After Zhou Hongwei was arrested, Old Master Zhou said, "The one who unties the bell must be the one who ties the bell". That clarified the minds of the Zhou Brothers.
Zhou Hongwei was arrested and convicted. The key witness in his case was Xiao Lingyu.
However, Xiao Lingyu was extremely sensitive or extremely lucky. All the people sent by the Zhou Family couldn't find her.
The Zhou Family knew where Xiao Lingyu stayed and where Xiao Lingye attended school, so they should be able to find her easily. But that was not the case.
When Zhou Hongwei was arrested, Xiao Lingyu requested protection from the police until Zhou Hongwei was convicted. Jiang Tao knew her intention immediately. Xiao Lingyu's evidence was the most important in Zhou Hongwei's case.
The Zhou Family was a powerful family in Xing Yin County, but Xiao Lingyu was just a normal person. Therefore, her personal safety and the safety of her family were greatly threatened.
