The real purpose of why Qiao Yu came back to this area was to find out where exactly Qiao Mei and Li Gui lived. Only by knowing their location would she have a chance to make a comeback in the future.
She felt that she had already gathered a lot of evidence against Qiao Mei. As long as she used everything she had to threaten Qiao Mei, Qiao Mei would have to give her whatever she wanted. She could then take over the courtyard house which Su Yang's family used to live in. In the future, Su Yang would definitely follow her around like a dog and would be willing to take care of her for the rest of her life.
She had previously seen Su Yang's family making trouble with Li Gui. They must know the exact location of Li Gui's house. In the future, once she had the chance, she would ask him indirectly. It would be much easier than if she had to go and look for them from house to house.
