In A Dream of Red Mansions, the relationship between Granny Liu and Jia Fu began with the son-in-law Wang Gou. Wang Gou's ancestors used to be a small official in Beijing. Because they were all surnamed Wang, they took the opportunity of "being an official in one place" to "join the family" and became "members of their own family". So the Wang dog family married the Jia family, a rich family. Later, it happened that the Wang dog family failed to live up to expectations, which made the family business depressed and moved out of the city to live in the countryside. By the end of the winter of 2008, Wang's dog family had nothing to do, so her mother-in-law granny Liu had to take advantage of this relationship to go to Jia's relatives and seek relief, so granny Liu staged this play as soon as she entered the house.

So, in fact, Granny Liu has nothing to do with Grandmother Jia, but has something to do with Wang Xifeng, who is in charge of receiving Granny Liu in the story.
