Forcefully Pushed Her Against the Wall

Zhao Yu wanted to ask about the female fish vendor. He specifically wanted to find out if she was one of the victims of the Headless Female Corpses Case. If she was, he could be certain that Tao Xiang was the murderer!

However, when he pondered it a bit more, he finally realized that the female fish vendor's murder happened after Bai Lili's, as Bai Lili was the last victim. So, his guess was obviously incorrect.

Following this line of thinking, he were to suspect Tao Xiang, he only needed to investigate what happened to Tao Xiang before 1988. However, Cui Lizhu was only two years old at that time, so he wouldn't be able to find out anything from her. This was because it was impossible for Cui Lizhu to know about things that happened when she was just a toddler, much less before she was even born!
