The old lady Qin is her biological mother and adopted mother, so she has been calling her grandma.

Because of what happened with Zhou Shengsheng, the old lady Qin felt that the Qin family was sorry for Zhou Shengsheng, so she was not very good to her own daughter, but preferred her mother, so the old lady Qin was also very good to her. Although she is not a grandson, she is better than a grandson.

Daughter:

The hostess of the Zhou family and the eldest son of the Zhou family were supposed to be the heirs of this inheritance, but they never took it home because of the obstruction of their stepmother.

Not only did she know Zhou Shengsheng behind her husband's back, but she also gave birth to Zhou Wensheng, and she was always drooling over Zhou Shengsheng's property.

Wan Qin nominally wanted to find a good wife for Shengchen Zhou, but in fact he wanted to arrange for one of his own to marry Shengchen Zhou, so that he could control Zhou Shengsheng's property in the future.
