The story of " A Golden and Jade Match " in " Dream of the Red Chamber " was considered a lie mainly because there were some illogical and contradictory aspects in the plot setting and character creation of the novel.
In the novel, Jia Baoyu and Lin Daiyu were destined to be together, but there was no real emotional foundation between the two. Instead, it was a misunderstanding and contradiction caused by family power, social status, and other factors. In addition, Lin Daiyu's personality also made it difficult for her to become Jia Baoyu's wife. She needed more love and support than a simple marriage partner.
In the novel, the " golden fate " was also described as an unrealistic dream that contradicted the concept of marriage in reality. At that time, marriage was more of a marriage between families and an exchange of interests rather than a marriage based on love and feelings. Therefore, the setting of the "golden and jade fate" was also considered to be a criticism and reflection of the social reality at that time.
To sum up, the story of " A Golden and Jade Match " in " Dream of the Red Chamber " was considered a lie because there were some unreasonable and contradictory aspects in the plot setting and character creation, and it was also contrary to the concept of marriage and values in reality.
