A Dream of Red Mansions has high artistic value and research value, which embodies the social system, ethics, education, economy, clothing, diet, architecture, gardens, medicine, health preservation, appreciation, folk customs and other aspects at that time, and has great reference value for us to understand that dynasty. Secondly, it wrote the tragedy of Daiyu and Baoyu on the surface, and secretly wrote the tragedy of the decline of four big families, but it was also a microcosm of the whole society at that time, so it was actually the tragedy of the decline of China at that time. Moreover, literature is of high value, and its writing techniques are changeable and ups and downs. Compared with many novels at that time, it has novel themes and unique writing points. I won't go into details, just a birthday party, Jia Jing's, Jia's, Baoyu's, Wang Xifeng's and Baochai's, but they are all different. After reading it, I will never feel redundant, and even Yuan Chun's birthday has been brushed aside. Finally, his article has many implications, which need careful analysis to find the actual meaning the author wants to express. When I think about it, I will read it again. It turns out that the author has hinted at it. In order to avoid falling into the literary cage, many contents of this novel cannot be directly expressed, so many people like this analysis to understand the author's intention. Every time you read it again, it is enlightening. This is the charm of A Dream of Red Mansions.
