of human nature to live apart from each other. Grandmother Jia loves her daughter Jia Min the most, while Daiyu is Jia Min&;s daughter. Grandmother Jia loves her daughter and naturally loves me, love my dog. When Daiyu&;s mother, Jia Min, died, the grandmother was sad and suffered from a long distance, so she transferred the guilt of not being able to protect her daughter to her granddaughter, Daiyu, worried that Daiyu was young and sick and lonely, worried that Daiyu was unloved, and worried that Daiyu&;s education was lagging behind, so she sent someone to pick her up again and again. Although Daiyu was worried about her father, Lin Ruhai, she was eventually taken into Jia&;s house. The second stage, the sweet period of first meeting. Daiyu&;s face value, inner beauty and understanding all add love to Jia Mu. Especially when Jia Min was ill, she was only six or seven years old, but she served soup and medicine, and she was a very good tutor. When I first met Daiyu, Grandmother Jia&;s feelings were undisguised: &”;When Daiyu entered the room, I saw two people holding a silver-haired one to meet her, and Daiyu knew it was his grandmother. When Fang wanted to meet him, he was put into his arms by his grandmother, and he burst into tears. At present, all the people standing underground hide their faces and cry, and Daiyu can&;t stop crying. &”; After moving into Jiafu, the Lady Dowager showed an obvious preference for Daiyu, including the people around her, who were like stars holding the moon. This can be seen from the performance of Wang Xifeng, who is good at observing words and feelings. She is well-dressed and everywhere. The third stage is the weariness of getting along for a long time. Therefore, Grandmother Jia loves Daiyu and Baoyu. But in contrast, Jia loves Jia Baoyu more. After all, Jia Baoyu is the grandson of Jia Mu&;s first relatives, with the same surname Jia. Daiyu is just the granddaughter of Jia Mu, surnamed Lin. Especially after getting along for a long time, Daiyu&;s shortcomings stand out one by one: being ill, being small-minded and easy … All these things are in the eyes of Jia Mu, and they will naturally weigh the pros and cons. To sum up, Grandmother Jia doesn&;t want Baoyu to marry Daiyu for three reasons: 1. For the sake of carrying on the family line. Daiyu&;s illness naturally affects the continuation of offspring. 2. For the sake of family management. Daiyu is simple, scheming, narrow-minded, not good at coordinating relationships, and she is not as versatile as Baochai. 3. For the sake of family interests. Compared with the Xue family, the Lin family is four big families. If they are married, they will join forces and belong to a win-win situation. In a word, for the sake of Baoyu&;s long-term development, the Lady Dowager certainly won&;t let Baoyu and Daiyu be together.
