What is their feeling about Adeline that Big sister has. Why does she hates adeline. and page number

"'But then Mama died giving birth to you. If you had not been born, Mama would still be alive. She died because of you. You are bad luck.'"

Chinese Cinderella, p.3

The first lines we hear from Big Sister set the tone of both the novel and the character. The blame that rests on Adeline from her birth prohibits any hope of an easy childhood; with her siblings believing that she brought about the end to their idyllic lives, she is in no position to convince them otherwise. The endless cycle of hate and bias has already begun, fed by any negative turns or disappointing results. Although this is brutally unfair, it--like being a daughter and being Chinese—is a part of realities that Adeline has no choice but to overcome.
