Actually, it's quite normal. During this time when they had been living with Chiang Xiao, they witnessed that anyone from the Old Chiang Family who came to cause trouble couldn't get the better of her. Seeing Chiang Xiao not endure any grievances and directly rebutting everything, they were somewhat influenced.
So, this time she decided to voice her grievances.
Before anyone else could speak, she continued crying, "Ge Dejun, tell me, since I married into the Ge Family, in what way have I not done well, in what matter have I not followed mother's wishes? Over these years, I've swallowed so much bitterness alone, but I didn't speak out—surely you could see it for yourself, couldn't you? You always tell me to just endure, that she's our mother, and to let things go in one ear and out the other, but many things simply can't be handled that way. Don't you understand?"
