When Cao Feiying gave birth to her son, she suffered from a difficult labor and hurt her body. Therefore, it would be very difficult for her to have another child in the future.
Cao Feiying, who was aware that there was no hope for her to give birth to another daughter, saw that her in-laws liked girls so much. Therefore, after Chen Meng'er, the only girl in the Qu family, was taken away, she also thought of bringing up the daughter of her elder brother by her side and letting her niece win the favor of her in-laws. She wanted her to gain a firm foothold in the Qu family.
Unfortunately, she too late. Matriarch Murong was one step ahead of her and sent Murong Qi to the Qu family to stay by Murong Ying's side.
