That year, after she had asked a few people to investigate the accident, she found out that her aunt, Zhao Wei has been talking to the manager of Rising Company.
After talking with the manager, he had admitted to taking bribes to change the materials. Li Qin Yao had threatened to bring the manager to the police and after a while, the manager agreed to testify against her second aunt.
That manager was the person she had seen in Y City last night. Manager Guo.
Two years ago, a day before Manager Guo could testify against her second aunt, he disappeared, leaving his wife and daughter just like that.
Li Qin Yao had tried to find him, but could not find any lead. The investigators had suspected that perhaps Manager Guo was murdered and Li Qin Yao could not shake off this possibility until she had seen him again last night.
