Similarly, Tony Leung Ka Fai's "The Ancient Confused Lawyer" was indeed framed, but the person who framed him was not a policeman, and was finally acquitted because he won the case.
After thinking about it, I thought of a power supply, "Pork in a Prison", in which the protagonist reported the evidence of police corruption in the newspaper.
He was framed by the police and sent to prison. His girlfriend went to intercede and was abused by the police and his men. The hero of that play is not Tony Leung Ka Fai, but Tony Leung Chiu Wai.
