Paying for the liar who dumped the pot?

Guo Qiang and Guo Mei, who are close relatives of Guo Wengui, both know Lao Guo’s character well, and because they are close relatives, they understand more thoroughly. Also because they are close relatives, in order to keep their father, they can testify against the judge in court by perjury. Then Miller, who is not a relative but not an acquaintance, why should he use his “money way” to pay for a liar who has fallen into the limelight and dumped the blame on himself?
