Please tell me about your understanding of "Dream of Red Mansions".

"A Dream of Red Mansions" is about a big family. The ancestors of this family once went to war with the emperor, and both brothers were granted duchy status. His elder brother Jia Yan was granted the title of Duke of Ningguo, and his younger brother Jia Yuan was granted the title of Duke of Rongguo. The two mansions were connected and were called Ningguo Mansion and Rongguo Mansion. By the time "A Dream of Red Mansions" begins, the first generation Jia Yan and Jia Yuan have long since passed away, and the second generation Jia Daihua and Jia Daishan have also passed away. Only Jia Daishan's wife Shi Laotaijun (Jia Mu) is still there. Among the many people in the Ningrong Mansion, Jia Mu has the highest seniority. She is the biological mother of Jia She and Jia Zheng, the aunt of Jia Jing, the grandmother of sisters Jia Lian, Baoyu and Yuanchun, the great aunt of Jia Zhen, the maternal grandmother of Lin Daiyu, the great aunt of Shi Xiangyun, and the great aunt of Xue Baochai. The daughter of the Shihou family of the Jinling family has been married to the Jia family for more than fifty years and has enjoyed all the glory and wealth in the world. Although he is now very old and has left the housekeeping to his second daughter-in-law, Mrs. Wang, and his grandson-in-law, Wang Xifeng, and he only takes his grandchildren to have fun and enjoy happiness, he still holds supreme power in Ning Rong's second house. Jia Zheng blamed Baoyu, and she threatened to "go back to Nanjing immediately", so Jia Zheng "begged to plead guilty"; Jia She wanted her maid Yuanyang to be a concubine, but she scolded her and had to "sue" I am sick and dare not see Jia Mu." As for Wang Xifeng and others, they tried their best to please her and surrounded her like stars holding the moon. Although Jia Mu is not the central character in "A Dream of Red Mansions", she is the central character in the Rongguo Mansion. The daily life in the mansion revolves around Jia Mu: eating wine, listening to operas, playing cards, visiting temples, making Jiaos, worshiping at ancestral halls, etc. Telling jokes, making lantern riddles, and drinking wine... The author's detailed description of daily life in the duke's mansion allows us to truly understand the real life of the nobles at the end of feudal society.
