In Cao Xueqin's conception, the plot of Lin Daiyu being forced to marry the Prince of Beijing or being engaged to him did not exist. Cao Xueqin's novel 'Dream of the Red Chamber' was a fictional story in which the plot and characters were formed according to the author's own imagination and creative ideas. Therefore, whether Lin Daiyu was forced to marry the Prince of Beijing or engaged to him was not clearly stated in the novel. However, we can analyze from the plot and character in the novel that Lin Daiyu marrying Prince Beijing or getting engaged to him is a possible plot. In the novel, Jia Rong, the second son of Jia Zheng, the Prince of Beijing, was nominated as Jia Baoyu's marriage partner. Lin Daiyu was also a highly valued girl in the Jia family, so there was a certain relationship between Lin Daiyu and the Prince of Beijing. In addition, the novel also described some characteristics of Prince Beijing, such as his integrity, gentleness, kindness, etc. These factors hinted that there might be some kind of relationship between Lin Daiyu and Prince Beijing. However, these plots were only plots in novels and did not represent real historical facts. Whether or not Lin Daiyu would eventually marry the Prince of Beijing or be engaged to him still needed to be analyzed and judged based on the historical background and actual situation.
