If all the rich and powerful can hire body doubles to do their prison time, why would they lose their lawsuit?
Because the people demand a win in the court against the rich and powerful. Once the verdict is out, the people are happy. Give a few months to a year give or take, the people will forget what happen (temper goes down), the rich is out but not necessary in plain sight everyday (semi-hiding), and the body double is in the prison.
As a Chinese whom know a lot of real dark side of this country, I must say this report is just a joke. There may be 10 or 20 cases in the whole China for a decade, but exaggerating to that level is just a joke. Maybe people want to see this kind of story.
