Why did Aunt Zhao in A Dream of Red Mansions finally become a rebel?

In A Dream of Red Mansions, Aunt Zhao was finally kicked out of Jia's house by Mrs. Wang. Because there was no one to support her, Aunt Zhao finally starved to death on the street.

And aunt Zhao will end up like this. I think it has something to do with my daughter Tanchun's distant marriage, because Aunt Zhao's status as an aunt will not be so valued in the Jia family, especially after Tanchun, the only person who can rely on, is far away.

With Jia Fu's copying, Aunt Zhao made an object that stabbed the villain, which directly hurt Wang Xifeng and Jia Baoyu, who was in the heart of Lady Wang. Seeing that her children were treated so viciously, how could Mrs. Wang, the housekeeper, let Aunt Zhao go easily?

In addition, Aunt Zhao Can became Jia Zheng's concubine room, which was also bought by certain means. This is like a thorn in the heart for Mrs. Wang of Jia Zheng, so Aunt Zhao's ending is actually due to her own cultivation.
