Grandma Jin achieved her goal.

In the TV series "Adoptive Father", Grandma Jin refused to let Xiaoyu go home.

First, when Xiaoyu was young, nothing went right with her father. Xiaoyu's grandmother asked someone to tell her fortune, and the fortune teller said that Xiaoyu ordered the men at home, so Xiaoyu got lost when Xiaoyu and Grandma Jin went to see Grandma Jin's sister, and didn't want to find Xiaoyu again.

Second, Grandma Jin has always wanted a grandson, but Xiaoyu is a girl, so she doesn't like Xiaoyu.

Third, Xiaoyu's mother and Grandma Jin have been separated because of Xiaoyu's loss, for fear that Xiaoyu knows that Xiaoyu is lost because she doesn't want to get it back.
