Why is Mrs. Wang's sister surnamed Xue?

Aunt Xue, Mrs. Wang's sister, is surnamed Xue. Reason:

Aunt Xue, Mrs. Wang's sister in A Dream of Red Mansions, is not surnamed Xue. Her surname is Wang, but she married the Xue family and became the mother of Xue Baochai and Xue Pan. In order to distinguish themselves from Mrs. Wang, these children call her Aunt Xue. That's what we call it among ordinary people, such as Zhang's wife, whose name is Zhang Sister-in-law, but her own surname is not Zhang. This is from my husband.

That is to say, in A Dream of Red Mansions, Mrs. Wang and Aunt Xue are sisters, and both of them are lovely daughters of the Wangs, one of the four big families. Mrs. Wang married Jia Zheng, who is a direct descendant of the government. Jia Zheng is also an official and a five-product foreign minister. Aunt Xue's husband is an imperial businessman.

Aunt Xue's ending:

Aunt Xue was kicked out of Jia's house. Aunt Xue knows that Er Yu's affection is the first. If she keeps pushing her daughter up, all three people may not be happy, and she will not be without such consideration. So it may be because of affection that she said that to Dai Yu, and she rushed to that point.

However, because of Mrs. Wang's calmness and reason, perhaps Aunt Xue will soon wake up and continue to make suggestions for Jinyu's marriage. The idea of the so-called four corners will naturally be shelved.
