Knowledge expansion:

A Dream of Red Mansions records the history of the rise and fall, honor and disgrace of the feudal family represented by Jia Fu, describes the love of young men and women headed by Bao Dai, and depicts the fate of twelve women in Jinling. However, there is a person who does not belong to the Grand View Garden but is vividly portrayed by the author-Grandma Liu, a village girl. Cao Xueqin, the author, spared no effort to describe such a granny Liu who was out of harmony with the surrounding environment and characters when describing the Second Mansion and the Flower Beauty Grand View Garden.

When the author Cao Xueqin carefully arranged the artistic structure of A Dream of Red Mansions, he chose a village woman, Granny Liu, who was far from Jia's position, instead of telling the story directly and letting Granny Liu play the role of threading the needle. ?

As soon as Granny Liu entered Guo Rongfu, she heard and saw that Guo Rongfu was a magnificent scene on the surface. As soon as she entered the door, she officially unveiled the story of A Dream of Red Mansions, and began a profound description of real life and an anatomy of the society at the end of feudalism. ?

If granny Liu's entry into the mansion is only the beginning of the whole story of A Dream of Red Mansions, then her second entry into the mansion has penetrated into many corners of Jia's house, which has led to various aspects of Jia's house, such as food, clothing, housing, transportation and play. This time, Granny Liu met more people and saw more scenes, which made her feel more amazing than the first time. The role has also changed from a relative of the Wang family to a guest of the Jia family, attending the rich family banquet of the Jia family and visiting the Grand View Garden. Through granny Liu's observation, experience and comments, the author further shows the enjoyment and luxury of the Jia family, not only describes the prosperity of the Jia family, but also lays the groundwork for the decline and rescue of the Jia family in the future. ?

When Granny Liu entered the mansion three times, Jia's mansion was in ruins. The ancestors of the Jia family died. Xifeng, who has always been fierce, was so ill that she had to entrust her only daughter to the poor old woman who had twitched. ?

It can be said that Granny Liu is not only the introduction of the full text of A Dream of Red Mansions, but also the clue that runs through the whole text. Granny Liu's three visits to the mansion are the turning point of Jia family's prosperity and decline. That is to say, whenever there is a major turning point in the plot of A Dream of Red Mansions, Granny Liu will appear in the mansion.
