Who knows the situation of Song Bin prison in Harbin? Please, one of you can tell me! thank you

I spent three years in prison, worked as a guard and a secretary. I know how they cheated the prisoners' families of their money. I have the bank card number they provided to the prisoner and the way to cheat money. I have mastered the bloody fact that more than 40 prisoners have been cheated, beaten and abused. Afterwards, I saw it with my own eyes.
