Gu Ning didn't go to sleep after Leng Shaoting left, but disguised herself as "Tang Aining" and went to see Qi Ziyue and Tang Yaxin.
She didn't know that Qi Ziyue was already caught by Tang Bingsen, and she only found that he was absent in the hospital. She thought that Qi Ziyue had already left the hospital.
Since she couldn't find Qi Ziyue, she went to see Tang Yaxin.
Tang Yaxin was still staying in the same ward. Even though many terrible things had happened to her, Tang Yaxin didn't move to another ward or another hospital, because she knew that "Tang Aining" was spying on her.
Ji Yijing had the idea to let Tang Yaxin have recovery abroad, but Tang Bingsen was worried that they might not be able to help her if anything bad happened again.
It made sense, so Ji Yijing gave up the idea.
