In the original novel, the reason why the old lady of the Wang family finally gave up on Aunt Kang was because Aunt Kang had the support of a higher power. Aunty Kang's father was a wealthy local businessman and had made an oath with her mother to provide a certain amount of dowry for her son's marriage. However, after Aunt Kang married into the Wang family, her mother died unexpectedly, causing Aunt Kang's power to gradually decline. As the old lady of the Wang family's son, Ming Lan, was a competitor of Aunt Kang, she was worried that Aunt Kang would pose a threat to her. In addition, Old Mrs. Camden had also heard that Aunt Kang's mother had a bad impression of her and that she had once tipped her off. This made her even more worried about Aunt Kang's power. After considering the above factors, the old lady of the Camdens decided to give up on Auntie Kang and let her leave the Camdens. She would not have any more interactions with her anymore.
